Arkham Asylum.

“Babs” is the daughter of Gotham’s Commissioner Gordon and has been romantically linked to Dick Grayson. At a young age, they shared their passion as Robin and Batgirl; as the years went on, she found her role less fulfilling, and she eventually retired. That’s when Joker showed up at her house, shooting and paralyzing her, ending her crime fighting career. Recognizing she could no longer be the kind of hero she had been, she devoted her time developing one of the world’s most complex computer systems and set to work accumulating information, renaming herself Oracle. Blessed with a photographic memory, Barbara reads dozens of the world’s top newspapers daily. She’s also constantly gathering info from sources such as the CIA’s mainframe, data networks of the FBI and Interpol (without their knowledge or consent). Oracle has formed an alliance with fellow heroes Black Canary and Huntress; together, they’re the Birds of Prey, combining their unique abilities and skills in the war against crime and terror.
