Baron Grod's character model is a reused and recolored version of Danavas from Valley of Power (1983).
The comical sequence in which Cringer tries to hide around a corner during the transformation sequence was first used by writer Larry DiTillio in The Dragon's Gift (1983).
The background used as Baron Grod's throne room is reused as King Paw's throne room in The Cat and the Spider (1984).
In the storyboards, Growler is not a robotic dog but drawn to resemble one of Zalt's Mechacats from Orko's Missing Magic (1983).
