10. His Powers Manifested Due To Rejection By A Female
Mutant powers aren't always present when a mutant is born in the Marvel comic book universe and often don't manifest for several years afterwards. Generally, something ends up working as an inadvertent trigger in order for the powers to manifest and it was no different for the first mutant Apocalypse. En Sabah Nur's valiance in standing up to Rama-Tut (Kang the Conqueror), who had decimated ancient Egypt, earned him the attentions of the beautiful Nephri - the sister of Rama-Tut's general Ozymandias. However, after returning her affections, Nephri saw En Sabah Nur's true appearance and rejected him. The resulting rage forced his mutant abilities to come out.
