Mumm-Rana

Mumm-Rana is an ancient sorceress for good and counterpart to Mumm-Ra. She lives in the White Pyramid where her powers (apparently bestowed upon her by "the Ancient Spirits of Goodness," whom she invokes in her very first appearance) keep her from traveling too far. She at one time battled Queen Luna (grandmother to the Lunatak Luna) to stop her rampage across Third Earth. She did so by stripping Queen Luna of her magical belt which she later lost to Luna (it was destroyed eventually). Much like Mumm-Ra, her powers limit the time she can spend outside of her pyramid home. Mumm-Rana's level of power is somewhat unclear, as she was seen to be bested in battle by Mumm-Ra in the first appearance (he used a spell to trick Mumm-Rana into thinking that the Thundercats are evil), but she was also shown to be considerably more powerful than both Queen and Princess Luna, as she defeated both of them with relatively little effort.
