Professor Hugo Strange first gained fame as a psychiatrist who declared that he had fully analyzed the Dark Knight from afar, and later lent credence to his own claims by deducing Batman’s true identity as Bruce Wayne. However, his interest in the Batman turned into a deranged obsession, and he used his medical expertise to hatch a series of bizarre plots based around genetics and mind control in order to defeat the hero and possibly take his place as Gotham's savior.
Before Arkham Origins Incident
Hugo Strange studied to become a psychiatrist who specialized in analyzing the criminal mind, and it was possible that Batman already caught his attention.
Arkham Origins Incident
Strange, at the beginning of his career, worked as psychiatrist at Blackgate Prison, where he treated its inmates (such as Alberto Falcone). Harleen Quinzel interned under him, before she transferred to Arkham Asylum. It was unknown whether or not Strange had begun his Arkham City plan around that time, although Shiva's involvement in the incident suggested that Ra's al Ghul had.
Between Arkham Origins and Road to Asylum Incident
Strange was still a new and relatively unknown player to Gotham City. Although he was a licensed psychiatrist, little else was known about Strange's origins since he had been shrouded in mystery for years. Early on in his career, Strange became obsessed with Batman and dedicated his life to finding out more about Gotham City's greatest protector.
Apparently, after spending years intensifying his studies on the one topic, Strange also became intrigued with Batman's perfect code of justice--no one died by his hand. He also longed to become the Dark Knight himself, and to inherit the legend of such a crime fighter. With such a cunning mind being put to work, it wasn't long before Strange used his skills to discover his subject's secrets, including his alter ego as billionaire playboy, Bruce Wayne. Strange would later use that knowledge by slowly setting the stage in Gotham for the ultimate challenge: to first destroy Batman in a one-on-one chess game with his city as the board, along with friend and foe as pawns, then take over as the Caped Crusader himself and use the identity for his own purposes.
One of Strange's psychiatric patients was Warden Quincy Sharp, administrator of Arkham Asylum for the Criminally Insane, where most of Batman's Rogues' Gallery were kept. Strange soon found Sharp to be the best kind of puppet: established, old-fashioned, affluent, and completely hollow. He was a blank canvas, fit for someone else to manipulate. Over a period of three years, the warden found himself programmed into becoming Strange's "face", and was being used to set the stage for a showdown with the Masked Manhunter. One of Strange's first moves was to make Sharp run for Mayor of Gotham City, and knew that if the asylum warden won the position, it would give him almost unlimited influence over the city.
Arkham Asylum Incident
Strange's files could be found in the Arkham Records Room at the Arkham Mansion during the Joker's takeover, which suggested that he still worked there or he forgot to take them away. Those plans were almost set back by a massive riot at Arkham Asylum that was carried out by the Joker, the Clown Prince of Crime, who freed most of its deranged inmates and took over the institution for one night before his scheme was thwarted by Batman himself. With his security systems disabled, his private security force completely routed by the rampaging patients, and chaos spreading across the locked-down Asylum, Sharp's public image was nearly derailed for allowing such an incident to happen. However, quick-witted Strange was soon to exploit such an opportunity, and who declared that once the riot had been suppressed, that the warden was the one who was solely responsible for stopping the Joker, which gave Sharp enough public support to make his successful bid for Mayor.
Now, with such a madman finally in control of the "board", the pieces of an ingenious and insidious plan to destroy the Dark Knight began to fall into place.
Between Arkham Asylum and Arkham City Incident
Strange retreated further into the shadows once the then-Mayor Sharp was introduced to the public spotlight as his "public face". Strange stayed in contact with his pawn mainly through the occasional phone counseling session, and directed his every word in public through a radio receiver that was implanted in Sharp's ear.
Sharp was able to keep a strong resolve with Strange's manipulation guiding him into declaring Gotham City a war zone. He instituted a new prison system for all criminals after several rogue members of Two-Face's Gang destroyed Gotham City Hall with a bomb, and killed more than three hundred citizens in the process. It was implied that Strange had planned that incident all along from his position behind the scenes, and thereby came up with a pretext to put Gotham City under martial law and began to run it like his own police state.
