[1][2][3] The Great Gazoo is a tiny, green, floating scientist who was exiled to Earth from his home planet for inventing a Doomsday Device.

The creation of the Great Gazoo is attributed to writer Joanna Lee, who wrote more than 20 episodes of The Flintstones.

Other proposed names for Gazoo were Rip van Zonk, Hocus the Pocus, Dr. Puckwuck, and Shagelbextyzinkus (Ol' Shaggy for short).

[4] In her original character description, Lee described Gazoo as "a mirror, reflecting life's vicissitudes, vagaries, ritual magic and dreary reality.

[7] In the 2000 film The Flintstones in Viva Rock Vegas, Gazoo (portrayed by Alan Cumming) is exiled to Earth by Gazaam the Mighty for his crazy hare-brained schemes.

Gazoo makes a cameo in the Looney Tunes short titled "Attack of the Drones", where he attends Duck Dodgers' meeting with the other members in the space force about saving the Earth from obsessed eating alien monsters known as Eaters.

Gazoo appears in the 2016 DC Comics Hanna-Barbera Beyond series The Flintstones, where he is human-sized, does not float, and was sent by bookie aliens to evaluate the human race.

In this episode, he first appears disguised as a mysterious futuristic alien creature who zapped the dinosaurs with his bubble laser, only to transport them to his spaceship jail.
