Kate Kane (portrayed by Ruby Rose; main: season 1 and^[1][2] Wallis Day; recurring: season 2),^[3] Gracyn Shinyei as a child) is an out lesbian and the cousin of Bruce Wayne who, armed with a fierce passion for social justice and a flair for speaking her mind, dedicates herself to defending Gotham in Batman's absence as Batwoman.

In season two, the airplane that Kate is coming in from National City crashes. While an ex-con named Ryan Wilder finds the Batsuit, Kate's body is nowhere to be found which affects everyone that knows her in a different way. In a newspaper article talking about Kate's disappearance, Safiyah Sohail sent a message to Alice quoting "Consider us even". When Alice was brought to Coryana, Safiyah denied any knowledge of blowing up Kate's airplane and has proof that she is still alive in the form of Kate's necklace. Upon obtaining Kate's salvaged cellphone, Jacob has the tech guys work to unlock it. By the time Sophie returns, Jacob finds a portrait that has Safiyah's name defacing it and the fact that the portrait was made by Jack Napier. It is then discovered that Kate is still alive and in the sewers where she has a bandaged face. This is because the False Face Society ambushed her on her plane where her face received burns when trying to abduct her and her larynx was damaged enough to alter her voice. Making her loved ones believe she is dead, Black Mask has Enigma work on Kate as Enigma takes her necklace. Enigma makes Kate think she is Roman Sionis' daughter Circe while placing a mask on her burnt face. "Circe" confronts Batwoman and Alice at a boat following Ocean and Angelique's escape and overpowers them, though Batwoman leaves Alice for "Circe". She brings Alice to Black Mask who decides not to kill her. He then orders "Circe" to take Alice downstairs to be tortured. Alice manages to save herself only by offering to craft a new face for "Circe" while noting that she was there when Circe was killed during the Arkham breakout. However, this causes her to realize that "Circe" has the same eyes as her sister as the real Circe had brown eyes.

After telling Jacob about Kate's current state, he and Alice break into the Sionis residence and take "Circe" to the abandoned Crow's headquarters where they confirm she is Kate Kane. Upon obtaining "Circe" and getting DNA printing, Jacob and Alice use some items to cause Kate to remember some things prior to Tatiana and some False Face Society members attacking. Ryan finds her and brings her to Wayne Tower. Mary had to sedate her when Kate experiences a mental battle between her younger self and "Circe". Upon pulling off a trick with Sophie, "Circe" confronts Black Mask where she stabs him in the hand wanting to know why she has Kate's memories. "Circe" fools Luke, Sophie, and Mary by having them think that Kate is in control so that she can access the other parts of the Batcave. After a fight with Ryan, "Circe" makes off with the villain items and gives them to Black Mask while "Circe" rips apart the Batwoman suit. During a showdown at a bridge, Ryan and Alice use the vapors of the Snakebite on "Circe" where she and Alice fall into the river. The vapors and being resuscitated by Ryan purge the "Circe" persona from Kate. After giving Ryan her blessing to continue as Batwoman, Kate leaves Gotham City stating to Sophie that she is going to visit her father and Supergirl before going on a quest to find Bruce.

Ryan Wilder (portrayed by Javicia Leslie; seasons 2–3; Ava Augustin as a child) is Kate Kane's successor as Batwoman, who was nicknamed "Batwoman 2.0" by Vesper Fairchild.^[4] She is a highly skilled yet undisciplined fighter who spent 18 months in prison after two Crows operatives caught her with the drugs that Angelique Martin had in her possession. While her parole officer Susan Stevens expects her to maintain the conditions of her parole, Ryan was living out of her van with her plant and becomes the new Batwoman after finding the Batsuit in the wreckage of an airplane that Kate was coming in from National City. One of her plans to use the Batsuit is to go after Alice who had connections with the squatters that killed her adoptive mom Cora Lewis and the building's landlord. In a scuffle with Tommy Elliot, Ryan gets shot with the Kryptonite meant for Kate. This gives her a wound that is getting worse over time as noted by Mary. Despite Alice burning the Desert Rose crops, it turned out that Julia managed to find a Desert Rose to use on Ryan where it turns out to be Ryan's plant that just bloomed. After being cured and the news about Kate's "death" being confirmed, Ryan starts to work on getting Angelique out of the False Face Society leading to an encounter with Black Mask. Ryan later had a final duel with "Circe" with Alice's help which led to Ryan using the vapors from the Snakebite to purge the "Circe" persona from Kate and even resuscitating her after Alice pulled Kate from the river. Thanks to Susan, the parole board releases Ryan from parole as Ryan receives Kate's blessing to continue as Batwoman. Then Ryan pitches to Luke and Mary to open a community center over Mary's clinic to make it official.

