Apocalypse

In ancient Egypt, the mutant named En Sabah Nur (literally, "The First One") inspired fear and hatred for his inhuman looks and the ability to alter his molecular structure at will. He believes in the "Survival of the Fittest" -- Only the strongest will survive. And for the past 5000 years, he has survived. En Sabah Nur is everything that humans hate and fear about the mutant race; That they aren't just the next step in evolution, but that they will serve as the human race's Apocalypse.
