The series begins where the "Crossover" story-arc ended, with Magneto destroying the cross-dimensional transporter after the Ultimate Fantastic Four and survivors escaped back to the Ultimate universe. After a battle with the zombies, Magneto learns that the Acolytes and Forge are still alive on Asteroid M. However, before he can reach them, he is attacked once again, killed and eaten by the zombies, though he manages to behead the zombified Hawkeye. The Silver Surfer arrives on Earth and informs the zombies that his master Galactus is en route to devour the planet. The zombies attack the Silver Surfer, who is overpowered and devoured by several of the former superheroes: Colonel America, Iron Man, Giant-Man, Spider-Man, Luke Cage, the Hulk, and Wolverine. After acquiring a portion of the Power Cosmic, they slaughter most of the remaining zombies, intent on satiating their hunger despite the latters' unpalatability.
