Main Cast

    K.C. Cooper 
Actor: Zendaya
The protagonist of the series, the oldest child of Craig and Kira Cooper, and recently recruited Teenage spy.

  • The Ace: K.C's an awesome spy, brilliant at school subjects, and in brilliant physical shape. She's also very good at sports.
  • Action Girl: K.C's described as having a black belt in Karate and it certainly shows, regularly getting into fights with enemy agents. This doesn't mean she can't be overpowered though.
  • Broken Ace: She really struggles with talking to guys she is attracted to, and can't take a good picture.
  • Can Not Tell A Lie: Ironically for her profession, while K.C.'s fine while lying undercover, she really struggles with lying to people outside of missions, especially her best friend (and even she's not that stupid). In the Halloween Episode, she explains why this is the case—she's not good with others as herself, especially when it comes to making up stories.
  • Dance Battler: A lot of her combat relies on her natural agility and flexibility.
  • Deadpan Snarker: Has her moments.
  • Expy: Of Raven Baxter and Kim Possible, though emulates the former much more.
  • Genius Bruiser: K.C. is mostly a fighter; however, she's acknowledged to be very cunning and resourceful on several occasions. She's also apparently brilliant at mathematics.
  • Granola Girl: K.C. is the only member of her family who does not eat meat. This is because Zendaya herself is vegetarian.
  • Huge School Girl: Although this applies to any character played by Zendaya, K.C. is sixteen and around six foot tall.
  • Master of Disguise: Regularly has to wear disguises as part of being undercover on missions. While this applies to her whole family, K.C. does it the most.
  • Muscles Are Meaningless: Averted. K.C.'s combat relies mostly on skill, agility and speed; and while not physically weak in any sense of the word, her thin frame means her overall strength is limited. Really, her biggest weakness is she's not as strong as some of her opponents, and can be overpowered if they manage to get hold of her.
  • Overly Long Name: Her full name is Katrina Charlotte Coretta Scott-King Cooper.
  • Sassy Black Woman: Downplayed. She's normally more friendly and accommodating; however, when annoyed or frustrated, she starts dishing out sass.
  • She's Got Legs: Though she doesn't show them off to often.
  • Statuesque Stunner: K.C. is acknowledged inverse to be very attractive on multiple occasions, and is around six foot tall.
  • Teen Super Spy: A point in the series is she's the first on in the organisation, this despite her family being spies for at least two generations. Though after that, it's clear they let others join.
  • Took a Level in Jerkass: Just imply that she is not perfect. She will either believe you're evil or wish to harm you behind your back if you're not.
  • Tomboy and Girly Girl: K.C. is the tomboy to Marisa's girly girl. Of the two, K.C. normally dresses more masculine (shirts, trousers) and is less interested in stereotypically girly things. She quite enjoys sports, and takes little interest in dressing up.
  • Wake Up, Go to School, Save the World

    Ernie Cooper 
Actor: Kamil McFadden

The younger brother of K.C. Ernie's a stereotypical nerd, but he is also very good with technology.

  • Butt-Monkey: Ernie commonly fulfills this role, as a lot of things go wrong for him.
  • Black and Nerdy: Ernie is a very big nerd, and like his family he is black. However, he is also apparently the only nerd in his entire family.
  • Lovable Nerd: His nerdy dorkiness can be seen as adorable. Also, it's hard not to feel sorry for him considering how poorly he's treated by the rest of his family, at least sometimes.
  • Mission Control: Ernie normally takes this role on missions, staying behind in the van to coordinate the others.
  • Nerd: Ernie is a pretty big nerd; he loves playing with computers and video games, hates sports and is very socially awkward.
  • Non-Action Guy: Standing out from his family, Ernie possesses no combat skills (or many physical skills); however, he will occasionally help out on missions, and participates more in missions that are more cerebral. In one episode, he participates in a mission with K.C. to go undercover as recruits in an all-boys cadet academy. Then he tried to go on a mission that involved subtlety; though thanks to his clumsiness, he botched that up.
  • No Respect Guy: Often feels like this, not without justification (his parents did kind of forget him when they came back from their vacation).
  • Playful Hacker: His computer skills often help out on missions (or sometimes just to help his family). However, he is pretty harmless.
  • Real Men Cook: When he takes over the culinary duties, he becomes a gourmet chef in one day despite having no prior experience. Might be justified that he learned these skills from his father.
  • Teen Genius: Ernie's a genius with technology, especially computers.
  • The Smart Guy: Of the group, Ernie is the best with technology and gadgets.
  • The Un-Favourite: It's clear his parents prefer K.C. But most of the time he doesn't seem to mind. Whenever his dad tries to bond with him, it's quite awkward for both of them.

     Judy Cooper 
Actor: Trinitee Stokes

K.C.'s younger sister who is a robot.

Actor: Veronica Dunne

K.C.'s best friend.

