Marvel is pleased to present your first look at UNCANNY X-MEN #531 featuring the debut of new co-writer Kieron Gillen who joins the Eisner Award-winning Matt Fraction and artist Greg Land! The X-Men have fought tooth and claw to defend Utopia from invaders and now they’d do anything to get off it! An unexplained illness has broken out, depowering every mutant it infects and riddling them with horrific side effects. Wolverine? Dying of adamantium poisoning. Rockslide? Soon to be rubble. But with quarantine now in full effect, will the X-Club be able to discover the cause without help from the mainland? And just who was the harbinger of this mysterious malady? Beware because, this December, mutantkind becomes all the more endangered, only in UNCANNY X-MEN #531!
