Guyver as in the anime/manga "Bio-Booster Armor Guyver(It's a list of links to Guyver sites; you have to scroll down past the ads, though!)? Well, I sort of did an Ultraman, and the designers admitted he was the basis for the look of this character, only they wanted something more organic and stylized. But it was P4, and used some P4 morphs, and would have to be re-created. And it didn't have the "head fin." This would require a lot of modelling, or a VERY detailed texture and Bump map to pull off - and some parts of the character would probably need transparancies to work right.
