HISTORY
Dr. Kirk Langstrom was the resident authority on nocturnal mammals at the Gotham Museum of Natural History. Inspired by his admiration of The Batman (see Batman II), Langstrom hoped to give himself a natural sonar power like a bat's by taking increasing doses of a compound he extracted from a certain gland in bats [Anal.]. Langstrom succeeded, but to his horror, the compound also turned him into a grotesque bat-like creature. In this form Langstrom fought The Batman and turned increasingly insane. Finally, Langstrom forced his fiancée, Francine Lee, to let him turn her into a bat-like creature so they could mate. The Batman succeeded in injecting both Langstrom and Lee with an antidote [Batman Semen!], restoring them to human form and sanity.

Later, after being bitten by a vampire bat, Francine would uncontrollably become a vampiric bat-like creature under a full moon. Eventually, however, Francine was apparently permanently cured, and she no longer changes into bat-like form.

Able to change back and forth between his human and bat forms, using serums, Lamgstrom [Not my typo!] became a crimefighter as Man-Bat, emulating his hero, The Batman. Langstrom and Francine were married and had a daughter, Rebecca.

Rebecca became deathly ill, and what Langstrom thought was the only serum that could cure her was spilled in a fight between The Batman and a criminal. The Batman knew that the serum had been contaminated earlier, and Rebeccca was later curd by other means [With the help of Superman in DC Comics Presents!]. However, unjustly believing The Batman had nearly caused Rebecca's death, Langstrom sank into a severe depression. Accidentally taking an overdose of his bat-gland formula, Langstrom went insane upon next becoming Man-Bat. The Batman restore Langstrom to normal, but by forgetting to take the antidote regularly, Langstrom reverted to being the insane Man-Bat again. Once more The Batman restored him to human form [This entry is just a bunch of sentences comprised of "turned into Man-Bat" and "turned back into Langstrom." It's super exciting!].

Today Langstrom again appears to be in control of his transformations and remains sane when in his Man-Bat form.

POWERS & WEAPONS
By taking his bat-gland formula, Kirk Langstrom can transform himself into a bat-like creature. He can return to human form by taking an antidote.

As Man-Bat, Langstrom possesses superhuman strength, super-sensitive hearing, and the ability to fly at great speeds.

Like a bat, Man-Bat has natural sonar. He emits high-pitched sound waves and can hear the echoes they make when they bounce off nearby objects. Thus Man-Bat can navigate perfectly even in pitch blackness.
