Kate Kane

"Sitting at that desk, staring out that window, watching this city that we grew up in rot at its core, you find a way not to break."

- Kate Kane to Kara Danvers

Kate Kane is a female Human who is a wealthy individual and the cousin of Bruce Wayne. She is secretly the vigilante known as Batwoman.

Becoming Batwoman
At some point before the disappearance of Batman, Kate became a vigilante known as Batwoman in Gotham City. She also took charge of Wayne Enterprises after her cousin left Gotham as well, planning to redevelop it into a real-estate development firm.

Meeting other heroes
At some point after reality was altered, Batwoman stood on a clock tower in Gotham.

After Oliver Queen, Barry Allen, and Kara Danvers were arrested. Kate posted their bail and had a guard escort them to Wayne Enterprises. Once they got there, she reluctantly offered to help so they could leave, as she didn't want "Oliver" to cause any more problems. She took them to the rooftop and gave them equipment to use to find who they were looking for while she watched them on a security camera. After a while, Kara came inside. Kara apologized for asking a lot of questions, realizing the name Bruce Wayne was somewhat notorious. Kate said she knew, as Bruce is her cousin. Kara mentioned that her cousin was frenemies with Bruce, then wondered if keeping his private life a secret broke him. Kate responded by saying that watching the city fall to pieces makes it hard to break and that Bruce was possibly forced to leave. Kara complimented her and then asked about John Deegan. Kate told her that he worked at Arkham Asylum. After Kara left, Kate took an elevator down to a cave, where her suit was located.

When Barry and Cisco were attacked by Arkham inmates she appeared as Batwoman and took down the remaining inmates including Psycho Pirate. She told them that Kate told them to leave and that they should have listened to her and walked away.

Later when the Flash and the Green Arrow were fighting each other, she neutralized them and made them realize that they were exposed to a hallucinogenic gas. At the asylum gate, she told them to get out of her city and had a chat with Supergirl who knew her identity because of her X-ray vision. She recognized Kara Danvers from earlier. They shook hands and then walk away.

After reality was restored back to normal, she contacted Oliver Queen asking if the deranged doctor they brought into Arkham was going to be a bigger problem since he already made a friend at the Asylum: the Psycho Pirate.

Potential future
Batwoman may be involved in the Crisis of 2392, along with the Flash, Supergirl, White Canary, and other heroes.

Erased future
When the Crisis of 2392 originally took place on April 25, 2397, Batwoman, among others, was involved in the events. During the crisis, the Flash fought the Reverse-Flash before disappearing from the timeline. However, based on various witness claims, there are contradictory versions of the events (whether the Flash was assisted by Supergirl and the Atom, or a team of Green Arrow, Batwoman and Elongated Man).

Personality
"I don't do tearful good-byes."

- Kate Kane to Kara Danvers

Similar to her cousin, Kate is a no-nonsense and blunt individual. She is very open with her personal opinion. As Batwoman, she is very stoic and committed to helping Gotham City. While mostly an antisocial person, she can show respect to those she thinks deserves it, as she acknowledged Supergirl's worth as a hero. She is similar to Alex Danvers and Sara Lance.

Abilities
"Wherever your cousin is, I'm sure he's really proud of you."

- Kara Danvers


 * Peak of human physical condition: As a vigilante, Kate is in the best physical condition, strong enough to throw her enemies into the air and quickly master opponents much larger than her with relative ease. In fact, her physical strength seems to be even a bit inhuman, as she succeeded to lift and throw around full grown men with ease. Cisco Ramon referred to Kate as "badass" moments after witnessing her in action. Supergirl stated that she and her would make a good team, not dissimilar to their cousins' relationship.
 * Acrobatics/Free-running: Since becoming Batwoman, Kate has developed free-running skills and can fall from a height of several feet without hurting herself. Her abilities allow her to dodge and attack with fluidity from different directions without losing balance. She has also shown to be capable of reaching the tops of skyscrapers throughout Gotham.
 * Master hand-to-hand combatant/Martial artist: Kate is a highly competent unarmed combatant and an extremely skilled martial artist. She was able to quickly subdue Oliver Queen, a master martial artist in his own right, and Barry Allen simultaneously when reality was altered and they had each other's powers and skills, although it took them by surprise. Her fighting style so far is comprised of boxing, tai chi, kung fu, and she has also displayed skill in grappling her opponents in a fight.
 * Expert knife-thrower: Kate has shown to have great accuracy when she threw her Batarang at an escaped inmate at Arkham Asylum and caught it when it returned to her after subduing the inmate.
 * Intimidation: As Batwoman, Kate has an intimidating appearance, capable of instilling fear in her enemies. This was seen when a criminal, from Arkham Asylum, cried out of fear when he saw Batwoman.
 * Keen intellect: Kate is a very perceptive individual, as she quickly determined that Supergirl was Kara Danvers. Conversely, she is good at keeping her own identity a secret, as the highly intelligent Green Arrow, Flash and Danvers were unable to deduce her alter ego; Danvers had to resort to using her x-ray vision to discover who Batwoman was.
 * Stealth/Infiltration: Kate is extremely secretive, being able to approach other people without being sensed.

Equipment

 * Batwoman suit: Kate wears a protective suit as Batwoman, to hide her identity from her enemies when she goes out fighting crime.
 * Red wig: Kate wears a fake red wig to protect her identity from her enemies and while fighting crime.
 * Batarang: Kate uses a roughly bat-shaped throwing weapon.
 * Grapple gun: Kate uses a length of monofilament wire attached to a spool, and primarily is used for scaling buildings and ensnaring targets.
 * Recording Device: Similar in shape to the Batarang, but it includes a recording device inside in order to listen in on both Roger Hayden and John Deegan inside Arkham.
