The Scarecrow is a fictional character, a supervillain that appears in comic books published by DC Comics. The character first appeared in World's Finest Comics #3 (Fall 1941) and was created by Bob Kane and Bill Finger. His alter ego is Dr. Jonathan Crane, a psychologist who uses a variety of drugs and psychological tactics to exploit the fears and phobias of his adversaries. He is a member of Batman's rogues gallery.
Although he made only two appearances in the Golden Age of Comic Books, the character was revived during the Silver Age of Comic Books by writer Gardner Fox and artist Sheldon Moldoff in the pages of Batman #189 (Feb 1967) and has since become a staple Batman villain. The Scarecrow has been featured in other DC Comics-endorsed products such as feature films, video games, animated television programs, and merchandise such as action figures. Irish actor Cillian Murphy portrayed the Scarecrow in Christopher Nolan's Dark Knight trilogy. He was voiced by Henry Polic II on Batman: The Animated Series. In 2009, the Scarecrow was ranked as IGN's 58th Greatest Comic Book Villain of All Time.
