The Scarecrow is a brilliant psychologist turned supervillain who fights Batman in Gotham City, specializing in techniques and chemicals that manipulate fear. Jonathan Crane was originally a well-respected professor, although he lost credibility when he obsessively took his experiments too far and descended into madness. He spends most of his time in Arkham Asylum and has been a member of the Injustice League, Injustice Gang, Legion of Doom, Secret Society of Super-Villains, Sinestro Corps. Scarecrow was created by Bill Finger and Bob Kane, first appearing in World's Finest #3 (1941).
