Man-Bat

Man-Bat (real name Dr. Robert Kirkland "Kirk" Langstrom) is an enemy to Batman, who first appeared in Detective Comics #400, illustrated by Neal Adams.

History
Dr. Kirk Langstrom, a scientist specializing in the study of bats, develops an extract intended to give humans the bat's sonar sense and tests the formula on himself because he was becoming deaf. While it works, it has a horrible side effect: it transforms him gradually into a hideous humanoid bat-like monster.

He first clashes with Batman when he tries to steal the chemicals needed to reverse his transformation, but his control over the new animalistic instincts resulting from his bat-like state is tenuous, and Batman is forced to subdue him in order to administer the antidote.

Langstrom later refines his serum, enabling him to retain his human intelligence while in bat form, and allowing himself control over his transformations. He works for a while as a detective and independent crime fighter as Man-Bat, while he and his fiancee, Francine marry and have a daughter, Rebecca. Eventually, however, his instability returns and he is left unable to control his transformations. In this condition, he clashes several times with Batman in the Batcave (which he finds by following other bats through the network of caverns; he does not recall its location in human form, and he never knows Batman's secret identity), believing — erroneously — that his daughter is dead and that Batman is somehow responsible.

Although he briefly regains control of his transformations, this appears to have changed. He begins to suspect that his cures missed an element of the serum, and he's losing control to his bat side. He believes he has slaughtered his own wife, son, and daughter.

However, both Kirk and Francine are shown to be alive in the "One Year Later" storyline. In Batman #655 (September 2006), Talia al Ghul ties up 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 mutagen to turn members of the League of Assassins into Man-Bats.

Man-Bat is also shown to be one of the captured villains in Salvation Run.

Powers

 * Transformation: Upon injection of his bat gland extract, Kirk Langstrom can transform himself into a half-human/half-bat creature. Once the serum wears off, the Man-Bat returns back to human form. Currently, Langstrom no longer needs the serum to transform.
 * Flight: Man-Bat can fly by way of artificially generated leather wings.
 * Claws: The Man-Bat has sharpened claws which are strong enough to easily tear through flesh and muscle.
 * Echolocation: Man-Bat can navigate through the air by way of echolocation, similar in function to a bat's radar.
 * Superhuman Strength
 * Superhuman Speed
 * Superhuman Senses: Vision, Hearing and Smell in superhuman levels.

Abilities

 * Genetics
 * Biologist

Elseworlds
The Batman: Man-Bat mini-series, by Jamie Delano and John Bolton, is an Elseworlds showing Kirk and Francine, now living exclusively in bat form, with a teenaged son, Eugene. Man-Bat, more unstable than ever (although at least coherent), is determined to replace the human race with a "superior" species of man-bat hybrids. There's nothing about this story that suggests it was originally intended to be an Elseworlds episode, which suggests that it was assigned that way because it effectively made Man-Bat into a Ra's al Ghul-style megalomaniac, which apparently contradicted other plans for the character. Some assume that the comic was already completed or close to completion when the conflict arose, leading DC to go ahead with its publication but under the Elseworlds banner.

In other media
Man-Bat has appeared numerous times in the animated Batman cartoons, the associated toys, and in the video games.

Batman: The Animated Series

 * See: Man-Bat (Batman: The Animated Series)


 * In the Justice League Unlimited episode "The Doomsday Sanction," Professor Milo mentions that Dr. Langstrom's research has proven useful to his experiments splicing together human and animal DNA for the Cadmus Project. This ended with a disaster when a mutated warthog was mentioned to have destroyed his lab.
 * In Batman Beyond, a new trend called "splicing" involved fusing together animal and human DNA. The new Batman Terry McGinnis, ends up captured by the leader of the splicers, Abel Cuvier aka Chimera, and is injected with vampire bat DNA and ends up resembling Man-Bat. He is later turned back to normal by Wayne.

Film
Man-Bat was considered as an antagonist in the third and fifth films of the Burton/Schumacher Batman series but ultimately wasn't used.

Video games

 * In the Super Nintendo game The Adventures of Batman & Robin, Man-Bat is one of the bosses. In this game he speaks, although in the show he never spoke in Man-Bat form.
 * Man-Bat is perhaps the only major Batman villain never to even be referenced in either Batman: Arkham Asylum and Batman: Arkham City, with the exception of a possible hint involving a chalice in Arkham City.
 * It is possible that Man-Bat is referenced in Batman: Arkham Origins as Alfred describes seeing a "king bat" nesting in the Batcave. Leading to some fans speculating that Man-Bat does in fact exist in the Arkham universe and is nesting in the Batcave.
