humans, products of a Forced Evolutionary Virus
infection. They have (mostly) green skin, are immune to disease and radiation, and are blessed with exceptional strength and endurance. They also possess exceptionally long lives as well as total sterility. Super mutants were created by Richard Grey
, who, after falling into an FEV vat and being horribly mutated, called himself The Master
. In his warped state, he decided that he would have to force humanity to evolve. If everyone could be as perfect as his super mutants, there would be no more conflict. Those who could not evolve would die. The Master began seeking out uncontaminated humans from whom to create mutants and build his super mutant army.
