Ultimatum, Volume 4

Ultimatum is a five-issue crossover event that Marvel launched in 2009 in the Ultimate Universe (Earth-1610), written by Jeph Loeb and drawn by David Finch, and tied into several ongoing series including Ultimates, Ultimate X-Men, Ultimate Fantastic Four, and Ultimate Spider-Man. The story begins when Magneto, grieving the deaths of his daughter the Scarlet Witch and his son Quicksilver, unleashes his revenge on all humanity: he seizes Mjolnir, triggers global natural disasters, floods New York under a massive wave, throws multiple cities into chaos, and leaves millions dead. The Ultimates, the X-Men, the Fantastic Four, and Spider-Man are forced to regroup amid the ruins, save lives, and uncover the truth, while another conspiracy lurks behind the chaos. This book is Volume 4 of the series, corresponding to issue #4 of the main run: the Hulk loses control and destroys Doctor Strange's mansion, the released magical forces leave Spider-Man missing, and Doctor Strange dies in a confrontation with Dormammu; meanwhile, Reed, Doctor Doom, and Power Princess cross into another universe to bring back Nick Fury, and Doom publicly admits responsibility for the Scarlet Witch's death; the joint operation of the X-Men and the Ultimates also closes in on Magneto's fortress. The plot is brutal and the casualties are dense, making this a key turning point in the Ultimate Universe's decline.
