7. Apocalypse

This immortal mutant is one of the main antagonists in the X-Men comic books, and will be in the center of the next X-Men installment. Born with a mutant X-gene, he turned with blue lips and gray skin, this particularity being the reason his people abandoned him. Baal, a member of the Sandstormers rescues Apocalypse and teaches him about the advanced alien technology.

His power emerges from the mix of this alien advanced technology with his superhuman abilities. He has total control on the molecules of his body therefore he can change his shape and size as desired. There are not many injuries that can be fatal to Apocalypse and his limbs can serve as weapons any time.

Apocalypse has a great ability of adapting his body to diseases and hostile environments; he can project and absorb energy and can deal with whatever technologies he has at hand. All these make him immortal and tremendously dangerous.