In season three, Ryan is blackmailed by former GCPD detective Renee Montoya to find the missing Batman villain items that fell into the river, while also learning that her birth mother is successful businesswoman Jada Jet, who initially rejects her in favor of her son, Marquis, though Marquis shows an interest in working with Ryan to bring the family closer. As Ryan recovers Batman's trophies, she later discovers that Marquis is suffering from psychopathic tendencies due to brain damage inflicted on him by the Joker as a child with his joy buzzer, shown when he brutally beats and kills an assassin sent to murder Jada. Jada later confides to Ryan that Marquis killed his own father as a joke, which she covered up, and actually had Ryan given away to protect her from Marquis, only learning later that the midwife she had paid to cover it up actually abandoned Ryan beside a shop and kept the two million dollars meant to fund her education for himself. Ryan later finds out that the joy buzzer is the only thing that can restore Marquis's sanity, and that Montoya is actually holding it in her possession in exchange for Ryan freeing Poison Ivy from underneath Gotham, where Batman had previously buried her to stop her from exterminating Gotham's population. As Marquis takes over Wayne Enterprises, Ryan reluctantly helps free Ivy and acquires the joy buzzer, attracting the attention of Alice, who wants to use it to restore her own sanity as well. Ryan manages to defeat Ivy and strip her of her powers with help from Mary and Montoya when she decides to continue her plans to destroy Gotham, and the mayor orders both Montoya and Ivy to leave Gotham forever. As Marquis loses more of his sanity, he eventually plans to unleash bombs of Joker's toxic gas all over Gotham, but he is foiled when Ryan defeats him and uses the joy buzzer on him with help from Alice, who decides to leave Gotham to seek rehabilitation elsewhere. Ryan later starts a relationship with Sophie Moore and mends her relationships with both Jada and Marquis, unaware that the chemicals released from the Joker gas canisters during the blimp crash have created and unleashed a radioactive creature.

Elizabeth "Beth" Kane / Alice (portrayed by Rachel Skarsten; seasons 1–3; Ava Sleeth as a child) is Kate's presumed-dead twin sister and the leader of the Wonderland Gang whose personality goes from maniacal to charming and back again as she sets out to erode Gotham's sense of security.^[5]

Beth Kane was presumed dead after a car accident, but her body was never recovered. What really happened is that she was rescued from drowning and subsequently being held captive by August Cartwright who wants her to be a companion for his disfigured son Jonathan "Mouse" Cartwright. In addition, Jacob Kane's wife Catherine Hamilton-Kane used DNA analysts and the skull fragments of a deer to make Jacob think that Beth is dead. At a later date, she even received bad treatment from August's mother Mabel who she referred to as the Queen of Hearts. After discovering her mother's decapacitated head in August's freezer Beth would later kill Mabel for taking her mother's earrings, snapping over the years of abuse, imprisonment, and mental torture, starting a house fire leading to her escape and August's disappearance shortly afterwards. At some point after escaping from August, Beth hid on a boat where she was found during a raid by Safiyah Sohail who trained her. Due to Beth falling for Ocean who wanted to make more use of the Desert Rose, Safiyah had their memories of each other suppressed by Enigma. When Beth returned to Gotham and took a sample of the Desert Rose with her, she incurred the wrath of Safiyah.

