Casval Rem Deikun

Kycilia Zabi is the only daughter of Degwin Sodo Zabi. As the Earth Sphere moved towards war, Kycilia was given high military command in the Zeon field forces at the age of 24. Taking over the Zeon Army's Mobile Assault Force, she sets herself up on the Lunar cities and brings under her control various aspects of the Zeon war effort like; Special Operations, Research and Development, and Espionage. She creates several special military units throughout the war and commands a sizable fleet from her Lunar HQ. {character} eventually shoots a rocket launcher into the bridge of the ship she is riding in, ending her life.

Degwin Sodo Zabi is the absolute dictator of the Principality of Zeon. He was instrumental in establishing the Republic of Zeon with his ally Zeon Zum Deikun. Degwin was Zeon's chief of staff and claimed that on his deathbed, Zeon, with his dying words, declared Degwin his successor. Degwin Zabi is suspected by most to have a hand in the sudden death of Zeon Deikun, although nothing concrete has ever been uncovered. Gihren, Degwin's eldest son, initiated a purge of Deikun loyalists, while Degwin Sodo Zabi declared Side 3 colony the Principality of Zeon and himself as Sovereign. However, as time passed, he began to feel a sense of emptiness, and at the outbreak of the One Year War, he handed over all power to his children and became politically retired. Degwin is also consumed by the intrafamilial feuding between his ambitious children, most notably Gihren and his daughter Kycilia. Also, Degwin never recovers from the death of his youngest and most spoiled son, Garma. He falls into a depression since Garma was his favorite child, and leaves most of the day to day operations to Gihren. As a result, Gihren effectively becomes the self-styled "Führer" of Zeon, taking all of his father's remaining power, leaving Degwin as little more than a figurehead.

Gihren is best described as ambitious, underhanded, overconfident, and a motivator. As the essential leader of Zeon, Gihren belittles the dwindling power of his father and continuously schemes to turn the One Year War into a total war. Sticking to the homeland of Side 3, Gihren mostly hands orders to his other siblings and expects them to succeed without failure. Though highly talented, this also affects his realism, relying solely on overwhelming firepower and prototype machines to achieve victory. Gihren was ultimately killed by his sister, Kycillia, bringing a close to the One Year War.

Tall, burly and scarred, Dozle casts a fearsome appearance at first glance but he is actually one of the more likeable of the Zabi clan. Gregarious and good natured, Dozle is a good man to his troops. He is also a devoted, loving family man and has a wife Zenna and baby daughter Mineva (It must be noted that he also took a young woman named Marlene Karn as his mistress, half for her beauty and half to help her father Maharaja Karn). Dozle is closest to his younger brother Garma Zabi and actually looks forward to the day when Garma becomes an Admiral in his own right. Dozle dismisses {character} from his division, blaming him (though not suspecting him of foul play) for incompetence in the battle that resulted in Garma's death. Dozle especially despises his sister Kycilia Zabi and this feeling is only increased when she recruits {character} into her division. Eventually, Dozle was killed by Amuro Ray.

Garma Zabi was the fourth child of the Zabi family and the commander of the Principality of Zeon Earth Attack Force during the One Year War. Garma was extremely popular among the people of Zeon. It was said that this was not only the result of his appearance and Zeon propaganda, but also because he possessed a natural charisma. Underneath the glamorous exterior, however, Garma was defined by a constant need for validation, both from the rest of the Zabis and the people of Zeon. Being a member of Zeon's ruling family, and having become the supreme commander of the Earth Attack Force at such a young age, he was determined to prove that he did not receive his position based on family connections alone. In private, Garma demonstrated a purity and immaturity befitting of his age, going as far as promising to his lover Icelina Eschonbach that he was prepared to abandon Zeon to marry her. He also genuinely considered {character} a dear friend, completely unaware of {character}'s ulterior motives even as {character} set Garma up to be killed by the Gundam.

{character}'s archrival since their fateful encounter during the One Year War. {character} and Amuro had their first encounter during the latter's escape from Side 7 with the crew of the White Base, though they did not see each other's face as they were piloting their mobile suits at the time. From that battle onward, {character} would repeatedly challenge Amuro whenever they encountered one another on the battlefield, as Char wanted to defeat the Gundam in battle. He would meet Amuro face to face for the first time at Side 6, and while it is implied {character} knew who Amuro was, he let him go, wanting only to best the young man in the battlefield. Thus, their rivalry was one of pride: both wanting to outdo the other. During the Gryps War, {character} and Amuro reunite after seven years, this time both on the same side. {character} seemingly has let go of his hatred for Amuro, as he no longer displays any ill-will towards Amuro. The two were even able to hold a conversation and {character} did not even react badly to Amuro's joke of the Zeon Family being made to be sacrifices, laughing instead. Both of them also compare how similar Kamille Bidan's relationship with Four Murasame was with their past relationship with Lalah, and they express their common desire that Kamille should not go through the same trauma they had. Though Kamille's rival Jerid Messa ended up killing Four, both of them get their wish since Kamille doesn't believe in holding grudges.

Sayla Mass, or more accurately Artesia Som Deikun, is the sister of {character}. Unlike her brother who went adrift and changed his alias several times, Sayla retained hers, and became a member of the Earth Federation. {character} was shocked when he learned of this, as she was to learn that he was the "Red Comet". {character} cares deeply about Sayla as a sister and tries at several points throughout the One Year War to convince Sayla to leave the Earth Federation military, to no success. Late in the conflict he even goes so far as to give her a case of gold bars telling her to use it to secure her future in civilian life, however despite even this dramatic display of concern she does not acquiesce, instead she chooses to inform Bright Noa of their relationship as siblings. As Sayla is not placed directly in latter conflicts, {character} did not have the same interactions with his sister. During the Gryps Wars, Sayla is shown to have been listening to his speech in Dakar as he gave it live, thus implying that she still showed a concern and strong enough interest in the actions of her brother and that she likely knew of his plan to seize the assembly in advance.

Lalah Sune was a Newtype from the Flanagan Institute that {character} took an interest in and chose to train on the battlefield. He takes some effort to stay together with her and have her watch over his battles from a distance until eventually he deploys to support her when she is in her Elmeth. As time passes the two develop feelings for one another, despite the fact that Lalah and Amuro have a stronger connection as Newtypes than she and {character}, this being likely both because of the nature of their Newtype resonance and the fact that Amuro is in fact a stronger Newtype than {character}. Amuro kills her accidentally during battle with {character}. When Lalah dies protecting {character} from Amuro's beam saber, he is filled with grief and his obsession to defeat the Gundam also becomes a quest for revenge, despite that it was her and not Amuro's action that resulted in her death. Following her death, both Amuro and {character} remain focused on her memory and the remnants of her consciousness that still remain in space. Whereas Amuro is afraid to go into space for many years for fear of encountering her ghost, {character} chooses to remain there. While he can sense her presence up until he encountered Kamille he always believed that any Newtype presence he felt in space to be either hers or Amuro's. In the end, he was not haunted by her ghost, nor was he able to sense more than a glimmer of her presence in his time in space.

A Newtype is a person who has reached a new stage of human evolution. The theory behind this minor but groundbreaking metamorphosis is: in order to adapt to life in space, the human body evolved with heightened mental awareness. As such, Newtypes tend to appear among Spacenoids, although not exclusively. Newtypes have an extremely high degree of focus and spatial awareness, almost a sixth sense. They are capable of empathically detecting other Newtypes and are sensitive to the hostile intentions directed at them by others, allowing them to uncannily react to their opponents even before the offender carries out the intended action. Some Newtypes also exhibit telepathic abilities or use psychokinesis.

The One Year War was the culmination of the hostilities between Side 3's Principality of Zeon and the Earth Federation. Relations between the two had been strained since Side 3 declared themselves the independent Republic of Zeon under the leadership of Zeon Zum Deikun, and had only worsened since Deikun's death and the Zabi family's rise to power. Declaring themselves the Principality of Zeon a year later, and brutally purging Zeon Deikun's remaining followers, Side 3 became increasingly hostile to the Earth Federation. Zeon entered a state of national mobilization, dividing their military into a Space Attack Force under the command of Dozle Zabi and a Mobile Assault Force under the command of Kycilia Zabi. In January UC 0079, the Principality of Zeon officially declared war on the Earth Federation when the Principality of Zeon launched surprise attacks against the Earth Federation-controlled Sides. During the fierce fighting in the first month of the war, weapons of mass destruction were used indiscriminately, with Zeon forces deploying G3 Gas in inhabited colonies, attempting a colony drop against the EFF's headquarters at Jaburo during Operation British, and the Principality of Zeon using nuclear weapons during the Battle of Loum. During this period of fighting, each side lost nearly half of their respective populations. After this, both parties agreed to sign the Antarctic Treaty which, among other things, forbade the use of weapons of mass destruction.

The Principality of Zeon launched a surprise attack against Side 1, Side 2, and Side 4 on January 3, UC 0079. Attacking a mere three seconds after officially declaring war (a fact that was sardonically referred to as the "three-second warning"), the Zeon used their mobile suit forces to eliminate Earth Federation Space Forces resistance before killing the civilian inhabitants of a number of colonies with poison gas. This period of initial slaughter became known as the One Week Battle or One Week War. It was during this time that Side 6 declared its neutrality in the conflict. The peak of the One Week Battle was "Operation British", which took place on January 10, UC 0079. Zeon forces used the depopulated colony cylinder Side 2, Bunch 8 ("Isle Iffish") in an attempt to destroy the Earth Federation Forces main headquarters, Jaburo. Though the Earth Federation Space Forces dispatched a fleet of their surviving warships, and even made at least a nuclear strike, in an attempt to stop the operation, the Zeon military successfully defended the colony, and the EFSF was forced to withdraw after taking near-total losses. Upon entering the atmosphere, however, Isle Iffish broke apart, missing Jaburo but causing widespread destruction across Earth. The largest remaining piece of the colony, consisting of approximately the entire front half, hit Sydney, Australia, completely wiping out the city and causing massive damage across the entire continent. Operation British was a complete failure.

After the failure of Operation British, Zeon forces attacked Side 5, also known as Loum, on January 15, UC 0079. Beginning as an attempt to drop a second colony, the operation quickly turned into a full-scale fleet battle when the majority of the surviving Earth Federation Space Forces, commanded by General Revil, counterattacked. Zeon used nuclear weapons in this battle, causing horrific loss of life not only among the combatants, but resulting in the complete destruction of Side 5 as well. The Earth Federation managed to halt the attempted colony drop and inflict significant losses on the Zeon forces but they were unable to prevent the destruction of Side 5. While the EFSF were able to evacuate a few million Side 5 inhabitants before the battle began, in the end, their forces were annihilated during the battle. The Battle of Loum marked the first time that mobile suits showed their true potential in combat, proving to be terrifyingly effective against the Earth Federation fleet. General Revil was captured by the Black Tri-Stars and several other Zeon pilots (most notably {character}, Shin Matsunaga, and Johnny Ridden) first made a name for themselves as mobile suit aces.  The Federation's losses were heavy. Over 80% of its deployed forces was lost, with only 42 vessels surviving the battle. Meanwhile, the Zeon fleet sustained far less damage thanks to the deployment of mobile suits, losing only 8 battleships and cruisers, with another 16 heavily damaged and 14 moderately damaged.

After the atrocities of the One Week Battle and the Battle of Loum, with nearly one-third of humanity dead, the Earth Federation and the Principality of Zeon met in Antarctica to discuss terms of peace. The Federation, having suffered major losses to its space forces at Loum as well as the loss of more than one billion of its citizens in less than a month, was ready to consider surrendering to the Principality of Zeon. However, during the negotiations, General Revil escaped from Zeon's custody and returned to the Earth Federation, giving his famous, "Zeon is exhausted!" speech detailing the poor condition of Zeon's military after the heavy fighting. In large part due to this speech, the Earth Federation refused to surrender at Antarctica, instead negotiating for several important agreements. The use of weapons of mass destruction—including the use of nuclear and chemical weapons, as well as colony drops—was declared forbidden, rules for the humane treatment of POWs were agreed upon, and the neutrality of uninvolved parties such as Side 6 and the Jupiter Energy Fleet were guaranteed.

Following the bloody One Week War, the Federation and Principality signed the Antarctic Treaty, forbidding the use of Nuclear, Biological, and Chemical (NBC) weapons. While this narrowed the range of strategic options, it also gave a distinct advantage to the Principality Army, whose plans were centered on the use of Mobile Suits. Upon realizing that the war was becoming a long, drawn-out battle instead of a sudden, quick strike, the Principality of Zeon decided to invade Earth. One week later, the Principality commenced its assault on Earth itself, using the Mass Driver, an electromagnetic "catapult" on the lunar surface, to send their MS into space and Earth. In February they began to organize an Earth Attack Force under the command of Garma Zabi, the youngest member of the Zabi family, divided into five MS divisions with distinct goals. Beginning on March 1, the newly formed Earth Attack Force began staging drop operations to land troops on Earth; over the course of the next month, they would complete a total of five drops, landing in central Asia, North America, Australia, and northern African and the Middle East.

The first group dropped on Central Asia, wiping out the Federation's Baikonur spaceport. They then advanced to the Caspian Sea, moving west into Europe and south into the Middle East. The second and third groups were dropped on both coasts of North America with two objectives: 1) to subjugate the Federation's industrial military complex. 2) To take over the Federation food supply. The California Base (a generic term for the more than 20 military bases along the west coast) became the staging ground for subsequent terrestrial assaults. As the bases were captured without damage, they were soon converted to production of Zeon MS. The fourth group, aided by support troops already on Earth, occupied many islands of the Oceania region for the procurement of resources. Up until then, the Principality faced a distinct disadvantage in resource availability, having to rely on Lunar and asteroid mining. The fifth and final group landed in the largely unprotected deserts of North Africa. With facilities, food, and resources at their disposal, the Principality was set for global conquest. From these drop locations, the Zeon army spread across the planet, using captured facilities and material (notably including the Earth Federation's massive California Base) to strengthen their military power. Within a few months, Zeon controlled most of Europe, Asia, and North America. With the Federation forces scattered and their numbers decimated, their outlook was grim though the efforts of special units like the Semovente Corps and anti-mobile suit special tactical squads helped stem the tide on Earth

During Zeon's offensive on Earth, the Earth Federation was desperately trying to develop mobile suits of their own. Project V was a result of this; a top-secret Earth Federation Forces research project aimed at producing mobile suits for the Earth Federation, while the Vinson Plan was enacted to rebuild the Earth Federation Space Forces. A major breakthrough of Project V was the development of compact, mobile suit-sized beam weapons, giving a mobile suit the effective power of a battleship cannon. Three prototype designs were completed under Operation V; the long-range tank-like RX-75 Guntank, the mid-range support RX-77 Guncannon, and the close combat-oriented RX-78-2 Gundam. The suits would be stored on the Federation's newest battleship, the SCV-70 White Base, the first Federation warship to not only carry mobile suits, but also able to operate on Earth and in space.

Operation Odessa was the Earth Federation Force's first major offensive campaign on Earth. The opportunity for the Federation to strike back opened up with the death of Garma Zabi. Operation Odessa used 30% of the Federation Army to take out the Zeon mining facilities in the Odessa region; the lynchpin of the Principality supply network. The operation was launched on November 7, ending two days later in victory for the Earth Federation. This was remarkable for the fact that the Earth Federation Forces consisted almost entirely of conventional troops, tanks, and aircraft, yet managed to defeat a Zeon force consisting of many mobile suits. The Earth Federation did deploy a small number of mobile suits, but they were mainly used in mop-up operations and contributed relatively little to the battle. Operation Odessa marked the turning point of the One Year War; the beginning of the end for Zeon's forces in Europe and Asia. However, the leader of the Zeon mining operations, Colonel M'Quve, had enough mining material sent to the Zeon homeland to allow the Principality to continue the war without the danger of supply shortages. This battle was the largest and the bloodiest on Earth, where the Earth Federation relied heavily on conventional weapons such as tanks, bombers, fighter craft, a small number of MSs (30 units), and a large number of troops (3,700,000) compared to the smaller but much better equipped Principality of Zeon army; who fielded only a relatively small amount of fighters, bombers, tanks, and artillery, but over a hundred MSs which were more advantageous.

