Agatha All Along” & WandaVision Creator Jac Schaeffer Reveals Thoughts on Fantastic Four & Mephisto Fan Theories
Jac Schaeffer, the brilliant mind behind Marvel Studios’ hit series WandaVision and the song “Agatha All Along,” has finally weighed in on some of the fan theories that have sparked discussions across the internet—particularly those involving the Fantastic Four and the long-rumored Mephisto. With her ability to blend humor, heart, and high-concept storytelling, Schaeffer has become a pivotal figure in the Marvel Cinematic Universe (MCU), and fans have been eager to hear her thoughts on how WandaVision’s intricate narrative ties into larger MCU lore.
The Emmy-winning song “Agatha All Along,” written by Robert Lopez and Kristen Anderson-Lopez, became an instant phenomenon when it was revealed that the series’ quirky neighbor Agnes (played by Kathryn Hahn) was actually the powerful witch Agatha Harkness. The song’s popularity was not just due to its catchy tune but also because it confirmed long-held suspicions that Agatha had been manipulating events in Westview all along.
Jac Schaeffer, as the head writer and executive producer of WandaVision, played a crucial role in making Agatha Harkness a standout character. Fans praised the revelation, and many began theorizing about how Agatha’s storyline could open the door to other iconic Marvel characters, including Mephisto and the Fantastic Four.
In a recent interview, Schaeffer expressed her delight at the fan engagement, noting, “It was so fun to see everyone reacting to ‘Agatha All Along’ and all of the theories that followed. The fans are incredibly smart and creative, and they come up with connections that even surprise us in the writers’ room.”
One of the most persistent fan theories surrounding WandaVision was that the show would introduce the Fantastic Four, Marvel’s First Family. Fans pointed to Monica Rambeau’s mention of an “aerospace engineer” in Episode 7 as a potential reference to Reed Richards (aka Mr. Fantastic), fueling speculation that the iconic superhero team might be introduced via the series. However, the theory never came to fruition by the show’s end.
When asked about the Fantastic Four theory, Schaeffer acknowledged the excitement but clarified that WandaVision was never meant to serve as the Fantastic Four’s introduction into the MCU. “The Fantastic Four is such an important part of Marvel’s history, and while I think it’s great that fans were drawing those connections, that wasn’t the story we were telling in WandaVision,” she explained. “Our focus was always on Wanda’s journey, her grief, and how she was coming to terms with everything she had lost.”
However, Schaeffer did not dismiss the possibility of the Fantastic Four making their MCU debut in the future. “I’m just as excited as everyone else to see what Marvel has in store for them. There’s so much potential, and I think when the time comes, it’ll be something truly special,” she added.
The Fantastic Four are slated to be introduced in their own upcoming MCU film, currently in development by Marvel Studios under the leadership of Kevin Feige. Fans are eagerly awaiting further details on casting and storylines, and Schaeffer’s remarks suggest that their introduction will happen on a grander scale than a subtle Easter egg in WandaVision.
Perhaps the most pervasive and persistent theory among WandaVision fans was that Mephisto, the Marvel Comics devil-like villain, was pulling the strings behind the events in Westview. As early as Episode 1, fans combed through every scene looking for hints of Mephisto, convinced that he was the true villain manipulating Wanda Maximoff (Elizabeth Olsen). The theory gained further traction due to Mephisto’s association with Wanda and her children in the comics.
Schaeffer admitted that she was aware of the Mephisto theory from the beginning but was surprised by how deeply it resonated with the fandom. “I think it’s a testament to how invested the fans are in the MCU and how much they know about the comic lore,” she said. “Mephisto is a great character, but he was never part of the story we were telling in WandaVision.”
While Mephisto did not make an appearance in the series, Schaeffer did not rule out the possibility of the character showing up in future MCU projects. “I can’t speak to what Marvel has planned, but there’s always room for new and exciting characters to be introduced,” she teased. “The beauty of the MCU is that it’s constantly evolving, and there are always more stories to tell.”
Marvel Studios has been known to keep fans guessing, and with characters like Agatha Harkness now part of the MCU, many still believe that Mephisto’s arrival is inevitable. Agatha’s dark magic and her history with characters like Mephisto in the comics only fuel the speculation that the devilish villain could appear sooner or later.
Following WandaVision, it was announced that Kathryn Hahn’s Agatha Harkness would be returning in her own spinoff series, Agatha: Darkhold Diaries (formerly titled Agatha: Coven of Chaos). Schaeffer is set to return as the showrunner, and fans are eager to see how Agatha’s character will evolve in the series and how her story might intersect with other characters in the MCU.
When asked if Agatha: Darkhold Diaries could bring in the Fantastic Four or Mephisto, Schaeffer remained tight-lipped but did hint at exciting developments. “I think Agatha’s story is far from over, and we’ve only just scratched the surface of what she’s capable of. There’s definitely more to explore with her character, and I can’t wait for fans to see what’s next.”
Jac Schaeffer’s insights into WandaVision’s fan theories reveal the careful balance between fan expectations and the creative vision behind the show. While the Fantastic Four and Mephisto fan theories didn’t come to fruition in WandaVision, Schaeffer remains optimistic about the future of these characters in the MCU.
As Marvel continues to expand its universe, fans will undoubtedly keep theorizing and looking for clues in every corner of the MCU. For now, Schaeffer and the team behind WandaVision are focused on telling the stories they’ve set out to tell, while leaving the door open for future surprises.
