Mister Crowley

Mister Crowley is a ghoul resident of the Underworld in 2277.

Background
Mister Crowley is as bitter a ghoul as you could find. He was transformed 10 years ago due to an extreme exposure of radiation that should have killed him. He once lived at Rivet City, but the bias and hatred he experienced there forced him to move on. Crowley discovered Underworld and has taken up permanent residence, but remains resentful of the harsh treatment he received from humans. He presents the Lone Wanderer with a complex revenge plan that he wants you to carry out. Mister Crowley spends most of his time in the Ninth Circle, drinking heavily.

Crowley and four other mercenaries - Dave, Jeff Strayer, Dukov, and Tara - were sent to Fort Constantine by Allistair Tenpenny to retrieve a rare weapon. During the mission, Crowley was locked in a room full of feral ghouls by Dukov, who wanted to increase his own share of the pay. Crowley survived the imprisonment and harbors resentment toward those who left him behind.

Daily schedule
Mister Crowley can usually be found in either the Ninth Circle or in his bed at Carol's Place in Underworld. He usually sleeps until 12 p.m.

Quests

 * You Gotta Shoot 'Em In The Head: Mister Crowley gives you a list of four targets he wants dead.

Effects of player's actions

 * If the Lone Wanderer retrieves the keys detailed in his quest, he/she can go to Fort Constantine and take the T-51b Power-Armor. Mister Crowley won't be too happy with this and only respond with, "You stole what was rightfully mine. Get lost.", without an option to give the suit to him. He will say the same thing if the Lone Wanderer pickpockets the keys from him after giving them to him.
 * If the Lone Wanderer hands Crowley the keys and later travels to the Fort Constantine's Bomb Storage section he will be inside wearing the armor and thank the Lone Wanderer for the keys.
 * If the Lone Wanderer kills Crowley at any time, he/she will no longer be able to collect caps for this quest. The Underworld will turn hostile for 72 in-game hours if the Lone Wanderer is detected in this act.

Appearances
Mister Crowley only appears in Fallout 3.

Behind the scenes

 * Mr. Crowley is possibly named after Aleister Crowley, a famous British writer and occultist. (Aleister Crowley's first name is often misspelled Alistair or Allistair, as in Allistair Tenpenny, the arch-nemesis of Underworld's Mr. Crowley.)
 * The Fallout 3 Official Game Guide uses the lyrics to Ozzy Osbourne's song Mr Crowley in its walkthrough of You Gotta Shoot 'em in the Head.

Bugs

 * Occasionally, Crowley will go into a bout of slow motion sprinting, running at nearly half speed but with full striding animation. He will resume normal movement upon his next combat encounter.
 * Crowley may deliver the "You stole what was rightfully mine!" line if the Lone Wanderer acquires the winterized T-51b power armor helmet from the Anchorage simulation.
 * With Broken Steel installed: After getting the T-51b power armor and T-51b power helmet from Fort Constantine by unlocking all the doors, then finishing the You Gotta Shoot 'Em In The Head quest by giving Crowley the keys, and fast traveling back to snatch the armor before Crowley finds out, Crowley has been encountered still friendly in the Presidential Metro, just inside the doors from M.A.R.Go.T., during the Who Dares Wins quest.
 * Occasionally, Mr. Crowley will not appear in the Underworld.
 * If the Lone Wanderer gives Mr. Crowley the keys, pickpockets the keys back and goes to Fort Constantine to get both his reward and the T-51b Power-Armor without having to kill him, he will disappear from the game.
 * If the Lone Wanderer hands Crowley the keys and manages to obtain "his" power armor from Fort Constantine without these keys, he might show up later and attempt to kill him/her.