On November 29, White Base finally reached the HQ of Earth Federation forces, Jaburo. At the same time, {character} found the main entrance of Jaburo. Zeon began their initial attack by launching air raids. {character} led a commando squad to infiltrate Jaburo through another way after wiping out a guard post with a squad of MSM-04 Acguys. {character}'s squad found the GM manufacturing factory inside Jaburo and planted bombs on the GMs, which were found by the orphans from White Base. The following morning, California Base sent several Dopps and Gaws to attack Jaburo, air-dropping many MSs while several marine-type MSs attacked Jaburo through the river. However, Zeon underestimated Jaburo's defenses. The Federation officers agreed that White Base's presence would lure their enemy to Jaburo and had prepared a heavy defense against Zeon, part of which included introducing some of the newly mass-produced GMs to overpower them, though not without losses. The defenses at the spaceport were the strongest, since White Base was docked there, and the defenders put up stiff resistance as it was expected that White Base would bring the war to an end. {character}, defeated in a duel against the RX-78-2 Gundam piloted by Amuro Ray, retreated from Jaburo alongside the other Zeon forces. After the Battle of Jaburo, most of the Zeon military began retreating to space, leaving only the Zeon troops in North Africa and Australia to continue their resistance.

The White Base launched back into space, a Zanzibar commanded by {character} caught up with it, only to let the nearby Zeon patrol, the Camel Patrol Team led by {character}'s ex-lieutenant Dren engage White Base. By this time, Zeon had replaced their Space Attack Force's mainstay Zaku II with newer MS-09R Rick Dom. Instead of cutting off White Base's route of providing decoy, the whole patrol team was wiped out by White Base's forces. After the battle, White Base went to Side 6 for repairs. Space Attack Force's commander Dozle Zabi, worried about the Earth Federation Space Forces build-up at Luna II, dispatched the Conscon Fleet to trap the White Base while he remained stationed at Solomon to observe Federation's movements. On December 5, Dozle's Conscon Fleet reached Baldur Bay of the neutral Side 6, as White Base was docked in that neutral colony side. White Base left Side 6 and engaged the Conscon Fleet. White Base attacked a Musai-class cruiser and destroyed it a very few moments after it exited Side 6's perimeter. Conscon berated White Base for playing dirty and ordered a full-out attack, but lost 12 Rick Doms within 3 minutes, most of them to the Federation's infamous Gundam. The Rick Doms were no match for Amuro, as his Newtype abilities were growing stronger, making his reaction time much faster. Conscon's Chivvay-class was destroyed by Amuro, who charged it after destroying the Rick Doms.

On December 14, Operation Cemballo began with the launch of a new Earth Federation fleet from their fortress Jaburo. Sending their new fleets into space, the EFSF moved towards the Zeon homeland at L2. Standing in their way was the Zeon defensive line, consisting of the asteroid space fortresses Solomon and A Baoa Qu, as well as the lunar city Granada. On December 24, UC 0079, the EFSF fleet launched an attack on the asteroid base Solomon, the headquarters of Zeon's Space Attack Force. Using their Solar System, the Earth Federation inflicted heavy damage on the enemy fortress and was able to take Solomon. When it was clear that the battle was lost, Zeon Space Attack Force's Vice Admiral Dozle Zabi gave the order to evacuate the base and sortied in the Big Zam to fight a delaying action. He succeeded in allowing many Zeon forces to retreat, but was killed by Amuro Ray in the process. The capture of Solomon marks the end of Operation Cemballo, and this event is also known as the "Battle of Solomon".

Solomon is situated at Lagrange Point 5, amid the ruins of the Side 1 cluster. The area of space surrounding the asteroid is known as the "Sea of Solomon", giving the fortress its name. The asteroid itself resembles a 6-pointed star polyhedron or an octahedron in general shape, with most viewpoints of it having the silhouette of a four-pointed star. This shape could sometimes be interpreted as being able to defend against attacks from the front, rear, right, left, top, or bottom, the endpoints of the asteroid corresponding to the vertices of an octahedron. Solomon was one of the Principality of Zeon's asteroid fortresses, serving as the frontline base of Dozle Zabi's Space Attack Force. It is from here that Zeon launched its first attacks against the Earth Federation during the opening days of the One Year War. From this strategic base, the Principality's space fleets carried out numerous sorties against the Earth Federation Space Force. As such, it became a priority target for the Earth Federation as the war began to shift back into the Federation's favour. After the battle, Solomon was used as a staging area for the EFSF's invasion of the Principality of Zeon's home territory and was renamed Confeito. As the war came to a close, Confeito remained a base for the Earth Federation and in U.C. 0083, was the chosen site of a full-scale naval review. This made it the main target for the Delaz Fleet during Operation Stardust. Zeon ace Anavel Gato used the RX-78GP02A Gundam "Physalis" to attack the naval review at Confeito with an MK-82 nuclear warhead, destroying or crippling two-thirds of the Federation's naval forces that took part in it. Despite the damage sustained, the asteroid continued to be a prominent military base used by the Earth Federation. During the Gryps War the base was operated by the Titans, and used to develop the RX-121 Gundam TR-1 ［Hazel］.

A Baoa Qu was the Principality of Zeon's largest and most powerful asteroid base. Much like Luna Two and Solomon, it was originally transported from the asteroid belt for mining and resource extraction, but it was captured and transformed into a military base by Zeon forces, with the space fortification work completed within six months time. A Baoa Qu was a fusion of two asteroids into one, shaped like a disc and a weight, forming an umbrella-like shape; its size is about 33.75 km tall and 22.5 km in diameter. At the top-centre of the asteroid stands a lone enormous tower (though small in relative scale to the space rock it is built on), presumably where Zeon's elite would reside and observe over the battlefield. A Baoa Qu was built in the opposite L2 point orbit, placing it directly opposite from the Zeon homeland in Side 3. The asteroid provided rear defence, while the Solomon space fortress served as a frontline base. The space fortress served as the Zeon Military Force's general headquarters for their space fleet. It also was used as a mobile weapons production factory. It was the scene of the titanic Battle of A Baoa Qu, one of the greatest battles of the One Year War. Unlike the earlier battle of Solomon, it was a hard-fought victory for the Federation. After the One Year War, A Baoa Qu was kept by the Republic of Zeon following the signing of the Granada Treaty. Later, in June U.C. 0087, the Republic of Zeon would hand it over to the Earth Federation's Titans special force, who would rename it Gate of Zedan. On 18 January U.C. 0088, Axis Zeon, led by Haman Karn, rammed the Gate of Zedan with their own mobile asteroid base Axis, as a part of the negotiations dealt with the AEUG. The event caused the Gate of Zedan to split and shatter, utterly destroying the asteroid. The Titans were shocked by such sudden betrayal, not to mention how much the Titans lost, including the murder of their leaders, Jamitov Hymen and Bask Om. Afterwards, the Gryps 2 colony laser was seized by Axis, and seized again in turn on 6 February, by the AEUG.

A space carrier of the Principality of Zeon. It is one of the largest ships of the One Year War, boasting a size that surpasses not only other Zeon ships, but even the Earth Federation's ships of the time. As a space carrier, it is capable of carrying and maintaining a large number of mobile suits and mobile armors, and has excellent deployment capabilities thanks to its seven catapults. In addition to the bridge, it also has several control stations throughout the hull, giving it a high command capability. While it boasts the firepower of a fortress, its anti-aircraft firepower is low, and it relies on mobile suits and other escort units. Also, due to its massive size, it has low mobility, and was mainly used as a mobile fortress.

The Gwazine-class battleship was developed by the Principality of Zeon to be the flagship and heavy battleship for the various space fleets of the Principality. The Gwazine-class ships are the most powerful space warships fielded during the One Year War, even more powerful than the Federation's Pegasus-class ships, and the second largest to be fielded, second only to the Dolos-class heavy carriers. They are equipped with three massive double-barreled mega particle cannon turrets mounted on their topside. They also have ten smaller double-barreled mega particle cannon turrets, similar to the ones used by the Musai class light cruisers, and finally they have a high number of 155mm double-barreled anti-aircraft machine guns. It has been stated that the Gwazine-class is capable of traveling the distances between the Earth and the asteroid belt, propelled by two primary thrusters and six secondary thrusters. Each of these ships possess hangers large enough to hold up to twenty mobile suits, more than triple what the Federation's Pegasus-class ships can hold. These mobile suits were carried in a large cargo bay underneath the vessel. On the other hand, the Gwazine-class have a few drawbacks. The ships are large and resource-consuming enough that only a handful would be constructed before and during the war. Also, due to their large size and heavy mass, maneuvering them around the battlefield takes time.

The primary cruiser of the Zeon forces, the Musai was developed on the premise of deploying mobile suits. It was propelled by four thermonuclear rocket engines installed at the end of the two nacelle columns extending to the lower left and right of the bridge. Directly below the bridge is a MS deck that can carry four mobile suits, and it is possible to deliver goods directly by conveyor pipe from the Papua-class supply ship using three supply hatches on each side. The lower part of the bow is equipped with an atmospheric entry capsule "Komusai", which is capable of storing supplies, additional personnel, or two mobile suits, adding some logistical flexibility to the ship. The capsule can be launched directly from the Musai and doesn’t require separation prior to ignition, unlike its Federation counterparts. It’s unknown if the Komusai is able to directly reconnect with its mothership upon return. However, any onboard mobile suits can be deployed only after the Komusai has separated, as the capsule's storage hatch is blocked when attached to the Musai. Ships of the class are also capable of launching HLV craft, carried behind the ship between the engines. The cruising range of these ships can be further improved with the optional addition of two large propellant tanks behind the ship. In combat, after fielding its mobile suits, the Musai would engage enemy ships with powerful double-barreled mega particle cannons that could penetrate the armor of any Earth Federation's warships. Other weapons of the ship include a pair of large missile launchers and 10 small missile launchers.

The Chivvay-Class was a ship developed by Zeon to protect convoys and carry out various tasks, and often served as a flagship. It was normally equipped with two triple-barreled mega particle turrets, eighteen twin-barreled anti-aircraft guns, and twelve missile launchers, but it was not designed specifically to carry mobile suits. Despite this, its cargo bays could be easily converted to MS hangers if needed, allowing them to carry as many as eight MS - twice as many as the Musai-class. It was capable of high speeds thanks to its five large thermonuclear rocket engines, with some variations having seven engines. Ships of the class also had two outrigger thrusters near the front, with one on each side of the ship. There were various modified versions of the Chivvay-Class, with some having a third triple-barreled mega particle cannon and additional anti-aircraft guns.

Powered by a high output fusion reactor, the Bigro also has high thrust thanks to a pair of thermonuclear rocket engines, and through the combination of its short body with AMBAC, it is capable of high mobility such as turning 180 degree in 1.3 seconds. The Bigro excels in high-speed hit-and-run tactics, but its high mobility makes it hard for a normal pilot to withstand the high Gs. It is fitted with a Minovsky particle scattering system for jamming enemy units' sensors and is armed with a pair of large claw arms, a mega-particle cannon in the nose, and two 4-tube missile launchers. Later models were armed with additional gatling cannons. Due to Bigro's late entry in the war, only a limited number of this costly machine was constructed, with several units serving as testbeds for next generation mobile armors.

The MS-05B was the late production variant of the Zaku I and the first mobile suit assigned to combat units.[2] An improvement over the MS-05A Zaku I Early Type, the B Type was visually identical to the A Type, but featured an improved cockpit design and better armor material. Like its predecessor, the MS-05B's power transmission pipes were all fixed and contained inside its armor. However, as the B Type saw wider deployment than the A Type, the flaws of this design quickly became apparent: since the power pipes took up most of its internal space, it was very difficult to improve its generator output or swap out parts. The structures of its limbs were also very complex due to the internalized power system. These problems would later be addressed by the MS-06 Zaku II series. Its weapons included a custom machine gun, a 280mm bazooka, and a spike shield. It could also be equipped with the standard weapons used by the MS-06 series, including the 120mm machine gun and the heat hawk.

The MS-05S Zaku I Commander Type is a hastily modified version of the Zaku I that was supposed to be sent to the rear, such as a guidance maneuver battalion or supply unit, to fill the gaps left by the Zaku II, which was produced and deployed later than originally planned. The head is equipped with a blade antenna, and a round shoulder armor is added to the right shoulder. In consideration of cooperation with the Zaku II, leg verniers were added to compensate for the difference in thrust, and a large-capacity backpack was also equipped. Furthermore, its offensive and defensive performance has been improved with various additional equipment.

The MS-06A Zaku II First Mass Production Type was developed after the MS-05B Zaku I was deemed inadequate for the Principality of Zeon's purposes. Overall, the MS-06A Zaku II was very much the same as the MS-05B Zaku I as the Zaku II was merely meant to be an improved version of the Zaku I. To improve combat abilities the Zeonic Company increased the armor to give the mobile suit, and thus the pilot, better protection. The thrusters were also improved to give the Zaku II better mobility than the Zaku I. Finally, the Zaku II received improvements to its sensor package and has a more powerful thermonuclear reactor. To simplify production the A-type Zaku II used the same armaments of the Zaku I, which consisted of the initial Zaku-type machine gun and a front insertion bazooka. At the time of its deployment the Zaku heat hawk was still in development. Because the Principality's brass did not foresee the Zaku being used in close combat situations, and the fact that the nuclear-weapon using C-type was in production, the A-type was never equipped with a heat hawk. With its upgraded performance the MS-06A Zaku II was without equal, which isn't saying much since there were only two production type mobile suits at the time. Still the upper brass of the Zeon military still considered its abilities inadequate.

A redesign of the MS-06A, the MS-06C Zaku II Early Production Type was fitted with spiked armor on its left shoulder and a shield on its right. It was also equipped with a heat hawk for melee combat. In order to protect the pilot from the radiation from the nuclear warheads it fires, it utilized triple-layer composite armor, and the gaps in its armor were filled with a radiation shielding liquid. Because of these measures, its empty weight reached a grand total of 72 tons.

The MS-06F Zaku II was the Principality of Zeon's mainstay mobile suit during the One Year War. Compared to the MS-06C Zaku II Early Production Type, the MS-06F removed the heavy anti-nuclear protections, reducing its armor weight and improving its mobility. It was also refitted with a more powerful generator: the MYFG-M-ES series fusion reactor, jointly developed by "Zeonic" and "M&Y Company". Otherwise, it was not significantly different from its predecessors, the MS-06A and the MS-06C. There existed subtle differences among the F-Type, depending on the time of manufacture and the originating factory. Prior to the introduction of the MS-06S Zaku II Commander Type, MS-06F piloted by squadron leaders were equipped with a head-mounted blade antenna. The MS-06F could run at a speed of 85 km/h, leap 100m into the air with the use of its thrusters, and lift around 80-90t of weight with one hand. Its thrusters had a thrust of 45 tons. Though its punch had a force of 560t, doing so risked severely damaging its manipulators. Instead it more frequently used the spike armor on its left shoulder for shoulder tackle, which had a force of 4,500t.

Developed in response to veteran pilots' request for a high performance unit, the MS-06S Zaku II Commander Type was far more mobile than its predecessor, the MS-06F Zaku II, but was also far more difficult to control. Compared to the F Type, the S Type's vernier nozzles were enlarged, and the output of its main thrusters were increased by 30% while retaining the same size. To make space for the improved thrusters and enlarged propellant tanks, various automatic control systems of the F Type were removed. While this reduced S Type's operability, it also enabled experienced pilots to disable many unnecessary limiters and push the mobile suit to its structural limit. Other changes from the F Type included the S Type's generator being 5% lighter, and its armor composition and structure were improved, improving its overall power-weight ratio. Finally, the S Type were all equipped with a head-mounted multi-blade antenna. Though the antenna itself was identical to those found on the F Type, the structure at its base was different, giving it improved communications and enemy detection capabilities. Despite having many special internal components, the S Type still shared 80-90% of its parts with the F Type, making it easy to resupply and maintain. This also meant that like the F Type, it could easily be modified to operate in space or under gravity.

