Mister Freeze's History
Before Arkham Origins Incident
Mr. Freeze was missing from the events of Arkham Origins that took place on Christmas Eve. However, Freeze was active for an unspecified time prior to his actions taken during Cold, Cold Heart on New Year's Eve. During that period, Victor put Nora into cryostasis to buy himself the time required to develop a cure for her terminal illness, Huntington's Chorea. Ferris Boyle approached Fries and worked out a deal: Fries would create cryogenic technology (mostly weapons) for GothCorp, and in exchange, Boyle would devote GothCorp resources to finding a cure for Nora. However, even as Victor held up his end of the deal, Boyle kept stalling on his. Victor eventually realized that Boyle was more interested in how he put Nora into cryostasis, which made him forget about their deal, and decided to do the research himself.
In response, Boyle and two guards attacked Fries in his lab and abducted Nora. In the struggle, Boyle knocked over a cryo-cannon, which froze one of the guards and hit a large container of cryogenic chemicals. The sudden pressure change caused the container to explode, and released a plume of chemicals that doused Victor and the remaining guard. Having been knocked away from the shockwave, Boyle managed to escape the plume and fled the lab, while leaving the others for dead. The guard and Fries struggled before the guard tried to flee also, but upon leaving the supercooled lab, he suffered a heat stroke and died at the doorway.
Victor witnessed the guard's death, and he realized that the chemical that he had been exposed to had changed his metabolism, and as a result, he would have to keep his body temperature at sub-zero in order to survive. Inside the lab, Victor constructed a makeshift cryosuit out of prototype parts in order to survive. It was noticeably less advanced than the suit Freeze had in Arkham City, as he built it out of spare parts in the lab and not the technology that he created years later.
Cold, Cold Heart Incident
Freeze arrived with Penguin's Henchmen, attacked civilians at Wayne Manor in the Ballroom at the Wayne Humanitarian of the Year Awards Ceremony on New Years Eve, and demanded that Ferris Boyle be brought to him. While Batman was able to keep Ferris safe for the most part, he encountered Freeze, who was able to freeze him, abduct Boyle, and escape. Batman followed him, and discovered along the way, that Freeze had equipped some of Penguin's men with cryonic weaponry. While Batman was trying to track down Freeze, he was able to find out that Freeze had struck a deal with the Penguin: he supplied Penguin and his men with weapons, and Penguin got him and Boyle into GothCorp. Once In GothCorp, the deal went sour. Penguin believed that Freeze was holding out on him due to Freeze's refusal to allow him into a certain section of the lab (in reality, it was a chamber that housed Nora). At that moment, Batman arrived to see a firefight between Penguin, his henchmen, and Freeze. Batman dropped down and picked off the two snipers, and while Penguin's henchmen were distracted, Freeze froze them all, retook Boyle, and created a wall of ice behind him, although not before he told the vigilante that his threats meant nothing to him as he "lost everything." Batman not only required his XE Suit (Extreme Environment Batsuit), but also a cryo-drill to break through the ice wall. The drill also needed a coolant that was developed by Victor Fries. In the abandoned lab, Batman finally discovered the truth about Freeze's transformation and found the coolant that was the same substance that Freeze used in his suit.
Batman returned to GothCorp with the cryo-drill and was able to access the chamber after he broke through the ice wall. After Batman fought through Penguin's henchmen and overloaded the cryo-generators, the Caped Crusader revealed he now knew the truth about what happened to Freeze as well as Boyle's role in it, and implied he'll make sure the police knew so Boyle would face judgment for his crimes. Boyle tried to deny it, causing Freeze to throw the CEO in a cryogenic stasis pod before turning to attack Batman again and declaring that nothing matters besides his rescuing Nora. Batman then attempts to appeal to his relationship to Nora by pointing out that she would never have wanted him to endanger lives for her sake. Freeze considers Batman's words and agrees that she wouldn't, and would much rather live a long life in the warmth of the sun while holding hands with him. However, he then decides that by this point, she'll have to settle with a man who, thanks to his accident and especially Boyle's role in it, has had his emotions run cold. Batman and Freeze then began a battle around the lab. Freeze's makeshift armor was too strong for Batman to damage conventionally, but he was able to find multiple ways to hurt him and disable the propellant tank on his suit. Their fight was interrupted by an alert that signaled that Nora's pod began to fail. Freeze flash-froze the room before he returned to Nora in order to fix the problem, and Batman was able to attack him from below as well as he activated his Thermal Gloves to break his dome and took him down.
