I've already filled in the entire roster of playable characters from Sonic the Fighters with Nack, Bark, Bean, and Honey (who I even made quite recently) but I was surprised when someone asked me to make Rocket Metal, from the game's opening cut scene, who even now is only playable by hack. Of course the base toy was a 3 inch Metal Sonic, with features like the rocket nozzles, clamp hands, and head mods all made out of apoxie sculpt. Heh, it looks like you could just scale this guy's head up into a funny Metal Sonic themed space pod right?
