Fan Casting Scarecrow in Batman: Arkham Asylum

Joker and Scarecrow were prepared to enact the plan that they formed. Harley Quinn was allowed to aid the orderlies and gained access to restricted areas after she deceived them into believing that she had reformed, and released several of the inmates on Joker's "party list," including Crane. As part of the Joker's scheme, after he assumed complete control of the asylum, Scarecrow led Batman to the Medical Facility, where the villain pumped the elevator that Batman was in full of Fear Gas. As Batman made his way to the bottom floor, he saw Scarecrow spray his Fear Gas into an operating room of Arkham staff and patients, and caused them to panic to the point of death.
