Introduced in Detective Comics #400 (June 1970) as an enemy of the superhero Batman,[1] the character belongs to the collective of adversaries that make up his rogues gallery.

He managed to develop an extract that could supposedly do this, but upon testing it on himself, he transformed into an anthropomorphic feral half-bat hybrid, lacking sapience and acting purely on instinct.

Since his debut at the end of the Silver Age of Comic Books, the Man-Bat has been featured in various media adaptations, including television series and video games.

[2] The character made his first appearance in Detective Comics #400 (June 1970) and was created by Frank Robbins and Neal Adams in collaboration with editor Julius Schwartz.

Dr. Kirk Langstrom, a zoologist who specializes in chiropterology, develops an extract intended to give humans a bat's acute sonar sense and tests the formula on himself.

On another occasion, in Action Comics #600, Jimmy Olsen inadvertently puts Superman into a cave occupied by the Man-Bat to protect him from kryptonite radiation.

Talia al Ghul binds and gags Francine, and then threatens to poison her if Kirk does not give her the Man-Bat formula.

[12] Francine appears 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.

[13] 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.

The Man-Bat, following Red Robin's orders, protects Julie Madison, a former lover of Bruce Wayne, against Ra's al Ghul's assassins.

[20] Emperor Penguin later made use of Langstrom's Man-Bat serum when he combined it with the Venom drug and one of Poison Ivy's plant concoctions to empower himself.

[23] During the "Forever Evil" storyline, the Man-Bat is among the villains recruited by the Crime Syndicate of America to join the Secret Society of Super-Villains.

[24] 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.

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.

With his sonar radar, Kirk can emit high-pitch sound waves and hear those echoes when they bounce off of nearby objects, thus enabling him to navigate perfectly in the darkness.

If in the Man-Bat form for long periods of time, he loses control over his bestial side that works purely on instinct, plus making him prone to harm friend or foe alike.

As mentioned above, Talia al Ghul captured Kirk Langstrom and threatened to poison Francine if he did not give her the Man-Bat formula.

story line, Talia al Ghul sends the Man-Bat Commandos to destroy Jezebel Jet's airplane.

[31] 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.

Years after the death of Thomas and Martha, Abraham continued his shady deals, which involved exploiting his son's Man-Bat serum which he planned to profit from.

After evading incarceration by claiming that he had no knowledge on what his Man-Bat form did, Abraham returned to his company, though he was wary of the fact that Batman may catch him if he ever makes a mistake.
