In the Marvel Universe, mutants are humans who are born with natural superhuman abilities, and most normal humans fear and hate them. The X-Men are a paramilitary group of mutants that fights for peace and equality between normal humans and mutants. They are led by Charles Xavier, also known as Professor X, a powerful telepath. Professor X runs a school for mutant children out of his mansion in Westchester, New York, which secretly is also the headquarters of the X-Men. The X-Men's archenemy is Magneto, a mutant with magnetic abilities who leads a mutant supremacist group known as the Brotherhood of Mutants.
