Here I bring Metal Knuckles he was made with a Knuckles head, body, and shoes and a Metal Sonic's arms and legs, I cut of the tips of Knuckles hair off cause well its Metal Knuckles, the hands of the Metal Sonic arms were broken but that didn't matter since Metal Knuckles doesn't have hands so I sculpted over the arms to make them it into his version of spiked fists, his shoes didn't really need much just those circle things and sculpting over the lego brick thing on his shoes they're glued in place so they can't twist because the hole was to big for the peg to fit properly much like how even though his head and shoulder pads aren't glued or anything they can't really move either, I also sculpted on that little jet thing on his back, and yeah that's about it.
