Though it is toted as a "collector's item," the first issue of the 13-issue series is hardly that. As the story begins, Skeletor seals the interplanetary gate between Eternia and Etheria to stop Hordak from coming. In the meantime, Adam and Teela are practicing their mid-air fighting skills. The Sorceress alerts Adam to danger, and he rushes to Grayskull. There, he finds Skeletor trying to dig into Grayskull with the Terror Claws of Allocca. Maybe you should re-read that last sentence. Anyway, Skeletor takes Zoar as hostage, and Orko says an incantation for help, and he gets something he didn't bargain for: Hordak and the Horde show up. A battle ensues, and eventually Hordak captures everyone and imprisons them on Etheria. They break free, of course, and, after a brief skirmish with the worm monster, Orko says an incantation to take them all home. They arrive to find Hordak beating Skeletor in a duel of magic. The heroes stop Hordak and he returns to Etheria, while Skeletor curses them for helping.
