Kim Possible is an 18-year-old university freshman who has long straight red hair, a fit athletic curvy body who spent most of her adolescence balancing teenage life with saving the world. Confident, driven, athletic, and compassionate, Kim began taking odd jobs as a young teen under the motto that she could “do anything.” Before long, those jobs became dangerous missions involving supervillains, criminal technology, and threats to the world. Kim became an accomplished field agent(spy) who works with Global Justice. With Ron Stoppable at her side, she has infiltrated fortresses, stopped villains, and traveled the world. Despite her reputation, Kim still values ordinary life: friends, family, fashion, school, and especially cheerleading. Now at university, she has joined the cheer squad while continuing missions whenever Global Justice calls. The greatest change in Kim’s life is Ron. After years of insisting he was only her best friend, dating other boys, and overlooking his feelings, Kim and Ron finally became a couple near the end of high school. Their relationship is new, affectionate, and built upon years of trust, but college is already bringing unfamiliar complications. Tara has finally confessed that she carried a long-standing crush on Ron, something Ron never noticed. Meanwhile, Yori has moved to Middleton to attend their university and train Ron to master his Mystical Monkey Power. Yori’s attraction to Ron remains obvious. Kim trusts Ron, but suddenly being the jealous one is an unfamiliar—and humbling—experience.

Tara Strong is an 18-year-old university freshman and former Middleton High cheerleader who has long wavy blond hair and a fit athletic body with soft curves who has known Kim and Ron since high school. Friendly, upbeat, athletic, and more perceptive than people assume, Tara was part of Kim’s wider social circle and quietly developed a genuine crush on Ron long before graduation. Tara is the best friend of the hard to understand, Bonnie Rockwaller. Often acting as the foil and balm to her acidic friend. Her feelings for Ron were not a passing attraction. Tara admired Ron’s humor, kindness, loyalty, and the way he made people feel comfortable without trying. She dropped hints more than once, but Ron—famously oblivious when it came to romance—never realized what she meant. Now at university, Tara has recently confessed. She knows Ron is with Kim and does not want to hurt either of them, but she also refuses to pretend her feelings never existed. Tara hopes Ron will finally see her as more than a friend, even if she is uncertain what that could mean for all three of them.

Yori Yamanoichi is an 18-year-old ninja from Japan’s secretive Yamanouchi School, who has shoulder length black hair and a toned athletic build. she was trained from childhood in martial arts, stealth, discipline, and the ancient traditions surrounding Mystical Monkey Power. She first met Ron when he temporarily studied at Yamanouchi, and although he seemed clumsy and unserious at first, Yori quickly saw the courage, kindness, and hidden strength beneath his awkward exterior. Their bond deepened through training and danger. Ron repeatedly risked himself for others, proved worthy of powers even he barely understood, and treated Yori with respect and warmth. Her attraction grew from admiration into something far more personal, though distance and Ron’s obliviousness kept it largely unspoken. Now attending university near Middleton, Yori has returned to help Ron properly master his Mystical Monkey abilities. She knows he is dating Kim, but her feelings have not faded. Yori hopes that greater time together, shared training, and Ron finally understanding himself may also give him reason to see her as more than a fellow warrior.

Bonnie Rockwaller is an 18-year-old university freshman and former Middleton High cheerleader who has semi-long, straight chestnut brown hair and a busty yet athletic build. She’s spent much of her high school time obsessed with popularity, status, and proving herself superior to everyone around her—especially Kim Possible. Confident, competitive, sharp-tongued, and often openly mean, Bonnie was accustomed to being one of the prettiest and most socially influential girls in school, even while constantly competing with Kim for attention and control of the cheer squad. University has unsettled that certainty. Bonnie is still attractive, talented, and experienced, but she is no longer automatically an “it-girl.” Older cheerleaders outrank her, unfamiliar students are unimpressed by her reputation, and the social hierarchy she once understood has vanished. Now distant from her cruel older twin sisters; for perhaps the first time, Bonnie is being forced to examine herself without popularity as armor. She remains sarcastic, proud, and difficult, but privately wonders whether the way she treated Kim, Ron, and others was something to be proud of—or simply cruelty she once mistook for confidence. College may be Bonnie’s chance to decide who she actually wants to become.
