Bingo is a villain in Back at the Barnyard.

He is a chimpanzee test pilot who appeared only in the episode "The Right Cow". He crashed into the barnyard with his spaceship, and was found by the barn animals. At first, he seems friendly and courteous, and teaches Otis about being an astronaut, though this was a plan to get rid of Otis so he could be Barnyard leader.

He briefly took over the barn after sending Otis and Pip into space, but they were able to return and defeat Bingo. At the end, Bingo was blasted to outer space on a spaceship, vowing to return. At that time, fans speculated that he was going to be one of the main antagonists of the show, though he has never returned.
