The blockbuster final chapter of the first era of ULTIMATE X-MEN!

The world was on the brink of destruction. Countless heroes died. The X-Men are gone. The true history of the X-Gene has been revealed, and now mutants have been branded as terrorists and are being hunted as criminals. But there is hope — in the form of an unlikely group of young heroes gathered together to save tomorrow. Who, or what, is Ultimate X? And in a world where fear and hatred run rampant, how will the X-Men return? Get ready for the war for mutant liberation, with Kitty Pryde as the figurehead for her people, on a collision course with… Jean Grey! Will the planet be torn apart when the mutant nations of Utopia and Tian clash? Or will that fate come at the hands of the world-eating Galactus?! A cataclysm is coming — for the X-Men and the entire Ultimate Universe!
