### Voice actor

Roger Craig Smith (Arkham Origins)Kevin Conroy (Arkham Asylum, Arkham City, Arkham Knight)Kimberly Brooks (child)

When his parents were gunned down in front of him, young **Bruce Wayne** resolved to rid Gotham City of the criminal element that took their lives. He trained extensively to achieve mental and physical perfection, in addition to mastering martial arts, detective techniques, and criminal psychology. When he returned, Bruce was inspired by a bat in his ancestral home of Wayne Manor. He then became **Batman** who fought crime with the aid of specialized gadgets and vehicles and operated out of a secret Batcave underneath Wayne Manor. Batman led a successful twelve-year, crime-fighting career until he was publicly unmasked by Scarecrow during the Arkham Knight Incident. Following the incident, with his identity fully exposed, Batman initiated The Knightfall Protocol and disappeared from the public eye. Despite that, his legacy lived on with the citizens of Gotham.

## Incident Report's

### Road to Arkham Asylum Incident

Batman was notified about an anonymous tip that was left in Dr. Sarah Cassidy's Office at Arkham that revealed that she had been kidnapped by Zsasz and taken to the Old County Hospital. Batman took Zsasz out by surprise and rescued Cassidy from his clutches. In the same month, a second tip came in the form of a note attached to a test tube. Unsurprisingly to Batman the tube contained an extremely potent, colorless, and odorless Fear Gas. It was similar to Scarecrow's Fear Toxin, but was much stronger.

While experimenting with it in the Batcave, a few molecules escaped from the vacuum seals and caused Batman to fight his way out of a series of fears and hallucinations. Batman was able to create an antidote from the formula and ambushed Scarecrow, attacked the psychologist, took him back to his cell, and cured his victims. The GCPD received the third and final tip in the form of a 911 call that arrived moments before the Joker raided Gotham City Hall and took the Mayor hostage.

The Joker strapped the Mayor to the side of a large pillar on the roof of the building and attached a bomb to his waist. Batman destroyed the Joker's detonator and removed the bomb before it exploded. The Joker attempted to escape with a parachute, but Batman easily thwarted the villain. While escorting the Joker back to Arkham, he spoke with Oracle through radio and vocalized his suspicions on the three tips and whether they came from the same source, as well as the easy nature of the Joker's capture. Despite these suspicions, Batman drove the Joker back to Arkham and hoped that they would disappear once he was back behind bars.

### Arkham Asylum Incident

Batman arrived at Arkham in the Batmobile and took the Joker to the Intensive Treatment Center. Activating the Batmobile's defense systems, Batman took the Joker inside to be processed. However, the Joker remained in high spirits and was pleased that he was back in Arkham. Feeling that something was wrong, Batman told Warden Sharp that he will be following Joker to his cell. Officer North also informed him that commissioner Gordon is waiting for him on the lower levels, which is where the Joker's cell was held.

Joker was strapped to a prisoner movement trolly and wheeled through the Intensive Treatment lobby by a variety of security guards, including Frank Boles, with Batman following close by. The Joker commented on all the brand new security at Arkham, which would make it harder for him to break out; he then pointed out the coincidence of a fire at Blackgate Prison, resulting in hundreds of his goons over to Arkham along with other thugs. Batman took the hint, immediately realizing the Joker was planning something and was just waiting for his chance to escape. He questioned Joker as to why he let himself be caught so easily, asking what he's after; all he got in return was a taunt - "Oh, nothing much. Just hundreds dying agony and suffering. All thanks to you and a book of matches. Is that the answer you wanted?" During the escort, Joker made snide remarks to many of the Arkham Staff: Warden Quincy Sharp, Officer Aaron Cash, and Dr. Penelope Young before being taken down the elevator.

During the elevator journey, a temporary blackout happened. Guards panicked as the Joker laughed hysterically before the restored lights revealed that Batman had restrained him by the neck. As the Joker was moved into the lobby area, he was unstrapped and escorted by a guard and an orderly while Batman and Commissioner Gordon looked on. Batman could not be allowed past that point, as there were many patients who could be upset by his presence. That was when the Joker made his move.

Batman could only watch as the Joker broke free and killed the unsuspecting doctor and guard as the Dark Knight pounded his way through a re-enforced security window. The Joker escaped. Harley Quinn had taken control of Arkham's security system the entire time he'd arrived. For his first trick, the Clown Prince of Crime had released several nearby thugs from the their cells. After Batman had easily defeated them all, the Joker made his way to the Patient Transfer Unit, and goaded Batman to follow him.

Batman followed the Joker through the depths of the Intensive Treatment Center and found a trail of destruction that was littered with deceased Arkham security guards. Batman halted briefly to defuse a hostage situation in the Patient Pacification Chamber, where an escaped Zsasz had taken a security guard, Mike, hostage and had strapped him to an electroshock chair. After taking down Zsasz, Batman was greeted by Harley via the hijacked asylum monitors, taunting him and showing off Sharp, her new hostage. Batman left the Patient Pacification Chamber through the ventilation system, followed Joker's trail of spray painted smiles and arrows, and confronted the villain in the Secure Treatment Transfer area.

The Joker opened up a large patient transfer cell and released a large experimental monster (bearing a resemblance to Amygdala). The monster attacked Batman before dying of an apparently simultaneous heart attack and brain aneurysm, much to the Joker's annoyance. As a result, the Joker offered one free shot, goading Batman to knock him off his perch and into a lethal fall, ending the madness. Batman drew a Batarang but hesitated, still unwilling to kill his enemy. The Joker laughed and dubbed him as "too predictable". As the Joker escaped via the Patient Transfer System, he announced that he was organizing a "party" with the villains all over Arkham. While Batman tried to get the transfer unit working again, the Joker appeared on a monitor and showed Batman an image of a treacherous Frank Boles knocking out Gordon and taking him hostage, ready to kill him should Batman follow him.

Batman attempted to track down and rescue Gordon, by using his cowl's Detective Mode to detect alcohol traces from Boles's bourbon flask that was left in the air. Along the way, Joker left traps with Joker Venom as well as many gag chattering teeth. Navigating the elevator shaft and returning to the Intensive Treatment Lobby, Batman finally caught up to Boles, only to find his corpse strapped to a gurney, and having outlived his usefulness, and no sign of Gordon. Batman was contacted by the Riddler who had hacked into his communication system to challenge the Dark Knight to solve his riddles and challenges and to collect the Riddler Trophies that were placed all over Arkham Island.

The Joker took control of Arkham's intercom system, and told his goons to destroy the Batmobile as he took over the West side of Arkham Island. Batman contacted Oracle, and told her to disable the car's defenses in case her father was with them. The wrecking crew didn't have Gordon, but Batman found the Commissioner's pipe, which was a birthday gift from Barbara, and a trail of Wild Country Tobacco. Batman was able to isolate the tobacco trail with his Detective Mode: a sign that Gordon had left to show he was still alive. After he had retrieved a supply of Explosive Gel from the Batmobile's trunk, the Dark Knight resumed his search.

The forensic trail suggested that Gordon had been dragged to the Medical Facility, which was under siege by the Joker, and he ordered his goons to round up all the doctors in the area, specifically Dr. Young. Batman defeated the goons and proceeded to rescue the captive doctors and Officer Cash. Dr. Young insisted on returning to the Arkham Mansion to retrieve her notes. Cash offered to escort her, despite Batman's misgivings. Batman then took out another raiding party of thugs before taking the elevator to the lower levels to follow Gordon's trail. He found the place under the control of Scarecrow, and the murdered body of Commissioner Gordon. His mind reeling from one his greatest fears, Batman was confronted by the animated corpses of his parents and a twisted obstacle course overseen by a giant, omnipotent Scarecrow. Realizing that he was experiencing a Fear Toxin Hallucination, Batman overcame the delusion, finally tracked down Gordon, and rescued him from Harley in the Experimental Chamber.

Batman admitted he wasn't sure that he could stop the out of control Joker this time, but Gordon had reassured him he would, and suggested that they examined something mysterious that Joker was keeping in the holding cell below them. They found Bane, though not as they had known him. The giant was emaciated and hung from the ceiling by his Venom tubes, and was drained of Venom for days, by Dr. Young, rather than the Joker. The Joker was more than happy to take advantage of the situation, however, pumping Bane full of a new formula that restored him to his TN-1 induced size, and had seemingly made him even more powerful. The two then fought in the Boiler Room. Batman had managed to dismantle Bane's delivery tubes before escaping as the ceiling came down on them. Batman was afforded only a temporary respite as a still fully powered Bane smashed his way to the surface and vowed to first break Batman, and then Dr. Young. Batman told Bane that he would be broken this time, remotely crashing the Batmobile into Bane and sending both into the ocean.

