Kate Kane

"I spent fifteen years searching for a place I fit, and I think I've finally found it. Some see fear, others hope. I see the freedom to be myself, to play by my own rules."

- Kate Kane

Katherine "Kate" Kane (born January 1990) is a wealthy individual, the daughter of Jacob Kane and the late Gabi Kane, the twin sister of Beth Kane, the step-daughter of Catherine Hamilton-Kane, the step-sister of Mary Hamilton and the cousin of Bruce Wayne. After returning to Gotham City to save Sophie Moore from Alice's gang, she learned of Bruce's secret identity as Batman and took up his mantle and started operating (secretly) as the vigilante known as Batwoman.

Early life
Kate was born in January 1990 to Jacob and Gabi Kane, along with her twin sister, Beth, growing up, Kate was very close to her cousin Bruce Wayne, who was like an older brother to her, when she and Beth were little, they once visited Wayne Enterprises, where Kate convinced Beth to sneak into Bruce's office, Kate noticed a woman's necklace in a square pyramid-shaped glass container. She was about to touch it, when Beth stopped and convinced her to leave the office immediately.

In January 2003, Kate and Beth were in a car driven by their mother on their way home from their Bat Mitzvah when they were rammed by a school bus hijacked by the Joker, the family's car veered off of the road, almost going over a bridge until it was stopped when Batman arrived and attached a grappling hook each to the bridge and to the car, believing the car was safe, he immediately left to save the children on the bus from the Joker, the pillar of the bridge slowly began to give way; Kate quickly climbed out of the car, shouting for Batman and asking why he was leaving so suddenly, Beth tried to wake their mother, to no avail. Kate reached out for Beth's hand, but it was too late, and the bridge's pillar gave, plunging into the cliff's river below. Due to these events, Kate started believing Batman only cared about catching the villain.

The tragedy left Kate and her father, Jacob broken, though Bruce comforted Kate through her healing process, sometime during Beth's disappearance, a Kate had a nightmare, and Jacob hugged her tightly, even though she had a bed, she slept in the living room in case Beth called, she then made her father promise they'll never stop looking for Beth, later, Jacob brings Kate waffles, but Kate doesn't want to eat them, she says that they should instead be looking for Beth, however, her father points out that they've been looking for months and deserve a break, however, Kate tells her dad she feels like this was all her fault because Beth went to check on their mom, but instead of helping, Kate climbed out, she feels like she could have tried harder to save her sister, but was scared that if she stepped too far, she'd fall down too. Later, Jacob tucks a blanket over a sleeping Kate and sees a map of the area where the car went off the bridge, and the places they have already checked for Beth.

Jacob breaks into tears and walks away with it, he crumbles it just as he sees Kate is awake once more and is seeing him crying, Jacob calls her over and holds her tightly, he tells her that investigators found skull fragments on a nearby farm and had them tested, and they belong to Beth, Kate (correctly) doesn't believe it, as she had already checked the farm on multiple occasions and calls Jacob a traitor for giving up before walking away. At some point, her father married Catherine Hamilton, and Kate met her step-sister, Mary Hamilton.

Meeting Sophie Moore
Wanting to join her father, Jacob's Crows Security, Kate studied at Point Rock Academy, where she met Sophie Moore. Despite the military's strict code of conduct against homosexuality, the two fell in love with each other and would secretly sneak off somewhere secret to make out.

Expulsion
A week before graduation, Kate and Sophie sneaked to the back of a shed, where they made out and engraved their names into the wood. However, a superior caught them. The academy made them deny the homosexual allegations against them, but Kate defied their orders and quit the academy, as opposed to Sophie, who wanted to graduate and accepted the school's offer. Due to their different ideals, the two broke up.

Training
In 2013, Kate's father, Jacob suggested that she leave Gotham to travel around the world and, train under combat and survival specialists. Presumably, she received news of Bruce and Batman's disappearance from Gotham around 2015.

