Silver Sonic Mk 3, as he appeared in issue 225 of the Sonic the Hedgehog comic. Silver Sonic was made from a 5 inch Sonic the Hedgehog, I cut off his regular spines and sculpted the new sword-like spines in their place. The fingers are made of the Sonic and Shadow Back spines I cut off to make customs in the past, and he has toy car wheels in his feet (he can't exactly roll, but they do still turn, and that's pretty nice.) All of the sculpting is done in polymer clay. I decided to make a larger than usual figure to celebrate Sonic's 20th anniversary tomorrow.
