"Tick Tock! Feed the Croc!"
―Killer Croc, during one of the game over screens[src]

Waylon Jones, also known as Killer Croc, was abandoned and put under the guardianship of his incredibly abusive and alcoholic aunt after his mother died giving birth to him and his father abandoned him, due to his appearance, the result of a combination of body mutation, genetic disorder and rare skin disease he was born with, that only worsened over time. Brutally abused in his home and locked up in a closet like an animal as his aunt drank and engaged in sexual activities and relentlessly bullied at school his entire life, Waylon accepted his place in society as always being seen as a monster.

After his time of being abused and bullied went too far, Jones then embraced his animal instincts and violently murders and devours his aunt after finally reaching his breaking point. Waylon fled from society and eventually went joining a traveling circus, where he was made part of the freak-show, becoming and adopting the stage name known as, "Killer Croc". Bonding with his fellow carnival performers and workers in the show, Jones finally felt as if like he had a family for the first time.

Until this came to a tragic end however, when vicious audience members in Gotham City made a horrendous attack, destroying the circus/carnival and killing all whom Jones felt affection for. Seeking revenge on all humanity for their crimes and viewing them as a disgusting, selfish and judgmental waste sacks of flesh, Croc became a cannibal murderer, began to devour countless individuals to survive, becoming a monster in body and spirit. Driven by hatred and a lust for blood, Croc regularly works with Gotham's various mob organizations as a brutal and cannibalistic hit-man to satisfy his appetite for violence and money.

Jones took orders from anyone who could provide him with money and a larger scope of victims, often employing himself to the mob for money, before being apprehended by Batman. As the years went on, Jones's condition would make him more and more into a monster, eradicating any traces of humanity that might have been left as Croc became a monster in body and spirit. Always seeking his next meal, Croc has never forgotten the scent of Batman and lusts to kill and devour the hero in retribution for his capture at his hands.

He was 28 years old, 10'5, and weighed 485 pounds by the time of Batman's second year at crimefighting. He was also one of the eight assassins hired by Black Mask (actually the Joker in disguise) to kill Batman on Christmas Eve.


Born with a rare mutation that made his skin green and scaly, and which 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.

Killer Croc grew up with a severe medical condition of an unknown form of epldermyoletic hyperkeratosis, although this was conflicted with reports suggesting he had regressive atavism. Regardless, he eventually had various warrants, including 7 counts of assault, 7 counts of aggravated assault, 6 counts of murder of the first degree, 14 counts of murder of the second degree, 12 counts of manslaughter, 4 counts of drug dealing, and 1 count of reposterising.

He was 28 years old, 10'5, and weighed 485 pounds by the time of Batman's second year at crimefighting. He was also one of the eight assassins hired by Black Mask (actually the Joker in disguise) to kill Batman on Christmas Eve.

Batman: Arkham OriginsEdit

The first of the eight assassins hired by Black Mask (secretly The Joker in disguise), Killer Croc assisted his employer in breaking into Blackgate Prison in order to free Julian Day, alias "The Calendar Man", and execute Commissioner Gillian Loeb. After Black Mask discovered that they were being tailed by an aerial drone, Killer Croc was ordered to destroy it and retrieve the memory card. However, Killer Croc instead smashed the drone to the ground, and despite assuring Black Mask that it was destroyed, the memory card survived.

As Black Mask escaped by helicopter, Croc stayed behind to take on Batman, who was in pursuit of Sionis. While Jones possessed far greater strength and a crushing jaw, Batman's quick wit and gadgets allowed him to overcome Killer Croc, eventually defeated, and dangling him over the edge of a cliff for an interrogation. Croc revealed that Mask had hired seven other assassins and mercenaries that would soon come after him and take him down that night, but before Batman could extrapolate further data, Captain Gordon arrived, forcing Batman to retreat and leave Croc to be taken in by the GCPD. Killer Croc was also responsible for Howard Branden and his SWAT Team's later antagonism of Batman, due to Killer Croc, after undergoing interrogation at the GCPD lockup, revealing that he and seven other assassins were hired by Black Mask with a reward of $50,000,000 to kill Batman, which piqued their interest in the reward.

He was then taken into custody by the Gotham police. Croc was seen briefly at Blackgate Prison attacking Batman during the Joker's riot, luckily James Gordon, interfering with a sniper's aim in anger for the sniper earlier wounding Warden Martin Joseph, caused a stray sniper round to graze Croc in the arm, forcing the mutant criminal to flee elsewhere in the prison in irritation, also telling Batman that he can have the Joker for all he cares.

Batman: Arkham AsylumEdit

"I've got your scent, Batman...I WILL HUNT YOU DOWN."
―Killer Croc to Batman upon the latter's arrival to Intensive Treatment[src]

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.

Ark mans standard GameOn 122

Batman and the Joker bypass Croc on the way to the Intensive Treatment Center.