Sending Gordon back to Gotham and relative safety by boat, Batman headed to the secret Batcave that he had built at Arkham's infamous Dead Man's Point years ago. There, Oracle sent him files that she had hacked from Dr. Young's computer, and shed light on the Joker's latest scheme: Young had been working on "Project Titan", an experimental chemical treatment to repair possible brain damage. Derived from Bane's Venom, the process instead had the potential to create super strong monsters that were twice as powerful as Bane. Young had learned who her benefactor was, and attempted to shut down the process, so Joker had staged an entire crime wave and his own capture to take over Arkham in order to take control of the Titan himself. Batman's objective was now clear: find and destroy Dr. Young's missing Titan Formula before the Joker could create an army of a thousand Banes.

Heading through the catacombs beneath Arkham, Batman headed for the Arkham Mansion in search of Dr. Young, and found it overrun with Joker's men. After he freed a captured Cash, Zach Franklin, and several other hostages in the Records Room and the Library, Batman resumed his search, and accessed Dr. Young's Office to search for the formula. Security footage from her computer was promising; she had already hidden the formula somewhere else. Setting up Detective Mode to isolate her recent fingerprints, Batman traced the evidence back to the Library, found the written formula hidden in a book, and destroyed it. The Joker wasn't outdone yet, however, and sent Zsasz after Dr. Young. Batman raced off to find her, but was gassed by Scarecrow again, and trapped in a hallucination of the night that his parents were murdered. He managed to free himself a second time, but was too late to prevent Zsasz from taking Young hostage in Warden Sharp's Office.

Batman incapacitated Zsasz and rescued the doctor. A distraught Young lashed out at Zsasz, the night's event taking their toll. Batman managed to calm her down enough to get her to explain about a chemical production facility that was hidden in the Asylum's Botanical Gardens, which Joker would be sure to use to produce Titan when she was forced to surrender the formula. She explained that Batman would need Warden Sharp's security codes to access it, and was about to retrieve them from his safe, only to come face to face with the spray painted face of a Joker booby trap. Batman was powerless to save her, and was knocked out in the blast that had killed Young.

Coming to, Batman was taunted by Harley who beat a still captive Sharp with his own cane before leaving the Dark Knight with a few thugs to "prepare" him for the party. Batman made short work of them, and scanned a sample of Sharp's DNA from the blood smears on the broken cane head in order to track Quinn down. The trail led to the Penitentiary, where Batman was accosted by a still imprisoned, but hysterical Poison Ivy in her cell. Ivy begged Batman to help her plants, and claimed that they were in pain, an insanity plea that he had naturally ignored, and told Ivy to remain in her cell. He tracked Sharp's DNA trail to the Penitentiary's Security Control Room where Sharp was tied up in the control booth. Batman was also taunted by an imprisoned Clayface who was impersonating Cash, then Sharp, and finally, Gordon, but wasn't fooled into releasing the shape changer. Batman freed Sharp just as the Joker cut in with the video footage of Harley freeing Ivy and his release of all the truly insane inmates from the cell block to wreak havoc and, to add insult to injury, locked Batman and Sharp in together. Batman demanded Sharp's code sequencer, despite Sharp's protest that it was useless without the destroyed terminal in his office. Batman improvised by simply plugging it into his Cryptographic Sequencer, which allowed him to overload all of the security terminals throughout the asylum and disabled the numerous barriers that Joker had placed in his way. He told Sharp to stay where it was safe as he went after Harley, and the warden was all too happy to oblige.

Batman confronted Harley in the cell block, defeated the thugs that she had thrown his way, and disabled all the electrified floor panels that she had used to slow him down. He chased her into the Guard Room, and found Louie Green and another guard suspended over electrified water with a bomb of Joker Gas that was rigged to detonate. Batman was able to get both Green and the other guard out safely before the bomb exploded. He followed Quinn to Extreme Incarceration, and once again dealt with her goons and electrified floor. Harley's failure prompted Joker to remove her from the 'Party List'. Batman defeated Harley, took her party list, locked her up, and used her DNA traces from around the island to track Joker to the Botanical Gardens.

Chasing Joker, Batman ended up in the sewers underneath the Botanical Gardens, where he heard the Clown Prince of Crime experimenting with the chemicals for the Titan formula. Overhearing the Joker welcome and inject a henchman with his latest batch, Batman learned that Joker hadn't perfected it yet. The corpse of the failed Titan Henchman was tossed down into the sewers, where Batman examined it ; only the thug's arm had been enlarged by the formula, which was still coursing through the body. As the route to the Glass House was gone, Batman was left with the route to the Aviary, which is where the Joker had to be. Joker forced him to play a deadly game in the Aviary, by stringing a pair of orderlies, Luke Curtis and Robert Stirling, in birdcages over a deadly chasm and challenged Batman to rescue them as his men patrolled the area.

Batman was successful in the hostage situation, re-discovered Harley's trail, and hacked into the Titan Production Facility's secure entrance which had slowed him down just enough for Joker to perfect his Titan Formula. Batman watched as the Joker demonstrated by injecting two of his thugs and left them to attack Batman, with an elevator full of Titan. Batman defeated both of the monsters and pursued Joker, and passed by the dead bodies of Stirling and Curtis on his way back through the gardens; Joker had murdered them along the way, making their rescue pointless. Batman realized that in order to stop Joker, he would need an antidote. The only person on Arkham who had intimate knowledge of plants now was Poison Ivy, whom Batman knew he would be able to force into cooperating if he threatened the plants.

Having the Batwing deliver the Line Launcher, Batman headed to the Glass House, where Ivy was nursing the plants. After destroying a plant (which hurt Ivy, do to be disconnected from nature too long), Batman was able to get Ivy to tell him where he could find the antidote; plant spores capable of counter the Titan were in the sewers, which now served as Killer Croc's Lair. Leaving the Botanical Gardens, Batman overheard Joker on the intercom; the clown gave Ivy two injections of Titan, causing her to become far more powerful and take control of the island surface with her evolved plants. Batman located Cash in the Arkham Mansion and was told by him that there was another door to Croc's Lair at the Intensive Treatment Center.

Oracle called him about the seismic activity on Arkham, which he explained was due to Ivy forcing her plants throughout the island; as of now, she controlled Arkham East, and was working on taking over the rest of the island. Batman was warned that if Ivy's plants get off Arkham, the damage they could due to Gotham was incalculable; he vowed to not let happen. He formed himself in the Intensive Treatment lobby, which had been booby-trapped to prevent him from using the gargoyles; taking out all (or enough of) the thugs, Batman was able to hack into the door controls and release the barriers leading to the elevators. To Batman's confusion, he heard the intercom ask if anyone saw last night's game before his vision became blurry and heard the Joker's distorted laughter coming from around him.

Batman then saw a surreal deja vu of earlier that night, but with himself in Joker's place and the staff under the mercy of the Blackgate thugs. After being shot by Joker, Batman realized that he was under the effects of the Fear Gas again, fighting off the effects, and grabbing Crane by his hood. However, Crane jabbed him with his syringes, causing Batman to fall into another hallucination. However, Batman's will proved stronger than the Fear Gas, surprising Scarecrow, who proceeded to flee into the sewers. Batman followed after him, as Crane threatened to drop a pouch of Fear Toxin into the water supply, poisoning Gotham with its effects for 100 years. However, Croc emerged from the sewage and attempt to eat Crane. Batman tossed a Batarang at Croc's shock collar; this saved Crane, who was dragged into the sewage by Croc.

Batman proceeded into the maze-like tunnels Croc lived in, taking samples of the anti-venom spores. As Croc had mentally devolved into a dimwit at this point, Batman was able to trick him into a trap, which dropped Croc into a lower level of the sewers, allowing Batman to head back to the Batcave. After a batch of the antidote was made, Batman programmed his computer to make more; unfortunately, Ivy's plants grew through the walls of the cave, destroying the computer. Batman returned to the sewers, finding that Joker wanted to pollute Gotham with the Titan by-product as a backup plan in case his army couldn't get to the mainland. Batman took out the three pumps before heading back up to the surface, which was now glowing red from Ivy's spores.

