Well Sephiroth was originally going to be female and their is a theory that he was in his first form anyway.Nile McMorrow said:Maybe that purple haired dude is a male doppelganger of lighting? I also noticed the feathers and what appears to either be a cloak of feathers or a wing. Anyone guessing something like Septhiroth (I know its unrelated but it could be a similar sort of thing, no?)?
1. You never see child Sephiroth, never even teenage Sephiroth.
2. In a cut scene from the final product of FFVII a female body is found and its believed to be Sephiroth.