In season two, Alice starts to check up on Tommy at Wayne Manor while angered about Kate's apparent death in the plane crash. When Jacob visits Wayne Manor due to Tommy as Bruce mentioned that Alice was sighted there, Alice rants about Jacob having to remarry and admits to Jacob that Kate is Batwoman advising him to compare the two facts about them. While walking in the sewers, a newspaper talking about Kate's disappearance lands near Alice with a message from Safiyah Sohail stating, "Consider us even". Alice states to Mouse's corpse that there is a war coming to Gotham City and that Batwoman won't be around to stop it. Tying a rat to Mouse's corpse, Alice attracts a lot of bats to feed off it which causes them to carry a poison when attacking a Batwoman rally. When Sophie finds where Alice is hiding, both of them are taken captive by Tatiana. When brought to Coryana where Alice confronts her, Safiyah denies any knowledge of blowing up the airplane that Kate was in while also having proof that she's still alive by showing her necklace. Before returning Alice to Gotham, Safiyah wants her to do an unspecified assignment. This was to target Ocean. When they reunite, Alice and Ocean start to experience suppressed memories of their time on Coryana. After fighting off the assassins sent by Safiyah, Alice and Ocean drive off. When Alice brings a white tube from the back seat to her, Ocean asks if she has ever heard of Jack Napier. Alice uses a look-alike of Ocean to fool Tatiana that she killed him. Due to Ryan exposing the truth, Safiyah had the real Ocean brought to her and ordered Alice to use the knife on him. Alice reluctantly does so. When she found that Safiyah lied to her, Alice is removed from Safiyah's lair where she kills the men assigned to that job and later burns the Desert Rose crops. After a talk with a hallucination of a younger Kate, Alice plans to find a way to forget her and tries to with help from Enigma until Ocean crashes it. Enigma gets away by saying "Mockingbird Anew" which restores their memories. When Ocean gets abducted by the False Face Society, Alice works with Batwoman to rescue him and Angelique after torturing one of the members. Once that was done, Alice and Batwoman are attacked by a brainwash Kate Kane who believes she is Circe Sionis. Both of them are overpowered as Batwoman leaves Alice for her. "Circe" brings Alice to Black Mask who notes her history of leading the now-defunct Wonderland Gang and decides not to kill. He instead instructs "Circe" to take Alice down to the basement. "Circe" tortured Alice about the information revolving around who the new Batwoman is. She told Alice she would reveal it if Black Mask was present. When that was done, Alice does reveal to Black Mask her knowledge that he is Roman Sionis and that she knew Circe before she was killed in the Arkham breakout. Alice offered to make "Circe" a new face which Black Mask complied to. When Black Mask when to get a cosmetic, Alice tried the face on "Circe" where she notes that the real Circe had brown eyes and this "Circe" had blue eyes. When the face was on "Circe", Alice finds out that "Circe" is actually Kate. After Black Mask dismissed Alice while advising her to keep quiet about what happened here or else, Alice went back to Enigma's office and suspended her from the ceiling in order to get answers on how to break Kate's brainwashing. Enigma told her to get something that belonged to Kate. When Alice gets the keys to Kate's motorcycle, Enigma told her that it requires a password to fully undo the brainwashing as Enigma's neck is snapped by Ocean much to Alice's dismay where Ocean states that Kate will only put Alice back in Arkham Asylum. After Ocean disposed of Enigma's body, Alice confronts Jacob in his car stating that she found Kate alive. They managed to cause some of Kate's memories to return before being attacked by Tatiana and some False Face Society members. When in Safiyah's clutches, Alice sees the news detailing Jacob's arrest and the confirmation that Beth Kane is Alice. Batwoman was able to secure Alice's release by giving her plant to Safiyah. However, Alice later finds Ocean dead after killing Tatiana outside her hideout. Following a visit from Mary, Alice has Ocean's body cremated and dumped into the ocean as Safiyah appears to pay some respect to Ocean's death. After Safiyah mentions how Black Mask will have procured Poison Ivy's plant through Circe and how she will grant Alice a sanctuary on Coryana, Alice stabs Safiyah with the same knife used on Ocean stating that she will remove it when she regains what she lost. During a showdown with Black Mask where he mentioned that he's a good villain, Alice states that Joker is worse than him, uses one of Joker's acid flower spray on his face, and slams the mask on Roman's face. Then she catches up to Ryan where she helps to use the Snakebite vapor on "Circe" prior to Alice falling into the river with her. She gets Kate out of the river and helps Ryan resuscitate her before being taken away by the approaching police officers. When visited by Ryan in Arkham Asylum, Alice rants about Black Mask being her noisy neighbor and reveals to Ryan that her biological mother is still alive. In the ultimate series finale she leaves Gotham to rediscover herself as Beth after gaining an sisterly relationship with Mary during Season 3.

• Skarsten also portrayed an alternate version of Beth who was displaced from her native Earth during "Crisis on Infinite Earths" and appeared on Earth-Prime. This version was saved by Kate and did not get lost during the car accident. She is later sniped by August Cartwright, mistaking her for Alice.

