BAJAR

 is a brain-in-a-jar in 2253.

Background
BAJAR: A brain-in-a-jar. If you give him a robobody, he's a pretty good scientist, though he's sometimes hard to control because he's a little loopy from being just a brain all these years.

Interactions with the player character
He can be your companion, but he can't do anything unless you put him in a robobrain body, but you can carry his jar around and ask him questions about stuff. He is not willing to join the party unless the PC has some scientific background. He won't join you if you erased the minds of the Think Tank, even to save ZAX.

Appearances
BAJAR was going to appear in Van Buren, the canceled Fallout 3 by Black Isle Studios.
