Xavier welcomes two newcomers: Logan/Wolverine, a solitary fighting machine who possesses amazing healing powers, retractable adamantium claws and an animal-like fury; and Rogue, an alienated teenage girl who can absorb the powers and memories of anyone she touches. As Wolverine and Rogue adjust to life among their "kind," the X-Men find themselves locked in a physical and philosophical battle with the Professor's former colleague and friend, Erik Lehnsherr a.k.a. Magneto. One of the world's most powerful mutants, Magneto has turned his back on society, believing that humans and mutants can never coexist, and that mutants are the rightful heirs to the future. He and his evil Brotherhood--the mammoth Sabretooth, the metamorph Mystique and the near-sighted, far jumping Toad--will stop at nothing to ensure that future, even if it threatens the very existence of mankind... or mutantkind.
