Evolution of Man-Bat in games

In the original version of the story, Dr. Robert Kirkland "Kirk" Langstrom was a zoologist who tried to give humans a bat's acute sonar sense. He managed to develop an extract that could supposedly do this, but upon testing it on himself, he transformed into an anthropomorphic feral half-bat hybrid, lacking sentience and acting purely on instinct. Batman managed to reverse the effects, but Langstrom would return as the Man-Bat time and time again, albeit not necessarily as a villain, as Langstrom would sometimes retain enough sanity to use his powers for good. Several other characters have since appeared as similar Man-Bat creatures, including Langstrom's wife Francine and father Abraham.
