How can the world know fear--true dread--when it has you? A stalwart knight, ever ready to slay monsters. Fear isn't pure biology, Batman. It's more than instinct. True fear is the absence of hope. And hope is the spread wings of a Bat, shining on the clouds.
— Scarecrow to Batman

Taunted and bullied in his youth, Jonathan Crane vowed to overcome his fears through the study of psychology and biochemistry on phobias and the nature of fear. Kicked out of the university he taught at for experimenting on human subjects, Crane adopted the identity of the Scarecrow, and armed himself with a specialized fear-inducing gas that makes a person's deepest phobia become a frightening reality. Scarecrow's ongoing reign of terror makes him one of Batman's most recurring and psychologically dangerous foes.

When The Joker took over Arkham Island, Crane was released to cause as much death and chaos as possible. Using this to his advantage, the Scarecrow tried breaking the mind of Batman again and again, only to fail. When attempting to poison Gotham City's water with his toxin, Crane was brutally mauled by the mutated criminal, Killer Croc.

Seething with rage, Scarecrow exacted revenge on Batman and Gotham with his allies, the mysterious Arkham Knight and former assassin, Deathstroke. However, in the end, Crane's plan to break Batman's will failed, and he was forced to endure a dose of his own improved toxin. Reduced to a harmless shell, Scarecrow was left to suffer visions of bats.

He served as the tertiary antagonist of Batman: Arkham Asylum, and one of the main antagonists of Batman: Arkham Knight.

Incident Reports

Before Arkham Origins Incident

Born Jonathan Crane, he was the meek but intelligent child of a normal Gotham family. Unfortunately, he suffered years of bullying, which caused him to be in a constant state of terror. Deciding to overcome his phobias, Jonathan dedicated his life to studying fear. Jonathan became a professor of psychology and psychiatry to overcome his fears of being teased by his classmates for his obsession with his studies.

Eventually, he decided to get a job at Blackgate Prison to research fear and nightmares. Crane then made a gas that induced fear in his patients, believing that criminals were the perfect subject for his tests as they were effectively the embodiment of his childhood bullies. Crane ran his tests on the prisoners at the prison to improve his toxin.

Between Arkham Origins: Blackgate Incident and Arkham Asylum Incident

Eventually, Crane was found out and fired. Seeking revenge, he adopted the identity of the super villain Scarecrow to get back at his former employers via his Fear Gas. This brought Crane into conflict with Gotham's protector, Batman. To Crane's amazement, Batman wasn't visually affected by his Fear Gas, and subjected to a dose of his own "medicine" before being arrested. Once recovered, Crane became intrigued with the idea of a man who had no fears, deciding to focus on breaking the Batman along with the rest of Gotham. To this end, Crane researched relentlessly to create a batch of Fear Gas that could even break the Dark Knight.

Over the years, Crane repeatedly broke out of Arkham Asylum, hoping with each chance to infect the citizens of Gotham with his Fear Gas to study their fears; as an added bonus, this would lure in Batman so Crane could douse him with his Fear Gas. However, he was repeatedly bested by Batman and subjected to his Fear Gas again and again over the years. This had an unintended side-effect on his self-preservation cortex (the part of the brain that controls the survival instinct/fear). Crane was gradually beginning to lose his own sense of fear, increasing the instability of his mind; however, due to Batman being what he saw when infected by Fear Gas, Crane retained a fear of bats no matter how much his own immunity to the toxin increased.

Assault on Arkham Scarecrow

Scarecrow escaping in Batman: Assault on Arkham.

Even though Scarecrow was returned to Arkham, he continued his plans from a secret loft that was hidden at the Intensive Treatment Center, and plotted his next move with some stolen blueprints of the Asylum. In secret, Scarecrow managed to hide three canisters worth of his Fear Toxin in Arkham West; unknown to him, The Riddler would discover the cache and make it one of his riddles for Batman. Scarecrow was later incarcerated at Arkham Asylum as the Suicide Squad arrived. Crane managed to escape when the Joker let everyone out of their cells, allowing Crane to infect officers with Fear Toxin and escape. Though he was eventually recaptured.
You're all part of my experiment now!
— Scarecrow

While incarcerated, Crane was assigned to Dr. Murphy for treatment, but was later sent to Dr. Combs. Managing to sneak in some of his Fear Gas, Crane broke Combs. As Combs saw horrifying visions of the deaths of his family, security arrived and captured Crane, who noted that it was impossible to continue his research with the Arkham staff impeding him at every step.

Three weeks later, Crane was referred to Dr. Stephen Kellerman. Despite Kellerman's attempts to treat him, Crane acted as though he were conducting the sessions, even dictating notes, and was simply patronizing him. Crane toyed with Kellerman during each session, shared his philosophy on fear as the driving force behind the human condition, and even used everyday examples from the therapist's supposedly fulfilling life as evidence.

These meetings rattled Kellerman, who came to believe that Crane was simply sadistic rather than insane (with there not being much difference). Crane's mind games were actually having even more of an effect on Kellerman due to the Fear Toxin chemicals he had incorporated into his cologne, and was also exposed to the guards who brought him to each session. This was part of a plan to further Scarecrow's research, who rigged the Medical Facility's air conditioning system to flood the building with the rest of his latest Fear Toxin formula. Everyone exposed to both components began to hallucinate their worst nightmares.

Before Crane could continue, Batman crashed into the room. Kellerman had realized what his patient was up to, and provided the Dark Knight with a sample of the toxin to create an antidote, which he gave to Arkham Asylum Guard Aaron Cash to disperse through the rigged air conditioning system. Scarecrow was amazed that Batman seemed to be unaffected by the gas, then gleeful when he implied that he was being affected as much as anyone else. Despite his pleas to learn what kind of vision his nemesis had seen, Crane was defeated, arrested, and returned to his cell, and lost once again to the Dark Knight's willpower.

Arkham Asylum Incident

There is no Crane... only Scarecrow!
— Scarecrow
Ark mans Scarecrow 01

Scarecrow's Fear Gas at work in the Secure Access Corridor at the Medical Facility.

Scarecrow was one of the Arkham inmates on the Joker's "party list", and who was released during the Clown Prince of Crime's takeover of Arkham Island, both to distract Batman and for the Joker's general amusement as Crane's experiments often left his victims dead of heart attacks. Crane made use of his secret stash of Fear Toxin, intending to break Batman this time. It's suggested by a fake patient session the Joker had with Batman, that Crane had been studying Batman with him; both were confused as to why Batman hadn't snapped, and come over to their side yet.

Batman tracked a kidnapped Commissioner James Gordon to the island's Medical Facility. While Batman saved the staff, Joker mentions Crane as one of two "old friends" coming to the party - "one will be absolutely terrified if you leave without saying hello." After he rescued the staff, Batman took out a raiding party of henchmen before he took the elevator to the lower levels to follow Gordon's forensic trail of tobacco. The Joker taunted Batman through the Asylum's CCTV system, and considered to just release the elevator from its cables, as a joke. As Batman made his way into the basement levels, he began coughing on a colorless gas being remotely pumped into the elevator; "prepare to face your greatest fears... All of them!"

Scarecrow had already gone to work with torturing new victims for research data; having injected them with his Fear Toxin, he watched as they all died of heart-attacks before fleeing into another part of the building. Noting that the "good doctor" had started work early, Joker laughed that Batman would be buzzed through for his "appointment" when Scarecrow was ready, going on to ask what the Dark Knight feared most.
Scarecrow (1)

"And at the end of fear...oblivion!"

Batman used the vents to bypass the doors, finding Commissoner Gordon calling for help through one of the grates. Moments later, Batman emerged from the vents to find the corpse of his dear friend. His mind reeling from one of his greatest fears, Batman attempted to hunt Scarecrow down, only to find himself in the Morgue, where he was confronted by the animated corpses of his parents and a twisted obstacle course that was overseen by a giant, omnipotent Scarecrow. After he realized that he was experiencing a Fear Toxin hallucination, Batman overcame the delusion by avoiding the delusional Scarecrow's fiery gaze, used a Bat-Signal as a symbol of his willpower, and shined its light directly into Scarecrow.
Had a little run-in with Scarecrow, slowed me down. I'll get back to you in a bit.
— Batman comforts Oracle
Batman returned to his senses, just in time to discover that Scarecrow was long gone; the most likely explanation is that the Fear Toxin in Crane's syringes had run out, and he needed to refill them before making another attempt to break Batman. The Dark Knight returned to the corpse he thought was Gordon, but found it was actually a security guard; the Fear Toxin had affected Batman's mind more than he had thought.

Batman in Scarecrow's Second Nightmare.

Over the course of the night, Batman uncovered the mystery of the Titan Formula and investigated the Arkham Mansion to find either Dr. Penelope Young or to destroy her notes. He managed the latter, but the Joker wasn't outdone yet, and sent Victor Zsasz after Dr. Young. Batman raced off to find her, but was gassed by Scarecrow again. This trapped Batman in a hallucination of the night that his parents were murdered as his nine-year-old self, walked down a seemingly never-ending hall that turned into Crime Alley. He overcame this part of the delusion by remembering the kind words of a younger Gordon, returned to his adult state, used all his skills to once again avoid the Scarecrow's gaze, and illuminated him with the Bat-Signal. Batman managed to free himself a second time, discovering that he had gotten himself trapped inside the belfry. This also made him too late to prevent Zsasz from taking Dr. Young hostage in Warden Quincy Sharp's Office.

