The daughter of Gotham mafia boss Henry Aquista, Darla Aquista did not approve of his criminal activities. She befriended Tim Drake at her High School and developed a romantic attraction for him. However, she was gunned down at the school during a citywide gang war, with Tim and others unable to prevent her death.
Following her death, her father toured the globe searching for a way to revive her, eventually seeking out Johnny Warlock and telling him that he'd be prepared to die to bring Darla back. Warlock took him at his word, and Darla was reborn as the Warlock's daughter, in possession of formidable mystical powers. She has a burning hatred for Robin and a great love for Tim Drake, but is unaware they are the same person. She is capable of great evil, but seems reluctant to follow this path.