The MS-06E Zaku Reconnaissance Type, also known as E-Types, mounted specialized cameras and sensor systems. The Zaku II's original mono-eye was replaced with a higher powered, longer ranged mono-eye that actually jutted out from the head. On the shoulders and front pelvic skirt armor were other sensors and cameras. The E-Type also incorporated powerful thrusters in the chest for fast retreats. Along with the upgraded thrusters, it had more propellant storage capacity for long-range missions and a longer operational time. The Zaku Recon Type was usually unarmed, but held in its hands a small "camera gun" for recording its findings. Despite being a detection suit, it could be equipped with standard Zaku armaments such as the 120mm machine gun.

A modified version of the MS-06F Zaku II designed for ground combat, the J-type superficially resembled the F-type, but had many internal differences. It removed any space-use equipment that would have become dead weight under gravity, reduced the oxidizer in the propellant, and adopted an air cooling system, leading to a completely different basic structure around its reactor. Due to the removal of unnecessary equipment, it was lighter compared to the F-type, leading to less power loss under gravity. To account for atmospheric distortion, the light receptor semiconductor unit and measurement software of its monoeye were both updated from the ones used by the F-type, and it featured a more accurate infrared sensor. Its manipulators were coated with soft material for improved sealing, with a new software installed to account for the constant 1G gravity. The F-type's AMBAC system was omitted, and the space used for leg sub-thrusters were used to mount newly designed anti-ground sensors. A pair of hardpoints that also serve as I/O ports were added to its legs. However, the sub-thrusters at the bottom of its feet were untouched, as they could improve mobility when used in conjunction with the main thrusters. The J-type mostly used the same weapons as the F-type. However, due to recoil being less problematic under gravity, it was able to equip various optional equipment, including leg-mounted missile pods, the Magella Top cannon, and cracker grenades.

As the One Year War dragged on, Zeon began to design several different variations of its standard mobile suits to excel in specific mission roles. The Zeonic Company created the first amphibious mobile suit, the MS-06M-1 Zaku Marine Type (also called "Zaku Mariner"), based on the MS-06F Zaku II. The body was identical, except all of the joints were equipped with waterproof seals, and it mounted hydrojet engines on its backpack, arms, and legs as opposed to standard chemical rocket thrusters. The Zaku Marine Type also carried weaponry better adapted for aquatic combat, such as a SUBROC (SUBmarine ROCket) Gun, two 4-tube 240mm rocket pods, and twin vulcans mounted in the head.

The MS-06R-1 Zaku II High Mobility Test Type, is based on the late production variant of the MS-06F Zaku II. Compared to its predecessor, the MS-06R-1 featured a new backpack equipped with two thrusters with 218 tons of thrust each, additional thrusters on its legs, and enlarged integral fuel tanks in the waist. In addition, the MS-06R-1 was also equipped with more powerful weapons, including a 420mm rocket launcher and a 360mm rocket launcher, both of which were prototypes, and the number of externally mounted transmission cables and circuits has increased. In addition, small thrusters have been added, and the waist-mounted integral fuel tanks relocated to the torso and legs. The MS-06R-1 Zaku II High Mobility Test Type is a complete redesign of the MS-06F Zaku II so as to ensure its propellant carrying capacity.

One of the last machines in the Zaku II High Mobility Type series, the MS-06R-2 Zaku II High Mobility Type was Zeonic Company's entry in the competition for the Principality of Zeon's next generation space-use mainstay MS. It was a replacement for the beam weaponry equipped MS-14 Gelgoog which was facing delays in development. The R-2’s exterior is almost identical to the past Zaku II High Mobility Type machines, but it has been greatly altered in various areas, such as a new generator with higher output, a different chest piece, higher propellant capacity, and the use of lighter and better armor material in some sections. Thus, the R-2 has higher performance and is lighter than the R-1 and the R-1A Types. The R-2 was reputed as a “Gelgoog wearing a Zaku’s skin” for its high capabilities. In fact, it used parts meant for the still in development Gelgoog in its construction. A result of this is that its legs’ internal structure has been redesigned. The R-2’s legs are also better armored compared to previous Zaku High Mobility Types, offering better protection against enemies attacks. These added armor also make the silhouette of the R-2’s legs more similar to that of the Gelgoog’s. Like the other Zaku High Mobility Types, the R-2 has propellant tanks in the calfs and thighs to increase the operating time of the legs’ propulsion devices.

The F2 Type was the late production variant of the MS-06F Zaku II. Based on the operation data of its predecessor, the F2's design concept was to revise the Zaku II for anti-mobile suit combat - something that was not accounted for in mobile suit design until the MS-07B Gouf - by reducing its weight and increasing its thruster output. In addition, since the F Type's armor around the cockpit hatch was fragile, the F2 Type featured a redesigned chest armor, which became its most distinctive feature compared to other models of the same series. Since a portion of the F2 Type was produced after the implementation of the United Maintenance Plan, these units share the same unified cockpit design as well as some parts as other second phase production type mobile suits. These units were easier to pilot than existing mobile suits, and were popular among new recruits and cadets.

The Zaku II was one of the second-phase production MS that have been improved by the United Maintenance Plan. The performance of the Zaku II itself has begun to deteriorate due to the appearance of Federation MS and the development of new models by its own forces, so it has been tuned up by feeding back data from new models. In addition, based on the results of the renovation of the MS-06F-2 Zaku II F2 Type, the shape and materials of the armor and the balance of the machine were more thoroughly reviewed, resulting in an appearance that is quite different from the previous Zaku II F-Type. The most significant modification was to the cockpit, which is said to have been so good that even new recruits with insufficient training could handle it. In addition, the apogee motors in various parts of the fuselage and the thrusters in the backpack were increased and made larger, and the total thrust was increased by 70 percent compared to the previous F-Type model. On the other hand, the total amount of propellant had not changed, and the time limit at maximum combat thrust has dropped by half. The armor has also been considerably strengthened and the armament has been redesigned, so it does not lag behind the Federation's GM and has achieved considerable high performance. Rolled out one month before the end of the war, this machine is the final production model of the Zaku in the One Year War, but the number produced was small. It was only used by some units of the Space Fleet (especially the units made up of school soldiers and new recruits).

A high-performance mobile suit produced by the Zeonic Company, the MS-14A Gelgoog is the result of Zeon's attempt to field a mass-production unit that can rival the performance of Earth Federation's RX-78-2 Gundam. It was equipped with a full-sized shield, a twin beam sword (also referred to as a "beam naginata") and a beam rifle, a first for a Zeon mobile suit. The Gelgoog has superior specifications in every aspect to the MS-06F Zaku II and even the MS-09R Rick Dom.

A heavy mobile suit developed by "Zimmad", the MS-09 Dom was a ground combat machine equipped with hovercraft technology. It was fitted with thermonuclear jets and rockets under its feet, allowing it to quickly move across the ground, greatly improving its mobility compared to previous ground-use mobile suits. Thanks to sensors located in front of its feet, it was able to traverse uneven terrain. While in cruising mode, it could hover across the ground using only its thermonuclear jets. The Dom can hover at a maximum speed of 381 km/hr for up to 5 hours. Its primary thrusters adopted the Saturn Engine, a type of thermonuclear engine that used heavy elements such as zinc and lead as propellant, granting it higher thrust than thermonuclear engines that used lighter elements as propellant. For defense, the Dom was heavily protected, adopting a unique "skirt armor" design to protect weak points in the back, such as thrusters. Its cockpit hatch armor, which was its greatest weakness in the front, was also greatly enhanced. However, since the cockpit was entered directly from the front of the Dom, pilots in desert and wetland areas complained that the console panel would become dirty from entering and exiting. Meanwhile, the Dom's head was merged into its chest, a design intended to deflect and ricochet enemy projectiles, as well as lowering the possibility of being hit.

Proposed by Zimmad as one of the competing designs for Zeon's next generation space-use mobile suit in the middle stage of the One Year War, the MS-09R was a variant of the ground-use MS-09 Dom. The MS-09 was chosen as the developmental base due to its good basic design. Its block structure was a major factor that enabled its specifications to be easily changed without modifications to its basic frame. The MS-09R removed the ground-use equipment of its predecessor and replaced them with space-use equipment, increasing its propellant capacity and its vernier thruster output. The thermonuclear jet engines on its feet were replaced with thermonuclear rocket engines. Its backpack thrusters adopted the Saturn Engine, a type of thermonuclear rocket engine that used heavy elements as propellant, granting it higher thrust than those that used lighter elements. Its total spec, including cost and ease of manufacture, surpassed that of the MS-06R-2 Zaku II High Mobility Type, the most advanced mobile suit at the time.

A variant of the Rick Dom that had its generator output and thrusters upgraded at the A Baoa Qu factory, the MS-09RS had its chest-mounted scattering beam cannon, which was originally meant to be used as an energy supply terminal for beam weapons, modified into an energy buffer. This greatly reduced the strain placed on the supply connectors inside its arms, allowing it to be armed with a "beam bazooka", an experimental high-powered beam cannon originally used by mobile armors. Due to issues with the cooling system, the beam bazooka was impossible to mass produce and only assigned to a small number of veteran pilots such as {character}.

Developed late into the One Year War as part of the United Maintenance Plan, the Rick Dom II was an improved model of the MS-09R Rick Dom.[1] Unlike its predecessor, which was based on the ground-use MS-09 Dom, the Rick Dom II was designed from the ground up with space-use in mind, and thus did not take aerodynamics into account. Its armor was redesigned to use a more planar structure, which made it possible to install a more powerful generator and thrusters with higher output. In addition, it was equipped with more vernier thrusters for increased mobility, and a pair of propellant tanks for increased operating time. Technology from the MS-14 Gelgoog was also incorporated into its design. Compared to its predecessor, its production was simplified, and its durability was enhanced. The use of the second stage production type cockpit improved ease of use, lessening the burden placed on the pilot. Despite being specialized for space use, it can also operate within the atmosphere or inside colonies with modifications.

The United Maintenance Plan was designed to rectify the lack of standardization among Zeon's mobile suit parts and production lines. To that end, it was intended to achieve the following: The standardization of hand manipulators, allowing the interchangeable use of handheld weapons (with the exception of beam weapons). The standardization of parts, allowing parts sharing among different models. The standardization of cockpits, shortening the pilot training time needed for switching to a different model. These measures were intended to improve Zeon mobile suits' ease of production and maintenance. They would also contribute to speeding up the development of future mobile suits. The plan began in February, U.C. 0079, as the signing of the Antarctic Treaty signified the beginning of a prolonged war. It was completed four months later, in June, U.C. 0079. Thanks to the implementation of the UMP, Zeon's mobile suit production and maintenance efficiency were significantly increased and the development time of future mobile suits was shortened. In addition, thanks to the adoption of the Second Phase Production Type cockpit, the pilot training time for switching to different mobile suit models was reduced, though amphibious mobile suits adopted a different model of standardized cockpit due to their unique needs for durability and temperature control functions.

The Principality of Zeon had developed the ground use MS-09 Dom, but its nuclear reactor's output was insufficient for powering mega particle cannons/guns. Increasing the reactor output would require better cooling capacity, and the most efficient method was water cooling. Therefore, in November U.C. 0078, MIP and Zimmad received orders to develop amphibious MS which can use seawater for cooling. In addition to the use of mega particle weapons, the amphibious MS can reach its destination by traveling through the sea on its own, allowing it to fight in areas away from Zeon's frontline bases. To reduce water resistance, the Gogg's head became a rounded streamline shape, the MS' equipment was internalized, and the limbs can be retracted when cruising underwater. The Gogg has long operating time in water, and relies on thermonuclear hydrojet engines that draw in water, then heat them with the high heat of the reactor to create thrust. When operating on land, cooling water is stored in internal ballast tank, and the mobile suit's operating time is limited to 1–2 hours. This shortened operating time on land is due to reactor cooling limitations. The Gogg is not an agile machine due to its weight, but its pressure-resistant design provides sufficient defense in close combat.

Following the Zimmad Company's MSM-03 Gogg, the Zeonic Company produced their own amphibious mobile suit for the Principality of Zeon, the MSM-04 Acguy. The Acguy used many of the same parts and components as the MS-06F Zaku II, including two of the Minovsky Ultracompact Fusion Reactors used by the latter. Even with the twin reactors, the Acguy left only a trace heat signature, making it effective for stealth and infiltration operations. It is also one of the tallest amphibious mobile suit used by the Zeon during the war. The Acguy's weapons consisted of four 105mm vulcan guns mounted in its unusually large head. In its right forearm was a mega particle gun, but in some units, this was replaced by a vulcan gun. The right forearm also had extendable claws known as Iron Nail (along with an extendable arm to increase striking distance) for striking the Earth Federation's mobile suits and property. In the left forearm was a six-tube missile launcher. Some models also had missile launchers in the right forearm, replacing the mega particle cannon and claws.

he MSM-07S Z'Gok Commander Type is an improved, higher performance model of the Z'Gok, it has higher reactor output, better maneuverability and a change in armor materials. It eventually became the standard Z'Gok model. The Zeon ace pilot, {character}, better known as the "Red Comet", piloted a Z'Gok Commander Type in his personal red color scheme during the assault on the Earth Federation's Jaburo General HQ on November 30, U.C. 0079.

As Zeon prepared for its massive invasion of the Earth Federation Forces' underground military headquarters in Jaburo, located along the Amazon River in South America, the Zeon military engineers at California Base began developing several special operation mobile suits to aid in the assault. The Juaggu was one such machine, created based on the MSM-04 Acguy, its role is that of a rearguard and a mid-range fire support unit for its fellow special operation mobile suits. The biggest feature of the Juaggu is its elliptical head, which has a movable exhaust heat duct similar to an elephant's trunk. Like the Acguy, the Juaggu is an amphibious mobile suit and can travel underwater using the aquatic propulsion systems in its backpack and feet. The mobile suit also has heavy armor to defend against ballistic attacks during the assault on Jaburo. Its armament consisted of a pair of arm-mounted triple rocket launchers and four mega particle cannons in its torso. When required, the triple rocket launchers can be replaced by the standard 5-finger manipulators.

As Zeon prepared for its massive invasion of the Earth Federation Force's underground military headquarters of Jaburo, the Zeon military engineers stationed at California Base began developing several specialized mobile suits to aid in the assault. One of these designs was the Agguguy, an amphibious mobile suit based on the MSM-04 Acguy. The Agguguy was heavily armored, yet still surprisingly agile and quick. The Agguguy was designed primarily for close combat with two 20mm vulcan guns in its head, as well as a pair of spinning whip-like heat rods built into each hand that could be used to grapple with enemies, or electrocute and slice through foes. The Agguguy's heat rod hands can also be removed and replaced with razor-sharp claws similar to those of the MSM-07 Z'Gok.

The MSM-08 Zogok is a prototype amphibious mobile suit with improved melee capabilities that was developed during the One Year War. A variant of the MSM-07 Z'Gok, the Zogok was one of the special operations "Ag series" for Zeon's invasion of Jaburo. It was meant to work alongside the other mobile suits of the series, such as the MSM-04G Juaggu, and its role was that of the vanguard. Unlike Z'Gok, Zogok is not equipped with any firearms like mega particle cannons; instead, it has unique melee weaponry such as arm punches using its extendable arms, launchable boomerang cutters from the top of its head, etc. These weapons were also selected to minimize the emission of light and heat, lowering the chances of being detected during the infiltration into the heavily guarded Jaburo. Although an amphibious unit, the Zogok's combat capabilities are primarily meant for ground battles. The Zogok's aquatic ability is limited to travelling underwater using the propulsion units in the sole of its feet. Its backpack has no function underwater and was designed with maximum ground performance in mind. Like many other of Zeon's amphibious mobile suits, the Zogok has no independent head unit to reduce underwater resistance. The functions of such a head unit were integrated into the chest. The large mono-eye camera in the center of the chest has a wide range of motion, and the transparent cover protecting it has fairly high durability.

he MS-07B Gouf is designed specifically for Earth-based, close-quarter MS combat. It featured much-improved mobility with a powerful backpack and leg-mounted thrusters for jet-assisted jumps based on the YMS-08A High Mobility Test Type. For armaments, it has the 5-barrel 75mm machine gun in its left hand and a heat rod, which could be used as a superheated slicing weapon or as a grappling weapon with a powerful electric shock effect. It also had a powerful heat sword stored within a shield, and could also use the standard Zaku II weapons, such as the 120mm machine gun or the 280mm bazooka. The Gouf outclassed the MS-06 Zaku II in terms of speed, power output, and melee combat ability, but its overall performance was not great enough to be justified by its increased cost. The Gouf's production was cut short by the development of a more cost efficient unit, the more powerful and nimble MS-09B Dom. Despite its very short production run, several variations were produced in limited numbers and it was still deployed across the world alongside Zakus and Doms. One customized unit was piloted by Visch Donahue, which had the original 5-fingered machine gun left hand replaced by a normal manipulator hand, in its place a 3-barrel 35mm machine gun was mounted on the left forearm.

