Lady Shiva (real name Sandra Woosan, or more recently Sandra Wu-San) is a fictional comic book character co-created by Dennis O'Neil and Ric Estrada, and published by DC Comics. She first appeared in Richard Dragon, Kung Fu Fighter as an antagonist of Richard Dragon. Over time, she has become more closely associated with Batman and related characters, both as an enemy and an ally. She is a martial arts grandmaster, one of the most skilled combatants in the entire DC Universe. She is an assassin-for-hire, who specializes in killing her targets with her bare hands.
Sandra Woosan is first introduced as an antagonist to martial artist Richard Dragon, believing him to be a spy responsible for the murder of her sister Carolyn. In reality, Carolyn's murder was orchestrated by Guano Cravat, a corrupt businessman whose criminal ambitions had been foiled by Dragon. Cravat convinced Woosan that Dragon killed Carolyn, deliberately pitting her against Dragon in an act of revenge.
In order to avenge her sister, Woosan becomes a master combatant. During the course of her training, she discovers that she is a prodigy, rapidly mastering several martial arts and eventually dubbing herself "Lady" Shiva.
When Shiva tracks Dragon down and lures him to Cravat's hideout, Dragon reveals Cravat's deception. The Swiss, Carolyn's real murderer and Cravat's underling, had already died in battle with Dragon, rendering Shiva's vendetta moot.
