"I am vengeance! I am the night! I am Batman!"

—Batman to Joker

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. But 5 years later, Batman was revealed to be alive.

Incident Reports

Before Arkham Origins Incident

When he was 8 years old, Bruce watched helplessly as his parents were gunned down in front of him. The first person to talk to him after the tragedy was a kind police officer named James Gordon. He offered the boy what little comfort he could. The family's faithful butler, Alfred, became Bruce's legal guardian and tried to help. Bruce forever had his childhood stolen from him. Bruce became obsessed with avenging his parents' murder and created a plan for the rest of his life.

For the next several years from his childhood to young adult life, Bruce trained extremely extensively to the height of mental and physical perfection. He studied various detective techniques, criminal psychology, invention, computers, disguise, escape arts, tracking, acrobatics, weapons, and marksmanship to name a few.

Bruce went on a journey to learn and master the many highly refined forms of Asian martial arts and eventually traveled to North Korea. There, Bruce discovered a secret Korean monastery where he met martial arts master, Kirigi of the League of Assassins. At first nothing more than servant and a foreigner, Bruce was eventually allowed to train with his students in Tokagure-Ryu and other Shinobi arts similar to the Japanese Ninjutsu. Mastering all of them, and even managing to defeat Kirigi's best student Shiva, Bruce earned the sensei's respect and was allowed access to the knowledge that he had been seeking as well as more advanced training.

Returning to Gotham after several years abroad, ostensibly to reclaim his inheritance and become the CEO of his family's company, Bruce realized that he needed to become a symbol to fully utilize everything he'd learned on his journey. He chose the image of a bat, an old childhood fear, and began crafting an identity to prey on both of the superstitions and the cowardice of criminals. He confided this plan to Alfred, who did not initially approve but faithfully stood by his charge and helped him renovate the caves beneath Wayne Manor into a base of operations: the Batcave. Bruce befriended Lucius Fox, though he didn't share his plans with him at first, and used his position to develop or "borrow" custom-made items that could be useful in his crusade. He assembled his first armored Batsuit and Utility Belt out of various materials from the Batcave and Wayne Enterprises, and re-purposed a prototype stealth jet to act as the "Batwing", a means of transport and an aerial delivery system, with plans to develop the future Batmobile. He also undertook an investigation into a brutal serial killing incident around the time of Halloween of his first year, which Alfred later referred to as "a long one".

For over two years, Batman waged a covert war on Gotham crime, and focused on everything from typical muggings and robberies to powerful figures such as Carmine Falcone, his rival Sal Maroni, and up-and-coming crime lords, Black Mask and the Penguin. He also solved several cases beyond the police's capability to handle, such as the holiday themed killer named Calendar Man and a crime wave perpetuated by the mysterious Red Hood, which Batman suspected of being a cover identity assumed by more than one person. His first and only confrontation with the Red Hood ended in disaster during a break-in at the Ace Chemicals Plant. The villain fell into a vat of chemicals, either by accident or on purpose to escape justice, which marked the first failure in the young vigilante's career. The Red Hood's body was never found.

Batman continued his war, gained more confidence with each victory and continued to develop his arsenal. Most criminals believed him to either be an urban legend or some kind of supernatural entity, both of which gave him a psychological edge to exploit as they began to realize that someone or something out there was an active threat to their stranglehold on Gotham. Batman avoided media attention for as long as possible, and added to the power of his chosen symbol. As a new year drew closer, Batman believed himself to be the only thing that stood between the innocent and the predatory, and that he could handle any opponent.

This would be challenged soon.

Arkham Origins Incident

Batman investigated at Dixon Docks where thugs hid there and ambushed them. He investigated a box that belonged to Queen Industries and discovered that the box had a bomb in it. After barely escaping the blast, Batman was confronted by Deathstroke, who was hoping to collect the bounty on Batman's head. During their fight, Deadshot interrupted Deathstroke's chance to kill Batman when he destroyed Deathstroke's Sword with two well placed shots. Deadshot then shot the chain that held a shipping crate, and allowed Batman to escape. Batman discovered the bullet fired from Deadshot, and noticed that the bottom said AmerTek, the name of the company who manufactured the bullet.

"Whoever kills you tonight is going be famous AND rich!"

—Batman learns Killer Croc won't be his only problem.

Christmas Eve in Gotham began with a bang when Black Mask led a sudden and seemingly random all out attack on Blackgate Prison, and took Police Commissioner Gillian B. Loeb, hostage. Batman responded immediately. His first act upon entering the facility was to rescue Warden Martin Joseph from being beaten by one of Black Mask's Henchmen. After following a trail of destruction and subduing several of Black Mask's thugs and the escaping inmates, Batman noticed that a drone was tracking Black Mask through the prison. He finally caught up to Black Mask in the Death Row Execution Chamber, but was too late to prevent the mobster from releasing Calendar Man and executing Loeb in his place. Batman stopped pursuing Black Mask and his escort to retrieve the damaged drone's memory card before he headed to the roof. Black Mask escaped via helicopter while Batman confronted the first of eight hired assassins: Killer Croc. After defeating Croc, Batman interrogated him for information about Black Mask's whereabouts to no avail, and left him for the GCPD.

"Punk in the Santa Hat must be in charge."

Batman returned to the Batcave, scanned the damaged drone's memory card on the Batcomputer, and learned that some of the world's deadliest assassins had come to Gotham to claim a $50 million bounty that Black Mask had placed on his head.[70] He headed into the city to track down the drone's operator, Oswald Cobblepot: the Penguin. As the Batwing neared the city, Batman noticed a jamming signal interfering with the plane's systems and entered the Coventry GCR Tower to investigate further. Finding it under siege by armed thugs, Batman rescued the hostages and investigated the murder of a Gotham Optics employee named David Shannon, who had been killed by an explosive placed in an access panel. Further scanning indicated that it had been placed there by a criminal named John F. Baker who had mysteriously turned up dead later in the Diamond District.