During the deployment of the Gouf, its limited combat versatility became evident with its design concept of emphasis on hand-to-hand combat. Numerous disadvantages surfaced during operation on the battlefield, such as lack of flexibility due to the Gouf's fixed armament. The Gouf would be completely redesigned as the MS-07B-3, which was an improvement over the original. The Gouf Custom was designed with improved close quarters shooting and detachable weapons. It was designed primarily for ace pilots preferring a lighter mobile suit that could leap and jump as opposed to the heavy, yet effective MS-09B Dom. The Gouf Custom featured multiple changes to the MS-07B, including the elimination of the awkward five finger 75mm machine guns, replacing it with a normal manipulator and a wrist mounted 3-barrel 35mm Machine gun. The coil-like heat rod is replaced with a magnetic grappler wire that connects and disables an enemy with an electric charge rather than damaging them. The grappler wire could also be used as a repelling line that could slow or even halt the descent of a falling Gouf in the right conditions. The shield of the Gouf was modified so that it not only stored the Gouf's heat sword but is also capable of carrying a 75mm gatling gun, greatly enhancing the mobile suit's fire power.

The Dom Funf was independently developed by Zimmad as an improved model of the Dom following the implementation of the United Maintenance Plan. Due to standardization and compartmentalization, it can be easily modified into different variations.

Following the successful testing of the Prototype Dom at California Base, Zeon began to mass-produce the MS-09 Dom. The design however had a flaw: it was especially difficult to maintain in certain environments, specifically in Earth's high temperature tropical zones. To attempt to come up with a solution, Zimmad Company converted one of the two Prototype Doms into the Dom Tropical Test Type. The Dom Tropical Test Type featured a heat dissipation pipe on the head to enhance its heat dissipation capacity, the propulsion engine on the back is also modified for tropical battles, and it is equipped with a large-capacity cooling system. In addition, an antenna for short-range communication has been added to the head. These features helped the mobile suit maintain better combat efficiency in tropical climates.

A redesigned version of the MS-09F Dom Funf, the Dom Tropen was developed to operate exclusively in tropical regions on Earth, in particular the desert areas. Introduced by the Zeon military late in the One Year War, it also incorporated data taken from the MS-09 Dom and YMS-09D Dom Tropical Test Type. Compared to previous Doms, it is a machine that takes into consideration aerodynamic shape and maintainability. The basic structure of the head unit is closer to that of the MS-09R-2 Rick Dom II than to that of the Dom, and the top of the head is equipped with a sub-sensor. The mobile suit featured modified intake filters for its leg-mounted thermonuclear jet engines, allowing it to retain its high ground hovering speeds without fear of sand ruining the engines. In addition to dustproof air filters and enhanced cooling devices in various parts of its body for desert and hot weather specifications, the Dom Tropen has specialized block-shaped armor designed to facilitate the removal of sand that enters the interior. Armament compatibility has also been thoroughly improved, making it possible to equip anything other than beam weapons.

Another variant of the MS-09B Dom, It is the final production model of the Dom series. It featured head mounted vulcan guns and external propellant tanks, extending its hover ability. In addition, the rear thermonuclear jet propulsion unit features dust filters and is equipped with a back-mounted antenna to increase communication capabilities. In addition to the heat saber used by most Doms models, the Dwadge can also used a heat tomahawk. The Dwadge also used a slightly larger (380mm) version of the giant bazooka which uses shaped charge ammunition.

During the One Year War, the battlefield shifted from space to Earth after the signing of the Antarctic Treaty. Because of Earth's many different terrains and environments, the Principality of Zeon had to adjust their mass production MS-06J Zaku II Ground Type model to be more suitable in the varying climates. Developed in the captured Earth Federation California Base, the MS-06D Zaku Desert Type, also known as the D-Type, was designed for Earth's desert and tropical regions. Early test units used a double antennae, but when Zeon finalized the mobile suit for mass production, they dropped it down to a single antenna. They also repainted the Zakus to a more sand-like color. The Zaku Desert Type featured several new features for its adaptation to the new climates. The biggest change was the replacement of the Zaku II's standard thruster jetpack with a heat-dissipating radiator backpack. The D-Type was thus fitted with jet thrusters in the legs and skirt armor so that it had a small boost in mobility.

A mobile armor designed for maximized offensive power, the Big Zam was considered the largest and most powerful tactical weapon during the One Year War. It was armed with a wide array of weapons, including a large mega particle cannon in the front of its torso, capable of sinking a Magellan-class battleship with a single shot. Across its torso was an array of anti-air mega particle cannons, which were used to prevent mobile suits from approaching. The claws on its legs could be fired as missiles. For protection, it was equipped with a barrier that nullified beam weapons. In order to power all of its beam weapons at the same time, the Big Zam was equipped with four large fusion reactors, each with a power output of 35,000 kilowatt. Due to issues with cooling, it was only able to operate at full combat capability for less than 20 minutes. Its cockpit block, located in the upper torso, housed three pilot seats: a pilot, a radar operator, and a gunner; though it could be operated by a single pilot with the assistance of computers.

Featuring a high-powered generator, various thrusters to aid mobility, a large pointed oval-shaped shield, a Beam Rifle, and a Beam Naginata, the MS-14S Gelgoog Commander Type rivals the capabilities of the Earth Federation's RX-78-2 Gundam. In fact, compared to the Gundam, the Gelgoog Commander Type is slightly faster, more mobile and possesses a more powerful generator and beam weapon selection; this was proven by {character} during his first sortie in his personal unit against Amuro Ray's Gundam during the One Year War. On the other hand, it has thinner and less durable armor than the Gundam (which is built with Luna Titanium Alloy), and the lack of built-in weapons makes the Gelgoog easier to disarm.

A variation of the Gelgoog, which replaced the Zaku II as the mainstay mobile suit of the Principality of Zeon for the final battle. As ace pilots were prioritized in the assignment of the Gelgoogs and their machines were modified to fit their piloting style, a number of functional-specific Gelgoog variants were created in a short period of time. One of these variants is this B-type, which is equipped with an easy to retrofit, modular booster pack on its back for increased speed. This modification can be applied to both the prototype and standard mass-production Gelgoogs, boosting their thrust by around 30%. With its explosive acceleration capabilities, the Gelgoog High Mobility Type excels in anti-ship combat using hit-and-run tactics.

A modified version of the Gelgoog for local warfare. It was designed for operation in the desert, with dustproofing measures applied to various parts, and to deal with heat problems, the cooling system was strengthened, and the built-in power pipes were exposed to the outside, to thoroughly dissipate heat and cool the machine, making it possible to withstand long hours of operation in the desert. To ensure mobility under gravity, thrusters were added to the legs and a backpack was also installed. The arm-mounted jet propulsion systems, which are redundant for sub-gravity combat, have been removed, and the left forearm is equipped with the distinctive Armed Buster, a collapsible projectile weapon. Additionally, the backpack is equipped with a scope for observing the surroundings from within the trenches or in the sand, making it an machine that excels in guerrilla warfare and covert operations.

A Gelgoog modified for combat on Earth. Unlike the original prototype it is equipped with a backpack for use under Earth's gravity. It has also undergone modifications such as dustproofing on its joints, the removal of the spare generators on its arms, and the installation of a grenade launcher and gatling as internal weapons. It is also referred to as the "G Type" and features the same handheld armaments as the standard production model Gelgoog. One customized unit was operated by Visch Donahue, it was painted in a green color scheme and had its backpack removed therefore having its exterior resemble the pre-production type Gelgoog.

The MS-14GD Gelgoog G is a reconfiguration of the MS-14G Gelgoog Ground Type into a desert combat mobile suit. It is equipped with the same heat-dissipating radiator backpack as the MS-06D Zaku Desert Type. Design changes were made due to the falling parts supply and production capabilities at the California Base because of the worsening war situation. Changes included removal of the leg thrusters and omitting hover capabilities, which improved mobility performance. It carries a lighter shield and a desert-use beam rifle which featured a barrel cooling system.

When the plans for the new MS-14 (formerly MS-11) Gelgoog were completed, twenty-five prototypes, under the designation YMS-14S (the Y in YMS-14S means it is a prototype Mobile Suit) were produced; twenty-four of the machines were given to the Chimera Corps. Of these twenty-four units, nine were configured into the MS-14B Gelgoog High Mobility Type while the rest were outfitted as Gelgoog Cannons. The Gelgoog Cannon is equipped with a specialized head unit and mounts a powerful beam cannon on a modified B-type backpack, and even with it, the suit's reactor is still powerful enough to support other weapons systems. This meant the Gelgoog Cannon could carry beam rifles and bazookas, or even swap out the forearm jet engines to mount other optional equipment. As the Gelgoog Cannon made use of the B-type's powerful backpack, it had enough thrust to keep itself maneuverable despite the added weaponry. The suit soon proved itself a capable fire-support and anti-fleet unit.

A variation of the MS-14 Gelgoog, the MS-14JG was specialized for precision firing mission, and was also known as "Gelgoog Sniper Type". It was designed with the United Maintenance Plan (UMP) in mind, greatly increasing its specifications and ease of piloting, as well as simplifying its manufacturing process and improving the interchangeability of its parts with other models. The Gelgoog Jäger was equipped with a total of 24 posture control sub-thrusters in addition to the main thrusters, significantly improving its mobility in space. Due to its nature as a sniper unit, its monoeye has a larger field of vision than standard units. In addition, since it was designed as a commander unit, it was equipped with a head-mounted blade antenna by default for enhanced communications. Similarly, its backpack had another antenna and a laser communication unit. The Gelgoog Jäger's primary weapon was a large-sized beam machine gun, which could either fire pulsed beam pellets or a single-shot long-range beam. It was able to use this weapon thanks to a tuned up, new model generator. The beam machine gun's low rate of beam deterioration, combined with its exceptionally accurate scope and the Jäger's latest fire control hardware and software, granted it unparalleled firing accuracy.

Although the MSM-03 Gogg was one of the first true amphibious mobile suits, it was handicapped by several problems including being under-powered, limited armament, and poor performance on land. To address these shortcomings, the Hygogg was developed. Introduced at the end of the One Year War, this machine was designed from scratch and retained only its predecessor's basic concepts. The result was a smaller, lighter, compact, and more powerful machine equipped with an improved generator and better weaponry. Its agility and mobility in water and on land were also enhanced. Additionally, production costs were reduced due to the implementation of standardized parts, including the cockpit, derived from the United Maintenance Plan, which greatly enhanced repairs and servicing. The Hygogg's shoulder armor can flip down and its arms can be retracted to assume a streamlined form for improved underwater cruising, while an optional jet pack can be mounted on the back for short aerial mobility. Weapon wise, a pair of 120mm machine cannons are mounted in the waist, four torpedo launchers in the head, vice claws in the forearm, and its primary weapon is a pair of hand-mounted beam cannons similar to the Z'Gok series, allowing for better ranged attack.

The YMS-15 Gyan was developed by Zimmad in the late stages of the One Year War for the Principality of Zeon's second phase mainstay mobile suit development project. It was designed with exceptional close combat ability in anticipation of melee combat against the Earth Federation Forces' mobile suits. However, its focus on close combat resulted in lower versatility. Ultimately, Zeonic's MS-14 Gelgoog was selected as the second phase mainstay mobile suit due to its superior general performance and versatility, though the Gyan's basic performance was said to be superior to the Gelgoog. Though the Gyan's reactor output was not sufficient for a beam rifle, it was more than enough to power its primary weapon, a custom beam saber. Its only other weapon was the missile shield, an equipment that combined offensive and defensive capabilities. Thanks to its use of the fluid pulse accelerator, as well as its arms and hands being tuned specifically for close combat, the Gyan's responsiveness and range of motion were extremely high among One Year War-era mobile suits. A Gyan was customized for use by Colonel M'Quve of the Mobile Assault Force. The appearance of the Gyan, with its silver armor and Pickelhaube helmet design, had a strong resemblance to a medieval armored knight. This was further emphasized by M'Quve's fighting style, which was heavily based on fencing.

The "E" in the MS-18E Kämpfer's model number was an abbreviation for the German word "Einhauen," which translates to "to smash sth. in." "to smash in" summed up the suit's role as a fast assault unit that was meant to strike quickly, cause massive damage with its varied weapons loadout, and make a fast escape. The Kämpfer was a very focused design, never intended to work outside of its role. Within this role it was an exceptional unit, rivaling the Federation's RX series in firepower and speed. It was equipped with numerous thrusters and verniers to achieve high maneuverability. Conversely, the large number of thrusters resulted in higher fuel consumption rate, limiting its operational time. The Kämpfer's design opted for minimal armor, even removing the hip-mounted skirt armor found on most mobile suits. The choice of conventional shell-based weapons rather than beam weapons was made to reduce the drain on its reactor and resultant drop in speed. Weapon racks were designed to be ejected from the unit as they were expended, minimizing dead weight. The Kämpfer was intended to be operated by special forces, and was built to be easily disassembled and reassembled in blocks, aiding in its infiltration behind enemy lines.

The Z'Gok E was an experimental improved version of the MSM-07 Z'Gok. Besides improved beam cannons in its arm, allowing for rapid-fire, the original Z'Gok's head-mounted missile launchers were also replaced with torpedo launchers for additional firepower when operating underwater. To allow for better cruising range underwater, the suit's main propulsion systems were relocated from the back to the legs to create a more streamlined body shape. Its limbs were also designed to be retractable for the same reason. The thrusters built into its back were meant for jumping and various ground based movements, and greatly boost the suit's mobility on land. The Z'Gok E used a standardized cockpit with the introduction of the United Maintenance Plan, and was powered by an improved generator which gave the suit ample performance.

A retrofitted version of the MS-05 Zaku I, the MS-05L Zaku I Sniper Type's primary weapon was a beam sniper rifle, which was powered by a backpack-mounted sub-generator. Its head unit was fitted with the same type of composite monoeye as the MS-06E Zaku Reconnaissance Type, granting it the necessary sensor range for long-range sniping. It was also equipped with a pair of head-mounted Vulcan guns for defense. A foldable knee pad was installed in its right knee, which can deploy to stabilize the mobile suit during sniping missions. Essentially, the Zaku I Sniper Type was a self-propelled long-range mega particle cannon turret.

The Gundam was incredibly advanced for its time. Built from lightweight Luna Titanium Alloy, its frame was both lighter than that of Zeon's mass-produced mobile suits and much sturdier, able to shrug off a MS-06 Zaku II's machine gun fire with little to no damage. Its offensive power was above and beyond that of the Zakus. The Gundam would engage in most battles with its beam rifle, making it the first mobile suit to have firepower equivalent to a battleship's beam cannons. In addition, it made use of two beam sabers, blades of extremely hot plasma which could cut through any metal with ease. Those beam sabers could be extended into a spear-like beam javelin, which could be used to stab into an enemy from a longer distance. The Gundam also used more conventional weaponry; it could launch rockets with a "Hyper Bazooka", the Federation's answer to the bazookas used by Zeon's Zakus; in addition, its head was outfitted with a pair of small vulcan guns, as a way of attacking light-armored aircraft and vehicles without wasting ammo or energy from its more powerful armaments. Lastly, it wielded a shield which would offer it a defense against enemy attacks that not even its Luna Titanium body could withstand without damage. Gundam pilot, Amuro Ray, would make use of the shield as a decoy in many battles, taking advantage of its size to fool the enemy into thinking he was charging at them, then attacking the enemy through the shield.

