Kevin McCormick is Kenny's older brother. He never appears without the rest of his family or Kenny, and very little is known about him. He only has a speaking role in three episodes: "Chickenlover", "Chickenpox", and "The Poor Kid", but is often seen in the background with his brother or his family, usually at church or at Kenny's numerous funerals.
Kevin has wild, messy brown hair, with a bandage, scratch, dirt and leaves on his face. He wears gray pants and a red button-up shirt and has a set of braces. In "Quintuplets 2000" he wears a light blue suit with a green tie, however, in "Sexual Healing" he wears a black suit with dark blue tie for Kenny's funeral. His voice sounds somewhat like Bill Allen.
Kevin appears to be either a heavy drinker or mentally handicapped, as he speaks in a slow, repetitive slur when talking normally. However, he talks much more quickly and clearly when yelling. Further suggestion of mental retardation can be found in "An Elephant Makes Love to a Pig", where a boy resembling Kevin is seen on the bus for handicapped kids. Although, contradictory evidence is seen in "The Poor Kid", where his mother calls him and his father "drunk pieces of shit". Kevin seems to have violent tendencies - he tells his mother to shoot his father and later attempts to strangle his father, initiating a fight.
Kevin is Mrs. McCormick's older son. They were never seen interacting one-on-one, although, judging from the pseudo-conversation they had in "The Poor Kid", their relationship seems to be a weak one, filled with fighting. (His relationship with his mother is likely stronger there with his father).
Kevin is Stuart McCormick's older son. Judging from the events of "The Poor Kid", they do not have a good relationship. Their relationship also seems to be violent, likely when they are drunk, with Mrs. McCormick having to step in to prevent them from physically fighting each other.
Kevin is Kenny's older brother. The two were never seen interacting, so little is known about their relationship. They seem indifferent to each other's presence, completely ignoring each other. When seen together, it is usually with the rest of their family.
Kevin is Karen's older brother. The two were never seen interacting, so little is known about their relationship. Kevin seems to ignore her, however, she seems to look for him for protection, hiding behind him in various instances.
- Although the McCormicks are poor, Kevin appears to have braces.
