Madelaine Petsch is trading Riverdale’s small town drama for a whole new kind of chaos. The ‘Riverdale’ alum has officially joined the cast of ‘American Horror Story: 13‘, and the internet is buzzing about what her character means for the show’s biggest crossover season yet.
New photos from gave fans their first look at several new and returning characters in ‘American Horror Story: 13’, the upcoming all-star crossover season from Ryan Murphy and Brad Falchuk. Petsch’s addition to the cast is one of the season’s more intriguing surprises, and it’s easy to see why fans are already speculating about her role.
Madelaine Petsch’s ‘American Horror Story’ Role Revealed as Kira
Among the newcomers joining ‘AHS: 13’ is Petsch, who will play a character named Kira, described as a woman obsessed with the number thirteen. That obsession fits neatly with the season’s entire premise, which leans hard into the number as both a title and a thematic anchor.
Nobody was expecting this character to stick around for the long haul, but Petsch reportedly makes a welcome addition to the ever expanding ‘AHS’ cast list as the mysterious Kira, whose true identity is revealed in the opening scene of the premiere. That kind of early reveal has already sparked plenty of chatter among longtime viewers trying to piece together how she connects to the larger mythology.
Petsch is best known for playing Cheryl Blossom on The CW’s ‘Riverdale’, a role she held from 2017 until the series ended in 2023 after seven seasons. Stepping into the horror anthology world marks a notable shift for the actress, who has spent years building a following well beyond her television work.
‘American Horror Story: 13’ Cast Brings Back Fan Favorite Characters
Petsch’s Kira is joining one of the most stacked ensembles in the show’s history. The season brings back a number of characters from previous seasons, including Constance Langdon, Cordelia Goode, Madison Montgomery, Marie Laveau, Rubber Man, Twisty the Clown, and Kai Anderson, with FX teasing even more surprises still to come.
The cast is packed with ‘American Horror Story’ veterans, with Sarah Paulson, Evan Peters, Angela Bassett, Kathy Bates, Emma Roberts, Billie Lourd, Gabourey Sidibe, Leslie Grossman, Joey Pollari, and Jessica Lange headlining the season. Newcomers like Petsch are joined by Avantika, Jamie Brewer, Elle Chapman, Berto Colon, Alex Consani, Frances Conroy, Mat Fraser, Seth Gabel, Orlando Jones, Paul Anthony Kelly, John Carroll Lynch, Tig Notaro, Fedor Steer, Mena Suvari, Zach Villa, and John Waters.
The returning stars aren’t just making cameos either. Sarah Paulson is set to play Cordelia Goode, Jessica Lange will play Constance Langdon, Evan Peters will play Kai Anderson, and John Carroll Lynch will reprise Twisty the Clown from ‘Freak Show’, with many actors juggling multiple roles from the show’s past. Jessica Lange is reprising Constance Langdon, Sister Jude Martin, Fiona Goode, and Elsa Mars, and may play more than one of those characters within the same scene.
Showrunner Ryan Murphy has been open about how ambitious this structure gets. Murphy revealed that Evan Peters plays two different characters talking to himself in the same scene, calling the editing process both tricky and fun, hinting at just how layered this reunion season really is.
Season 13 Premiere Date and Episode Format
‘American Horror Story: 13’ premiered on FX and Hulu, streaming internationally on Disney Plus, and consists of 13 half hour episodes, with FX taking a fast release approach designed to wrap the entire season before Halloween. Premiere night and the following week each featured three episodes, followed by pairs of new episodes each Thursday leading up to the thirteenth and final episode.
The shortened episode format is a departure from the show’s usual hour long structure, and it seems intentional given the sheer size of the ensemble. The teaser itself offered no scenes from the upcoming season, instead showing cast members walking through a spooky location dressed in character and posing for the camera, building anticipation without giving too much away.
Murphy has described the season in sweeping terms. He called ‘AHS 13’ a greatest hits season, positioning it as a culmination of everything the anthology has built over more than a decade.
Fan Reactions to the Growing Ensemble
The reveal of Petsch’s casting, alongside other newcomers, has fueled comparisons to major franchise crossover events. Some outlets have described the season as an Avengers Endgame type event for the long running ‘AHS’ universe, given how many past characters and actors are converging in one installment.
Not every planned cast member made it to set, either. The show’s official synopsis teased that fans should prepare for a supreme surprise, bringing together an all star cast many of whom are reprising fan favorite roles, though Ariana Grande was notably absent from the final lineup after scheduling conflicts.
Alex Consani’s debut as the witch Morwenna has also generated significant buzz alongside Petsch’s arrival. Consani plays Morwenna in a coven storyline that pulls heavily from ‘Coven’, the show’s third season originally set in New Orleans in 2013, giving longtime fans another thread to follow alongside Kira’s mysterious arc.
With so many returning faces and new additions like Petsch woven into the story, ‘American Horror Story: 13’ seems designed to rewards longtime viewers who have followed the anthology since Murder House. Whether Kira ends up as a fleeting cameo or a character who reshapes the season’s mythology remains to be seen once more episodes roll out.
What do you think Kira’s obsession with the number thirteen really means for the rest of the season, and where do you think Madelaine Petsch’s character fits into the larger ‘AHS’ mythology?
