Dr. Kirk Langstrom was the resident authority on nocturnal mammals at the Gotham Museum of Natural History. Inspired by his admiration of the Batman, 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. Langstrom, succeeded, but to his horror, the compound also turned him into a grotesque bat-like creature. In this form Langstrom fought Batman and turned increasingly insane.