However, as he incapacitated Freeze, Boyle freed himself and used the ruptured pipes in the room to freeze Batman, who pushed Victor out of the way. Ferris then snapped off a pipe from Freeze's suit and began to beat him to death, while he cruelly gloated that he could watch Nora die first and then him. Batman was able to free himself, however, and knocked Ferris out with two punches and told the corrupt CEO to " take a seat, humanitarian" in disgust. He administered the coolant to Freeze, and fixed Nora's pod, and thus, saved her life. Batman told Victor that while he couldn't give him peace, he could give him justice. He was arrested for his crimes, although because of the nature of his physical condition, he could not be sent to Blackgate due to it lacking the equipment needed to keep him alive at subzero temperatures, with it being implied this was ultimately a factor in reopening Arkham Asylum later on.
Assault on Arkham Incident
Freeze's Freeze Gun was found in the prisoner storage section of Arkham Asylum by Killer Frost and King Shark. Killer Frost attempted to use the Freeze Gun to kill Batman, but she failed. It was unknown when Freeze had constructed this version of the gun, as it was a stylized version of the one seen in Arkham City.
Road to Arkham Incident
Sometime before the Joker's control of Arkham Asylum started, Freeze escaped from his cell and fled Arkham Island. Exactly how and when he did this was unknown.
Arkham Asylum Incident
Freeze's cell, which was in the same wing as Arkham's most deranged cases, could be seen in Extreme Incarceration at the Penitentiary in Batman: Arkham Asylum, and could be scanned to unlock his biography. Other villains who escaped with Freeze during or before the chaos of Joker's takeover of Arkham Island were Riddler, Penguin, Bane, Killer Croc, Ventriloquist, Black Mask, Scarecrow, Catwoman, Calendar Man, Maxie Zeus, Humpty Dumpty, Prometheus, Tweedledum and Tweedledee, Great White Shark, Killer Moth, Mad Hatter, and Two-Face.
Between Arkham Asylum and Arkham City Incident
Freeze was going to continue his research only to be manipulated by Hugo Strange. Strange arranged to have Freeze's Cold Gun fall into Freeze's hands, allowing him to escape. Freeze made his escape and sought to get to Advanced Cryogenics in Gotham, where he believed his wife was being held. Freeze had decided on that day to escape as this was the day he believed his wife would be transferred into Arkham City.
While heading there he briefly encountered Batman, who gave pursuit in the Batmobile. Upon Freeze's arrival at Advanced Cryogenics, he saw Hugo Strange, who revealed that it had been him who arranged to have Mr. Freeze arrive there. He then proposed an alliance with Freeze. Freeze would get a fully-stocked laboratory where he could continue his research for Nora. In exchange, Freeze would have to manufacture an assortment of serums and medicines for him.
Freeze grudgingly accepted the offer, moving into the old GCPD building in Arkham City, but he swore to himself that he would cure Nora and have his vengeance on Strange. Eventually, Freeze became enraged at not having his wife with him. He then armed himself and set out to retrieve her, but he was ambushed by Tyger soldiers who had orders to take him to Hugo Strange.
He was then brought to Hugo Strange and forced to attend a session with him. He was asked to recount his origin from Victor Fries to the villain he is today. In exchange, he would be told where his wife is. He told the professor about the pets, Nora, Boyle, and Batman. In the session, Strange carefully directed the problems Freeze was facing back at him, pointing out that most of them could have been prevented or solved had he only done things a certain way. Eventually, Strange told Freeze that Nora was being taken to the Joker for "insurance", a fact which seemingly horrified him.
Freeze was later blackmailed by the Joker to find a cure for his Titan Illness. Freeze was easily able to develop a cure for the disease, but he found that it degraded too quickly to be used, and required a restorative enzyme. As part of the gang war, Penguin wanted to hurt the clown. He stripped Freeze of his suit and weapons. Freeze and his suit were displayed separately in Penguin's War Room and the Armory respectively. Penguin also stole Freeze's Freeze Gun for his own amusement and to torture undercover cops sent by Commissioner Gordon.
Arkham City Incident
"You will bring me Nora or you will die!"
—Mr. Freeze
Batman, who was poisoned by Joker with the latter's blood, went to find Freeze in order to get the cure. He discovered that the Penguin had kidnapped Freeze, and tracked him to the Museum. Batman soon found Freeze locked in a display case under a heat lamp, and was barely staying alive with the use of a plug that injected liquid nitrogen into his body, which kept it at sub-zero temperature. Batman interrogated Freeze for the cure, but Freeze required his suit and his freeze gun, and demanded revenge on Cobblepot. Freeze was reluctant to help Batman, but agreed after Batman threatened him by removing Freeze's life support. After Freeze gave into Batman's threat, Batman returned Freeze's nitrogen to him.
