ThunderCats Encyclopedia - Character Overview header

Mumm-Ra the Everliving, evil devil priest of Third Earth, has lived for centuries, since the planet was known as First Earth. With his loyal hound Ma-Mutt, Mumm-Ra was the source of all evil on the planet, residing within his black pyramid and drawing vast amounts of power from The Ancient Spirits of Evil. Mumm-Ra’s decayed form could be transformed into that of Mumm-Ra the Everliving by a chant which went ‘Ancient Spirits of Evil, transform this decayed form to Mumm-Ra the Everliving!’ In his Everliving form Mumm-Ra became even more powerful, but was forced to return to his sarcophagus within his pyramid and rest after a time. Mumm-Ra’s greatest weakness however, was that he could not stand to see his own reflection, and look upon all his evil.
