The life of Erik Lensherr, the mutant known as Magneto, changed when his friend Charles Xavier sacrificed himself to save Erik and was killed by Legion, Xavier’s psychotic son that traveled back in time to eliminate Erik. His death changed Lensherr, that swore to continue Xavier’s dream of a world where mutants and humans could coexist peacefully. But the mutant known as Apocalypse anticipated his attack on this reality dominating the world, and to face him, Magneto created a team of mutants to defend those who couldn’t protect themselves, and to fight against Apocalypse and his legion of mutant followers, thus creating on that reality the group of heroes known as the X-Men. Magneto provided the place for young mutants to learn how to use their powers and to fight for genetic equality, building their base of operations hidden in Mount Wundagore. Over time, he and the hero Rogue started a romance, got married, and had a son named Charles.
In this alternate reality, the only person aware of how history has changed is the mutant Bishop, and only he can stop the emergence of the Age of Apocalypse…More than just a story arc, “Age of Apocalypse” was a big Marvel event, of great importance for the comics chronology and praised by fans to this very day.
