Lone wolf

From PhallaWiki

A Lone Wolf is a player who has to survive to the last day, and kill all other players for a victory. This typically means the Lone Wolf is also a vigilante, but this can vary from game to game.

A Lone Wolf is usually known as a Serial Killer, but lone wolf has become accepted slang for the role.

It is considered the hardest role for a player to receive, since odds of victory are extremely slim.

One of the few instances in which a Lone Wolf was victorious was Plutonium's A Song of Ice and Fire Phalla, in which Delroland had the role of Petyr 'Littlefinger' Baelish.
