How Killer Croc joined the Tourney
Killer Croc was one of the many inmates of Arkham Asylum at the time of the Joker's takeover. He resided in the sewer system of Arkham where the staff fed him meat and just tried to "forget about him". When Batman was escorting the Joker through the Intensive Care unit, Killer Croc was being escorted by some of the staff (Including Louie Green), with a shock collar around his neck to keep him under control. Croc spotted Batman and claimed that he would hunt him down very soon. He was then taken back to his lair by a number of asylum security personnel when the Joker took control of the Asylum. He saw Batman passing by a locked door adjacent to the sewer. Croc punched the door's window, claiming that he would get Batman soon.

Feed the Croc! (Final Smash)
Based on Raphael's Soul Calibur IV Critical Finish, Croc knocks an opponent back with a hit, and attacks the opponent by biting their neck, reinforcing the idea that he's a crocodile. He says (before he bites them), "Tick tock! Feed the Croc!" He then bites them on the neck, crouching over them while they scream their Star KO scream. After vampirizing his opponent, he gets up, wipes his mouth, and says, "Better luck next time!"