With Arkham Asylum and Blackgate both declared as unfit to house criminals, a drastic new project was introduced with the broad mayoral powers at Strange's disposal: Arkham City. Arkham City, in fact, was nothing other than a hellish anarchic nightmare with dozens of the worst criminals, simply thrown into a walled-off lawless district where everyone could forget about them.
Strange, of course, finally came into the limelight when Mayor Sharp placed him at the helm of the new project, and delegated to him full authority over both the project and its staff. In addition to the repeat-offenders and criminally insane mental patients, hundreds of innocent people were also rounded up and locked into the prison city, even those that had only minor records. To prevent the Arkham City denizens from escaping, a new security force was formed out of professional mercenaries and former military. The team, made up of well-paid former military and police operatives, was codenamed "TYGER" and was subsequently turned into Strange's personal squad of trained assassins and enforcers.
Mayor Sharp's dictator-like stance soon compelled the public to loathe and fear him. None except Batman, however, suspected that Sharp was merely the front man for a much more insidious plot that was orchestrated by an outside power.
Arkham City Incident
Because of the secrecy involved in Arkham City and the frequent challenges with Mayor Sharp, Bruce Wayne entered into the political arena to challenge the necessity of Arkham City and questioned its existence. During a live press conference attended by both Vicki Vale and Jack Ryder, Strange ordered a squad of Arkham City's TYGER Guards to storm the press conference and take Wayne prisoner. They accomplished their mission, and delivered Wayne to Strange where he proceeded to experiment and torture the man with electric shocks. During that, Strange revealed to Bruce that he knew the truth about his secret identity as Batman and that he would reveal it to the world if he tried to stop him or his personnel in Arkham City. With Protocol 10 soon to be enacted, Strange had Wayne thrown into the prison where he became a target and would, theoretically, be killed by the various gangs.
Wayne was sent in with Ryder and another, unidentified, prisoner, and Strange watched and announced their new arrival to the citizens of Arkham City. His attention was soon diverted, and intercepted by Bruce, with the news that Catwoman was about to be executed by Two-Face. While Strange saw it as inconsequential, Bruce set off to stop the assassination as Batman. When he was caught by a TYGER helicopter, Strange quickly ordered that Batman was harmless and that he was to be ignored as he was not important at the moment.
In his preparations to enact Protocol 10 and destroy Batman, Strange devised a series of mind games in order to break the Caped Crusader. Seeing as Crime Alley was firmly entrenched within the walls of Arkham City, Strange prepared a cruel surprise for Batman at the scene of the murders of Thomas and Martha Wayne, in anticipation for the Dark Knight's arrival.
When Batman arrived in Crime Alley after being trapped within the superprison, he would find the chalk outlines of his fallen parents redrawn, a single red rose, an audio tape, and a bouquet of flowers with a card promising that "IT WILL END WHERE IT BEGAN". As Bruce knelt in mourning at the scene, he played the tape left for him by Strange, in which the Professor openly mocked Wayne and his inner turmoil, concluding by gloating that anticpated seeing him broken. Even with this confidence in his victory, Strange never addressed Wayne as Batman, still jealously guarding the secret for himself.
Soon after he realized that he'd outlived his usefulness, Strange ordered Sharp arrested by his security forces to get him out of the way. Strange had Sharp dumped into Arkham City where he quickly became a target of the various gangs because of his previous affiliation with Arkham Asylum and the rumors that he had abused the inmates. To ensure that Sharp became a victim of the lawlessness, Strange publicly announced his location over the announcement system, but thanks to Batman's continued bravery, Sharp's life was spared.
Two hours later, Strange intentionally called an emergency meeting of the Gotham City Council where he informed them of a dangerous arms race within Arkham City and that Protocol 10 was the only option available. That "arms race" was essentially planned and orchestrated by Strange (as proven by a phone call from Joker) through him secretly delivering weapons to Joker, Penguin, and to some extent, other inmates. Strange then enacted Protocol 10: the systematic destruction of Arkham City and the slaughter of all of the prison's inmates. TYGER Assault Helicopters broke off of their patrols and started tracking down any and all of the prisoners that they could find. Missiles were launched deep into the heart of Arkham City, and hit the Museum, the Steel Mill, and the Solomon Wayne Courthouse directly. While Batman was set to pursue Talia al Ghul in order to rescue her from Joker, at the pleading of both Alfred and Oracle, Batman went to stop Protocol 10 and Strange instead.
