Helena Kyle

Helena Kyle was born and raised in the city of New Gotham. Her mother was the metahuman Selina Kyle, the legendary "queen of the criminal underworld" who went by the pseudonym Catwoman. Years ago, Catwoman had an affair with her greatest adversary, New Gotham's guardian, the Batman. Selina (presumably retired from crime), raised Helena on her own, and Batman was unaware that he had sired a child with her. Growing up, Helena became close friends with one of the Batman's protégés, Barbara Gordon. Helena never knew that Barbara was also the costumed crime-fighter known as Batgirl.
