The Fallout PC is known as the Vault Dweller, and the Fallout 2 one as the Chosen One. The PC in Van Buren, the cancelled Fallout 3 by Black Isle, was known as the Prisoner. Player characters in Fallout Tactics and Fallout: Brotherhood of Steel were known as the Warrior and the Initiates, respectively. The player character of Fallout 3 is called the Lone Wanderer.
