The serum that turned people into Man-Bats was used on Waylon Kirk Jones. But instead of Bat serum, it had Crocidile serum, Snake poison, Lizard flesh, and Venom. Kirk was soon controlled by the serum, giving him headaches, and vomiting. It soon hurt him too much, making him a Man-Lizard. He chose a life of crime then. He didn't like the name Man-Lizard and became Killer Croc.