Meeting Alice
By 2018, Kate was training under an old man in a barren icy region, she suddenly received a call from Mary, who informed her of Sophie's kidnapping by Alice's gang, Kate immediately left for Gotham City earlier than she would've wanted to, heading straight for Crows Security, where she visited her father. She asked for Sophie's whereabouts and offered her assistance to the Crows, but her father disagreed and left to answer a call.

Wanting answers, Kate drove to Wayne Enterprises to use the Wayne Security system, she scaled the building, arriving in Bruce's office and reminiscing over her time sneaking inside with Beth when they were little, suddenly, the head of Wayne Security, Luke Fox, held Kate at gunpoint, knowing she was going to be cuffed, she secretly grabbed a paper clip and went with him, she tried introducing herself as Bruce's cousin, but Luke refused to believe her, he took Kate to the surveillance room and called the police, when she broke free and cuffed Luke to a system unit, taking his keys. Kate logged into the system, copying surveillance of the gang and leaving Luke's keys for him just out of his reach.

Arriving at her father's house, Kate was surprised with a welcome-home party, she was bombarded by Mary's rambling, when Kate interrupted to ask why Mary called her from her training, Mary revealed that she had accidentally discovered a box of pictures of her and Sophie and thought that Kate would want to come home, they were interrupted by Kate's step-mother Catherine, who asked for Mary to do a picture with the councilwoman, behind her, she saw a picture of her father and Sophie's acceptance into the Crows and recalled their tumultuous history. Showing her father the surveillance footage, they tracked the gang down to Burnside Orphanage, where the Crows converged upon.

Kate went ahead first, fighting through a number of thugs, but ultimately being knocked out, coming to, Kate came face to face with the gang's leader, Alice, Alice taunted her for some time, before knocking her back out and having her taken to a makeshift clinic run by Mary, waking to find Mary stitching a wound on her arm, Kate headed back to Crows Security to inform her father of her findings. Instead of taking her intel, he became angry at her having run off, causing Kate to give up and do her own thing.

Becoming A Vigilante
Kate headed back to Wayne Enterprises, where she attempted to convince Luke to call Bruce, before he could do so, she noticed an out of place heirloom on the bookshelf, she moved it back into place, revealing a secret elevator, riding it down, despite Luke's objections, Kate discovered the Batcave, realizing that her cousin is Batman, seeing newspaper clippings regarding the accident in which she lost her mother and sister, Luke explained Bruce had thought he'd had the calculations perfect, only to make one slight miscalculation, having Luke repurpose Bruce's old Batman suit, Kate took it to ambush Alice's gang, she entered into a brief scuffle, before diving as a bound Sophie fell off of the side of the skyscraper, the two fell through an abandoned building, miraculously landing on a bed, Kate promptly fled, using her grapple hook. When she returned to the scene, Alice was gone, but noticed and took the knife that Alice had lodged into a wall.

Following this, Kate returned to Crows Security, where she ran into Sophie, they exchanged warm pleasantries, before Sophie's husband Tyler appeared, much to Kate's shock, Kate stopped off at her father's office, where he admitted that he had reservations because he was afraid of losing her like he did with his other daughter and late wife, but would accept if she wanted to join the Crows, Kate headed to the Batcave, where she began writing letters to Bruce. Examining a knife Alice had thrown at her, Kate recognized the jewel embedded in it, comparing it to the one on her necklace, and realized that Alice was her twin sister Beth all along.

Three days later, two Wonderland Gang members firebomb a Crow hummer, Kate attacks them as her alter ego and she is a bit surprised when the suit deflects their bullets. She gets in front of one of them as he runs and knocks him out. She removes his mask and asks him where Alice is, and then leaves as more Crows arrive at the scene. She drives through Gotham on her motorcycle, going to the Wayne Enterprises tower, taking an elevator to the Batcave and Luke asks her where she's been. He warns her that she can't continue to go out and pretend to be Batman, to which Kate insists that she's merely doing it as a way of finding Alice and to determine if she is in fact her sister, Beth.

