Magneto assembles a group of mutants to fight back against the X-Men and wipe out humans to achieve mutant dominance, as well as teaming up with Maximus The Mad, who wants to destroy humans in the name of his race of the Inhumans. With Maximus around, Professor X realizes that the brotherhood is too powerful for just the X-Men to fight. Luckily, Black Bolt and the Inhuman Royal family come into contact with earth because of Maximus’ threat and Namor arrives onto the surface from Atlantis, so now, the X-Men take to fight for both Mankind and Mutantkind.
