Kirk Langstrom was a scientist who specializes in the study of bats and had at onetime becomes the creature known as Man-Bat.


At the beginning, he works for Ra's al Ghul in an attempt to create an army of Man-Bats to strengthen the League of Assassins. Kirk Langstrom was also behind the mutagen that Killer Croc empowered himself with where he had sprouted a tail. After Ra's al Ghul's death, Deathstroke recruits him to continue his work. This time, Deathstroke takes his wife Francine and daughter Rebecca as hostages and keeps them separated as motivation to force Langstrom to create the Man-Bat Formula. When Batman finds a lead in Kirk Langstrom's lab, he is attacked by a mutated ape that was living there. All three are later rescued by Batman and Damian Wayne. During his rescue, Damian tries to interrogate him but causes Deathstroke's men to be alerted and ensuring fight.

While the mutagen is complete by then, Langstrom is later taken to the Batcave by Nightwing to create enough antidote to stop the Man-Bats that Deathstroke created.

He was erased from existence when The Flash created a second Flashpoint.




  • When developing a cure for the Man-Bat victims, when Nightwing is communicating with Batman he calls him Bruce within ear shot of Kirk. This could mean that Langstrom already knows Batman's secret identity, or it was just an oversight on the filmmaker's part.
  • Kirk Langstrom is a vegan. (Likely as a result of his time as Man-Bat, which was created with vampire bat DNA).
