Children of Arkham (Earth-6531)

The Children of Arkham were a terrorist group led by the mysterious Arkham Knight, secretly the Gotham Gazette journalist Vicki Vale. The name referred to the children of multiple individuals who were wrongfully committed to Arkham Asylum, but it also contained numerous street criminals and mercenaries. Their goal was to expose the corruption of Gotham City and bring down those who ruined their family's lives, such as Carmine Falcone and Mayor Hamilton Hill, and the Wayne family.

History
During the 1970s, Thomas Wayne, Carmine Falcone and Mayor Hamilton Hill, who ruled Gotham City, were able to use their power and influence to convict many of their political enemies and adversaries to Arkham Asylum under the pretense they were insane. In order to ensure their enemies were perceived as insane, the trio had these subjects have electroshock therapies and lobotomies, so they would act violently.

The Children of Arkham protest group was created some years after these events, in the hopes of exposing the lies hidden by the figureheads. However, their efforts fell short with no public support. However, with the appearance of Vicki Vale, the organization changed from peaceful to a terrorist cell.
