Socktor Jonathan Crane, better known as the Scarfcrow, is one of Hatman main shoepervillains. He used to be a psychiatrist at Arkham Asylum who was obsessed with fear. In the Asylum he used fear-inducing experiments on the patients. At the same time he was also a psychologist teacher at Gotham University, however he was fired when he fired a gun in the middle of a classroom, wounding a student. He takes revenge by killing the proffessors responsible for his firing and subsequently takes on the carreer of a criminal.
Armed with his selfmade fear gas, a gas that when inhaled makes you see your biggest fears, he has tried and failed to defeat the Hatman many times.
