It's mutant against mutant-brother against brother-as Cyclops and his X-Men risk their lives to take down the young man known as Havok, who has unwittingly become a pawn in Magneto's deadly game. Plus, an unexpected appearance by another hero from the Ultimate Universe turns the dangerous situation from bad to worse. Part 3 (of 5)
