Kimberly Ann Possible

Dr. Ann Possibl​e is a neurosurgeon, who lives and works in Middleton. She is a devoted wife, mother, and doctor, with a cheerful demeanor and an understanding attitude. Ann looks similar to her daughter, Kim, while being taller in height with a lighter shade of hair, blue eyes, and a more ruddy color to her skin. Her casual attire usually consists of a magenta sweater and a purple skirt with a matching skirt and high-heels. Her business attire is much the same, only with a dark purple suit jacket or a white lab coat. When performing surgery, she wears green surgical scrubs.

Dr. James Timothy Possible is a brilliant rocket scientist. He is devoted to his work at the Middleton Space Center and to his family. He has a very fatherly personality, hearkening back to the father and scientist stereotypes of the 1950s. He is the father of Kim and is in his mid to late 40s.

Jim and Tim Possible are identical twin geniuses brothers, and younger siblings of Kim, whom she calls "Tweebs"–a portmanteau of "twin" and "dweebs". They are distinguished by the major coloring of their clothing; Tim habitually wears red, while Jim wears green. When they are not harassing Kim, they are making trouble with their scientific experiments and inventions such as launching rockets or sending out screen savers of an unsuspecting Kim to all of Middleton.

It is referred to as one of three cities in the Tri-City area. The other two being Upperton and Lowerton. Most scenes of Middleton are those of a quiet, suburban town, although other scenes show it to also have an active urban area with a large population base, an extensive infrastructure, and considerable cultural amenities. Middleton is described as being a modern, planned community in the new urban utopian mold. Parkways, porches and picket-fences define the landscape located somewhere in the state of Colorado.

Middleton High School is the only known high school in Middleton and is the high school that Kim and Ron attend. It's also part of the Middleton Unified School District. The school mascot is the Mad Dog, brought to life by Ron. Middleton High School has stairs as well as ramps and elevators for the handicapped. The Middleton High School competitive teams have a rivalry with the Lowerton Lemurs. Competitions between these two schools are always heated.

Middleton Mall is at least a two-level shopping mall located in Middleton. One of the many stores inside this mall is Club Banana, which is frequented by Kim and Monique where they both work part-time. There is also a food court which has some fast food restaurants, such as Pickle on a Pike, which is one place that very briefly hired Ron before they fired him because of an accident he had while working there.

Ronald "Ron" Stoppable is Kim's lifelong best friend, mainly serving as her faithful sidekick during missions. He is portrayed almost oppositely to Kim, typically getting low grades and tending to slacking off, and overall being shown to be less capable than her. He is also shown to be an eccentric student with an erratic and contradictory personality. Some of his schoolmates view him as weird and odd and often refer to him as a "loser".

Monique is Kim's closest female friend and confidante. She serves as a conversation friend for subjects that Ron has no interest in or knowledge of. Monique has a no-nonsense attitude, a good eye for fashion, and a good heart. Monique is responsible, down-to-earth, and very fashion conscious. She is a highly loyal friend to Kim and Ron, to the point where she will occasionally force them to address their own personality flaws, especially if she considers such traits to be self-damaging or unattractive. She has lost her patience with Ron several times, as his habitual laziness or deviation from the norm sometimes puts Kim or Monique herself in less than desirable situations.

Club Banana is considered the trendiest place to shop for clothes. However, it is a seldom mentioned fact that both Club Banana and the popular bargain store, Smarty Mart, were owned by the same company. Most of the clothes that are sold in both stores are pretty similar to each other—in fact there were only a few key differences between the two stores such as Club Banana's much more expensive compared to Smarty Mart. Also, since Club Banana is still a fairly high-end store, they (unlike Smarty Mart) carry actual designer labels. Kim and her best girlfriend, Monique, meet at Club Banana and are frequent shoppers there, which entitled them to exclusive benefits, such as attending a preview of the Cleopatra's Closet exhibit at the Middleton Art Museum. Kim is also a charter member of the Club Banana Club. Monique works part-time at Club Banana, eventually being promoted to assistant manager, and is the one who helps Kim get her job at Club Banana.

