Dr. Robert Kirk Langstrom, a scientist is chiropterologist who was working on a cure for deafness and other diseases through bat DNA based on the T-99 mutagen he developed with Dr. Emile Dorian. After imbibing the serum, Langstorm suffered a horrible side effect that transforms him into a hideous man-sized bat-human hybrid. The serum also takes away his intelligence, reducing Langstorm to a crazed animal that mad rampage until Batman subdued the creature and injected Man-Bat with a counter-serum. As long as Langstrom refrained from imbibing the formula again, despite having developed a nightly addiction, he would remain in his human form.

Death Battle Info[]

As Man-Bat, whose genetic makeup uses DNA of various bat species that include vampire bat, Langstrom has vastly increased strength and the ability to fly and use echo-location. In a fight, Man-Bat uses his razor-sharp claws and fangs. While Langstorm manages to maintain control over himself, he would gradually submit to his animal instincts and be driven to harm friend and foe alike.

  • Has beaten multiple other villains of Batman, including Killer Croc, Deadshot and Rick Flag
  • Can easily throw vans around
