Being a multiverse movie, no theory could be too absurd or wrong. Although it seems like it could be a wild theory,
Ultron Of Earth-838 Marries Wanda Maximoff Of His Universe
And that explains why Wanda Maximoff of Earth-616 never searched for her one true love in Earth-838. Wanda Maximoff of the Illuminati Universe met Ultron instead and she fell in love with him.
Sadly, Billy and Tommy were never real in WandaVision
The two children in WandaVision are creations of Wanda's reality-altering magic, as is the Vision in that series. As such the WandaVision are not real 'children' have no 'father'.
While Earth-616 Wanda presumably destroys herself along with Mount Wundagore and all knowledge of the Darkhold, Earth-838 Wanda is still alive with Billy and Tommy in their home universe.
Regardless, Wanda and the Vision married and operated as both Avengers and a duo while she explored her powers and origins.
While she could've physically given birth to the boys in this universe, it might also mean that Earth-838's Wanda peacefully created her children. Between Vision's nonexistence and the good Ultron bots in Earth-838, all signs point to Avengers: Age of Ultron not happening in Earth-838.
After her Earth-838 self tells her “Know that they'll be loved,” the Scarlet Witch says that no one will use the power of the Darkhold again. Making good on her word, she uses her chaos magic to collapse Mt. Wundagore - destroying all copies of the Darkhold across the multiverse and burying herself within Mt.
It takes another Wanda to truly understand the pain that she is in and the love she feels for her sons. After all the destruction the Scarlet Witch caused, Earth-838's Wanda ends her tirade with a single line; "Know that they'll be loved."
No Real Character Development
It is possible that 838's Wanda did not become an Avenger because Age of Ultron happened very differently. But even if she did, she retired pretty early and took on a suburban life with her kids.
Wanda 616, our Wanda, is much more powerful than Wanda 838. At the end of WandaVision, we see our Wanda become the Scarlet Witch, which means she has even more power, energy and potential.
Billy and Tommy's Father Is Reed Richards of Earth-838
The signs that Reed may be trying to protect Wanda because she's his wife are subtle but more evident when called out. For example, his main focus is to stop and potentially kill Dr. Strange rather than listen to his plea that the real threat is The Scarlet Witch.
Wanda Maximoff (Earth-838)
READ SCARLET WITCH AND VISION'S BLOCKBUSTER SERIES HERE! Long-time Avengers Wanda Maximoff, AKA Scarlet Witch, and the automaton Vision share a love story for the ages. But how did the all-powerful mystic and the synthetic man meet?
The good news is that Wanda and Vision's children weren't destroyed. Rather, their souls are reincarnated in new bodies to be raised by new surrogate parents. Once Billy and Tommy come to grips with their growing powers and their direct connection to the Avengers, their shared superhero destiny truly begins.
What is this? Interestingly, Richie Palmer's response to the question of a possible Magneto appearance in Doctor Strange in the Multiverse of Madness appears to confirm that the Wanda of Earth-838 is likely a mutant.
They reveal that the Strange they knew tried to use the Darkhold, and they had to kill him as the book had corrupted that Strange. Meanwhile, Wanda takes over the body of Wanda 838 and heads to the Illuminati, and brutally murders them all.
While looking strikingly similar to the main reality of the MCU, known as 616, Earth-838 had some major differences, including waterfalls flowing from skyscrapers, flora growing from rooftops, and a new superhero team in the form of the Illuminati, comprised of representatives from each superpowered team.
Doctor Strange's third eye appeared on his forehead involuntarily not long after using the Darkhold, which corrupts any being that uses it, regardless of how powerful or pure they are. It pulled Agatha Harkness and Scarlet Witch into villainy, and Doctor Strange grew a third eye despite limiting his exposure to it.
From time to time, the Eye can be seen as a manifestation on Strange's forehead which gives him special powers. Doctor Strange's third eye (the Eye of Agamotto) in the comics, according to Bustle, represents wisdom of the sorcerer Agamotto and his Vishanti.
This new information about Wanda's past also helps Agatha figure out the truth behind Wanda's powers, after which she calls her by the name long affiliated with her Marvel comic book counterpart — the Scarlet Witch. “I know what you are,” says Agatha.
Earth-838 is a reality alternate to Earth-199999. On Earth-838, the existence of Inhumans such as Black Bolt and the Terrigen Mist has been known for some time, though for how long and in what capacity Inhumans have contributed to this Earth's history is unknown.
Character information
She is an alternate version of Maria Rambeau from the prime Marvel Cinematic Universe, and originates from the Earth-838 universe. She is portrayed by Lashana Lynch. Captain Marvel was a member of the Illuminati, an organization compromised of the Earth's heroes.
On Earth-838, Wanda Maximoff lived with her sons Tommy and Billy in their house in Westview. In 2021, Maximoff was ambushed and had her body taken over by the prime timeline's Wanda Maximoff, who had dreamwalked into her.
It could very well be that his decision to leave was about not wanting to cross paths with Wanda until he'd done this, and once again discovered his worthiness. Even without reconciling his memories and emotions, he would've also regained enough insight to know how powerful Wanda is.
Olsen also revealed to Collider that the decision was made for her character to only seek out a universe where it was just her and her kids. Had Wanda's plan succeeded, she may have had to remove her variant to take her place as her sons' mother.
