Mephisto Was The Center Of Much Speculation During WandaVision
The Demon Was Theorized To Be The Main Villain
WhenWandaVisionpremiered in 2021, it was the first Disney+ MCU show produced by Marvel Studios, and there was a great deal of expectation that it would have major ramifications on the larger franchise. While that didn’t quite turn out to be the case - aside from finally establishing Wanda as Scarlet Witch - it did feature a storyline inherently tied to magic. As a result, many theorized the main villain ofWandaVisionwould be revealed as Mephisto.The speculation became so pervasive that even those without any comics knowledge of Mephisto had seen his name mentionedin fan conversations.
However, by theend ofWandaVision, Mephisto wasn’t so much as name-dropped. Instead, Agatha turned out to be the closest thing to a villain inWandaVision, and many of the curious things that happened in WestView were the result of her meddling, rather than, as viewers speculated, Mephisto. ThoughWandaVisionis widely regarded as one ofthe best MCU TV shows,there was still some disappointment that one of Marvel’s most powerful villains wasn’t even mentionedin the show. However,WandaVision’ssequel series is now paying off the rampant speculation.
Agatha All Along Episode 3 Confirms Mephisto Exists In the MCU
The Demon’s Name Is Finally Dropped In A Marvel Show
DuringAgatha All Alongepisode 3, the witches of Agatha’s coven discover that asigil has been placed on Joe Locke’s character, and they seem to think Agatha is behind it. In a moment alone, Jennifer Kale warns Teen to be careful around Agatha, that there are rumors she traded her son, Nicholas Scratch, for the Darkhold. She says no one knows what happened to him, andhe could be an"agent of Mephisto.“It’s the first time Mephisto has been mentioned by name in the MCU and confirms the demon’s existence.
Beyond that, we don’t know much else about the MCU’s iteration of Mephisto. In the comics, he’s a demon that rules over a pocket dimension he calls “Hell,” similar to Dormammu and the Dark Dimension from 2016’sDoctor Strange. However,the fact that someone could be an “agent” of Mephisto indicates he utilizes people, most likely desperate magic users, to do his bidding on Earth. Further, now that we know someone can be an agent of Mephisto, it begs the question of whether one of the characters inAgatha All Alongis working for the demon - though that remains a mystery for now.
When Mephisto Could Finally Appear In The MCU
Agatha All Along Could Reveal An Agent Of Mephisto
Now thatAgatha All Alongepisode 3 has introduced the concept of a person working for Mephisto, it’s possible the show reveals one of the main cast to secretly be his agent. Aubrey Plaza’sRio Vidal is the most obvious contender, given she’s already proven to be an antagonist of sorts for Agatha. In fact, she may have sought out Agatha on Mephisto’s behalf, since it hasn’t been explained why she showed up in WestView in episode 1.
If not Rio, Teen is also a possibility. If Mephisto needs “agents” to carry out his bidding, it’s possiblehe could be trapped in Hell, and has enlisted Teen to walk the Witches' Road to free him. After all, Teen’s reasoning for walking the Witches' Road was a simple explanation about wanting more power. The vagueness of it seems to hint that he’s hiding something beyond what the sigil is forcing him to keep secret. But, there’s always the possibility that the agent of Mephisto is someone unexpected, like Jennifer Kale or Lilia Calderu.

If an agent of Mephisto appears inAgatha All Along, it’s likely to set up an appearance from the demon in a future MCU project. In 2022, there were reports thatSacha Baron Cohen would play Mephisto inIronheart, which is set to release next year. How Mephisto factors into the story ofIronheartis unclear, but the villain is a Marvel character called The Hood, who has a magical demonic cloak.
