Bat (also once called "Mr. Bat" by Bird Brain) is a henchman of Bird Brain. Bat's first appearance was in Thunder Dog where he helped his boss steal equipment to build condos. He is a gray, furry creature with long, bunny-like ears. He wears a tuxedo and black glasses. He also has a pig-like nose. Bat is blind because of the common saying "You're as blind as a bat". Due to this fact, Bat constantly asks "Where?" in response to orders. This answer annoys Bird Brain.
Bat has a very deep voice. Bird Brain appears to like Bat more than Owl because, in one scene, Bird Brain was amazed that Bat did not ask his signature "Where?" to which Owl responded "Who?" Bird Brain then threatened to hit Owl with a boulder.
