Marvel's Multiverse Saga races toward its close with two massive Avengers films. Fresh whispers now point to a familiar face rejoining the fray in spectral form.
Insider Alex Perez shared the detail in a Cosmic Circus Q&A. Kathryn Hahn might reprise Agatha Harkness as a companion character in Avengers: Secret Wars. The role would build directly on her ghostly presence alongside Billy Maximoff from the WandaVision spin-off Agatha All Along.
Perez confirmed Billy's strong presence in the film. He also backed a Champions project that ties into Marvel's Young Avengers plans. Avengers: Secret Wars follows Avengers: Doomsday, set for December 18, 2026.
Hahn first played the centuries-old witch in WandaVision. She stole scenes as the nosy neighbor Agnes before revealing her true power-hungry self. The 2024 Disney+ series Agatha All Along gave her the lead. There she formed a coven, walked the Witches' Road, and sacrificed herself to save Billy. She returned as a ghost to guide him in the search for his twin Tommy.
That ending left the door open. Hahn has voiced interest in more. At D23, she said she would love to return if asked. Earlier comments suggested she had not heard about the big Avengers movies at the time. Rumors of this sort often stay fluid until cameras roll. Perez noted filming for Secret Wars approaches soon.
The companion angle fits the larger setup. Billy Maximoff, played by Joe Locke, stands poised for a bigger stage. Young heroes have gathered slowly across Disney+ shows and films. Concept art leaks and prior teases already pointed that way. A Champions series or film would give them their own spotlight after the event movies. Perez said the project is coming. VisionQuest should offer more clues when it arrives.
Fans have largely cheered the possibility. Some still puzzle over Agatha's family history and lingering threads from the series. One light jab imagined ghost Agatha constantly pestering Billy ahead of big battles. The tone stays playful more than critical. Hahn's dry delivery and comic timing made Agatha a standout. Pairing her spectral version with the next generation keeps that energy alive without forcing a full resurrection.
The Russo brothers direct both upcoming Avengers entries. They have balanced sprawling casts before. Secret Wars draws from the comic event of the same name plus elements of Children's Crusade. That storyline already mixed Wanda Maximoff's family with young heroes. Magic, runes, and hexes from the earlier shows may play key roles. Agatha's knowledge of those systems could prove useful amid Doctor Doom's schemes.
Production timelines remain tight. Doomsday hits theaters first. Secret Wars lands the following December. Any confirmed casting will surface closer to cameras rolling. Marvel has kept many details under wraps, as usual. Hahn's prior Emmy-nominated work and the series' solid reception give the rumor real weight among followers.
What comes next depends on how the Multiverse Saga resolves. A Champions project would expand the younger roster. Billy shining in Secret Wars could lock in that path. Agatha as ghostly advisor offers a low-stakes way to keep Hahn in the mix. It also honors the character's comic history of mentoring from beyond.
The buzz stays light for now. Official word will settle it once filming ramps up. Until then, the rumor gives fans one more reason to rewatch the Westview stories and track every Maximoff clue.
