Post your favorite goons, mooks and crooks from comics or cartoons.

I've always liked Rhino. He may have been a dumb brute but the opening heist from "Read My Lips" is one of my favorite TAS moments and I've liked that he wasn't just strong enough to take on Batman, but he even had his own theme song separate from Scarface's theme.
