Killer Croc

"You're just in time... cuz the bird wasn't enough. And now I'm hungry for bat." - Killer Croc

Killer Croc, aka Waylon Jones was born with a genetic mutation that gave him many reptilian features. As he got older, these genetic anomalies increased. He started as a wrestler who also wrestled crocodiles as his gimmick (hence his name) but eventually got into thuggery. Due to genetic manipulation, he's since become far stronger and more resilient, but also more animalistic and far less intelligent. He's an enemy of Batman] and hates a good deal of humanity in general.