Sophie Moore (portrayed by Meagan Tandy; seasons 1–3) is a military academy graduate turned high-level Crows agent and Kate's estranged ex-girlfriend. When they were both threatened expulsion, Sophie decided to sign an agreement denying her sexuality, fearing rejection from everyone including her mother and led to her and Kate's break-up, since Kate wasn't afraid of judgment of being herself.

In season two, Mary's clinic was shut down by Jacob following the incident with Amygdala. though Mary will not allow this to happen and finds a way to keep it open. Jacob allows the clinic to remain open after she treated his Snakebite drug and he helps to tend to those who have been given zombie personalities by the latest Snakebite drug. Upon the revelation that Black Mask had Enigma brainwash Kate into being Circe Sionis, Mary did use a sedative on her as she notes that Kate and "Circe" are fighting for control of Kate's body. Following Jacob's arrest, Mary gets a call from him stating that he is being transferred to a prison in Metropolis and to avoid getting targeted by the False Face Society. Her clinic comes in handy during the riots instigated by Black Mask and she figured out that the Snakebite found on Russell Tavaroff's body can be converted into a vapor to free Kate from the "Circe" persona.

In season three, Mary gets ensnared by Poison Ivy's vine. She starts to place plants in her clinic with one of them helping in the thawing of Jordan Moore. It is then revealed that Mary was infected by the plant that caused her to be corrupted and become a new Poison Ivy that's referred to as Poison Mary when exposed to sunlight, where she attacked Chris Hayner and trapped Virgil Getty. Under this control, Mary was able to steal the Batwing component that contained the Lucius Fox A.I. to make use of it during the confrontation at the botanical gardens. After getting away, Mary drives off with Alice to another location, the pair becoming lovers. After Batwoman's attempt to cure her, Mary changes her appearance where she sports a copy of Poison Ivy's outfit. Alice has called this form "Poison Mary". When Poison Mary infiltrated Marquis Jet's party, she revealed some secrets about Batwoman which led to him taking a disguised Luke captive. During a confrontation on the roof, Poison Mary escapes when Marquis was hit by the desiccation formula that was supposed to be used on Poison Mary. After mind-controlling Alice to sleep, Poison Mary makes her way to where Poison Ivy is. They then end up in an embrace that brings Poison Ivy back to full power.

In season two, Luke helps out Ryan Wilder when she becomes the current Batwoman following Kate's disappearance. When Luke was shot by Russell Tavaroff and Wolf Spider secretly administers the Desert Rose serum, Luke ends up in a purgatory state where he sees his father looking out the window as a subconscious form of Bruce Wayne advises him to either live or die. Regardless, Luke awakens from his coma. When Tavaroff made bail, Luke encountered him at a bar where he partook in a poker game that John Diggle was involved him. Afterwards, Tavaroff tried to attack him outside the bar only for Diggle to fight him off. Then Luke and Diggle compared how they lost their fathers as Diggle advises him to take the right path as the Bat-Signal gives off a Morse code. Luke later takes on the Batwing mantle where he saves Mary from a powered Russell Tavaroff.

In season three, Luke works to improve the Batwing costume where he meets the A.I. version of his father within it. When Mary becomes Poison Mary, she steals the Lucius Fox A.I. from the Batwing suit and gives it to Marquis. Luke managed to reclaim the A.I. when he and Sophie infiltrate Wayne Enterprises.

