Okay, I don't normally post in modelling, but here goes.
Looking good, not a bad model at all. The legs do have a few issues (Goku is trying to hide his cellulite problem methinks).
DarkSlayer, you can't expect EVERYBODY to invent and entirely new style of modelling. Do you expect every book you read to be a completely new genre?
And since I don't think I see an answer, I think the SS does stand for Super Saiyan. The pants are a lighter colour (ie glowing).