Did anyone catch the game last night?
— Intercom

As the night wore on, Batman learned from Poison Ivy of a plant spore in the Asylum's sewer system that would help him concoct an antidote to the Titan Formula and returned to the Intensive Treatment Center to retrieve it from Killer Croc's Lair. As Batman made his way to the elevators, he began coughing on the Fear Toxin again and experienced a strange kind of vertigo: his vision was filled with static to the distorted sound of the Joker's laughter. At this point, Batman began reliving the earlier events of the night, but in Joker's place.

The Joker arrived at Arkham in the Batmobile, and took Batman to the Intensive Treatment Center. Batman ranted and raved, insisted that he hadn't killed that family, and demanded to be cut free. He resisted Crane's attempts to examine him, who then declared him a lost cause and left him to the Joker's mercy. The Joker leveled his gun at Batman's head and fired at point-blank range.

"I think you need a little more!"

After he realized that he was suffering yet another Fear Toxin hallucination, Batman climbed out of his own grave and made his way past the cells that were full of other insane Batmen to find the Bat-Signal. Just like last time, Crane made Batman see him as an omnipotent giant that could kill him with a single palm strike; he even called in henchmen to attack him, but Batman beat them easily. About to break Batman's mind, Crane was shocked when Batman shined the Bat-Signal.

With Batman free of the illusion, he grabbed Crane by his hood. However, Scarecrow jabbed his syringes into Batman's gauntlet, giving the Dark Knight more Fear Toxin to fight off. The illusion now had the giant Scarecrow watching Batman resist numerous attackers, which included two henchmen injected with the Titan Formula. With Batman occupied with his hallucinations, Scarecrow fled into the adjacent corridor; the bars would keep Batman at bay the next time he broke free.

Every time Batman defeated a number of enemies, one of the three Bat- Signals would activate and damage Scarecrow. Batman prevailed yet again, and defeated as many skeletal warriors as needed to strike Scarecrow with the three Bat-Signals. Scarecrow was left shocked by these turn of events, as Batman was once again gripping his hood through the bars; he gave Batman another quick jab of toxin, buying himself time to flee to the elevator with a pouch full of his toxin.

"You've ingested enough toxins to drive ten men insane. What are you?"
— Scarecrow defeated and wondering if Batman is even human

As Batman regained his senses, Crane taunted him, asking why the Dark Knight couldn't see that the relationship between him and the super criminals was symbiotic - they need each other. Crane rode the elevator all the way down to the lowest level, to reach the sewers; he didn't know that the sewer system served as the lair of Killer Croc. Joker's Henchmen locked the way back up behind him, hoping Crane would get eaten by Croc, as they find him creepy; however, Batman pummeled them and unlocked the path.

As Batman examined a Titan-mutated plant, Scarecrow warned him to stay away, or he would drop the bag of Fear Toxin into the underground river; the cave would fill with all Batman's worst nightmares. Worse, the Gotham water supply would be contaminated for over 100 years due to the potency. Before Scarecrow could make good on his threat, Killer Croc burst from the water and grabbed Crane, having mistaken him for a guard, a stray inmate, or Batman. Scarecrow lost his grip on the Fear Toxin, letting drop harmlessly to the ground.

Scarecrow dragged into the river by Croc.

Fearing for his own life, Scarecrow flailed hopelessly to get free of Killer Croc's grip. Right as the monster was about to take a bite out of him, Crane was saved from that gruesome fate by Batman, who had managed to toss a Batarang at Croc's electric shock collar to activate it. Though the zap from the shock collar stopped Croc from trying to eat Scarecrow, he still refused to let go. Instead, Croc jumped back into the water, dragging the screaming madman with him.

To Scarecrow's bad luck, the shock collar's zapping was something that angered Croc. In retaliation for making Batman activate the collar, Croc badly mauled Crane's face. Scarecrow was spared any further maiming ironically thanks to Batman again, as Croc had detected his footsteps on the floating planks deeper in the sewers; he left Crane to die of his injuries, as Batman was his main target.

Scarecrow's survival.

Though terribly injured, Scarecrow managed to swim out into the Gotham river, grabbing onto a crate of the Titan Formula. Using it to float, he managed managed to sneak into Gotham and gained access to medical attention. It turned out that having his leg in Croc's grip had broken the bone in it; so he needed a leg brace. His face had been severely disfigured as well thanks to Croc, now missing some teeth and his right eye becoming blind, along with chunks of his nose gone as well.

Though Crane had no-one to blame but himself for being careless enough to venture into Killer Croc's Lair, he instead decided to blame Batman for his pain (even though Batman's intervention is what kept him from being killed). Crane decided he needed to show Gotham that their hero was nothing more than a man, by unmasking Batman on live TV and breaking the Dark Knight's will with his Fear Gas.

To this end, Crane managed to find a hideout on Bleake Island, where he set up a lab behind the storeroom of Mr. Chen's toy factory; he also gained control of the top floor of another building, where he built a gassing chamber with a two-way monitor for communications. He also brokered with The Falcone Crime Family, obtaining a boat next to their shipping yard; the hull's contents included crates Crane specifically requested be filled with insects with neuro-toxins. With these hideouts, and possibly others, Crane remained hidden from the public eye as he continued to experiment to create the ultimate Fear Toxin to break Batman once and for all.

"My toxin failed me at Arkham. Together, we will ensure it never happens again."
— Scarecrow to his test subject

As the months passed by, Crane remained hidden from Gotham, leading most of the GCPD to believe that Croc had killed him; however Batman persisted in trying to find Crane, or some evidence of where his corpse was. When Old Gotham was later converted into the super prison known as Arkham City, Crane saw a good chance to obtain an abundant amount of test subjects for his research as the Industrial District served as Joker's territory. Among the many test subjects was one of the Joker's most devoted followers, Roach; Crane could see the goon was fighting off any visible signs of fear, deciding to explain the details of his latest batch of toxin and his desire to prevent another failure like the one back at Arkham Asylum.


A hint that Scarecrow was still alive in Batman: Arkham City.

Crane appeared to have been in contact with both the Identity Thief and the Riddler, as several containers of his Fear Gas were found in the thief's hideout and in one of the rooms in which Riddler held a challenge for Batman. If true, that would explain how Crane's old mask became one of the riddles that Nygma had prepared for the Dark Knight; unless it was just a copy to remind Batman that he hadn't found Crane yet. Batman also found Crane's hideout, and Roach, who had a panic attack the moment Batman examined him. Crane was nowhere to be found, possibly having found a way to enter and leave Arkham City unknown to everyone else, as no-one but Black Mask (who used explosives) had managed to escape the prison.

Oracle was also not convinced that Crane was dead, even temporarily thinking that he managed to gas Batman and trick him into becoming the Identity Thief as the inmates all kept saying "Bruce Wayne" was responsible. The Joker appeared to know he was alive, as he suggested his Fear Toxin as being the reason Batman was hallucinating. If true, this would explain the relative ease with which Scarecrow could get a hold of victims to experiment on with his Fear Toxin, as Joker was a sadist that greatly enjoyed causing others misery; the Clown Prince of Crime cared little for his minions, and disposed of them when they weren't useful.

Batman- Arkham City - Easter Egg -14 - Scarecrow Thugs?

Batman- Arkham City - Easter Egg -14 - Scarecrow Thugs?

One of Scarecrow's dead henchmen in Arkham City during Protocol 10.

Further, it appeared that Crane had his own agents in Arkham City; during Protocol 10, many dead prisoners in orange skeleton/scarecrow outfits could be found. It's possible they worked for the other villains' crews undercover, just like the Riddler's, or had simply kept out of trouble and gathered information for Crane.

Crane later sent three hidden radio frequencies on the Cryptographic Sequencer to Batman. Each was a numeric code which, once translated, read: "I will return Batman!" "You will pay for what you have done to me!" and "Fear will tear Gotham to shreds!" Following the closing of Arkham City, Scarecrow listened in about the explosion at Arkham, which many mistakenly believed claimed Batman's life, commenting on how stupid the police are, as guns do not scare criminals and even empower the weaker thugs. He continued to play the message over and over, hoping Batman would learn of his impending return.

Before Arkham Knight Incident

"Penguin had better be careful about what he looks for. He just might find it."
— Scarecrow, as he experiments on the Abramovici twins

Penguin later employed Mr. Hammer and Sickle to track down Scarecrow, wanting him to join his group to bring order back to Gotham. Possibly leaking information deliberately, Crane managed to lure them into his hideout in Chinatown, where they found a scarecrow dressed like Batman strung to the ceiling. Sickle made the poor choice of smashing the bottles in Crane's Lab, sending both brothers into a hallucination of their father attempting to kill them. Crane tortured them for days, perhaps using their strong wills and bodies to test how lethal his toxin had become. He ended up sewing them back together, a wish the twins had, and stuffing straw into Sickle's mouth; he sent them back to Penguin with a message.

