For the 1985 incarnation, please see Mumm-Ra (original).
Don't be deceived by appearances, my true form is much more powerful...Ancient Spirits of Evil, transform this decayed form into Mumm-Ra, THE EVER LIVING!
~ Mumm-Ra to Panthro.

Mumm-Ra is an undead sorcerer and the main villain of the 2011 ThunderCats series. Like his 1985 counterpart Mumm-Ra is the bound servant of the Ancient Spirits of Evil. His species is initially unknown, but he eventually reveals himself to be a humanoid vampire bat.


Mumm-Ra the Ever-Living 2011

Mumm-Ra, The Ever Living!

Little is known about Mumm-Ra's origins. However, at some point in the distant past Mumm-Ra commanded a fleet of warships that were combing space for Power Stones - stones of immense power that would make Mumm-Ra invincible. On his ships were several enslaved anthropomorphic animal species - including Cats, Birds, Dogs, Monkeys, Jackals, and Lizards that did Mumm-Ra's will. 

After Mumm-Ra destroyed the Plunn-Darr star system to create material that would allow him to forge a very powerful sword, the Cat leader Leo lead a revolt against Mumm-Ra. Mumm-Ra's ship crashed on Third-Earth, and Mumm-Ra sealed himself in his sarcophagus. The various free animal species divided the Power Stones amongst themselves and proceeded to settle Third Earth.

For the next several millennia Mumm-Ra remained in hibernation. When he judged it safe he emerged from hibernation. Gathering willing allies, Mumm-Ra began a program to conquer Third Earth and re-enslave the various animal species living on Third-Earth.


This version of Mumm-Ra is shown to be just as vicious, ruthless, indignant, sadistic, and callous as his 1985 counterpart. This version of Mumm-Ra is shown to be seeking to impose order on a disorderly universe, unlike his 1985 counterpart who was only interested in obtaining power for himself and the Ancient Spirits of Evil, however, he is willing to kill billions of individuals to achieve his goals.


You are but insects... TO THE POWER OF MUMM-RA! THE EVER-LIVING!!!
~ Mumm-Ra