Batman shut down the jamming signal and was contacted by Enigma, a mysterious hacker who had jammed the Batwing's signal in all the GCR towers in Gotham. Batman tracked the signal to Enigma's hideout, but was met with a television conversation with Enigma instead; Batman learned of relays protecting Enigma's main server and of datapacks held by his hired help that would be used to blackmail powerful people in Gotham.

"The Penguin. Not one dime in Gotham gets exchanged without him involved somehow. If anyone knows where Black Mask and his assassins are, it'll be him."

—Batman investigates Penguin

Batman then made his way to Jezebel Plaza to interrogate Penguin's arms dealer, Ricky "Loose Lips" Leblanc and observed him and the Penguin's Henchmen selling weapons until he interrupted their deal. The vigilante attempted to interrogate the terrified Leblanc, only to unintentionally choke him into unconsciousness. Not long after, Batman started to interrogate him on the roof of the Gotham Merchant's Bank before Cobblepot texted Loose Lips to check the progress of the deal. Batman took the phone's memory card to hack into Penguin's communications, and dropped the now unnecessary Loose Lips off the roof and straight into the plaza's Christmas Tree.

However, he soon found that he needed to triangulate the signal by using the relay stations Penguin used for his private radio. Once this was done, he overheard Penguin talk about the Boiler Deck Fights, which were being held on his ship, The Final Offer. Batman believed that Cobblepot would give up a lead on Black Mask's location. There, Batman faced the would-be assassin, the Electrocutioner, and knocked the loud mouth out with a kick to the face. After Batman went after Penguin's assistant, Tracey Buxton, he received a message about Electrocutioner, who left the arena and claimed that he would be back for him. Batman found Tracey in the casino and locked her in a cell before he unlocked the security locks barring his progress.

"I'm not playing games, Slade."

Batman interrupted the Penguin's torturing of his rival's son, Alberto Falcone. He learned from Penguin that Black Mask had "problems of his own" that was related to a murder that was committed at his Lacey Towers safe house before he was interrupted by another assassin, the far more capable Deathstroke. Batman managed to defeat Deathstroke and purloined his Remote Claw. Batman contacted Alfred to arrange an anonymous tip about Deathstroke's whereabouts to the GCPD before his manservant informed him of police band chatter that indicated the Lacey Towers murder victim may have been Black Mask himself.

"I've planted three bombs where Gotham's corruption is at its strongest. But unlike those I fight to overthrow, I believe in choice. So I offer you one: Let them detonate or stop them. Your actions will determine what I do with you."

—Anarky's challenge to Batman

After he left the Final Offer, Batman discovered a transmission from Anarky, who threatened to bomb "corrupt" institutions all over Gotham and challenged the vigilante to deactivate them. Batman found bombs at the bank, casino, and GCPD; he disabled them and received a call from Anarky. The radical was not angry, but instead intrigued by the idea of Batman's crusade; he told him where to find him - the Solomon Wayne Courthouse. Anarky proposed a team-up to eliminate the corruption in Gotham, but Batman refused. Anarky and his followers attempted to defeat him, but Batman won. He unmasked Anarky, and to his shock, learned that the radical was actually a teenager named Lonnie Machin. Anarky was left bereft at his failure and began muttering to himself about how he could have done better; he considered becoming an ally/apprentice to Batman, but decided against the idea. Batman left him to be picked up by the police

Arriving at Lacey Towers, Batman learned that the police believed that Penguin had killed Black Mask and investigated the murder scene where Black Mask and his girlfriend had been murdered several days ago. Piecing together the evidence, Batman concluded that the victim was not Black Mask and Penguin had visited the scene after the murder was committed. An unknown intruder had attacked the real murderer, and that murderer may have been a new criminal known as "The Joker".

Needing more information to solve the case, mostly a DNA analysis to confirm who the murder's assailant had been, Batman infiltrated the GCPD Building in order to access the National Criminal Database. He came across a wall of pipes, which had Captain Gordon's office on the other side. Gordon was arguing with his daughter over Batman's efforts to try bringing justice to Gotham City, but Gordon was adamant that only the police were the ones who could be responsible for that. Batman continued through the walls and next saw Gordon ordering the GCPD to be on the look out for the seven other assassins, who could possibly cause more destruction and mayhem that night in their attempts to draw out and kill the Batman.

"They're as corrupt as they come and they're in my way."

Making his way through the building, he learned that the corrupt SWAT leader Howard Branden was determined to claim the bounty and, with Loeb dead, the other corrupt officers were concerned that James Gordon would be considered for Commissioner, and they were already discussing ways to damage his reputation. Finding his way to the Server Room barred by a set of electronic locks and a jamming device, Batman sneaked into the Interrogation Room to confront Loose Lips again about a Disruptor. He learned that it could jam weapons and override security protocols.

"Wait. Why do you do what you do?

Because I made a promise."

—Batman shares some of his story

Before he could retrieve the Disruptor from the Evidence Room, Batman stumbled upon SWAT's attempt to undermine Gordon: instigating a riot in the Holding Cells by covertly releasing several inmates, including a Venom Henchmen. Batman dealt with the riot, passed the Server Room's locks with the use of his new Disruptor, and attempted to collect the information that he needed. During this he met Gordon's daughter Barbara, who gave him advice on how to establish a permanent connection. Before leaving, she asks Batman what motivates him to be a vigilante; Batman responded that it was due to a promise. At that moment, a tear gas grenade was tossed into the room; Barbara left to distract the officers that attacked, claiming to have been on the phone with a friend. Batman left via the vents, heading back to the roof. In the midst of his escape, Batman encountered Captain Gordon, who still thought the vigilante was as much of a menace as not only the criminals, but also the SWAT team that hoped to eradicate Gordon and collect Black Mask's bounty on Batman for themselves. Gordon was unfortunately knocked unconscious during the course of the fight.

With advice from Barbara, Batman entered the sewers beneath the GCPD to secure permanent access to the database. There, he found Black Mask's Gang planting explosives under several buildings, including the GCPD. This was strange since most of the force was in the crime lord's pocket. After he subdued Black Mask's thugs, Batman finally reached the terminal that would allow him to access the database and complete his investigation. The database allowed him to deduce that Black Mask was the third person on the scene, and had sent in a body double as a decoy before he attacked the murderer, only to be subdued and kidnapped by the mysterious Joker, who intended to use Sionis's bio-metric data to access the Gotham Merchant's Bank.