Eventually, Batman was forced to enter Croc's lair in order to retrieve the antidote to the 'Titan' drug, which the Joker was experimenting with on some of the patients. Batman soon learned of the antidote's location after a discussion with Poison Ivy. He then followed another villain, the Scarecrow, down into the sewers who threatened to dump his fear gas into the water supply, which would lead straight to the Gotham River. Before he could do so, however (unaware to Scarecrow that the Arkham sewers was Killer Croc's new cell), Croc jumped out of the water and grabbed Scarecrow. Batman attempted to subdue Croc by activating his shock collar with a batarang. Croc flinched for a moment before jumping back into the water, dragging Scarecrow down with him. Batman made his way to Croc's lair, where Croc attacked him several times, only to be repeatedly foiled by Batman activating his shock collar with batarangs. Eventually, Croc cornered Batman at the entrance of the lair and charged at him. Unbeknownst to him, Batman had laced the floor with explosive gel and detonated it as Croc ran across it. Croc then plummeted into the water below, vowing revenge on Batman.

In one of the three alternate endings after the credits, Killer Croc emerges from the water by Arkham's docks and grabs onto a floating case of Titan.

Batman: Arkham CityEdit

"Your scent is...Different. I smell death on you..."
―Killer Croc to Batman after the latter defeats Ra's al Ghul[src]

Croc remained in the Asylum sewers even after the events that transpired as a result of Joker's plans (implying that that the alternate ending depicting Croc was not canon). After Arkham City was completed and almost open for business, Hugo Strange sent TYGER Operatives to lure Croc out of the sewer system using human body parts as bait, which initially failed, but they were still able to capture Croc after the beast emerged from the sewers once the supply of bodies ran out. He was soon sent to Arkham City, where he roamed the sewers and subway system, murdering and feasting on anyone unfortunate enough to stumble upon him or his hideout. A hidden room can be found, which contains a dirty, broken down mattress, human skulls, and his collar, suggesting that Croc stayed there initially before roaming around the sewers freely.

Mister Hammer led a small group of Joker's men beneath the sewers to control access to the subways, and formed an alliance with Croc, as they both came from a similar past. Croc promised Hammer to only feed on the Penguin and Two-Face's men and to spare Joker's.


Croc beneath Arkham City.

Though Croc is not featured as a main character or adversary throughout the game, he makes a cameo appearance, though only at a specific point in the game's main storyline. After fighting Ra's al Ghul, Batman can throw a Remote Batarang at a switch behind a gate that leads to a sewer exit near the Sionis Steel Mill, at which point Croc will burst out of the wall behind it and attempt to attack Batman. Batman then states that he doesn't want to fight him and just wants to move through.

Croc says that Batman's scent has changed and senses death on him (from the Titan poisoning Joker inflicted on him earlier), remarking that there is no need for a fight as he will feed on Batman's corpse once he dies.

Catwoman mentions Croc as an option to open Hugo Strange's vault. Catwoman and several other inmates then claim that Croc ate Scarecrow during the events of Arkham Asylum.

During the events of Protocol 10, Croc fed on the bodies of any inmates who were killed during Strange's plan and washed up beneath the sewers.

After Arkham City Edit

While most of the Arkham City inmates were successfully arrested and transferred back to the reopened and refurbished Blackgate Penitentiary after Arkham City's shutdown, Croc was able to escape from the sewers underneath Arkham City and into the swampy outskirts of Gotham. Around this time, he made a temporary hideout within an abandoned lighthouse off the coast of the ACE Chemicals factory. Situating himself there, Croc continued in his cannibalistic tendencies by capturing random victims, imprisoning them, and devouring them. He was eventually captured, tranquilized, and placed within a secured cargo of an airship by a specialized team hunting Croc and placed aboard the prison blimp Iron Heights Penitentiary on October 27.

For the next few days, he was experimented upon by its sadistic warden, Ranken, including having one of his forearms forcibly amputated via a buzzsaw. Impressed by his regeneration capability, he then experimented on the other prisoners in an attempt to weaponize it. However, this came at a cost: The repeated torture he was inflicted with caused an adaptive reaction to the trauma to activate that severely mutated the already long-deformed serial killer into something more bestial in appearance. To make matters worse, the sedatives were growing to have even less of an effect on him than before, causing the warden to consider terminating him if the time came.

True to the test results, Croc was able to wake up from the tranquilizers long before he was ever intended to, likely as a side effect of his continuously advancing mutation, murdered his captors, and caused the airship to crash near Bleak Island by sabotaging the engines. By the events of Batman: Arkham Knight, his earlier victims were only piles of decomposing bones left behind in the lighthouse.

Croc's mutated form also appears within a fear toxin induced hallucination, now sporting a much larger appearance with spikes and a fully grown tail, before being run over and killed with the batmobile, under Joker's control within the nightmare.

