Beast Man and Trap Jaw were Skeletors assistants in the original script but the Filmation Bosses asked Robert Lamb to replace them with Two-Bad as Mattel were demanding exposure for their latest figures.
Robert Lamb was ordered by Filmation Bosses to make heavy revisions to the original script because they felt Skeletor was portrayed too evilly in it.
John Erwin voices the character of Zagraz in a voice similar to Ed Wynn.
Zagraz previously appeared in The Cosmic Comet (1983) and his character model was reused as the Gatekeeper in The Magic Falls (1985).
The sequence of the tower falling and He-Man catching it was first seen in Return of the Gryphon (1983) and when He-Man catches the Life Bringer in Journey to Stone City (1985).
