Killer Croc
- Debut: Detective Comics #524 (March 1983)
- Created By: Gerry Conway, Don Newton, Gene Colan
Killer Croc is unlike most villains that Batman has faced off with. He was originally a wrestler named Waylon Jones. However, he suffered from a rare genetic condition that actually made his skin scale-like, giving him the appearance of a crocodile. This transformation drove him insane, causing him to adopt the “Killer Croc” moniker and turn to a life of crime. Croc was not initially like a crocodile in multiple aspects, and only had the appearance of a reptile-like being. Yet he eventually developed animalistic tendencies, which made him very dangerous to deal with. That also included a nice taste for humans, which is never a good thing for us.
The original version stopped there, but later versions would give Killer Croc not only the appearance of a crocodile but also the same type of teeth and claws reptiles are known for. On top of this, his overall body became enhanced in the strength, speed, stamina, senses, and durability categories. He also somehow developed accelerated healing, which makes him nearly impossible to put down for good. Batman often had to find clever ways to outsmart Croc rather than battle him in a normal fight. Croc does become an anti-hero later, but he has often remained a solid villain and never got along with Batman.
