The Majority of Batman’s primary rogue’s gallery are mentally deranged killers, or diabolically smart criminal masterminds. But most are generally human. But one stands apart – the freak of nature known as Killer Croc. Born as Waylon Jones, Croc had a rare genetic condition which gave him a crocodilian appearance. Raised by an abusive aunt who mocked his deformity, he eventually ran away and joined the circus, becoming a sideshow carnival attraction, where patrons could come and gawk at the freakish strongman called “Killer Croc.” He eventually departed for Gotham City, where he began a life of crime, one which brought him into conflict with the Dark Knight.
Although he began as just a man with crocodile-like skin, over the years, Killer Croc’s appearance has grown more and more inhuman. He now has a more bestial form, complete with a truly reptilian head, razor sharp claws and teeth, and he even has a tail. His animal nature has made him a formidable foe, but his limited intellect has kept him from ever truly achieving his true potential. Nevertheless, his brute strength and killer instincts have made him an ever present thorn in the side of Batman, who must ever be vigilant that the deadly Croc will once again emerge from the sewers below to wreak havoc on Gotham City.
