Pre-Final Crisis (2006)
Kate Kane’s Batwoman first appeared in 52 #7 (2006). Soon after her first appearance, her former girlfriend Renee Montoya learned, via Intergang’s Crime Bible, of a prophecy that the “twice-named daughter of Cain” would be murdered. Kate worked with Montoya (as the vigilante known as the Question) in thwarting Intergang’s plans. In the wake of Batman’s absence following the events of FINAL CRISIS, Kate played a greater role in defending Gotham City, beginning with DETECTIVE COMICS #854 (2009).
Elegy (DETECTIVE COMICS #854-857, 2009)
The “Elegy” storyline found Kate hunting down Intergang, operating under its new “Religion of Crime.” Little was known at first of Kate’s past, but here her backstory was slowly revealed. She discovered the Religion of Crime’s Lewis Carroll-fixated leader/“High Madame” Alice was her long-thought-dead sister Beth. She stopped Alice/Beth from poisoning Gotham with a toxic gas, but at the cost of once more losing her sister. “Elegy” also introduced Kate’s cousin, Bette Kane, whom she would train to be the Super Hero Flamebird.
Unlike that of many DC Super Heroes, most of Batwoman’s history was not rebooted in the New 52 universe. Instead, after the events of “Elegy,” Kate Kane joined Batman Incorporated and helped the organization take down Talia al Ghul, who’d taken control of the League of Assassins after the death of her father, Ra’s al Ghul. Kate also maintained a relationship with another law woman—Maggie Sawyer.
In DC’s Rebirth, Kate Kane was recruited by Batman to train and lead a new team of allies, including Clayface, Red Robin (Tim Drake) and Spoiler. This put her at odds with her father in the “Rise of the Batmen” storyline, in DETECTIVE COMICS #934-940 (2016), when he launched a rogue military operation code-named “The Colony.”
