Kevin McCormick

Kevin McCormick is Kenny's older brother. He virtually 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.

Appearance
Kevin has wild, messy brown hair, with a bandage, scratch, dirt and leaves on his face. He wears gray pants and a red shirt and has a set of braces. He is also seen in a tuxedo in the episode "Quintuplets 2000". His voice sounds somewhat like Bill Allen.

Personality
Kevin appears to be either a heavy drinker or mentally handicapped, as he speaks in a slow, repetitive slur when talking normally; however, when yelling, he talks much more quickly and clearly. Further evidence 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, contradictor 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.

Mrs. McCormick
Kevin is Mrs. McCormick's oldest son. They were never seen interacting one-on-one, although, judging from the psuedo-conversation they had in "The Poor Kid", their relationship seems to be a weak one, filled with fighting.

Stuart McCormick
Kevin is Stuart McCormick's oldest son. Judging from the events of "The Poor Kid", they do not have a good relationship. Their relationship also seems to be violent, with Mrs. McCormick having to step in to prevent them from physically fighting each other.

Kenny McCormick
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.

Karen McCormick
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.
