The post-credits scene in the VisionQuest finale features Robert Downey Jr.’s Doctor Doom reviving Wanda Maximoff, which appears to set the stage for her return in Avengers: Doomsday.
The season finale, titled “Forever,” aired on Disney+ on 10 November 2026, concluding a trilogy of Marvel series that began with WandaVision in 2021. While the episode focused on the reunion of Vision with his sons, Tommy and Billy, the mid-credits sequence revealed that Robert Downey Jr.’s Doctor Doom is reviving Wanda Maximoff in the ruins of Mount Wundagore, according to BBN Times.
Terry Matalas discusses the Maximoff family reunion
Showrunner Terry Matalas addressed the decision to bring the Maximoff family back together in the finale. Although the series featured the return of Billy Maximoff, played by Joe Locke, and Tommy Shepherd, played by Ruaridh Mollica, Wanda Maximoff did not appear in the main episodes of the season.
For @THR, I spoke with #VisionQuest creator @TerryMatalas about telling an MCU story about fathers & sons, why he decided to have Vision & Tommy reunite with Billy but NOT Wanda, that ominous mid-credits scene with Ultron — and remembering @SirPatStew: https://t.co/tOcVHRuaVc
Matalas explained to TheWrap that the creative team had constant discussions regarding Wanda’s involvement.
“Listen, the Wanda conversation was constant, and if we felt strong enough about it, we would have done it,” Matalas said.
The reunion between the twins and their father, Vision, served as a central emotional beat. Joe Locke, who portrays Billy, told the Los Angeles Times that the moment felt momentous.
Matalas also clarified the timing of Billy’s appearance. While the creators considered introducing the character earlier, Matalas told TV Guide that they feared it would have detracted from the specific story being told between Vision and Tommy.

“We had conversations about 'Do we bring him in earlier?' or not, but every time we went down that road, it sort of would detract from the story of Vision and Tommy that we were on.”,” Matalas said.
Ultron and Vision face a final conflict
The finale pitted Vision, played by Paul Bettany, against Ultron, played by James Spader. Rather than a traditional battle, the conflict was resolved through conversation.

In the episode, Vision and Ultron initially engage in a physical fight, with Ultron gaining the advantage because he can transform into a cloud of nanomachines. Vision then traps their minds within the “UltraVision” sitcom.
During this confrontation, Ultron—who was restored to his robotic form for the first time in the series—regresses to a dangerous and pessimistic state following the death of Jo. Ultron stated, “They want extinction,” regarding humanity.
The confrontation was driven by the loss of Jocasta, an A.I. character.
Emotion is what tips the genocidal android over the edge, Spader said, as reported by Marvel.com.
As Ultron appeared broken and sad, he conceded defeat and destroyed the drones, which resulted in the death of both himself and Vision. However, Billy Maximoff, who had previously been reborn in the body of William Kaplan in the series Agatha All Along, appeared to help Tommy resuscitate Vision in the real world.
Matalas noted to TheWrap that the decision to include this specific post-credits scene was made by him and the writers rather than Marvel.
Scarlet Witch returns for Avengers: Doomsday
The resurrection of Wanda Maximoff via Doctor Doom provides a direct link to the next phase of the Marvel Cinematic Universe. The scene implies that the Scarlet Witch will be involved in the events of Avengers: Doomsday, which is scheduled to hit theaters on 18 December 2026.
The post-credits scene, which was not included in press screeners, shows Robert Downey Jr.’s Doctor Doom reviving Wanda in the ruins of Mount Wundagore. During the revival, Doom declares that her powers will belong to him. Some fans have theorized that she may become one of his Latverian Witches, appearing alongside a witch in purple and a witch in green.
While Marvel Studios has not officially confirmed the specific role Elizabeth Olsen will play, Comic Book Resources reports that the end-credits tag suggests she may appear as an ally to Doctor Doom.
The upcoming film is directed by Anthony Russo and Joe Russo, and features Robert Downey Jr. as the villain Doctor Doom, according to Comic Book Resources. Other confirmed cast members for the film include Pedro Pascal as Reed Richards / Mr. Fantastic and Vanessa Kirby as Sue Storm / Invisible Woman.
“All those answers are above my pay grade,” Matalas said regarding the future of the characters, as quoted by TV Guide.
