The Show

It’s the planet Thundera, and the inhabitants are called the Thunderans. A feline humanoid species whose world is about to be destroyed. Also hailed by the Thundercats, they board evacuation spaceships to escape the planetary meltdown but only one ship survives. Responsible for the destruction is a group of mutants, led by Mumm-Ra.


The ship escapes to the nearest inhabitable planet, with the mutants in hot pursuit. On the new planet, they consolidate their position with the mutants posing a constant threat. Mumm-Ra is an ancient spiritual being filled with all the evil from centuries past. Luckily Lion_O has the use of the “Sword of Omens”, and takes the lead in the fight against Mumm-Ra.


At the beginning of each episode they show Lion-O swinging the “Sword of Omens” and voicing the phrase “Thunder…..Thunder…….Thundercats oh!”, followed by a showing of all the prominent characters like Cheetara, Panthro, and Snarf. The scene with the sword is reminiscent of He-Man and She-Ra, and one cannot help to think it was copied.



Thundercats became one of the most successful and popular animations of the 1980s, spawning various products like a very successful toy line, comics, and video games. Various reboots were attempted with a full-length feature film in the pipeline since 2007. Hold your thumbs.
