The Nuzlocke Challenge is an self imposed difficulty run for Pokémon games. Originating from the author(known in the comic as "Ruby" and as Nuzlocke)'s comics posted on 4chan's /v/ board, the Nuzlocke Challenge has become a popular trend and has been attempted by many other fans of the Pokémon series of games. The name comes from a Nuzleaf from the comic bearing a likeness to John Locke from the television series Lost. The name was dubbed by the users of /v/ that were the initial audience of the comic.
