The Ultimate vs. the Ultimate X-Men: the battle begins. When the X-Men do the worst thing they could to humanity, the government orders Captain America, Iron Man, Thor and the rest of the Ultimate to bring them down.
A small but lethal army, the Ultimate were created to face these and other newly rising threats to mankind.
But the X-Men's founder, Professor X, hasn't been training his students for nothing -- and the young's mutants just might take out the Ultimate's first.
