Scarecrow

The Scarecrow (Dr. Jonathan Crane) is a fictional supervillain appearing in American comic books published by DC Comics. Created by Bill Finger and Bob Kane, he made his debut in World's Finest Comics #3 (September, 1941). He is one of the most enduring enemies of the superhero Batman and belongs to the collective of adversaries that make up the Dark Knight's rogues gallery.

As the self-proclaimed "Master of Fear", the Scarecrow is an overly-obsessive and deranged ex-professor of psychology who uses of a variety of experimental toxins and psychological tactics to exploit the fears and phobias of his victims and adversaries, especially Batman's. Unlike most criminals, he does not commit his crimes for wealth, but rather as a form of "research" to further study the effects of fear on humans (which would eventually evolve into a way to satisfy his own psychopathic desires), making the citizens of Gotham City his unwilling guinea pigs.

Abilities : Expert in psychology and biochemistry. Skilled in the use of a scythe. Utilizes fear-inducing gas and toxins.
