Scarecrow

"Are you trying to frighten the Scarecrow? You'll have to do better than that."

- Scarecrow

The Scarecrow is an insane ex-psychiatrist who uses a variety of drugs and psychological tactics to use the fears and phobias of his adversaries. He does not commit his crimes for wealth, but rather as a form of "research" to further study the effects of fear on humans (later, he does it to satisfy his own psychopathic desires), making the innocent citizens of Gotham his unwilling guinea pigs.

The Scarecrow uses a variety of toxins that cause his victims to hallucinate that their phobias have come to life. He wears his Scarecrow mask to enhance the effect of the hallucinogen (instilling fear in all who see him) as well as to avoid being poisoned by his own toxin. Although not physically intimidating, Scarecrow is adept in physical combat, using a style called "violent dancing", based partly on the crane style of kung fu and on drunken boxing.

The Scarecrow is an expert in psychology, with a focus on fear, and is a former certified professor on the subject. Due to prolonged exposure to his own gas, Scarecrow went from being frightened of bats to only being frightened of Batman. Scarecrow is both addicted to fear and incapable of fearing anything except Batman, whom he compulsively seeks in order to ease his addiction after the Caped Crusader's apparent death.

The Scarecrow at times wields a scythe which he uses in addition to his "violent dancing". Scarecrow also uses a hand-held fear gas sprayer in the shape of a human skull, straws which he leaves as a calling card, special straws which can be snapped in half to release a fear toxin, and stuffed scarecrows which scare his victims.
