PlotFrom the cover of the UK VHS
"From beyond any known galaxy, bringing with them the laws and ideas of their doomed planet, come the ThunderCats. These brave and courageous cat-like humanoids carry with them the powerful Sword of Omens, which contains the mysterious Eye of Thundera- the source of the power of all ThunderCats. But there's also a treacherous band of hideous mutants from the planet Plun-Darr who want the sword. Crash landing on Earth, the ThunderCats battle these evil creatures who are aided by the supernatural powers of the deadly and mysterious Mumm-Ra. You'll experience many incredible adventures in this epic science fiction saga."
A number of scenes in the movie are longer than they are in the single episode version. Some examples:
- A scene from the beginning of the movie; Jaga tells Cheetara to wake Lion-O, Tygra says that "Jaga's right". Wilykat's remark is cut from the episode version. He says "Jaga's always right" Then Panthro informs us "..not always, if he was he'd left a smartmouthing little squirt like you behind, Wilykat.."
- There is a scene where Wilykat locks his sister Wilykit in one of the suspension capsules, so during Jaga's farewell, she is locked up. This scene was cut from the single episode version.

The VHS release also features an extra; a short introduction of the main characters and the plot. It features alot of unique animation, some stock animation and some scenes from the first episode.
