I got such a positive response from my Rouge Transformer a while back I decided to continue the series with Sonic. With Rouge the toy's robot mode just happened to fit, but with Sonic I picked the base toy specifically for its car mode, a F1 race car, and leadfoot also happened to be the perfect height to match Rouge so it all worked out. The body is pretty much a repaint in Sonic's colors, though the way the hands fold up make the colors in car mold hold together VERY well, he looks almost patriotic with the red, white, and blue sections. Like with Rouge the Sonic character head is made out of a Marvel Heroics ball with sculpted on spines and face, it clips on over the gestalt mode head.
