Arkham Asylum

Arkham Asylum was a mental asylum in Gotham City in various universes.

In one such reality, Poison Ivy was imprisoned there until the apparently-corrupt heads of the Asylum allowed her to be transferred to a private Arc Mechanics laboratory to serve as a test subject for a new device for interrogating and studying “metahumans” like her.
