Fan Casting Lady Shiva in Return to the DC Universe

Sandra Wu-San has always been a skilled martial artist. She and her sister Carolyn grew up together in Detroit, with people coming to see them spar frequently. One day, David Cain, who would father Cassandra Cain aka Black Bat with Sandra, noticed that Carolyn held her back, so he killed her, and led Sandra to find her. Exploring her true potential, she tried to seek revenge, but didn't succeed in it, eventually becoming a mercenary as Lady Shiva. Flitting between good and evil, Lady Shiva's motivations are all her own, her skills a threat.
