Bat Woman & back story

Katherine "Kate" Kane, alias Batwoman is the daughter of a Colonel Jacob Kane and Captain Gabi Kane. Her parents were both career military and worked extensively with military intelligence services.

Katherine grew up with her parents and her twin sister Elizabeth Kane. As her parents were promoted they moved to a wide variety of towns and bases. Her father was often away from home.

The Kane family moved to Brussels in Belgium, since her parents were now serving at NATO. The family however was torn apart due to a terrorist attack. Gabi was taking her daughters for the day, they were kidnapped by heavily armed men from the Religion of Crime. Military intelligence eventually located the hostages, and Jacob was put in charge of the tactical unit that was sent to rescue them. However they were too late as Gabi had been executed along with Elizabeth. Jakob rescued Kate himself, but she was traumatized by the sight of her dead mother and sister.

Kate tried to please her father by entering the Marines. At West Point, she roomed with Cadet Captain Sophie "Gimme" Moore, with whom she also entered in a lesbian relationship. Her commander got wind of it, and inquired about it. She confirmed her sexual orientation, but protected Sophie. Per the DADT policy, she was dishonorably discharged. Her father forgave her, and found it more important that she did not lie to save herself.

Jacob Kane eventually married weapons heiress Catherine Hamilton. This new wealth established Kate as a socialite in Gotham City's upper crust. She became notorious for her partying and drinking.

One night after a party, she was pulled over by officer Renee Montoya. Instead of being fined for drink driving, the two entered in a relationship. They broke up when Renee told her she had no direction in her life, no education, and no apparent goal. She found her purpose soon enough: when she was confronted by a mugger in an alleyway, she was saved by Batman.[2]

She decided to become a vigilante too. With her father's help, she traveled all over the planet for two years to learn how to fight. Her father used to family fortune and connections to come up with experimental weaponry.
