Her father led a rescue mission, which saved Kate's life. Colonel Kane shot the men who were about to kill Kate. However, her sister and mother were killed in the attempt.

Batman vs. Robin[]

Kate made a small appearance in her Batwoman costume as one of the fallen bodies next to Damian Wayne's Batman in Bruce's hallucination by the Court of Owls.

Batman: Bad Blood[]

A few months after Talon laid siege to Wayne Manor, a turf war erupted between the Black Mask mob and a new rival gang composed of costumed supervillains. The gang kidnapped Chuckie Sol, one of Black Mask's Made Men, and interrogated him for information on an incoming weapons shipment. Batwoman then intervened and bounced a Batarang filled with smoke off of Electrocutioner. She dispatched some armed men with her handgun and combat skills. She held her own against Electrocutioner and Hellhound, until Tusk knocked her to the ground. Suddenly, Batman stepped in and lectured her on the ramifications of dressing like a bat, and then ordered her to leave. However, she continued fighting Hellhound until Killer Moth dispensed several moth drones. Batwoman shot two of them down, but her clip ran out. As she ran off, the drone latched onto her back and flew her into the warehouse nearby. She reloaded and blasted the drone point blank and fell onto the rafters. Firefly then arrived and tossed out grenade canisters, but Batman tackled her out of the way and disabled Firefly with two Batarangs.

Batman and Batwoman soon encountered the Heretic and Onyx. Batwoman was no match for him as he grabbed her by the head and tossed her into the guardrail. Batman held his own against Heretic, where Batwoman jumped him, until Heretic threw her over the rafters. Batman snagged her leg with a grapnel line. On Heretic's orders, Onyx threw several knives into Batman and triggered explosives. Batman swung Batwoman out the warehouse, into the dock waters outside. She then resurfaced and saw the warehouse in ruins. For the next two weeks, Batwoman tried in vain to identify and find any information on the Heretic, but she needed help. Kane met with her father at a cafe for dinner and caught him pouring liquor into his drink, despite doctor's orders to give it up. She was convinced Batman died and shared a rendering she did of Heretic. Colonel Kane agreed to reach out to his network and look into the Heretic. They noticed the Bat-Signal in the night sky as Kane implied that maybe Batwoman should answer the call, but she declined, claiming it was not her style. She was then shocked to see the Batmobile pass by the cafe and left to chase it.

Batwoman followed the Batmobile all night, in order to verify her conclusions about Batman. She was lured into an alley, where Batman and Robin confronted her. She quickly deduced that Batman was really Nightwing, much to Robin's delight. She then revealed witnessing Batman's death and retraced the battle at the ruins of the warehouse, but Robin didn't believe her. Nightwing/Batman proposed they should work together, but Batwoman had no interest in joining their "cult." She took off and glided back to the city. Alfred Pennyworth found Batman's video file on Batwoman and shared it with Dick Grayson and Robin/Damian Wayne. Pennyworth and Grayson were surprised and dismayed to learn that Batwoman was Kane, another motivated by tragedy. The next night, Batwoman met with her father in a park. He briefed her on the Heretic and his activity in the last ten months forming a team of supervillains from Gotham's underworld. Batwoman didn't get what she needed and apologized. She left to figure things out on her own.

The next night, she went out to a bar to clear her head. Kane struck up a conversation with Renee Montoya and laughed for the first time in a long while. After a drunk woman brushed past Montoya to order more drinks, Kane noticed her holstered gun and asked if she was a cop. Montoya stated she was a detective. Kane had a hard time believing someone as hot as she was a cop then realized she said that out loud. Montoya was amused. Kane downplayed herself and revealed she hadn't dated in over a year. She suddenly received an anonymous text to meet on the rooftop across the street. Kane sighted Batman. Kane gave Montoya her card and admitted to really liking her. Batman called her by "Katey" to her surprise. He admitted not knowing long but the actual Batman knew from the start. Batwoman insisted she hadn't given up on the case. Batman agreed they all needed to take off their masks once in a while. He revealed his secret identity to her. She immediately recognized him as Dick Grayson. Grayson admitted to having a crush on her after seeing her at the society bashes. Kane admitted she thought he was totally annoying.

