Six episodes from Season 1 of the 1980s animated series about the battles and adventures of the strongest man in the world. In 'The Curse of the Spellstone', Skeletor and Evil-Lyn steal the Spellstone from the Temple of the Fire People, causing a terrible storm which Evil-Lyn then falsely attributes to the Royal family having angered the Elders. In 'The Time Corridor', He-Man and his team must travel back in time to save Castle Grayskull from past destruction by Skeletor and his cronies. 'The Dragon Invasion' sees Skeletor and Beast Man steal the eggs of a dragon and hide them in the courtyard of the Royal Palace. When they hatch out and attack the palace, He-Man and his fellow warriors must use all their powers to get rid of them, leaving Castle Grayskull wide open to invasion by Skeletor. In 'A Friend in Need', an evil sorcerer uses his magic to beguile himself to the daughter of an inventor, Zicran, who has delivered a Transmutator machine to the Royal Palace. Cleverly worming his way into the daughter's trust, the sorcerer uses her to help him steal the Transmutator, leaving the Heroic Warriors to rescue both the machine and the inventor's daughter from the sorcerer's evil clutches. In 'Masks of Power', two travellers visiting an ancient temple steal the Masks of Power, which are imbued with ancient and evil spirits. They ask Skeletor if they can join forces with them, but he insists that they prove themselves by bringing him the Sword of the Ancients from inside Snake Mountain. In 'Evil-Lyn's Plot', Evil-Lyn disguises herself as a young girl lost in the forest in order to steal the precious mineral Coridite, the substance used to make He-Man's harness, from the fortress of the Widgets.
