Marvel Theory: X-Men Movies Are Part Of The MCU Multiverse

Marvel Studios could make the X-Men movies part of the MCU's multiverse through Fox's Quicksilver actor, Evan Peters, who has reportedly been cast in WandaVision. Peters played Marvel's mutant speedster and the son of Magneto in X-Men: Days of Future Past, X-Men: Apocalypse, and the final film in the main series, X-Men: Dark Phoenix.

The initial casting of Evan Peters as Quicksilver came at an interesting time, as X-Men: Days of Future Past was in development right when Marvel was working on the sequel to The Avengers. The plan for Avengers: Age of Ultron was to introduce three more members of Earth's Mightiest Heroes: Scarlet Witch, Quicksilver, and Vision, with Aaron Taylor-Johnson was cast in the role of Quicksilver. Since Quicksilver and Scarlet Witch were two of a small number of characters whose rights were shared by Marvel and Fox, it was possible for each studio to have their own version of Pietro Maximoff. Both studios using the same character at the same time brought a lot of interest to the actors' portrayals of the character, and comparisons between the two were unavoidable.

Avengers: Age of Ultron killed off Quicksilver but kept Scarlet Witch (Elizabeth Olsen), whereas the X-Men franchise continued to reuse Quicksilver, but avoided his sister. Quicksilver fans were understandably disappointed that the classic Avenger was abandoned by the Marvel Cinematic Universe, and despite numerous rumors of his return, Quicksilver has remained dead in the MCU. Time travel and alternate realities being added as new concepts for the MCU to play with has fueled speculation that Aaron Taylor-Johnson's Quicksilver could make a comeback, but it's possible that the X-Men version will be utilized in his place. Before, it was never possible before for any X-Men character to be used in any way in the MCU, but with their rights restored to Marvel, Marvel can not only use Cyclops and Wolverine, but now they can go a step further and make the X-Men MCU canon. Here's how that could work.

WandaVision May Deal With Alternate Realities

Marvel hinted at the existence of alternate realities when Doctor Strange (Benedict Cumberbatch) mentioned the number of possible outcomes of the battle with Thanos (Josh Brolin) in Avengers: Infinity War. The concept was firmly established in Avengers: Endgame when the Avengers created an alternate reality by tampering with the timestream. Based on its title, Doctor Strange in the Multiverse of Madness will presumably go there again by creating a story that involves the Sorcerer Supreme and Scarlet Witch exploring other dimensions. Due to the deep connection between the Phase 4 MCU movies and Disney+ shows, WandaVision is expected to set up Scarlet Witch's Doctor Strange 2 role. That would mean that WandaVision too could touch on various parallel universes.

Parallel universes could be what was shown in footage for WandaVision, which contained glimpses of several different versions of Scarlet Witch and Vision (Paul Bettany). It looks like WandaVision will reimagine the couple in several different scenarios, with each one being reminiscent of a sitcom from a particular era. It appears that what's happening here is that Wanda is using her reality-warping abilities from the comics, but it could be that Wanda has instead found herself in the multiverse, living out all the versions of what her life could have been.

How Marvel Can Use Fox's Quicksilver In WandaVision

Marvel Studios head Kevin Feige has teased that the MCU's Scarlet Witch will become more like the hero from the comics, and this has led some to believe that when she begins to develop the powers of her comic book counterpart, she'll begin to rewrite reality and cause all sorts of havoc. Fans have theorized that Scarlet Witch will use her new abilities to resurrect Quicksilver, but it could be that Marvel does indeed want to use Pietro - just not the version of the character that everyone is expecting. Instead, Marvel could bring in Evan Peters' take on Quicksilver, who was admittedly more popular than the MCU interpretation.

While visiting alternate realities in the multiverse, Scarlet Witch could go looking for her brother, and discover that in one world, her brother is a totally different person. In the X-Men movies, his name is "Peter", not "Pietro". His backstory and personality differs from the MCU hero as well. That being said, he still has his super speed and his most distinguishing physical characteristic, which is his silver hair. A meeting between Wanda and Peter would draw parallels to what the Arrowverse did with "Crisis on Infinite Earths" when it allowed its version of the Flash (Grant Gustin) to meet the DCEU's Scarlet Speedster, played by Ezra Miller. It became one of the most talked-about moments that ever occurred in the Arrowverse, and a scene in WandaVision with Fox's Quicksilver would have a similar reaction.

As for how important he could be, it could just be a single scene, but the report that Evan Peters is playing a "key role" suggests that he'll have a significant amount of screen time for at least one episode. It could be that he'll even share an adventure with Scarlet Witch and Vision.

What Fox's Quicksilver In WandaVision Would Mean For The MCU

Evan Peters appearing in WandaVision as Quicksilver - even if it was just a blink-and-you-missed-it cameo - would mean that the events and characters featured in the X-Men movies share their own corner of the MCU's multiverse. This scenario with Peters isn't too different from what some are thinking could happen with Sam Raimi's Spider-Man trilogy in Doctor Strange 2. Such a move would expand the scope of the MCU in a big way and allow for some fun cameos, but that doesn't mean that this is how Marvel will bring the X-Men into the MCU. Now that Marvel and Disney finally has the rights to the characters, they'll of course still seek to create their own versions of Marvel's Merry Mutants. Marvel won't rely on Fox's, unless they have one or two specific characters they'd like to use.

While Hugh Jackman's Wolverine would be high on everyone's radar and would make for an excellent cameo in a future Marvel project, Evan Peters' Quicksilver is perhaps an even better choice. Marvel's treatment of Quicksilver hasn't been well-received, considering that he was killed off in his first movie (despite being a major Avengers character). Many feel that the MCU needs a Quicksilver, and if Aaron Taylor-Johnson's character is off the table, a good solution to this problem is to bring in a version of the character who audiences liked even more.
