Killer Croc (Waylon Jones) is a supervillain appearing in American comic books published by DC Comics. The character was created by writer Gerry Conway, and artists Don Newton and Gene Colan, and made his first cameo appearance in Detective Comics #523 (February 1983) with a full debut in Detective Comics #524 (March 1983).
Publication history
Killer Croc was introduced during the early 1980s as part of Batman’s expanding rogues gallery. After his initial appearance, the character has been featured in numerous Batman titles, crossover events, and team books such as Suicide Squad, Secret Society of Super‑Villains, and Injustice League. He has also appeared in various limited series, graphic novels, and special issues that explore his origin and criminal activities.
Fictional character biography
Waylon Jones was born with a rare form of atavism that gave him reptilian skin, hardened scales, and other crocodilian traits. His mother died during childbirth, and he was raised by an abusive aunt who frequently berated him for his appearance. After killing his aunt, Jones turned to a life of crime in Gotham City, often operating from the city’s sewer system.
Croc’s early confrontations were with Batman and his early sidekick, Robin (Jason Todd). Over time his physical transformation intensified, giving him a more fully reptilian form, superhuman strength, durability, enhanced senses, and regenerative abilities. He has been portrayed both as a ruthless murderer and, on occasion, as an anti‑heroal figure, particularly when affiliated with government‑sanctioned teams such as the Suicide Squad.