In season two, Jacob becomes affected by Kate's apparent death in a plane crash. He finds Tommy in the form of Bruce who claims that he's helping to find Kate while mentioning that Alice was sighted at Wayne Manor. When Jacob goes there and finds Alice, she mentions that Kate is Batwoman and that he should compare the facts about them. Jacob later removes the "do not cross" tape around the Bat-Signal and shines it in sadness. After having the tech guys unlock Kate's salvaged cellphone upon Sophie's return, Jacob sees the picture of a portrait with Safiyah's name defacing it. Jacob then notices that the portrait is by Jack Napier. This leads to him trying to obtain the portrait when it turns out that it can lead him to Coryana. When he does claim it after his vehicle strikes Wolf Spider, it was later mentioned by Sophie that the portrait was a fake much to the dismay of the Crows. Jacob even learned about some other dark secrets about Catherine like the experiments to cure Aaron Helzinger to research on the Desert Rose much to his dismay. Jacob later gets hooked on Snakebite due to the orchestrated plots of Black Mask which enables Jacob to relive his past like hallucinating that he rescued Beth. In his latest hallucination, Jacob passed out and was brought to Mary's clinic after being found by two homeless people. Mary treated him and learned how Jacob came in contact with the Snakebite drug. He does help Mary treat those who were starting to develop zombie-like personalities from the new Snakebite drug. After a talk with Sophie Moore regarding Luke Fox getting shot, Jacob advises Russell Tavaroff to hand in his gear and go on suspension until further notice. Tavaroff then knocks out Jacob and plans to dispose of him with the Snakebite drug. Jacob is saved by Batwoman who defeats Tavaroff and those involved. After being advised to "burn it down", Jacob exposes the truth about what happened the night when Luke Fox was shot and states that Crows Security is shutting down. Sophie commends him on this action. While in the parking lot, Jacob is confronted by Alice who states that Kate is alive. They managed to cause Kate to remember some memories before getting attacked by Tatiana and the False Face Society. Jacob is brought to Roman Sionis where Jacob acknowledged learning that Roman and Black Mask are one and the same. As three of the False Face Society members are actually police officers who are secretly on Sionis' side, Sionis advised Jacob to keep quiet or else his remaining family will be eliminated. Jacob is arrested by those police officers for withholding information about Alice being Beth Kane. News of Jacob's arrest reached every news outlet. On TV while being taken into GCPD HQ, Jacob stated that Beth became Alice due to the bad people twisting her childhood and for all parents to think about their children. Thanks to a deal, Jacob informs Mary that he is being transferred to a prison in Metropolis and advises her to stay off the False Face Society's radar. After Black Mask is defeated, Kate plans to visit her father before going to visit Supergirl and search for Bruce.

Catherine Hamilton-Kane (portrayed by Elizabeth Anweis; season 1) is Mary's mom, Kate's stepmother, Jacob's second wife and one of Gotham's most powerful citizens who made her fortune as a defense contractor and the CEO of Hamilton Dynamics.^[8] After marrying Jacob, Catherine faked Beth's death by bribing DNA analysts in an attempt to help him and Kate move on, leading to everyone giving up the search and leaving Beth at the mercy of August. When realizing that Beth might be Alice, Catherine desperately tried to hide the truth by making several attempts on Alice's life. As revenge for the pain Catherine caused her, Alice manipulated events that caused her to reveal to her deception of Beth's death to Jacob, resulting in a file for divorce and confess her corrupt ways upon the Wonderland Gang's infiltration of an event, where Catherine starts to collapse from the poison that was placed in her drink. As she was dying, Alice provided a cure only after Catherine apologized for the years of suffering, she unintentionally put her through. But when its revealed Mary was also poisoned, Catherine sacrifices her life to allow Mary to live. Before passing away, Catherine states that she knew of Mary's clinic and is proud of her. At the time when the complications of both versions of Beth Kane being on Earth-Prime start to worsen, Alice hallucinates seeing Catherine's ghost.

Season two revealed some of Catherine's other experiments like working to cure Aaron Helzinger to research on the Desert Rose which also earned Catherine the hatred of Safiyah Sohail and the dismay of Jacob.

In her earlier life, Renee had a history with Pamela Isley prior to being experimented on by Mark LeGrand. To stop Poison Ivy, Renee had to enlist Batman to create a desiccation formula that would disable Poison Ivy. It worked as Renee had Batman hide Poison Ivy's body.

She is first seen when investigating the actions committed by the second Mad Hatter. Renee later talks to Mayor Hartley stating that the Mad Hatter is not the one that fought Batman and to hear her out before Gotham City becomes "Jim Gordon's version" again. She later meets Batwoman and voices her knowledge of her being Ryan Wilder due to a deal that Alice cut with her. Batwoman had to comply with Renee's offer that involved Alice being a work release consultant in the stolen Batman trophies - a mission she knew they could never complete because she herself had the last one (Joker's buzzer). Her real goal was for Batwoman and Alice, in the process of tracking down the trophies, to eventually discover where Batman buried Pamela Isley, so that she could free the love of her life. While helping to examine a whip to make sure it's not Catwoman's whip, Alice learned that Renee had a large classified file on Poison Ivy and her being experimented on by Mark LeGrand by subjecting her to oleander, nightshade, and water hemlock. Poison Ivy's activities led to Renee advising Batman to bury her alive. After being displeased at Batwoman and Batwing for withholding the information that one of Poison Ivy's plants infected Mary, Renee speaks with Sophie at the bar as they make out in Renee's apartment. When it came to the desiccation formula to use on Poison Mary, Renee accompanied Batwoman and Sophie into the Batcave while learning that Batman is Bruce Wayne. When tipped off by Alice, Sophie later found that Renee had found Joker's joy buzzer first as Renee makes off with Poison Ivy's body. After getting Poison Ivy's body to a national park where she is still weakened, Renee tries to get through to Poison Ivy to no avail even when Poison Mary shows up.

