To those who don't know her, pick up a comic book  she's the daughter of Deathstroke, AKA Slade Wilson. She stabbed out her own eye when her daddy had her hopped up on some drug, but she went a little nuts from it and tried to "be more like him". Ouch. Eventually, she left Slade to join the Titans, and ended up developing a close relationship (not incest, pervs) with her brother Joseph Wilson, AKA Jericho. He went bonkers, too, at some point.