Steven "Steve" Barkin is a substitute teacher at Middleton High School, which is attended by Kim and Ron Stoppable. For reasons of frequent injuries, sickness, or vacation among other staff members, Barkin teaches a variety of classes, ranging from gym to home economics. Barkin is tall with a large muscular build. He has dark eyes and dark hair cut into a neat flattop. Barkin's manner is a gruff, no-nonsense, quick to anger, and contains little to no sense of humor. He is typically abrupt and abrasive with students, and is a stickler for punctuality and proper decorum. Despite this, Barkin tries to take a "tough, but fair" approach. He refuses to play favorites in his classes, and will give "credit where credit is due" regardless of what he thinks of the student at other times. Additionally, while Barkin typically likes to be in charge, he has also been known to defer to others quickly, and without argument, when he recognizes that their experience outstrips his own. He is revealed to have served in an unspecified war, where he achieved the rank of Lieutenant. Which explains his conducting himself more like a drill sergeant than a teacher. His military service would also explain his strict no-nonsense attitude. He tends to panic in a major crisis, which indicates that he may suffer from Post Traumatic Stress Disorder, aka shell shock, presumably as a result of some bad wartime experiences.

Bueno Nacho is a Tex-Mex fast-food restaurant chain. Store #582 serves as a popular hangout spot for Middleton High School students, especially Kim and Ron Stoppable. It features a standard store design, including the signature Sombrero-shaped roof. It is located in what appears to be a light commercial area. It is within walking distance of Middleton High School. Bueno Nacho's menu includes traditional tortilla-based dishes, and commonly seen items are Mexi-Mushroom Wrap[4], nachos, tacos, and burritos. Several menu items were named by combining such dishes: the "chimirito" (chimichanga and burrito), the "quesachanga" (quesadilla and chimichanga), and Ron's personal invention of the "naco" (nachos and taco). There are also breakfast dishes, such as an egg quesadilla called a "huevadilla" ("Huevo" is the Spanish word for "egg"). The menu also had at least eight combo meals, and the option of "Grande Sizing" meals if larger portions were desired. Bueno Nacho hosted various promotions, including Naco Night, Hablamos Salad, and packaged toys such as the "Lil' Diablos".

Cow and Chow is a fast food place in Middleton. This place is apparently not one of Ron's favorite fast food places.

JP Bearymore's Pizza Party-Torium is a Chuck-E-Cheeze inspired resturaunt and one of Ron's favorite places to eat, and he has been a preferred customer there for fifteen years. The Pizza Party-Torium is located somewhere in Middleton and Kim does not like this place, only coming to it out of begrudging necessity.

Middleton Medical Center is Middleton's local hospital. Dr. Ann Possible works there as a neurosurgeon. It is mentioned that the hospital contains at least an emergency room, nursery, pediatric ward, and several surgical theaters. There are at least a few volunteer programs associated with the medical center, such as the Sunshine Spreaders, and the annual haunted house on Halloween.

Middleton Park is a local park in Middleton. The park has a playground area for children, but mostly seems to contain large, grassy areas, sidewalks, trees, and benches. There is also a pond and a greyish building of some form is located behind the park.

The medium-sized split-level, located somewhere in Middleton, that is home to Kim, her father, mother, and brothers. It is next door to the Stoppable's house. A steep curvature, surrounded by rolling hills covered in lemon trees. The kitchen, family room, master bedroom, and the boys' bedroom are apparently on the main level. Kim's bedroom is a loft with large windows, presumably the space visible over the garage. The garage itself appears to be a 3.5 car, with two narrow garage doors.

Smarty Mart is a Wal-Mart-type Super-super convenience store. Smarty Mart and Club Banana are owned by the same parent corporation. Smarty Mart is reviled by Kim for its low prices, "discounty" atmosphere and general unpopularity with fellow trend-keepers. Ron Stoppable was a Smarty Mart enthusiast, and shopped there so frequently he knew the Middleton store's greeter Oscar personally.