Season of Infamy: Beneath the Surface Edit

The crash was ultimately witnessed by Nightwing, who promptly notified Batman, with both headed to the ship to investigate. Batman gradually learned that the ship contained Killer Croc and attempted to apprehend him, also witnessing him abduct the warden. However, he quickly realized that Killer Croc had an ulterior motive regarding the warden since he just abducted him rather than eat him as he usually does to his victims. They eventually discover the reason for Croc's hatred for the prison warden, with Batman and Nightwing arresting the warden after working together to subdue Croc.

Challenge MapsEdit

After the events of Arkham City, Killer Croc made his way to the Iceberg Lounge and watched Batman fight many of The Penguin's men.

Personality Edit

The basis of Killer Croc's very existence is a fundamental and insatiable hatred of humanity. This allowed him to murder, mutilate and cannibalise dozens of people for no other reason than sheer misanthropic hate and lust for blood. Having gradually shedded human morality or whatever humanity he may have retained due to his traumatic upbringing, Croc accepted his place in society as a monster due to being treated like one his entire life because of his skin condition and became an animal of body, mind and spirit eventually over the amounted years of abuse. His views on humanity are that they are now meat and bags of flesh which also makes him capable of murdering them in droves utterly without remorse.

Even so, Croc is capable of thought process despite his barbaric mind but commonly at the mercy of his animalistic and psychopathic mental state. At the beginning of his criminal career, Croc was an assassin and he showed an equal level of interest in money or fame but his main was goal was prioritised as the highest body count imaginable. He has displayed a dark sense of humour at times such as claiming in his therapy sessions that after biting off Aaron Cash's hand, that he "almost choked on [Cash's] bony hand'. Unfortunately, Croc's moments of intelligence are few and he is commonly known to roar in response to his more human side, allowing the animal side to take control fully again. His savage impulses and instincts also cause him to be highly impulsive as he could not predict the trap laid out for him by Batman in his lair but instead ran at full momentum towards the Dark Knight, falling into the explosive gel and his defeat.

Psychological profile (by Dr. Penelope Young)Edit

180px-Killer Croc img

Croc's photo

Psychological Profile: Jones was born with a rare mutation that created a series of physical disfigurements which have worsened intensely with age. His skin is green and scaly and his body has grown to grotesque proportions. While these disfigurements are unquestionably the sources of Jones' various psychological disorders, his intense misanthropy seems to also derive from an understandably difficult childhood which included alcoholic relatives and social rejection by his peers. He increasingly embraces an animalist, subhuman conception of self.

Additional notes

"His acute misanthropy makes him difficult to treat, he refuses to respond to socialization, reacting only when he is acknowledged as a dangerous beast, which is clearly how he views himself. It may be that his physical disfigurements are so severe, he will never be able to truly integrate into human society. This challenge is made clear by repeated (and occasionally successful) attempts to maim and kill the asylum's orderlies and doctors."

Killer Croc's Game Over lines.

  • "I will enjoy feasting on your bones."
  • "Tick Tock. Feed the Croc."


  • After defeating Croc, Batman would later tell Alfred that the source of his information was a "human-shaped crocodile", to Alfred's mild amusement and surprise.
  • The Arkham Origins version of Killer Croc is significantly smaller than his Arkham Asylum portrayal (7 inches and 95 lbs smaller, to be exact), most likely because his mutation is less developed.
  • Out of the Eight Assassins, Killer Croc is the only assassin to act as a personal henchmen for The Joker (under the guise of Black Mask) in addition to being assigned to collect the bounty on Batman.
  • If the player makes Batman move about after Killer Croc comes out of the elevator to spot him, Killer Croc's head will follow him no matter where Batman moves about.
  • In the beginning of the game, Joker can be heard saying, "Tick-tock, tick-tock, is that a crocodile I hear?" This is a nod to Peter Pan, which features a crocodile that at one point swallowed Captain Hook's alarm clock, causing people around it to hear the infamous ticking as it drew near. As another comparison, Peter at one point cut off Hook's hand and fed it to the crocodile. The crocodile, having loved the taste, has now followed Hook wherever he goes in order to eat the rest of him. This is very similar to how Killer Croc devoured Cash's hand and has now developed an intense hatred of him.
  • In Arkham's Medical Facility's Sanatorium, an old prison cell is used as a Riddler Challenge puzzle to unlock Croc's Biography. It is presumed that this was his old cell or perhaps where he was kept when they studied him.
  • Croc is notably thinner in Arkham City, likely due to an inconsistent food supply.
  • Killer Croc cameos in Injustice: Gods Among Us in one of the stage transitions in Arkham Asylum. When the player attacks their opponent near the edge of the Mess Hall arena, they will be knocked into a room where Killer Croc, the Penguin, Two-Face, and the Riddler all attack the fighter before they move on to the Cell Block arena.
