Jonathan

Taunted and bullied in his youth, Jonathan Crane has 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, if not the most dangerous. Scarecrow is, on certain occasions, more of a threat to Batman than the Joker. 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.

This attack from Croc left Crane with a damaged retina, a permanently broken leg, and the lower portion of his face ruined and shredded. He only survived the attack by grasping onto a loose box of Titan that had become lost in the sewer system. Crane managed to rebuild his face, but heavily mutilated it to look like his original mask.

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 of himself, Scarecrow was left to suffer visions of his greatest fear, which is ironically swarms of enraged bats 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.

Scarecrow's appearance was vastly different due to the injuries that he had sustained at the hands of Killer Croc. Scarecrow's right eye became permanently white, implying it had been blinded, however it was his face that received the worst amount of damage from Killer Croc: huge chunks of his face had been removed during his mauling, with his nose and lips being completely gone. Because of how drastic his appearance was now, it was no longer clear how much of his face was a mask or the scar tissue caused by his mauling, however, rumors began spreading that Scarecrow's current appearance was actually the result of reconstructive surgery following Killer Croc's attack, purposefully done to make his face resemble his original mask, with pieces of string surgically grafted onto where his upper and lower lips were to further the resemblance to his burlap sack mask. His left 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.