The Middleton Motor Lodge is a hotel and lodge located somewhere in Middleton. It does not contain a dojo, but it does contain a gym and spa. The rooms are either single or double. The hotel uses electronic key cards. There is large room for meetings with a stage. They have valet parking. Pets are not allowed.

The Middleton Space Center was, not surprisingly, typically the site of rocket launches, as well as the target of hi-tech thefts. It is the workplace of rocket scientist Dr. James Possible.

The Middleton Institute of Science and Technologies, commonly shortened to M.I.S.T. by its students, is an extensive and science-oriented school of higher education. Dr. James Possible attended this school. The Middleton Institute of Science and Technologies consists of several different buildings for its various areas of study. Earth Sciences alone had at least nine buildings devoted to them. It also boasts a prominent Space Age Populuxe-themed structure similar to Los Angeles International's Theme Building. Some classes offered included Principles of Microdynamic Energies, and Introduction to Computational Methods of Nano Bio-Technologies.

Middleton Landfill is where much of Middleton's trash ends up. The landfill is located somewhere in Middleton, though more than likely in a less populated area or the outskirts, due to the smell and the absence of nearby buildings. The landfill has a wooden walkway that offers a fairly wide view of the area.

Middleton Zoo is a zoo located in Middleton. While Ron was seeking part-time jobes, this was one of his short term employers. They hired him to feed the lions, but he lost the job due to Bringing his own raw meat from home and Poking the lions with a stick.

The Stoppable's house is located in Middleton right next door to the Possible's house.

Bonnie Rockwaller is Kim's Middleton High School classmate, fellow cheerleader, and her archrival since at least middle school. Bonnie is a brunette of average height with shoulder-length hair in a shag cut, teal eyes, a slender but curvaceous figure, and may be around 105-lbs. Bonnie was generally considered to be a very rude, snobby, self-absorbed girl with a dismissive, cold attitude, and a superiority complex, especially toward Kim, Ron Stoppable, and their friends, whom she largely considered to be beneath her. She was driven by a near-constant need for recognition, and almost always demanded to be the center of attention, no matter what the situation was. Bonnie's self-obsession was such that she could not be bothered to care about the problems of others, even if they were far more important than her own desires.

Drew Theodore P. Lipsky, alias Dr. Drakken, is a genius robotics inventor and engineer, considered by Kim as her arch-nemesis. A self-proclaimed mad scientist, Drakken dreamed of world domination, but was constantly thwarted by the efforts of Kim. Drakken is of average height and build with light-blue skin, long black hair tied in a ponytail, a scar under his left eye, and a thick unibrow. Drakken's primary outfit is a blue double-breasted coat and trousers, with black gloves and boots. He also wears a wide belt and a black collar, both of which are embossed with pale green circles. Drakken was a self-categorized "evil megalomaniac," and fueled by pettiness and jealousy. He was constantly boastful about his plans, frequently ranted about his successes while they lasted to whatever audience was available, which was usually Shego. He became irritated whenever someone reminded him how Professor Dementor enjoyed a more impressive reputation as a villainous mad scientist.

Shego is a villainess who operates as a criminal mercenary, working for Dr. Drakken as his chief enforcer and henchman. Since her main duty to Drakken entails stealing things on his request and protecting him from harm, she frequently engages Kim in battle, and although she is under contract with the scientist, Shego has occasionally worked with other villains. Shego is a tall, beautiful, hourglass-figured and faded light green-skinned woman. She sports long, black hip-length hair with noticeable light green accents, forest-green eyes and arched-styled brows, and her lips are naturally a black in color. In terms of attire, Shego is always seen with a green-black color scheme; her signature attire consists of a full-length, tight-fitting high-collared catsuit that sported an asymmetrical harlequin-pattern that is colored in black and bright light green. She also wore one glove and one boot of each color, and an accessorized utility pouch which is strapped around her lower left leg. Shego has an explosive temper, and is known to react with violence, or at least the threat of it, over even slight offenses, depending on the person responsible.
