Villain Overview
Tick! Tock! Feed the Croc!
~ One of Killer Croc's Game Over lines from Batman: Arkham Asylum.

Waylon Jones, also known as Killer Croc, is a villain from the Batman series.


Due to Croc's disease, Jones's skin is scaly and sharp, much like crocodile hide and has reptilian like eyes. Later in his adult life after growing up with his abusive aunt and being an outcast of humanity, Croc exercised nonstop, becoming extremely tall, strong, and dangerous. He also sharpened his toenails, fingernails, and teeth as well as gain a taste for human blood.

Character Bio

His profile in the video game Batman: Arkham Asylum states:

Born with a rare mutation that made his skin green and scaly and grew his body to grotesque proportions, Waylon Jones was raised by an alcoholic aunt and bullied relentlessly for his appearance. He briefly worked as a carnival freak under the name Killer Croc, but his misanthropy grew as did his bestial nature, pushing him to a life of crime. As his physical condition and mental state deteriorate, Killer Croc becomes a more bestial foe, increasingly detached from humanity.

In the original comics, Jones was simply a man with a disfiguring mutation who eventually turned to crime rather than live his whole life as a circus sideshow attraction. Eventually, he came up against Batman, who enlisted the aid of the trapeeze family, The Flying Todds. Sadly, Croc murdered all of them except for son Jason, who joined Batman in bringing Croc down. This directly led to Jason becoming the second Robin, now that Dick Grayson had taken on the identity of Nightwing. Later on, in an effort to differentiate Jason's origin from Grayson's, this story was discarded, and following the Crisis On Infinite Earths, Croc no longer played a role in Jason's origin as Robin.

Later stories, owing to a mix of natural threat escalation for a minor foe as well as confusion about Croc's condition, made him more and more reptilian in mind and body. An encounter with the potions of Poison Ivy during Batman's initial confrontation with Hush left him in an almost kaiju-like state.

In the 1990's Batman Animated Series (Croc's first animated appearance), he was a physically powerful, somewhat cunning opponent, but deep down, he was simply not that bright, and was looked down upon by Gotham's other super-criminals as a result. Once, Batman took advantage of this contempt by disguising himself as Croc in order to infiltrate a gathering of these criminals in order to locate a kidnapped Catwoman. Later on, Croc entered into a bizarre and one-sided romance with Baby Dahl, who felt their separation from other Humans made them an ideal couple. When Croc was shown to be just using her to aid his robberies and living high off them in the company of other women, Batman and Robin had to save both Croc and all of Gotham from the enraged Baby Dahl's vengeance.

Killer Croc in Batman: Arkham Origins

Killer Coc makes an appearance as a minor antagonist in Batman: Arkham Origins (taking place a few years before Arkham Asylum). He's one of the assassins hired by Black Mask to kill Batman.

Croc is first spotted by Batman escorting Black Mask through Blackgate after staging a major prison breakout. Batman then witnesses him, under orders from Black Mask, murder Commisioner Loeb by throwing him into the prison's gas chamber and turning it on. Batman then follows Croc and his employer to the roof where Black Mask escapes and the Dark Knight confronts Croc

Then they fight on the snowy roof of Blackgate Prison.Batman is first caught off guard by Croc's size and strength and his animalistic fighting style.Afetr trying to eat Batman,Croc resorted to throwing giant gas tanks that were being stored on the roof at Batman.

This tactic was his undoing however as Batman used a batarang to explode one of the tanks as Croc was holding it which temporarily incapacitaed him.

Batman then knocked him halfway off the roof before brutally beating him for information on Black Mask, Croc then told Batman of all the assassins hired to kill him on Christmas eve.

As he began to taunt him,Batman knocked him out and left him on the roof of the prison for Liutenant Gordon and his officers.

After causing chaos through the prison,sending Commissoner Loeb to the execution chamber,and getting beaten by the Bat,Croc was placed back in the prison only to be broken out by The Joker later in a prison riot.Croc then finds and confronts Batman before being shot in the back of his bullet-proof head by Gordon who orders him back to his cell.Croc then exclaimed "Screw this!" and left both Batman and Gordon alone. He was presumably locked back in his cell after the Joker's riot, and it can also be assumed that he was the one of many supervillains that were defeated by Batman during the events of Christmas Eve,and was transferred to Arkham after it being reopened by Quincy Sharp.

Killer Croc (Arkham City)

Killer Croc's cameo in Arkham City

Killer Croc makes a very brief (and rather pointless) cameo in Batman Arkham City. After Batman defeats Ra's Al Ghul and gets a blood sample,he decides to leave Ra's hideout and give the blood to Mr. Freeze.While he's getting out of the sewers, Batman decides to throw one of his Remote Batarangs at a certain button.When the button is hit,Killer Croc breaks through the wall.Instead of fighting Batman,Killer Croc says that he smells death on him and that he will die soon and when that happens Croc would feed on his corpse.

Killer Croc made an appearance in Batman Arkham Knight.

He seems to be further mutated being bigger and with big spikes.

The Batman

Main article: Killer Croc (The Batman)

Killer Croc appears in The Batman voiced by Ron Perlman (who also voiced Adventure Time's LichBatman's Clayface, and Teen Titans' Slade). This version of Croc is much more crocodilan than other incarnations of the character (and probably the most intelligent of them all).

"The name is Croc, Killer Croc. But you can call me boss".

Croc makes his debut appearance in the episode,"Swamped" in which,he plans on flooding downtown Gotham by backing up the sewage pipes that are used to transfer water out from the city in order to rob all of Gotham's banks.He is defeated when Batman exploits Killer Croc's weakness for air underwater and half-drowns him, depriving him of oxygen and putting him in an unconscious state.

In "Team Penguin," Killer Croc returns as part of the Penguin's Team Penguin (which also consisted of Firefly, Killer Moth, and Ragdoll ). Killer Croc is defeated when Batman freezes the water he was in. In "Rumors," Killer Croc and his henchmen later appear as one of the captive victims of Rumor after he ambushed him and his henchmen in their hideout. In "The End of the Batman," Killer Croc, Penguin, Ventriloquist, and the Joker team up to commit a crime spree now that they are under the protection of the vigilante Wrath.

His origins are mostly unknown, with Croc providing little evidence about his past beyond his Cajun accent, although one of his henchmen tells Batman that there are different rumors: That he is a genetic experiment gone awry who then turned mercenary, that he deals with the wrong kind of voodoo magic in the swamps, or that he is simply a circus freak (it is never explained which, if any, story is true). 

In the tie-in comic,The Batman Strikes,according to issue 25, he was both a military genetic experiment subject before escaping, then was part of a circus freakshow before escaping that and ultimately coming to Gotham, though it's still unknown if he was born like that as in the comics or if being part an experiment is the reason for his appearance.
