Kenny is most famous for dying in nearly every episode, often followed by a cry of "Oh my God! They killed Kenny! You bastards!" from his friends Stan and Kyle.
He is also well-known for never appearing except under his orange hood (although he does remove it during the movie South Park: Bigger, Longer & Uncut). Due to his hood, all of his lines are mumbled, and are usually such that they'd be censored if they weren't. He has a colorful sense of humor and a perverted mind. Kenny's lines in the South Park theme song are:
Despite these problems, Kenny is often portrayed as the hero of the group; indeed, several of his deaths have been acts of heroic self-sacrifice. Matt & Trey tried to kill him off for a year and replaced him first with Butters and then Tweek. During the 2002 Christmas episode Kenny returned after being trapped in the depths of Cartman. During the following season, he seemed to have lost his bad luck and doesn't die anymore. Unfortunately, Kenny's lucky streak ended during the 2003 Christmas episode (It's Christmas in Canada).
Kenny wears an orange parka with brown gloves.