Ivy's voice could be heard coming from all over, as she yelled at Batman for harming her plants. Annoyed at her for constantly babying vegitation, Joker asked over the intercom if she ever shut up about plants. Ivy returned his annoyance with the threat to go after him once Batman was dead. Joker assured her that he would be prepared for her with an army of Titan monsters, and said the she could "bring the wine" and he would "make the salad". Batman had managed to defeat Ivy in the gardens by using his Explosive Gel to blow Ivy's protective shell that caused her plant to go out of control.

With all of the enemies on Joker's 'party list' defeated, Joker had his men set off fire works and directed Batman, the 'guest of honor', to the 'party' at the Visitor Center by the Cell Blocks. Rather than fight Batman, upon his arrival and confirmation of being on the 'guest list', the goons acted friendly, cheered him on, and even allowed him safe passage. Batman found a bomb planted by Joker in the Visitor Center and upon its explosion, discovered the Joker's Lair: a throne room atop various plastic toys from which he had been broadcasting to the island.

Joker was holding Scarface, the puppet, and took out his frustration on him by having a fictional argument with him before throwing him away. He then sent two more Titan powered thugs at Batman, who defeated them. Joker then revealed that he had recaptured Gordon. Firing a Titan strain at Gordon, Joker was overjoyed when Batman took the shot himself. However, he was angered when Batman had resisted and had fought off Joker's attempts to make him give in. Joker then claimed that he had nothing to live for, as Batman would not allow him victory, and shot himself in the neck with his Titan injection gun, and comically acted as if he was committing suicide.

Joker quickly awoke and mutated into the most horrific Titan monster, while still retaining his regular intelligence due to him already being insane. Joker then directed the circling Gotham News helicopters and Jack Ryder to the rooftops of Arkham so that they could watch his final fight with Batman. Strapping Gordon to an electric chair above a makeshift fighting arena (making him the "referee"), the mutated Joker goaded Batman to give into his injection, as it was the only way they could be on even fighting terms. Batman refused and used the only antidote injection on himself, which the Joker found hilarious. The two, with assistance from Joker's henchmen, then fought a brutal battle, with Batman knocking Joker into the electrical generator that was used to torture Gordon.

The Joker got up from the attack and said he could take anything that Batman threw at him, and asked if the Dark Knight was ready for the next round. Spraying Explosive Gel onto his glove, Batman declared that he would never let Joker win and would always be prepared for his tactics. Enraged, Joker prepared to kill his relentless nemesis as Batman charged him. The gel on Batman's fist fiercely knocked Joker down as he was punched in the face. The GCPD then retook control of Arkham Island, imprisoned all of the inmates back in their cells, and watched over the Titan injected thugs as they returned to normal. Joker's transformation back to humanity was quite painful compared to the others, culminating with the severe injuries he received. Joker was then securely locked back up, his plans having ultimately failed.

Outside the Visitor's Center, Gordon told Batman that the effects of Titan were starting to wear off the Joker and his men, and that they were all being taken back to their cells. Batman was informed that Two-Face was raiding the Second National Bank of Gotham, and flew away into the night in the Batwing to the scene of the crime.

### Before *Arkham City* Incident

Batman remained adamant in his search for Crane or his corpse, not believing that he was dead until a body was found. However, all his searching proved fruitless, as Crane was too good at hiding himself.

Six months following the Joker's rampage at Arkham Asylum, Commissioner Gordon informed Batman that Joker's Titan Formula had found its way into Gotham City and had turned up in the form of the brother-sister team: T&T. Wasting no time, Batman correctly suspected Two-Face to be T&T's previous employer, based on the fact that a pair of mirror images like T&T working together would be prime candidates for recruitment into Two-Face's Gang.

Tracking him down to one of his old hideouts, Batman discovered Two-Face had been beaten, battered, and broken. Two-Face revealed information about T&T in exchange for a 30 minute head start. He explained that shortly after the Joker's rampage, crates full of Titan had washed up in the docks where Two-Face had bought them. Two-Face made the mistake of having T&T bring the crates into storage in his cellar.

Over the past six months, T&T had experimented with the drug in small doses, thereby gaining control over themselves in their Titan forms. Two-Face also stated that T&T had slaughtered his gang and that the rest of Gotham was next. At Sharp's new town hall dedication ceremony, T&T attacked, and Batman arrived to stop them. Perhaps getting the idea from his last fight with the Joker Batman had installed gel sprayers on his costume which gave his strikes extra power.

During the fight, Batman overheard T&T being given orders over their radio. Before Batman had the chance to apprehend and interrogate the duo, they had committed suicide via surgically implanted explosives, killed hundreds in attendance of the press conference, and destroyed the rebuilt Gotham City Hall. Batman began to believe that T&T were working for someone who was in cahoots with Sharp, and thus infiltrated his mansion, which had doubled as a temporary city hall.

There, Batman used Sharp's personal files to check in on his past, and revealed that Sharp was essentially a schizophrenic blank slate, who was extremely vulnerable to suggestion to the point that he had to be told to hang up a phone in order to do so. At this point, Batman was assaulted by non lethal weaponry, which lead him to conclude that this was a trap that was meant to study him.

Choosing to deny his opponent his triumph, Batman fled the mansion. Meanwhile, Harley successfully broke out the dying Joker from Arkham Asylum, and despite Batman's best efforts, they had successfully escaped to Arkham City.

Later on, Batman disguised himself as a small time street thug who was named Lester Kurtz and with the added help of Oracle, who had planted a criminal record into the GCPD database, infiltrated Arkham City where he had learned of a rising gang turf war between the Joker and the Penguin who were willing to slit the others throat to be the top dog in Arkham City.

As a test of the Lester Kurtz identity, Batman infiltrated and temporarily joined both gangs and assured that the Lester Kurtz identity was safe, because neither Joker nor Penguin, two of his old enemies who knew him best, had figured out the Lester Kurtz identity. In the process, he had destroyed an arms shipment that was meant for TYGER that they were both after.

Unfortunately, it seemed that in a matter of hours, the Lester Kurtz Identity was compromised when Batman walked into a trap set by Sharp's accomplice who used the TYGER Guards. Batman discovered that the TYGER Guards had been extensively working out specifically to match Batman in a fight and had been given impact absorbing armor in order to lessen his super-charged punches.

Batman was only saved by the timely arrival of Catwoman who was revealed to have already hijacked the weapons shipment and freed Poison Ivy from TYGER custody. Batman left Catwoman to her business and went to get some answers. He captured and interrogated a TYGER Captain into revealing the true identity of the one of was pulling the strings in Arkham: Hugo Strange.

Mere hours after this discovery, Batman instructed Robin and Alfred to dig up all that there was to know on Hugo Strange so that he, as Bruce Wayne, could publicly reveal it. Strange was a step ahead of the Dark Knight, however, as he had Sharp announce his involvement in the Arkham City Project so that he could paint a positive image of it and also give him an alibi for his actions. Arkham City opened on schedule and went unopposed.

Eighteen months after the Joker's takeover of Arkham Asylum, Quincy Sharp was elected the Mayor of Gotham City, and claimed to be the one who was responsible for ending the Joker's control of the island.

Shortly after assuming the role, Sharp declared that both Arkham Asylum and Blackgate Priison were uninhabitable, and ordered the construction of Arkham City on the southern banks of Gotham against the better judgement of both Batman and James Gordon. Batman believed the project to be a ticking time bomb and kept a watchful eye on Arkham City for months, and looked for any excuse to break into the well-guarded prison city

### Arkham City Incident

Come mid-winter, Batman convinced Commissioner Gordon to have someone with the finances and influence needed to lead a protest against Arkham City; he suggested Bruce Wayne, to which Gordon agreed to. Calling a press conference in front of the gates of Arkham City, Batman arrived fashionably late as Bruce Wayne. With both Vicki Vale and Jack Ryder covering the event, Bruce proceeded to explain that gang leaders were leading a violent and bloody war behind the walls of the prison; if nothing was done soon, the war could erupt into the rest of Gotham. However, TYGER guards then swarmed the scene, scaring off the audience and knocking Bruce out.

Bruce was awakened by a Stun Baton, finding his hands and feet shackled. He was now face-to-face with Hugo Strange. Trying to talk sense into him, Bruce learned to his horror that Strange knew he was Batman. Strange claimed Protocol 10 would make him famous, vowing to reveal Batman's identity if Bruce tried to stop. Bruce attempted to escape, knocking down a TYGER guard and discreetly taking a communications chip from his radio. However, back up arrived and violently retaliated, forcing Bruce to comply with their orders. Brought to the exit for insertion into Arkham, Strange told Bruce his cuffs will remain on as he didn't want things to be too easy for him; he bid Bruce farewell, doubting they would meet again.

