fourth member, "Xander", who had been forced to leave the band due to an outbreak of hives, later running the band's fan club. The group is depicted as having embraced all that fame has had to offer them, with Thorn having a tranquillizer gun set aside for her specifically, while a rival group known as "The Jinx Gals" are also referenced, of whom the Hex Girls deride as a rip-off of their own act. Potential spin-off television series Upon the release of Scooby-Doo and the Witch's Ghost, Warner Bros. expressed interest in the development of a spin-off television series revolving around the characters, to be developed by the film's writers Rick Copp and David A. Goodman. Although it went unrealized, elements of this series were adopted into subsequent films featuring the characters, and in February 2019, Copp confirmed he had spoken further to Cartoon Network with regards developing the television series, with Hale, Wiedlin and Brooks all expressing interest in reprising their roles, with Brooks citing MeToo as "even more of a bolster for the argument that we should be trying to revive these characters". Other appearances In the final issue of Scooby-Doo! Team-Up, serving as the final installment of the Crisis of Infinite Scoobys arc (a title in reference to Crisis on Infinite Earths), being a crossover between the various incarnations of Mystery Incorporated from The 13 Ghosts of Scooby-Doo, A Pup Named Scooby-Doo, What's New, Scooby-Doo?, the Scooby-Doo film series, Shaggy & Scooby-Doo Get a Clue!, Scooby Doo! Mystery Incorporated, Be Cool, Scooby-Doo! and Scooby Apocalypse, the Hex Girls are revealed alongside Flim-Flam, Robi and Red Herring to have been controlling a gigantic Scrappy-Doo on the behest of Vincent Van Ghoul against the various incarnations of Mystery Incorporated, being upset that the Scooby Gang were allowed to have their characters evolve over time and continuities and gain more adventure and fame, and having been cast aside to be forgotten. After being questioned as to the absence of the real Scrappy-Doo from the plan, Thorn notes "that mutt [is] too annoying, even for us!", before a pack of various versions of Scrappy-Doo turn up to fight all incarnations. Development The Hex Girls co-creator Rick Copp has cited Josie and the Pussycats as a partial inspiration in creating the characters. Reception The Hex Girls were immediately embraced by fans of Scooby-Doo, and have gone on to be considered cult-classic characters.
