Titel explains it all, I guess. Which Final Boss has the best battle background?
For me, this is an easy one. The best is obviously NeoExDeath.
That background just owns all other ones. I was really impressed when I first saw it. Now I'm hurrying through the Japanese ROM of FF V advance to see if they didn't mess it up. That background just gave you a certain feeling that made you feel a certain something. It was really an incredible battle, the void going in all directions, changing colours, Neo's colour changing, Neo's shaking... Yeah, NeoExDeath definitaly has the best background, IMHO.
Second favorite background of mine is Zeromus' one. Outerspace background is pretty nifty, I would say. Especially when you're actually in the core of the moon with tons of rock around you.
Third becomes hard. Well, I call it a tie bewteen: Cloud of Darkness' one, Kefka's, Chaos' one, Safer Sephiroth's, True Ultimecia's and Necron's... I just can't deside...
So how about you guys?
