The Master is the main villain and final boss of the post-apocalyptic RPG adventure game Fallout. He is a disgusting mass of mutated flesh infused with the computer system of the underground vault in which he resides. The Master is the leader of an army of "Super Mutants" and wants to replace the (few remaining) "pure" humans that hadn't suffered mutation with his new race of mutants, believing that, unlike humans, they will never fight amongst each other. A notable feature of The Master is that his "voice" is pieced-together from the different voices of people that he's absorbed through the years.
