The latest episode of Agatha All Along provided significant excitement for Marvel enthusiasts by referencing a long-anticipated character in the Marvel Cinematic Universe (MCU). This moment unfolded during an early trial on the Witches’ Road, where Teen (portrayed by Joe Locke) and Jennifer Kale (played by Sasheer Zamata) discussed Agatha Harkness. During this conversation, Kale mentioned a child that Agatha once gave up in exchange for access to the Darkhold—a child suspected of being an agent of Mephisto.
Following this revelation, Entertainment Weekly queried showrunner Jac Schaeffer regarding the potential appearance of Mephisto in the MCU. Schaeffer commented, "With these shows, so often there is something that is at once a joke and a wink and a nod, and actually has something legitimate underneath it. As we all know, Mephisto is a character who’s very wrapped into Agatha’s storyline… people have to watch, but we’re always playing with the audience in that way."
Fans had previously speculated that Mephisto was behind Wanda’s imprisonment in WandaVision, but those theories did not materialize. Now, amidst the MCU’s shifting dynamics post-Thanos and Kang the Conqueror, some fans posit that Mephisto could be the next significant antagonist. This namedrop in Agatha All Along and its subsequent recognition in the MCU canon is a moment of vindication for fans who meticulously analyzed WandaVision.
Speculation is rife about potential actors portraying Mephisto within the series. Aubrey Plaza’s character, Rio Vidal, has been linked to Blackheart, a demon born from Mephisto. Additionally, Paul Adelstein’s character, who might be Teen’s father, has raised suspicions with his peculiar behavior and references to dark themes.
Moreover, rumors have suggested that Sacha Baron Cohen might be cast as Mephisto, set to debut in the upcoming Disney+ series Ironheart, which centers on Riri Williams. Although Ironheart may not seem like a typical venue for introducing such a malevolent character, Mephisto’s hallmark unpredictability makes this plausible.
Marvel has declined to comment on Cohen’s potential role in Ironheart or any connections to Mephisto. However, the intrigue around this devilish figure in the MCU continues to build.