Batman confronted three thugs who wore rabbit masks and was contacted by Jervis Tetch, who wished to employ him to help Alice; however, this was all a lie Tetch believed as this woman was a hostage. Batman infiltrated the hat shop that served as Tech's home; he found Tetch dressed as the Mad Hatter from Alice's Adventures in Wonderland, and a group of thugs Tetch was trying to brainwash with mind-control masks. Batman took out the thugs and pinned Tetch, demanding to know where "Alice' was. However, Tetch instead hypnotized Batman into seeing Wonderland, and explained that "the Queen's forces" were trying to separate him and Alice; he decided to hire Batman as a bodyguard to ensure her safety. Batman broke free of the hypnosis and knocked out Tetch, who was holding "Alice" hostage. He then placed a call to GCPD for a trauma unit for the poor girl and squad car for Tetch's arrest.

"It's been you all along. You hired the assassins."

—Batman learns the Joker was posing as Black Mask

As midnight struck, Batman and Alfred exchanged Christmas well wishes before the Dark Knight came face-to-face with the greatest challenge of his career. Batman found the bank already broken into and full of the dead bodies of Black Mask's men. Batman caught Black Mask in the middle of escaping with the bank's money. In a stand off, the leader of the operation revealed himself to be the Joker in disguise: the Joker had replaced Black Mask days earlier, seized his criminal empire, and placed the bounty on Batman. Before Batman could stop him, the Joker escaped with a captured Black Mask and an ambulance full of cash, which left Batman to catch the strangely hysterical, Bank Manager and escape the exploding vault after the Joker blew up the vault while he departed. Batman survived, stunned by the blast, and found the Bank Manager dead with an enormous grin on her face, the first of the many victims of Joker Toxin. Batman dispatched a team of thugs sent in by Joker to find his body and interrogated the last remaining thug to learn that the Joker had killed members of Black Mask's Gang who wouldn't join him and had taken Black Mask to the Steel Mill.

Batman pursued the Joker to the Steel Mill, and intended to capture either the Joker or Sionis. Infiltrating the building, he hacked into Black Mask's computer and found that Sionis had a pacemaker installed and was having the Joker followed. In the elevator, Batman found and scanned the corpse of one of Joker's men, and discovered that he had been poisoned by a neurotoxin that caused powerful hallucinations before eventual death. Continuing toward Black Mask's Office, Batman freed then interrogated the crime boss for the Joker's whereabouts, until the venomous assassin, Copperhead, attacked and poisoned him.

Delusional and fading fast, Batman scanned traces of the poison and sent them to Alfred to hastily manufacture a cure. Batman then forced himself to stagger through a gauntlet of hallucinations that consisted of a disappointed Alfred, the Bank Manager, and Commissioner Loeb. Finally making it to the upper floor drop-off point, Batman was forced to fight, from his fevered point of view, multiple illusions of Copperhead, and kept her at bay through sheer willpower. After the container arrived, Batman cured himself, easily defeated Copperhead, and locked her in one of the shipping crates.

"I've faced murders and psychopaths, but this... this is something else."

—Batman sees an evil deeper than the typical Gotham scum

Tracking the Joker through the specific electromagnetic signal that was generated by the Electrocutioner's Shock Gloves, led Batman to the Royal Hotel. Batman found that the lunatic and his men had taken control of the building, filled it with explosives, murdered the staff, and had taken the guests hostage. To make things even more complicated, SWAT had arrived on the scene and were making sure that Gordon and the rest of the GCPD didn't know about the takeover. Joker was using the building to hold a meeting with the remaining assassins about their failure to kill Batman, and ended it by kicking the Electrocutioner out of a window to his death. The assassins all departed, except for Bane who believed that Batman would soon be coming for the Joker.

Batman recovered the Electrocutioner's Shock Gloves and used them to charge deactivated electrical equipment throughout the hotel and deliver powerful shocks to the army of Joker thugs in his way. Batman worked his way through the building, helping save what was left of the staff and was horrified by the corpses that the Joker had left defaced with numerous Christmas decorations. A concerned Alfred called him, due to the spike in Batman's biometrics. Batman told him that he was fine, but the Joker was something beyond all the crime that he's fought in Gotham.

Reaching the top floor, Batman confronted Joker, and fought Bane. Concerned that his charge was outmatched, Alfred alerted the GCPD for help, who interrupted the fight. Batman placed a tracker on Bane as he escaped by helicopter, pausing only to fire a rocket at the Joker. The concussive force sent the Joker falling from the hotel balcony. Batman dived after him and saved the Joker before he left him with the GCPD.

"When the mugger or the thief stop to think twice, that is fear. That is what I am. That is why they hired assassins - I am the reason that the criminals breathe easier when the sun rises."

—Batman to Alfred in the Batcave[src]

Returning to the Batcave, a weary Batman learned that Bane was gunned down by the GCPD and left to investigate the body at the GCPD Morgue. Alfred implored Batman to abandon his crusade, and feared that he would die, but Batman refused to listen. After he entered the GCPD Morgue, Batman discovered the body of a Venom user instead of Bane, and scanned the body to find that it was dosed with chemicals that may have caused both heart and brain damage. Batman heard over the GCPD radio that criminals were fighting over chemical weapons that were orchestrated by Bird, Bane's lieutenant. This lead Batman to the docks, where he found a matchbook from My Alibi, and headed to the night club, where Bird had taken over. Batman subdued bird and left him for the GCPD to imprison.

Batman then entered Bane's Field Headquarters, finding a recording left by the brute; Bane was aware that his addiction to Venom could kill him, so he was working on a compound that could give him a permanent increase in strength. Unfortunately, the new formula damaged the brain and left the host with severe memory loss and decreased intelligence. He then discovered computers that were full of evidence: Bane knew that Batman was Bruce Wayne. Enraged, Batman destroyed the computers and warned Alfred that Bane was most likely on his way to Wayne Manor and that he would be safer in the Batcave.

