Mister Crowley

Mister Crowley is a resident of the Underworld who gives the player the "You Gotta Shoot 'Em in the Head" Quest. After completing this quest, should the player decide not to follow Crowley to Fort Constantine, Crowley may return to Underworld wearing the T-51b Power Armor. While he will also have the T-51b Power Helmet in his possession, he will not be wearing it.

Mister Crowley can usually be found in The Ninth Circle in the Underworld, although he rents a bed and sleeps at Carol's Place, also in Underworld.

Tasked by Allistair Tenpenny to retrieve a rare weapon, he along with five other mercenaries set off to accomplish this task. He was locked in a room full of feral ghouls by Dukov so the commission would not have to be shared. Crowley survived and harbors hatred to those who left him behind.