The next day, Kate meets with Catherine and Mary for breakfast and, Jacob arrives and says that the Crows might not have killed the gang member if Kate had joined his security group, Mary brings up the fact that Sophie is married to a man, but Catherine advises her daughter to drop the subject all together, Kate suddenly says that Alice is Beth and explains that she got one of Alice's knives with a garnet birthstone like Beth had, Jacob insists that facts are facts and that Beth is in fact dead, as skull fragments had been found years earlier, Kate tells her father that she'll prove it to them and leaves them to finish the rest of their breakfast, Kate goes back to the Batcave and examines Alice's knife, she then looks at a photo of her and Beth as children. Luke arrives at the Batcave and tells Kate that while Wayne Enterprises does have a device that can analyze DNA against another sample, he was really just hired to watch over the building and keep the lights on. However, he says to Kate that he wants to talk about the Batman suit and proceeds to point out how the city wants a hero that isn't there, Luke warns Kate that Gotham City needs a hero and Kate has become one; whether she likes it or not, He then shows Kate several gadgets that Batman has at his disposal, including a laser saw and a rebreather, he warns her that they're all very dangerous tools and that quite honestly, he doesn't know how half of them work, Luke reiterates that this is because they were all meant for Batman. Kate taunts Luke by saying that this whole speech he gave her, sounded eerily similar to his father, Lucius Fox; except Lucius was at least useful.

Kate approaches Sophie at the Crows base and Sophie asks if "Batman" everyone is talking about is in fact Kate, Sophie insists that she hates Batman and also warns that Jacob hates Batman as well, so whoever is dressing up as Batman nowadays is really asking for trouble on Jacob's part, Kate denies it again and jokes with Sophie that if she were gonna save her in a dramatic fashion, she would have totally dressed as Wonder Woman to do so, instead of Batman, Jacob looks down from his office, and Kate takes Sophie somewhere private, she asks her to run the DNA on the knife, and Sophie insists that Alice isn't Kate's twin, Sophie warns her that Kate is getting her hopes up, and says that Jacob would kill her if he found out, Kate takes the knife back and switches topic, saying how she would have come back sooner to stop Sophie's wedding. Suddenly, a gas grenade rolls down the parking garage ramp and gang members come after the two women to get the knife.

Kate and Sophie fight them off, but one of the masked men grabs the knife and drives off with the others, later, Kate apologizes to Sophie for dragging her into it, Jacob complains that Kate brought Alice to the Crow's doorstep, and Kate wonders how Alice knew she had the knife, Sophie sides with Kate, but Jacob insists that Alice is a cop killer and must be stopped, Kate tells Jacob that somewhere deep inside of Alice, she's actually Beth, Jacob ignores her and says that the GCPD gave the Crows permission to put Alice down, an aide reports that they traced the second Crow from the night before and followed him to a section of town. Kate goes to Mary's clinic and asks to see the second gang member.

Mary has him under treatment and found a batarang in him, Kate says that he's one of Alice's gang and tells him to send a message to Alice; "waffles", she releases him and Kate tells Mary that if Alice is indeed Beth, she'll know what "waffles" means, when asking for more details, Kate tells her step-sister that it's better that she doesn't know, Kate later calls Sophie and asks her to stall the Crows while she finds Alice. Sophie realizes that Kate is referring to the Waffle Stand and Kate asks then asks Sophie to buy her some time so she can prove Jacob wrong.

Kate drives to the now-abandoned Waffle Stand and waits for Alice, Kate then hears Alice swinging on a nearby swing set and goes over to her, Kate asks Alice if she's really Beth, Alice toys with her when Kate asks her to prove that she is Beth, Alice says she is already here and knew the password was waffles and shares with her how they used to come every Friday to this waffle stand and gorge themselves in chocolate covered garbage, however, she then proceeds to say that she could also be lying because the little factoid she just shared could have been mentioned in the press and she might have read it online. Kate then reveals to Alice that she had her knife, while Alice continues to insist that they're sisters.