Needing better resources for his research, Crane entered a partnership with Simon Stagg. After months of extensive research, Crane ended up creating a strain of Fear Toxin that could be absorbed through the skin, effectively making gas masks useless; though hazmat suits would be effective. Another project of theirs was the Cloudburst, a device that could spread the Fear Toxin as a giant cloud, while amplifying its potency; the Nimbus Cell powering it would effectively double as an EMP, disabling any electronics not powered by the cell. Secretly, Stagg sought to reverse-engineer the Fear Toxin to cure depression; he was annoyed with Crane's obsession with revenge against Batman, willing to take the formula by force if needed.

With two years worth of time spent mostly by himself, Crane's mind began deteriorating at a much greater pace. With his hatred of Batman fueling him, Scarecrow became a near-inversion of his former self, a cackling mad scientist dedicated to studying the effects of his research; he had now become more somber, though still dedicated to his study of fear. He had come to believe that fear was the very motivation for everything, even for Batman. Crane planned to cover the entire Eastern Coast of America in his Fear Toxin, turning it into "his domain"; in other words, Scarecrow wanted nothing more than to create complete and utter chaos. If Scarecrow wasn't stopped, eventually, the entire world would fall victim to his Fear Toxin and civilization would collapse.

At some point, Crane underwent facial reconstruction surgery. The end result was his face became more hideous than it already was, resembling his iconic mask with threads linking his jaw to what remained of his upper lips and two gas mask tubes attached to his jaw. Many who saw him found it hard to keep their lunches down; others wondered if he had deliberately taken a knife to his face and cut chunks of it out. Other believed he was simply wearing a mask, due to the quality of the surgery.

It started with the meeting. Everyone was there. Penguin, Two-Face, Riddler, even poor Harley. Scarecrow said he had a plan; that together, we could take you out and Gotham would be ours.
Over my dead body.
I believe that was the intention.
— Poison Ivy explains Scarecrow's plan to Batman

By this time, Scarecrow had established his main base on Arkham Island, after TYGER was disbanded following the attempt of Protocol 10. He was found by the Arkham Knight, who sought him out because he was the only foe Batman had faced that could attack him psychologically (aside for the Mad Hatter, who is hard to stand being around, let alone talk to); Scarecrow agreed to work with the Knight to break Batman and unmask him, though he explained that once Batman was broken, killing him would be an act of mercy.

Scarecrow's men

Scarecrow with the Arkham Knight and the Miltiia.

To this end, Scarecrow called the remaining super criminals together; he met with Riddler privately, appealing to his ego, and coaxed him into launching his own challenge to Batman on Halloween as multiple threats would stretch the Dark Knight thin. Believing that Poison Ivy could further strengthen his Fear Toxin, Scarecrow tasked Harley Quinn and Penguin with freeing her from the Bludhaven Police Department.

With Ivy rescued, Scarecrow explained the plan to her, Harley, Two-Face and Penguin; they would force a mass evacuation of Gotham, leaving it to their gangs and the Arkham Knight's Militia, thus outnumbering Batman and the GCPD. Ivy flatly refused, starting that she wasn't interest in his "petty human games"; thus Scarecrow knocked her out and sent Ivy to the gas chamber in his safe house in Chinatown. This way he could test the toxin on Ivy, while ensuring she couldn't use pheromones to brainwash the militia guarding her. To cover the cost of the Militia's equipment, Crane, Harley, Two-Face, and Penguin paid a combined $3,000,000,000 to the Knight. They also hired Deathstroke as a back-up commander and adviser to the militia as he was the toughest foe Batman ever faced; they paid in advance, ensuring the mercenary's help.

The Knight also revealed a crucial piece of information to Scarecrow; Barbara Gordon was one of the Batman's allies. If they kidnapped her, this would break Batman's alliance with her father, leaving the Commissioner more vulnerable and reckless. Scarecrow favored the idea as it played on fear.

Arkham Knight Incident

This demonstration used just five ounces of my latest toxin. Tomorrow this will seem like child's play. Gotham, this is your only warning: abandon this city, or I will unleash your greatest fears.
— Scarecrow's broadcast

Gotham Abandoned

Scarecrow (Arkham Knight)

Scarecrow broadcasting his warning to Gotham.

On October 30th, Scarecrow and his army initiated their plan. The Knight went to Pauli's Diner, with a bag of the Fear Toxin to make a public demonstration of its new potency; the patrons exposed to the gas tore at each other, with Officer Owens being the sole survivor. Scarecrow then publicly broadcast to all of Gotham, and explained that horrific scene was caused by just five ounces of Fear Toxin. He followed up with the threat to detonate bombs that contained the Fear Toxin around Gotham, which prompted a mass evacuation. Many of the criminals believed that Scarecrow must have a sense of humor as he chose Halloween for his attack.

However, only Batman and the outmatched GCPD were left to face Gotham's Most Wanted - who were under Scarecrow's "protection" - as well as the Knight's Soldiers and Drones. The militia used Founders' Island as their main base. Scarecrow spent most of his time here, broadcasting to the monitors in Gotham; this reminded some of the crooks of when Hugo Strange did the same thing back in Arkham City. Most of the criminals got tired of his lectures, wishing he would at least crack a joke or something. Ominously, Crane announced that soon all of Gotham would be receiving a gift from him; he would release his toxin upon the city, allowing those infected with it to become the dark beasts that they truly were inside.

Believing they would need reinforcements, Scarecrow reached out to Mr. Freeze; in exchange for helping them, the militia would provide better resources to find a cure for Nora. However, Freeze had taken the advice Batman gave him in Arkham City to heart; he was staying away from crime and focusing on curing Nora. Annoyed, Crane had the militia attack Freeze's ship, The Nora, taking Nora's cryo pod and damaging the reactor for her cure. Scarecrow promised Victor that Nora would be returned in exchange for Batman.

Batman at Scarecrow's Safehouse in Chinatown.

Batman attacked Scarecrow's Chinatown safehouse, hoping to find him. Instead, all he found was militia troops guarding Ivy, who was locked inside the gas chamber, strapped to a chair, with a guard discouraging escape attempts. After Batman took out the guards, the one next to Ivy radios Scarecrow, who appears on the screen in the back of the gas chamber. Crane explains that he is sorry to disappoint Batman with not being able to be there in person, but he will instead give a demonstration of what was to come later than night; he gassed the room, infecting the guard, who was promptly knocked out by Ivy. The toxin had no effect on her, since she had analyzed the toxin and made an antidote for it from plant spores. Ivy proceeded to explain Scarecrow's plan, while he sent militia drones to attack her and Batman; the attempt failed.

Why do you hate him so much?
You could never understand.
Have no fear. Tonight will be his last.
I'll make sure of it
— Scarecrow tries understanding the Knight

With the militias help, Scarecrow seized control of Ace Chemicals where he set out to the Central Mixing Chamber, to mass produce the Fear Toxin to create a bomb powerful enough to take out the entire Eastern Seaboard. The Arkham Knight was to give final warning of when the explosion would go off, but Crane didn't care if there were still any troops around; infecting others with his Fear Toxin was all that mattered to him. When Batman and the GCPD arrived on site, the Knight destroyed the bridge to the facility with his attack chopper. Though the Arkham Knight wanted to kill Batman on sight (and thus make all of their planning moot), Scarecrow overrode his vehicle's systems, stated that if he killed Batman, he'd have nothing left to fear, and ordered him keep Batman away from Ace Chemicals until his work was complete.

After Batman evacuated the two surviving Ace Chemicals workers from the site, he confronted Scarecrow in the Central Mixing Chamber. Maintaining his composure, Crane knelt down with both of his hands behind his head, and showed no resistance. However, Batman smashed his head against the control panel, and demanded to know how the Fear Toxin could be stopped. Confident, Crane explained that it's impossible to stop, and that the building would soon explode and release his Fear Toxin. Scarecrow then warned the Dark Knight to release him, claiming that Barbara Gordon would be killed if he didn't comply. Batman distracted himself to contact the Clock Tower, at which point Oracle was abducted. Scarecrow escaped, and locked Batman in; departing, he taunted Batman by telling him that nothing hurts more than the death of someone closest to you.

Scarecrow left Batman to perish in the explosion that would consume Ace Chemicals, departing in a Militia helicopter to watch his Fear Toxin cover Gotham. However, Batman managed to put enough neutralizing agents in the mix to reduce the blast radius to just the area around the factory before the building collapsed. Having seen that his main plan had failed, Scarecrow realized that Batman must have escaped his trap, and would resume hunting for him. Crane realized that he would have to resort to the more time-consuming Plan B.

Attempting Break Batman

Did you think you stopped me at ACE chemicals, Batman? You have only delayed the inevitable.
— Scarecrow, rightfully confident that Gotham will face it's darkest fears

After Ace Chemicals, Crane returned to the Militia's HQ, where he would keep tabs on Batman's progress with fighting Gotham's Most Wanted. Scarecrow continued taunting Batman via the monitors, insisting that everything that happened to Batman's allies was the Dark Knight's own fault, and that his efforts over the years were pointless. At one point, he wondered if Batman had thought he was dead before this Halloween night, due to his near-death experience back at the Asylum. Noting that Batman used fear to control thugs, Scarecrow declared that he has usurped the "the throne" the Dark Knight ruled from; Scarecrow saw himself as "the sovereign" now.

