Synopsis
The Ancient Spirits of Evil give new life to Mumm-Ra and Ma-Mutt, send them to New Thundera, and build a new Pyramid for Mumm-Ra. The Thundercats say goodbye to Third Earth and depart for Thundera, leaving Tygra and Pumyra behind to watch Cat's Lair and the Tower of Omens. The Thundercats soon arrive and begin plans to build a new lair. Mumm-Ra meanwhile learns that the planet's gravity is controled by the Gyroscope under the Churning Rocks at the center of the planet. The Gyroscope is guarded by Jaguara, an ancient Thundercat sorceress. Mumm-Ra disguises himself as Jaga and puts Jaguara under a spell, making her change the rotation of the Gyroscope to throw the Thundercats clear off the planet. As the Thundercats are floating away, Lion-O calls on the Eye of Thundera to help him, and it breaks Mumm-Ra's spell... but not before Mumm-Ra takes part of the Gyroscope's regulator. Without those controls, the planet will be destroyed within 2 hours...
