Man-At-Arms uses the Sorceress' Book of Magic to reveal that the Dark Dimension is closely linked to Eternia's world. Orko wanders in and sees the book, and uses a spell to bring the impish Daimar to Eternia. An eerie mist suddenly hovers over the Royal Palace. Man-At-Arms, Adam, and Cringer go to the lab and discover that Daimar's picture is missing from the book. Soon, the magical mist reaches Snake Mountain, and Skeletor initially blames Evil-Lyn. Evil-Lyn goes to the Royal Palace, where she steals the magic book, and uses it to challenge Skeletor, but he quickly defeats her. He-Man, Battle Cat, and Teela get to Castle Grayskull, where the now-giant Daimar reaches the castle. Skeletor and Evil-Lyn arrive in the Basher and attempt to control Daimar. Daimar declares that it is his destiny to bring his demon world to Eternia. Skeletor and Evil-Lyn attack Daimar, but he defeats them easily. Daimar decides to become good and returns to the Dark Dimension.
