Teen Titans Go! Wiki

Waylon Jones, also known as Killer Croc, is a reptile-like enemy of Batman. Although he is usually fighting the Caped Crusader in Gotham City, Croc's made a few cameos in Teen Titans Go! as well.


Unlike villains who get mutated later in life, Waylon was born with his genetic mutation, a trait that caused his inactive reptile genes to become active. Obviously, this attracted a lot of unwanted attention; people ridiculed young Waylon's appearance, and it took a negative toll on him.[1]

As time moved on, the mutant went from hating who he was to embrace it. He joined the circus as an alligator wrestler and called himself "Killer Croc". Even in a place as crazy and accepting as the circus, Croc was still treated like an animal. Finally, he found a home in the sewers of Gotham City, where he engaged in numerous criminal activities. Unfortunately for Killer Croc, Batman eventually caught up with him, and he was imprisoned in the Belle Reeve facility. It was there that Croc took up a contract with the Suicide Squad.[2]

Teen Titans Go! features Killer Croc first in the episode "Nose Mouth", where he makes a brief appearance alongside Kyd Wykkyd, Control Freak and Plasmus in Robin's dream. He has also appeared a few other times throughout the series, but nothing more than cameos.


Newer version of Killer Croc.

In his first few episodes, Killer Croc is completely covered in cyan scales. Both his hands and feet end in spiny claws, and his mouth is lined with a sharp set of teeth. Croc's brow is very defined, and his upper body is in exceptional shape. As for clothing, he wears a tattered pair of blue-gray jeans.

"The Inner Beauty of a Cactus", Killer Croc's third episode appearance, saw him get a slight redesign. He is now more green than cyan, and his scales are also much more defined. In addition, bony protrusions stick out from the top of his skull all the way down his spine. He also has a couple of spines on the side of his face.

Physical Appearance

Killer Croc is a mutated humanoid with green scaly skin and sharp yellow teeth.

    • Superhuman Durability: The scales covering Killer Croc's body have been known to withstand bullets and other damage.
    • Superhuman Strength: While not on the level of Superman, Killer Croc is stronger than any normal human, even if they are in peak physical shape.
    • Superhuman Speed: Thanks to his crocodile ancestors, Killer Croc has outstanding speed, especially while in water.


  • Bilingual: Although not the smartest of Batman's adversaries, Croc is proficient in English and French.[4]