Before Batman could return home, Firefly launched an assault on the Gotham Pioneers Bridge, which forced both Batman and Captain Gordon to work together to overcome the assassin and his bombs. In the middle of defusing them, Batman saved Branden from Firefly's thugs. Branden then repaid the vigilante by attempting to attack him, only to be thwarted and left unconscious, naturally. Batman defused all but one of the bombs, but then had to battle the pyromaniac himself. Gordon ignored the vigilante's advice to let him handle the entire operation solo and prevented Firefly from detonating the last bomb. Batman defeated Firefly by damaging his jet pack and left him hanging for the police to arrest. He and Gordon then had a secret met in the aftermath, in which they both admitted they wouldn't have been able to salvage the affair without the other.

Meanwhile, Bane broke into the Batcave and beat Alfred nearly to death; Batman was contacted by Bane, who told him that Alfred could say a few last words if the Dark Knight hurried. Batman returned to find the Batcave in ruins and Alfred dying in the rubble. Alfred passed away in Batman's arms, and uttered his final request that Bruce not "add [him] to the weight that he had carried." A desperate Batman managed to resuscitate Alfred by using the Shock Gloves. As they returned to the medical bay, a call came in over the police band: the Joker had taken over Blackgate.

"They need you.

No. They need US."

—Batman assures Alfred that he won't work alone anymore.

Finally accepting that he needed allies, Batman worked with Gordon and the GCPD to retake the prison. He helped free Dr. Harleen Quinzel and some guards from the men loyal to Joker, who now ordered him to be brought in alive. Listening to the Joker over the intercom, Batman learned that the clown enjoyed their last fight and wanted to continue fighting with him as long as possible. Batman found Deathstroke still in his cell after defeating several escapees, but the mercenary had no more interest in the vigilante unless another price were to be put on his head. This was at least one less thing to worry about that night.

Finally catching up to the Joker in the Panopticon, Batman was forced to fight Bane to the death as Joker strapped himself, with a hostage Captain Gordon, to an electric chair that would automatically kill him unless a heart beat monitor attached to the chair registered Bane's death. Batman used the Shock Gloves to shock Bane into cardiac arrest. Satisfied, Joker left to detonate his bombs all around the city.

Batman fighting TN-1 Bane in the Maximum Security Ward at Blackgate Prison

Asking Gordon and Warden Joseph for help, Batman revealed that he tricked Joker; seeing that Batman didn't want to kill, Gordon agreed to help. Batman used the Shock Gloves to resuscitate Bane, which was his plan all along, but Bane was enraged because he'd been denied peace. Bane attempted to turn his Venom back on, but found Batman had tore off the control pad. Seeing that the had no other choice, Bane regretfully injected himself with the latest version of his attempt at a super-Venom: TN-1. Bane turned into a hulking beast, which Batman tried to knock out by blowing up the floor underneath them. However, both of them ended up in the cells below.

Learning from Alfred, who had been given Bane's research notes, that TN-1 would reach full effect in 10 minutes, Batman managed to force Bane into the electric barriers and knock him out. However, Bane recovered and tossed Batman into another room. Batman set a trap, handing Bane up by his foot and giving him a painful zap. As a bonus, Batman heard Bane mumble that he needed to find the Batman. Wishing him a sarcastic "good luck", Batman left to find the Joker.

Upon hearing Gordon call for a paramedic to treat Warden Joseph, Batman rushed over to find them. Finding Joseph on the ground, Batman was grabbed by the head from behind by Killer Croc; at the same time a sniper was aiming at him. Luckily, Gordon hit the sniper as soon as he took a shot; the shot instead grazed Croc's arm. The beast left Batman alone, rushing off into the chaos; he had enough of getting hurt by helping the Joker. Gordon arrived next them, helping Batman fend off inmates seeking to harm the warden. Batman was surprised to see how well Gordon could handle the inmates; the captain explained that he had a rough childhood, so he had to learn how to defend himself against thugs.

"This is why you do it, isn't it? You need it. You like the way it feels."

—In shocking turn of events, Joker may have just told Batman the very reason for his crusade against crime

Batman preparing to deliver the knockout punch to the Joker in the Prison Chapel

With the warden under Gordon's watch, Batman fought his way to the Joker in the Prison Chapel. The clown was laughing at the chaos he causes, saying that night is best he's had. When it looked like Batman would kill him, the Joker laughed that he was ready so soon after Bane; however, Batman told him that Bane was still alive. Dismayed to learn that Batman had saved Bane, the Joker tried to goad Batman into killing him, but Batman subdued him with a ferocious beatdown and let the clown live, once again. Gordon decided to let Batman go and believed that the vigilante could help the city.

Before the end of the night, Gordon contacted Batman to apprehend the 20 escaped Blackgate Prisoners that were all over Gotham. After Batman apprehended the 20 inmates, Gordon thanked Batman for his help. Batman then asked a favor: tell the GCPD to back off and let him do his job. Gordon offered to think about it and Batman told him to not take too long: he had a feeling that they would be doing this again soon.

Alfred later discovered the identity of Enigma, a Cyber Division officer of the GCPD named Edward Nashton. Nashton had also informed the Dark Knight that he would reveal the greatest secret of all soon.

