7. Sephiroth – “Final Fantasy VII”
In “Final Fantasy VII,” as is so often the case, the mixture of a human fetus with extraterrestrial tissue didn’t go exactly according to plan. The experiment created the heroic, white-haired warrior Sephiroth, while also sending him on a path to world domination. It’s hard to say if Sephiroth’s legendary status was a cause or result of FFVII’s global success, but as the mastermind behind one of the most shocking demises in game history, he’s earned it.
