I used a 10 in Sonic with a smaller one driving. The Cockpit was made with a part from a HALO ghost vehicle, some LEGO laptops and other computer things I had lying around. I don't usually work with the Sonic figures because the joints are a bit fragile,(I had a leg break off of this one, luckily I was able to repair it) I saw this 90s style sonic and I new I had to turn it to a Mech. I need to get some pictures of it fighting my other mechs. I hope you guys like it. **edit** I fixed the leg color problem, so here are a couple more pics with the legs being the right color.
It's a masterpiece!
