The character model of the adult David was reused as an extra on a balcony in The Red Knight (1985).
Count Marzo is one of the rare Filmation based villains who makes more than one appearance. He returns in The Eternia Flower (1985) and Search for a Son (1985) and so does his henchman Chimera, although he was redesigned. Marzo also uses Pterror-dactyls again in his third appearance, this time colored blue rather than brown.
Count Marzo uses the Well of Forgetfulness again in Search for a Son (1985), although it's location on Eternia has changed.
The script identifies Marzo's vehicle as a 'Doom Buster' even though a different design was used for the vehicle of the same name used by Skeletor.
The animation of He-Man blowing away the freezing fog would be used again in The Rarest Gift of All (1984), Betrayal of Stratos (1984), A Trip to Morainia (1985), Just a Little Lie (1984), The Greatest Show on Eternia (1984) and Happy Birthday Roboto (1985).
