Man-Bat

Man-Bat is Kirk Langstrom, (voiced by Marc Singer and Dee Bradley Baker) a scientist who developed a serum that transforms him into a bat-creature. This has made him a formidable adversary to Batman. Langstrom hates turning into a monster, and constantly works to cure himself. Bruce Wayne has become close friends with Langstrom and helps fund his research. His wife is scientist Francine Langstrom, who has also been She-Bat. He has also been a member of the Secret Society of Super-Villains.
