Waylon Jones (Earth-1)

Waylon Jones is a mutated monster, and enemy of Batman, known as Killer Croc.

Reptilian Villain
Following his transformation into the beast known as Killer Croc, Waylon Jones began feuding with Gotham City's protector, Batman.

Batman VS Killer Croc
Batman and Robin found Killer Croc at Ace Chemicals, following a series of criminal events caused by him. Croc fled across the city, and into the sewers, where the duo caught up to continue the fight. Once there, Batman and Robin came across Croc's base of operations, and discovered that he had been using Venom, the same steroid that gave Bane his immense strength. However, this did not help Croc, as Batman and Robin managed to defeat him in battle, and leave him to be arrested.

Breaking Out Of Arkham
Croc was broken out of his cell in Arkham Asylum by the joint effort of Harley Quinn, Mister Freeze and Firefly. He would then go on to help them lead a mass breakout of the prison, with help from other fellow villains of Batman.
