This started out as one of the 3.5 inch Sonic figures from Jazwares, I used polymer clay cured by boiling to make the boots over the original feet. The shades are polymer clay molded over the wire from a twist tie with a piece of tape painted red for the lenses. The rest of the figure is simply painted with acrylic paint, I used a spray on sealant to prevent it from chipping or getting scratched. The jacket was a challenge, and is cut from black t-shirt material, the sleeves are not actually attached to the shoulders.
As a bonus, I modified the original packaging so I could put the figure inside. I painted "Scourge" over Sonic in a way that would look like graffiti.
