Man-Bat

Man-Bat is a member of The Rogues and one of Batman's archenemies.

History
Well-meaning zoologist Dr. Kirk Langstrom was trying to cure deafness when he gave himself an injection of bat DNA. Instead, the experimental serum transformed him into a creature that was half-bat and half-minifigure, giving him wings and extra strength, but the mind and instincts of a wild animal. When on the loose, he can still be a real pest to Batman and the citizens of Gotham City.
