Revenge is Never Sweet

As Prince Adam and Teela attempt to fix a broken-down Attak Trak in the desert, Orko stumbles upon the wizard Kothos, who was transformed into a sand slug by Evil-Lyn in the earlier episode "The Witch and the Warrior". He turns him back to his true form, but has made a mistake as Kothos captures the heroes and offers them to Skeletor in return for his second-in-command, Evil-Lyn, upon whom Kothos is determined to enact revenge.
