Michael Masters

 is a ghoul residing in Warrington Station in the year 2277.

Background
Before the Great War, Michael was a scientist. He claims that they were making real scientific progress, but people got hurt while doing so. It can be inferred that he worked in some variety of weapons research program, as he states that "Karma's a bitch" after talking about the bombs falling.

He also says he used to vacation in Tenpenny Tower.

Interactions with the player character
Upon first meeting Michael he'll ask you who you are trying to make you go back the way you came. If you complete the Tenpenny Tower quest by convincing the other residents to let the ghouls in, Michael will have a shop and will sell you random guns, ammo, and other items with a nice discount.

Appearances
 only appears in Fallout 3.

Quotes

 * "Karma's a real bitch, you'd be wise to remember that."
 * "I don't want to have to waste bullets on your sorry hide."
 * "I wasn't always like this. I was a goddamn scientist. We were doing great things. Amazing things!"
 * "Go live your life, kid."

Bugs

 * If you decide to kill all the residents and let the ghouls move in, when you walk into tenpenny tower you may see him walk towards the door and then walk out. If you follow him he will walk towards the main exit then disappear when he gets to the potted plants, and you will hear the sound that happens when you go through a grate. If you search Warrington station he will be nowhere to be found.


 * If you kill Michael Masters before you end the Tennpeny Tower quest with good karma, you can't buy from Lydia Montenegro's shop. Meaning, you can't buy anything for your Tenpenny Tower Suite.


 * May be hostile for no apparent reason upon first meeting or inside Tenpenny Tower. Only known solution is to load a previous save. (Confirmed on all Platforms)


 * If you buy the Dart Gun schematics from Lydia, before you let the ghouls into tenpenny tower, Michael Masters will sell an additional copy.
