Cheetara left the doomed planet of Thundera with her fellow ThunderCats. Leaving behind the planet, Cheetara was instructed by Jaga to wake Lion-O from sleep, which she did, despite the objections of Snarf. When the Mutants boarded their ship, Cheetara joined the other ThunderCats and bravely fought them off. She was given a new outfit and her Staff to help defend herself on their new home by Jaga, along with her fellow ThunderCats. Cheetara helped defend the ship from the attacking Mutants, going into suspension to make the journey to the new planet chosen as the ThunderCats' new home. She was then revived with the others when they reached their new home on Third Earth, and after defeating the Mutants, prepared with the others to build a new home.
