Reign of the Monster is the 16th episode of He-Man and the Masters of the Universe.


Skeletor visits the Torgs and King Von in their cave, promising to free their prince of destruction, Molkrom. In order to accomplish this feat, Skeletor needs the Staff of Avion, which is endowed with the same power of the Elders that imprisoned Molkrom. He kidnaps Stratos to steal the Staff of Avion and successfully frees Molkrom.

Skeletor orders Molkrom to trap He-Man and friends behind a stone wall before riding Molkrom like a steed to Castle Grayskull. There, Molkrom and the Sorceress battle with their powerful magic. Meanwhile. He-Man performs one of his classic punches to break down the stone wall, and appears at Castle Grayskull with a rope to restrain Molkrom. Teela finds where the Torgs are keeping the Staff of Avion so the heroes can imprison Molkrom in a crystal once more.