The RGM-79 GM (aka GM, pronounced Jim) is a mass-produced Federation mobile suit based on the RX-78-2 Gundam. Its basic frame is easily adaptable to modifications into mission specific GM models, and has a fairly high level of mobility, for the time, both on Earth and in space. It has a maximum acceleration of 0.94 Gs in space, which is better than the Gundam's and roughly twice of the Zaku's. The armor of the GM uses Titanium Alloy. Although titanium alloy is less durable than Luna Titanium, it is also slightly lighter which reduces the GM's overall mass. The GM was primarily armed with a beam spray gun, a less powerful version of the Gundam's beam rifle but could still destroy MS in one shot. Early in production, the beam spray gun had yet to be mass-produced so most GMs were equipped with various machine guns. These machine guns continued to be used by the GMs later, and the machine could also use the Gundam's beam rifle when required. It could also use a mass production version of the Gundam's Hyper Bazooka for heavier firepower. For close combat, the GM has a beam saber, and a shield similar to the one used by the Gundam. Commander units sometimes featured a second beam saber. Lastly, the GM has a pair of head-mounted 60mm vulcan guns for intercepting missiles, small vehicles or to stop enemy MS from closing in.

An amphibious mobile suit developed by the Earth Federation Forces during the One Year War to oppose the Principality of Zeon's amphibious mobile suits, the RAG-79 Aqua GM was based on the RGM-79 GM and incorporated data from the RGM-79U GM Sloep. The Aqua GM has hydrojet units equipped in its backpack, shoulders and legs for underwater propulsion, with nozzles for the hydrojet units also present on the soles of the feet. The output of these hydrojet units were superior to Zeon's MSM-07 Z'Gok, but lower than that of the MSM-03 Gogg's. The Aqua GM was also fitted with weaponry more suited for underwater combat, such as torpedo pods, missile launchers, special beam picks, etc. due to regular beam weaponry's reduced effectiveness in water. Its head was also reinforced to better withstand the underwater pressure. Unfortunately, the Aqua GM's rushed development led to it being an unbalanced and unwieldy machine. Furthermore, the use of the general-purpose GM as the base unit meant that the Aqua GM was unable to fully adapt to the very unique underwater environment. As a result, the Aqua GM's combat performance failed to match that of Zeon's amphibious mobile suits.

The advent of the Principality of Zeon's amphibious mobile suit was a far greater than the Federation Army could have anticipated. Because the Federation did not have an effective countermeasure against this, they decided to develop optional equipment that would take advantage of the versatility of the RGM-79 GM. It was equipped with an underwater backpack and an auxiliary ballast tank on each of the legs, allowing underwater activities. There was no difference in the appearance of the GM as the base, but some were subjected to pressure-resistant processing. To dive underwater, seawater is injected into the ballast tanks. However, this machine has a slight buoyancy even when the ballast tanks are full, so it was designed to dive using the "dynamical dive method," which uses thrust and a diving rudder. Since the GM didn't have built-in underwater sensors, it was equipped with a periscope-style sensor pod and a handheld sonar gun instead.

Originally, it was planned for the RX-77-2 Guncannon to be mass-produced with a few tweaks to its design, but in consideration of the wartime situation, the design was changed to make use of the existing production line of the RGM-79 GM. Following a series of trial and error, the GM Cannon was created as a simplified mass production model of the Guncannon. A medium-range support mobile suit, the GM Cannon shares 60% of its parts with the GM, and has a high initial velocity cannon of the same caliber as the Guncannon's attached to its notched right shoulder. Its legs are fitted with removable left and right split type increased armor to maintain the mobile suit's balance when firing the cannon during ground combat.

The RX-77-2 Guncannon was a mobile suit used by the Earth Federation Forces. A middle-range support mobile suit developed simultaneously with the RX-78 Gundam and the RX-75 Guntank as part of Operation V. Due to its role as an artillery support unit, the Guncannon's design prioritized durability over mobility, and it was not equipped with any melee weapons. However, its armor was particularly heavy, capable of surviving a direct hit from a bazooka. Similar to the Guntank, the Guncannon's main weapons were a pair of shell-firing cannons, chosen for their reliability over beam weapons. These cannons could be optionally swapped out for a pair of spray missile launchers. The Guncannon's generator output allowed it to equip a beam rifle. It was also equipped with a pair of head-mounted vulcan guns and hand grenades for attacking enemy strongholds. The fire control of the Guncannon was primarily handled by the sensor array and coprocessor system in the head. However, the shoulder-mounted cannons incorporated data from the circular sensor on its crotch, and were capable of autonomously tracking and locking onto targets to a certain extent, independent of the pilot's control. While the Guncannon's mobility was adversely affected by its weight, the backpack thrusters have sufficient thrust to enable jumping maneuvers under gravity for a short period of time.

The RX-75 Guntank was the first prototype Earth Federation Forces mobile suit developed by Operation V. However, it was said to be closer to a tank rather than a mobile suit. A number of companies such as Takim and Hervic participated in its development. The Guntank had the torso and arms of a mobile suit, but possessed caterpillar treads for legs. Initially, it was designed to be piloted by a crew of two, with a gunner in the canopy-style cockpit on the head and a driver in another cockpit in the torso. However, it was later changed to be controlled by a single pilot in the canopy-style cockpit. Its reactor is a hybrid type of nuclear reactors and gas turbines, and its output is insufficient for powering beam weapons. The Guntank's main weapons are twin 120mm cannons, which are effective at long and medium ranges. Its arms have four-barrel missile launchers instead of hands, and they provided good cover fire against enemy tanks and aircraft, but are less effective against enemy mobile suits. A major flaw of the Guntank is its inability to turn its torso, making it difficult to aim the cannons at moving targets, as the Guntank must reposition itself. Another major flaw is that its design was primarily for ground combat, resulting in it having poor maneuverability in space.

the Minovsky Physics Society was formed in U.C.0045 at the space colony Side 3. Their research was devoted to the development of a nuclear fusion reactor. By the year U.C.0047, development of the Minovsky-Ionesco reactor began. This reactor, although designed by Dr. T.Y. Minovsky in his earlier days when he was serving the Earth Federation, was still a piece of black box technology and rendered him a heretic in the classical physics community (where classical in the Universal Century includes the modern physics of today). This is the main reason for his termination of service in the Earth Federation and taking residence in Side 3 prior to the One Year War. However, seeing the horror of the Zabi family's militaristic regime, Minovsky defected back and offered his expertise to the Federation. However, his inventions were applied very differently by the Earth Federation.

The Minovsky-Ionesco reactor was named after its fictional inventor. This reactor was "radical" due to the fact that it was the first "clean" nuclear reactor, emitting zero neutron radiation. The nuclear equation was: 2 3 H e + 1 2 H → 2 4 H e + p (energy released: 18.35 MeV) The reactant used a rare isotope of helium known as helium-3 (i.e., 2 protons and 1 neutron in the nucleus). A helium-3 atom is fused with a deuterium atom (heavy hydrogen) to form the stable helium-4 and a single proton. Since the proton is positively charged, it can easily be trapped within a magnetic field. The main practical problem with this reaction is that helium-3 is extremely rare; there are few deposits on Earth, mainly found in uranium mines, and these are mostly depleted. The fusion reactors rely on a constant supply of helium-3 imported from the outer solar system planet Jupiter, thus necessitating the beginning of the Jupiter Energy Fleet. The JEF would travel from Earth to Jupiter, which has a high level of helium-3 in its atmosphere, and then come back to Earth with the gas fuel. It should be noted that in real physics, helium-3-deuterium fusion produces neutrons due to inevitable deuterium-deuterium reactions. Also, significant quantities of helium-3 were recently discovered on the moon, although there is certainly much more on Jupiter.

the Minovsky Physics Society, while working on the reactor, encountered a strange electromagnetic wave effect in U.C.0065 within the Minovsky-Ionesco reactor that could not be explained by conventional physics. Within the next few years, they identified the cause: a new elementary particle generated by the helium-3 reaction on the inner wall of the reactor, which was named the Minovsky particle or "M" particle. The Minovsky particle has near-zero rest mass - though, like any particle, its mass increases to reflect its potential or kinetic energy - and can carry either a positive or negative electrical charge. When scattered in open space or in the air, the repulsive forces between charged Minovsky particles cause them to spontaneously align into a regular cubic lattice structure called an I-field. The main use of the Minovsky particle was in combat and communication. When the Minovsky particle is spread in large numbers in the open air or in open space, the particles disrupt low-frequency electromagnetic radiation, such as microwaves and radio waves. The Minovsky particle also interferes with the operations of electronic circuitry and destroys unprotected circuits due to the particles' high electrical charge which act like a continuous electromagnetic pulse on metal objects. Because of the way Minovsky particles react with other types of radiation, radar systems and long-range wireless communication systems become useless, infra-red signals are defracted and their accuracy decreases, and visible light is fogged. This became known as the "Minovsky Effect".

The Universal Century (commonly abbreviated as "UC" or "U.C.") is the primary timeline of the Gundam anime metaseries. {character} is part of this timeline.

The disruption of electromagnetic radiation is due to the small lattice of the I-field creating fringes that long wavelengths cannot penetrate, and that diffract wavelengths that have similar distance with the fringes. This diffraction and polarization process disrupts the electromagnetic waves. Notice in real life there is a similar experimental particle that could do the same thing in few thousandth of a second, which is still not practical but proves the theory to be correct. A second use of the I-field (and Minovsky particles in general) was the repulsion of charged plasma and chargeless mega-particles from an I-field surface, which was of use both in power generation and armament technology. If controlled, the particles can form fringes of different widths and further interfere with electromagnetic waves of shorter wavelengths. This provides the basis for the miniaturizing of fusion reactors installed in mobile suits since a controlled I-field can block the infra-red waves. This reduces the heat from the thermonuclear reaction and reduces the need for coolant and shielding for the fusion reactors. Without such a field, a pilot would be boiled alive in a few nanoseconds and the suit would burst into superheated gasses, thus explaining many of the series' casualties when the reactor of a mobile suit is pierced with a beam weapon powerful enough to disperse this I-field.

In UC 0071, Zeon researchers created the Minovsky ultracompact fusion reactor . Instead of the conventional magnetic field, this improved version of the Minovsky-Ionesco reactor used an I-field to confine and compress the reactor fuel, triggering a fusion reaction. The Minovsky particles produced as a byproduct of the helium-3 fusion reaction were recycled to keep that reaction going. The Minovsky particles that form the I-field lattice also helped catalyze the fusion reaction, in a process similar to the muon-catalyzed fusion investigated by real-world scientists during the 1950s. This super-efficient design was only a fifth as large as an equivalently powerful Minovsky-Ionesco reactor, allowing the reactor to be mounted within the mobile suit instead of an external backpack. For this reason, it was adopted for use on mobile suits as the standard power plant. Furthermore, Minovsky also developed the Fluid Pulse system, which utlized the Minovsky Particles to drive the Mobile Suit's system, which allows active attitude control possible. This unlimited source of electricity supplies the power needed to run an MS' avionics and life support systems, as well as the actuators and motors control the MS' joints.

During the One Year War, the researchers of the Flanagan Institute discover that Newtypes emit powerful thoughtwaves - similar to regular brainwaves, but not electrical in nature - which they call psycho-waves. The Flanagan Institute goes on to develop a mind-machine interface called the psycommu (psycho-communicator) system, which receives these thoughtwaves and translates them into computer commands. Using this interface a Newtype pilot can direct remote weapons, and operate huge mobile armors, by thought alone.

In the Universal Century, space colonies are giant artificial structures in space, designed to house large-scale human habitation. The Earth Federation was responsible for the construction of all the inhabited space colonies within the Earth Sphere, and around 10 billion people were space colony residents by the outbreak of the One Year War. Nearly all colonies in the Universal Century (except some rare older colonies such as "Moon Moon") are O'Neill "Island 3" type cylindrical colonies. Most of these colony cylinders are the "open type" with three giant mirror panels that reflect sunlight into the colony via transparent "window" walls, while the colonies at Side 3 are "closed type" cylinders without any windows. Every colony also has its own satellite modules for food production, energy generation and industrial operations. Space colonies are placed at the five gravitationally stable regions in the Earth-Moon system, known as Lagrangian points. In most cases, each Lagrangian point can accommodate a significant number of space colonies, and the closely clustered group of neighboring colonies are known collectively as a "Side". It is possible to have two Sides occupying the same Lagrangian point in a binary system-like orbit to one another, as in the case of Lagrangian points 4 and 5.

The Principality of Zeon, also referred to as the "Duchy of Zeon" and "Zeon Dukedom", is a nation that was in control of the colonies of Side 3 and fought against the Earth Federation during the One Year War. In U.C.0053, Zeon Zum Deikun was appointed Prime Minister of Side 3. On September 14, U.C.0058, Side 3 declared independence and established the Republic of Zeon. In U.C.0068, Deikun suddenly died of a heart attack during a parliamentary speech. When Degwin Sodo Zabi took control, he wiped out the opposition and abolished the Republic on August 15, 0069, and declared a transition to a monarchy called the "Principality of Zeon". The Zabi family, having gained power, aimed for independence from the Federation government by force. On January, U.C. 0079, the Zeon War of Independence (One Year War) began. With a lack of command and control, the remaining Zeon fleet went into a panic. Split as to what to do, several ships gathered as many as possible before fleeing the battlefield, while others remained to fight to the last man, each believing that it was what their commanders wanted. With the fall of A Baou Qu, the remaining government of the Principality of Zeon surrendered to the Earth Federation. The war was brought to an end with the signing of the Granada Treaty on January 1, UC 0080. With the Zabi family's reign ended, the remaining citizens of the Principality of Zeon entered negotiations with the Earth Federation. It was replaced by the Republic of Zeon, the colonies of Side 3 formed their nation subject to Federation inspections and review. Maintaining a small defense force comprised of ships and mobile suits from the Principality of Zeon, the Republic of Zeon has taken on a more peaceful relationship with the Earth Federation. Loyalists to the Principality of Zeon and the Zabi family did continue, however, as those that escaped capture or death at the Battle of A Baoa Qu either hid within the Earth Sphere or fled to other regions, including the asteroid Axis and Mars. These loyalists later formed their movements based upon the principals of the Principality of Zeon, with one Neo Zeon movement being led by the daughter of Admiral Maharaja Karn, Haman Karn. She used Dozle Zabi's daughter Mineva Lao Zabi as a figurehead and rallying point for the movement.

The Earth Federation was formed in the pre-Universal Century (i.e. the late 21st Century A.D.), when overpopulation began causing famines, outbreaks of disease, and wars over living space, food, and resources. The inauguration of the Earth Federation's charter marked the beginning of the Universal Century calendar system with the year 0001 U.C., but this event was marred by a terrorist attack on Laplace, a space station that had been built as the official residence of the Earth Federation Prime Minister. Laplace was destroyed, and the first elected prime minister, Ricardo Marcenas, perished. In order to relieve Earth of the burden and allow it to heal, the Earth Federation announced the Space Colonization Plan. The Earth Federation began the construction of orbital habitats, based on the designs and research of Gerard K. O'Neill, and located in the Earth-Lunar Lagrangian Points. The colonies, called Bunches (possibly due to the ballistic pairing of the colony cylinders) were then organized into administrative sectors called Sides. While most of the human population was forced to relocate to the colonies as part of the Space Colonization Plan, the wealthy and influential members were able to remain on Earth. This gave rise to the image of the Earth Federation as "Earth-Born Elite", living comfortably on Earth while the ordinary populace, for the most part, has been forced to live in space.

The Earth Federation Forces (abbreviated as E.F.F. or EFF) are the military branch of the Earth Federation government. Like the Earth Federation, the origin of the Earth Federation Forces predates the Universal Century. By some accounts, it was formed from the United Nations Forces in A.D. 2009.[1] Compared to the former United Nations Forces, the EFF was given far more power, allowing the Earth Federation government to respond to regional conflicts and natural disasters far more efficiently. The deployment of EFF to regional conflicts continued into the Universal Century. However, after the Earth Federation declared the eradication of conflicts on Earth in U.C. 0022, these conflicts began reducing in scale. In response, the Earth Federation Forces began a gradual reduction of armaments. At this point, the EFF was made up of only three branches: Ground Force, Navy and Air Force. Even as space colonization expanded the Federation's territory into space, the EFF did not create a space force. By the U.C. 0040s, however, Spacenoids - second generation space immigrants - began increasingly demanding autonomy. In response, the Federation government founded the Earth Federation Space Force (EFSF) in the U.C. 0050s. In U.C. 0058, in response to Side 3's declaration of independence as the Republic of Zeon, the EFF initiated the 0060s Military Armament Enhancement Plan, a plan to reorganize the entire EFF with the Space Force at its center.

