The animation sequence of Queen Angella and Glimmer lifting off to fly into action is reused from Return of the General (1986). Even the dialogue is the same, although it has been re-recorded and the images are flipped horizontally so that the characters now fly off in the opposite direction.
The animation of She-Ra slicing the Annihilator in half while Catra parachutes to safety is reused from Return of the General (1986), in which Hordak was the one who escaped instead of Catra.
The sequence in which Madame Razz casts a spell with the aid of the Twiggets was previously used, albeit with different Twiggets, in Beast Island (1985) and The Wizard (1985).