  • Brainless Beauty: Marisa is very pretty, but is also not the brightest.
  • Book Dumb: Marisa really isn't good at academics.
  • Dumb Blonde: Marisa isn't the brightest spark and is a blonde. However, Photo Bombed makes it clear she's not THAT stupid, because she figured out exactly why Ernie sneaked into her room, and in some instances, can easily tell when KC is hiding something or trying to fool her. This gets Downplayed later on, by placing more emphasis on her being The Social Expert.
  • Expy: Is similar to Chelsea Daniels, except Marisa is somewhat vain.
  • Jerk with a Heart of Gold: Downplayed. It's mentioned Marisa gets in trouble a lot and doesn't really care for school. But apart from this, she's a good and loyal friend, and is normally quite friendly towards others.
  • Secret Keeper: Following "Photo Bombed" Marisa knows K.C. and her family are spies, but keeps quiet to avoid getting K.C. in trouble and herself mind wiped. Only Ernie is aware Marissa knows their secret.
  • Spoiled Brat: Whenever she doesn't get what she wants, she turns her back on K.C. Comes to a head in season 3 when she stops talking to K.C. for not recommending her to the Organization and refuses her apology because she still didn't get what she wanted.
  • Tomboy and Girly Girl: Is the girly girl to K.C.'s tomboy. Of the two, she dresses much more femininely and has more feminine interests, such as spending a lot of time chasing cute boys and wanting to join the cheerleaders.
  • Token White: Only member of the main cast who is white.

     Kira Cooper 
Actor: Tammy Townsend
K.C. and Ernie's mother.

  • Action Mom: Kira, being a mother of two, has not affected her spy career or ability to fight in the slightest.
  • Lethal Chef: Downplayed, but her culinary skills aren't that remarkable.
  • Mama Bear: If her children are in danger, they won't be when Kira arrives.

    Craig Cooper 
Actor: Kadeem Hardison

  • Action Dad: Just because he's a part-time stay-at-home father doesn't mean his spy skills should be underestimated.
  • Bumbling Dad: His children and wife tend not to take him seriously.
  • Beware the Silly Ones: When it comes to crunch time, his opponents are going to end up being the ones who get crunched.
  • Papa Wolf: He's significantly overprotective of his children. And has the unarmed combat skills to prove it.
  • Real Men Cook: It is mentioned that Craig takes particular care in preparing meals, a bag lunch for his children takes over an hour to prepare. Another episode mentions an interest in preparing and eating gourmet cuisine.

The Other Side

     Richard Martin 
Actor: Rick Fox
The head of The Other Side, and father of Abby Martin.

  • Battle Couple: With Erica.
  • Big Bad Duumvirate: Of Season 2 with Erica.
  • Greater-Scope Villain: As the head of the Other Side, all agents within the organization serve under him, making him indirectly responsible for the majority of the conflicts that occur over the course of the series.
  • Walking Spoiler: Impossible to talk about him without revealing he's the head of the Other Side, and that his daughter is Abby.

     Abby Martin 
Actor: Kara Royster
K.C.'s cousin, one of the Other Side's primary agents, and Richard Martin and Erica King's daughter.

  • Bitch in Sheep's Clothing: Acts as a sweet orphaned girl who wants to see her mother, Erica, again, while her true intention is to reactivate her as an agent of the Other Side, using K.C. and Kira to locate her.
  • Daddy's Little Villain: Kinda obvious, given that her father is the Other Side's leader.
  • Dark Is Evil: Often wears black, which is justified, given that she's an evil spy.
  • Deadpan Snarker: Often trades insults with K.C.
  • The Dragon: To her parents.
  • Evil All Along
  • Foil/Evil Counterpart: Serves as one to K.C.; both are execeptionally-skilled agents of the organizations they work for, but while K.C. was raised by love from both parents and was taught core values and morals, Abby was raised by her evil father, and became a cold-hearted individual, and was abandoned by her mother. K.C. is terrible at lying directly, while Abby can manipulate and deceive many people to further her goals.
  • Jerkass: Not hard to call her this.
  • Like Mother, Like Daughter: Lampshaded in Accidents Will Happen and Family Feud.
  • Manipulative Bitch: See Bitch In Sheep's Clothing above.
  • Sadist: Ran Darrien over with a car, for no reason but to intimidate and cause K.C. to break up with him for his safety.
  • Walking Spoiler: For similar reasons as her parents, as talking about her in-depth reveals her to be one of Season 2's main antagonists.


A deadly, determined, extremely capable assassin for the Other Side, who has a tendency to talk to herself every now and again.

  • A Wolf in Sheep's Clothing: After being temporarily paralyzed in the fight with KC, Sheena fakes her identity to get Kira, Craig, and Judy's help. She then reveals herself to be the enemy after they help her find KC, Ernie, Marisa, and Zoe.
  • Big Entrance: The second that curtain opens, KC's, Ernie's and Marisa's eyes immediately go to her.
  • Inadvertent Entrance Cue: After the toilet randomly flushes in the safe house they're in, Ernie questions who it could be if they (Ernie, KC and Marisa) are all out there. KC says, "I bet it's your girlfriend from Kansas here to eliminate us." and boom.
  • Laughably Evil: As Sheena's talking to herself personality trait is played for laughs, naturally she falls into this as a result.
  • Psycho for Hire: Sheena seems to invoke this trope herself within the episode: "But I really don't like putting things together as much as I like taking them apart!"
  • Shifting Voice of Madness: Naturally.
  • Walking Spoiler: If you know going into the episode that she's the villain, the twist of the episode is completely ruined.

How well does it match the trope?
