The Master of Magnetism is back, and he'll do whatever it takes to secure his goal: a safe haven for Homo superior! As Magneto's actions threaten the globe, the X-Men find themselves in the middle of a war for the future of mutantkind! But what is Magneto's connection to their teammate Joseph, and what will be his fate? A new era begins for the island nation of Genosha as Wolverine seeks vengeance, the unstoppable Juggernaut crashes through dimensions, the X-Men find themselves on a world of doppelgangers and the Red Skull strikes! But when Magneto claims his throne at last, will Rogue and Quicksilver stand with him...against an entire world?