Cold, Cold Heart Incident

One week later, on New Year's Eve, a week into the city's recovery, Bruce Wayne hosted the Humanitarian of the Year Awards Ceremony at Wayne Manor and fully supported the winner, GothCorp CEO, Ferris Boyle. The party was interrupted by a startling temperature drop and then a gigantic ice explosion in the Ballroom. Wayne Manor was soon under siege by Penguin's thugs, who wielded strange cryogenic weaponry and took the guests hostage. Their leader, a man in a mechanized suit that they called "Mister Freeze", marched in and demanded that Boyle be brought to him. Amid the panic, Bruce slipped away and attempted to contact Alfred with no success. He walked into an ambush set by several thugs, subdued them easily, and rescued Alfred. Bruce left Alfred to take care of the guests in the Manor's Study and entered the Wine Cellar to access another entrance to the Batcave, after he subdued several more of Penguin's thugs along the way. Donning the Batsuit, Batman returned to locate Boyle and found the Manor in flames. Returning to the Library, Batman rescued Alfred, Vicki Vale, and several other guests who had been taken hostage. After he left them in the Study, Batman had a terse conversation with Vale, who had advised him to "manage that image before someone else managed it for him." Batman rescued Boyle from more of Penguin's thugs, but was blind-sided and immobilized by Freeze. The latest of Gotham's new class of criminal expressed no interest in finishing off the vigilante and dragged Boyle away. Batman managed to break free of the ice that had trapped him, disappointed some opportunistic thugs who had thought a half-frozen vigilante would be easy pickings, and confronted the last of the invading force in the Ballroom, which included two thugs in thick padding and another who wielded a scaled-down version of Freeze's own weapon. He interrogated the last remaining thug and learned that one of Penguin's South Gotham dealers might know where Freeze was taking Boyle. Sickened that anyone would attack such a humanitarian, Batman rode the Batwing into the city and vowed to take Freeze down.

Batman found South Gotham mostly deserted but chaotic. For starters, the entrance to the Gotham Pioneers Bridge was blocked off by a wall of ice that was erected by ambitious freeze gun thugs, and Anarky's Henchmen were continuing the riots all over the city. While he tried to find Penguin's dealer, Batman found a frozen cop and learned that Penguin's thugs had used cryogenic weapons to freeze people in ice. If he was going to break them all free, Batman needed his Thermal Gloves. After he followed the trail, Batman interrogated Penguin's dealer about Freeze's location and learned that Freeze was located at GothCorp. Batman entered GothCorp to search for Freeze and learn where he was taking Boyle. Batman found Freeze, who had been betrayed by Penguin, and Boyle, who was still Freeze's hostage. Batman distracted Penguin by taking out some snipers as Freeze created a wall of ice behind him as he departed, and trapped Penguin within it. Batman learned from Penguin that the only way to break the ice, was with a cryodrill that his men had stolen and hidden at My Alibi.

Batman in his Extreme Environment Batsuit in Cold, Cold Heart

After he arrived at My Alibi, the Extreme Environment Batsuit arrived from Alfred, and Batman donned the suit. Batman then entered the nightclub to search for the cryogenic drill. He found Loose Lips in the private back room and interrogated him for the drill, but learned that the drill was in pieces. After he retrieved the cryodrill pieces, Batman needed a supercoolant that was used in a lab that was run by a Victor Fries. Batman returned to GothCorp, found Fries's abandoned lab, and learned the truth behind Fries's transformation into Mr. Freeze while he retrieved the supercoolant to use for the cryodrill. Batman returned to the Propellant Lab to break the ice with the cryodrill and left Penguin there, frozen. Batman entered the Cryogenic Testing Facility and found Freeze, Boyle, and Freeze's wife, Nora. Batman disabled the three generators that powered the cryogenic pods. After the generators were disabled,

"I can't condone your actions. But I can give you justice."

—Batman sees Mr. Freeze is the victim in this story

Batman fought Freeze. When Nora was in danger, however, Freeze went to save her, and gave Batman an opening. Batman grabbed Freeze from below and took him down. Boyle was released and activated some coolant pipes. Batman pushed Freeze out of the way and got frozen. Boyle attacked Freeze with one of the pipes, but Batman thawed out just in time to rescue him. Batman brought Boyle to justice by knocking him out and saved Freeze. Batman then saved Nora by restoring her pod and told Freeze that he couldn't give him peace, but justice. Batman then placed the supercoolant into Freeze's suit to restore it to subzero temperature.

Arkham Origins Blackgate Incident

"I thought you were supposed to be a gentleman.

I was being gentle."

—Batman defends how roughly he had to treat Catwoman in her capture

Three months later, while patrolling, Batman encountered a thief stealing something from a high-tech building. The thief, who called herself Catwoman, escaped and left Batman to deal with Department of Extra-Normal Operations Guards who were stationed in the building and on the surrounding rooftops. After a long chase, Batman took down Catwoman and left her for the police to arrest.

Two weeks later, Batman received an urgent message from Captain Gordon. Another riot had broken out at Blackgate and it was under the prisoners' control. Batman approached the prison by the river and made his way inside. After he saved Catwoman from several thugs, Batman learned that Joker, Penguin, and Black Mask had taken over three separate areas of Blackgate: the Administration Offices, the Cell Blocks, and the Industrial Area. Catwoman offered to team up and helped him navigate the prison. She also mentioned that several hostages were being held in the Arkham Wing, that Joker had cut the air supply to the area, and left them with only a few hours of oxygen.

Batman began with the Cell Blocks. He discovered that Penguin was hosting a fighting arena, which he attempted to break up. He was forced to fight Penguin's reigning champion, Bronze Tiger. Batman quickly defeated Tiger, but refused to kill him. As Penguin's thugs closed in, Tiger held them off, which gave Batman a chance to go after Penguin.

Penguin managed to escape to the Lighthouse and cut off the path. Batman returned to the Administration Offices to acquire the recently completed Line Launcher in order to proceed. He then encountered Joker, who had captured Warden Joseph and had him rigged to several bombs.

After he acquired the Line Launcher from the offices, Batman went back to the Lighthouse and continued to pursue Penguin. He was finally able to catch up to him and defeat him. Then he learned that Black Mask was attempting to overload Blackgate's power generators and cause a chain reaction that would destroy everyone and everything in the building, which included Batman and Joker, whom he blamed for his downfall three and half months earlier. While making his way to the Industrial Area, Batman encountered a large undead being in the sewers that called itself Solomon Grundy. Batman defeated the creature, confronted Black Mask, and foiled his plan.