The Earth Federation Ground Force (E.F.G.F.). Prior to the One Year War, the command of the Earth Federation Ground Force was highly centralized. All important decisions, such as staff management and supplies distribution, were all managed by the general headquarters at Jaburo. With Minovsky Particles restricting combat to within visual range, the EFGF's main battle tank, the Type 61 Tank quickly proved unable to match Zeon's mobile suits, with its advanced data link system and electronics rendered ineffective. As the development of mobile suits was difficult in the short term, the EFGF developed a stop-gap measure: the M-101A3 Regina, an Anti-Mobile Suit Missile (AMSM) designed to be carried and used by specialist squads known as Anti-MS Squads. Though their casualty rates were high, they were able to buy valuable time for friendly units to retreat and regroup. The EFGF began development of the RX-79［G］ Gundam Ground Type, with the EFGF leading the development. The Gundam Ground Type was constructed in very limited numbers and deployed to regions close to Zeon territory in order to check their aggression. Later, the RGM-79［G］ GM Ground Type, a simplified version of the Gundam Ground Type, was also developed. In July, U.C. 0079, the Earth Federation Forces Far Eastern Army created the 1st Mechanized Composite Battalion (commonly known as "Kojima Batallion"), its first mobile suit-equipped battalion.

The Earth Federation Space Force (E.F.S.F.) modelled itself after the Navy and drew members from all three existing branches, with naval officers being the most numerous. Admiral Tianem, notably, was a former naval officer.

Even before the outbreak of the One Year War, the EFF's naval forces were extremely weak and mostly consisted of obsolete ships, most of which were destroyed by Operation British. It received yet another major blow when Zeon forces captured California Base early in the One Year War. A major naval base with submarine production capabilities, California Base housed dozens of submarines in working condition. Due to Zeon's swift attack, Federation forces were not able to destroy them in time, and all of them were captured, allowing Zeon to form its own submarine fleets. Since the EFF prioritized the production of spaceships, the navy was slow to replenish its strength. Due to the persistent threat of Zeon submarine fleets, its main focus was anti-submarine warfare, with Himalaya-class anti-sub light aircraft carriers and Don Escargot anti-sub attack craft continuously in production. However, their numbers were too few, and Zeon retained command of the sea for most of the war. In order to counter Zeon's aquatic mobile suits, the Federation developed the RAG-79 Aqua GM. During the One Year War, its performance proved inferior to its Zeon counterparts.

In the U.C. 0050s, as the Federation began expanding its military might to space, the purview of the air force also expanded to space. As such, the Federation began developing space fighters (such as the FF-S3 Saberfish), high-altitude fighters (such as the FF-6 TIN Cod), and eventually, general-purpose fighters that can function both in space and on Earth (such as the FF-4 Toriares). During Zeon's first landing operation in February, U.C. 0079, the Federation Air Force scrambled to intercept Zeon HLVs. However, since Zeon's space fleet dispersed Minovsky Particles at maximum density in the orbit, guided missiles were rendered unusable, and high-altitude fighters were unable to correctly predict the trajectories of the HLVs and only 32 were shot down. The Federation believed that Zeon's air force would not be a threat to their own. However, due to the use of Minovsky Particles, aerial battles devolved back into WWII-era dog fights, allowing even Zeon's Dopp fighters to fight on equal footing with the Federation's fighters. Meanwhile, many of the Federation Air Force's weapons were rendered useless: the AF-01 Mongoose, a ground attack plane designed for destroying stationary targets and tanks, proved ineffective against the agile mobile suits; the Dish, an AWACS aircraft, was of limited use under Minovsky Particle interference and was relegated to being a VIP transport.

Jaburo is a massive military complex that serves as the headquarters of the Earth Federation Forces during the One Year War. Constructed in an enormous subterranean cavern system in the heart of the South American Amazon River basin, Jaburo was a sprawling complex that included factories, spaceship docks, research facilities, administrative offices, and living quarters for legions of military and civilian personnel, all of which were linked together by an extensive network of roadways, tunnels, and canals. The base spanned an area of 42 square kilometers, and was divided into four quadrants or "blocks" that were designated with the letters A, B, C, and D. It had numerous concealed and fortified entry gates for ground vehicles, boats, aircraft, mobile suits, and spacecraft, and the surface above it was dotted with camouflaged anti-aircraft batteries and monitoring posts. The Federation's early Mobile Suit production began in Jaburo, ultimately producing thousands of units, including many Gundam prototypes and other experimental weapons. Jaburo was again in the spotlight during the early stages of the Gryps War. AEUG forces led by {character} attacked the complex, but the elite Titans had set a trap for them in the form of a nuclear bomb. Jaburo had gradually fallen into disuse after the One Year War, and was only defended by antique units such as the Tin Cod and Saberfish fighters, numerous GM Sniper Customs, GM Cannons, Gouf Flight Types, and Guntank IIs. The AEUG detected the deception and escaped with little to no casualties.

California Base was a massive Earth Federation Forces naval installation composed of 20 large bases on the Californian coast, made up of more than a dozen different naval, aerospace, and weapons development facilities. The California Base was home to the Federation's largest naval yards. During the Principality of Zeon's Earth invasion, it is captured on March 13, U.C. 0079 during Zeon's second Earth drop operation, and became the Principality's major terrestrial base. After Zeon captured it during the One Year War the facility was retooled to produce Zeon submarines. After Operation Odessa, the turning point of the war on Earth, the remaining Zeon forces expended much of the base's fighting strength in a failed assault on Jaburo.

Belfast is a city in Northern Ireland. During the One Year War it became home to a large naval base maintained by the Earth Federation. Although never taken by the Zeon, Belfast was raided numerous times and several buildings throughout the city were visibly damaged.

Torrington Base was an Earth Federation Forces Military Base located in eastern Australia, north of the Sydney Crater (29.3°S, 151.7°E), where the colony drop impacted during Operation British. It was the Earth Federation Forces' main nuclear weapons storage facility. During the One Year War, the base was attacked by Zeon forces which were successfully repelled by the White Dingo Team.

Luna II is an astroid base located at Lagrange point 3. Originally a mining asteroid, Luna II was first known as Juno and used for the construction of the space colonies. Eventually Luna II became the headquarters of the Earth Federal Space Force in UC 0060. In UC 0070, the base was moved to L3 to help in constructing the new Side 7. Located on the opposite side of Earth from the moon and most of the space colonies, Luna II was rather inconveniently situated for a strategic base. However, after the devastating opening month of the One Year War, it becomes the Federation's last remaining foothold in space. Throughout the war Luna II served as a naval base and staging area for the Federation. Although attacked on occasion, Luna II never saw any large scale battles and remained in Federation hands throughout the duration of the war.

Granada is located on the far side of the Moon and is one of the largest lunar cities, second only to Von Braun. Due to Granada's proximity to the Zeon homeland of Side 3, the Earth Federation Space Force establishes a base here prior to the One Year War, but when hostilities commence the base was swiftly overrun by the Principality of Zeon. After the One Year War, Granada once again become a Federation base. However, its citizens remain strongly anti-Federation, and once the Gryps War began, the city openly sided with the AEUG resistance group. Due to the presence of the Flanagan Institute during One Year War, most of the Psycommu and Psycho-Frame related weapons were developed in the city, under the supervision of Anaheim Electronics.

Initially serving along with his comrade Roberto as one of {character}'s wingmen during the One Year War, he escaped to Axis after the end of the war. He left Axis with {character} and joined the AEUG, adopting the pseudonym "Apolly Bay". Apolly later goes on to become the leader of the AEUG flagship Argama's Rick Dias Team. He delivered the newly completed MSZ-006 Zeta Gundam to Kamille Bidan. He was killed by Jerid Messa during Operation Maelstrom.

Ricardo Vega was one of {character}'s subordinates along with Apolly during the One Year War. He escaped to Axis along with Apolly after the end of the war. During his time at Axis Roberto displayed his excellent piloting skills when he overwhelmed Rakan Dahkaran's platoon during live training. He later served as a mobile suit captain during the Axis civil war. He later left Axis with {character} and Apolly to join the AEUG under the pseudonym "Roberto". Roberto is a reliable team player, experienced enough to handle almost any combat situation, and perhaps slightly more serious and diligent than his wisecracking comrade Apolly. After the drop on Jaburo, Roberto accompanies {character} and his allies to the Kennedy Spaceport in order to return to space. Unfortunately, he is shot down and killed by the Titans while attempting to deflect their attack.

Giorgio is an active member of the Zeon Independence League with his sister Nanai Miguel. He was mobilized as a student at the end of the One Year War, and after the war, his skills as a MS pilot were recognized, and he is now ostensibly a member of the Earth Federation Forces. He talked to {character} about the movement within the Federation to gain independence for the Spacenoids. He later lobbied {character} to join the formation of AEUG, and helped him to obtain a federation military registration. He is killed when his cockpit is pierced by a RGM-79Q GM Quel during an engagement with the Titans, who are on their way to attack a conference in Side 1.

He is the leader of a radical faction that seeks to gain independence by continuing the war, and carries out a variety of schemes behind the scenes. Although he lacks individual talent and ability, there are many people who sympathize with him in the Axis, which has a strong desire for independence. He is merciless to his opponents, but has a certain amount of compassion for those close to him, such as when he mourns the death of a subordinate. However, he has a strong tendency to treat others as tools for his own advancement, and he often takes advantage of Admiral Maharaja Karn's moderate nature to behave selfishly. He is also secretly promoting the creation of a clone soldier unit. After being exposed for his alleged involvement in Heinz's death, he launches a coup d'etat on July 31, U.C. 0083, calling himself the "Principality of True Zeon" in order to seize control of the Axis. Although the coup ended in failure, it resulted in encouraging radicalization as expected.

Maharaja Karn was an admiral with the Zeon forces and the father of Neo Zeon leader Haman Karn. He was staying at Granada before the end of the war. He was responsible for the Zeonic army's exodus to Axis base after the One Year War ended. Holding loyal to the Zabi family, Karn declared Mineva Lao Zabi heir to the Principality of Zeon and was named regent of the Axis Zeon faction until she came of age. He died in U.C. 0083. Though attributed to natural causes, Karn's death was partly blamed on the machinations of his military aide Colonel Enzo Bernini, who sought to start another war with the Earth Federation. After his death, his daughter, Haman, inherited his position as Zabi family retainer at age sixteen. Though Karn supported Mineva's claim to Zeon and enjoyed a comfortable position in Degwin's regime, it was implied that he was a supporter of Zeon's founder Zeon Zum Deikun, and was even aware of {character}'s true identity.

{character} met Natalie on Axis in U.C. 0081 on the Axis base. Natalie was a lieutenant and a top computer technician on Axis. At first, {character} did not seem to have much affection nor showed it towards Natalie. Natalie had always liked {character}, but she also reserved most of her feelings for him. But as their relationship progressed, {character} began getting closer to her and developing feelings for her and Natalie also began developing deep feelings for {character} and expressing more outwardly her love for {character}, partly because Enzo Bernini assigned her a mission to seduce {character} to try and persuade him to fight against the Federation. Although {character} later on saw right through the mission Enzo had assigned her, he did not feel any anger and rather felt even more in love with Natalie. {character} really cared for Natalie and said to Natalie, she gave him peace of mind and that he needed her by his side. She became pregnant with {character}'s child. Natalie died before she could give birth, however, allowed to be killed by Haman Karn. Natalie's death was the main reason why {character} left Axis for the AEUG.

The idealistic leader of the AEUG, who travels aboard the Argama during its initial tour of duty. Formerly a high-ranking officer in the Earth Federation Forces, Blex was outraged by the atrocities of the Titans, and used his political and business connections to organize a resistance group. Well-acquainted with his enemies Bask Om and Jamitov Hymen, Blex plots his counter-strategies against them with the calm intelligence of a veteran chess player. He is shot by a Titans operative in the hotel Dakar Prince and later dies in the arms of {character}, telling him to become the new leader of the Anti Earth Union Group.

The AEUG is originally a political movement aiming to reform the corrupt Earth Federation government, but following the "Colony 30 Incident" in Side 1 due to the hands of the Titans, the AEUG takes up arms against them. Composed of dissatisfied colonists, Federation soldiers who disown the Titans and several ex-Zeon officials posing as Federation officers, One Year War veterans Bright Noa, Henken Bekkener and {character} are some of the notable members of the AEUG, alongside AEUG founder Blex Forer and Newtype civilian recruit Kamille Bidan, whose piloting skills and Newtype powers are among the best in Universal Century history. While the AEUG and the Titans are busy fighting amongst one another, the real threat to the peace of the Earth Sphere, Axis Zeon, led by Haman Karn, emerges as the eventual winner. During the First Neo Zeon War, the AEUG's objectives shifted towards fighting the new Neo Zeon movement. However, the bulk of the AEUG was still recuperating from the Gryps Conflict, thus only the Argama and its skeleton crew initially saw action. After the First Neo Zeon War, the AEUG officially disbands, with most of its members going on to form the Federation's Londo Bell task force.

Bright Noa is a loyal and dedicated soldier both in war and peace. He is known for his competence, strong leadership and ability to quickly adjust to complex situations. Thrust into leadership at a young age and by chance, and with a crew comprised largely of civilians and minors, he nevertheless demonstrated an affinity for command, and has been a key member of the Earth Federation Forces ever since. He has regularly proven himself in unfavourable situations, such as his early command of White Base during the One Year War. Eight years after the One Year War ended, Bright, like most of his comrades aboard White Base, was alienated by the High Command of the Earth Federation Space Forces. He was promoted to Commander and assigned to captain the shuttle spacecraft Temptation, whose primary missions were to escort high-ranking Earth Federation officials. Bright defected to the AEUG to aid their struggle against the Titans after being personally assaulted by Titans officers, including Bask Om himself, when he objected to a set of unethical orders. Considering his veteran experience in mobile suit warfare as the captain of White Base during the One Year War, the AEUG commissions Bright with the rank of Captain and gives him command of the assault space carrier Argama, the flagship and crown jewel of the AEUG fleet.[2] Bright Noa worked together with his former adversary, {character}, and together they formed the core leadership of the Argama. With their combined battle experience and expertise of mobile suits, they truly became a force to be reckoned with and not taken lightly. After Commodore Blex's assassination, {character} became the face and idealistic leader of AEUG, but it was Bright who took over command of the military forces. As captain of the AEUG flagship, Bright assumes command of the entire AEUG fleet and effectively leads them in all major battles. As one of the few surviving participants of the Gryps conflict, Bright continued to command the Argama during the First Neo Zeon War.

During the One Year War, Henken was the captain of the modified Salamis-class transport ship Suruga, which belongs to the 7th Fleet and participated in a mission to transport space immigrants from Solomon to Side 6. During the Battle of A Baoa Qu, he left an escape launch with the space immigrants on board to the mobile suit unit "Jack the Halloween" to ensure their safety before entering the battlefield. After this, the Suruga was attacked by the MA-04X Zakrello and sunk, but Henken was rescued safely. Following the One Year War, he joined the AEUG and became the first captain of the Argama in U.C. 0087. Although he was a full-fledged soldier, he was ostensibly the manager of Macdaniel's, a hamburger store in the lunar city of Amman. As the captain of the Argama, Henken commanded the ship during several missions, including the capture of the RX-178 Gundam Mk-II from the Titan headquarters Gryps. He quickly grew attracted to Titans pilot-turned-AEUG pilot Emma Sheen, who refused his advances. Following the rescue of a Temptation-class space shuttle, Henken was replaced as captain of the Argama by the Temptation's captain Bright Noa. Henken went on to captain the Radish, a new battleship in the AEUG fleet. On February 21, 0088, during the final battle for Gryps II, Henken ordered the Radish to support Emma, who was engaged in a battle against Yazan Gable in his RX-139 Hambrabi. Yazan ultimately shot down the ship single-handedly, forcing Emma to watch in horror as Henken died in front of her.

