Space Ghost is a super-hero character that was created by Alex Toth in the 1960s for Hanna-Barbera, the famous cartoon company. While the character was originally conceived as a standard superhero, he is more famous today for his return in the 1990s as a comedy character, particularly on the show 'Space Ghost: Coast to Coast', which was a parody talk show that included appearances from other Space Ghost characters such as Brak and Zorak.