With Black Mask taken care of, Batman returned to the Administration Building to stop the Joker and rescue the Warden. He was intercepted by Deadshot, who had made a deal with all three bosses, tripled his commission, and was eager to kill Batman for the great prize. After he defeated the assassin, Batman rescued Joseph, then proceeded to his office, and confronted the Joker. After taking down the Clown Prince of Crime, Batman acquired the set of codes that he needed to shut down the gas that was about to be released on the hostages, but noticed that the Arkham Wing's air supply hadn't been cut off at all, contrary to what Catwoman had told him.

"There were never any hostages. You were after Bane."

—Batman sees that Catwoman was just using him

Having finally defeated all three of the villains, Batman proceeded to the Arkham Wing, where he discovered that there were no hostages at all. Instead he found a weak, and skinny Bane. Catwoman revealed that she had been using Batman to get to Bane, who was the target that she was hired to recover to pay off a debt. Batman pursued Catwoman to the docks and fought her again. Before he could learn her employer's identity, a special forces team that was led by Captain Richard Flag intervened and arrested Catwoman. Though questioning the team's actions, Batman said nothing about it and flew off into the night. The Blackgate Riot was contained, though Black Mask, Penguin, and Joker had managed to escape custody in the aftermath.

Throughout the night, the riot had been secretly monitored by Amanda Waller. The breakout might have been staged by her department in an attempt to acquire Bane, who was one of several potential candidates for the Suicide Squad. While Catwoman had failed in her mission, since Captain Flag had to leave Bane behind to waylay suspicion, Waller did manage to retrieve Deadshot and Bronze Tiger. As Waller and Flag's helicopter flew off, they were unaware that one of Batman's tracers had been placed on its underbelly.

Between Arkham Origins Blackgate and A Matter of Family

Batman eventually became the target of District Attorney Harvey Dent, the White Knight of Gotham, for working outside of the law. However, with Gordon's help, he managed to convince Dent that if they worked together, crime in the city would be eradicated within a year. This worked well, with Batman apprehending criminals that the GCPD couldn't and collecting more obscure evidence for cases, Gordon as police commissioner to help fix the corrupted police department, and Dent prosecuting the thugs and unwilling to be bribed or threatened. Unfortunately, their alliance broke when Carmine Falcone was put on trial; he threw acid at Dent, terribly disfiguring the left side of his body. As a result, Dent's mind fractured and released a new second personality obsessed with duality - Two-Face. Two-Face became convinced that Batman was used him as a scapegoat for criminals to lash out at since the Dark Knight could never be found. Little did the former D.A. know, Batman regretted not being able to protect him, and felt worse when the original Harvey surfaced to speak to him.

After Arkham Asylum was reopened, Batman kept a close watch on the facility just in case another riot like the one at Blackgate every occurred again. While patrolling Arkham, Batman visited Deadman's Point - a cliff suicidal patients favored jumping off of; after saving a patient from jumping, Batman found a secret cave system that ran under the the island. Discovering that it connected to the sewers under Intensive Treatment, Batman decided to make a "home away from home"; over the years, he secretly shipped equipment to the island, building walkways and a main platform. A new bat-computer was built, allowing Batman to transfer data to the original one back at Wayne Manor. Additional equipment was left alone, ready for use if Batman needed it. To ensure the Batcave MK2 would remain secret, Batman kept its existence to himself.

Batman also maintained an ally in Barbara Gordon. GCPD attempted to prove that Batman was human and not a mythological being by creating a prototype copy of the Batsuit and gadgets; they reasoned only someone with money to spare would be able to take on the identity of the Batman. However, Gordon taken hostage by the new super-criminal Killer Moth. To Batman's surprise, Barbara stole the prototype suit and became Batgirl to save her father. Impressed, as Bruce Wayne, Batman invited the Gordons to a ball at Wayne Manor, where he allowed Barbara to hack into his private internet and thus break into the Batcave and learn about his secret identity. Batman chose to have her as his crime-fighting partner, training her extensively; they kept this hidden from Gordon, as he would not be too pleased to hear his daughter was fighting crime with a vigilante.

Attending Haley's Circus one night, Batman watched the Flying Grayson's acrobat act. Unfortunately, all but Richard "Dick" Grayson fell victim to sabotage by criminals trying to extort money from them. Feeling a kinship with Dick, Bruce adopted him and trained him as his second crime-fighting partner, Robin. They fought crime together for years, until Dick decided to go by the new moniker Nightwing as a fresh start as a new hero in Bludhaven. As fate would have it, Batman caught Jason Todd, a petty kid thief, attempting to steal the Batmobile's tires. Batman trained him as the next Robin, but found it harder to keep Jason under control as the boy's sense of justice was so strong, that he had an urge to wipe out criminals instead of reforming them.

Eventually, Jason sought to kill the Joker for all his murders and ending being captured. Batman later received a video of Joker torturing and seemingly killing Jason before he could tell who Batman was under the mask. Batman mourned for months, but was later surprised by the arrival of Tim Drake, a teenager who had figured out his true identity and that of Nightwing, as he had been in the circus crowd the night the Flying Graysons were killed. Impressed, Batman was convinced to train Tim as the third Robin, unaware that Jason was very much alive and burning with a monomaniac hatred of him for seemingly abandoning him.

As the years passed, Batman fought off an increasing amount of new super criminals. Among them were nihilist serial killer Zsasz, eco-terrorist Poison Ivy, deranged cult leader Maxie Zeus, cop-murdering Prometheus, fear-obsessed Scarecrow, split personality Ventriliquist, confused Humpty Dumpty, insane broker Great White Shark, and rat-loving Ratcatcher. Serial killers like Calendar Man and Killer Croc were among returning foes, such as the pyromaniac Firefly and the thief Catwoman. Black Mask and the Penguin also re-established their criminal empires; however, Penguin did better as he was able to pose a reformed villain that ran a legit nightclub, the Iceberg Lounge. Sionis, on the other hand, had his mask burnt into his face, rendering him unable to live a dual life; Batman was unable to send Sionis to prison, due to his army of lawyers.

