ThunderCats S01E64 - The Shifter

Vultureman creates a device that shifts minds and bodies. He givesPanthro Snarf's body, and gives Snarf Panthro's Body. He also shiftsLion-O and Wilykat, and thus makes the Sword of Omens unusable. Eventually, Vultureman shoots the sword, and it causes a reaction that restores all the Thundercats to their rightful bodies.
