-- Killer Croc src

Waylon Jones was raised by his Auntie Flowers in Gotham City before becoming the monster he would grow up to be one day. Cursed with an incurable birth defect that made him gradually become more reptilian in appearance, Jones was ridiculed as a child.

As he grew into a young adult, Jones seemed to embrace what he had become. Becoming a professional carnival wrestler, the man adopted the name "Killer Croc". However, tired of people treating him like a monster because he looked different, Croc became bitter with the world and began to turn to violence, such as biting off his wrestling manager's hand when the man verbally abused him. [1]

Croc later took to the sewers of Gotham, finding it an appropriate place for him to live. He was eventually captured by the rising vigilante Batman for crimes he had committed. Killer Croc would make multiple visits to Arkham Asylum but would always find a way to break out.

Red Hood and the Outlaws

At a point when Croc wasn't in Arkham, he fought Roy Harper in Hell's Kitchen but quickly noticed Roy wasn't fighting back. He figured out that Roy was trying to have him commit assisted suicide and comforted the ex-sidekick, knowing Green Arrow screwed him over publicly by taking his shares of Ollie's company, and told him that that was not the way to go out. Roy said he was not that bad of a guy before blacking out, but Killer Croc reminded him next time he would not be so nice.[2] Croc actually became Roy's sponsor for his alcoholism.[3]

Forever Evil

Taking advantage of the Crime Syndicate's arrival onto Earth, Killer Croc took to the sewers of blackened and broken Gotham. Taking in refugees from the chaos above, "King Croc" taught them how to survive in the sewers with him, becoming the leader of a large band of survivors.

Arkham War

Croc and Bane fight during the Arkham War.

As the criminals on the surface began to fight each other for dominance in the unofficially named "Arkham War", Croc struck a deal with the Arkham criminals, lead by the Scarecrow, in order to protect Croc's precious sewer system. As the two spoke in the broken Wayne Industries building, Bane, leader of the Blackgate criminals, arrived and beat Croc in a fight, throwing him out of the window to Croc's apparent death.

However, Croc managed to survive his fall and continued to support Scarecrow's plot for dominance. Being tricked into drinking Venom-laced wine, Croc fell to the drug's effect, becoming an even bigger hulking giant. Even so, Croc again was beaten by Bane in a final fight for control of the city. Left unconscious in the street, Gotham's new protector Bane victoriously stood over him.

Batman Eternal

After the fall of the Crime Syndicate, Killer Croc retook his residence in the sewers of Gotham City. When zombies showed up under Arkham Asylum and began to eat some people down in the sewers, he was initially assumed to be the reason for the victims, but, as Batman and Jason Bard learned, he was simply acting as the champion of the lowest classes who lived down there, people who Batman never directly helped at all and the Gotham City Police Department ignored.[4]

At the behest of Poison Ivy, who herself was teaming up with the Calabrese crime family under Selina Kyle, her friend and the former Catwoman, Croc fought and defeated Bane in single combat, using his knowledge of the workings of Venom that he earned through Arkham War to bleed the Venom out of Bane's body before tying him up for Batman to take into custody. He has subsequently been seen as a regular bodyguard of Selina Kyle herself.[5]

During the Joker's endgame plot against Batman, the clown gassed the entire city with Joker Venom. Croc, meeting up with a group of Batman's rogues that had escaped Arkham Manor [6], decided to help the heroes save Gotham from the Joker. Working together, Croc fended off a crowd of Jokerized citizens while Batman battled the Joker until they both perished beneath the streets of Gotham. [7]

Suicide Squad

At some point, Croc was taken into custody and put onto Amanda Waller's Suicide Squad. [8]

  • Fangs: Killer Croc's teeth are large and sharp yet still human. He can bite down through bone, metal and wood.[9]
  • Superhuman Durability: Bullets fling off Killer Croc's skin and an alligator breaks it's fangs on his scales. He can also survive being thrown from the top of a skyscraper.[9]
  • Superhuman Speed: Killer Croc has an incredible amount of speed for such a large creature. He moves so fast in the sewers that he can come up on prey unnoticed.[9]
  • Superhuman Strength: Killer Croc has an enhanced level of physical strength. He has traded blows with a Venom-enhanced Bane, slammed his way through an armed group of Gotham's SWAT, and carved his way through Gotham's underbelly to create a home within the sewers.[9]

  • Wrestling: Killer Croc's primary fighting style is wrestling. He learned to wrestle in his early adulthood while trying to make enough money to survive in a circus. He combines wrestling with savagery and strategy in order to wear down opponents.[9]