Under the threat of death from the Arkham Knight, Scarecrow was forbidden from harming Barbara Gordon or injecting his Fear Toxin into her; unknown to him, the Knight was actually an old friend of Barbara's that still had a soft spot for her despite his hatred of Batman - Jason Todd.

Scarecrow had the militia harpoon Stagg's Airships and pull them back to Founders' Island, needing the Cloudburst for his Plan B. He had the Knight lock the unsuspecting Stagg in an experimentation cell as punishment for double-crossing him. Crane then went to prep the Cloudburst, ordering the militia to begin supplying power to it as knew Batman would catch wind of this. At the time, Batman had found the holding cells containing the victims of Crane's experiments, and was interrogating Stagg about his whereabouts. When Stagg began talking about the Cloudburst, Crane gassed him remotely to keep Stagg silent.

Scarecrow soon found no Nimbus Cells were being sent to charge the Cloudburst, meaning Batman had taken out his guards; he awaited the Dark Knight's entrance. Batman found him, but Crane was able to gas him with Fear Toxin; unbeknownst to Scarecrow, he was only able to do this because Batman was seeing hallucinations of the Joker, and had picked one disguised as him by accident.

You're not dying, it just feels like you are. My toxin is filling your lungs, and drowning you in your deepest fears. Soon I will tear that mask from your face and show the world who you really are; a legend layed bare. After tonight, there will be no more hope, no more legend. No more Batman
— Scarecrow, taunting Batman

"There is no more Savior. No more hope. No more Batman."

Batman writhed in agony on the ground, trying to fight off the effects of Crane's Fear Toxin. Crane paced around, taunting Batman, explaining that he would soon remove the Dark Knight's mask and show the world that he was nothing more than a man forced to face his fears. Once this happened, the people of Gotham would no longer have a savior to give them hope as there would be no more Batman. Taking Scarecrow by surprise, Batman said he has already disappeared; tossed aside, an astonished Crane decided to watch this new reaction in Batman play out. What Scarecrow didn't know was that the consciousness of the Joker had surfaced in the Dark Knight and was ready to take his body for a test drive.

The possessed Batman pummeled the militia soldiers that came to backup Scarecrow within an inch of their lives, as the mad doctor watched. As the effects faded, Batman regained control of his body, and Crane remarked something about him seemed different he was showing fear. When warned by Batman that there was nowhere to run, Crane back up to the wall and laughed "Who said anything about running?" Holding onto the ladder, Scarecrow and the Cloudburst were pulled away from the airship by a helicopter. When Batman attempted to follow him, Scarecrow had the Knight run interference by launching rockets at him.

Once safely away from Batman back at the Militia HQ, Scarecrow broadcasted a message to all of Gotham, demanding Batman's attention. As part of his twisted mind games, Scarecrow has placed Barbara in his gassing chamber back in Chinatown. Batman arrived, Scarecrow doused him with Fear Toxin; Barbara was kept unaffected due to being in the gassing chamber. In Batman's mind, Barbara had been gassed and was freaking out at the sight of him. Seeing this, Scarecrow decided to take advantage of the Dark Knight's fear and "instructed" Barbara to pick up a gun and "deny him". To Batman, Barbara futilely shot at the glass, ultimately committing suicide via gunshot to keep herself from being attacked by the monster she saw in Batman's place; this even fooled made Batman misread the information in Detective Mode.

Little did Crane know, this "punishment" almost made Batman consider just letting the Joker's influence take over to rid himself of his pain. Once Batman left, Scarecrow waited until the gas in the room faded before sending in the Militia to collect Barbara from the gassing chamber.

Batman, what happened back there wasn't cruelty. It was necessary.
— Scarecrow defends his actions

Crane kept the fact that Barbara was still alive a secret, hoping to push the Dark Knight further and further, until his facade broke and everyone saw the fraud he truly was. He contacted Batman through the monitors again, asking what it was like to see the hallucination react to seeing "his true self" - whatever kind of monster the fear gas would make Batman look like; he defended this action, calling it necessary, not cruelty. As Batman never responded to him, Scarecrow began wondering aloud if the Dark Knight's mask helped push down any actual emotion that he should be feeling.

Unknown to Scarecrow, Batman had the Batwing circling the three islands of main Gotham to find the Cloudburst, which gave off a unique energy signature; at the time, more Nimbus Cells were being loaded into the device, leaving it vulnerable to being destroyed.

As two enormous plants had erupted out of the ground on Miagani island, Scarecrow released an unlikely alliance had be struck between Batman and Ivy; the two were working together to revive plants with pollen able to neutralize the effects of this new strain of Fear Toxin. Crane broadcast to Gotham again, telling Batman it was a wasted effort; Ivy would also be paying a steep price for defying him. Scarecrow sent the militia's drones to kill the plants, hoping to find the one Ivy was hiding in; with her dead, nothing would be able to hinder his efforts to unleash terror upon Gotham. However, they were destroyed by the combined efforts of Ivy manipulating the roots and the Batmobile's weapons.

Seeing no other way to accomplish his plans, Scarecrow finished powering the Cloudburst and had it attached to the Knight's personal tank, sending him to Bleake Island to activate Plan B. Seen from all around Gotham, a large blast of fear toxin was launched from the machine, high into the sky; it exploded, releasing an electrified fear cloud that swallowed Miagani, Bleake, and Founders' islands. The rest of Gotham was left untouched by the release of the fear cloud, allowing those still unaffected to see the horror.

The City of Fear

Welcome to Gotham... the City of Fear
— Scarecrow, bragging about the success of his plan
BATMAN™ ARKHAM KNIGHT 20150625113607

Scarecrow's plan succeeding.

Within the confines of the infected area, all the rioters had begun attacking each other in terror; each was seeing whatever it was that they feared most in place of their fellow criminals. Gotham was left glowing orange from the fear cloud, which was sustained by the Cloudburst. As a side-effect of using the Cloudburst, the Batmobile was left inoperable as it did not run on a Nimbus Cell.

Once the blast had subsided, Scarecrow broadcasted to Gotham again, stating that it had been transformed into his City of Fear. Having been exposed to his toxins, the inhabitants of Gotham have now seen Batman wasn't unstoppable and had finally failed them. The Cloudburst also had the effects of amplifying the toxin to the point were it was leeching the life from the plant-life in Gotham. To keep the plants from dying, Ivy connected herself to them, feeding them her own life energy to keep them alive. Aware of this, Scarecrow broadcasted again, telling Batman that while his toxin attacks the human mind, it's killing Ivy.

Batman proceeded back to Stagg's Airship, where he knocked out the militia guarding the hole left by the theft of the Cloudburst. Stagg had escaped from his cell, forcing Scarecrow to order the other half to the group to find and silence him, to keep any remaining information about the Cloudburst secret. Batman knocked them out and confined Stagg in one of his own specimen cages; he proceeded to take a Nimbus Cell, to re-power the Batmobile. Batman braved the fear toxin cloud, refitting the Batmobile with the Cell, and went to help release third plant to clear the toxin. Once the plant was out, Batman headed off to destroy the Cloudburst.

When Bleake Island's bridges were raised remotely, Scarecrow ordered the Knight to retreat; however, the Knight ignored him, deciding to kill Batman. Batman took out the drones escorting the Knight's tank, one-by-one; each time, Scarecrow ordered the Knight to make a strategic retreat. However, much to his anger, Scarecrow was ignored; he even pointed out that the Clouburst was HIS property, not bait. Unfortunately, the Dark Knight scanned the tank, learning of the cooling systems that kept the Cloudburst from exploding. He attacked them and the main body of the tank, leaving the Knight without any means of escape.

Scarecrow continued watching these events, seeing Batman drag the Knight out of his tank and onto a rooftop. The Knight attempted to choke Batman, who pinned him and proceeded to pummel him. However, Batman began hallucinating again, allowing the Knight to flee. Scarecrow told the waiting Deathstroke that he had his chance to go after Batman, letting him use the majority of the militia however he pleased. Without the Cloudburst to maintain it, the Fear Toxin cloud was cleared away by Ivy; however, the strain of doing so cost Ivy her life. Comforted by Batman, she dissolved into dust and blew away in the wind.

Abandoning the Arkham Knight

How many more bones will you crush? How many more lives will you destroy in pursuit of what you call justice? We are all products of what we fear. I look at you and see a man born of violence and darkness.
— Scarecrow, explaining his observation of Batman

The rogues were left enraged that Scarecrow had subjected them to such horrors. Crane was then left to rethink his plans, deciding to again focus on unmasking and breaking Batman. He broadcast to Gotham, explaining the militia now obeys him, and that while his Fear Toxin was cleared away, he had succeeded in breaking the faith Gotham had placed in Batman; the Dark Knight was not as omnipotent as everyone had thought he was. Adding onto this was the long time the city would need to recover from the attack.

Crane soon captures Gordon, who had tracked him down to rescue Barbara. The deranged Master of Fear offered the overprotective father a deal; he would release Barbara, in exchange for bringing Batman to him. Though disappointed with the Arkham Knight, Crane allows him to use Gordon as bait to lure Batman to his secret HQ. This leads to the successful destruction of the Batmobile, by the Knight's giant excavator. The fight between the two leads into the HQ, where the Knight reveals himself to be Jason Todd, Robin 2; having been tortured by the Joker for over a year in an abandoned wing of Arkham Asylum, and then abandoned, Jason had focused all his pain into a monomaniac hatred of Batman, who he blamed for his ordeal. After Batman shows kindness to him, the Knight vanishes into the city, leaving Scarecrow in charge of the remaining forces.

