Thundarr The Barbarian was a half hour cartoon. In this cartoon, a comet went between the Earth and the Moon. This broke the Moon in half and plunged the planet Earth into chaos. A new society was formed 2000 years later, but it was like our past. It was a world of swords and sorcery, of good versus evil. Thundarr was a slave who got free and chose to fight the forces of evil who ruled the land. The series premiered on October 4, 1980 on ABC. It was a Ruby-Spears Enterprises Production.