Batman eventually came into confrontation with Basil Karlo, an actor who went murderously insane after learning his best film The Terror was being remade without him in the lead role. Despite arresting Karlo, Batman would face him again, along with a group called the Mud Pack that used the name of the film's villain "Clayface". Karlo stole the essence of all three of these Clayfaces, becoming the ultimate version with all their powers. The Mud Pack was arrested, never to be heard from again, but Karlo would still plague Gotham with the desire to kill Batman and take his place as it was "the role of a lifetime."

The Joker even managed to convince his therapist Dr. Harleen Quinzel that he was the victim in his battles with Batman, rather than the people he murdered for sick entertainment; to her, the Joker only wanted to bring the gift of laughter to the sad masses of Gotham. The Joker even managed to convince Harleen that they were in love, tricking her into becoming his much abused sidekick Harley Quinn. Batman felt sorry for her, often giving Quinn a chance to surrender during their fights; he usually ended up only arresting her most of the the time, as the Joker used her as a human shield or scapegoat to avoid being sent back to Arkham.

Mad Hatter continued his delusional quest to find "Alice". He was even able to form his own Wonderland gang, which consisted of Tweedledum and Tweedledee, the Carpenter, and the Walrus. Batman would often defeat Hatter and send him to Arkham with the Tweedles, as they were clearly insane. The Carpenter was a legit carpenter, often employed by the rogues to build or renovate their secret lairs.

Batman fought and imprisoned these criminals many times over the years at both Blackgate and Arkham, only for them to escape repeatedly to reek havoc upon Gotham. Using his civilian identity Bruce Wayne, Batman began shipping better equipment to Arkham to ensure the inmates couldn't escape; however, many like Joker took delight in trying to continue escaping from Arkham, which he considered a second home. Between the Mad Hatter and the Scarecrow, Batman only considered the latter a real threat, as the Hatter was too delusional to pose any more of a threat than being an annoyance; Scarecrow attempted many times to break Batman's mind with his Fear Gas, but the Dark Knight's iron will protected him from the extreme effects.

At some point, he met Amanda Waller, who he was not very pleased with; he had connected her to several other crimes with criminals under her control, which resulted in large messes he often had to clean up. Waller didn't care what was legal or morally sound, preferring to "break a lot of eggs to make an omelet."

Likely due to his past training with Kirigi, Batman was sought out by the leader of the League of Assassins - Ra's al Ghul. This mysterious man claimed to be over 600 years old, which Batman immediately believed as Ra's seemed like a man who wouldn't lie; however, how he was able to do so remained a mystery to Batman. Batman found some mutual respect for him, as they both sought to put an end to criminal activity, but was disgusted to find out Ra's wanted to eliminate crooks rather than rehabilitate them. Ra's sought to have Batman join the League as his successor and groom to his daughter Talia; though there was a mutual attraction between them, which resulting in a one-night stand in Metropolis, Batman held no desire to join the League. Batman knew Ra's died a few times over the years, but was brought back.

A Matter of Family

Commissioner Gordon was kidnapped by the Joker, and held hostage at the Seagate Amusement Park. As Joker threatened to kill Gordon if Batman appeared, the task was left to Robin and Batgirl; what Batman didn't know is this was Joker's plan all along, as he hated his sidekicks for coming between them and their endless struggle. The mission was successful, with Gordon's rescue along with the arrest of Harley Quinn and lots of Joker's goons. However, the Joker himself had managed to escape capture, abandoning his allies per usual.

Between A Matter of Family and Assault on Arkham

The Joker soon after surprised Barbara Gordon at home, shooting her through the spine and leaving her paralyzed from the waist down; he did this to emotionally torture commissioner Gordon. Little did the Joker know, is that this also affected Batman, who blamed himself just like Gordon did. However, Barbara chose not to let her new disability keep her from helping fight crime. Taking on the new identity of Oracle, she now served as Batman's primary source of information gathering thanks to her hacking skills, remaining in radio contact with him while he's in the field, effectively leaving Alfred free to attend other matters for Batman.

Still feeling some guilt, Batman set up Barbara in an apartment in the Bleake Island clock tower, which doubled as her base of operations. There were numerous servers installed to help process data faster for crime scene analysis, linked to the Batcave's own computer. There was also a secret hatch installed on the roof, which could be remotely opened to allow Batman and/or Robin to enter without drawing attention.

Eventually, the Joker managed to take possession of a dirty bomb, which was big enough to take out half of Gotham City. Though Batman was able to capture the Clown Prince of Crime, the bomb wasn't with him; he sent Joker back to Arkham, and began figuratively and literally tearing apart Gotham to find the bomb. He followed any lead, clue or possibility that may lead him to the whereabouts of the bomb. However, the joke was on the Dark Knight, as the bomb was in the one place he would never look - Arkham. Joker hid it in Harley's mallet, which was in the basement of the Intensive Treatment building, with other confiscated property.

Assault on Arkham Incident

"Joker stole a dirty bomb and hid it somewhere. Batman has been tearing the city apart looking for it. At one point, he thought the Riddler might know where it is."

—Amanda Waller explains what Batman's been up to

Batman in Assault on Arkham

After tracking down the Riddler in order to learn the location of a dirty bomb that the Joker was planning to use, Batman saved him from Amanda Waller's guards and returned him to Arkham Asylum. A few days later, he discovered Harley Quinn vandalizing a department store. Harley claimed to simply be coveting a new line of dolls, her manic heartbeat making it difficult for Batman's Detective Mode to discern whether or not she was telling him the truth. Suspicious, Batman nevertheless left Harley for the police to return her to Arkham and unknowingly helped the Suicide Squad begin their infiltration of the facility.

Later he rescued a woman from Victor Zsasz. Returning to the Batmobile, he was contacted by Alfred about a "code yellow" at Arkham Asylum, though security footage showed everything to be normal until the presence of a guard who wasn't working that night told Batman it was being looped. Racing to the island, Batman found it on full alert and found the Suicide Squad breaking into the asylum's evidence room. A fight broke out, with Batman taking on the Squad's various skills and stolen weapons. He was facing off with Black Spider in the rafters when a huge explosion interrupted them. King Shark, Killer Frost, Deadshot, Captain Boomerang, and Harley Quinn fled the scene. "Black Spider" emerged from the wreckage, carrying Batman's Utility Belt as a trophy, and was apparently set to go down in history as the man who killed the Bat.