Do you know what happens to a man who refuses to be controlled by his fears? He must face them!
— Scarecrow, threatening Gordon

Per the agreement struck between them, Gordon lead Batman to an elevator leading them to the roof on a building under construction. Meeting together, Crane reveals Oracle is alive and the pact he made with Gordon, ordering him to carry out his end of the deal by threatening to push Barbara off the building. Gordon intentionally shot Batman in the chest (where he knew that Batman's armor was the strongest) and Batman fell off the building. But Scarecrow, who didn't want Batman dead, pushed Oracle off the building where Batman caught her mid-air. Though Barbara was safe, Crane made his leave with the Militia and Gordon as his hostage by helicopter. He sent drones to check and see if Batman lived; not only was the Dark Knight still alive, he had a second Batmobile, which reduced the drones to scrap metal.

Forcing a Final Confrontation

After Batman returned Barbara to the GCPD Lockup, Scarecrow send drones to assault the GCPD using this as a distraction, Crane used Gordon to access Panessa Studios. He likely learned about the victims of Joker's blood and wanted to see if he could use them in his research. Instead, he found their corpses and both Robin and Harley locked up in cells. Though Robin attempted to attack them, once released from his cell, the militia succeed in subduing him and breaking his bo staff. Scarecrow then had his mark painted on the cell, as a calling card to Batman, hoping that with two hostages, he had twice the control over Batman's fears. However, he also refused to release Harley, who held no further purpose in his plans. Batman later returns and sees the scene, being informed by Harley about what happened and of where the next message from Scarecrow would come from. Appearing on a monitor at storage depot in Kingston, Crane informed Batman that if he wanted to save Robin and Gordon, he had to surrender himself to him. Batman accepted, turned himself over to Scarecrow, and abandoned his utility belt. Batman then entered a van and was driven to Arkham Island, where Scarecrow was waiting for him. After he arrived at the Arkham Mansion at the abandoned Arkham Asylum, Batman found Gordon and Robin being held captive by Scarecrow.

Batman Unmasked

Now the world can see you for what you truly are. A legend laid bare. Powerless. Human. Afraid.
— Scarecrow, unmasking Batman

Scarecrow revealed he was broadcasting live across the city, seeking to make Gordon unmask Batman so that Gotham could see their beloved hero's face as he succumbed to the Fear Toxin. Initially, Gordon protested, so Scarecrow shot Robin in the chest. Robin lived due to his suit's armor, but Scarecrow threatened to shoot him in the head if Gordon didn't cooperate. Batman told Gordon it was the only way and the Commissioner reluctantly unmasked him; upon Batman's unmasking, the televisions showing the broadcast and its reaction were full of shock as the Dark Knight was revealed to be Bruce Wayne.

Scarecrow was surprised to see that his old foe was a supposed billionaire playboy. He then explained he wouldn't kill Bruce, but instead "set him free" to watch as Gotham fall apart at the shock of learning Batman's true identity, and to watch thugs attack his allies to get revenge for all that Batman has done to them. Scarecrow then proceeded to inject Bruce with his fear toxin, hoping to expose him as a fraud. He then watched as Batman began writhing in agony as the toxin began taking hold on his mind.

Moments later, he gloated that soon Bruce's life would be over. To his shock, Crane heard Batman say it was a good thing. Baffled, Scarecrow asked if Batman could understand it's over. Batman told him to get ready for the encore, laughing madly. Wondering "why aren't you scared?", Crane injected Batman with another dose of the Fear Toxin. Unbeknownst to Scarecrow, he was actually speaking to the Joker, who had managed to gain control of Batman's body. However, this extra dose of the toxin was just was what Batman needed to show Joker his own fear of being forgotten, and eradicate his prescence in his mind.

To Scarecrow's shock, Batman flatly told him he wasn't scared. Annoyed, Crane gave him another dose of the Fear Toxin. However, Batman continued to fight off the effects. Declaring that life is meaningless without fear, Scarecrow pulled out his gun, pointing it as Batman's head. However, it was shot out of his hand by the Red Hood, who sided with Batman once more. Scarecrow ready another injection, hoping to kill Batman with a stabbing to the head. However, Red Hood's next shot freed Batman's arms.

Grabbed by the Dark Knight, Scarecrow was given a dose of his own medicine, despite his protests. Feeling the effects of the toxin, Scarecrow tried fighting off the visions it gave him. However, upon hearing Batman ask if he was scared, Crane let go of all restraint, yelling in fear; he saw Batman as a demonic bat figure, commanding a swarm of bats. Trying to flee, Crane was knocked out by Gordon.

Crane was then taken to the GCPD Lockup in the Batwing. Reduced to a mumbling, cowardly former shell of his self, Crane was locked in the maximum security cell along with the rest of the other super criminals. Crane spent the entire night, sitting cross-legged, holding his head in fear, and scanning the cell. Seeing that "the lights were on, but nobody was home", none of the other super criminals made an effort to talk to Scarecrow.

Without fear, life is meaningless
— Scarecrow's belief
Scarecrow underwent an extreme personality change between Arkham Asylum and Arkham Knight, that was presumably due to being driven into a bitter traumatization after his near-death experience with Killer Croc.
Scarecrow nightmare defeat

Scarecrow Nightmare.

In Arkham Asylum, Scarecrow closely followed his over-the-top comic book portrayal: a downright, sadistic villain who took glee in murdering innocent people and/or driving them into insanity, complete with a high-pitched voice with a loud and dramatic tone to it. As evidenced by his Interview Tapes, Scarecrow was extremely intelligent and manipulative, as he managed to convince one of the asylum doctors that he wasn't insane. Scarecrow did the same to Dr. Young, who even believed that he was innocent. Scarecrow treated the concept of fear like a religion, said that almost every action you did was solely because of fear, and proved his megalomania by wanting to control fear and use it to gain power. This is further shown in Arkham Knight where after detonating the Cloudburst, drowning Gotham in his toxin he proudly describes it the "city of fear" and "my domain."

In Arkham Knight, two years after Arkham Asylum, Scarecrow was almost a complete inversion of his former self. He possessed an incredibly calm and deep voice, and spoke in a soft-spoken monotone. While he was a giggling psychopath in Asylum, Scarecrow was an emotionless mastermind who only laughed twice. He still retained his sadism, his unmatchable brilliance, his religious dedication to fear, and proved himself to be a omnicidal maniac, as he planned to cover the entire Earth in Fear Toxin starting with the Eastern Seaboard.

His bio also mentioned that after years of forcefully being injected with it thanks to Batman, Scarecrow was utterly immune to not only his own Fear Toxin, but fear itself, as not a single concept could arouse him into a fearful state, except bats. That fear may be natural, but could also be caused thanks to Batman. Even when being face-to-face to a wildly angered Batman, Detective Mode proved that Scarecrow was still calm. Scarecrow's only examples of emotion was temporary fury when the Cloudburst was destroyed, and when he was permanently reduced into a terrified, mumbling mess after a colossal dosage of his own Fear Toxin that was injected into him by Batman at the Arkham Mansion.

Scarecrow's psyche was fractured so much after Arkham Asylum, that he didn't care about Batman's true identity as long as he got to destroy him and show the world who was really behind the cowl. Scarecrow's obsession with fear became even more warped, which lead him to desire to coat the world in his Fear Toxin to destroy millions of minds.

Whereas in Arkham Asylum he treated fear as a religion which governs every actions of every day, given Arkham Knight he has begun to see it as a fundamental factor of life and without it, life itself would be meaningless. This can be attributed to his obsession with laying bare the legend of Batman, proving to the world that he was just a man and nothing more, as witnessing a man who was by all means fearless was an insult, almost blasphemy to Scarecrow's views of life, a prospect of his fear-religious ideals. As a person, who was essentially a man of fear he understood that hope was the catalyst of terror, and has shown multiple times to be against its concepts. As Batman was the embodiment of hope in Gotham by unmasking him Scarecrow would equivalently be taking all which he stood for, placing Gotham in a (literal) reign of fear without his protection.


Batman: Arkham Asylum

BAA Scarecrow1 cutout by Crank

Scarecrow: Arkham Asylum.

Like most villains in the series, Scarecrow's appearance changed depending on setting, materials and even his psychological condition. The basis for Scarecrow's costume may have been similar to his mainstream DC Comics counterpart, referencing the Headless Horseman trick from Sleepy Hollow and the Scarecrow from The Wizard of Oz, inspired by his love of reading, and a rather on the nose symbol for the role that he wished to play in his victim's terror. Before the events of Arkham Asylum, Scarecrow used a costume that was slightly similar to his comic appearance, which incorporated an actual scarecrow-like appearance with a burlap mask that showed his eyes and mouth, and was topped off with a hat and a cloak.

After he was captured and released, Crane may have had to scavenge for materials to complete the costume that was seen in the game. Scarecrow was shirtless, and his trousers, cowl, and sleeves appeared to be woven together from various rags, possibly from an Arkham inmate uniform. His mask had been altered into a cowl with the aesthetics of a hood and a noose, and acted as a gas mask. Scarecrow wore a brace over his right hand with syringes that extended over his fingers, which allowed him to simultaneously attack and inject a victim with Fear Toxin if they didn't breath in his gas. Scarecrow was often seen hunched over so that his skin was hardly visible and looked more like a scarecrow.

