Man-Bat

The Man-Bat is sighted in Alexander Luthor, Jr.'s Secret Society of Super Villains during the events of the 2005–2006 storyline Infinite Crisis.[8]

In the aftermath of that storyline, both Kirk and Francine are shown to be alive in the 2006 "One Year Later" storyline. Talia al Ghul binds and gags Francine, and then threatens to poison her if Kirk does not give her the Man-Bat formula. After Langstrom gives her the formula, she releases Francine as promised. Talia utilizes the Man-Bat to turn some generic members of the League of Assassins into Man-Bat Commandos.[9]

In Gotham Underground, the Man-Bat is apprehended by the Suicide Squad.[10] He is one of the villains seen in Salvation Run.[11] Francine has appeared in Batman and the Outsiders, serving as the team's technical advisor, and her assistant Salah Miandad operates the "blank" OMAC drone known as ReMAC. In issue #10 of that series, Kirk appeared, seemingly healthy and also aiding Francine.

In the 2008 miniseries Final Crisis, the Man-Bat has been turned into a Justifier and was shown attacking Switzerland's Checkmate Headquarters.[12]

During the 2009 "Battle for the Cowl" storyline, following Batman's apparent death, Kirk is haunted by nightmares of becoming the Man-Bat and killing his wife. When Francine disappears, he takes the serum and tries to follow her. After an altercation with the Outsiders, he returns to his human form and is captured by Doctor Phosphorus, who reveals that the serum is not necessary to trigger the change. Kirk discovers that Phosphorus has also captured Francine and becomes the Man-Bat to save her.[13]

During the 2009–2010 Blackest Night storyline, Francine tracks down Kirk (as the Man-Bat), having created a cure, and revealed that Kirk's next transformation would be permanent if he did not drink it.[14] Kirk attempts to take the cure, but his Man-Bat persona will not let him. Just as Kirk is about to drink it, Francine is wounded in the crossfire of the battle between Black Lantern Solomon Grundy and Bizarro (the latter of whom is already at the scene, trying to prevent Kirk from taking the cure). Distraught at Francine's injuries, Kirk transforms into the Man-Bat, seemingly permanently.[15]

In Batgirl (vol. 3) #10-11, the Man-Bat is seen under the control of the Calculator as a techno-zombie.[16]

In the "Collision" storyline of Red Robin, following Red Robin's actions against Ra's al Ghul and the League of Assassins, the latter attempts to murder people related to the Bat-Family. The Man-Bat, following Red Robin's orders, protects Julie Madison, a former lover of Bruce Wayne, against Ra's al Ghul's assassins.[17]

In The New 52 (a 2011 reboot of the DC Comics universe), the majority of Kirk Langstrom's history is rebooted. The Man-Bat serum first appears in Detective Comics #18 (May 2013). Ignatius Ogilvy also comes into possession of the Man-Bat serum, which he uses as an airborne virus to spread throughout Gotham City's "900 Block".[18]

In Detective Comics (vol. 2) #19 (June 2013), Kirk Langstrom first appears where he and his wife Francine are escorted by Batwoman to Batman's location. Langstrom reveals that he is the creator of the serum, intending to help deaf people. Taking responsibility as the creator of the serum, he uses a sample of the serum Batman had obtained to inject himself. This creates an anti-virus which also spreads through the air. Langstrom is turned into a Man-Bat (the last remaining Man-Bat) as his anti-virus cures the remaining citizens of Gotham.[19]

Langstrom re-appears in Batman Inc. (vol. 2) #10 (June 2013) apparently giving Batman the serum. He claims to be working on an aerosol antidote to the serum as well.[20]

The backup feature of Detective Comics (vol. 2) #21 (August 2013), focuses on Langstrom and his wife. He changes from the Man-Bat form into his human form and becomes addicted to the Man-Bat serum, taking it every night. He apparently does not remember his actions from the previous night, yet worries that a string of reported killings are his fault.[21]

During the Forever Evil storyline, the Man-Bat is among the villains that were recruited by the Crime Syndicate of America to join the Secret Society of Super-Villains.[22] The Scarecrow and the Man-Bat attempt to steal the frozen Talons (assassins that are associated with the Court of Owls) from Blackgate while the Penguin is having a meeting with Bane. Bane arrives at Blackgate as the Man-Bat and his fellow Man-Bats are attempting to transport the Talons to Mr. Freeze and is able to keep one from leaving.[23]