Kate points out that they found Beth's skull fragments and, Alice asks why she's there if that's the case, Alice describes the crash and how the thought of someone coming to save her was what kept her calm. Mary then texts Kate, asking her where she is, Alice says that Kate can answer that if she wants to. Kate texts Mary that something came up that is holding her up at the moment, when Kate says they have a lot to catch up on, Alice says she'd rather not she really just came to meet her here to ask her one question and that is when it was that Kate finally slept through the night after she disappeared, Kate says that she never did, because she feels like she should have been with Beth when she was in the crash. Alice then cuts her hand and gives her some blood to test her DNA, so she can get the proof she so desperately wants.

However, the Crows arrive shortly after with their guns drawn and, Kate steps between them and Alice, thus, shielding Alice from any potential kill shots, Jacob orders Kate to get out of the way, warning her daughter that Alice is just using her to get inside her head, they see that Alice has a weapon and Alice refuses to drop it, Kate warns Jacob that if he shoots then he won't just lose Beth, but her as well, not wanting to take that risk, Jacob orders his men to lower their guns and to instead take Alice to Arkham Asylum, Sophie approaches Kate, trying to justify telling Jacob her whereabouts, Kate is disappointed in her and goes instead to tell Alice that she hadn't told the Crows where they'd be meeting. Alice then asks Kate if she remembers why they each had to get their own waffle, and Kate proceeds to say that it was because Beth didn't like to share.

Kate later goes back to Mary's clinic not too long after as her alter ego and knocks out Dodgson, the power in the facility comes back and, Kate watches the TV as it comes on with the power and, a newscast shows that the van transporting Alice has exploded and subsequently fell into the waters under Loeb Bridge, Kate drives to the bridge and Luke calls her and warns her that the place is crawling with cops, undeterred, Kate speeds up trying to get to Alice in time, the van containing Alice sinks beneath the river waters and Kate gets her out using the laser saw while wearing the rebreather, she gives it to Alice to breath and Alice jerks awake and stares at her, the Crows shoot into the water, hitting the van and it explodes knocking the two women apart and opposite shores, Luke calls Kate several times as she lies unconscious, the police officers move in and Luke tells Kate to get up as a dog approaches her, he remotely activates the defibrillator built into the suit and by the time the police get there, she is gone.

Kate then goes back to the clinic, where Mary draws a gun when she hears someone behind her. When she realizes it's Kate, she lowers it. Kate apologizes for missing dinner the night before, Mary tells her that she understands Kate needs to know about Alice and says that Dodgson tried to kill her because Alice sees her as her replacement, however, she proceeds to tell Kate how Alice was in the wrong, since not once since their parents got married, has Kate treated her like a sister, she says that the most sisterly thing that Kate has done for her is pretending she doesn't exist, Kate tries to argue that it's not that way at all, but Mary doesn't believe her, Mary assures her that she didn't tell Jacob and asks her if Alice is worth all the trouble, Kate doesn't answer her and Mary asks her to tell Alice that she's not a threat. Kate then goes to Crows security, where her father is demanding to know how Alice escaped.

Kate tells Jacob that he's about to kill his own daughter, Jacob shows her the photos of a family Alice had killed and says that his Beth wouldn't have killed them, he tells Kate to drop it or he'll have her arrested and Kate storms out, Sophie tells Kate that Alice could have killed her, Kate accuses Sophie of lying to the military academy and selling her out, Sophie argues that wasn't the same thing and insists that she'd never lie to Kate, when Kate asks her if she's happy, Sophie says that she is and there is no "them". She tells Kate to move on and leaves.

The next day, Kate goes to see Luke, she thanks him for saving her, but as Luke looks to be tearing up, she tells him that they should get so emotional and they drop it, she tells him that she knows it wasn't Alice and her gang that took the knife, she theorizes that there's someone else out there who doesn't want her to know the truth about the DNA on that knife, Kate writes in her journal to Bruce that the people of Gotham want hope and she found someone she didn't know or recognize in Alice. Now instead of hope, she feels doubt. That night, Batwoman beats the captive Dodgson for answers as she wants to know everything he knows about Alice, Kate returns to her bike and finds a case left for her. There's a bat inside, and there's a note saying that Kate has her father's eyes, revealing that Alice not only is Beth, but that she also knows that Kate is the bat vigilante.

