Originally surnamed Etchinson Arnolds uncle who was a politician disowned him and his father after realising his own brother was a thief and a murderer and had his surname forcibly changed to Etkar to avoid any public association with him. As it turned out Arnold would prove to be just as bad as his father if not worse as he was commited to an aslyum after butchering nineteen people. Years later Arnold managed to escape from Arkham with help from a unknown source, he focussed his attention on his brothers son (Henry Etchinson) who was also an up and coming politician running for mayor. He turned up when Henry was at an election rally and killed Henrys wife in cold blood with a gun, shooting everyone else in the frenzy and attempting to kill Henry before he was distracted by Vicky Vale taking his picture, allowing Henry to escape. He chases after the reporter and would have killed her had Batman not shown, never the less he managed to avoid capture. Using thorough detective work Batman was able to deduce Abbatoirs link to the Etchinson family and where he could find the villian. He managed to track Abattoir to his familys cemetary and after a brief confrontation Etkar was eventually captured. It turned out that it was Henry Etchinson himself who had arranged for the lunatics escape because he wanted Abbatoir to come after him during the rally in the hope that it would gain him puplicity for the election if he survived the killers rampage. It was also revealed that Henry's wife was filling for divorce and that he wanted Abattoir to kill his wife to avoid any bad press the divorce would bring. As a result Henry Etchinson was sent to prison and Abbatior committed to Arkham Asylum. When Bane sets all the inmates free from the asylum, Abattoir flees and goes on to kill several more family members shooting then skining them ,Abattoir then tracks down his cousins son (Graham) who was orphaned as a result of his fathers incarceration and currently works at Doctor Thompkins Orphanage. While Graham is preparing to take a group of oprhans on a camping trip Abbatoir manages to comandeer their bus after posing as the driver (who he had killed earlier). Whilst driving them away far enough for anyone to find them Abbatoir revealed himself to Graham brandishing a gun and prepares to kill his cousin as well as the 12 orphans whos "Souls" he would "consume" however Batman's replacement, Azrael, catches up with Abattoir and the two battle on the roof of the bus. Unfortunately as it was snowing the bus lost control and nearly crashed off the edge of a cliff, while Azrael got the better of Abbatior in battle Abbatoir fell off the roof and managed to escape after the snow gave him a soft landing sliding off the cliff. With the bus dangling off the edge Azrael was left with the dilema to persue Abbatoir or save Graham Etchinson and the childeren. Ultimately Azrael chose to save the childeren and managed to pull the bus back up to safety with a combination of his grapple tied between the bus and a tree and his strength, by which time Abbatoir had managed to escape on board a oncoming train. Abbatoir later came after his nephew again and managed to kidnap him after being aided by Preston Payne (due Abbatoir holding Paynes son hostage as leverage). Etkar then strapped his nephew in a torture device before having to escape from Azrael again who chased him into a refinery. Inside the refinery, Abattoir is nearly knocked into a vat of molten metal, but hangs on to a plank. Azrael does not save Etchinson, but allows him to fall to his death. Unknown to Azrael, Abattoir had kidnapped Graham Etchinson, and was keeping him in a hidden torture chamber. By allowing Abattoir to die, Azrael had condemned the innocent man to death.
Abattoir eventually returned as a ghost in an attempt finish his mission of killing relatives. He was trying to scare his last blood relative, a cousin, into a miscarriage. Batman, now back to full health and in his rightful role, confronts the ghost. Abattoir attempts to torment Batman, using Azrael's armor, but Batman proves to be unaffected. Batman eventually tricks Abattoir into abandoning the armor and his mission.
During the Blackest Night, Abattoir was raised by a black power ring and became a Black Lantern.
Batman was investigating a string of kidnappings. The kidnapper has been abducting members of Gotham's elite as well as those who are well educated. Dr. Adrian Kohut, a psychiatrist at Arkham who was treating Harvey Dent with his multiple personality disorder, is the latest victim of this elusive kidnapper. Batman observes Kohut's office while Gordon checks for any patients that might have a grudge against the doctor. Batman finds a fiber that matches a special napkin used at restaurant called Chez Nous. The restaurant was closed for renovation but Batman knew immediately that he was in the right place because he found the clothes of all the other victims hanging in the coat check room. It made sense now to Batman why so many victims had disappeared and no ransoms were made... the kidnapper was devouring his victims.
