X-Men ‘97season 2 focuses on Apocalypse, the world’s first Mutant who uses his incredible power and immortality to cause trouble across the Marvel timeline. Beyond his personal strength and access to Celestial technology, one of the things that makes Apocalypse such a terrifying foe are his allies. No matter what era he’s operating in, Apocalypse likes to round up a quartet of powerful mutants and turn them into Horsemen, which typically involves a mix of brainwashing and enhancing their powers through physical modifications.
