Kenan Rockmore is Kel's best friend. Kenan is relatively intelligent, but he rarely accomplishes any schoolwork. His birthday is on July 10, 1980. but he spends his time plotting schemes (such as transforming the grocery shop at which he works into a nightclub, or telling everybody that Kel has extra-sensory perception). Though good-natured, he frequently angers his parents and boss. A trait that Kenan shares with Kel is that when someone uttered a nonsense word, the duo would repeat the word confusingly. In one episode, Kenan said the word huckleberry. This prompted Chris and Kel to repeat the word confusingly. His catchphrase is "WHYYYYYY!" and he usually yells it when Kel does something wrong.
Kel Kimble is the dim-witted and incredibly clumsy best friend of Kenan Rockmore. His full name is Kelvin "Kel" Johari Kimble his full name is never mentioned on the show at all but he is the only child of Mr and Mrs. Kimble. His birthday is on February 2, 1980. He is actually quite intelligent as witnessed by his SAT score but he acts stupid to not do any work. He loves orange soda(which he professes by talking in the third person "Who loves orange soda? K-K-K-Kel loves orange soda. Is it true? Mm-hmm! I do, I do, I do-ooh!" and never pays for the soda he drinks from Rigby's which annoys Chris. Since Kel's parents are rich, busy scientists, he often visits and stays in Kenan's home to keep him company. He might resist following Kenan's schemes at first, but ultimately he is included anyway and Kel somehow always ruins them. Kel is also an incredible painter, and is often seen wearing a hat. He is scared of pancakes, butterflies, Brazil, waffles and monkeys. His catchphrase is "AWWWW, HERE IT GOES!" which he says at the end of the beginning and end of the stage sequences and he has another catchphrase which is "Ohhh" he uses this catchphrase when he discovers something by Kenan telling him. Kel hates Kyra but in different ways. Sometimes he likes her but sometimes he doesn't like her.
Chris Potter is Kenan's boss and the owner of the local grocery store, Rigby's. His birthday is on April 16, 1960. he lives with his mom (or the other way around) and has frequent nightmares of being chased by a giant rabbit, as well as a phobia of sandwiches. Chris is always sometimes caught in the middle of some of Kenan's schemes and may sometimes get hurt. One of his catchphrases is "I have a radio in my car!". Chris usually uses obscure words. He has a brother named Rick
Kyra Rockmore is Kenan's younger sister. Her birthday is on November 8, 1987. But her biggest mission is telling on her brother Kenan, but she has devoted herself to Kel, having a major crush on him. Kel being aware of Kyra's crush on him, tries to get far away as possible from her. For most of seasons three and four, Kyra did not appear, even in scenes showing the whole family; she did, however, appear in the series' finale TV movie. She often interrupts Kenan by saying "I was talking to Kel!".
Roger Rockmore is Kenan and Kyra's father. He works at the local airport as an air traffic controller, and is the only Rockmore who doesn't appear to like Kel. This is mostly due to the fact that Kel often makes a sarcastic remark about Roger's baldness and tends to damage the Rockmore house during his visits. He is also short-tempered, and will punish Kenan if needed. He also hates his boss Mr. Dawson.
Sheryl Rockmore is Kenan and Kyra's mother. Sheryl is kind and always seems to know what schemes Kenan and Kel are up to. She is also much more patient with Kel than her husband. Sheryl is much more of a listener than a punisher; she'd rather talk out problems with Kenan than punish him, though she has demonstrated her anger in several episodes.
Sharla was introduced as a new employee at Rigby's at the start of season three. In the show, Chris hired her because he felt Kenan needed more help around the store. A recurring joke in episodes is she and Kenan would insult each other. While there, Sharla started to develop a crush on Kenan, and he developed a crush on her. However, they only both realized it during a prom at their high school.
Marc was introduced in season three as a new neighbor of Kenan. Kenan finds him annoying while Kel is buddies with him, much to Kenan's greater annoyance. He was an avid collector of watches, and excelled at spelling, at times during conversation never mentioning a word by its name, but spelling it out. His name is also a palindrome.
Mrs. Ethel Quagmire was introduced in season one as an elderly customer at Rigby's. The character provided some light relief to the show during serious events, and has also "beaten up" Chris Potter on several occasions. In a season one episode, Chris thought that Quagmire stole a tin of peanuts; following this, she "sucker-punched" him and called him a "Weasel". In the season two episode The Lottery, she entered the store hoping to purchase a lottery ticket, but Potter said the store was closing. She then held him against the door, again calling him a "Weasel". The character disappeared in season three, but she returned in season four. She was played by Doreen Weese.
Principal Dimly (Hersha Parady)

In the episode "Corporate Kenan", there is an employee with a similar personality, he might be her father, uncle, or even cousin.
