Ubergonzo is a relative of The Great Gonzo and the leader of the unnamed alien race to which they belong. He invites Gonzo to return to his homeworld in the movie Muppets from Space. After Gonzo decides that he prefers to stay on Earth, Ubergonzo invites the government agent Edgar Singer instead. Singer's comical attempt to destroy them caused the comedy-loving aliens to make him their ambassador to Earth. After this, Singer accepts the invitation and joins the aliens back to their home planet.