Batman: Arkham Knight

Scarecrow (Arkham Knight)

Scarecrow: Arkham Knight.

Scarecrow's appearance was vastly different due to the injuries that he had sustained at the hands of Killer Croc. Scarecrow may have been blind in one eye and his face seemed to be damaged: it was no longer clear how much of his face was a mask or scar tissue. His right leg may have been permanently broken as it was secured in a leg brace. Even with his broken leg, Scarecrow now stood much taller than in Arkham Asylum due to not hunching over.

Crane's new gas mask also appeared to be surgically grafted to his throat, as it didn't cover his mouth or nose. It was mentioned by random Militia chatter that after Killer Croc's attack on him at Arkham Asylum, Crane underwent surgery to make his face appear as it did in Arkham Knight: he surgically grafted the mask to his face.

Crane may have sustained damage to his windpipe that necessitated a respiratory bypass, which explained why his voice was so much more gravelly than before. Another piece of evidence to support that theory was the presence of two tubes going into the underside of Crane's lower jaw, with one of them being attached to one of his Fear Toxin canisters.

Another possibility was that Scarecrow's voice in Arkham Asylum may have not been his real voice and he altered it to make it more scary. Whether or not Crane took micro doses of his own Fear Toxin to make himself immune to it was unknown.

To better wage his war, Scarecrow wore a trench coat that was modified to hold multiple vials of Fear Toxin, which provided him with a larger supply. Scarecrow's fingertip syringes were upgraded to include claws that were latched to his wrist for combat. Altogether, Scarecrow resembled an undead being.

Psychological Profile

Dr. Penelope Young


Real Name: Dr. Jonathan Crane

Possibly one of my greatest successes here at the asylum. Despite his tendency for extensive role-play (oddly common among Gotham City's criminals), it's unclear to me why Dr. Crane was ever considered insane. In our long discussions, I've been impressed with his genius for psychology and biochemistry, and I fully believe that if presented with a stock of his fear-inducing gas, he would feel no compulsion to use it. He seems to have entirely turned away from his former life of crime as the Scarecrow.

Additional Notes

He's valiantly battled a history of anxiety disorder, due to a difficult childhood and adulthood trauma, through an intense study of psychology and the causes of fear.

I've come to believe that the accusations that he experimented on human subjects are wildly exaggerated.

GENIUS at Chemistry!

Would he have something to contribute to 'Titan' research?


  • Master of Fear.
  • Expert psychiatrist with a specialty in anxiety disorders and psychoactive drugs.
  • Employs a fear-inducing toxin that creates nightmarish hallucinations.
  • Obsessed with creating fear in others
  • Master Scientist with a genius level of expertise in biochemistry.
  • Master Strategist with a frightful level of skill in psychological warfare

Patient Interviews

Tape One

  • Jonathan Crane: Patient Interview 1. Patient was referred to me after the incident with Dr. Murphy. He appears to have suffered a breakdown of sorts. I believe it was brought about after the loss of his wife and child. As yet, the patient has been unable to speak. Continued observation shows little mental activity. It's as if the shock of what he saw triggered his mental collapse.
  • Security Guard: There's someone in here! It's him! We've found him! Break down the door!
  • Jonathan Crane: Note to self. As ever, it is difficult to continue my research under such conditions.
  • Security Guard: Step away from Dr. Combs. Now! Get down on the ground! We've found them. Someone get a medic! Oh God, what's he done to him?

Tape Two

  • Dr. Stephen Kellerman: Patient interview 6. Dr. Crane has been back in custody for 3 weeks. Regular sessions have been inconclusive. I am not sure he is actually insane.
  • Jonathan Crane: Good evening, Stephen. How are you tonight?
  • Dr. Stephen Kellerman: I'm conducting the session, Jonathan.
  • Jonathan Crane: Of course. If that helps you cope, I wouldn't have it any other way.
  • Dr. Stephen Kellerman: Let's talk about the events 3 weeks ago. What did you think you'd achieve? Dr. Murphy is still in therapy.
  • Jonathan Crane: I wanted to understand him. His personal demons. His fears. It's all quite fascinating, really.
  • Dr. Stephen Kellerman: But you are... were a respected doctor. A brilliant mind, now just another resident in Arkham.
  • Jonathan Crane: Can I have a drink? A strong one? This kind of question bores me.
  • Dr. Stephen Kellerman: I'm afraid not.
  • Jonathan Crane: Interesting choice of words, Doctor. Tell me, what are you afraid of?

Tape Three

  • Dr. Stephen Kellerman: Patient interview 9. Dr. Crane continues to evade questions. I believe he is quite sane. Just evil. He takes no interest in the people he has hurt. His research appears to be the only motivating factor in his life. What is it about fear that drives your obsessions?
  • Jonathan Crane: Fear drives everything, Stephen. Everything. Your life is governed by fear. Every decision you make is a product of that fear.
  • Dr. Stephen Kellerman: Don't be ridiculous.
  • Jonathan Crane: You married your wife...Margaret, isn't it?...because you were scared of dying alone. You have children because you are scared of leaving nothing behind that really matters. You go to the doctors because you're scared of dying. Do I need to go on?
  • Dr. Stephen Kellerman: No. I think that will be all for today. Guards!

Tape Four

  • Dr. Stephen Kellerman: Today I have another interview with Crane. I cannot say I am looking forward to it. I've been feeling anxious. I don't like to admit it, but...I think he's getting to me.
  • Jonathan Crane: How are you today?
  • Dr. Stephen Kellerman: I keep telling you, this is my session.
  • Jonathan Crane: It was your session, Doctor, but not anymore.
  • Security Guard: Are you OK, doc?
  • Dr. Stephen Kellerman: I think...yes..I...
  • Jonathan Crane: Oh, he's fine. Just questioning his grip on reality. You should be doing the same any second...
  • Security Guard: Mom, is that you? Wait, what are you doing?
  • Dr. Stephen Kellerman: Get off of me... Help. I need help here. I can't breathe...
  • Jonathan Crane: Like I said... You're all part of my experiment now!

Tape Five

  • Jonathan Crane: Asylum interview 1. My experiment is underway. Working alone, I have created my ultimate Fear Gas, its potency a revelation.
  • Dr. Stephen Kellerman: Ah! Ahh! They're all over me!
  • Security Guard: Please, daddy, don't do it! Ah! Ahh!
  • Dr. Stephen Kellerman: Keep away! Keep away! Keep away!
  • Jonathan Crane: I have pumped enough gas into the Medical Center to break 100 minds. It should only be a matter of time before... [Sound of glass shattering] What?
  • Batman: Give it up, now!
  • Jonathan Crane: are you still standing? How come it's not affecting you?
  • Batman: Who says it's not?
  • Jonathan Crane: I knew it. What was it like? What have you seen?
  • Batman: Officer Cash. Get this formula to the air-conditioning system. Now! You failed, Crane. Again. I've been working with Dr. Kellerman, creating an antidote to the toxins in your cologne. He fooled you, Crane. How does that make you feel? Threatened, humiliated? Scared?

