You are stupid stupid stupid Neverfate. DO NOT DISS SEPHIROTH !
He is the greatest character (of all time, of everything, games, cartoons, movies, etc) EVER !!!!!
I look up to him, he´s my god.
Sephiroth lost his legs wandering under the earth on the lifestream(earths spirit), and collapsed. The lifestream brought him up to north in an isolated bubble, where he would mentally regain and revive himself, training his mentality to the max, which is pretty high and powerful because of the jenova cells that was inserted in him before birth. Jenova came from outer space thousands of years ago, trying to destroy the hole planet. He eventually mutated parts of his human form, starting out as a monster right arm, he got his one black wing. He manipulated clouds mind into inserting the black materia in the lifestream bubble he washeld in, which holds the greatest, most powerful dark magic in the world. This mutated his lost legs, out from his vains 6 white huge wings appeared. He was then... The One Winged Angel. Strong enough to fulfill his plan, to summon a meteor from the sky to crash into earth, making a scar on the earth, leaking out lifestream, that he would absorb, so he would be strong enough to controll the earth completely, the main earths soul actually. Then he would be the most powerful being ever. He thought he was a Cetra, which was the ancients of earth, those who killed Jenova. The truth is, he became even more powerful than them.