Cartagena reprises her role from the first season of Gotham.

Jada has been working on ways to cure her son of this sociopathic personality. At the time when Marquis sent Victor Zsasz to take out Jada, she figures out that Ryan is Batwoman when she uses some fighting skills to defeat him.

Ever since then, Marquis has exhibited anger issues and sociopathic behavior such as using a magnifying glass to burn ants to deliberately triggering his father's peanut allergy for a laugh. While not wanting Ryan to associate herself with Marquis, Jada commissioned the recreation of the freeze serum with help from Virgil Getty in an attempt to put him on ice until a treatment could be found. After murdering Professor Pyg, Marquis reveals his true insane nature, and seizes control of Wayne Enterprises.

When Marquis had captured Jada and four other members of the Black Glove, he declared both of them fated due to the mutual effect of Joker's bus hijacking that ran Gabi's car off the bridge. After killing three of the Black Glove members, Marquis is attacked by Batwoman before he can finish off Jada. Mary later found out from Alice that she told Marquis about the Batcave.

When she found Beth and Ocean interacting while planning to make further use of the Desert Rose, Tatiana informed Safiyah who had their memories of each other suppressed by Enigma. After Alice caused a bat swarm so that Mary can make use of the Desert Rose, Tatiana was dispatched to Gotham City. She catches up with Alice at the time when Sophie Moore was planning to arrest her and knocks them both out. While Safiyah talks with Alice, Tatiana kept an eye on Whisper. After Safiyah was done with Alice, Tatiana returned them to Gotham City. Safiyah dispatched Tatiana to Gotham City again to make sure that Alice killed Ocean. She was fooled and had to fill in some blanks about Beth's history with Ocean. After Alice's fight with Ryan, Tatiana took her to meet with Safiyah. Thanks to Ryan, Safiyah found out that the body was a fake and had the real Ocean found. Alice was instructed to use the same knife on Ocean as Tatiana watched. Shortly thereafter Tatiana informed Ryan of the truth, that Safiyah didn't have Kate.

Due to her brother-figure Ocean wanting to make more use of the Desert Rose and Beth falling for him, Safiyah punished them by having her hypnotist Enigma suppress their memories of each other. Suspecting that Safiyah caused the airplane crash that supposedly killed Kate, Alice manipulates events that involve poison-carrying bats and the serum derived from the Desert Rose to attracted Safiyah's attention. This caused Safiyah to send Tatiana to pick her up. During a meeting with Alice, Safiyah denied any knowledge of causing the airplane crash and has Kate's necklace as proof that she is still alive. Though she wants Alice to do some unspecified job upon her return to Gotham City. This turns out to be looking for a man named Ocean. When Alice had what appeared to be Ocean's body delivered to Coryana, Ryan exposed the fake causing Safiyah to have her men look for Ocean. When Ocean was found, Safiyah had Alice use the same knife on Ocean which she reluctantly did. After Alice is removed from her home upon revealing that she doesn't have Kate, Safiyah removed the knife from Ocean where it turned out that the knife was coated in the Desert Rose. Safiyah also found out that Tatiana was the one who left the note from Safiyah toward Alice and uses the same knife on her vowing to Ocean that she'll remove it from Titania when she forgives her. In retaliation for the trickery, Alice sets fire to the Desert Rose crops which infuriates Safiyah. She later sends Ocean to find a Desert Rose that might be in Batwoman's possession. Safiyah removed the knife from Tatiana as they go to Gotham City to meet with Black Mask. During the discussion, Safiyah revealed that she was the one who leaked to him Kate Kane's flight plan despite not meeting Kate, how Enigma brainwashed Kate into being Circe Sionis, and also told him that Alice is Beth Kane. Both of them sent Tatiana and some False Face Society members to abduct Alice and Jacob Kane. With Alice in her clutches, Safiyah ranted to her about 7 villagers dying in the fire she started as Alice countered about Safiyah lying to her about having Kate. To free Alice, Batwoman gave up the Desert Rose in her possession to Safiyah. After "Circe" stabbed Black Mask in the hand while stating that she has Kate's memories, Safiyah advises Black Mask to tell "Circe" or she'll do it for him. Following Ocean's death, Safiyah meets Alice at the shore where she is spreading Ocean's ashes. While mentioning to Alice that Black Mask is having Circe procure a sample of Poison Ivy's plant from the Batcave to restore the Desert Rose crops, Safiyah states that she can offer sanctuary to Alice on Coryana. Alice then stabs Safiyah with the same knife that was used on Ocean vowing to remove from Safiyah when she has regained the things that she lost. Alice reveals that, after stabbing Safiyah, she took her body to a junkyard, tossed it in a random junked car, and then had the entire thing crushed, just to make sure Safiyah couldn't be revived.