Strange also ordered his TYGER Guards to invade both Wayne Manor and the Batcave, while Batman was heading to Wonder Tower to stop him. Nightwing, Robin, and Alfred protected the Manor from them. After Batman arrived at the base of Wonder Tower in the Arkham City Processing Center, Strange communicated with him via viewscreen, while he held a syringe to a hostage. Strange then began to psychologically toy with Batman, while dozens of TYGER Guards surrounded the Dark Knight. The Professor proceeded to tell the vigilante that his very existence was what cause of all the madness and crime in Gotham, and pointed out even the creation of The Joker was Batman's fault. Strange concluded that this was why he had risen to power, and that soon he and his "Master" would rule the entire world. Thanking Batman for his help, the Professor ordered his TYGER Guards to kill the Dark Knight, and despite overwhelming numbers and continuous reinforcements, Batman eventually bested them all. As Batman ascended to Wonder Tower, Strange broadcasted to all of TYGER, and stated that once the population of Arkham City had been eradicated, they would move onto Phase Two, being the creaton of further facilties in both Keystone and Metropolis, likely with similar goals to Arkham City - the total eradication of crime.
Evntually, Batman confronted Professor Strange in the Command Centre of Wonder Tower and, after he knocking him down, connected Oracle to the computers to shut down Protocol 10. Batman then shoved Strange's face against a window to gaze upon the destruction that he had wrought, but Strange expressed sadistic satisfaction at his handiwork. Batman then declared that he had him beaten as Protocol 10 was deactivated. Strange then defiantly gloated that he would soon "command forces beyond [his] comprehension". His gloating was short lived, as he was stabbed through the back by none other than Ra's al Ghul with his sword, who was revealed to be the secret benefactor of Arkham City. Mortally wounded, Strange told Ra's he had done everything he wanted him to do, and begged him for more time to achieve their goals. Ra's denied Strange this, telling him that Batman had proven himself superior to the Professor, so proving he was unworthy as his sucessor as Head of the Demon.
As Batman held the dying Professor, he insisted he get him medical attention. Ra's refused this, instead looking out over Arkham City as it burned. Realising his betrayal, Strange ordered his computer to enact Protocol 11, the systematic destruction of Wonder Tower. In his final moments, Strange breathed the passcode: "Wayne". Batman threw himself and the enraged Ra's al Ghul from the Tower moments before it exploded, with the Head of the Demon being killed himself shortly afterwards.
With the deactivation of Protocol 10 and the death of their leader, the TYGER forces ceased their attacks on Arkham City and its inmates, marking Professor Strange's final defeat, and failure.
Between Arkham City and Arkham Knight Incident
In a Gotham Story, Strange manifested himself as a hallucinatory ghost who appeared before former Mayor Quincey Sharp in prison. In Sharp's hallucination, Strange told him that he had one more task for him and instructed him to remove his bed sheet and hang himself with it. Sharp complied, and as such eradicated all available evidence of Strange's background and past.
Arkham Knight Incident
Hugo Strange was dedicated to understanding the workings of the human mind, no matter what it took. Strange had very little remorse for his actions, given that he let the Mad Hatter experiment on the forgotten patients to perfect the drug he used to mind-control the TYGER Guards and Quincy Sharp. After he came in contact with Ra's al Ghul, Strange became dedicated to wiping out the criminal element in Gotham, and planned on repeating the process in both Keystone and Metropolis, and probably more cities besides. That also gave Strange an inflated ego, since he had figured out Bruce Wayne's secret identity, and was a candidate to replace Ra's as the head of the League of Assassins.
