Scarecrow plays a prominent role in Doug Moench's "Terror" storyline, set in Batman's early years, where Professor Hugo Strange breaks him out of Arkham and gives him "therapy" in order to train him to defeat Batman. Strange's therapy proves effective enough to turn the Scarecrow against his "benefactor", impaling him on a weather vane and throwing him in the cellar of his own mansion. The Scarecrow then uses Strange's mansion to lure Batman to Crime Alley, and decapitates one of his former classmates in the alley in front of Batman. With the help of Catwoman—whom Scarecrow had attempted to blackmail into helping him by capturing her and photographing her unmasked—Batman catches Scarecrow, but loses sight of Strange, with it being unclear whether Strange had actually survived the fall onto the weather vane, or if Scarecrow and Batman are hallucinating from exposure to Scarecrow's fear toxin.