Following the arrest of Candice Long, Ryan called Angelique to notify her and call a truce. After Angelique finds out that Sophie Moore had manipulated Ryan into bugging her phone, their relationship is strained again. As Batwoman, Ryan gets the information from Angelique on where Ocean can be found. Angelique wore a baby doll mask when two False Face Society members killed Commissioner Forbes. Ryan found out through Jordan Moore's description and had to persuade Angelique to leave that life. Though Black Mask would not take this departure lightly and had her tied up on a sawmill.

Safiyah found out through Tatiana and had them punished by having Enigma suppress their memories of each other. When Alice and Ocean reunite, suppressed memories start to surface of their time on Coryana. After fighting off the assassins sent by Safiyah, Alice and Ocean drive off. When Alice brings forward a white tube that was in the back seat, Ocean asks her if she has ever heard of Jack Napier. While in an abandoned subway tunnel, Ocean and Alice have more suppressed memories and end up surrendering the map to Sophie once Ocean burned off the blood. Alice then kills an Ocean look-alike to make it look like that Alice did her job as the two of them wait for Tatiana to show up. Tatiana was fooled by the look-alike and Ocean left Gotham City. After Ryan exposed the trickery, Safiyah's men found the real Ocean in Italy and had him brought to Coryana, Alice reluctantly used the same knife on him. Once Alice was removed from Safiyah's home after revealing that she doesn't have Kate, Safiyah removed the knife from Ocean where it turned out that it was coated in the Desert Rose. After using the same knife on Tatiana for tricking Alice with the note that pinned the blame of Kate's death on her, Safiyah told Ocean that she will remove the knife from Tatiana when she forgives her. It was also revealed that Ocean helped to make the Snakebite drug for the False Face Society with Angelique's help. Ocean was later dispatched to Gotham City to find the Desert Rose that might be in Batwoman's custody. His detour brings him to Enigma's office where Alice is. Enigma evades them by quoting "Mockingbird Anew" which restores their memories. Due to the Snakebite recipe being incomplete, Angelique states to Black Mask that she can help him find Ocean.

As Ocean and Angelique slowly work on the Snakebite drug, Batwoman works with Alice to rescue them with Ocean getting non-fatally shot in the process. After recovering, Ocean was present when Alice talked to Enigma about undoing the brainwashing she did to Kate. When Enigma stated that it required a password to fully undo the brainwashing alongside an item that belonged to Kate, Ocean snapped Enigma's neck much to the dismay of Alice as he stated that Kate will only put her back in Arkham Asylum if it worked. He later disposes of Enigma's body. After helping to procure items for Alice and Jacob Kane to restore Kate's memories, Alice later found Ocean dead in her hideout after slaying Tatiana.

According to him, Roman had a daughter named Circe who was captured by the Crows and was said to have been killed by Batwoman the day when Alice caused a mass-breakout at Arkham Asylum where Circe was incarcerated. While arranging for Kate Kane's capture and faking her death, Black Mask arranged for the False Face Society to distribute the Snakebite drug. After Black Mask had Forbes killed for speaking out about the Snakebite distribution, Roman gave his sympathies for the death on TV. Finding out that his operative Angelique was planning to leave the group, Black Mask had her abducted, tied to a chair, and facing the body of one of the plague doctor mask-wearing operative who failed him.

