* CloudCuckoolander

* CharacterTics: His eye twitches whenever there's trouble. Though it was only shown in the pilot episode.
* CloudCuckoolander
* MommasBoy
** On the other hand, there's literally no proof his mother actually exists beyond things Chris says. Kenan himself states that he's never met her and Chris's house contains no photos of her, despite them living together. Almost like a lampshade, Chris's fish is called "Norman" ala a certain famous serial killer who also imagined his mother's continued life..
** There was ''one'' episode with some proof: he puts Kenan in charge of the store because he has to take his mother to get her feet scraped. He later shows up with the bag of "foot dust."
* NoodleIncident: He has a boatload of them, all involving his [[HeWhoMustNotBeSeen mother]].

This guy has been ''tumbled down the stairs'', ''hit in traffic'', ''smashed by a rock'', ''shoved out of a window'', and even suffering a ''concussion'' while jumping out of the window to chase [[LethallyStupid Kel]] in all ''one day'', and somehow this guy is ''still alive''.
* JerkassHasAPoint: His animosity towards Kel is extremely understandable since he often injures him.
* JerkWithAHeartOfGold: He is far from an AbusiveParent, but is just very impatient with [[{{Schemer}} Kenan]], and especially [[LethallyStupid Kel]]. He does try to be protective towards Kenan (especially in TheMovie).
* KickTheDog: Roger telling Kel "he was ''never'' his friend."
* LaserGuidedKarma: He taunts Kel along with Kenan for not being able to drink orange soda for a week, and Kel (though accidentally) throws a ''filled'' orange soda bottle ''at his head''.
