Cataclysm is a sequel to the Age of Ultron crossover, set in the mainstream Marvel Universe. At the end of that story, Galactus is displaced to the Ultimate Marvel universe. Unlike the Ultimate Galactus Trilogy, this is the character from the mainstream universe, and not a reimagination. The story was published in two parts, "Hunger", set in space, and "The Ultimates' Last Stand", set in Earth. The second part has tie-ins with the three ongoing Ultimate Marvel comics at the time,, and. The "Survive!" one-shot narrates the aftermath of the event. After the event, the Ultimates and X-Men comics were closed. They were replaced by the "All-New Ultimates" and "Ultimate FF". The Spider-Man comic was renamed as "Miles Morales: Ultimate Spider-Man". The "Hunger" miniseries was made by Leonard Kirk and Joshua Hale Fialkov, who had been working with Ultimates. Fialkov commented that he was a big fan of Galactus and his creator, Jack Kirby. He pointed that the Ultimate Marvel imprint had always tried to keep the superhero fantasy as grounded as possible, and that he intended to use Galactus to place the characters into a complete unexpected crisis. "What I hope comes across is the sense of wonder that’s being brought into the Ultimate Universe... with the smart, modern tone Brian has established." "Hunger explored the cosmic characters of the Ultimate Universe, in particular Rick Jones. "Brian created a unique and interesting take on Rick Jones that’s really smart and fun. He’s like Spider-Man taken to the extreme... with great power comes great responsibility, but he just wants to have fun and be normal." He also commented that he had been checking all the recent events at the Ultimate imprint, trying to write a cosmic story that would be unique to it and that could not take place at the mainstream universe. As the story was set in the space, "Hunger" had no tie-in comics. There were rumors at the time that Marvel would close the Ultimate imprint, which were fueled by the name of the publication and the reunion of Brian Michael Bendis and Mark Bagley for the main comic. Bendis and Bagley had started the imprint in 2000 with Ultimate Spider-Man. When asked about those rumors, editor Mark Paniccia simply replied "Let me say this, there are some stunning resolutions coming across all the titles!" Bendis dismissed it as "unsubstantiated rumors" at his Tumblr account.
Plot
is displaced into the Ultimate Marvel universe. When he crosses the portal, the Gah Lak Tus swarm senses his energies, and submits to him. He decimates the Kree and the Chitauri alien races, and he is opposed by Captain Mar-Vell, Rick Jones and Silver Surfer. Mar-Vell dies, attacked by the swarm, but Rick Jones takes his suit and activates a bomb that destroys it. Rick Jones and the remains of the swarm fall into another dimension, and Galactus heads to planet earth, killing Vision in the process. Sensing the reality Galactus hails from, Vision manages to send a cryptic message to Earth, pleading for the Ultimates to ally with Reed Richards before she shuts down. Galactus turns out to be more powerful than the Ultimates and the conventional military; realising the desperation of their situation, the Ultimates ally with the inexperienced Miles Morales, the traitorous Reed Richards and the outcast X-Men. Tony Stark discovers that he comes from an alternate reality, so Richards and Morales are sent to it to find information. Arriving on Earth 616, they sneak into the Baxter Building and retrieve information about Galactus, who that reality's Richards had defeated before. The two are discovered by Valeria Richards, who recognizes Richards as not her real father, but manage to escape. The Ultimates' plan is set into motion: Kitty Pryde receives the Giant-man serum, so that she can destroy Galactus' machine and attack him while in giant size. They also employ Jean Grey to telepathically read Galactus' strategy, but when he senses them and attacks, Steve Rogers sacrifices himself to buy the Ultimates more time to execute their attack. While Galactus manages to seriously harm Pryde in spite of her intangibility, her sacrifice is ultimately a distraction: Richards opens a portal to the Negative Zone, intending to swallow Galactus into it where he will starve with no energy to feed on. Galactus resists the portal's pull, which threatens to tear apart reality if open too long, so Thor sacrifices himself to push Galactus inside; a reluctant Stark and Richards close the portal with Thor still inside.
