A "cure" has been developed for mutants, but what does this mean for the children of the atom? Worthington Labs, the developer of this cure, finds itself in the sights of one of the most powerful mutants of all time: Magneto. With a growing army, Magneto storms the lab, aiming to annihilate the source of the cure—a young, frightened mutant.
Ever-vigilant to protect the lives and freedom of mutants and humans, the X-Men stand ready to battle Magneto and anyone else who would harm the innocent. Featuring Phoenix, Juggernaut, Colossus and a host of mega-powerful mutants, the fate of Homo Superior depends on the outcome of this last battle.
