Original Airdate: ?/?/1984
Caught in desert winds during an expedition for Man-At-Arms, He-Man and Orko look for shelter. He-Man bursts through ruin walls that lead to an ancient Silcon laboratory. Traps separate Orko and He-Man, and Orko turns on the time wheel that activates a gate bringing King Tamask, former ruler of Eternia, to the future. Orko says that Randor is king, and Tamask vows to reclaim his throne.
Refusing to trust Orko and He-Man, Tamask rides his lizard beast toward the Royal Palace. He attacks King Randor and Queen Marlena hoping to reclaim his throne, but He-Man drives him away. He-Man and Orko follow Tamask back to the Silcon ruins, where he turns statues against them. One of the statues takes Tamask prisoner, and He-Man frees him by trapping the statue in a flood of sand and spinning it until it erodes.
Tamask realizes He-Man is a friend and takes He-Man's fear of fighting to heart. Tamask returns to his rightful time in history. Orko throws Tamask's club into the vortex, causing an explosion that destroys the Silcon ruins.
