PIPBoy (character)

PIPBoy is an actual person version of Vault Boy who could be encountered by the Warrior as a joke character. He may join the Eastern Brotherhood of Steel and fight as a squad member, but is not considered an official member by the Brotherhood due to not being a normal person (which in this case is to say he does not fit into any known species of the wasteland).

Background
While the existence of Vault Boy in the Fallout world as an actual person is obviously meant as a joke and easter egg and not to be taken seriously, the most likely canonical explanation of this character is that he was some sort of robot or artificial human created by Vault-Tec who wandered off into the wasteland after the war. 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 study him or use as a military device.

Availability

 * PIPBoy is added to the recruitment pool after meeting him in the Pipboy special encounter. It's possible to bypass the level requirement by having a spare spot in the party, as he will force-join.

Recruit evaluation
He has a Perk Rate of 3 yet at the time he is discovered, he is level 8 with 3 perks. This is likely due to the fact that PIPBoy cannot change stance; by granting Flexible as a freebie, the player is protected from later wasting a gained perk on it.

He moves considerably slower than other characters when not in turn-based mode.

He has no biographical text in the character screen or in the recruitment pool.

Appearances
PIPBoy/Vault Boy as a person appears only in Fallout Tactics: Brotherhood of Steel.
