"Iron Man, Thor and Hawkeye form the core of the Ultimates-- S. HiI. E.L.D.'s finest fighting force, all too often the only thing keeping the world from total disaster. But when the walls of the mysterious City open up and the hyper-evolved Children of Tomorrow spill out, the Ultimates suddenly find themselves powerless against an unbeatable enemy. As even Thor's Asgardian brethren fall before the Children, the God of Thunder makes a startling discovery about this incredible new threat-- which might not be such a new threat after all"--Page 4 of cover.
