Mumm-Ra the Ever Living: The primary nemesis of the Thundercats, this slave to the Ancient Spirits of Evil has survived
for thousands of years on Third Earth. He possesses incredible magical powers, and is also the
wielder of the awesome Sword of Plundarr. His only weakness is a limited stamina; he needs often to
return to his Pyramid to regenerate.
Ma Mutt: Loyal "Dog" of Mumm-Ra
PummRa: Mumm-Ra disguised as a Thundercat. He used this disguise in
an early attempt to steal the Sword of Omens.
Driller: A mercenary Third Earthian who works for diamonds. He requires diamonds or other such hard
material to maintain his drill point.
Ancient Spirits:The four god-like focii of all evil, whose
statues stand in the Black Pyramid. They give Mumm-Ra immortality in
exchange for perpetual servitude, and possess nearly unlimited powers.
However, they require other beings to serve their demands, and cannot
intervene directly in worldy affairs
Mirror Wraith: A phantasm capable of travel
through mirrors. In failure to destroy the Thundercats, the Ancient
Spirits of Evil apparently destroyed him.
