One of my favorite characters from my childhood was the “Great Gazoo”. I learned that right after they featured Gazoo, The Flintstones was cancelled. Clearly never resolving desire to return home to his planet from which he was banished. Here is some Gazoo bio.
The Great Gazoo is a character from The Flintstones animated series. He first appeared on the show on October 29th, 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 Zetox as punishment for having invented 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. Because Gazoo was introduced into the show midway through the final season and is considered quite an absurd character, being a futuristic alien that appears in the middle of the Stone Age, he is often cited by fans and critics of the show as being an example of the fact that the show had "jumped the shark." Indeed, the show was cancelled shortly after his first appearance, although it cannot be said that Gazoo contributed in any way to the series' conclusion.

Well....this is really off beat and I am curious if you have a character that you enjoy too?
Peace out there to you Dum Dum's,
Love in Christ too!
