Since ancient times the world’s first mutant, Apocalypse, has been worshiped as a god. Apocalypse has supposedly influenced all the world’s major religions, he is believed to be Ra, Krishna, etc. and Zeus. After sleeping for several millennium, Apocalypse is awakened and disgusted by the sight of the modern world and the current state of the mutants. So, he decides to recruit his four horsemen (elite mutants) to aid him in his world “cleansing,” of all non-mutants.
Apocalypse was the first person to express the mutant X-Gene and thought to be the possible originator of the gene itself. His powers include but are not limited to: Total control of every molecule in his body, changing his form, changing size, transform his limbs into weapons, regeneration, enhance himself physically, adapt to survive any environment or disease, any physical super power, telekinesis, telepathy, technopathy (direct interface with various technologies).
