Marvel fans finally have an answer to one of the MCU's biggest mysteries, and the timing could have major consequences for Avengers: Doomsday (2026).
For years, viewers have wondered whether a powerful Avenger actually died during her last appearance. Marvel left the character's fate unresolved, allowing speculation about a possible comeback to continue.
Now, a Disney+ finale has revealed that the character is alive. Unfortunately for Earth's Mightiest Heroes, the circumstances surrounding her return suggest she could become a dangerous enemy.
The surprise also involves Doctor Doom, whose plans could become considerably more threatening if he gains control of her extraordinary abilities.
Disney+ Finale Reveals a Familiar Marvel Character
Marvel's VisionQuest (2026) recently completed its eight-episode run, continuing the story of Vision (Paul Bettany) following the events of WandaVision (2021).
The series explores Vision's complicated existence after S.W.O.R.D. reconstructed his body following his destruction in Avengers: Infinity War (2018).
His return created difficult questions about his identity, memories, and relationship with Wanda Maximoff (Elizabeth Olsen).
However, Wanda's own fate remained uncertain.
In Doctor Strange in the Multiverse of Madness (2022), Scarlet Witch seemingly sacrificed herself after realizing the damage she had caused while desperately trying to reunite with her children.
She destroyed Mount Wundagore, bringing the structure crashing down around her.
Although the scene suggested Wanda had died, Marvel never showed her body. That omission kept hopes of her survival alive.
The VisionQuest finale has now addressed that mystery.
Doctor Doom Awakens Scarlet Witch
The revelation arrives after the finale's main story concludes.
During a post-credits scene, a mysterious hooded figure approaches the rubble left behind by Mount Wundagore's destruction.
As the figure approaches, enormous rocks begin lifting from the wreckage. Beneath them lies Wanda Maximoff, completely motionless.
The mysterious visitor turns out to be Doctor Doom.
Rather than simply discovering Scarlet Witch, Doom appears interested in using her powers for himself.
“Scarlet Witch. Awaken. Your power shall be mine,” he declares.
The camera focuses on Wanda's face as she remains still beneath the rubble.
Suddenly, her eyes open, and she gasps for air.
The moment establishes that Scarlet Witch survived the events of Doctor Strange in the Multiverse of Madness (2022).
However, Doom's involvement raises another troubling possibility: Wanda might return as an enemy rather than an ally.
Wanda Could Become a Dangerous Threat to the Avengers
Scarlet Witch has already demonstrated how destructive her abilities can become.
During Doctor Strange in the Multiverse of Madness (2022), she attacked anyone standing between her and the children she hoped to reclaim.
Her grief and desperation pushed her toward increasingly dangerous decisions, transforming a former Avenger into a formidable opponent.
Although Wanda eventually recognized the consequences of her actions, her history creates an opportunity for Doctor Doom.
He could manipulate her emotions or exploit her desire to regain what she lost.
Speculation about Wanda joining Avengers: Doomsday (2026) has circulated for months, particularly after images showing Doom alongside mysterious witches appeared online.
Her confirmed MCU return now gives those theories additional momentum, although her participation in the upcoming film remains uncertain.
If Doom manages to control Scarlet Witch, the Avengers could face an opponent capable of manipulating reality itself.

Could Scarlet Witch Eventually Turn Against Doom?
Of course, Wanda's return doesn't necessarily mean she will remain a villain.
One theory suggests Doom could initially convince her to attack the Avengers before she discovers his true intentions.
That discovery could push Wanda toward another redemption story.
After all, she previously recognized her mistakes at Mount Wundagore, even after causing enormous destruction.
Her powers could also make her a valuable ally against Doom if she eventually rejects his influence.
Beyond the upcoming crossover, Elizabeth Olsen could potentially return in future mutant-focused Marvel projects.
Scarlet Witch's connections to the X-Men in Marvel Comics leave several storytelling possibilities available.
For now, those outcomes remain speculation.
Marvel Prepares for Its Next Avengers Crossover
Avengers: Doomsday (2026) will bring several major Marvel characters together when it arrives on December 18.
Robert Downey Jr. will portray Doctor Doom, while Chris Evans returns as Steve Rogers and Chris Hemsworth reprises his role as Thor.
Characters connected to the Fantastic Four, X-Men, and Avengers will also appear.
Whether Wanda joins that conflict remains unclear, but her survival creates another major possibility for Marvel's future.
And with Doctor Doom already showing interest in Scarlet Witch's powers, her return might bring considerably more trouble than the Avengers expect.
