It's Super Sonic! Based on the Sonic Hedgehog Blend (https://www.blendswap.com/blends/view/90639), I made the new textures for the body and the Chaos Emeralds (except for the eyes, that i found online) The CE's i made out of the original diamond blend (https://www.blendswap.com/blends/view/78349).
I do not claim any of this as my own (other than the glowing textures). and credit is given to all the original blend authors.
now there are a few updates concerning the materials. i've finally figured out how to bump map the emission (or the glossy of it) so it looks more like the Unleashed cutscene. i've also updated the transitioning factor of it to make it easier to animate (use the Fac value at the top of the material settings in Properties)
