Wheel Gator from Megaman X2. Out of the bunch I started this guy early and though he'd end up one of the worse looking ones, but he's not bad. I just wish I could make the mouth that an alligator deserves. As one of the defining features for the animal it kinda makes it look bad that it's not there.
