Characters: Kick Buttowski
Clarence Francis "Kick" Buttowski
Voiced by: Charlie Schlatter
- Acrofatic: He's definitely not as huge as his friend Gunther, but he is drawn pudgy. Yet, he does manage some amazing stunts and maneuvers.
- Awesome McCoolname: Well, Awesome McCool Nickname.
- Betty and Veronica: The Archie to Jackie's Betty and Kendall's Veronica.
- Brilliant but Lazy: There a few episodes that show that Kick is actually smart. In "Morning Rush", he did a months worth of homework in one night. He also has an innate grasp of the angles and forces involved in all of his stunts, even if he may not fully realize that those are actually math.
- Catch Phrase: "Biscuits", when things look ominous.
- Cool Helmet
- Deadpan Snarker
- Follow in My Footsteps: Both Kick's mother and Kick's grandfather (though we're not sure if it's maternal or paternal grandfather) were both daredevils in their youth as well. And despite the parental grumping about being careful, they're both proud of Kick.
- Heterosexual Life-Partners: With Gunther.
- I Call It "Vera": His skateboard is named Ol' Blue, and his BMX bike, Bonecrusher. And anyone who lives in Mellowbrook would probably attest that although these are sports equipment, they are weaponized when Kick uses them.
- Identical Grandson: Kick looks exactly like his grandpa did when he was younger. Right down to not having a nose.
- The Leader
- Made of Iron: No matter the bone-shattering flubs from his stunts, he's always up in a short time.
- Manly Tears / Not So Stoic: As an occasional response to positive emotions.
- The Napoleon
- Never Bareheaded
- The Noseless: Lampshaded in "Wade Against the Machine" and "Garage Banned".
- Only Known by Their Nickname
- The Quiet One: He's not very quiet as anyone thinks, but his voice does sound quiet.
- The Stoic

- The Ace: In "Pinch Sitter", she shows she can sleep, clean, and do algebra at the same time.
- Badass Bookworm: Turns out to be this in “Stuck Together”.
- Belligerent Sexual Tension: With Kick.
- Bizarre Taste in Food/Trademark Favorite Food: Her favorite food is tuna surprise.
- Betty and Veronica: The Veronica to Jackie's Betty for Kick's Archie.
- Blonde, Brunette, Redhead: The Blonde to Jackie's Brunette and Scarlet's Redhead.
- Extracurricular Enthusiast
- Gasshole: A closet case example, but quite proud of it in private.
- Hidden Depths: "Hand in Hand" shows that Kendall is not only perfectly capable of keeping up with Kick in stunts, but is just a flatulent as Gunther.
- Hollywood Nerd
- Jerk with a Heart of Gold
- Lovable Alpha Bitch/Academic Alpha Bitch
- Missing Mom: Her mother never appears on the show. According to Word of God this is because her mother lives in another city, possibly meaning her parents are divorced.
- Nerds Love Tough Schoolwork: It was the snow day episode that sealed it.
- Not So Above It All
- Sympathetic Inspector Antagonist: Despite her Jerkass tendencies, she sometimes comes across as this, especially in "Pinch Sitter". It helped that Kick was being a Manipulative Bastard at the end of the episode.
- Well, Excuse Me, Princess!
- Zettai Ryouiki

Harold and Honey Buttowski
Voiced by: Brian Stepanek (Harold); Kari Wahlgren (Honey)
- Action Mom: Honey used to be quite the daredevil herself and she's still got it as shown in "Kickin' Genes".
- The Big Guy / Bumbling Dad: Harold.
- Career-Ending Injury: Honey ended her career as a speedboat stunt-woman because she tore her tendanacious ligamental flexor. Kick encourages her to try again years later, but the injury flares up at a plot appropriate moment.
- Hartman Hips: Honey.
- Parents as People: Sometimes Doting Parent, sometimes Parental Neglect.
- The Smart Girl: Honey again.
- Took a Level in Jerkass: Honey again. Her marriage with Harold is on the verge of collapsing as well, after seeing some scenes of her talking down to Harold, especially in "Brad's Room". And that's not the only time...
- Harold's not off the hook either after refusing to help rebuild his son's room in "Brad's Room".
