Pickman

Pickman is a serial killer and self-described artist living in Pickman Gallery in the Commonwealth.

Background
Pickman is a man with a strong dislike for raiders, killing anyone who wanders into his home. While generally presenting himself as collected and polite, he is actually extremely disturbed, casually mentioning his hobby of collecting the raiders' heads.

The Sole Survivor first meets Pickman deep within the tunnels of Pickman Gallery while he is being attacked by Slab, a raider who wants to take revenge on Pickman for killing his men.

Other interactions
If the Sole Survivor kills Slab and the two raiders on either side of Pickman and then speaks to him after, they are rewarded with Pickman's key, which opens a safe on the ground floor of the Gallery, containing Pickman's Blade and Pickman's thank you note. If the Sole Survivor opts to kill him or let the raiders kill him, his corpse can still be looted, but the note will not be in the safe.

Appearances
Pickman appears only in Fallout 4.