Batman got Freeze his suit and his freeze gun back and brought him the Penguin. Freeze got revenge by stepping on the Penguin's broken hand, only eased up when Batman told him to stop and locked the Penguin in one of his own display cases. Batman asked for the cure, but Freeze explained that it was too unstable for use. Batman realized that he needed to get the restorative element the cure required: a sample of blood from Ra's al Ghul. Freeze returned to the old GCPD Building at Amusement Mile while Batman went after Ra's.
After Batman recovered the blood sample, Freeze was able to complete the cure and quickly locked it away in his safe. Batman demanded the cure, but Freeze refused and destroyed one of the two vials of the cure. He informed Batman that Joker had Nora and Freeze ordered Batman to bring Nora back to him, and launched a full-scale attack against Batman. Batman was able to defeat Freeze and smashed the protective dome around his head to punch him, but stopped after a Joker hallucination from his worsening health.
When Batman attempted to retrieve the cure, however, he discovered that Harley Quinn was able to break into the safe and stole the other vial. Batman pursued her, at the insistence of Freeze, and agreed to also look for Nora. In exchange, Freeze gave Batman the Freeze Blasts that he had developed to help him break into the Steel Mill. Batman quickly found Nora in Warehouse 5B in the Falcone Shipping Yard at the Industrial District of Joker's Funland, informed Victor of her location, and reunited husband and wife. Freeze later appeared at the warehouse where Batman appealed to him to quit the life of crime and to focus on his wife.
Later that same night, Catwoman encountered Mr. Freeze attending to his wife. She sarcastically noted how nice it was that Batman had found Nora, a notion which Mr. Freeze agreed with. Catwoman then jokingly brought up the idea of a proposal for getting Mr. Freeze to help steal a Pharaoh's diamond from the Egyptian Museum. Mr. Freeze then asked her to leave him to allow him to tend to his wife.
After Arkham City Incident
Mr. Freeze, like many of the inmates of Arkham City, were freed when Hugo Strange's activities came to light.
Four months after Arkham City's closure, Freeze again resurfaced to aid Riddler's scheme to antagonize the Batman. He was defeated by Batman and later apprehended by the GCPD. At some point, Freeze was either released or managed to escape.
Before Arkham Knight Incident
Freeze eventually took Batman's advice to leave the criminal world and focus on his wife's cure, and set sail on her namesake ship. After months of work, Freeze was finally close to a cure, only a few days away. Scarecrow, however, still wanted Freeze to help in his final assault on Gotham City, and wanted him to personally capture Batman. Freeze refused the offer, and chose instead, to focus on the cure. In retaliation, Scarecrow sent the Militia to kidnap Nora. In the attack, the ship's Cryo-Generator was damaged, and Victor was forced to stay on board and repair it rather than going after Nora and risk losing the cure.
Arkham Knight Incident
BATMAN™ ARKHAM KNIGHT 20160313214303
When Batman arrived, Freeze pointed his new wrist freeze gun at Batman and blamed him for the Militia kidnapping his wife. Batman told Freeze to shoot him if he trusted them. Freeze stood down and begged for Batman's help, and, in the process, made it clear that he blamed him for his current crisis. Freeze gave Batman a device that could lead him to Nora's cryo-chamber before he returned to his work.
While Batman was out searching, Freeze continued his attempts to repair the generator before it could detonate until he was distracted by a call from Batman that alerted him that Nora was awake. In a panic, Victor left his station and inadvertently allowed the generator to reach critical mass. He was distressed to see wife out of her containment unit. He begged Batman to put her back in, while he worked on the cure. She cried saying, "Don't you see? I don't need saving." At that moment, the generator malfunctioned, freezing Gotham Bay and causing it to snow across the city. The Militia took advantage of the newly frozen bay by launching a colossal assault of drones on the ship. Working together with Nora in tow, Batman and Freeze were able to slow the siege but were quickly overwhelmed. Freeze then had to make a choice: allow the generator to explode and take out the Militia, but lose his cure and all of his work in the process, or let himself and Nora be killed by the Militia then and there. Victor detonated the generator at Nora's request, wiping out the drone strike.
With the siege over and his life's work gone, Victor begged Nora to let him freeze her again so he could resume his search for a cure. Nora explained that she would rather live out the rest of her days with Victor than be frozen for another decade, being unable to do anything but witness her husband's descent into villainy and madness. Victor realized that she was correct, agreed, and the two vowed to spend their few remaining days together.
Victor and Nora were last seen holding hands on the bow of the ship, and their time in Gotham was over.