Locked between doors, Bruce found Jack Ryder was also with him; telling Ryder to stay calm and near him, Bruce was ignored the moment the door opened. Despite his handicapped state, Bruce fought off attackers, pulling Ryder up to walk into Arkham City.The gates opened to reveal Penguin waiting for him. Bruce was knocked out from behind by one of his henchmen, using a bat.

Awakening, Bruce acknowledged Cobbleport, who proceeded to beat him with brass knuckles as revenge for the collapse of hist family's empire. However, Bruce broke his hand instead. Breaking out his restraints, Bruce knocked out the Penguin's men and headed to higher ground to contact Alfred via a radio in his watch. Bruce informed his old friend that Strange knows his secret identity. He then order that his Batsuit and equipment be dropped off on the Ace Chemicals rooftop via Batwing.

Once suited up, Batman added the TYGER chip to his Cryptographic Sequencer, allowing him to hack into their communications. He learned over the radio that Catwoman was trapped in the Solomon Wayne Courthouse, which served as the lair of Two-Face; Dent was planning on killing her. Strange found the situation amusing, ordering TYGER to do nothing to assist. Infiltrating the building, Batman watched as the two personalities of Two-Face fought over whether to give a proper trial to Selina; Harvey won the coin toss, starting a kangaroo court. Two-Face was looking to use the execution of Catwoman to rally more inmates to his gang, in the hopes of gaining enough forces to slaughter Penguin and Joker's gangs.

Batman took out a sniper watching from the third floor, leaving only Two-Face armed. After Two-Face gave the case to his court, Batman surprised the thugs, scaring off the recruits, while a small batch of thugs remained to fight him. Once the goons were taken care of, Batman suffered a gunshot to the chest from Two-Face; the impact against the armor knocked him down. Two-face then attempted to kill Selina, who easily escaped and damaged to good side of his face, knocking his gun away.

However, once Two-Face pulled his second gun out, Batman recovered and used his Grapnel Gun to tie him up and leave Dent hanging over the tank of acid in a sense of irony. An enraged Two-Face demanded to be let go and fought fairly as this was a coward's move; he also voiced his belief that fate was all that stood between him and killing Batman.

With Dent tied up, Batman questioned Selina about Protocol 10, learning that she has no idea what it is. However, she then told him about how the Joker had secretly been plotting with Strange, on something every special just for Batman; it was her guess that this was Protocol 10. Batman then noticed a sniper laser pointing at Catwoman's head and grabbed her out of the way of being shot. Realizing that only Joker would do this, since they were talking about him, Batman warned Selina to stay out of trouble. Catwoman ignored his warning, as she liked the danger that was abundant in Arkham City. Tracing the trajectory of the bullet, Batman was able to deduce that the shot had originated from the bell tower from the Gotham City Cathedral, which had been transformed into the Arkham City Medical Center. He left the courthouse via the back entrance as Two-Face's thugs were holding the fronts doors shut. The basement held Calendar Man in cell, mumbling about holidays.

Batman found prisoners in uniforms similar to Jack Ryder's, deciding to question them. They weren't criminals, but instead Political Prisoners sent in Arkham by Strange; they had worked on Wonder Tower or on the security wall, posing a threat to Strange as they knew Arkham City's secrets. Batman found more by Live Nudes; he learned they hid until daylight to search for food, as the gangs would kill them otherwise. He also saved Jack Ryder, learning Ryder discovered a patient who claimed Strange caused his breakdown and made him forget his own name. Batman remained on the look out for more Political Prisoners being attack by the inmates, usually asking unreasonable things as they weren't hardened criminals like the rest.

Near the courthouse, Batman found a mysterious stranger waiting for him on a roof; the stranger claimed to have been watching him for a long time. He vanished in a puff of smoke, leaving a symbol behind for him to scan; Batman remained on the lookout for the stranger throughout the night. Batman headed to the cathedral, but overheard some prisoners talking about a payphone killer as they debated over answering a ringing phone. Scaring them off, Batman answered the phone and learned Victor Zsasz was the mysterious killer; he vowed to kill three captives if Batman couldn't find and answer the payphones he was calling in time. Zsasz bounced his signal around the relays of Arkham, but Batman had the WayneTech satellites triangulate the signal every time he called.

Later, Batman confronted Harley and her thugs who took the staff hostage. Harley left, taking one of the medical team, Dr. Stacey Baker, to help the Joker After he had rescued the members of the staff, Batman went to the bell tower to investigate the scene and to determine the Joker's location and get answers that regarded Protocol 10. Batman discovered that the gun was controlled by Joker and escaped from the bell tower explosion that was set off by bombs by the Clown Prince of Crime.

Tracing the signal Joker used to remote control his puppets, the Dark Knight traveled to the Industrial District, which had since become the Joker's territory in Arkham City. At the same time, the WayneTech satellites had pinpointed Zsasz's hideout to this area, so Batman broke in and incapacitated Zsasz. However, he found out Zsasz had broken his promise and killed the third hostage in the meantime.

Back outside, Batman headed for the Sionis Steel Mill. Seeing there was no other way in, Batman grappled into the chimney and managed to land safely on the guard-rail. Using the ventilation systems as cover, Batman observed as Harley ordered the thugs to take Dr. Baker to the Smelting Chamber for further torture for failing to cure Joker. Batman surprised Harley by revealing her trap failed; she locked herself and Joker into the Manger's Office, which served as their room.

Batman headed to the Smelting Chamber, taking out the men guarding and torturing her. Untying the doctor, Batman is informed by Dr. Baker that Joker is far worse than the goons think he is; the fact Harley is giving orders means Joker is either in a wheelchair, or he is unwilling to appear weak in front of his goons. Batman wonders what caused this, only to learn the TITAN that Joker injected himself with back during the Arkham takeover is the source of his illness. Dr. Baker goes on to explain the toxin levels in Joker's blood are off the charts; he should be dead already, but is somehow clinging onto life. She also adds that Joker's deteriorating health has had a serious negative impact on Harley's mind; if Joker dies, what's left of Harley's sanity will go with him.

After returning to the Loading Bay, Batman confronted Mr. Hammer and Joker's thugs; he promptly defeats them. Hearing Harley wailing in despair, Batman heads to the Manager's Office, where he hears an ECG machine flat-line. Batman sees Harley weeping at the Joker's side. Using Detective Mode, Batman confirms that the Joker's heart has stopped beating; he tosses Quinn aside, hoping to examine the body better. However, he is grabbed from behind by a healthy-looking Joker, who gasses him. Wozzy, Batman watches as Harley clobbers him with a bat until he falls down, unconscious.

Batman awakens to find Harley about to take off his mask, but Joker tells her not to as it would ruin the fun between the two of them; Batman is also tied to wheelchair, preventing escape. Annoyed by the trick, Batman states that Joker's illness was all lie; however, Joker comes out of the shadows, showing a disfigured face, reminding Batman that there's A LOT wrong with him. Joker explains that his blood is killing him, and that he's given some to Batman; unfazed, the Dark Knight is fine with dying with the Joker. However, the Clown Prince of Crime explains that he has been shipping out crates of his infected blood for weeks, effectively ensuring that several Gotham citizens die with them.

Batman now believes that this is Protocol 10, even thought it doesn't appear to work in Strange's favor; poisoning Gotham would be counter-productive to someone wanting to be famous as the Dark Knight. However, the Joker tells him that he's never heard of it. Joker then explains that they're running out of time, and that a cure was so very close to being in his hands, only to be stolen from him. Batman assures Joker that he'll get the cure, before being pushed out a window onto the dock below the Steel Mill, unconscious.

Hearing a circus theme, Batman awoke to find a cell phone strapped to his chest; answering, he demands that Joker tell him where to find the cure. Joker explains that he commissioned Mr. Freeze to create the cure, but has not made contact with him for some time. Telling Joker that he'll get the cure, Batman smashes the phone and takes the chip with the memory functions from it, inserting it into his gauntlet to allow hands-free communication between the two of them. To Batman's annoyance, Joker proceeds to use this to leave him messages throughout the night, including a mysterious taunt about his detective skills.

