Elements of "Ultimatum"'s story were established in the Ultimates 3, Ultimate Power, and Ultimate Origins miniseries, all of which featured a banner reading "March on Ultimatum" on their covers. During "Ultimatum", the three Ultimate Marvel titles (Ultimate X-Men, Ultimate Spider-Man, and Ultimate Fantastic Four), featured tie-in stories about various characters and events that occur throughout "Ultimatum". The series mainly builds on the events of Ultimates 3, in which the villainous robot Ultron shoots and kills the Scarlet Witch. Ultron's rebellion and Wanda's death lead to a series of events which end with the apparent death of Wanda's brother, Quicksilver, who is shot by Hawkeye when Quicksilver uses his super-speed to intercept the bullet meant for his father. Magneto vows revenge on the Ultimates. Before escaping the Ultimates, Magneto is able to steal Thor's hammer which he uses, along with his magnetic abilities, to reverse the Earth's polarity. It is further revealed that Doctor Doom was manipulating these events. Comics are in great condition. Mike comic