  • "Are you afraid of what I will do when the Cloudburst is charged? Don't be. I have guaranteed your protection. Fear what will happen to you should you fail to charge it."
  • "Not yet. The Cloudburst must be fully charged."
  • "You're not dying, it just feels like you are. My toxin is filling your lungs, drowning you in your greatest fears."
  • "What can you see? A city engulfed in fear? Betrayed by those you trust the most? Your darkest secrets revealed?"
  • "As I tear your mind apart, Gotham will watch. I will cut that mask from your face, and the whole world will see the fear in your eyes. Then they too will understand. There is no savior. No more hope... No more Batman."
  • "What?"
  • "Astonishing. Such brutality."
  • "You almost killed these men. You were ready to abandon your beliefs, everything you stand for."
  • "You tell yourself you are not like us. You tell yourself you are something more, something better."
  • "But fear reveals the truth, erodes your self-control. Soon you will kill and become that which you hate the most. Soon, the Bat will be broken!"
  • "Something's changed. You're different!"
  • "Who said anything about running?"
  • "How does it feel to see your city on the brink of ruin, your friends in the clutches of death?"
  • "You stretched yourself too far this time, Batman, and now your failure is all but complete."
  • "As that final dying breath escapes her body, she will know you are the one who failed her."
  • "We both know fear is theatrics, Batman, so permit me the indulgence of putting on this show."
  • "Yes, you see it now. The horror behind the glass, the monster that will be your end... unless you pick up that gun and deny him."
  • "You will bring death to all who follow you."
  • "Batman, what happened at the safehouse was not some cruel game. It was necessary."
  • "Tonight is about more than Gotham. It's about what you became in that room. The hero who failed. That's what I want the world to see."
  • "Do you mourn, Batman? Or are you really the stoic caricature you play? Beneath that mask is a man, I'm sure. A man who grieves, a man who suffers. A man who fears the reckoning to come."
  • "Do you still see it, Batman? The terror in her eyes as she looked upon your true self? Savor that image. There are many like it still to come."
  • "Good. Are we still on schedule?"
  • "Your patience will be rewarded soon."
  • "Welcome to Gotham...The City of Fear."
  • "Do you see this, Batman? Your poisoned, desolate city? Its people tearing out each other's throats, their own throats, in terror? The world sees it too. Next, the world will see what happens to the man who tries to stop me. And when it does, the world will know fear. You aren't fighting for Gotham, tonight. You're fighting for every desperate fool who thinks that when their worst fears come to pass, a hero might come and save them. And you're losing."
  • "Do you see them? All the monsters you created."
  • "My toxin will fill the streets, and bring this city to it's knees. I will take from you everything you fear to lose, and I will watch you suffer. Scared yet?"
  • "What do you seek on those tunnels, Batman? Hope? You will find none."
  • "How did you persuade Poison Ivy to come rallying to the aid of a city she despises? Threats? Blackmail? Charm?"
  • "She's dying. My toxin strikes at the minds of humans, but it leeches the life from her."
  • "Dr. Isley cannot stop me. But how noble you were to make her Gotham's first line of defense."
  • "How can the world know fear-true dread-when it has you? A stalwart knight, ever ready to slay monsters. Fear isn't pure biology, Batman. It's more than instinct. True fear is the absence of hope. And hope is the spread wings of a Bat, shining on the clouds."
  • "You promised that Gotham would be safe. Protected! But what does the world see now?! My toxin choking its streets! Blotting out the moonlight! Poisoning the saplings you thought could stop me!"
  • "And now, Dark Knight, I turn to you. But don't be afraid. It's not your life that needs ending, it's your myth. The hope that you stand for. The hope that dies tonight."
  • "Don't fret. This tree won't make any difference. Ivy isn't strong enough to purify Gotham. No one is."
  • "Your escort is almost gone, Knight. Protect the Cloudburst, withdraw."
  • "What do you think you're doing?"
  • "This is not the plan we agreed upon."
  • "He's trying to overheat the cloudburst. Leave now."
  • "You will have your chance to kill him."
  • "The cloudburst is not bait, Knight. It is mine."
  • "The cloudburst won't withstand another strike. Retreat."
  • "Batman! The Cloudburst was mine! My greatest weapon! My instrument of fear! I will exact vengeance for this on you and all your allies. Like Poison Ivy. My toxin overwhelms her. She's paying the price for opposing me right now."
  • "You actually believe you've won, don't you, Batman? Savor this fleeting delusion of victory."
  • "The Arkham Knight may have fled in terror, but now his army answers to ME!"
  • "For even as my toxin dissipates, it leaves behind a forsaken city, forever tainted by your failure."
  • "Tonight, the myth of Batman dies and Gotham dies with it."
  • "Batman has arrived ahead of schedule. Lock down the elevators and find him."
  • "Do you still believe that you are Gotham's savior? Soon, the world will see you for what you truly are: a fallacy, a figment of hope in a world of suffering and pain."
  • "How many more bones will you crush? How many lives will you destroy in the pursuit of your crude justice? We are all products of our fears: I look at you and see a man born of violence and darkness."
  • "What will you give to save your friends, I wonder? Are you ready to reveal your secret? Are ready for your legend to die?"
  • "The commissioner placed his trust in you, to keep his city safe, his family safe. Can you still atone for your failure? Are you still the master of your own destiny? The answers are waiting, Batman, as am I."
  • "Stop this, Knight. Everything is in hand."
  • "We had a plan. He is going to suffer."
  • "So you did it. I must admit, I had my doubts that you could make this happen."
  • "And I'm not talking to you. It is time." (Gordon)
  • "Call in the transport. We're leaving." (Militia Soldier)
  • "It is time for the people of Gotham to see their savior for who he truly is. A man. Just a man. Devoid of hope, betrayed by his friends, crippled by fear."
  • "You both still have a part to play." (Gordon)
  • "Once I understood your greatest fear, controlling you was simple. You blame yourself for her condition."
  • "You need to protect her, but buried deep down is the inevitability that you will one day fail."
  • "And that fear makes you mine."
  • "Think very carefully about your next move, Commissioner. Her life depends on it."
  • "Did you think I wanted him dead? Did you think that would save your daughter?" (Gordon)
  • "Do you know what happens when a man refuses to be controlled by his fears?" (Gordon)
  • "He must face them!" (Gordon)
  • "Shh... It's OK to be afraid." (Oracle)
  • "Do not listen to Batman's false orders. The Knight is gone. You answer to me and me alone." (To the militia at the clock tower after using the voice synthesizer too much)
  • "Do you take pride in what you have reduced them to? The mewling babes your assaults exposed? I will do that to you, Dark Knight. I will peel back every layer of the Batman before the night is through."
  • "Gallant police force of Gotham. I have a message for you. You are not safe. You are not protected. Batman will not save you. This is the beginning for the end for you, Dark Knight."
  • "GCPD- The home of Gotham's brave men and women, a beacon for hope in a city of chaos and despair. Watch as I obliterate it, and the lives of all that cower within its walls!"
  • "Remove them."
  • "Barbara Gordon."
  • "You cannot sustain their hope any longer, Batman. They will die afraid and forsaken. Reflect on your failure as you salvage their corpses from the rubble."
  • "You cannot stop it, Batman. Their world is crumbling."
  • "Nothing's changed, sergeant. Reduce that edifice to dust and this battle is ours."
  • "The ones that fight at your side still believe in you. I will show them how misplaced that belief is."
  • "It's time. Send them in."
  • "You played your part. Now Batman will play his."
  • "Looking for someone? You should know by now that nowhere is safe. The Commissioner was so eager to betray you earlier, when his daughter's life depended on it. And now, I have your Robin, the caged bird. Fascinating that your fears would drive you to lock your closest ally in a prison cell. Now those same fears will make you do as I say. There's a storage depot in Kingston. Go there, alone. Prepare to take off that mask. Or your friends will die."
  • "Your fears got the better of you I see. How fitting that I will win and Batman's life will be over... not because of what I have done to your precious city, but because you are scared of what I will do to your friends, your family. They are your weakness, hiding just below the surface. I'm sure that you're scared of what will happen when I tear that mask from your face. What will we find? Your true identity, or proof that without your mask you are nothing. Impotent. Powerless, Afraid. Leave your equipment on that table, and we can find out."
  • "Now, the truck."
  • "The die is cast, Batman, and from now on I need your undivided attention. The nightmare is almost over, your failure almost complete. I can see it, and soon the whole world will see it too. Your eyes betray you. You are truly afraid."
  • "Are you ready?" (Batman)
  • "Enough bravado. It's too late for that. I don't care who you are, but they will. I'm going to rob them of hope. As they stare into your eyes they will blame you...Failure will have a face and a name."
  • "It's time."
  • "Mister Gordon, I would like you to do the honors." (Gordon)
  • "Take off that mask or my next shot will kill him. NOW!" (Gordon)
  • "Wayne? Bruce Wayne?"
  • "Now the world can see you for what you truly are. A legend laid bare. Powerless. Human. Afraid."
  • "Do you know what happens now, Mr. Wayne? I'm not going to kill you... I'm going to set you free... Free to see the city you swore to defend tear itself apart. Free to see everyone you love hunted down and killed. Every scream, every death, vengeance for all that Batman has done."
  • "What? Do you not understand? It is over." (Joker is in control of Batman)
  • "Why-aren't-you-scared?"
  • "Do you understand, Gotham?"
  • "You have no savior."
  • "No more hope... No- more- Batman!"
  • "I've won."
  • "Impossible..."
  • "Without fear, life is meaningless."
  • "No!" (before being injected with his own toxin by Batman)
  • "AAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHH!" (after being injected with his own toxin by Batman and facing his own fears.)