Batman radioed Alfred, who sent Robin to investigate the case; 30 people were already reported as infected. While tracking the coldest point in Arkham City, Batman found the stranger waiting for him on top of the ferris wheel in Joker's territory; he left another symbol behind. discovers an SOS on the Gotham Event rooftop. Batman confronted the Political Prisoner and the prisoner was killed by a single bullet that was fired by Deadshot; Batman proceeded to stay alert for rifle shots. Seeing a flare at Krank co. Toys, Batman entered and found Bane. Bane explained that Joker managed to send twelve containers of the Titan formula off of Arkham Island before being stopped; Batman agreed to take out six of the twelve, so long as Bane did the same, warning him that betraying his trust is a bad move.

Back outside, Batman found Joker's men outside the old GCPD Building; they were celebrating their killing of Penguin's men and laughing about the ones holed up inside. Getting past them, Batman heard Penguin over a dead thug's radio; taking the chip, Batman added it to the Sequencer, allowing him to hack into Penguin's private radio channel. Taking out the remaining men inside, Batman interrogated the surrendering thug and learned that Penguin had Freeze imprisoned in his museum. Penguin decided to cut off the Joker's forces by blowing up the bridge connecting the Amusement Mile to Park Row and the Industrial District; this angered his men now trapped in enemy territory

Batman went to the Museum to face the Penguin, but first had to disable the security systems that Penguin had established that had interfered with Batman's equipment and uploaded to Alfred at the Batcave and Oracle at the Clock Tower. Following the signals, Batman found and disabled two rooftop jammers; however, he found that his signal was still being blocked. Listening to Penguin's private radio signal Puffin Zero, Batman learned that a third jammer had been activated underground. Heading into the train station, Batman disabled the final jammer, as Penguin barked threats to murder any of those who were left to guard the devices if they weren't already in terrible agony

Returning to the surface, Batman heard over the TYGER broadcast about a recently dead body near by. Investigating, Batman learned the M.O. matched the unidentified Identity Thief. Batman tracked the trail of blood from the victim to a Political Prisoner, who said a badly scarred Bruce Wayne dumped the body. This confused Batman, as he WAS Bruce Wayne and he knew that it was impossible.

Batman entered the museum, finding that the dinosaur exhibit had been re-purposed as a trophy room of sorts. There were displays for Two-Face and Joker's gangs (which including propaganda from their territories with the corpses of their goons), a copy of Scareface, TYGER guards (a corpse and equipmen), Zsasz (which was broken from the inside), Batman and Bruce Wayne. He found some of the thugs ganging up on one of their own; he saved the thug, learning that he was actually Elvis Jones, one of the ten cops that Gordon had sent into Arkham City at the beginning. Penguin found out who they were and proceeded to torture them all.

Leaving Jones with a gun, Batman proceed to a gladiator-like pit, where the Penguin watched cages of inmates fight to the death to earn the right to be in his crew. After seeing one of the cops killed, Batman vowed to bring down Cobblepot, who sent his potential recruits and a TITAN monster to kill him. Penguin retreated to the Iceberg Lounge, to let Batman face his traps. At this point, Oracle radioed him and Batman informed her about the TITAN that managed to get off Arkham island.

Batman headed into the next exhibit, which was a now flooded underwater-themed atrium; Penguin used Mr. Freeze's gun to freeze some of the water and encase three cops in ice. Using a density scanner, Batman saved the first cop and proceeded to use rafts in the water to save the other two. During this trek, Batman fought off Tiny, Penguin's pet shark. Batman proceeded into the right hall, which lead to the armory; he took out the goons and saved three more cops, leaving them to prevent the goons from rearming. Mr. Freeze's suit was here, meaning Freeze was in danger of dying if he was left outside of it for too long; Batman proceeded to look for Freeze next.

As there was only one other exit in the room aside from the Iceberg Lounge, Batman found this next hall filled with display cases of skeletons; the recordings explained that the skeletons belonged to thugs who either attempted to steal from Penguin, or make fun of him. Penguin had brutally punished these crimes by either burning them in an oven for hours or feeding them to Tiny. There was also a case for Buddy and Lou, the beloved pet hyenas of Joker; Penguin shot and stuffed them to take away something Joker loved.

Batman found Freeze in the Museum War Room, but was ambushed by Sickle, Mr. Hammer's twin brother, and Penguin's left-hand man (literally). After defeating them, Batman freed Victor from the exhibit; it also doubled as an oven, and was slowly killing the scientist. Batman demanded to know where the cure was; however, Freeze said to him that he didn't care as Cobblepot must pay what he's done to him. Batman demanded to know how to get past the cryo gun; however, Freeze wasn't willing to let his secrets be known by the Dark Knight.

Not in a pleasant mood, Batman removed the coolant that kept Freeze alive, forcing Freeze to reveal that he had an override chip in his suit that would disable the cryo gun. Hearing this, Batman laughed "and how did that work out for you?" before giving the coolant back to Freeze. Batman briefly returned to the armory, where he took the override chip and instructed a cop to give Freeze a backup coolant container, allowing him to return for his suit.

Batman headed to the Iceberg Lounge, where used the override, allowing him to punch to cockney geezer of his perch. Penguin proceeded to blow up the iceberg prop, dropping Batman into the cellar, which served as the cage for the un-dead Solomon Grundy. Penguin kept him charged with energy from generators in the ground; however, Batman blew them up and tore out Grundy's heart, leaving the zombie immobile. Penguin arrived with a grenade launcher, but was easily knocked out by Batman.

Batman returned to the trophy room, where he present Penguin to the now-armored Mr. Freeze; he had promised some payback for Freeze to enact. After letting Freeze step on Penguin's broken hand briefly, Batman allowed him to lock Cobblepot in a display case as both punishment and a sense of irony. With this business done, Batman demanded the cure. Freeze revealed there was no cure, as it broke down quickly after creation; it needs a restorative enzyme bonded to human DNA. After showing a specific DNA strand to Batman that the cure lacked, the Dark Knight quickly realized the DNA matched Ra's al Ghul's blood. Freeze explains a sample is all he needs to synthesize a cure; however, Batman points out the Ra's is dead. Though Freeze believed this meant they were doomed, Batman explained he just needs to ressurrect Ra's again.

One of the League of Assassins escaped from a display case, and left a trail of blood from a wounded shoulder. With this new info, Batman also proceeded to ask for the Line Launcher; he briefly joked with Alfred that he once considered a bigger utility belt, but had decided against it as it slowed him down. Leaving the museum, Batman proceeded to follow the blood trail; at the same time, Two-Face's thugs were threatening to takeover Penguin's territory.

Seeing the assassin's trail end with a cloth used to wipe off the blood, Batman decided to track new evidence, only to be attacked by the assassin, who he recognized as part of Talia al Ghul's personal guard. Batman managed to use close combat to place a tracer on one of the assassin. Willing to let her leave now, Batman's plan had a hiccup in the form of Robin's arrival. Batman was forced to call Robin off, allowing the assassin to flee. Giving a sample of his own blood to Robin, Batman instructed him to find any hospital that carried the same infected blood, and help out however he can.

Batman found another victim of the Identity Thief nearby, finding a scalpel left at the crime scene. He asked Oracle to find a match from the prints on it; to his shock, the prints matched his. Oracle told him that he might be the Identity Thief, due to Strange, Crane or another psycho's manipulation. However, Batman was adamant that he wasn't the killer; Oracle agreed, but told him to keep a look out. Hearing a TYGER guard telling Strange over the radio that the Medical Center is devoid of life, Batman went to investigate. He found the Riddler's questions marks all over the church and went inside; he met with a projection of the Riddler, who challenged him to solve his riddles to save the hostages.

Learning the first hostage was in the courthouse, Batman took out the thug undercover in Two-Face's gang and the loyal members tricked into watching the hostage. The hostage gave Batman a radio code, which Riddler gave a riddle on; solving these lead Batman to more hostages. After clearing five rooms, Batman learned Riddler didn't think he would survive the fifth one and still had more hostages. Oracle told Batman that all the rooms Batman visited were bought from Mr. Fine and that the only other property sold by him was under the arch by the Iceberg Lounge. Inside, Batman found the remaining hostages being forced to walk with explosives on their heads. Batman took down Riddler and left a dummy explosive helmet on him with Cash to intimidate Riddler into walking as payback.

Batman returned outside, and began tracing the signal. Reaching the end of Park Row, Batman found another victim of Deadshot, tracing the shot back to the top of the Gotham casino, where a tripod had been left behind by accident; Deadshot was getting sloppy. Batman scanned it and learned it had traces of a rare metal used in paints a decade ago. He also told Oracle to use what he knows about the victims to find out why Deashot was targeting them; so far the only thing he knows if that they worked to build Arkham City.

