The blockbuster conclusion of superstar writer Mark Millar's run! The Ultimates 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 Ultimates to bring them down. A small but lethal army, the Ultimates assembled to face these and other newly risen threats to mankind. But the X-Men's founder, Professor Charles Xavier, hasn't been training his students for nothing - and the young mutants just might take out the Ultimates first! Next, with the X-Men still licking their wounds from the battle, can Professor X's mutant team survive the return of their most powerful foe? Witness the return of Magneto!
