Peter Nelson made his first appearance in "Make Love, Not Warcraft". He is a co-worker and friend of Randy Marsh at the South Park Geology office. Nelson is also a member of the Cult of Cthulhu, and the Hare Club for Men. In "Broadway Bro Down", he is revealed to have a wife.
Nelson has long gray hair and glasses. He wears a green shirt, pocket protector, and brown pants. He usually wears a green shirt except when he is attending a Cthulhu cult ritual, then he has a black robe.
Nelson seems rather calm and uninterested in whatever is going on. When Randy was showing off his avatar in World of Warcraft, he casually remarked on how it was killed easily by the griefer. Even when he is interested he still acts very passive about it such as football, marijuana and blow-jobs from his wife.
