The alter-ego of Jonathan Crane, the Scarecrow first started off being the object of Jonathan's terror, being constantly haunted by an illusion ever since being injected with the fear toxin created by his father.Being bullied, harassed and tormented by a gang wanting to exploit his knowledge in the creation of the gas, his psyche broke down, eventually hearing the voice of the scarecrow they were using to control him speak his name. He set about starting to embrace his own fear, wanting to get revenge on the people who had locked him away and threatened him.
Scavenging around the room he was left in for supplies, Jonathan made himself a costume to embody his new persona, fitting dispensers into the suit that allowed him to use samples of the fear toxin that he had kept hidden on his person as a means of self-defence should any of the gang attempt to hurt him.
"A Dark Knight: Pax Penguina"Following the arrest of Merton and the other members of his gang at the Iceberg Lounge opening night, Grady Harris returned to the gang's safe-house, yelling upon entering that he wanted Jonathan to produce more of the toxin so that they could break Merton out of prison.
But upon unlocking the door to Jonathan's makeshift cell, he is startled to find that the scarecrow that they had been using to intimidate the teenager was dismantled, with the garments forming a new costume for the boy to wear.
Turning on his captor, he remarked that Jonathan Crane was all but gone, demanding to be called the Scarecrow. Advancing on Grady, he doused the criminal with fear toxin, watching as his tormentor was left reeling and panicking in a small heap on the floor.
