powers, only driven to devour flesh by their uncontrollable hunger, with the miniseries depicting how they deal with their hunger and how they interact with each other. Like all kind of walking dead, it was decided to establish how the zombified Marvel characters could specifically be killed in the story's context. Kirkman also added some black comedy to the story, and included some gore like most zombie stories do, expressing some shock at how Marvel allowed him and Phillips to incorporate those elements. An early idea Kirkman had for the series involved Luke Cage surviving the zombie plague as the sole human protagonist, given the character's unbreakable skin and that Millar's scripts didn't explicitly identify some characters separately. However, after seeing the finished art for Millar's issues, Kirkman discovered that Greg Land had already drawn Luke Cage as a zombie, so he dropped the idea, which Marvel apparently didn't like anyway. To illustrate the miniseries, Phillips used an art style similar to that he used on Ed Brubaker's Sleeper. As the story was a sequel to the Ultimate Fantastic Four story featuring the zombie infested world, Phillips kept the look of the characters consistent to how Land drew them, with Phillips drawing them with the same costumes Land gave them but with Phillips' own style. He particularly liked to illustrate the zombie versions of Thor and Captain America. Drawing the superheroes as zombies was the most difficult part of the process for him, as he had grown accustomed at drawing characters in street clothes but was forced to draw their muscles in spandex costumes again. Phillips overall enjoyed working with Kirkman in the series, feeling that the most enjoyable part of the process was "playing around" with the huge character cast Kirkman assembled Plot Within the Marvel Multiverse is an alternate Earth designated Earth-2149, which contains alternate zombie versions of Marvel superheroes. The story begins as an unknown superhero from another dimension, brought by the "Hunger", crash lands before infecting the Avengers, X-Men, Fantastic Four and almost all other superheroes. The infection spreads by contact with the blood of the victim, usually through a bite by an infected individual. The zombie superheroes largely retain their intellect, personality and superpowers, and are able to function regardless of the damage to their brain, although they are consistently driven by the "Hunger" for human flesh. The series begins where the Crossover story-arc ended,