The Squad made it to the Medical Center as part of a plan to disarm the bombs implanted their necks with the Riddler's help. "Black Spider" stood guard while Riddler attempted to use voltage from the electroshock chairs to overload and disable the rest of the Squad's implants. Waller tried to contact Deadshot mid-process, realizing that she was being double-crossed, and attempted to blow the bombs. Tragically, only King Shark's went off, his super tough hide proving too thick for the shocks to work. This didn't explain why "Black Spider" was still standing, however. Batman, having switched costumes with Spider during the explosion, dropped the disguise just as the Joker burst into the room, opened fire, and spirited both Harley and her hammer away. Batman gave chase, but was temporarily taken out of action when one of Joker's bullets grazed his temple.

Recovered, he cornered Boomerang, Frost and Deadshot, who helped him realize the Joker had the bomb with him all along. Joker broadcasted to the asylum, announcing the bomb would be detonated and that all the inmates would be released for his "party". Batman helped subdue Bane and Poison Ivy, allowing the GCPD to force the other inmates back. Using Detective Mode, Batman noticed three heartbeats and the bomb in a passing GCPD helicopter, and proceeded to chase after them in the Batwing. The helicopter crashed into a skyscraper under construction, while Batman landed on the roof. Knowing the bomb was in Harley's mallet, Batman knocked her out and disabled it. He turned to find the helicopter falling, with the Joker pinned inside of it. The plane crashed, with the Joker somehow able to escape.

"Well, let's say I crack a lot of eggs to make an omelet.

And Because you're such a sloppy cook, the Riddler got away.

I'll get him next time.

There WON'T be a next time."

—Batman warns Amanda Waller

A day later, with Arkham back under control, but both Joker and Deadshot missing, Batman confronted Waller in her office and warned her to stop her games or there wouldn't be a next time.It's unknown if Batman knew Deadshot was ready to shoot Waller, who proceed to follow up on the warning; if true, it's possible he let allowed Lawton fire warnings shots to scare Waller into thinking about her actions.

Between Assault on Arkham and Road to Arkham

Knowing that the Joker wasn't dead, Batman searched for the Clown Prince of Crime, eventually succeeding in finding him and sending him back to Arkham Asylum. There, Dr. Young was tasked with treating him; however, the Joker managed to escape with Harley Quinn around Christmas a year later.

When Bane disappeared from Blackgate, Batman was under the assumption that the big brute has simply broken out and was laying low until he had a plan to go after him again. Unknown to Batman, Bane had been secretly released through Joker's connections and was shipped to Arkham for Dr. Young's research.

A year later, Batman prevented Gotham's citizens from being killed by deadly spores released by Poison Ivy's plants. Batman returned Ivy to Arkham, unaware that the Warden secretly wished to burn her alive.

"He fooled you Crane. You failed. Again. How does that make you feel? Humiliated? Scared?"

—Batman taunts Crane for failing

Batman was later contacted by Dr. Stephen Kellerman, who had been assigned to treat ex-Dr. Jonathan Crane AKA the Scarecrow. Kellerman had suspicions that Crane had somehow been sneaking his Fear Toxin in during their sessions, due to how increasingly paranoid he was getting; other than that, Crane was irritating because he believed that he was running their sessions, not the other way around. Batman, trusting the doctor's judgement conducted a blood test and found traces of the Fear Toxin, which Crane had in his cologne, devising an antidote. When Crane executed his plan to escape, Batman broke in and had the antidote sent into the vents. He couldn't help but mock Crane by asking if his failure had left him feeling scared.

At an unknown point in time, Batman would find Ra's al Ghul's corpse, which he sent to Arkham, where he hoped an examination of the body could explain how Ra's able to survive all these centuries.

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.

Batman having a discussion with Oracle on a pattern that he had seen in criminal activity of late.

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 accompanying Arkham's security guards as they transfer the Joker through the asylum.

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 trolley 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.

"He surrendered almost without a fight. I don't like it."

—Batman tells Gordon his observation of Joker

Batman clutching the Joker by the neck in an effort to prevent escape during his transfer in an Arkham 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.

"This is no simple escape attempt. Joker's been planning this."

—Batman's observation of the chaos in Arkham

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.

Batman rushing to Arkham North to defend the Batmobile from Joker's Henchmen

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.

"Bane called Dr. Young "bruja". What does it mean?

It's Spanish... for "witch""

—Batman answers Gordon's question, but is pondering his own

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.

Batman following the Joker's trail of destruction throughout all of Arkham Asylum.

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.

"Don't worry. I'll stop her, and her boyfriend."

—Batman's promise to Louie Green

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.

"What makes you think Poison Ivy will help?

If her plants are in danger, she'll listen."

—Batman is forced to seek unconventional help

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.

"Oracle, we've got a problem.

(Annoyed) What now? Riddler? Two-Face? Some kind of giant Joker robot?

Unfortunately, nothing that simple. Joker's pumping the waste product of the Titan production into the sewers. But why?"

—Batman sees Joker's backup plan

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 vegetation, 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.

"I'll never let you win. Never!"

—Batman to joker

Batman versus Titan Joker on the Penitentiary Roof

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.

Batman defeating Titan Joker

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

"I saw your incarceration on the evening news. Was getting yourself arrested part of your plan all along?

Not exactly, but it did get me some on-on-one time with Hugo Strange.

And how did that go?

Not good. He knows Bruce Wayne is Batman. He's says something called Protocol 10 will make him famous. I can't leave Arkham City until I know what it is."

—Batman warns Alfred about Strange

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.

Bruce Wayne putting on the Batsuit to become Batman on top of the Ace Chemicals building in Arkham City

Awakening, Bruce acknowledged Cobblepot, 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.

"Rumor has it he's been working with Joker, planning something special just for you. Maybe that's Protocol 10."

—Catwoman's intel isn't exactly helpful

Batman capturing Two-Face after he saved Catwoman

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.
