I've made Chaos several times in the past, and this isn't the first time I've used Knuckles' body as the base, but it IS the first time I've used Silver's head instead of Knuckles' or one made from scratch, and I honestly don't know why because the shape is so similar. I wish I could make the whole figure out of translucent material, but thanks to careful application of hot glue I can still do the visible brain nucleus thing. The hands and feet are scratch built from foil and apoxie sculpt.
