Peter Mullen, formerly known as Leroy Jenkins, is a shy looking boy who first appears in "Mystery of the Urinal Deuce".


In "Mystery of the Urinal Deuce", Peter does a "Show and Tell" about his pet frog. He makes a reappearance in "The List", ranking #6 on the girls' fake list, as Leroy Jenkins. In "Cash For Gold", where he was seen on the playground selling jewelry to Eric Cartman. In "Informative Murder Porn", he gives a school report on "murder porn".


Peter has brown hair in separated bangs, freckles, and large black-rimmed glasses. He wears a blue T-shirt with a red octopus on it and grey pants.


Peter Mullen is seen as a stereotypical geek/nerd. He has interests that are seen as odd to others, displays a high sense of intelligence, and is socially awkward. His most impactful contribution to the show is his presentation on "murder porn" in "Informative Murder Porn", where he convinces the student body that it was a bad thing. Despite these characteristics, it appears that the girls of South Park Elementary like him, as they ranked him sixth on the real attractiveness list.


  • In "T.M.I.", he was listed by the school as Leroy Jenkins, a reference to the famous internet meme featuring a World of Warcraft character of the same name.
  • In South Park: The Stick of Truth, his name is given as Leroy Mullens, combining his original and later names. He can be seen in detention and perched above the News Office. He calls himself a goblin waiting to steal gold.
    • In earlier builds of the game, his name was Reginald.
