|Sword of Plun-Darr|
|List of all weapons & other items|
The Sword of Plun-Darr is a mighty blade with powers that rival those of the Sword of Omens. It is a double-bladed sword with a snake handle which can shrink into its handle when not in use. The sword was once wielded by Ratilla, the warlord ancestor of the Mutant Ratar-O.
A long time ago on Thundera, Ratilla tried to steal the Treasure of Thundera using the Sword of Plun-Darr. However, he was stopped by a young Jaga who was at that time the Lord of the ThunderCats. Jaga defeated Ratilla and threw the Sword of Plun-Darr into a deep canyon on Thundera, sealing it in molten rock and preventing it from ever falling into the wrong hands. Unfortunately, the power of the sword was so great that it could not be contained and eventually it was this power that led to the destruction of Thundera, causing the ThunderCats to flee their home planet and seek refuge on Third Earth.
Many years later when Thundera starts to re-form, Mumm-Ra manages to obtain the Sword of Plun-Darr and it becomes a part of his arsenal.
