Kathryn Hahn’sAgatha Harknesscould come back in 2025, as aMarvel Cinematic Universetheory shows how the character can stop being a ghost. Agatha has become one of the most interesting characters to follow in the MCU. Thanks to Hahn’s impeccable comedic timing and a series of plot twists, she was the breakout character ofWandaVision. Hahn then got the chance to show her potential by leadingAgatha All Along’s cast, and the TV series ended with a major status change for the evil witch, withAgatha being selfless for once and dying.

Despite her death, Agatha is still around in the MCU.Agatha All Along’s endingsaw a ghost version of Agatha team up with Joe Locke’s Billy Maximoff to find his brother, Tommy. While that quest seems like the logical next step for Agatha in the MCU, there is a way for Hahn to return as a version of the witch before then. That possible appearance would come in a2025 MCU movie, and it could lead to Agatha Harkness' return to life thanks to a new Marvel theory.

Recasting 20 MCU Actors In Perfect Roles For James Gunn’s DC Universe

James Gunn has already cast MCU actors in the DCU, and he has teased that more will come, with many Marvel stars being perfect for DC characters.

Sue Storm was seen with a baby on the set ofThe Fantastic Four: First Stepsafter rumors about Sue and Reed’s children, Franklin and Valeria Richards, being in the movie emerged. That could lead toa version of Agatha Harkness from the Fantastic Four’s universe— the movie does not take place in the main MCU Earth — appearing. There are a few reasons for that. Agatha was Franklin’s nanny in the comics. Add that to the movie’s 1960s setting, which fits Agatha’sWandaVisionaesthetic, and the Fantastic Four film being directed byWandaVision’s Matt Shakman, and Agatha’s inclusion looks possible.

MCU Theory: Agatha Harkness Steals A New Body

The New Agatha Harkness Could Have A Tragic Future

Kathryn Hahn’s Agatha Harkness is currently a ghost in the MCU, but the inclusion of an Agatha variant inThe Fantastic Four: First Stepscould change that. The MCU has already shown that characters can possess the bodies of their multiverse variants through the use of dark magic. The Scarlet Witch and Doctor Strange both used that skill inDoctor Strange in the Multiverse of Madness. Adding to that,Agatha All Alongalso showed that ghosts can take over someone else’s body, as Agatha’s mother, Evanora Harkness, took over hers for a short time.

The Fantastic Four: First Stepsis set on another Earth. With Galactus being the movie’s villain, the MCU theory suggests that he could win against the Marvel team and devour their planet. In an effort to escape being killed, Reed Richards and the rest of the Fantastic Four travel through the multiverse and end up on the main MCU Earth, taking the kids' nanny, Agatha, with them. The MCU theory goes on to explain how,after sensing a variant of hers, the ghost Agatha decides to take over her body, with Hahn’s Agatha Harkness coming back to life in 2025.

The Witch Could Appear In Multiple MCU Movies & Shows

Besides a possible role inThe Fantastic Four: First Steps, Agatha should still have plenty to do in the MCU. Even if Marvel does notrenewAgatha All Alongfor season 2, there are potential projects that could use the witch. Agatha has to help Billy find his brother. That could happen in one of many possible projects. A Wiccan series would be the ideal way to go about it.Billy and Agatha could also appear in the Vision seriesto find both Tommy and White Vision in one fell swoop, or a Young Avengers project could be in play.

Based on the MCU theory, Agatha could feel bad for taking over her variant’s body. As such, this could lead the character down a path of redemption, which is in line with her ending inAgatha All Along. If she were to take her variant’s body to stop being a ghost, thenAgatha could find in the Midnight Sons the perfect way to atone for her sins. The supernatural team is rumored to be coming to the MCU, and a dark squad that takes out threats like demons and vampires is perfect forAgatha Harknessto do some good.
