Dean Domino

 was a pre-war lounge singer, now ghoulified and trapped in Sierra Madre in 2281.

Background
Prior to the Great War, Domino was a very famous lounge singer, often playing on the old Las Vegas Strip. Although he is a quick thinker, trained with pistols, explosives and knives, he is very paranoid, setting up many booby traps and secret stashes throughout the Villa - perhaps understandably, considering the Ghost People who inhabit it.

After being captured by Father Elijah at the Abandoned BoS Bunker, the Courier must work with Domino to find the treasure at the heart of the Sierra Madre casino and win their freedom. Although he is bound by the Collar, Domino appears to possess his own lust for the treasure he has waited literally hundreds of years for, and will no doubt try anything to obtain it.

Appearances
is mentioned in Fallout: New Vegas and appears in the DLC Dead Money.