Becoming Batwoman
10 days later, Kate writes to Bruce to tell him how Alice has figured out she was the one putting on the bat suit. She explains that she put on his suit to terrify Alice and her gang, but that it can't protect her now that Alice it's her inside the suit. Kate feels like she has lost her advantage, and in the process has inadvertently given Gotham their hero back. She admits that she didn’t sign up for this part, as she never meant to give the city so much hope. She finishes this journal entry to her cousin telling him that she can’t do this because she's not Bruce or Batman.

Later, Kate is called into action when someone flashes the bat signal onto Wayne Tower. It turns out it was Alice who called Kate using the bat signal, but also makes rabbit ears using the light from the aforementioned bat signal. When Kate gets there, Alice sarcastically says how it must be broken because it was supposed to call Batman not Kate. She reminds Kate that putting on the suit hasn't changed anyone's life and that being a hero is not her strong suit, since she let Jacob declare her dead after not helping her escape from the car. Alice asks how she can get Dodgson back, to which Kate says that if she can stop killing people for 24 hours then she'll reassess the situation. Alice begrudgingly agrees but says that if Kate is trying to save Beth, that she can't because Beth has gone down the rabbit hole and will never come back.

Kate returns to Wayne Tower, only to find Tommy Elliot inside Bruce’s office. Tommy then proceeds to tell her that he now has more money than Bruce, and points to a building he just bought - five stories taller than Wayne Tower. Kate asks why he’s there, and Tommy says he is here to invite Bruce to his party. Kate says he isn’t back, and Tommy goes onto talking about how Gotham’s Dark Knight has the city swooning after a picture showed him reappearing in the streets of Gotham. Kate claims that the photo is fake because it’s too grainy to tell what exactly it is. Tommy lets Kate know he finds her lack of a reaction to Batman’s return shocking. After all, as Tommy points out, Batman did let Kate’s mother and sister die and is surprised she isn't more upset. Kate says that she had years to process, noting that Batman also saved Tommy's mother. Changing the subject, Tommy tells her that he wanted to invite Bruce to celebrate his new acquisition, and insists that he's there. Kate says that he isn't, but agrees to leave the invitation on Bruce's desk. Luke then calls Kate to tell her that something of value has been stolen from one of Wayne Tower’s secret weapons facilities. The security cameras were jammed, but he thinks it could have been Alice and her gang. On her way there, she passes the Gotham Gazette, where cops have been called since someone wrote, “Come out, come out Batman!” in red painting, and there’s an effigy wearing batman’s outfit was drenched in what looks like “blood”. Kate witnesses this and writes to Bruce, about how in trying to be Batman, she ended up drawing out his enemies instead. She tells her cousin that she figures today is just an effigy. But she wonders what will happen when his enemies start to kill real people in order to draw him out. She confesses that the Gotham he set out to protect is now less safe because of her actions thus far.

In the Batcave, Luke shows Kate how the Batsuit is bulletproof. He explains to her that the thieves took a prototype railgun from Wayne R&D. The gun is a parallel conductor that generates a pulse of electromagnetism, thus accelerating the velocity of the projectile. It’s the most lethal weapon that Bruce ever built. Luke then tells Kate that the one he was using is just a prototype used for showing Kate what the rail gun does. Luke goes onto say that it is the only gun that shoots a shot strong enough to penetrate the suit. Bruce had it built in case the suit ever fell into the wrong hands. Thus, whoever is in possession of the gun has the only gun out there that can kill Batman. However, the disruptor in Kate's gauntlet can neutralize the gun. When trying to pinpoint who could have taken it, Luke suggests that maybe Alice took the gun, but Kate suspects that Tommy Elliot might be behind it instead. She shows Luke the invitation and notes that it was for Bruce rather than her. Kate figures Tommy knows Bruce is Batman and that's why he stole the gun. Luke suggests that she put the Batsuit back on and show Tommy that Batman isn't afraid of him. He figures that Bruce built something to stop the rail gun and he'll find it, and Kate should defeat the thief. Kate warns him that if she doesn't, then she'll let down the entire city.

