- For the article about the 1980's version of this weapon, see Sword of Plun-Darr.
Sword of Plun-Darr is one of the most powerful weapons ever to exist. It possesses phenomenal magical powers which originate from the Power Stones which is embedded in its hilt.
When not active, the Sword exists as a short dagger and is usually carried inside the Gauntlet of Plun-Darr. When called to action, the blade extends to form a much longer sword. It is capable of shooting incredibly powerful energy beams as well as deflecting any offensive fire.
Centuries ago, Mumm-Ra, wanting to attain control over the entire universe, consulted the Ancient Spirits of Evil to help him achieve ultimate power. Under their orders, Mumm-Ra destroyed the Star of Plun-Darr and its remains were used to create the ultimate weapon of destruction, the Sword of Plun-Darr. It was forged by the Blacksmith possessed by the Ancient Spirits themselves.
Armed with the Sword of Plun-Darr, Mumm-Ra only awaited the retrieval of the War Stone so that he could embed it into his new weapon and acquire the power of all the four power stones. Upon seeing Mumm-Ra's ruthlessness and insatiable lust for power, his two most trusted commanders, Leo and Panthera decided to stop him. Gathering the debris left from the forging of the Sword of Plun-Darr, they employed the same Blacksmith to forge them another sword and gauntlet, giving birth to the Sword of Omens. Embedding the War Stone retrieved by Tygus into the hilt of the Sword of Omens, Leo was able to use the now powerful blade to defeat Mumm-Ra.
After Mumm-Ra's defeat and the subsequent crashing of his spaceship on Third Earth, all the surviving creatures that were enslaved by him were freed and settled on the new planet. The Sword of Omens remained in Leo's possession and was passed down from one Lord of the ThunderCats to the next, eventually being inherited by Lion-O after the death of his father Claudus.
The crash of the spaceship caused the Sword and Gauntlet of Plun-Darr to be scattered on Third Earth where they both ended up sinking to the bottom of a swamp. The two weapons remained in the depths of the murky waters for many centuries until Ratilla discovered them while scavenging for food in the swamp. With the powerful sword in his possession, Ratilla and the other Rats rose to prominence, taking what they though was rightfully theirs by any means necessary. Before Ratilla's discovery, the Rats lived off the other animal's leftovers, feeding off scraps in the swamplands, barely surviving while species such as the Cats thrived and prospered for generations.
Seeing Ratilla's blatant abuse of power, the ThunderCats sent the wizard Jaga to put an end to Ratilla's reign of terror. Armed with the Sword of Omens and his own powerful magic, Jaga was able to defeat Ratilla. To keep the Sword of Plun-Darr out of evil's hands, Jaga put a curse on it and plunged it into the earth, allowing a mountain to grow over it like a scar, burying it forever.
Many centuries later, Ratilla's descendent Ratar-O, wanting to return the Rats to the position of power that they enjoyed during Ratilla's reign, organized a massive mining operation on Mount Plun-Darr to retrieve the Sword of Plun-Darr. The task was made difficult by the curse put on the sword by Jaga which spelled death for anyone who tried to extract it. Not wanting to risk his own hide, Ratar-O employed hundreds of Thunderian Slaves that he bought from the Lizards to dig for the sword, letting his right hand man Mordax and other Rats oversee the excavation.
After learning of the mining operation from Pumyra, one of its escapees, Lion-O, Panthro, and Pumyra headed to rescue the slaves while Tygra and Cheetara tried to locate the Sword and the Gauntlet of Plun-Darr. While Tygra and Cheetara succeeded, Lion-O and his gang were captured and brought before Ratar-O who decided to execute the ThunderCats.
Fortunately, Tygra and Cheetara's action of removing the Sword and Gauntlet of Plun-Darr triggered an earthquake which caused Ratar-O's palace to collapse, burying everyone under a pile of rubble. As Lion-O emerged from the debris, Ratar-O attacked him. Mordax, who had initially captured the ThunderCats, had a change of heart and threw Lion-O the Sword of Omens and the Gauntlet of Omens, allowing him to defeat Ratar-O who fled underground, never to be seen again.
The ThunderCats' victory celebration was short lived as Mumm-Ra, who could sense the presence of the Sword of Plun-Darr, was able to home in on its location. Despite Lion-O and Pumyra's efforts, Mumm-Ra succeeds in regaining possession of the Sword of Plun-Darr.
