Thundera is a world in crisis in a distant galaxy. The plant has become unstable and will collapse soon. The people of Thundera, known as Thundercats, flee the dying planet in their spaceship. During the flight their ship is damaged when they are attacked by evil mutants. The eldest aboard, Jaga, sacrifieces himself to ensure that the ship lands safely to it's destination: Third Earth.

The remaining Thundercats (Panthro, Cheetara, Tygra, WilyKat, WilyKit, Snarf and Lion-O with the use the magic of the Sword of Omens) form a headquarters at a place they name Cat's Lair. From there, they fight the evil mutants with the goal of saving themselves and restoring peace to Third Earth. Meanwhile, the mutants have found a powerful new leader, Mumm-Ra, the Ever-Living. This will not be an easy fight.