The final issues of the Batman: The Dark Knight series would establish that Kirk is the son of a corrupt wealthy pharmaceutical businessman named Abraham Langstrom, who considers his son as a failure when compared to Bruce Wayne, the son of his business rival Thomas Wayne. Abraham would steal his son's serum, make some of his own improvements and use it to target the homeless (because no one would miss them) before being stopped by Batman, though he is able to plead temporary insanity to avoid going to prison.[24]

In the Watchmen sequel Doomsday Clock, the Man-Bat is featured on the news as an example of the "Superman Theory" where the government has been experimenting on humans to give them superpowers.[25] The Man-Bat later accompanied Black Adam in his attack on the White House.[26]

In Harley Quinn Rebirth, Langstrom's wife goes on a rampage against Harley and her friends, turning Harley and her friend Tony into Man-Bats as part of the Penguin's plan to break Harley's spirit. Their other friends get Langstrom released and he helps them find the antidote before predictably escaping himself.

As mentioned above, Talia al Ghul captured Kirk Langstrom and threatened to poison Francine if he did not give her the Man-Bat formula. Kirk gives in to Talia al Ghul's commands where she uses the Man-Bat formula on some generic members of the League of Assassins to turn them into the group's Man-Bat Commandos.[9]

In The New 52 (a reboot of the DC Comics universe), various Man-Bats have appeared under the control of Talia al Ghul in her plot to destroy Batman.[27] It is later explained that Talia al Ghul had an agent steal the serum from Langstrom's laboratory to use on her soldiers to create the Man-Bat Commandos.[19]

During the "Forever Evil" storyline, some Man-Bat Commandos were used to help the Crime Syndicate hunt down the Rogues. The Mirror Master managed to trap some of them in the Mirror World. When a Man-Bat snatches up the Weather Wizard, the other Rogues members chase after it until it crashes into a solid wall of ice upon arriving in Mr. Freeze's territory.[28]

Back when Thomas and Martha were still alive, Kirk Langstrom had a father named Abraham whose company Patriarch Biopharmaceuticals competed with Wayne Enterprise. Years after the death of Thomas and Martha, Abraham continued his shady deals which involved exploiting his son's Man-Bat serum which he plans to make a profit on it. He soon became addicted to the upgraded serum. When he became Man-Bat, Abraham targeted the homeless people of Gotham City and draining them of his blood. This caused Batman to team up with Kirk Langstrom to fight Abraham.[29] Because the skin of Abraham's Man-Bat form was tough, Batman injected himself with the cure and tricked Abraham into drinking his blood enough to regress back to normal. Batman then handed Abraham over to the police. After evading incarceration by claiming that he had no knowledge on what his Man-Bat form did, Abraham returned to his company. Though he is weary over the fact that Batman will catch him when he makes a mistake.[30]

In Countdown to Final Crisis: The Search For Ray Palmer, an alternate version of the Man-Bat was shown. He is from Gotham by Gaslight (Earth-19), and has experimented with bats similar to his mainstream counterpart. He is later defeated by the Blue Beetle and Batman.

In the alternate timeline of the Flashpoint event, the Man-Bat is killed by Miranda Shrieve, the granddaughter of Matthew Shrieve.[31] In a flashback, the Man-Bat was invited by Lt. Matthew Shrieve to be a new member of the Creature Commandos, but the Man-Bat then betrays him, killing his family.[32] It is revealed that the Man-Bat had been working with General Sam Lane, who is responsible for the deaths of Miranda's family.[33]

In the Elseworlds story JLA: The Nail, a captured Man-Bat makes an appearance in Professor Hamilton's Cadmus Labs.[34]

In the Batman Beyond comic series set decades after Batman: The Animated Series, it is revealed that shortly after Batman cured Francine of the Man-Bat serum, she and Kirk started to live a peaceful life as they started studying sonics and had two children. However, Francine developed an aggressive form of Parkinson's and had a short life expectancy, leading Kirk to try and perfect the Man-Bat serum to save her life, but by the time he did it, it was too late. Following this, his children left him, angered that he did not spend as much time with her during her final days. Devastated by "losing" his family, Kirk turned to the serum, which has been perfected to the point where he is able to talk and control his actions, and had been living in secret as the Man-Bat ever since. Three years prior, he rescues a girl named Tey, who was a hostage of the Jokerz, and injects her with the Man-Bat serum, leading the two to fall in love. In the present, Kirk, now as a white-bearded Man-Bat, tries building his own cult of Man-Bats, plans to use Kanium to help his cult control themselves better in their Man-Bat forms and sets up a destructive weapon that concerns the police. Bruce tries to reason with Kirk, but it only results in Kirk viewing both of them as monsters and setting up his bomb to destroy the two of them. However, Batman rescues Bruce in time. The Man-Bat tells Bruce to use his second chance wisely as he detonates the bomb to kill himself.

