About

Very little is known about Leroy Jenkins, the notorious Griefer who nearly destroyed the World... of Warcraft, some time ago. He was defeated by four brave warriors (and Stan's Dad) and peace was restored. After a long absence, he joined a group of internet trolls aiming to stop the Danish from exposing their online identities, joining forces with the legendary troll Skankhunt42.

Close Friends

Jenkins doesn't have a life, and thus primarily associates with other internet trolls around Colorado to defend their means of existence.

Rivals

The four brave boys (and Stan's Dad) who defeated him are probably his most notrious rivals, but these days Jenkins also works against the Danish, who seek to eradicate trolls.

Trivia

The name Leroy Jenkins is a meme in the World of Warcraft community. It is never used for this character in the show, but was given in the South Park Studios FAQ around the time of the episode's airdate.
It isn't visible in his first few appearances, but in "Fort Collins", we learn he has a ponytail.
