Killer Croc appears in the 2017 series Batman: White Knight paired up with Baby Doll. The two of them, along with several other Batman villains, are tricked by Jack Napier (who in this reality was a Joker who had been force fed an overdose of pills by Batman, which temporarily cured him of his insanity) into drinking drinks that had been laced with particles from Clayface's body. This was done so that Napier, who was using Mad Hatter's technology to control Clayface, could control them by way of Clayface's ability to control parts of his body that had been separated from him. Croc and the other villains are then used to attack a library, which Napier himself was instrumental in building in one of Gotham's poorer districts. Killer Croc also appears in the sequel storyline Batman: Curse of the White Knight, being among the villains murdered by Azrael.
