WandaVision has been big on mystery since the very beginning, and the internet has been hot with theories on what is going on. Those theories have really exploded as of late, though, after actress Elizabeth Olsen teased a cameo appearance by a Marvel character so big, it compares to Luke Skywalker's reveal in Season 2 of The Mandalorian.
Luke appearing in The Mandalorian was such a big reveal that it seemed all but impossible before it actually happened. Going off Elizabeth Olsen's promise and a bit of logic of who would make sense, I constructed a list of potential names of who could appear in WandaVision. Some make sense, while others are just worthy of a major reveal, but I can guarantee would be absolutely awesome if they happened.
Magneto
It would be insane to see the father of Wanda Maximoff appear, especially since, for licensing purposes in the past, the MCU has skirted around the topic of Wanda and Pietro's father. Now that Disney owns the X-Men, it could be completely fine to reveal Magneto as Wanda's father (even if Marvel Comics has retconned it), minus the fact that mutants have not been officially introduced to the MCU. Then there's also the question of who would play Magneto, given Ian McKellen would be too old to be Wanda's father, and Michael Fassbender too young. Recasting the role would be easy enough if you threw someone in the costume, though, and it would be a pretty cool casting reveal for it to happen in WandaVision.
Tony Stark
I mean, if we're going to talk about major Luke Skywalker-scale cameos, this is about as big as it gets. Robert Downey Jr. shooting a surprise scene for WandaVision would be huge, though one I would ultimately assume would be a one-and-done appearance. Disney paid a small fortune for the actor at the end, and bringing Tony back after he sacrificed his life in Avengers: Endgame would be a huge hit to the film's relevance. If Tony is in WandaVision, would have to be either as some hallucination, conjuration, or even an in-joke in an advertisement that would be fantastic. Truthfully, I want this to happen far more than I believe it will happen, but don't we all deserve to dream?
Quicksilver (Aaron Taylor-Johnson)
It's fair to speculate at this stage that Wanda has brought Vision back to life in her sitcom world, so could she do the same with Pietro Maximoff? Aaron Taylor-Johnson hasn't been in the MCU since the character's death in Avengers: Age of Ultron, so his return would be considered a big deal in any capacity. I think that given the fact he was mentioned in Episode 3 of WandaVision, it's certainly not crazy to believe that Wanda could accidentally create him in her universe or have some weird hallucination in which she sees him. I wouldn't expect Quicksilver to be in witness protection given his death, but wouldn't that be a wild twist if he actually survived and went undercover in the United States with the FBI's help?
Quicksilver (Evan Peters)
There's another weird theory floating around the web that Quicksilver will appear in WandaVision, just not the one Wanda Maximoff knows. Evan Peters, who portrayed Quicksilver (Peter Maximoff) for Fox's X-Men films before the Disney acquisition, was a popular character that Marvel might try to find a home for. Perhaps if those mutants existed in a different multiverse, and Wanda is involved in a movie dealing with the multiverse, she could accidentally summon Quicksilver from another dimension? Under that theory, he couldn't be a missing person, so maybe this is just wishful thinking on my end.
Doctor Strange
I think if you talk to many people staying on top of the lore and clues of WandaVision, Doctor Strange is the most obvious pick for the reveal. This series is supposed to lead into the events of Doctor Strange in the Multiverse of Madness, so it only makes sense that the title character would have some cameo in the series at some point. If this were the case, he might be someone who helps bring Wanda back to reality or a cameo in the season finale that puts us right up into Doctor Strange 2.
Ant-Man
When it comes to characters I most associate with Jimmy Woo, Scott Lang is high up on the list. This is because of their relationship in Ant-Man and the Wasp, and that Jimmy would be on the lookout for Scott if he did turn up missing following Avengers: Endgame. Really the thing that excites me most about this possibility is how WandaVision could recreate Scott's shrinking or giant abilities with classic sitcom effects. Plus, if someone could lay low in Westview without Wanda being aware, it seems like he would have the best chance of hiding in such a small place.
Hawkeye
Clint Barton may not be the most exciting choice for a cameo, but he does have a show on the way on Disney+. Beyond that, he also is a friend of Wanda Maximoff, who would likely want to check on her well-being in the weeks after her return to see how she's been coping with Vision's death. My thought is that Clint is somewhere in Westview, and possibly the missing person that Jimmy Woo alluded to in Episode 4. After all, what kind of missing person would be considered light work for a SWORD agent like Monica Rambeau, but still important enough for her to aid the FBI in tracking down? Then again, I'm not sure Clint Barton going in "witness protection" is possible given that he doesn't wear a mask, so that's a part of the mystery I can't really figure out.
Thanos
It sounds crazy to speculate that WandaVision would feature the villain who ultimately perished in Avengers: Endgame, but in a show that focuses on Wanda's trauma, I think it wouldn't be crazy for her to conjure her Vision's murderer as an unwelcome guest in her little reality. Plus, if we're talking a major cameo, I think Josh Brolin reprising a role we all assumed he was absolutely finished with as a one-and-done cameo is pretty big. I also think it would be hilarious to see Thanos appearing in a random sitcom format but proceed to act perfectly normal. I'm not sure how likely this one is to actually happen, but I can say I want it a lot.
WandaVision airs on Disney+ Fridays. Any picks on this list you like more than the other? List your favorite or share another option in the comments, and let's cross our fingers the reveal is awesome.
