Pipboy (character)

PIPBoy is a joke character that could be encountered by the warrior. He may join the squad and fight alongside normal members. It means he becomes a member of the Midwestern Brotherhood of Steel, however, they, while use him as a warrior, do not count him even as initiate.

It could be assumed that PIPBoy is some sort of bio-robot (or android), that escaped a pre-war theme park, or just was created for promotional reasons. Thus, he wandered the wasteland before the warrior finds him. The fact the Brotherhood don't see him as a member could be explained by the fact he is a strange, never-seen-before creation, and they merely watch over him.

Availability
PIPBoy becomes available after you find him in a special PIPBoy encounter. He could join the group if you have less than 5 members. He will go away and appear in recruits pool if you have 5 members. If you have 6 members, he will do nothing.

Appearances
PIPBoy as a recruit (actually, VaultBoy) appears only in Fallout Tactics. As a mascot of VaultTec, he appears in all games.
