The Batwoman is a vigilante inspired by the urban myth of the Batman. Operating from a hidden base within the R.H. Kane Building, Batwoman is an ex-military operative who has spent over two years amongst mercenaries training specifically for the role of saving Gotham's citizens from the murder and chaos that has plagued the city.
Donned in the colors of war and death, Batwoman is relatively new to the Hero community but she has already proven herself competent; targeting Intergang's Cult of Crime in a one-woman operation to shut the cult down before the cult turns Gotham into Hell on Earth.
Jacob "Jake" Kane was born into the Kane family; one of Gotham's four founding families (alongside the Wayne Family, Cobblepot Family and the Elliot Family) and a family famed for owning everything in Gotham that the Wayne Family did not. Working in the military, Jake eventually met and married a woman named Gabbi and fathered twin daughters; Katherine "Kate" Kane and Elizabeth "Beth" Kane.
As the sisters grew they became inseparable in spite of their differing personalities; while Beth was more demure and controlled; like their father, Kate was more brash and impulsive.
On their twelfth birthday, Kate and Beth were treated to a dinner at a restaurant with their mother, however, the night ended badly when the trio were kidnapped and held for ransom. Now a military colonel, Jake launched a rescue attempt but the kidnappers had already executed his wife and Beth.
With her mother and sister dead, Kate latched onto her father's stability and attempted to emulate him; to keep the rage and sadness she had over her sister and mother's deaths in check.
Her newfound focus saw her grades reach the top of the class, in addition to performing in all-state gymnastics before gaining admittance at the United States Military Academy in West Point.
Earning excellent grades at the academy, Kate fell for a girl who was as unflappable and calm as her father and began a relationship only to be discovered and drummed out of the military after refusing to lie about her sexuality.
Returning home and discovering that her father had moved on from his wife and daughter's deaths and married a new wife, Kate discovered that she couldn't let go of their memory and fell into depression and lost herself in the nightclub scene; turning to alcohol to numb the pain of her lose and failures.
Having no life direction and no outlet to express herself Kate was on a road of self destruction until a chance mugging-attempt, which she thwarted herself, resulted in her encountering the Batman and she became inspired to likewise fight crime. Secretly gathering military gear and weapons, and hiding them within a panic room in her apartment, Kate embarked each night in pursuit of robbers and muggers; becoming addicted to the thrill it brought her.
Eventually, Jake discovers his daughter's equipment, but instead of attempting to dissuade her, he comes to agree with her reasons to aid Gotham's victims and sends her on a two year training regime with a team of guns-for-hire with whom he had worked with previously.
Now fully trained and more than ever dedicated to her new mission, Kate returns to Gotham to find a Batsuit and her panic room converted into a secret bunker ready for her use as the new Batwoman.
