After Avengers: Infinity War, this is the first that we’ll see of Vision ever since he was killed by Thanos. Well, first he was killed by Wanda herself in order to protect the stone from Thanos, but Thanos then reversed time and killed Vision to procure the stone for himself, then completing all the empty spaces in his Infinity Gauntlet. He then proceeded to wipe out half of the life in all of the universe to restore balance. WandaVision will focus heavily on alternate time reality, and Wanda Maximoff, a.k.a., Scarlet Witch, played by Elizabeth Olson will finally get the spotlight she deserves and the MCU fans will not see her power. The buzz for the series is building even after the release of the first two episodes, and it should come as no surprise that the MCU has some more tricks up its sleeve that hasn’t been leaked yet. Outside of Vision (Paul Bettany) and Wanda Maximoff, aka Scarlet Witch (Elizabeth Olsen), much of the show’s cast has already been revealed. Kathryn Hahn is playing Agnes, the nosy neighbor Teyonah Parris is playing a grown-up Monica Rambeau, and Kat Dennings and Randall Park are reprising their roles as Darcy Lewis and FBI Agent Jimmy Woo, respectively.
Besides the titular characters, there have not been any other major players of Marvel introduced in WandaVision (as of yet). The series has the chance to bring classic Marvel characters to the front of the audience’s minds, including both well-known and obscure heroes and villains from Marvel Comics that may change the MCU as we know it.
Harkness is a fellow sorceress and she is much older than either of our protagonists, meaning she has been witness to many of the major events in Marvel Comics history. Kathryn Hahn’s character seems as though she knows more than she’s letting on, which could suggest that she is portraying a modern version of the one and only Agatha Harkness. If it comes to be revealed that Agnes is, in fact, the MCU’s answer to Harkness, then it would seem fitting for this series to follow a House of M style storyline – the Maximoff/Vision children had better keep one eye open… or they could look to another relative for help.
We have already seen Pietro Maximoff on our screens in the MCU, with an underwhelmingly short role in Avengers: Age of Ultron. As this reality-bending series is speculated to be Wanda’s own creation, there would be nothing stopping her from bringing her brother back to join the residents of Westview. As most Marvel fans would know, the X-Men have had their own adventures in their own separate universe, including a much more successful run for their very own Pietro Maximoff. In this canon, Quicksilver is still alive and is a prominent member of the supergroup. Disney’s acquisition of Fox in 2019 opens a lot of doors for potential appearances from X-Men stars in the MCU, with Kevin Feige already teasing the arrival of mutants in the future.
We will see none other than our favorite character, the Sorcerer Supreme, Doctor Stephen Strange. his involves Maximoff losing her mind after her children are taken away from her, which then causes her to create her own, ‘perfect’ reality. This, in turn, begins to create problems in the main reality (Earth-616) that the Avengers and the X-Men have to deal with. It would make sense for Strange to make a brief cameo appearance in this series, as it would help connect the first Disney+ series to the wider MCU and begin to build hype for the second solo outing for the Master of the Mystic Arts.
Mephisto is one of the most powerful enemies of the Marvel heroes in the comics; he is essentially the Marvel Universe’s answer to the Devil. Known for his ability to manipulate reality at will, Mephisto has faced off with many of the major heroes in the Marvel universe. His pocket universe is literally called Hell, which was his way of tormenting human souls. Mephisto unknowingly – when he inevitably claimed them back, he essentially killed her twin sons. Wanda’s memory of this was wiped by her mentor Agatha Harkness, but years later, Maximoff remembers and creates her own reality. If Mephisto appears in any capacity during this series, it would cement him as a figure in the MCU and allow the potential for him to feature in later projects.
Wonder Man, a.k.a Simon Williams, was originally a villain, deadset on destroying the Avengers after being manipulated by Baron Zemo. However, after a change of heart, Williams seemingly loses his life in saving ‘Earth’s Mightiest Heroes’ – this leads to Tony Stark keeping Williams’ brainwaves stored, later using them to create Vision. However, after a change of heart, Williams seemingly loses his life in saving ‘Earth’s Mightiest Heroes’ – this leads to Tony Stark keeping Williams’ brainwaves stored, later using them to create Vision. Believe it or not, we may have already seen our first tease for Wonder Man’s appearance in WandaVision already. In the opening credits of Episode 2, as Vision phases through the floor, we can see a glimpse of the helmet belonging to Grim Reaper; Wonder Man’s brother.