Following the signal again, Batman learned from the chatter between Joker's men that the assassin had gone down the hole to the sewers in the Industrial District. Once underground, Batman learned that Joker's men were chasing after the men still loyal to Penguin; either they would switch teams and work for Joker, or they would be killed. Taking out the men, Batman found the signal leading him back into the train station; numerous men were already dead, likely at the hands of Killer Croc, who lived in the sewers.

Batman followed the signal into a disused area of the original Gotham. He found some of Joker's men talking about the old Gotham that was built over, creating the current "Old Gotham"; he took them out and found more at the base of Wonder Tower. They were holding an intern doctor hostage, and taking TYGER weapons from storage. Batman saved her, learning that Strange is kidnapping ANY doctor he can get his hands on, in an attempt to heal the Joker. However, a phone call from Joker revealed that Strange actually GAVE the weapons to Joker; possibly to control the gang war.

Finding the closed off area of Wonder City, Batman followed the path; to his horror, he found not only where there bodies strung up like pinatas, but his health was starting to go down hill. All the while, a familiar prerecorded voice talked about Wonder City. Using his Detective Mode, Batman found the Mechanical guardians possessed a relatively old video system, something too advanced for a device created in the 1800s; using it, Batman found how the assassins where getting further into the city when the main door had remained shut for centuries. There was a secret path, which could be opened by a blade akin to a keyhole. Batman knocked out an assassin and used her blade to open the path.

Having more attacks from the poisoned blood, Batman saw a vision of his parents welcoming him to the next life. However, Oracle snapped him out of it and get Ra's blood for the cure; she told him that he had mere minutes left, since all the fighting pumped the poisoned blood through his body faster. Confronted by the assassins again, Batman was saved by Talia. Talia slapped him, and he greeted her.

When Talia asks how he found the League's hideout, Batman explained that he recognized her guard, and that it was only a matter of putting a tracer on her to find them. Talia dismissed the assassin Batman tracked, telling him that he didn't need to get captured; he could have just called her. She proceeded to unmask and kiss him, but was shocked by his face appearing so terrible.

After explaining he needed to see Ra's, Batman was told that only a true successor to the Head of the Demon can be in his presence. Annoyed, Batman used his terminal condition as an excuse to take the Demon Trials needed to be a true successor. Batman drank the blood of the Demon, gaining back a few more hours of life, and joined Ra's astral projection in a spirit world modeled after Arkham City. Batman flew through the spirit world, fighting apparitions of assassins and was deemed worthy enough by Ra's to take his place; it was now time for them to meet in the real world, for the final test to become the next Head of the Demon.

Reunited with a surprised Talia, Batman was lead into a chamber housing the Lazarus Pit; next to it was a barely alive, zombie-like Ra's al Ghul. The Head of the Demon declared the final test was to kill him and take his place. Batman revealed that his willingness to join was a ruse to get a blood sample from Ra's; unfazed, Ra's offered to be impaled by his own sword to let Batman take his blood. When Batman refused, Ra's fell into the pit as electricity boosted its strength; Ra's emerged fully restored. They proceeded to fight, with Ra's inducing an illusionary landscape to confuse Batman and force him to take his life in desperation; however, Batman prevailed without killing Ra's.

Defeated, Ra's was tended to by Talia; however, he soon held a knife to her throat, threatening Batman into killing him and taking his place. If Batman refused to comply, he would kill the only person Batman ever loved. Using a Reverse Batarang, Batman knocked Ra's out; he proceeded to take a blood sample from Ra's. Talia was furious with both of them, deeming her father insane for threatening his own flesh and blood; she was also angry with Batman, as she believed that she love between them had finally brought him into the League.

As Talia left, Batman noticed that Ra's was looking older than usual. Ra's admitted that he had used the Lazarus Pit too many times for it to have a lasting effect on him anymore; his body and mind had been pushed to their limits. Batman advised Ra's to stop his crusade and use of the pit; if it fell into the wrong hands, centuries of destruction would ensue. Batman radioed Oracle, explaining that the Lazarus chemical and how it may had some good use in future research. However, if does have some nasty side-effects.

Returning to the subway, he also found Joker's men had slaughtered faithful members of Penguin's crew, while recruiting those willing to follow the Clown Prince of Crime; on the surface, Two-Face's gang had done the same. To his surprise, Batman heard Strange announce that the failed warden of old Arkham and mayor of Gotham, Quincy Sharp was being sent into Arkham City. Wondering "how the hell did Strange manage to get the mayor arrested", Batman saved Sharp and interrogated him, learning that Strange was the one who orchestrated the entire Arkham City system, and was working with someone. Despite his desire to investigate, Batman was advised to return to GCPD by Oracle.

Finding the stranger on the next rooftop, Batman was left another symbol to scan. Batman headed back to the GCPD, but found a third victim of the Identity Thief in the alley next to Ace Chemicals. Finding bleach was used to clean up the mess, Batman traced it to a criminal washing his hands nearby. The criminal told him that "Bruce Wayne" told him to dump the body and had a hideout near the courthouse. Batman took this lead, finding a twisted room filled with operating equipment and diagrams of his own face. Turning on a tape, Batman learned that Dr. Thomas Elliot was behind the murders; at that point, the man in question arrived and showed off his face, which was a copy of Bruce Wayne's patched together from all his victims. Thomas told Batman that he wanted revenge, and that he was letting him go because he felt merciful. Once the deranged doctor left, Batman contacted Oracle and updated her on the events of the Identity Theft case.

Batman recieved a call from Joker, who had grown impatient and paranoid about his progress; Joker had convinced himself that Batman planned on double-crossing him, and put up snipers in the Amusement Mile to keep Batman out of the GCPD. Luckily, Batman managed to get past them and the goons trying to get in by using the REC to open the gates. Inside, Batman gave Freeze the vial of blood, which the scientist put in a machine with the cure; it mixed them both, leaving two vials. Freeze locked one in the safe, while holding onto one; he noticed Batman was becoming increasingly unwell.

Batman asked for his dose, only to learn that Freeze plans on leveraging it to make the Dark Knight look for Mrs. Fries, who was taken hostage by the Joker. Batman refused and Freeze broke the vial. A fight ensued between the two, with Batman rendering Freeze senseless. Both then discovered that Harley Quinn store the cure during the fight. Batman left, not only to find the cure, but to save Nora. Unfortunately, Joker derailed his plans by shooting down Vicky Vale's helicopter into Arkham. Taking out snipers, Batman saved Vicky, and got a call from Joker, who laughed at him. Batman denied an interview before taking off after Joker.

Once more finding the stranger near by, Batman was told that the moment for answers was soon. The stranger left a symbol again. Batman discovered that they made a master sigil over Arkham City and that a fifth symbol would appear at the church. Once Batman found the fifth symbol, the stranger appeared and introduced himself as Azrael, a loyal servant to the Order of St. Dumas. He told Batman a prophecy; though Batman will save the day, this will spark events that will burn Gotham and himself. Telling Azrael that he doesn't believe in fairy tales, Batman was told that the message had been delivered and that the two of them would meet again.

Batman was contacted by Alfred who informed him that Lucius had manufactured and delivered a cure on a rooftop; he injected himself with it, falling unconscious. Batman awoke to find that the Mad Hatter was the one who contacted him, having placed the idea in his head back when he rescued Vicky. With a specially-made mask placed on his own, Batman fought of the Mad Hatter's control; he broke free, knocking out Tetch and his mind-controlled goons.

Back outside, Batman found a third victim of Deadshot, tracing the shot back to where it was fired. Scanning Deadshot's last location, Batman found more traces of the unique paint, deciding that substations were the best bet for finding him. This lead him back to the Amusement Mile (as all Deashot's sniping locations came from near the area), near Poison Ivy's lair; the substation held a PDA with Deashot's hit list. This lead Batman to Jack Ryder, Deadshot's next target. After saving him, Batman snuck up on Deashot and knocked him out, taking his weapons. After locking him in a compartment, Batman told Oracle to let Gordon know where he was.

At that point, Batman was contacted by the undercover cops in the Iceberg Lounge. Officer Jones gave Batman an upgrade for his Disruptor, allowing him to remotely detonate bombs blocking his path. With this new upgrade, Batman proceeded to the Steel Mill, finding Joker's thugs keeping Warehouse 5B locked up. Breaking in, Batman knocked out the thugs trying to defrost Nora to rape her. Once Nora was safe, Batman returned to the GCPD, where he let Victor know where Nora was.