The Man-Bat appears in the Smallville comic Smallville Season Eleven. In Gotham City, the yellow rings of Parallax head to Arkham Asylum. There, Batman and Nightwing are doing their best to contain the newly powered inmates of Arkham, including the Man-Bat, who have already been transformed into Yellow Lanterns. Luckily, Superman arrives just in time to offer assistance to Batman and Nightwing. Superman is fighting with the Man-Bat and before taking him down, Superman says to the Man-Bat that, if there is more man than bat inside of him, then he takes no joy in this. Emil Hamilton succeeds into finding a way to reboot the rings, so when he does, all the Yellow Lanterns, including the Man-Bat, are released from the influence of fear and lose their powers, with the rings turning black. After their rings get rebooted and they lose their powers, the inmates of Arkham fall from the sky, unable to do anything to escape from their eventual death, but Superman manages to save them all. After Parallax's defeat, all the now-depowered criminals return to Arkham Asylum.

In the Injustice: Gods Among Us prequel comic, the Man-Bat appears in the villain's exclusive bar World's End, attempting to enjoy a drink when Wonder Woman and the Flash arrive in their search for Mirror Master. In Year Five, the Man-Bat meets with Black Mask, the Bronze Tiger, the Mad Hatter, the Scarecrow, and Tweedledum and Tweedledee until their meeting is crashed by Damian Wayne. When the villains start to overwhelm Damian, Deadman arrives where he possesses the Bronze Tiger and knocks out the villains before calling for help.

In the prequel comic to Injustice 2, the Man-Bat is shown to be a member of this universe's Suicide Squad. He is eventually murdered when Grodd usurps Solivar and Ra's al Ghul, who previously held custody of the Squad.[35]

The Man-Bat in The Batman

• Kirk Langstrom/Man-Bat appears in The Batman, voiced by Peter MacNicol while special sound effects provide the Man-Bat's vocal effects. This version is an employee at Wayne Enterprises doing research on bats and apparently afflicted with albinism. When Bruce Wayne begins to cut off the funding for his project, Langstrom tells Bruce that he needs the project to cure his niece's deafness. When Bruce discovers that Langstrom is lying, he goes to Langstrom's office to discover both Langstrom's obsession with Batman and the project's real purpose. Langstrom arrived in his vault to find his boss there; he admits that he created the formula so he could be feared like Batman, and drinks a serum, resulting in his Man-Bat transformation. He attacks Bruce at his office, and escapes. Batman confronts the Man-Bat in Gotham City's skies, landing on the ground, and Langstrom reverts to his human form. To be safe, Batman destroys one of Langstrom's vials. Langstrom drinks the remaining vial, transforms into the Man-Bat, and kidnaps Detective Ethan Bennett. Batman confronts the Man-Bat in a sewer, where Langstrom reverts to his human form, and is taken away to Arkham Asylum. While in Arkham Asylum, Langstrom is trying to recreate the Man-Bat serum, while the Penguin finds a sonar device to control a large condor, but ends up with a sonar device designed to control bats. When the Penguin uses the device, dormant remnants of the Man-Bat serum still inside Langstrom reawaken, resulting in his Man-Bat transformation and instinctively leading him to the Penguin's hideout. With the sonar device, the Man-Bat does the Penguin's bidding, returning him to his human form by saying "rest". Langstrom is furious with the Penguin when he learns the Penguin's plans, promising that the Penguin will feel the Man-Bat's wrath. At the docks, Batman confronts the Man-Bat and, using his own sonar device, induces a reversion back to his human form. Langstrom and Penguin are both taken back to Arkham. Langstrom later returns in as one of the many villains captured by the vigilante Rumor. He was shown in his human form and later in his Man-Bat form, implying that he has full control over his transformation. Langstrom made one last appearance, no longer a villain and renouncing the Man-Bat name. Batman charged Langstrom with creating an antidote for his own mutagen that some college students had stolen from him and were planning on infecting the entire student body with.

