Man-Bat

Man-Bat (real name Dr. Robert Kirkland Langstrom aka Kirk Langstrom) is a fictional character in the DC Universe, 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 is 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.

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 in numerous version in the animated Batman cartoons, the associated toys, and in the video games. He was considered as an antagonist in one of the unproduced scripts for a fifth Joel Schumacher Batman film.

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.
