Sephiroth
The ultimate villain of the game, Sephiroth is yet another experiment of Dr. Gast. Injected with Jenova cells and fathered by Hojo, Sephiroth was once a top-ranking member of SOLDIER until he was driven into insanity when he realized his "calling": to become the sole ruler of the Planet. Filled with madness and extraordinary power, he will destroy anyone who gets in his way of world domination.