Strange possessed a malignant and sadistic mind, though he was dedicated to his work as a psychiatrist he seemed to perform his experiments with a smile on his face and taunted Batman as he made his descent on Wonder Tower, making threats to attack his allies after the success of Protocol 10. His egomaniacal traits were showcased by how he once referred to himself in the third person and made speeches in his own honour, all regarding his superiority over Batman. Strange is thoroughly unethical in his dedication to understanding the aspects of criminology and the criminal mind in general so he could use this information to advance Protocol 10. He sent innocent doctors to treat the Joker, fully knowing it would result in their deaths so he could satisfy his thirst for knowledge regarding the Joker's backstory and threatened the life of Catwoman's friend, Holly to force her to comply during the Interview Tapes. He also didn't know what it is like to love another person, as shown when he replied a simple no to Mr. Freeze's question about the subject.
Beneath his arrogant demenour, Strange was also somewhat insecure. His obsessive and maniacal mind caused his deteriorating psyche and his fixation on Batman which went far as to create his own Batsuit that he wears while weeping in his hands. Strange's obsession with Batman projected a desire to not only be Batman but outshine him in any way, joining forces with Ra's al Ghul he masterminded Protocol 10 to eliminate all criminal element in the world, a more extreme version of Batman's goals to bring peace to Gotham. Strange does not see any fault in his actions or himself as in his mind he is the hero of the story. He does, however doubt himself especially regarding how worthy he might be to the mantle of Batman which Riddler informs of him.
Whilst he was a psychiatrist, Strange was furthermost known for his outright callous and sadistic disregard for his own patients. In his goal of obtaining knowledge of the human mind he was quite immoral, ruthlessly blackmailing, dominating and controlling his patients to gain information, even forcefully getting them to relive painful past experiences simply to sataify his own needs. After he became in charge of Arkham City, Strange began showing even less concern for the inmates, occasionally leaving them without food or allowing others to experiment on the Arkham Asylum Lunatics.
His greatest ability was his powerful intelligence and ability to manipulate others. He bribed the mentally unbalanced Jervis Tetch with his hats at the Asylum and feeding his illusions of Alice, forcing him to perfect his mind control serum. After which he repeatedly drugged the Mayor Quincy Sharp, manipulating him into making Strange in charge of Arkham City. He made several failsafes in the chance of a mass breakout, especially Protocol 10 which would eradicate the entire criminal population of Arkham City and then proceeds to exacerbate the gang war by providing them with military-grade weaponry and makes it appear as if Arkham City was lost when in reality he purposefully gave it to the criminals so he could complete Ra's al Ghul's purpose of destroying all criminal life.
It is entirely possible that Strange has accepted the League of Assassins beliefs since encountering Ra's and his twisted philosophy. He shows genuine hatred towards criminals, sadistically watching the carnage of Protocol 10 whilst claiming it was "glorious". He does not seem to match Ra's to a degree of zealotry but moreover believes their deaths are for the greater good of Gotham and other cities. On the other hand, Strange's goals are extremely self-centred as he was using the League of Assassins code to prove his superiority over Batman.
In Arkham City, Hugo Strange was shown as a tall and somewhat muscular man with a thick grey beard and a completely bald head. Strange wore a pair of tinted round glasses and a white knee-length medical coat bearing the Arkham City logo, as well as his Warden's badge. In addition, Strange also wore black pants, black gloves, and black shoes.

Arkham City Speeches/Announcements
- "You are mine, new inmates. Let me introduce myself: I am Professor Hugo Strange and I am in charge of the Arkham City Facility. Up until this point, you have shown total disregard for the law, for society, and yourself. From this moment on, you are no longer part of the society that you have shown no respect for. You have been separated from the good people of Gotham. By committing the actions that resulted in you being sent here, you have given up the right to a so-called normal life."
- "While in my custody, you will follow the rules of Arkham City to the letter. These rules ensure your continued well being. Rule 1: Do not approach the security wall surrounding the facility. Any attempt to approach the wall will be considered an act of escape and will be met with extreme force. Rule 2: All prisoners must surrender themselves for full psychiatric examination when requested. Failure to surrender will be met with extreme force followed by a level nine and ten psychiatric profiling. Rule 3: TYGER operatives have full jurisdiction in Arkham City. If for any reason a TYGER operative approaches or issues an order to you, you must immediately adopt a kneeling position and place both hands on the back of your head. Failure to adopt this position will be considered an aggressive response and will be met with extreme force. These rules are mandatory and by the power vested in me, by the people of Gotham City, lawful."