Batwoman told Grayson about the night Batman saved her life. Grayson understood her drive but believed she didn't have to be alone. Batwoman then asked what it was like growing up with Batman. Grayson admitted as a child he idolized Batman and wanted to be him, but as he got older, he realized Batman wore a lot of masks and there was just pain behind them. A pain he wouldn't share. Alfred Pennyworth alerted Grayson of Robin's sudden disappearance. Batwoman was surprised the butler was involved, too. Luckily, Pennyworth placed a tracker in Robin's suit. Batman and Batwoman followed the tracker to the Sisters of Perpetual Grace convent outside of Gotham. Somehow, he convinced her to switch to rubber bullets. They were met by nuns armed with M-60s and katanas. Killer Moth and Firefly appeared but were shot out of the sky by Batwing. After Batwing breached the front doors, Onyx attacked Batwoman. She took the fight to the bell tower. Onyx got Batwoman in a choke hold but she flipped Onyx over the edge of the tower as the structure began to collapse due to Killer Moth and Firefly's pursuit of Batwing.

Bruce Wayne was freed but he only ordered Nightwing and Robin back to the city without so much of a thank you to Batwing or Batwoman. Batwoman took the hard drive recovered from the convent but was unable to access it. She turned it over to Batwing. A week after the battle, Wayne wasn’t happy to hear she had the drive and ordered her off the case when she was done with it. Grayson broke the news to her but she revealed to him the drive was with Batwing. He tried to apologize but Kane said there was nothing to apologize for. She turned off the TV and saw her father aiming his gun right at her. She ran to the kitchen and kicked a cart into him. She tossed a frying pan and knocked his gun away. He pulled a knife but she, in turn, punched him then stabbed his right wrist with a butter knife. She finally knocked him out with a pan. When he came to, the Colonel had no memory of what happened. Batwoman met with Nightwing and Robin and told them about what happened. They realized Bruce Wayne told Talia about the hard drive.

Nightwing, Robin, Batwoman, and Batwing flew to the World Tech Summit and infiltrated the Watchtower Initiative but were soon discovered by Firefly. Talia demanded Robin join her or die. The two sides clashed. Batwoman briefly fought Tusk then took on Talia one-on-one. Batwing and Firefly's battle outside damaged one of the thrusters and the Watchtower drifted into the city. As it brushed past a building, Batwoman seemingly perished. Talia left the scene to catch up with Batman. Batwoman dangled outside and made her way back inside. After Batman broke through his programming and saved Nightwing by shooting the sword out of Talia's hands, Batwoman rushed in and decked her for Colonel Kane. They watched as Talia made her escape aboard a transport only to crash into the waters outside Gotham. Back home, Kane relayed to her father that the brainwashing he endured was broken for good. He admitted he was proud of her and so would Gabrielle and Elizabeth be. Kane got up to answer the door. Renee Montoya mused she came too early. Colonel Kane invited her inside. Sometime later, Batwoman caught up to Nightwing on her motorcycle as they headed to the Gotham City Police Department headquarters to meet with Batman and Robin on the roof. Batwing flew past them both. Atop the roof, they noticed the Penguin was being chased by police cars. They joined in.

The Death of Superman[]

Kate makes a cameo attending the funeral of Superman, who'd died fighting Doomsday, sitting next to Maggie Sawyer.

Justice League Dark: Apokolips War[]

Two years after the defeat of the Justice League with multiple members of the Teen Titans killed and the beginning of Darkseid's tyranny over Earth, Batwoman appears as part of the group tasked with destroying one of the Reaper devices attached to the Earth's surface, alongside Batgirl, Batwing and Black Orchid. Despite the group's valiant efforts, Batwoman is dragged off-screen by a Parademon and is presumed to have been killed. After Darkseid was defeated, The Flash entered the Speed Force to create a second Flashpoint and erasing the timeline.

Batwoman and Batgirl


  • Peak human condition: Kate has trained her body to be at the physical peak in order to combat crime. As such, she’s able to take blows to a certain extent, being able to take an uppercut to the jaw by someone with enhanced strength and survive. However, she isn't on Batman's level
  • Expert combatant: As a former military officer, Kate has received standard combat training. It’s unknown to what extent, but she has shown advanced skill, defeating multiple criminals in unarmed combat.

As Batwoman, she's snarky, but is almost always able to keep a calm demeanor. Kate and her father get along extremely well, with him serving as her main support system.

Kate believes God is a woman. When Batwing quipped God wouldn't like them breaking into a place of worship, Kate returned with the quip "I don't think she's been here in a long time." She seems to also be trying to romance Renee Montoya.


  • Motorcycle
  • Guns: Unlike most members of the Bat-Family, Kate utilizes firearms, carrying two red pistols in her arsenal. Originally, she used real bullets, but at Dick's behest, switched to using rubber bullets to maintain Batman's "no-kill" policy. It’s unknown if she switched back to regular bullets. She used them during her fight against Talia and during the rescue of Batman
