Scarecrow is a supporting villain in Batman Unlimited: Monster Mayhem.
History[]
He, along with Solomon Grundy, Silver Banshee, and Clayface, were broken out of Arkham Asylum by Joker as part of his plan to take over Gotham City by kidnapping computer game designer, Goto Shoto, and infecting all the technology around Gotham with a digital laughing computer virus. During his announcement to Gotham, Joker reveals that he made Scarecrow his financial accountant.
During a confrontation with Batman and his allies at Joker's hideout, Scarecrow infects Nightwing with his Fear Gas, leading him to see reflections of his past life as Robin, but Nightwing overcomes his fear and defeats Scarecrow. While the heroes left the villains for the police, Joker frees them and sends them out to get on with his parade while he sends his computer virus worldwide.
Scarecrow was eventually defeated by the heroes after Joker's defeat, and taken back to Arkham.
