The Mutant Apocalypse (Oscar Isaac) was born at the beginning of human civilization and was worshipped by humans as a god. However, in this way, he was betrayed by the humans he despised the most and was buried in ruins and rocks. Thousands of years passed in the blink of an eye. An accident awakened the apocalypse that had been sleeping for thousands of years from chaos. After returning to the world, he found that the once-noble mutant was now in a very bad situation. In order to create a new world belonging to mutants, he finds the Storm Woman (Alexandra Shipp), the Spirit Butterfly (Olivia Munn), the Angel (Ben Hardy), and Magneto (Michael Fassbender) who wants to live an ordinary life but is still expelled by humans to form the Four Horsemen of the Apocalypse. After sensing the apocalypse, Professor X (James McAvoy) leads the demonic woman (Jennifer Lawrence).
