Fan Casting Killer Croc in The Dark Knight

Killer Croc, also known as Waylon Jones, is a high profile criminal and one of Batman's most challenging adversaries. Croc is best known for his reptilian appearance which is due to his medical condition. In his early appearances, this manifested as tough, crocodile-like skin, but over the years he has slowly taken on more crocodilian features, essentially becoming an anthropomorphic reptile.