Kate arrives at the Elliot party and presents her invitation to get in. She gets into the elevator with Mary and Sophie. Sophie explains why she's there with Mary; explaining she’s her security detail. Kate mouths an "I’m sorry" to Mary, to which Mary mouths back that she knows. Sophie then asks Kate why she's at the party, and Kate says that she was told to move on. They all go up to the top floor and Kate looks around for Tommy. The bartender Reagan advises her to stay at the bar and wait for Tommy here if she wants to save herself from a verbal car wash of veiled misogyny. Reagan promises that Tommy will be here, so Kate orders a beer. Tyler comes over shortly after, and in talking with Tyler, Kate realizes that Sophie hasn’t told him that the two of them dated or that Sophie is into women. When Tyler leaves, Kate is impressed when Reagan talks about how Tyler married Kate’s ex and he has no idea. Reagan explains that she since she started bartending before she could drink, she has become quite good at reading people. At one point, Jacob says to Kate that he is glad to have someone around who hates Tommy Elliot more than he does, even if he is one of his biggest clients for the Crows.

Kate eventually finds Tommy, who says that even though it took him half his life, he's finally looking down on Bruce. Kate asks why he thinks Bruce is there, and Tommy says that they're "cosmic besties". Kate casually mentions that a thief stole the rail gun and there's a hidden GPS hidden in the butt, and Wayne Security will soon track down the thief. Tommy is subsequently busted by Kate when she sees him inspecting the stolen gun, looking for the supposed GPS. She tells him that it isn't his and asks how he knows Bruce is Batman. Tommy explains that he paid a man to riddle him the answer, and says that since Bruce saved his mother, he didn't get his inheritance earlier and his mother went mad. He says that he's going to get revenge on the city's hero, and insists that Batman has to die. Tommy draws a gun and aims it at Kate, then takes out a phone and shuts down the power throughout the building. Tommy tells Kate to have Batman meet him on the roof or he drops the elevators. Kate says that Batman isn't in Gotham, and Tommy releases an elevator with catering staff in it and says that in an hour, he'll do it to people the city will actually miss if Batman doesn't meet him. Kate checks out the elevator crash site and finds the survivors. She tells one that he's going to be okay as the EMTs arrive.

Kate then goes to the Batcave and says how this is all her fault, and asks Luke if he really thinks Bruce is coming back. Luke admits that he doesn't think so, and Kate says that maybe she's better than Batman because at least she's there. Luke fixes the suit by painting the bat symbol red for Kate’s Batwoman suit. Tommy is waiting on the roof as Batwoman moves through the shadows. She finally steps out and when Tommy realizes that she's not Batman, she tells him that's the whole point. Tommy demands Batman, and calls her Batman’s side piece. Luke tells her to activate the neutralizer in her glove. She does but it doesn't work, and Luke activates it remotely, but tells to stall for 30 seconds while it charges. Batwoman attacks Tommy and the two of them fight. He grabs the gun just as the neutralizer charges, and Batwoman shuts down the rail gun. However, Tommy grabs his remote and sets off a charge. The elevator containing Catherine and Jacob shakes as the cable holding it up breaks. Batwoman drops down, standing on another elevator, and uses the two-way grappling gun to catch it. Tommy sets off the charge on the elevator Batwoman is on. She uses a grappling hook to pull herself up. She is holding for her life, and Tommy steps on her hands. He tells her to let go, but is knocked out by Alice from behind. Kate pulls herself up and points out that Alice just saved her life. Alice says that they're even now, but proceeds to stroke Kate's cheek, and notes that the red wig must be homage to the color of their birthstone. Kate says it's also to remind them where they came from. After a moment, Alice tells Kate that she couldn’t wait 24 hours and figures Dodgson will die now because she couldn’t stop herself from killing. Kate wonders why she saved her, and Alice says that it’s because she has plans for her. When Kate grabs her and says that if she kills again she'll stop thinking of Alice as her sister, Alice says that's what she wants. Kate doesn't believe it, and Alice pulls Kate's hand away and leaves.

