Who is Batwoman (Kate Kane) in DC Comics and what is her origin story?

Kate Kane is the third character to take on the mantle of Batwoman in DC Comics. Created by Geoff Johns, Grant Morrison, and Alex Ross, she debuted in 2006. Her origin involves witnessing her mother and sister being murdered during a robbery attempt, which deeply traumatized her. She later discovered her father, Jacob Kane, had been secretly working with corrupt military officials. This led her to train rigorously in martial arts, detective skills, and tactical combat, ultimately becoming Batwoman to fight crime in Gotham City, operating outside the shadow of Batman and often focusing on issues he overlooks.
