Industry giant Robert Kirkman (Invincible, The Walking Dead) leaves his mark on the ULTIMATE X-MEN! If one man is capable of disrupting the carefully controlled world of Charles Xavier's School for Gifted Youngsters, it's Ultimate Cable! He comes from a tragic future, and his sinister secrets will shock the X-Men to their very core. He's not the only refugee from tomorrow here today: Bishop is completing his own team of mutants, ready to carry on Charles '''Xavier's legacy. You'll never guess who the new Ultimate X-Men are! But dark times are ahead as the evolutionary emperor known as Apocalypse arrives - and two more monstrous threats, who look eerily like Stryfe and Onslaught, rear their ugly heads! Plus: The X-Men are on a collision course with the Fantastic Four! And the end is nigh as Ultimatum strikes and a tidal wave sweeps through New York City - and Magneto is to blame!
