While messing around with the super form sprites on my DSI (and watching a lot of DragonBall Z), I was looking at them thinking "what could make this more...DragonBall?" So then I thought of what Goku and teen Gohan's hair does when they go super saiyan and was like "DUH". So yeah, now the hair thing that hangs down in front of Nycto's face shoots up when going super.
Also - as a little context as to why the wrist/shoe rings are so black - I've also been thinking about Nycto's creation story and character traits; one of them being that the rings get darker and darker as he uses more and more power. DARK power! :P If he raises his power above what the rings can handle, they will eventually break off, releasing all of Nycto's potential power, similar to what Shadow does (yes, i'm aware that's a Sonic '06 thing, but i liked the concept and that specific CG scene with all the Mephiles')
