Mister Crowley

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

Background
Mister Crowley is as bitter a ghoul as you'll 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 you 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 12pm.

Quests

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

Effects of player actions

 * If you keep the keys for yourself, you can go to Fort Constantine and take the T-51b Power-Armor. However, Mister Crowley won't be too happy with this. Accordingly, he will say only "You stole what was rightfully mine. Get lost." after your acquisition. He will also say the same line of dialog if the player has pickpocketed the keys from him after already given them to him.
 * If you hand him the keys and managed to obtain "his" power armor from Fort Constantine, he might show up later and attempt to kill you.
 * If you hand him the keys and later travel to Fort Constantine's Bomb Storage section (you'll have to pick a "very hard" lock to get in) he will be inside wearing the armor and thank you for the keys. You can kill him for no Karma effect and take the T-51b Power-Armor.
 * You can give him the keys, receive the reward, then pickpocket him to get the keys back and go straight to Fort Constantine, as you would if you never gave him the keys and get the T-51b Power-Armor. He then disappears.

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

 * Crowley may fall 'through' the Potomac River Bridge about two-thirds of the way across, probably due to a glitch in the programming. Crowley will continue his journey after his fall.
 * 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 player 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.
 * Crowley may get stuck on his way to or from Fort Constantine.
 * Occasionally, Mr. Crowley will not appear in Underworld.
