A half-man, half-reptile, Killer Croc wants to submerge all of Gotham in water in order to facilitate his plundering of the city. This version of the character is also one of his more intelligent incarnations as he is capable of thinking rather clever ideas in order to obtain money. Compared to other incarnations of Killer Croc, this incarnation actually takes the appearance of a humanoid crocodile, fitting better with his alias.
Although his origins are never explored in the series, in the comics, The Batman Strikes!, it is revealed that he was once a mercenary who volunteered on an experiment of DNA splicing and ends up becoming a half-crocodile/alligator and escaped due to having fear of being locked up in a cage, he takes refuge in a circus but ends up lcoked up as well and escaped the same, and decided to become a criminal for survival.
After flooding downtown Gotham by backing up the sewage pipes that are used to transfer water out from the city. so it's banks were easy to pillage, Croc was eventually taken down by The Batman. Though the battle was lengthy, The Batman exploited Killer Croc's weakness for air underwater and half-drowned him, depriving him of oxygen and putting him in an unconscious state. Thus, he was stopped just in time by Batman.
Another time, Killer Croc joins up with Team Penguin alongside Firefly, Ragdoll, and Killer Moth, a group of Gotham villains formed by the Penguin, and his job is to sneak into waterside facilities underwater and take out the guards. When the team ends in failure, he is defeated by Batman.
Croc was also seen among the many villains that was captured by the vigilante Rumor. When Rumor intrude to his hideout and defeated his crew, Killer Croc thought it was Batman, but when he smells, he is proven wrong. Once freed he tries to kill Rumor but is stoped by Batman and Robin and is later arrested with the other villains.
He was last seen as one of the villains alongside Joker, Penguin and Scarface being assisted by the Wrath and his sidekick, Scorn. The four of them steal money off a boat while Wrath and Scorn fight Batman and Robin. He escaped from the police when they arrived to the scene by diving into the sea. Batman's identity is then promised to the villains by Wrath to make it up to them almost getting caught. This never happens due to Joker gassing them before they could tell him Batman's identity.
