Killer Croc is an enemy of Batman with incredible super-strength and a crocodile-like appearance. This mutation was originally a birth defect, although he becomes more reptilian over time due to genetic experimentation. Despite his brutal savagery and heightened reflexes, his animalistic mentality results in lower intelligence. He has been a member of the Secret Society of Super-Villains and the Suicide Squad and spends most of his time imprisoned in Arkham Asylum. Killer Croc was created by Gerry Conway and Gene Colan, first appearing in Detective Comics #523. (1983) ||
