The RatStar, manned by the Mutants, attacks the Feliner. S-S-Slithe, Monkian and Jackalman are ejected from the RatStar and fall toward the ground. They are saved from certain destruction by Mumm-Rana, a female mirror image of Mumm-Ra, a force for good who lives in a White Pyramid. Mumm-Rana is led to believe that the Mutants are good and the Thundercats evil. Mumm-Ra enthralls her and turns her power against the Thundercats. She puts the Sword of Omens in stasis and threatens the Lair itself. Lion-O disguises himself as a wealthy Tabbut and, with Tygra's help, sets himself up to be robbed by the Mutants. Mumm-Rana witnesses the attack, and the true and evil nature of the Mutants is revealed to her. The revelation breaks Mumm-Ra's spell and Mumm-Rana releases the Sword of Omens. Mumm-Rana and the Thundercats now defeat Mumm-Ra and the Mutants, but her ordeal threatens to destroy Mumm-Rana. In a desperate race for time, the Thundercats return her to the White Pyramid, where her powers are rejuvenated.