As the police take Tommy away, Kate arrives and Tommy tells her to tell Bruce that he won't stop until Bruce shows his face. Kate reveals that they are taking him to Arkham Asylum, and taunts him by wishing him good luck buying his way out of that punishment. Reagan then is seen coming out and Kate asks her if she's okay. She reveals that she came over to ask her if she’s into her and promises to call Kate when the former says yes.

In another letter to Bruce, Kate admits that she was afraid of letting him down, and figures that whatever happens is worth it. She later stands on top of Wayne Enterprises in her new suit, where a helicopter spots her.

Taking charge of Wayne Enterprises
Kate became known as "Batwoman", a vigilante who fights for Gotham after the disappearance of the Batman. She also took charge of Wayne Enterprises, planning to redevelop it into a real-estate development firm.

Meeting other heroes
At some point after reality was altered, Batwoman stood on the top of Wayne Enterprises.

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.

Arkham breakout
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 walked 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.

Possible future
Batwoman may be involved in the Crisis of 2019, along with the Flash, Supergirl, White Canary, and other heroes.

Erased future
When the Crisis of 2019 originally took place on April 25, 2024, 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
"So I have this thing with rules."
 * -|As a civilian=

- Kate Kane to Luke Fox

Similar to her cousin, Bruce Wayne, Kate is a no-nonsense and blunt individual. She is very open with her personal opinion.

As Batwoman, Kate is very stoic and committed to helping Gotham City. While mostly an antisocial individual, she can give respect to those she thinks deserves it, as she acknowledged Supergirl's worth as a hero.

Abilities
"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."
 * Expert driver: Kate rides a motorcycle.

- Kate Kane to Kara Danvers

"My cousin figured it out years ago. Be more terrifying than your enemy."
 * Indomitable will/High tolerance for pain: Kate has a high threshold for pain; she showed no discomfort when she received stitches on her shoulder.

- Kate Kane to Luke Fox

"I'd spent years traveling the world, training with combat and survivalist specialists so I could join the Crows."
 * 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/businesswoman: Kate is very intelligent; despite her part-time vigilantism, she manages the big company Wayne Enterprises without any perceivable difficulty. Alice called her "clever".
 * Expert investigator: Kate is a very perceptive individual; she was able to quickly determine that Supergirl is Kara Danvers. She thought to access Wayne Enterprises' security camera feed, which was not included in the Crows Security network. She is also observant of small details; she recognized the miniscule writing on a paddle held by one of Alice's henchmen, which allowed her to locate her whereabouts.
 * Expert of deception: Kate is very good at keeping her own identity as Batwoman a secret; both the highly intelligent Green Arrow, Flash and Supergirl were unable to deduce her alter-ego; Supergirl had to resort to using her x-ray vision to discover who Batwoman is.

- Kate Kane

"She really is like Batman."
 * 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. Cisco Ramon referred to Kate as "badass" only moments after witnessing her in action, and Supergirl even stated that the two of them would make a good team, not dissimilar to their cousins' relationship. Before becoming Batwoman, Kate easily defeated several of Alice's henchmen and even made use of her environment to fight them off, i.e. weaponizing a fire extinguisher, frying pan and a door.
 * 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. She also accurately threw one to knock Alice's remote off a building.

- Caitlin Snow


 * Peak of human physical condition: As a vigilante and former member of the Point Rock Academy, 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. She was strong enough to punch through the ice from underwater, and kick open the boarded-up doors to Bruce Wayne's office. Kate has a high level of stamina, as she was capable of holding her breath for a long period of time underwater.
