Trivia

 * Daphne and Velma are portrayed as biracial in this series, both from their maternal side, with Daphne being Hispanic American and Velma being Japanese American.
 * Save for Scooby and Shaggy (who kept their regular voice actors), most of the cast is voiced by celebrity actors instead as the developers wanted to distinguish it from the main series by reflecting it is a darker incarnation.
 * Despite that, Grey Griffin (Daphne's regular voice actress) and Jennifer Hale (Thorn's regular voice actress) still provide additional voices for the series, with the latter also reprising her role as Amber from The Alien Invaders.
 * While the developers still opted to make one of the lead's relatives, they opted to make Daphne's this time as they justified that making Fred's relatives evil again (like Mystery Incorporated and Be Cool) would get repetitive as they also stated that making either Shaggy's or Velma's would feel weird.