The next day, Black Mask had Enigma work on Kate. After sending one of his men to chloroform and drug Jacob with the Snakebite drug, Black Mask kills the members who murdered Forbes to tie up loose ends. One member states that the Snakebite drug production is stalled due to Angelique's arrest and Ocean going missing. As Roman, Black Mask visits Jacob leaving him the Snakebite drug claiming that someone placed it in Janus Cosmetics. Upon somehow hearing of Angelique's release, Black Mask sent some of his men to intercept the witness protection transport and reclaim Angelique. Afterwards, he plans to have Snakebite recreated with her help and starts enlisting drivers to help obtain the ingredients. When it came to the Fear Toxin, Black Mask ambushed Sophie Moore only for Batwoman to intervene and throw a Batarang into him. Both of them had to let Black Mask go due to him showing theatrical live footage of Angelique at the gunpoint of one of the False Face Society members. Upon hearing from Angelique that the Snakebite recipe is incomplete, Black Mask is told by her that she can help him find Ocean. Once that was done, Black Mask was present when Enigma finishes brainwashing Kate to be Circe Sionis. When "Circe" brings Alice to him after she helped Batwoman disrupt the Snakebite drug making and freeing Angelique and Ocean, Black Mask states that he knows about Alice and her now-defunct Wonderland Gang. While deciding not to kill Alice, Black Mask orders "Circe" to take Alice downstairs. After "Circe" tortured Alice, Black Mask was called down when Alice stated that she can tell him who the new Batwoman is. Once Black Mask was present, Alice noted that she knew Circe before her untimely death, her knowledge of Black Mask being Roman Sionis, and that she can make a new face for "Circe". Black Mask complied to allowing a new face to be made for "Circe" and even had to obtain a cosmetic to help out. After the work is done, Black Mask has Alice removed from the property while being advised to remain quiet on what transpired. Black Mask later met with where Safiyah revealed that she was the one who leaked to him Kate Kane's flight plan despite not meeting Kate, how Enigma brainwashed Kate into being Circe Sionis, and also told him that Alice is Beth Kane. Both of them sent Tatiana and some False Face Society members to abduct Alice and Jacob Kane. With Jacob in Roman's clutches, Jacob noted that he figured out that he was Black Mask. Due to three of the False Face Society members being the police officers that are secretly on Black Mask's side, Roman advises Jacob to be quiet about this information or else he will have his remaining family members exterminated. "Circe" returns to Black Mask where she mentions having Kate Kane's memories. After "Circe" stabbed Black Mask in the hand and demanding answers on those facts, Safiyah advises Black Mask to tell "Circe" or she'll do it for him. After "Circe" gets Kate's journal, Black Mask arranges for the police officers on his side to set up Ryan for possession of Snakebite and Roman briefly confronts her in a police car. While planning to have Ryan eliminated, Black Mask meets with former Crows operatives and persuades them to side with him. When Russell Tavaroff states to Black Mask that he would just be a "cog" in someone's device, Black Mask plans to make him a "machine" instead. Following the successful mission of "Circe", Black Mask starts to make use of the villain items that she stole from the Batcave. Instigating a riot on TV, Black Mask experimented on Russell Tavaroff using Bane's Venom and the Snakebite drug which didn't work at first. Alice later fought Black Mask while Ryan went after "Circe". When Black Mask states that he'll be a great villain, Alice comments that Joker was far worse, uses Joker's acid flower spray on Roman's face, and slams his mask on his face which permanently welds. Vesper Fairchild later reported that Black Mask and Alice were remanded to Arkham Asylum. Ryan briefly saw him stating the words "Janus" over and over.

Enigma finishes up on Kate and hypnotizes her into being Circe Sionis. Alice later visited Enigma again and suspended her from the ceiling when she asks her how to undo the brainwashing she did to Kate. Enigma states that she will need a personal item of Kate. After getting the keys to Kate's motorcycle, Enigma states that a password needs to fully undo the brainwashing as the motorcycle keys would be needed to trigger a memory. When Alice starts to ask for the password, Enigma's neck is snapped by Ocean much to the dismay of Alice as Ocean stated that Kate would put her back in Arkham Asylum. Ocean later disposes of Enigma's body and suggests to Alice that Enigma was the daughter of the Riddler; due to her having a cane that is similar to his.