As the chief mechanic aboard the Argama, he and his hard-working crew somehow manage to keep the ship's battered mobile suits in good working order. He also has a keen interest in mobile suit technology and collaborated with Kamille Bidan on designing and upgrading the MSZ-006 Zeta Gundam. He served on the Argama throughout the Gryps War and the First Neo Zeon War, giving advice to both Kamille and Judau Ashta.

The Argama's navigator, Torres was a spacenoid, born and raised in the lunar city of Granada. His closeness in age lead to a kind of sibling rivalry with pilot Kamille Bidan, however, Torres continues to support Kamille throughout the Gryps War. Remaining with the Argama after the Titans' defeat, he joined Bright Noa and Judau Ashta in the fight against Neo Zeon. Later, as the Nahel Argama's navigator, Torres took on something of an advisory role to the novice captain, Beecha Oleg.

Fa was a civilian girl living on the Space colony Green Noa 1 with her parents. The next-door neighbor of Kamille Bidan, she served the role as the replacement caretaker for the emotionally fragile Kamille (who had a very dysfunctional family). She later would also become a surrogate mother to the war orphans Shinta and Qum after joining the AEUG. Fa also had strong romantic feelings for Kamille and her feelings requited by Kamille.

Jamitov Hymen became the leader of the Earth Federation's counter-insurgent organization known as the Titans, which were formed with the stated purpose of eliminating the remnants of Zeon in light of the events that took place during the One Year War and Operation Stardust. However, that was just a smokescreen for their true ambition to dominate the Earth Sphere. After the destruction of the Gate of Zedan, Jamitov attended a conference with Haman and Scirocco. He reprimanded Scirocco for failing to show up at the Gate of Zedan when it was being destroyed, but didn't go any further than that, even though he still didn't trust Scirocco. During the conference, Scirocco said he agreed with Haman about how people "whose souls are weighed down by Earth's gravity" were hardly fit to lead in outer space, irking Jamitov despite his claims of loyalty. Scirocco pulled a gun on Haman, but Char shot him first, grazing his arm. Sensing the danger, Sarah Zabiarov blasted through the conference room with her Bolinoak Sammahn, sending everything into disarray. Jamitov and Scirocco were the only two people left in the remains of the conference room. Scirocco confidently took this opportunity to kill Jamitov and blamed Haman for it.

Zeon Remnants was the term used by the Earth Federation to refer to any member of the Principality of Zeon military who refused to rejoin the Republic of Zeon following the end of the One Year War and continued combat operations against the Earth Federation Forces. After the One Year War, the Principality of Zeon's military units that did not accept the defeat of the Principality of Zeon went into hiding in various regions. Their objectives vary from unit to unit, and there are even battles among these Zeon remnants due to differences in objectives and ideology, but they are generally united in their opposition to the Earth Federation government and the Earth Federation Forces.

Reccoa Londe is a 23 year old intelligence operative for the AEUG who piloted many mobile suits while in service on the Argama. She has short light-brown hair and is 168 cm tall. A warm and generous woman, she is also tough and independent, serving as a mentor to AEUG newcomers. She is a valued adviser to its core leadership. Reccoa does however have a streak of restlessness that causes her to seek out dangerous missions. As the war rages on, Reccoa's female identity begins to clash with her identity as a soldier. She begins to seek comfort from fellow pilot {character}, although he proves unable to provide her with the affection she seeks. The war eventually introduces her to Paptimus Scirocco of the Titans, causing her to be drawn in by his charisma and ideology. Following her defection to the Titans, Reccoa is forced to abandon her morals for the sake of staying close to Scirocco, causing her to lead a mission to gas an entire colony and killing all of its inhabitants. But despite committing such atrocities, she still shows some care about her former comrades, as she was shocked seeing Apolly Bay die in action, and even expressing shock when learning about the deaths of Katz Kobayashi and Henken. Eventually Reccoa comes to believe that all men only use women to fulfill their own ambitions, dying angry and bitter in a battle against Emma Sheen.

Emma was originally a Lieutenant Junior Grade in the Titans, an elite division of the Earth Federation military formed especially to hunt out dissident spacenoids and Zeon remnants. At some point she met Amuro Ray, describing him later as being somewhat distant. She, along with former squadmate Jerid Messa and then shuttle captain Bright Noa witnessed Kamille Bidan's theft of a prototype Gundam Mk-II from a secret facility on Green Noah space colony. This Gundam Mk-II and a second one were appropriated by AEUG. Emma was also there to witness the abusive treatment of Bright Noa by Bask Om and Jamaican Daninghan. Emma was ordered by Bask to fly her Gundam MK-II (the only remaining of the three that hasn't been stolen), to Argama under the intention of a truce. There, she was to deliver a message to AEUG leader Blex Forer. It became evident to Blex that Emma was totally unaware of the nature of the message, hence her seeming lack of concern. The AEUG was to surrender the stolen Gundam prototypes or they would kill a hostage. This hostage turned out to be Kamille Bidan's mother Hilda whom he tried to rescue, only to fail when Jerid Messa, under mission orders, destroyed the space capsule in which she was imprisoned. The Titans subsequently detained Kamille and reunited with his father Franklin Bidan, also being held hostage. Emma chose an opportunity to break Kamille and Franklin out of detainment, disguise them as pilots, and stole the three Gundam Mk-II units. They returned to Argama and Emma announced her wish to defect. Although {character} suspected that she might not be a true Titan, he, along with the rest of the crew, were nevertheless suspicious. Emma was placed on provisional status but it didn't take long for her to prove herself in the eyes of the Argama crew. Emma was later pitted in a duel with former AEUG friend, Reccoa Londe, who defected to join Paptimus Scirocco on the side of the Titans. In the ensuing duel, Emma managed to stab Reccoa's Pallas Athene with Mk-II's beam saber, disabling it. After abandoning her heavily damaged mobile suit to check on Reccoa, Yazan attacked yet again. This time, he fired on the ruined Pallas Athene, destroying it and killing Reccoa, if she wasn't already dead. Emma was caught in the explosion and fatally injured by shrapnel. Emma was soon retrieved by Kamille, but she died in his arms on an abandoned Alexandria-class cruiser. Emma's body would be destroyed when Gryps 2's Colony Laser would fire upon the Titans fleet while her unit was recovered by Fa.

Kamille Bidan is the 18 year old pilot of the Gundam Mk-II. Kamille's appearance was that of a normal teenage male with a well-toned physique. This is offset by his youthful feminine face, which is most frequently shown either stern or scowling, a disposition inherited from his father. He has blue hair inherited from his mother, cut short with curls in back. He is typically seen wearing a light-blue AEUG jumpsuit, and he wore a specialized normal suit when piloting Mobile Suits. He tends to be brash, thoughtless, somewhat self-important, and prone to acting on his own judgment, in addition to being arrogant in his own right. This leads to him getting more than his fair share of abuse, both mental and physical. As the final battle between the AEUG and the Titans approached its fateful conclusion in the Battle of Gryps, Kamille began tapping into the mysterious "Bio-Sensor" in the Zeta Gundam as his Newtype abilities grew, thus unleashing a power never before seen when he destroyed Yazan Gable's Hambrabi. Kamille's anger triggered the Bio-Sensor, which in turn enshrouds the Zeta in a purple glow of power. Kamille used this power to extend the length of the Zeta Gundam's beam saber then sliced Yazan's Hambrabi in two, although Yazan was able to eject in the suit's escape pod. In his final battle with Scirocco, Kamille proved to have the stronger mind (having gained the strength of all the people he loved who had died during the war). Despite impaling the Zeta Gundam into Scirocco's PMX-003 The O, a dying Paptimus Scirocco still managed to unleash a mind-crippling blow to Kamille Bidan, leaving him in a delusional psychotic state.

The Titans were an elite autonomous counter-insurgency group whose purpose was to hunt down the remnant groups of the former Principality of Zeon and any other anti-Earth Federation organization. While technically a part of the Earth Federation Forces, the Titans operated under the sole control of Jamitov Hymen, functioning as his own personal military, and carried out violent actions with impunity, outside the limits of the Federation’s supervision. The Titan ranks were primarily made up of pro-Earthnoid soldiers, most of whom harbored heavy anti-Spacenoid sentiments and were known to use muscle and intimidation tactics to enforce their ranks, even against civilians, fellow Federal soldiers, and lesser Titans officers. The cruelty and oppressive nature of the Titans were eventually exposed when the AEUG captured the Federation capital building in Dakar during a televised assembly of Federation leaders. The Titans attempted to silence {character}, who was making a passionate speech about humanity moving into space before denouncing the Titans, through the use of mobile suits in populated areas of the city with complete disregard for its citizens. Their actions and brutality were caught on camera, which was broadcasted to the entire Earth Sphere, forcing the Earth Federation to publicly acknowledge the monsters they had ultimately created. With both public support and Federation opinion slipping from their hands, the Titans were effectively forced onto the offensive, which resulted in them ironically allying themselves with the recently returned Axis Zeon forces, the very thing they were formed to oppose. Towards the end of the Gryps Conflict, the AEUG successfully captured the Titans' Gryps II colony laser, which they used to wipe out the majority of the Titan fleet, with their leadership eventually lost in the ensuing three-way conflict between the AEUG, the Titans and Axis forces. Although the vast majority of Titans personnel died in the conflict, those who survived the war broke away in several directions. Many returned to the Earth Federation and either resumed military service or were subjected to trials for their war crimes. Other members unwilling to surrender formed rebel groups such as New Desides, but were eventually annihilated by the Earth Federation’s Task Force Alpha in early U.C. 0088. The remaining Titans remnants either joined Axis Zeon in their preparation to invade Earth or fled to Mars seeking sanctuary under the protection of ReZeon, who accepted them under the pretense of bolstering their own ranks despite the Titans’ begrudging attitude.

Jamaican is the quintessential Titans officer, arrogant and heavily abusive towards his own men, and openly looked down upon every last one of them. As a Titans staff officer, Jamaican was one of Bask Om's top henchmen, and often took point as the Titans primary field commander, allowing Bask to administrate more from behind the scenes. Unlike his superior however, Jamaican was not opposed to having spacenoids included in the Titans, believing that such an action may lessen the AEUG's influence in space. Jamaican's smug attitude often causes him to come into conflict with certain other Titans; specifically Paptimus Scirocco and Yazan Gable. Assigned to pursue the AEUG flagship Argama after the rebels stage their daring raid on the Titans headquarters, Jamaican took command of the cruiser Alexandria and chased the Argama back and forth across the Earth Sphere. When the AEUG's forces head to Earth to attack Jaburo, he returned to Gryps. Months later, he continued to command the Alexandria during Operation Apollo. After the operation, Jamaican took command of the Titans garrison from Scirocco, and ultimately lost the city during the AEUG's recapture of Von Braun. To rectify his humiliation, Jamaican attempted to drop a colony on Granada, but through the actions of the AEUG, the colony misses its target. After the failed colony drop, he decided to return to Gryps to resupply, but Yazan has other ideas. During the Skirmish at the Gwazine Wreckage, Yazan manipulated AEUG pilot Emma Sheen to fire her Super Gundam's long beam rifle at the Alexandria's bride, killing Jamaican for him.

When Haman was young, and first discovering her new type powers in the midst of war, she latched on to {character} for support and comfort. She looked up to him, and admired him, which is why she may have fallen in love with him so easily. {character} did not make any attempt to push her away. However, it should be made clear that he never developed the same level of feelings for her. The relationship was always a one-sided one, nor did they ever actually date. {character} respected Haman and felt her future was important for the remnants of Zeon and Axis, and that he should be her guardian, even risking his life for her, but he felt little more than that. Eventually {character} grew to distrust Haman, after seeing how her growing power began to change her, and after experiencing a personal tragedy on Axis, but Haman never forgot the feelings for him buried deep in her heart. She tried repeatedly to bring him back to Zeon, and to her. But by this time, her feeling for him have been twisted by rage, and he continued to harbor little more than distrust for her. Haman died during the events of the First Neo Zeon War.

The massive asteroid is probably best described as being vaguely star-shaped. The majority of its body is a wide flat plane that is somewhat circular when viewed from above. From this plane sprouts three triangular "mountains" or "spires"; two jutting from the bottom and one arising from the top. It is not clarified if these formations were always part of the asteroid's natural appearance or if mining operations carved them into those shapes, though one can presume so, as there are specific sections around the bottom "mountains" where artificial cutouts are clearly made. The Axis base was built by the Principality of Zeon in UC 0072. It was used, like many other asteroids, as a resource mining base. Given its position in the asteroid belt between Mars and Jupiter, it was also used as a stopping point for the Jupiter Energy Fleet during its trips between Earth and Jupiter. Due to its remote location, Axis did not play a large role in the fighting of the One Year War. However, it remains important to the conflict as a refuge for renegade Zeon soldiers. After the Battle of A Baoa Qu, the Principality of Zeon officially surrendered to the Earth Federation; however, many soldiers in the Zeon military refused to accept this outcome. Some, such as the Delaz Fleet, chose to remain hidden in the Earth Sphere. Most, however, fled the Earth Sphere and traveled to Axis, often with their families and dependents in tow and the influx population grew to 30,000. Many of the people who escaped to Axis were also Zeon engineers, and the development of new mobile weapons and space vessels continued there. At some point, Axis was fitted with large thermonuclear pulse thrusters for propulsion. On February 6, UC 0086, these thrusters were activated, and Axis began to travel toward the Earth Sphere. The trip took nearly two years; twenty months after it began to move, Axis arrived in the Earth Sphere, finding itself in the middle of the Gryps Conflict. Haman Karn used Axis as a mobile base and headquarters for her forces in the battle against both the AEUG and the Titans. At one point in the conflict, Axis itself was used as a weapon, ramming the Titans' base the Gate of Zedan and destroying it, though Axis suffered only minor damage. When Haman Karn declared herself the leader of the First Neo Zeon on UC 0088, she continued to use Axis as a mobile headquarters and base. It was infiltrated several times by the AEUG, specifically Judau Ashta, but continued to be used throughout the conflict. Towards the end of the civil war between Haman and Glemy Toto's forces, Glemy takes control of Axis and uses the asteroid and its satellite, Moussa, to crash into and destroy Haman's colony, Core 3. After Neo Zeon was defeated, the base was abandoned for some time.

Bask is a brutal and despicable man who despises the Spacenoids, massacres civilians and attacks the enemy without regard for friendly forces in the line of fire. He is extremely arrogant, and will physically abuse anybody who questions his orders without shame. He also has the habit of beating anyone under his command who questioned his orders, including those of the non-Titan Federation army, bolstering his command through intimidation and fear. In December of U.C. 0087, Bask took command of the Titan flagship, the Dogosse Giar, and began using the deadly super-weapon, the Gryps 2 colony laser, to attack the space colonies. After the death of Jamitov Hymen at the hands of Paptimus Scirocco, Bask stood as the only obstacle preventing the latter from acquiring complete control over the Titans. He ultimately met his end when Reccoa and several other minions of Scirocco attacked his ship, the Dogosse Giar, while they were executing a mission with Rosamia Badam piloting the MRX-010 Psycho Gundam Mk-II. Due to all the confusion, Bask and his men were easily overwhelmed and defeated when Reccoa destroyed the Dogosse Giar with a direct shot at the bridge, killing Bask.

Operation Stardust was a large-scale military conflict between the Earth Federation Forces and the Zeon Remnants group "Delaz Fleet" that took place in late U.C. 0083. Though brief, this conflict had lasting impact, leading to a second colony drop on Earth, the rise of the Titans, and eventually, the Gryps Conflict.

A direct descendant of the RX-78-2 Gundam developed by the Titans, the Gundam Mk-II is the first mobile suit to utilize the new movable frame concept. In this new concept, rather than merely serving as a structural framework, the movable frame incorporates all the mobile suit's vital mechanisms, including the actuators and control systems required for movement, and excludes the mobile suit's weapons, armor, and propellant tanks. This approach dramatically improves the mobile suit's responsiveness, reliability, and energy efficiency, as well as making it far more agile than traditional designs. Another characteristic of the Gundam Mk-II is that some of its legs' movable parts are exposed and this design feature is based on the prevailing idea at that time that avoiding being hit by the enemy is the preferable choice. The origin for this idea is because no existing armor can fully protect against beam weaponry, thus it is better to increase the mobile suit's mobility by weight reduction rather than equip more armor which would lead to a higher weight and lower mobility. The mobile suit also has what had become the standard 360-degree panoramic screen and linear seat fitted in a circular cockpit that also functions as an escape pod. The multiple panels of the panoramic screen make up a single 360-degree display, covering the entire inner surface of the cockpit. The image displayed on this screen is a computer simulation constructed from the cameras distributed around the mobile suit's exterior. The viewpoint is that of the mobile suit's head, and the image is carefully edited to remove the mobile suit itself. The linear seat is suspended in the center of the cockpit, supported by a linear arm which electromagnetically counters G-forces and impact shocks in order to protect the pilot. Together, the panoramic screen and the linear seat gives the pilot a larger field of view and eliminates blind spots.

