Original Airdate: ?/?/1984
The visiting Lord Todd charms the Royal Family and takes Teela back with him to his desert home at Castle Star. The Sorceress summons Man-At-Arms to Grayskull while Adam investigates a tremor by the castle ruins beyond the Palace. He-Man discovers the underground creature Moak. Lord Todd reveals that he wants Teela to be the queen in his intergalactic, life-size chess set, a collection of prized creatures from all over the universe.
Todd reveals himself to be an alien monster, with plans to take Teela back to his evil dimension. Man-At-Arms arrives only to be captured by Todd's robots. Teela surrenders to Todd for the sake of her father. When He-Man enters the castle and frees Man-At-Arms, Todd's Eternium Maze slows him down. Moak accidentally surfaces inside the castle, and he helps He-Man and Man-At-Arms reach Todd's control room. Todd opens the Star Gate to his dimension and takes Teela with him, but He-Man holds the Star Gate open long enough for Man-At-Arms and Teela to return to safety. The Star Gate, Lord Todd, and Castle Star vanish.
