Today, Marvel shared our first look at their epic series Inhumans vs. X-Men.

Two super-powered races clash this December as Mutantkind and Inhumanity collide with the fates of their species at stake! Prepare for battle as Charles Soule (Uncanny Inhumans), Jeff Lemire (Extraordinary X-Men) and Leinil Yu (Secret Invasion) bring you the two groups to war in the explosive series.

The Terrigen Mists roll across the planet, birthing new Inhumans and poisoning the planet’s Mutants. Tensions are about to reach their boiling point as time is running out! Terrigen is on the verge of reaching a saturation point in the Earth’s atmosphere. The ultimatum is clear – the X-Men must destroy the mists, or risk Earth becoming forever poisonous to their kind. With their backs to the wall, it’s win now…or go extinct. Only one problem – the Inhumans won’t go down without a fight! And they’re calling in everyone!

Time for these two Marvel mainstays to put it all on the line as they go head to head. Neither can survive while the other persists. Who will be left standing? The ultimate war for survival kicks off on December 14th in Inhumans vs. X-Men #1.