• Kirk Langstrom/Man-Bat appears in Beware the Batman, voiced by Robin Atkin Downes. In "Doppelgänger", Dr. Langstrom was working on a cure for diseases with bat DNA before Professor Pyg and Mister Toad raided his laboratory and forced him at gunpoint to mutate into a man/bat hybrid with a corrupted version of his formula. The two used a drug-filled mechanical collar to control the Man-Bat and force him to rob chemicals so that they can recreate Dr. Langstrom's formula and turn humans into human/beast hybrids. After the Man-Bat is captured and freed from control by Batman and Katana, he repays the two by helping defeat Professor Pyg and Mister Toad. After defeating the villains, the Man-Bat swears to work in the shadows on a cure for his condition. In "Alone", the Man-Bat is recruited by Katana alongside Metamorpho and the Oracle to help Batman in the final battle against Deathstroke the Terminator. They all go to the Batcave to take down Deathstroke's C4 bombs spread around.

  • Dr. Kirk Langstrom first appeared in Batman: The Animated Series. This version was a zoologist at the Gotham City Zoo. He first appears in the episode "On Leather Wings", where he steals serums from the chemical labs and is mistaken for Batman. The beast then commits other thefts at night and people start to question if it is Batman or some other masked hero. Batman recovers a strand of hair from the laboratory to which Bruce Wayne takes to Dr. March (Langstrom's father-in-law) to be analyzed and told that it is only from a little brown bat. But shortly after, Batman discovers that March is lying and travels to the laboratory. On the same night, Langstrom drinks the serum, when Batman arrives to question him—revealing Dr. March as the thief of the serum from the chemical labs. Langstrom tells Batman that he had discovered a chemical that created a new species that was neither man or bat, which he started taking, but could not control it. Langstrom reveals to Batman that the creature is in him and he transforms into a half-man/half-bat monster before attacking Batman. After a battle across the Gotham City skyline, the Man-Bat is knocked out and taken back to the Batcave. Batman manages to flush the formula out of Langstrom's system after discovering the chemicals that were stolen and he is returned to normal. Langstrom next appears in the episode "Tyger, Tyger", where he analyzes the chemical that Dr. Emile Dorian used for his experiments. In the episode "Terror in the Sky", Langstrom is having a dream that he transforms into the Man-Bat and begins to commit crimes. Then Langstrom is awakened, just to find the remains of a fruit and scratches from a rag. Batman and Langstrom eventually discover that the other Man-Bat turns out to be his wife Francine Langstrom, accidentally exposed to an alternate Man-Bat serum created by Francine's scientist father, who was trying to alter Langstrom's work. In the end, Batman cures Francine as well and she returns to her husband.
  • Kirk Langstrom appeared in The New Batman Adventures. He made a cameo appearance during Bruce Wayne's wedding in the episode "Chemistry".

When Batman sees the Man-Bat flying over Miagani Island, he intercepts it and takes a blood sample to determine the creature's identity. Batman uploads the sample analysis to Alfred, who identifies that the blood belonged to Dr. Kirk Langstrom. Batman goes to Langstrom's laboratory in Chinatown and sees video tapes showing the Man-Bat's origins. Similar to the comics, the Man-Bat was created by testing a formula based on vampire bat D.N.A. to cure his deafness while in the presence of Francine Langstrom. When Kirk transforms, he loses control of his Man-Bat form and accidentally kills Francine. Batman identifies the cause of death as blunt trauma to the head, deducing that Langstrom had no idea what he was doing. After several encounters, Batman creates an antidote and injects it into the Man-Bat to change him back to Kirk Langstrom, locking him in the Batmobile's trunk while the process completes. Once at the Gotham City Police Station, Batman then places Kirk in an isolation cell. Kirk is last seen crying in his cell over his role in Francine's death. If Batman walks inside Langstrom's laboratory after this side mission, he discovers Francine's body gone and a blooded painting on the broken window which says "Forever my love", implying that she became the She-Bat. If the date on the console or computer the game is on is changed to October 31 (Halloween) to any year, grappling around buildings will eventually make the Man-Bat jumpscare occur once again. Returning to the Gotham City Police Department and speaking to Officer Boulden will reveal that Kirk Langstrom apparently morphed back into the Man-Bat and broke out of his cage with Cash firing at him, but missing due to the speed at which he flew. Batman will state "I was afraid this would happen", prompting Boulden to reply with "Happy Halloween, huh?"
