Fictional character biography
Alice's origin is told in flashback. Beth Kane is the identical twin sister of Kate Kane, and the daughter of Jacob Kane and his wife Gabrielle Kane, both career soldiers in the U.S. Army. The Kanes are Jewish, and Jacob Kane inherited vast wealth along with his other siblings. Bette Kane (the superheroine known as Flamebird, and later Hawkfire) is a cousin, and Bruce Wayne's mother Martha Kane Wayne was Jacob's sister.
Jacob Kane is promoted to colonel and assigned to NATO headquarters in Brussels, Belgium. When the twins turned 12 years old, their mother took them to a restaurant for a birthday dessert. A terrorist group (later revealed to be the organization known as the "Many Arms of Death") kidnapped the family, and Col. Kane led a rescue mission to save them. During the battle, Gabrielle was murdered by the terrorists. The terrorists kidnapped another young girl and murdered her too. Kate, seeing the body of a young girl under a blanket, is left with the impression her sister died. Col. Kane, however, knew that the terrorists had Beth. Despite looking for years, Col. Kane never found Beth. He never told Kate that Beth might still be alive. The Many Arms of Death needed twins to rule their organization, but since Kate Kane was rescued this meant Beth was not useful to them. Beth's fragile psyche led the Many Arms of Death to send her to the United States, where she was raised by the Religion of Crime.
