Mechanist (Fallout 4)

The Mechanist, actually Mayor Murphy in disguise, was a fictional villain in the Fallout world, being an antagonist to the Silver Shroud.

Background
In the Silver Shroud radio series, the Mechanist, actually Mayor Murphy of Boston, believed that humanity was weak and should be replaced by his own robot army. Included in this army was the mobster Fat Fahy and a group of mob-bots. Wishing to take down the crimefighter Silver Shroud, Mayor Murphy created a robot version of himself and set the robot to meet with Fat Fahy and die, in order to lure in Silver Shroud and the Mistress of Mystery. When the two investigated the mayor's death, they discovered that he and his accomplices were robots serving the Mechanist.

When they arrived at the Mechanist's liar within a warehouse, he successfully captured the both of them and prepared to kill them. However, the two crimefighters were freed by one of the Mechanist's own creation, a mob-bot angry at him, and did battle with the Mechanist's robot army. After destroying his robots, the Mechanist attempted to kill the Silver Shroud with the Shroud's own submachine gun. However, the Silver Shroud had made it so the weapon was incapable of hurting him, resulting in the bullets bouncing off of him and hitting the Mechanist, fatally wounding him. As he died, the Silver Shroud unmasked him, revealing his true identity and his entire ruse.
