The Great Gazoo is a character from The Flintstones animate series. He first appeared on the show on October 29, 1965. He has many similarities to Mr. Mxyzptlk of the Superman comics, and may have been inspired by him. He is a tiny, green, floating alien, voiced by Harvey Korman, having been exiled to Earth from his home planet Zatox as punishment for having invented a doomsday machine, a weapon of immense destructive power, and was discovered by Fred and Barney when his flying saucer crashed. His invention was a button which would destroy the universe if pressed, though he insists he made it on a whim with no intent of using it.