Batman: Assault on Arkham

Batman: Arkham Asylum

Batman: Arkham City

Batman: Arkham Knight


  • The Doctors Murphy and Combs that were mentioned in Scarecrow's Patient Interview Tapes referenced Cillian Murphy, who played Scarecrow in the Dark Knight Trilogy, fitting as Batman Begins and The Dark Knight, the two most recent depictions of Scarecrow at the time of Arkham Asylum's release, and Jeffery Combs, the voice of Scarecrow in the fourth season of Batman: The Animated Series.
  • Scarecrow's glove in Arkham Asylum resembled the titular bladed glove of Freddy Krueger, the fictional serial killer from the Nightmare on Elm Street films.
    • His syringe glove in Arkham Knight, however, more resembled the claws of Wolverine from Marvel, as they were retractable and only notably activated when Scarecrow made a fist.
    • Crane needing to make a specific gesture with his fingers could also be a nod to Spiderman as well; specifically, his web shooters. Spidey could only activate them with just his middle and ring fingers, so they wouldn't go off by accident if he made a fist.
  • Scarecrow was the only villain in Arkham Asylum to mention Batman as Wayne. He said his surname during the third encounter. However, as Batman was wildly hallucinating at the time, it was very unlikely that Crane himself actually knew Batman's secret identity, and in Arkham Knight, he was surprised when he found out Batman's identity. Ironically, it would be much later that Scarecrow became the one that finally unmasked Batman and revealed his identity to the world.
  • After you defeated Bane, Dr. Kellerman said that "Just after you took the elevator down, the PA was full of screaming. It was horrible." if you returned to the Patient Observation Room to speak to him.
  • Scarecrow had his own Challenge Map that was titled "Scarecrow Nightmare." Crane himself appeared in the background, similar to his in-story hallucination appearances, and taunted Batman as he fought the Fear Gas skeleton henchmen under his command. The goal was to survive for as long as possible against the never ending waves of thugs without taking a single hit, which instantly killed Batman.
  • During the final nightmare with Scarecrow, you could not skip the cutscene with Joker taking Batman to the asylum, which made it the only un-skippable scene in the game.
  • Like Joker, Scarecrow didn't have an identifiable cell at Arkham Asylum. Theoretically, he could have been held in the "Extreme Isolation" area of Arkham, which was the one place that the player could not explore.
  • In Scarecrow's Lair under the elevators, computer monitors showed security camera images of Batman escorting Joker through Arkham. Crane may have already escaped his cell prior to the riot, and had managed to observe the event. Given the number of supplies that were present, Crane may have had a way of slipping in and out of his cell without being noticed, and smuggled in the necessary items.
  • During the nightmare sections of Batman: Arkham Asylum, Batman would occasionally appear as Scarecrow, which made Scarecrow technically a playable character.
  • Crane's appearance in Arkham Asylum had been ranked as the 38th Greatest Moment in Gaming.
  • The Arkhamverse Scarecrow made a cameo in the DC game, Injustice: Gods Among Us. The game had many damaging stage transitions, one of which took place in the Arkham Asylum Stage. One player could throw another through a wall and into Crane's cell. Scarecrow would inject the player with his Fear Toxin, which triggered a voyage into Crane's nightmare world, before they were thrown into another section of the level.
  • Scarecrow is the only villain to physically appear in Arkham Asylum, who doesn't have his face revealed in game.
    • His face is revealed in Arkham Knight. Listening to criminals in Gotham reveals that he underwent facial reconstructive surgery, and isn't wearing a mask, meaning his face has been redesigned to look like his trademark mask.
  • In Arkham Asylum, Crane's skin was deathly pale and he was extremely skinny, which indicated possible anorexia. Oddly, Crane appeared much taller in Arkham Knight, which was unusual given his crippled state. It should also be noted that during Arkham Asylum, Scarecrow walked hunched over whereas in Arkham Knight, he walked normally. It's possible that the leg brace prevents him from hunching over.
  • The injuries Crane sustained from Croc, along with the underwent Surgery would explain the drastic change in his natural voice Between Arkham Asylum & Arkham Knight.
  • In his Game Over Lines for Arkham Knight, Scarecrow's voice was always distorted by his Fear Toxin. That was even when he's not actually around when Batman died.
  • A barely noticeable outlining of Scarecrow could be seen next to the Azrael symbol at the Church and Medical Center in Arkham City.
  • The "City of Terror" code that was required to unlock Crane's Barge was one of the hardest security codes to decrypt in Arkham City, because it was at level five on the Cryptographic Sequencer.
  • In the one his the phone calls to Batman in Arkham City, the Joker implied that he was aware that Scarecrow was still alive.
  • Scarecrow's Arkham Knight design resembled his incarnation in the 4th season of Batman: The Animated Series. In that season, Scarecrow resembled a legitimate undead being in a preacher's outfit. In both designs, their teeth were visible as well, though while in the former's case, it was his genuine teeth, in the latter it was left ambiguous, as the producers were uncertain if there was someone under the mask. It was revealed by Militia chatter that Scarecrow underwent surgery after he was attacked by Killer Croc to make his face appear as it did in Arkham Knight, which meant it's his actual face in the final game.
  • Canisters full of Scarecrow's Fear Gas appeared as Easter Eggs throughout Arkham City, most prominently in the Riddler's third hostage room: an area that was covered with razor wire which could be examined either in first person mode or by a Remote Control Batarang, and also at Hush's Hideout. Upon viewing these specific canisters, if you listened, you could hear strange voices in the room, that were possibly started by the leaking Fear Gas.
  • Scarecrow's face in Arkham Knight resembled a mutilated serial killer, rather fitting for a terrorist and criminal. He even considered releasing his Fear Toxin upon the world to be "terrorism in its purist form."
  • The fact that Scarecrow chose Halloween to attack Gotham further showed his fascination of fear, and why he chose to take advantage of the night that lore had said fear would be at it most powerful, since monsters, like Scarecrows, are said to be at their strongest on Hallow's Eve, which may explain how Scarecrow became more dangerous. But what Scarecrow may have or have not overlooked, is that creatures like Bats (like Batman and the Arkham Knight were modeled after), can draw power from this night as well, which may also explained why they both defeated him in the end. Additionally some of the rioters will comment that Scarecrow must have a sense of humor initiating his plan on Halloween, which is considered to be the scariest night of the year.
  • Scarecrow "getting a taste of his own medicine" in Arkham Knight seemed to have been taken from the first movie of the Dark Knight Trilogy, Batman Begins, and the episode "Nothing to Fear" from Batman: The Animated Series. In all three cases, Crane saw Batman as a demonic version of a bat. The only difference was that in Arkham Knight, the dose severely broke him into becoming harmless, while in Batman Begins, it made Scarecrow a lot more dangerous
  • From a certain point of view, Scarecrow won his last battle against Batman, as the Dark Knight's identity was revealed to the world, which forced Bruce Wayne to fake his death, though his legend was kept intact. His remark of this night being Batman's last was ultimately correct.
    • Scarecrow managing to unveil Bruce Wayne's identity to the people of Gotham and presumably the world gave him the distinction of not only being the only incarnation of Scarecrow to do so, but the only Batman villain in any medium thus far to succeed at that. An impressive feat, in overview.
  • The final nightmare that Scarecrow forced the player to experience in Arkham Asylum, specifically that of Batman going insane and the numerous Arkham inmates beginning to run the city, was fulfilled in Arkham Knight fittingly by Scarecrow himself.
  • In the Arkham Knight Novelization, Scarecrow was aware that Batman was hallucinating the Joker and revealed to the Dark Knight that he and Joker were working together. Joker contacted Scarecrow after he injected Batman with his blood and Scarecrow modified his Fear Toxin to bring out the Joker in Batman. However, it seems that Crane is unaware when the Joker surfaces in Batman as both times he either thought Batman was just acting different or wasn't afraid despite being injected with fear toxin.
  • When Batman was trying to put the canisters in place at Ace Chemicals, Scarecrow's old gas mask from Arkham Asylum could be seen laying on the floor. It could have been symbolic, for the self-destructive streak that Crane exhibited, or the departure from his formerly less serious self.
  • It seems that Crane had duplicates of his old mask, given there was one in Knight, and in City. It's quite possible that these masks were his calling cards to Batman.
  • In a sense of irony, Scarecrow adopts the kneeling position mentioned in Hugo Strange's rules for Arkham City - "if a TYGER guard approuches you for any reason, you must adopt a kneeling position with your hands behind your head. Failure to do so will be treated as an aggressive response and dealt with with extreme force" - but is hit by Batman regardless.
  • Despite Killer Croc being responsible for his mutilation, Scarecrow has never made any attempt to try exacting revenge. It's possible Crane developed a fear of Croc due to the mauling he received from him, or Crane's memory had become so twisted, he may have believed Batman threw him to Croc, like how Joker sometimes suggests Batman threw him in the tank of acid that lead to his transformation.
  • Save for Batman and Crane himself, all people that were infected with Scarecrow's new Fear Toxin died. Crane himself was supposed to be immune, but even he was permanently affected by the end of Arkham Knight. That gave an indication as to how strong the new Fear Toxin actually was.
    • The official website for Arkham Knight gave an indication that Scarecrow did in fact gain partial immunity to his toxin, presumably from having used it for his whole career. It is possible that his new toxin was strong enough to get past this immunity, however.
    • It is also possible that Scarecrow's immunity to the toxin only extended as far as decreasing it's physical lethality, as opposed to nullifying it's psychological effects.
  • For some reason, Scarecrow's face and personal attire slightly resembled Ermac's face and personal attire in Mortal Kombat X, mainly due to Ermac's face resembling an zombie as well as usually wearing hooded long robes. In some YouTube video images, they use Ermac instead of Scarecrow.
  • In Arkham Asylum, during the cutscene when Scarecrow was seen being taken by Killer Croc during his mauling, his cowl could be seen flying off his face for a split second, which meant that his cowl was not attached to the rag by his chest.
  • Some comic book incarnations of Scarecrow show that he was a psychologist, and some show him as a psychiatrist. In Arkham Knight, his bio shows that he is a psychiatrist and not a psychologist. So theoretically, this might be an indication (possibly an oversight or to reveal his true occupation) that with his knowledge of psychology and biochemistry combined, he is a psychiatrist in both the game series and the comics.
    • Scarecrow's display case shows that he has a Ph.D. in Psychology, but when his bio showed that he is a psychiatrist, it's supposed to be showing that he has a medical degree (M.D.) in psychiatry; this is possibly an oversight as well. To become a psychiatrist, you would need to complete medical school in order to earn an M.D. in the field.
    • While Batman is suffering Scarecrow's toxin, it is assumed that Scarecrow flees the Medical Facility and is not actually there while Batman is seeing Scarecrow in his nightmare.