Despite Joker increasing his security, which included snipers and guards that used ultraviolet goggles to detect him, Batman was able to break into the Steel Mill. Oracle radioed him, telling Batman that Strange had gotten the permission of the city council to activate Emegency Protocol 10; he had provided weapons to the Arkham City inmates to force Gotham to allow him to mass murder the criminal element of the city, therefore cleansing it of crime for good.

As he made his way through the Steel Mill, Batman saw a healthy Joker announce that he planned to break out of Arkham City in a kamikaze attack. Fearing for Gotham, Batman proceeded further, finding a Two-Face goon being tortured for information; Batman knocked out his torturers and then the victim to keep him quiet. Heading further into the mill, Batman as attacked by Dr. Baker by accident. She told him about Proximity Bombs in the next room before going back into hiding with a steel pipe as protection.

Batman came face to face with Harley, who had been tied up; she revealed that Joker had stolen some of Freeze's equipment and locked it down in the Boiler Room. Down in the basement, goons were firing at ceramic Penguins; Batman beat them up and found a box containing a Freeze Blast upgrade.

Batman headed to Joker's room, which lead him to a fun house; Batman saw Joker was still looking terrible in the mirror. However, when Joker turned around, he was revealed to have been cured; they fought, with Joker calling in Mr. Hammer and a TITAN to odd the evens.

After his fight with Joker, the ceiling gave way due to missile attacks from Protocol 10; Batman was pinned, unable to degend himself. Joker was about to kill him, when Talia appeared and offered him immortality in exchange for Batman's life. When Batman advised her not to do this, Joker knew it had to be the truth and took the deal and let Batman live, and left with Talia who had reactivated the tracking chip that Batman had previously placed on one of her ninjas earlier.

Batman awoke to find Catwoman getting debris off him; they exchanged banter, with Catwoman going off to hide. Leaving through the hole in the fun house, Batman radioed Alfred, explaining Protocol 10 was the killing the inmates by missile strikes via the helicopters. Attempting to find Tailia, he ordered Oracle to reroute the WayneTech satellites. However, both Oracle and Alfred told him that he cannot allow Strange to win and kill all these people, guilty and innocent alike. Convinced that he needed to save Gotham before saving Talia, Batman ordered Oracle not to lose the tracer's signal as Talia didn't know what Joker was capable of; Ms. al Ghul was out of her depth on this one.

Batman went to find the chopper holding the Master Control Program for Wonder Tower; once done,Batman downloaded it and broke into Wonder Tower. Finding Political Prisoner being held hostage, Batman knocked out the TYGER guards present. Strange contacted him via the monitors, threatening to kill another Political Prisoner to get Batman to listen to him. The professor was convinced that Batman was the cause of all the insanity in Gotham, calling him the catalyst that allowed the virus that was Gotham's crime to evolve and produce the super criminals that have fought Batman over the years. Batman fought his way through the TYGER Guards, traversing Wonder Tower, until reaching the observation deck that Strange worked out of.

Overhearing Strange's gloats, Batman learned that the professor planned to wipe out the criminals in Metropolis and Keystone using the Arkham City program. Batman took out the guards, and broke into Strange's room. Strange declared himself to be the rightful successor to Batman, but Batman knocked him out with a head-smash to the glass. Plugging a remote device into Strange's computer, Batman ordered Oracle to shut down Protocol 10. Angered, Strange tells Batman that he ruined everything; Batman shoved Strange to the window, showing the mad professor the smoldering remains of Arkham City.

Undeterred by this, Strange gloated that soon he would command forces beyond Batman's comprehension and that the world forever thank him. However, at that moment, a sword was plunged into Strange; it was Ra's al Ghul, who declared that Strange's part in the plan was over. Batman tended to Strange, who begged Ra's for more time; Ra's revealed that Strange had been working for him, after coming to him with Batman's true identity. Ra's gave Strange unlimited resources for his plan to create Arkham, but Batman has proven to be the more worthy successor to the Head of the Demon.

With his dying breath, Strange activates Protocol 11, detonating the observation deck. Batman tackles Ra's out of the window before the resulting explosion, trying to save him from becoming a sidewalk pancake; however, Ra's ran his sword through his own chest as a last-ditch attempt to kill Batman. Forced to let go, Batman landed in the Bowery, while Ra's body landed on the gate of Arkham City.

To Batman's surprise, Joker appeared on the television in front of the gate, telling him that he and Talia were at the Monarch Theatre. After taking down the patrols guarding the entry, specifically snipers armed with weapons capable of penetrating the Batsuit, Batman infiltrated the theater. After a brief stand down, Batman learned that Talia had intercepted the cure from Harley, and had also seemingly killed Joker in the process by stabbing him with her sword. However, Batman then deduced from the various things that he had heard that the Joker he had seen was actually a double and attempted to warn Talia, but she ended up shot by the real Joker.

The stabbed "Joker" was revealed to be Clayface, who quickly attacked Batman. Batman managed to throw Freeze Blasts at Clayface, grabbed Talia's sword from his melted body, and sliced him into pieces. Joker triggered bombs on the floors as Batman to fell down into the Lazarus Pit Chamber along with Clayface and fought him and his mini versions of him. With Clayface defeated, Batman took half of the cure. Seeing Joker about to jump in the Lazarus PIt to heal himself, Batman used the sword to knock some machinery down and knock Clayface in instead. Because Clayface wasn't human, the resulting mixture of chemicals caused an explosion that destroyed the pit.

Joker begged for the cure, going on to say that Batman will give it to him; he poisoned Gotham and killed Talia before breakfast, but knows Batman will still save him. Batman struggled with the decision to give the Joker the cure, as Joker always broke out and killed no matter what he tried to do; Joker told him to think of it as a running gag, stabbing him in the arm. Batman dropped the vial, which broke and released the cure on the floor. Joker tried frantically to ingest the cure, but failed. Seeing that death was coming, the Joker asked if Batman was happy now that Gotham would be free of the fear his mayhem caused.

Instead, Batman looked somberly down on the dying clown and told him something surprising: the Joker was right! Even after all the chaos and deaths that the Clown Prince of Crime caused, Batman would have given him the cure if he had just asked for it over trying to steal it. The Joker found the fact he actually managed to win a battle with Batman hilarious, dying with a smile.

Batman carried the Joker's corpse out of the theater, much to the surprise of the thugs, who thought Joker would have succeeded in becoming immortal. Harley saw this, becoming heartbroken. Batman continued onwards, right out of Arkham, where Gordon and the cops were waiting. Laying Joker on Gordon's car, Batman left without so much as a word.

### After Arkham City Incident

After Batman left Arkham City, he contacted Alfred to tell him that his work there was done and that Arkham City was shut down, but was struck by bolts of electricity and confronted by the second Electrocutioner, who wanted payback on Batman for stealing the Shock Gloves from Lester Buchinsky's (his old boss) corpse on the rooftop. Batman had managed to freeze his face with the Freeze Grenade and knocked him out while he was frozen. When Batman left him for the GCPD, the Electrocutioner was confronted by the Arkham Knight, who then executed him with a shotgun. The day after, Batman discussed with Alfred the risk of endangering his lives, which was becoming more common, as well as his duties as Bruce Wayne.

### Harley Quinn's Revenge Incident

Twelve days after Joker's death, a grieving Harley Quinn took back control of the Industrial District with her old gang, and kidnapped three GCPD officers. The area was now filled with banners honoring the Joker's memory. Batman was called in by Gordon, who noted Harley blamed him for Joker's death; this entire situation was part of some revenge scheme. GCPD was unable to do anything more than keep the criminals in the area with helicopter patrols; Batman was the only one who could get inside without detection.

Batman headed to the Loading Bay Office inside the Steel Mill and saw a police officer that was held captive by a group of Harley's Thugs, who were planning on beating the officer like a pinata to let off some stress. Batman quickly defeated the gang and rescued the officer who then revealed that the other remaining officers were being held hostage deep within the other sections of the Steel Mill. Batman continued his search for the remaining officers by using a blood trail that he had found at the gate entrance of Steel Mill which lead him to a secret TYGER entrance guarded by thugs. After interrogating one, Batman went after the three henchmen Harley trusted with the key cards; he managed to open the entrance to find a threat directed towards him, left by Harley, who knew he would manage to get into her hideout.

