Sephiroth. Genetically enhanced before he was born. Joined SOLDIER and became even weirder. Died by falling into the lifestream, and still managed to come back, and haunt Cloud until he was killed while Cloud himself was in the lifestream. Totally psycho too!

[ooc: Seriously XD [what?! srsly?! o.o go play FF7, 8, and possibly 12...possibly]]
