"I live underground. Y'all are just tourists!"

- - Killer Croc to General Thunderbolt Ross

Waylon Jones is a former crocodile wrestler from Florida turned criminal under the ring name of Killer Croc.

Years later, he would be released and made a member of the Suicide Squad.

Fighting the Batman
"I caught your scent..."

- - Killer Croc to Batman

Killer Croc would meet Batman for the first time when the vigilante attempted to confront the Penguin and his Children of Arkham henchman at the Skyline Club during their raid of the establishment. While the Penguin argued with the Dark Knight, Jones just prepared for his command to attack him. The Penguin eventually left to find Catwoman, leaving Killer Croc and Batman fighting in a violent duel. Batman took a beating, and was almost killed by the lizard-like Metahuman before escaping.

Attack on the Mayoral Debate
Killer Croc would later appear once more with the Children of Arkham during their raid at the debate between Harvey Dent and Hamilton Hill. While hidden in the shadows, Jones took out Vicki Vale in order to "host" the debate, and killed two GCPD officers who tried to take him down.

While he defended the doorway from incoming GCPD officers, Killer Croc realized he got distraught while Batman was fighting against the Penguin, quickly shifting his attention back to the Knight of Gotham. Rushing towards Batman, Croc easily overpowered him, even damaging his armor's chestplate, but was taken down when Batman used a Sonic Batarang, immobilizing the Metahuman. He and the Children of Arkham members were then arrested by the GCPD and transferred to Arkham Asylum.