Batman continues to investigate until he smells something delicious. He then notices a covered dish on a nearby table. Batman lifts the lid and is shocked by the mere sight of it. The kidnapper has taken someone's brain and sauteed it with a poached duck egg. Batman feels he is too late to save Kohut until he hears a noise coming from the kitchen. Batman races toward the kitchen and finds the decapitated head of Ben Cormicle, the head chef at Chez Nous. Batman continued to search the kitchen and finds Adrian Kohut hanging in the freezer with a meat hook protruding from his right shoulder. Batman calls in Gordon to investigate the crime scene while he acts on a new lead. Before Kohut went into a catatonic state, he told Batman that the kidnapper was after another potential victim. Gordon calls in Wallace "Wally" Camp, one of the precinct's csi's, to investigate the crime scene.
Batman makes his way to Prospect Park where the Wayne Foundation has renovated old brownstone buildings into livable homes. Dr. Bako Su, is a psychology professor at Gotham University and he becomes the kidnapper's alternative victim since he was unable to consume Dr. Kohut. Dr. Su tries to reach out to the kidnapper but the cannibal slaps Su because there are too many people talking. Dr. Su suspects that the kidnapper suffers from a multiple personality disorder but he is unable to get in contact with anyone since all personalities are fighting for control of the kidnapper's body. Batman arrives just in time to combat the cannibal but kidnapper feels so rushed by the Batman's interference that he takes his frustration out on Su. With the flick of his wrist, the kidnapper grabs a butcher's knife and slits Dr. Su's throat. Batman tries to keep Dr. Su from bleeding out but fails to save him.
Batman returns to the Batcave and suspects that the killer practices Maori which is a social cannibalistic ritual among tribal warriors who celebrate their victory over their enemies. The killer put a tribal tattoo on his face in order to conceal his identity but Batman figures its a way to deal with the guilt and shame of his actions. However, the one thing that troubles Batman is the Maori connection with this new Abattoir because the killer possesses gymnastic and surgical precision skills. Batman goes back to the beginning of these Abattoir slayings and recalls two particular victims. One victim was Eddie Campbell, a parkour master and stuntsman. The other victim is Dr. Antonio Bayless, the former head of surgery at Gotham Hospital. Batman doubts it but its possible that the Abattoir is killing particular people in order to possess their skills and knowledge. Ultimately, this new Abattoir is troubled by multiple personalities and he knows it which is uncommon for those who suffer from this disorder.
Alfred then reminds Bruce that he must go to Orange Interior, a high end home catering boutique and go see his decorator about a Paul McCobb desk. Meanwhile, Gordon investigates another murder in Crime Alley. The Abattoir killed a transvestite named Anthony Della Russo. Gordon asks Bullock where Wally Camp is but Bullock reports that Officer Murphy and Camp have been having problems with their relationship. Becca Proust

PERSONALITY AND BELIEFS
Perhaps one of the most disturbing aspects of Etkar was his lack of appathy, while his primary victims were his family members Etkar had no qualms with killing civilians as well , as a matter of fact he seemed to equally relish in slaughtering them just as much as his family. He would often get a kick out of torturing his victims first or the very least terrifying them, such an example was his treament of his nephew Graham Etchinson whom Abbatoir strapped to a Bed of Spikes with weights dropping vertically above grahams chest. ( The mechanism was designed to drop one weight every 2 minutes resulting in a slow and painfull death for his nephew.)
Etkar strongly believed in the supernatural, in paticular the possesion of the human soul. He believed by killing a human he would posses their soul and gain their strength making him more powerful. Oddly enough Abattoir actually aquired these abilities twice after his death . The first as a reanimated Ghost trying to consome his last living cousins unborn childs soul, The second during the Blackest Night storyline when his corpse was reanimated as a Black Lantern
