Dr. Kirk Langstrom, a scientist specializing in the study of bats, develops an extract intended to give humans a 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 into a hideous man-sized bat. The serum also takes away his intelligence, so he goes on a mad rampage until Batman can find a way to reverse the effects. The Man Bat is an instinctive villan only killing to survive.