 After he entered the Shipyard, Batman found the second cop and took out the thugs that were guarding him. Harley arrived and tried shooting the cop, but Batman took the bullet to the chest; though his armor protected him, Batman was knocked out by the force of the shot. The thugs removed his utility belt, which immediately activated the anti-theft shock; this kept in on the floor, where the thugs left it alone. Harley then had Batman sealed inside an airtight, glass ball that was in a gigantic Joker Robot. Upon waking, Batman noticed his belt was missing and decided to enter a meditative state to lessen the amount of air his body required.

Two days later, Robin arrived and stole Harley's key codes to the ball and freed Batman. Harley revealed that there were three bombs that were stolen from the GCPD Lockup that were placed around the Shipyard for the Dark Knight to detonate, before she unveiled her final plot of revenge by activating the Wonder City Mechanical Guardians and pitted them against him. After he had destroyed them all, Batman took Quinn out, but not before she had revealed that she had intended on blowing up the entire Shipyard with Robin, Batman, and herself still inside. However, Batman escaped with Harley, who attempted to stab him from behind, but was knocked out cold by Robin. Batman then quickly left Arkham City.

## Trivia

* Batman was voiced by Kevin Conroy. Conroy had previously voiced the character in *Batman: The Animated Series*and other DCAU related shows, as well as in previous games and animated movies. He was voiced, however, by Roger Craig Smith in *Arkham Origins* in a similar style to Conroy.
* Bruce presumably suffered from a form of PTSD, as he frequently saw hallucinations of his parents being killed when under heavy stress, and whenever the situation was similar, as seen in a crime scene investigation in *Origins*. In addition, in *Knight*, he started seeing hallucinations of Jason Todd simply because the event of Robin going after Joker Infected reminded him of Jason's demise in the hands of Joker.
* In the Arkham Origins GCPD Files, the GCPD knew little about THE BATMAN, but he was wanted for questioning. Criminal elements were beginning to realize he was a real threat to them, though there was still widespread skepticism that regarded his existence. Conflicting reports suggested that he was one man, many men, or a creature. Limited forensics, photos or videos suggested that he was not real, just reports from eye witnesses.
* Before the events of Arkham Origins, Batman was working in the shadows by shutting down the Carmine Falcone illegal drug operations.
* Batman had been poisoned in all four games. In *Asylum*, he was repeatedly gassed by Scarecrow. In *City*, the Joker injected him with his toxic blood, and in *Origins*, Copperhead poisoned him with her claws, and he was poisoned by Scarecrow again in *Knight*
* He left Wayne Enterprises to Lucius Fox.
* To illustrate his youth and inexperience, Batman's suit in Origins had heavier armor, that was designed to appear assembled rather than manufactured. He later switched to the more flexible and lightweight suit that was seen in *Arkham Asylum* and *Arkham City* that still provided bullet protection. His final Batsuit was even lighter and not only allowed Batman to move at his full speed with full range of motion finally while providing great protection from bullets and impacts with liquid armor it also provided many other functions, such as allowing him to survive extreme G Forces, lessen and absorb the blows of impacts and able to redirect that absorbed power back to his opponents, and also compressed around wounds if his suit was actually punctured. As Batman got more experienced his suits became lighter and offered less and less protection; favoring speed, mobility and while relying on his own experience and skill while offering great protection to impacts and moderate protection from bullets although is vital organs were still heavily armored. His later suits and gadgets showed a rapid shift to high technology to assist him in the field by enabling him to do things he normally couldn't do as well as monitoring his vital signs among many other things. His earlier suits and gadgets while were low to non existent tech offered amazing protection to impacts and bullets to his entire body but slowed him down considerably.
* Despite officially standing at 6'2, Batman appeared taller, standing around roughly the same height as Deathstroke in *Arkham Origins,* despite the latter standing at 6'5. He was even described in 6'4 by the GCPD reports. This may be a case of his armor adding additional height, a rough estimate by the GCPD or simply a scale error.
* In *Arkham Knight*, Batman started with his *Arkham City* suit and then changed to the new one, which made him more agile, flexible, bullet-proof, and faster at gliding and combat.
* The picture of Batman on the wanted poster in *Arkham Origins* was taken from *Arkham City*.
* Batman's reputation grew as the series progressed. In *Origins*, he was largely regarded as a **myth**. Some criminals didn't believe that he had existed, and was a story that the GCPD had made up to intimidate them. In *Asylum*, he was considered a **hero** and beloved by most of Gotham, though some people still thought that he was a myth. In *City*, he was known to everyone as a **hero and protector**. In *Knight*, he is known as a **savior and champion**, albeit with controversy regarding Joker's death.
* Batman's most common title aside from his name in the *Arkham* series was The Bat or Bats. Another title, "Dark Knight", was the most commonly used, usually by the Riddler and Hugo Strange, and once by Joker at the end of *Arkham Asylum*.
* Six villains and one anti-heroine overall knew Batman's identity. In *Origins*, Bane had managed to figure out who he was, though he couldn't remember it after his TN-1 overdose. In *Asylum*, a hallucination of Scarecrow was aware of who Batman was and the real one implied who he was in *Arkham Knight*. In *City*, Talia and Professor Hugo Strange both know his identity, although it was implied that Bruce had revealed his identity to Talia rather than her deducing who it was, who may have revealed it to her father, Ra's al Ghul. The Arkham Knight was aware of the Dark Knight's identity. Catwoman mentioned his name after they defeated the Riddler, which indicated that Batman had revealed his identity to her some time between *Arkham City* and *Arkham Knight*. At the end of *Arkham Knight*, Batman willingly revealed his identity to the world to stop Scarecrow and saved Gotham. Even though everyone knew his identity, most criminals and the GCPD still called and considered him Batman, and did not actually care who was under the cowl like Deathstroke. A few people were in disbelief of who he was and did not actually believe that he was Bruce Wayne (namely The Riddler, Hush, and a few GCPD Officers). Some criminals, however, were no longer scared of him now that they knew Batman was just a man under the suit, and many actually threatened to sue him for the legal damages that he had caused over the years and many had vowed to attack Wayne Manor after they were released. Because of that, Batman activated The Knightfall Protocol, and appeared to die in the explosion at Wayne Manor, although many believed that this was just Batman who faked his death and Alfred's as well.
* Batman had attracted the attention of two secret societies: The League of Assassins and the Order of St. Dumas.
* Fans believed that the title "Arkham Knight" was referring to Batman before learning that it was the title of the game's second main antagonist.
* Batman was referred to as predictable several times. Joker noted it in *Asylum*, Strange stated his identity and moral code made him predictable, and the Arkham Knight mocks him by stating that criminals now know his move before he does by putting innocents in danger, or as the Arkham Knight calls them "the weak and the helpless". The Knight states it's what he likes about Batman as his code is the reason criminality will win in their final battle with him. Despite being predictable in action Batman has always prevailed and defeats common criminals, Super-Villains, World class Assassins and an entire army.
* Bruce Wayne's birthday was on February 19, coincidentally the same day with David Mazouz, the actor who portrays a young Bruce Wayne in *Gotham* TV Series.
* In *Arkham Knight*, when Batman had to destroy the Cloudburst Tank, upon hitting the tank and then fleeing, it was possible if one listened carefully, one could hear Batman slightly chuckling.
* Jason Todd was the only member of the Bat Family that Batman did not say "goodbye" to in Arkham Knight. However given the circumstances, he never had the opportunity to do so.
* It was heavily implied that Batman became the bat monster at the end of *Arkham Knight*. If the Penguin was captured after Batman's identity was revealed, Penguin stated that Batman just needed to don a new identity, and mocked him by asking if it would be that of a squirrel. Batman responded with: "You'll see".
* Batman was being stalked by two different people during the events of Arkham Asylum and Arkham City. One stalker was Azrael, who had been studying Batman for years as stated in Knight, and the other one was Jason Todd. Azrael had followed him during both the Asylum and City incidents, and Jason was still imprisoned during Asylum and followed Batman during City.
* Batman's immune system is likely greater than an average person's by the time of *Arkham Knight*, having two toxins in his body which he managed to partially cure to prevent death - Copperhead's poison and the Joker's TITAN-tainted blood. He has also been repeatedly exposed to Fear Toxin, building resistance to stronger batches. Batman also likely has some lingering Lazarus in his immune system.
* In Arkham Knight, upon closer inspection on Batman's ionic black and grey skin utility belt, the League of Assasains logo could be seen, and referenced Bruce and Talia's relationship from Arkham City. This is somewhat odd, as the costume is based on Dick Grayson's batsuit from the comics, not Bruce Wayne's.
