Orko is casting a spell in his bedroom, hoping to unleash the power hidden in a crystal. But a Gronk accidentally falls into the crystal, causing an explosion. Later, Orko prepares to perform in front of the king and queen, but his magic fails. Orko feels useless without his magic. At Grayskull the Sorceress determines that the Gronk disappeared with Orko's powers into another dimension, the planet of Omiros. The heroes learn from Tick Tock that the Gronk was taken by the evil wizard Zolt.
After a battle with a giant, He-Man, Battle Cat and Orko meet Zolt, who takes He-Man's sword. The sword shocks Zolt, forcing him to throw it. Zolt conjures up a small army of robot lions, which are easily defeated by the heroes. When He-Man and Orko return to the site of the portal, Zolt attacks. Zolt is defeated and ends up a prisoner of Tick Tock. The portal back to Eternia disappears, leaving the heroes trapped on Omiros forever. After a few attempts Tick Tock recreates the portal and the heroes return to Eternia, where the Sorceress restores Orko's magic.
