Batman of Arkham (DC, 2000)
In this Elseworlds tale, circa 1900, Bruce Wayne runs the place -- a respected psychiatrist by day and a vigilante helping to fill the asylum's cells by night. His treatments are thorough and compassionate, a significant change from usual portrayals of the asylum, and he measures a fair success rate with his patients.
