E is for Extinction: Warzones!

Journey to a Battleworld realm inspired by one of the most celebrated X-Men eras of all! In Mutopia, mutants have shown themselves to truly be superior. But what role do the X-Men play when the world no longer hates and fears them? Ask Magneto — after all, he's the one in charge of the Xavier Institute; his team includes Quentin Quire, Beak and the Stepford Cuckoos. But not everyone is a fan of these New X-Men. Take Cyclops and his classic X-Men — Wolverine, Emma Frost and Beast. To save the life of one of their own, old will battle new! Plus: Look back at the kickoff of Grant Morrison and Frank Quitely's revolutionary NEW X-MEN revamp!