On 31 July U.C. 0085, a massive yet peaceful protest was held in Side 1's 30 Bunch (the 30th Colony in Side 1's territory) against the actions of Titans, but soon turned into chaos, with riots breaking out throughout the colony. After repeated attempts by the Federation Forces to calm the riots failed, the Titans were dispatched to put it to an end. The Titans responded by shutting down the colony's air supply and using G3 Gas to kill its entire population.

In March, U.C. 0087, {character} lead Apolly Bay and Roberto to infiltrate Side 7 Green Noa 1 and attempted to seize the Titans' new mobile suit RX-178 Gundam Mk-II. With the cooperation of Kamille Bidan, a civilian from Green Noa 1, he succeeds in capturing it. This incident triggers a full-scale armed conflict between the AEUG and the Titans.

The conflict ended in early U.C. 0088 with the pyrrhic victory of the AEUG over the Titans during Operation Maelstrom and the Battle of Gryps, but left the AEUG severely weakened and allowed Axis Zeon (which was later renamed Neo Zeon) to return to the Earth Sphere, leading to the outbreak of the First Neo Zeon War.

The war started on March 3, UC 0088, 11 days after the Battle of Gryps, the final pitched battle of the Gryps Conflict that resulted in the annihilation of the Titans and the loss of most of the AEUG combat forces. With both the Earth Federation and AEUG weakened by that civil war, and Axis Zeon suffering minimum loses, Haman renamed her forces "Neo Zeon" and took the chance to revive the glory of the Principality of Zeon, with Mineva Lao Zabi, the last surviving member of the Zabi family, as the figurehead ruler, although Haman was the de facto leader. However, a rebel faction under the ambitious Glemy Toto turned against Haman, and the war again became a three-way struggle. The conflict ended during the Battle of Axis, after both the loyalist and rebel Neo Zeon factions virtually wiped each other out, with both leaders dying in battle. With its leadership gone, and Mineva revealed to have disappeared after being replaced by a stand-in since the end of the Gryps Conflict, Neo Zeon surrendered to the Earth Federation on January 17, UC 0089.

{character} originally met Nanai on an expedition to the Republic of Zeon for Axis in U.C. 0083. She was an assistant at the Newtype labs where Lalah Sune had undergone many tests and performed some of those same tests on a young Haman Karn to test her potential. Nanai was only 16 at the time and clearly showed a great respect for {character} and his veteran status. Eventually, a decade later, {character} and Nanai again met sometime during or after the first Neo Zeon conflict. The exact details of how and why they came to date is not known, but {character} accepted Nanai as his formal love interest, despite still being unable to move on from his former love of Lalah Sune. Nanai passionately loved and admired {character} with all her heart, while {character} would only partially return this affection. He cared for her on at least some level, but he was more focused on his objective of avenging Lalah and hurting Amuro than anything else at this time in his life.

In the aftermath of the First Neo Zeon War, the Earth Federation formed the peace-keeping organization known as Londo Bell in an attempt to make sure any sort of uprisings like Haman's were quelled. Though Londo Bell was instructed to use more passive methods, this led to angry sentiments from the spacenoids, remembering the atrocities made by the Titans. On December 22, UC 0092, {character} returned from hiding after his disappearance during the Gryps War and declared the creation of the second Neo Zeon. He occupies Sweetwater, a colony filled with refugees from other ravaged colonies, in a bloodless occupation. This is especially true when the citizens there welcome him with open arms. On February 27, UC 0093, {character} openly declares war on the Earth Federation with the intent on bringing every last human into space to begin their ascension. The Earth Federation responds by building up Londo Bell's forces. However, it isn't enough.

Londo Bell was established on March 21, U.C.0090, after the First Neo Zeon War, and was tasked with investigating and fighting anti-Earth Federation activities. The name "Londo Bell" comes from "the bell of Londenion (the old name of London meaning 'wasteland')", and also means "one who rings the alarm bell in times of emergency".[1] Its headquarters were located in Londenion in Side 1, and among the organization's ranks were former AEUG and Karaba members. Londo Bell was first commanded by Bright Noa, with its mobile suit combat squads led by ace pilot Amuro Ray. In the event of a major insurgency such as a Zeon uprising, Londo Bell would respond as the tip of the Federation's spear. However, due to the actions of the late Jamitov Hymen and the Titans during the Gryps war, Londo Bell was given a much lesser degree of autonomy from the main Federation Forces, and as a precaution was barely built to even a tenth of the size of the Titan's numbers during their heyday. Despite these precautions, there were those who would constantly hold Londo Bell in suspicion of trying to follow in the Titans' footsteps. In U.C. 0091, the group fought Titans remnants at Side 1. The Titans remnants deployed the new MRX-013-3 Psycho Gundam Mk-IV G-Doors, but it was swiftly destroyed by veteran ace pilot, Amuro Ray. In U.C. 0093, former Zeon officer/AEUG leader {character} returned, after being missing-in-action following the Gryps War. After occupying the refugee colony Sweetwater without firing a single shot, he publicly declared himself the new leader of Neo Zeon, and shortly thereafter started a new war against the Federation. As a countermeasure, the military rapidly increased the size of Londo Bell in anticipation of the Second Neo Zeon War.

The Re-GZ was developed by Anaheim Electronics as a simplified variant of the company's masterpiece, the MSZ-006 Zeta Gundam. Consideration for mass-production was taken into account, and it aimed for a lower cost than the limited-production Zeta Plus series. The basic design of Re-GZ's body follows that of the Zeta Gundam's MS form while parts such as the arms are shared with the RGM-89 Jegan. The transformation mechanism was considered too costly to mass-produce, and was removed in favor of a special Back Weapon System (BWS), which the Re-GZ can dock with to change to a Waverider-like form. The BWS was developed with reference to subflight systems such as the Base Jabber and FXA-05D G-Defenser, and in particular, the MSZ-006R Zeta Plus R (a machine with a large detacheable backpack) from the Zeta Plus series. The BWS is armed with additional beam weapons and propellant tanks. As the Re-GZ was developed during a time where large-scale battles did not occur and it was more expensive than other MS, so only one prototype was built.

A state-of-the-art machine adopted by the Earth Federation Forces in U.C. 0089 as its main force mobile suit, the RGM-89 Jegan comes from the lineage of the RGM-79 GM as inferred by its "RGM" model number. However, it was not developed by the Earth Federation Forces' own engineers like most previous RGM series mobile suit. Instead, it was produced and supplied by Anaheim Electronics (AE). Created through combining the Earth Federation Forces' expertise of the GM series with AE's MS development technologies, the Jegan's performance is significantly higher than the RGM-86R GM III. It also has improved productivity due to the use of Titanium Alloy Ceramic Composite armor, as well as high operability, and excellent versatility. All these allows it to become the "next-generation standard MS". The Jegan highly exemplified the original concept of MS being "mobile infantry for melee combat", and is designed for close combat in and around space colonies. It can also operate under gravity without any modifications. With a backpack containing a single main thruster, two small thrusters at the bottom, and two articulated vernier arms at the top, the Jegan's thrust and acceleration performance could match-high mobility-type machines from the Gryps War-era. Its backpack also featured exchangeable propellant tanks. Also notable are the Vernier's for attitude controls on the front shoulder armor, enlarged centre shoulder armor sections to fit the side thrusters, and a calf-mounted thruster on each leg. The use of lightened armor grants the machine high maneuverability, its front skirt armor is removed to maintain the legs' range of articulation, while its head has a long-range sensor installed in the forehead in addition to the fixed main sensors. The Jegan is armed with mainly short-range weaponry, including a beam saber, a short-range type beam rifle, three hand grenades, a vulcan pod system, and a shield with twin missile launchers.

A high-performance ship that has both sufficient mobile suit operation capability and high bombardment capability. The ship is armed with five two-barrel main beam cannons, twenty-two secondary anti-aircraft guns, and six missile launchers. It also has eight engines and a pair of cooling fins to help improve fuel consumption and increase speed. It has two bridges, a regular bridge and a battle bridge that also serves as an escape pod. There is a catapult for launching mobile suits on each side of the ship, and a landing deck at the rear. The Ra Cailum also possesses the ability to deploy multiple decoy balloons that expand to the same size and shape as the ship itself. Although a close visual inspection would reveal which "ship" is real or fake, they were useful for fooling long-range inspection and sensors thanks to Minovsky particle interference.

In U.C. 0093, Zeon Zum Deikun's son, {character}, created a second Neo Zeon known as the "Newborn Neo Zeon". This movement was founded under the ceremonial goal of "speeding up" the space migration of all of humanity, so the theoretical evolution of humanity into Newtypes could be realized. Char's plan involved a series of massive asteroid drops against the Earth, ultimately leading to an eternal nuclear winter, rendering the planet uninhabitable. The final collision attempt was to involve the Axis asteroid, headquarters of the previous Neo Zeon movement.

Rezin Schnyder is an extremely skilled and hot-headed pilot; so confident is she in her own ability that she regularly disobeys orders and simply does what she wants on the battlefield. Arrogant, sarcastic, and rude in general, she has little respect for her colleagues and makes it known: rebuking well-wishes from Nanai Miguel with a sarcastic "Oh gee, thanks a lot!", calling Gyunei Guss as a "fake Newtype".

Gyunei is a Cyber Newtype serving under {character}'s second Neo Zeon movement. Unlike past Cyber Newtypes, Gyunei is in full control of himself physically and mentally, and uses his modifications to full effect on the battlefield. Despite his proficiency, Gyunei feels frequently ostracized, feeling that people only recognize his accomplishments due to his enhancements as opposed to skill, causing him to perceive most people as belittling him. Gyunei served as a bodyguard and wingman for {character}, who by this time had become the leader of the Neo Zeon movement.

A pilot belonging to the Principality of Zeon's Assault Mobile Force's special contingent, the Marchosias Corps. He was a member of the G Platoon led by Doug Schneid. He was living with his mother in Side 3, but was removed from the elite course when his mother was suspected of being in league with the Federation. However, because of his excellent performance in training, he was transferred to the Marchosias Corps. During the Battle of A Baoa Qu, he encounters the RX-80PR Pale Rider, which has been giving him a hard time so far, and with the help of Guy Helmuth and Liberio Lincke, he is able to disable it, but both of them are killed in battle. He learns that Chloe Croce, the pilot of the Pale Rider, was a young girl, and that she was only one of the victims of the war, and protects her. After that, he continues to fight with her in the AEUG and Neo Zeon Army, but sometimes he remembers the resentment he felt when his comrades were killed, and thinks about shooting Chloe's machine from behind on the battlefield. However, he never does so, and treats her kindly out of compassion for her. After joining up with the Newborn Neo Zeon in 0090, he received the new AMS-119 Geara Doga for practical testing.

Originally a gentle and innocent girl, Chloe was turned into a merciless killing machine by the enhancement procedures she underwent, which dulled her mind and slowly made her lose her memories. Though she feared that she would eventually lose herself, she felt a sense of freedom like nothing else when piloting mobile suits. Unfortunately for her, as she participated in battles, she was given more drugs, causing her to lose even more of her memories. After she was defeated during the Battle of A Baoa Qu, she had lost almost all of her memories. She fell in love with Vincent Gleissner and decided to start her life anew. Though she was aware that Vincent was under orders to keep an eye on her, and has his gun pointed at her back during battles, she was still willing to sacrifice her life in order to protect him, her only wish being that Vincent would be the one to pull the trigger on her at the end, and that he would cry for her after her death. Due to the effects of her memory impairment, she became attached to Vincent, and they continued to fight together in various camps, and in the year 0090, she joined the Newborn Neo Zeon, but her body was nearing its limits due to the effects of experiments and HADES.

The AMS-119 Geara Doga is a general purpose mobile suit with technology and design features descended from the old MS-06F Zaku II. It is developed based upon the design of an Axis machine taken out by members of Neo Zeon following the group's defeat at the end of the First Neo Zeon War. Since the resources of Char's Neo Zeon are limited, the Geara Doga was not a particularly high-performing unit when compared to the machines used by Haman Karn's Neo Zeon four years earlier; however, it was well in line with the style of mobile suit design of the day. Its performance was also sufficient for most soldiers, easy to mass-produce and remains a threat for the Earth Federation's own mass-produced suit, the RGM-89 Jegan. The Geara Doga has a wide variety of weapons to cope with different combat situations. Its only fixed armaments are a beam sword-axe for close combat and an shock anchor. It can be equipped with a shield with four grenade launchers and two different types of beam machine guns, with one capable of mounting additional weaponry. The Geara Doga is fitted with old Zeonic-style mono-eye head sensors able to detect targets at a longer range and thus make a faster offensive; however, when within combat range, the sensor's performance becomes limited in terms of target-tracking. The basic specifications of this machine is for space combat, and a backpack for long-distance cruising is standard equipment. With its versatility, maneuverability, and maintainability, the Geara Doga combines all the necessary factors as a practical weapon while earning the trust of mechanics and pilots in the field.

After {character} returned as the leader of his own Neo Zeon faction in U.C. 0093, he ordered his engineers to create a new mobile suit which would fit his piloting skills and Newtype powers. The result was the MSN-04 Sazabi, which was later built by the Luna-based contractor Anaheim Electronics. With an overall height of 25.6 meters, the Sazabi is much bigger than most standard mobile suits, but thanks to the use of lightweight armor materials and a great number of thrusters it is much faster and maneuverable than other suits. The suit is armed with an abdomen-mounted scattering mega particle cannon, a beam shot rifle, a pair of beam sabers stored in the arms and a shield with three missiles as well as a beam tomahawk. Because Char is a Newtype, the Sazabi was also equipped with six funnels which the pilot could control through his psycowaves via a Psycommu system. The Sazabi was also the first MS to be equipped with the revolutionary new Psycho-Frame cockpit. This system featured microscopic psycommu receiver circuits installed throughout a mobile suit's internal frame and cockpit walls. These tiny circuits amplify and transmit a Newtype pilot's psycowaves, enabling the mobile suit to respond instantaneously to mental commands.

Based on the frame of the mass-produced AMS-119 Geara Doga, the MSN-03 Jagd Doga was a special mobile suit designed to be used by Neo Zeon's Newtype pilots. Developed using data from the evaluation tests of the AMS-120X Geara Doga Psycommu System Test Type and the AMS-119N Röte Doga, it has a Psycho-Frame cockpit for controlling the six funnels stored on its shoulder-mounted funnel pod shields. Unlike previous mobile suits that utilize funnel weapons, the Jagd Doga cannot recharge its funnels. Other weapons of the suit include a beam saber with attached heat knife for close combat, two triple missile launchers behind the funnel pod shields, and a beam assault rifle for Gyunei's unit, while Quess' unit carried a mega Gatling beam gun. The Jagd Doga's sensors, thrusters, and nuclear reactor have also been significantly improved compared to those on Geara Doga. As a result, it has greater speed and mobility, and more power for its weapons and other systems. In terms of performance, the Jagd Doga was the second most powerful mobile suit in the Newborn Neo Zeon's arsenal, second only to the MSN-04 Sazabi.

The Geara Doga Psycommu System Test Type was the earliest mobile suit developed by {character}'s Neo Zeon for Newtype-use. It used the movable frame of the AMS-119 Geara Doga, and was equipped with the Psycommu System as well as remote weaponry known as 'Funnels'. Due to the failure to miniaturize the Psycommu System, the task of developing Newtype-use MS was later passed over to Anaheim Electronics, who used the Geara Doga Psycommu System Test Type to develop the MSN-03 Jagd Doga. Compared to the Jagd Doga, the Geara Doga Psycommu System Test Type had higher firepower but inferior mobility.
