Deputy Weld

Deputy Weld is a Protectron robot that guards the gate of Megaton. He appears to have been programmed to have a somewhat 'western' personality, as when the player speaks to him he refers to them as "partner".

He is also known to ally himself with the player and fight against any hostile creatures that approach the city gate.
