The Fiddler
He may be small, he may be ugly but he's got that really cool rockem sockem claw. After surviving fallout from a nuclear chemical spill, the Fiddler found that his left arm was imbued with super-crab strength. No longer was he the funny looking crab always poking around in the dirt at low tide. Now he was a dangerous force to be reckoned with. After learning that Batman enjoyed the occasional crab leg with a crisp Chardonnay, the Fiddler was determined to rid the world of the crazy-crab-eating-crime-figher. Don't be fooled by those beady little eyes flopping around on the front of his head. He keeps a very close eye on Batman's goings on. He'll be ready to strike.