- "Arkham City provides regular food drops at designated points throughout the day. Food drops will only occur at these times and in these locations. Prisoners are responsible for ensuring that food is distributed fairly."

Batman: Arkham Asylum
Batman: Arkham City
- The corpse of the TYGER Guard that was tortured to death by Strange in the cinematic trailer could later be found as a riddle in the actual game. Next to the body, there was a jar of blood with the label, "Drink Me", on it. That was the same label from a jar of the Joker's poisoned blood that Joker showed to Batman earlier in the game. The connection between the two items in terms of plot relevance was unknown.
- Origins revealed that Strange was a Blackgate psychiatrist in Arkham Origins and that his intern was Harleen Quinzel. This was never mentioned in the previous two games, and could count as a continuity error, as one would assume that Harley was familiar with Strange and his deceptive nature (working as an extortionist), but never informed Joker despite potentially fatal consequences.
- Strange's appearance changed between Asylum and City. In Arkham Asylum, Batman's files of Strange depicted him as a muscular man in a more militaristic outfit, but in Arkham City, Strange was shown to be skinnier and fragile, and wore a white lab coat instead of the green Asylum uniform.
- Even after the player finished the Main Story, Strange still spoke when you looked at the Hush Side Mission on the map (his voice was most likely a recording).
- Strange foreshadowed numerous events by saying: "It will end where it all began...". He could have meant that Batman will die in Gotham City, the Joker would die where Bruce's parents were killed, Batman killing the Joker in a dream at Crime Alley, or the supposed death of Batman at the end of Arkham Knight.
- The Riddler's Interview Tapes that were unlocked in Arkham City, revealed that Strange kept an imitation Batsuit in a secret compartment that was hidden in his office. When alone, Strange opened the panel behind his closet, donned the costume, and lamented whether or not he was truly worthy of seizing the mantle of Batman. This is a reference to Strange's obsession with Batman in the comics, where he sought to replace the Dark Knight as Batman, even having his own Batsuit for such an occasion.
- Strange's affiliation with Ra's al Ghul was actually foreshadowed by his Game Over message, where he stated: "So, you failed to live up to his expectations. How predictable." The "he" here was Ra's, and served as an early indication that at the least, Strange was in collaboration with someone who thought highly of the Dark Knight. This is foreshadowed further with Ra's' own Game Over message of "You disappoint me, detective."
- The plot of Arkham City was actually a subversion on Strange's general M.O. In the comics, Strange had, on numerous occasions, been depicted as a man so absolutely obsessed with Batman that he wished to replace him. In Arkham City, that was changed so that Strange sought to replace Batman as Ra's successor, and also to replace him as "Gotham's Savior" by succeeding where Batman had failed: by completely eliminating all of Gotham's criminal population. "Gotham's Savior" was, fittingly, also the password to Strange's control room, where Protocol 10 was operated from.
- The above would also explain why unlike in Arkham Asylum and many interpretations, Strange wasn't seen as a physical threat the way Batman was. Instead, Strange was a purely psychological and cerebral threat, because his motive in replacing Batman was not to literally become Batman, but instead to accomplish what Batman sought to accomplish with a more "off-hands" approach.
- Despite not being regarded as official canon, it was worth noting that a major continuity error was featured in the novelization of Arkham Knight on page 59. Oracle implied that both Victor Zsasz and Hugo Strange were apprehended for attempting to blow up Gotham Central Station, and did not acknowledge that Strange died during the events of Arkham City.
- Strange's line "Your presence creates these animals" actually holds some value. Batman is indirectly responsible for Joker and thus Harley Quinn, Black Mask's downfall which allowed Penguin to take over, Two-Face's scars, and The Arkham Knight.
- Strange is the only villain who can be heard in another villain's Game Over scene, repeating his "The great Batman has fallen" line when Deathstroke defeats Batman in Arkham City Lockdown.
- Despite knowing that Batman was responsible for their creation, the security systems in Arkham City consist mainly of Waynetech systems. Given that he was funded by a criminal, it's unclear why he would use systems that Wayne could easily bypass.
