This was done as a joke, Sephy. I don't really think Nanaki is Vader, it just looks funny.

To be perfectly honest, I don't find any aspect of VII, or any of my other comparisons other than XII, to be like SW. Sephiroth as Vader is a huge stretch. They both wear black, they're both feared warriors, they both went rogue, that's about it. I could find some wild ones if I cared enough to look deeper, but it's just for fun.

And yes, I did know the Anakin-Nanaki trick. I did point it out after all.
