Trivia: Space Ghost
- Hey, It's That Voice!: Not only Laugh-In's Gary Owens as Space Ghost himself (he would later return to H-B as Commander Feral), but Jace is a grown-up Jonny Quest (Tim Matheson) and the villain Metallus is Rukk the Android and Lurch (Ted Cassidy).
- Name's the Same: Spider-Woman (no relation to the Marvel superheroines). That may be the reason why her name is changed to Black Widow in SGCTC.
- A villainess named Black Widow appeared in the original Space Ghost show (first appearance: "The Web").
