The character breakdown for The Chilling Adventures of Sabrina's protagonist confirms that Sabrina the Teenage Witch will have a proper rebel streak on the Riverdale spinoff series. Chilling Adventures of Sabrina will be based on the supernatural horror/coming of age comic book series of the same name, which was created in 2014. The Archie Comics offshoot was spun-off from the Afterlife with Archie series and co-created by Riverdale showrunner Roberto Aguirre-Sacasa (who is also the Chief Creative Officer of Archie Comics).
Like Riverdale, The Chilling Adventures of Sabrina TV show will air on The CW and explore the darker underbelly of the Archie universe. Whereas Riverdale features (seemingly) human threats like the Black Hood killer (the big bad of season 2 thus far), Chilling Adventures of Sabrina will follow Sabrina as she does battle with dark supernatural forces that endanger the lives of those she loves and cares about (herself included). The actual breakdown for the Sabrina character specifically mentions that her ongoing battle against "the Forces of Darkness" is very much part of her daily life as a teenager.
Said Chilling Adventures of Sabrina breakdown, which was obtained by That Hashtag Show, further specifies that the role of Sabrina is open ethnicity, female, and will "play" the age of sixteen. You can read the description of Sabrina in full below:
Sabrina is an half-human, half-witch, empowered young woman just beginning her dark education as a sorceress, even as she tries to maintain a normal life as a sophomore at Baxter High. Sabrina's intelligent, compassionate, and brave to the point of recklessness. She is fiercely loyal to her family and friends; wickedly funny and in the middle of a star-crossed romance with her classmate Harvey Kinkle. She challenges witch-doctrine at every turn. She is all that stands between us an the Forces of Darkness that threaten our world.
This breakdown lines up with the details that were revealed about the show, when Aguirre-Sacasa posted an actual page from The Chilling Adventure of Sabrina pilot script online. It sounds as though Sabrina and Harvey will be the two main leads in the series, with other characters serving in a supporting capacity. By comparison, Riverdale is more of an ensemble piece that features four protagonists (Archie Andrews, Betty Cooper, Jughead Jones, and Veronica Lodge) - five, if you count the eponymous town itself.
Her superpowers aside though, Sabrina sounds like the sort of teenager who would feel right at home hanging out with Archie and his friends on Riverdale. The latter show has yet to incorporate overt fantasy elements into its narrative, but the groundwork is arguably in place for Riverdale to go full supernatural one day; maybe even with a special appearance by Sabrina herself. Of course, The Chilling Adventures of Sabrina needs to find its teenage witch and make it past the pilot stage of development, before we can start having a serious discussion about the possibility of Sabrina paying a visit to "The Town With Pep".
The Chilling Adventures of Sabrina doesn't have an official launch date yet, but is expected to premiere during the 2018-19 TV season.
