Music like Runaway Planet

Thundarr the Barbarian is an American Saturday morning animated series, created by Steve Gerber and produced by Ruby-Spears Productions. The series ran for two seasons on ABC from October 4, 1980 to October 31, 1981, and was rerun on NBC in 1983.

Thundarr the Barbarian is set in a future (c. 3994) post-apocalyptic wasteland divided into kingdoms or territories — the majority of which are ruled by wizards – and whose ruins typically feature recognizable geographical features from the United States, such as New York City, Los Angeles, Las Vegas, Seattle, the Badlands, Mount Rushmore, Denver, Atlanta, Boston, San Antonio and its Alamo, San Francisco, Washington, D.C., Cape Canaveral, and the Grand Canyon. Other episodes with recognizable settings are set outside the United States, include Mexico and London, U.K.. Another notable feature of this future Earth is that the Moon was broken in two pieces. The shattered moon and the ruins of the former human civilization were caused by the passage of a runaway planet between the Earth and the Moon in 1994, which, from scenes shown in the opening sequence, caused radical changes in the Earth's climate and geography. However, by the time period in which the series is set, the Earth and Moon seem to have settled into a new physical balance. Earth is reborn as "New Earth", a world of "savagery, super-science, and sorcery" far more chaotic than "Old Earth" (the show's name for the preapocalyptic world).
