For the article about the 1980's version of this character, see Mumm-Ra.

Mumm-Ra is the main antagonist in the ThunderCats (2011) cartoon series and the mortal enemy of the ThunderCats themselves.

An ancient force of evil and powerful sorcerer, Mumm-Ra craves power and his sole ambition is to achieve order, his order, within the entire cosmos. In order to achieve his goal he requires all four of the Power Stones so that his own power is multiplied infinitely.

Many centuries ago he had enslaved a number of Animal species to do his bidding, including the Cats, whom he trusted more than the other races. Armed with this massive Animal army and advanced technology, Mumm-Ra scoured the galaxy in his Black Pyramid and plundered many planets in his quest to obtain the Power Stones.

With three of the four stones in his possession, he was commanded by the Ancient Spirits of Evil to destroy the Star of Plun-Darr and use its remains to forge the Sword of Plun-Darr in which the stones can be housed.

The destruction of the Star of Plun-Darr results in the elimination of the ten planets orbiting it, including three with life. This act shatters the delusions of his most loyal commander Leo and he along with his second commander Panthera and the Animal slaves stage a rebellion against Mumm-Ra. They succeed in locking the evil warlord in his sarcophagus as their spaceship crashes on Third Earth. The survivors distribute the Power Stones among themselves and head of to start a new civilization.

Many thousands of years later, Mumm-Ra preys upon the paranoid and power-hungry Grune and uses him to free himself. The two mastermind the downfall of Thundera with the help from the Lizard Army. In the guise of Panthro, Mumm-Ra murders King Claudus while his army and Grune ravage the Cats' empire.

In order to regain the Power Stones as well as the Sword of Plun-Darr, Mumm-Ra employs Slithe, Addicus, and Kaynar among others in his growing army. He also resurrects the revengeful Pumyra and plants her as a spy among the ThunderCats.

Eventually Mumm-Ra gains possession of the Sword of Plun-Darr as well as the Tech Stone, thanks to Pumyra, and also gains a new ally in the form of Vultaire.


Mumm-Ra is an absolute master of magic and sorcery and possesses an unlimited knowledge of them. The embodiment of evil, he is virtually indestructible and can transform himself into the Ever-Living form in which he grows not only in size but in powers as well.

In his Ever-Living form, Mumm-Ra has superhuman strength as well as able to shoot powerful energy bolts and capable of flying.

Mumm-Ra is also able to transform himself into various forms to trick his opponents.


Mumm-Ra's immense power comes at a price. He can only maintain his power for a short time, after which he must return to his sarcophagus to rest and rejuvenate. The more power he expends, the quicker he tires.

Mumm-Ra is also susceptible to bright sunlight and burns quickly in its presence.

Weapons and EquipmentEdit

Apart from his own magical powers, Mumm-Ra wields the mighty Sword of Plun-Darr and the Gauntlet of Plun-Darr, the latter of which can turn into the Armor of Plun-Darr when fitted with the Power Stones and give him even further protection.



  • While similar in many aspects to his 1980s counterpart, the 2011 version of Mumm-Ra sports two giant wings in his Ever-Living form.
  • While the 1980s Mumm-Ra's main weakness was not being able to stand the sight of his own reflection, the 2011 Mumm-Ra's weakness is bright sunlight, similar to a vampire.
