8. The Four Horseman of Apocalypse
Fittingly, Apocalypse uses his powers to create for himself Four Horsemen of Apocalypse. These consist of four mutants (or occasionally humans) who he chooses for one of four roles; Famine, Pestilence, War, and Death.
Over the years, Famine has been Ahab, Autumn Rolfson, and Sunfire. Pestilence has been Caliban, Plague, and Polaris. The role of War was taken by Deathbird, Gazer, Hulk, and Abraham Kierosm while Death has been Archangel, Caliban, Gambit, and Wolverine.
However, when these heroes are turned into any one of the Horsemen, they become twisted versions of themselves. Regardless of whether Bryan Singer uses the characters listed above or some of the other mutants in the live-action franchise, it would be a massive shame for this part of the character’s mythos to be excluded from his big screen debut.
