Evil undead sorcerer of Third Earth
who worships Spirits of Evil
. Arch-enemy of Lion-O
and the Thundercats
. Although he is usually a shriveled corpse within his stone sarcophagus
, he invokes the Spirits of Evil
to infuse himself with immense power, becoming Mumm-Ra the Ever-Living. In this form, he is nearly undefeatable, but for one minor weakness - he cannot abide the sight of his own face.
Mumm-Ra is dedicated to eradicating the Thundercats, and will do everything in his power to achieve that goal. He often works with Slythe and his band of evil mutants.
