Appearances
This character is mentioned in Fallout 3 but does not make an appearance in the game. When first entering the Overseer's Control room the screen will have the blue tint and the Overseer will appear as a mirage, however this is not Vault 106's Overseer, but Vault 101's (as he's wearing a Vault 101 jumpsuit).
