ThunderCats (1985)

Episode Overview

Lion-O, Panthro, and Snarf embark on a quest to find additional pieces of the Treasure of Thundera, but Mumm-Ra has other plans in store. He ensnares them in the icy caverns on Thundera. Meanwhile, on Third Earth, the Luna-tacs are desperate for a new energy source for their ship. They capture the other Thundercats and force them to use exercise machines to generate power. The Thundercats cleverly overload the system, enabling their escape from the Sky Tomb. Back in the caverns, Snarf uses his tail to deliver the Sword of Omens to Lion-O, allowing them to break free and return to Third Earth.
