Man-Bat (The Batman)

History
Dr. Kirk Langstrom was an employee of Wayne Enterprises, one day Bruce asked him what he was doing, and Langstrom told bruce that he was trying to cure his grand-daughter's deafness. He was really trying to turn himself into a "Batman", which Bruce soon found out after an embarrasing visit with Langstrom's Grand-daughter that included:Sign language, a lot of yelling and a hearing aide. Bruce went back to langstrom and langstrom turned into Man-bat, terrorising the city and desperatly trying to find blood.

In the episode Pets Penguin used a sonic device to take control of Man-bat's mind and he used man-bat as a tool to steal gold. Eventually Batman got his own sonic device and used it to make Man-bat attack penguin.

Man-bat was captured by Rumor.
