Every Marvel movie and show has tons of surprises. One big surprise is always the appearances of other Marvel characters. Infinity War had the return of Red Skull. The mid-credit scene in Shang-Chi had Captain Marvel and Bruce Banner. Spider-Man: No Way Home had Daredevil and both Toby Maguire and Andrew Garfield’s Spider-Man. With Quantumania coming out in a few days, I figured why not take a guess who could show up in the movie. It has been said that Quantumania is meant to be an avengers type movie similar to Captain America: Civil War. With a statement like that, one would think some MCU alums would pop up even if its just for a scene.

Nick Fury (Samuel L. Jackson)

Samuel L. Jackson said in an interview awhile back that he had filmed three marvel projects at once because they were all filming next to each other. Two of those projects are Secret Invasion and The Marvels. It has been rumored that the third movie is Ant-Man and the Wasp: Quantumania mostly due to the fact that the movie was filming around the same time as the other two projects. It would be nice to see more Nick Fury. He pops up everywhere so it is possible he could factor in, in some capacity whether a credit scene or an appearance at the end of the movie. At most it could at least give an update where he is right now.

Likelihood of showing up: The best shot out of everyone solely based on the fact this had filmed at the same time as Secret Invasion and The Marvels.

Kate Bishop (Hailee Steinfeld)

Kate Bishop was introduced in Hawkeye and quickly became a fan favorite. There has been speculation that she would be in this movie. Realistically I am not sure how she could fit in unless there is a scene where Cassie meets Kate in a coffee shop or on the street.

Likelihood of showing up: Slim to none.

Hawkeye (Jeremy Renner)

If Kate Bishop were to appear and if it was a simple thing that she was in town and runs into Cassie therefore meeting for the first time, it is possible Kate could be in town with Clint Barton, a.k.a. Hawkeye. Also, Clint and Scott worked together before so there is an established relationship. Clint could be in town just to check up on Scott or to say hello.

Likelihood of showing up: Slim to none.

Shang-Chi (Simu Liu)

There has been speculation that there is a connection with the weapons used by the Ten Rings and Quantumania. The mid credit scene of Shang-Chi revealed that the rings are unlike anything that has been seen before and is probably thousands of years old. It was also revealed that Shang-Chi’s ring appeared to have sent out a signal. There has been fan speculation that the credit scene is happening around the same time as when Cassie sends out a signal to the Quantum realm based off the trailers. If the rings are connected to Kang, it would make sense if we see the scene again in a different context or see what happens after that scene once Kang is freed. At the very least the movie could end with Scott looking for Shang-Chi after learning more about the Quantum realm and wanting to see the ring for himself.

Likelihood of showing up: Decent shot.

Wong (Benedict Wong)

Wong was the unofficial MVP of Phase 4 showing up in multiple projects. Given Wong was also involved in Shang-Chi as well as the midcredit scene, it would also make sense if Wong popped up here in relation to that. Also, if Shang-Chi makes an appearance and if it is the same scene from a different context, it would make sense for Wong to be there as well. Even if Shang-Chi doesn’t appear, Wong could still show up anyway, especially since he is the Sorcerer Supreme.

Likelihood of showing up: 50/50.

Doctor Strange (Benedict Cumberbatch)

At this point, even if we have not gotten specific scenes with them, all of the heroes who fought Thanos have met. They all attended Tony Stark’s funeral so realistically they probably interacted with each other there. Even if Doctor Strange doesn’t have any scenes with the group, it is possible for him to show up in an isolated scene or interact with Kang. At the very least we could get a credit scene to give an update to where Doctor Strange is now after the events of Multiverse of Madness. Also, Kang probably knows everything anyway. Even if Doctor Strange is in a different world Kang would probably know about it and be able to find him easily. On a side note, if Doctor Strange does appear in the movie, it would help better link Multiverse of Madness to the bigger picture.

Likelihood of showing up: Decently but I wouldn’t hold my breath.

Madisynn (Patty Guggenheim)

Madisynn was introduced in She-Hulk, and she was hilarious throughout that episode. She also developed a friendship with Wong. Madisynn wound up in multiple dimensions including possibly one where she met Mephisto in the episode she was in. Even as a gag I could see Madisynn randomly show up in the Quantum realm where she goes on about how she got there to begin with.

Likelihood of showing up: Slim to none but anything is possible.  

Deadpool (Ryan Reynolds)

Deadpool will finally be joining the MCU in 2024 when Deadpool 3 comes out. Realistically Deadpool will probably not be in this. However, there could be a scene to set up how Deadpool winds up in the MCU to begin with. It also would be a nice tease to get fans hyped for Deadpool 3.

Likelihood of showing up: Slim to none.

Loki (Tom Hiddleston)

Given the events of Loki, it would make sense if Loki himself shows up. If Quantumania references the events of the Loki season finale, it would be the perfect opportunity to see Loki. The season finale also ended with Loki being stuck in another world where Kang is the ruler. Season 2 of Loki is due to come out later this year. The movie could set up season 2. There could be a scene where Kang meets Loki. Even it does not happen in Quantumania, there is a good chance Kang will show up in season 2 of Loki.

Likelihood of showing up: 50/50.

Sylvie (Sophia Di Martino)

Sylvie was introduced in Loki. Since she is the one who killed He Who Remains and caused this whole multiversal mess it would make sense if she were to appear.

Likelihood of showing up: 50/50.

Mobius (Owen Wilson)

Since Loki seems to have profound repercussions for the events of the Multiverse Saga, it seems fitting that the bulk of the cast could show up in Quantumania. Mobius works for the TVA which stands for The Time Variance Authority. The TVA regulates all realities and timelines. They course correct anything that should not be in the timeline which was the basis for Loki’s show since he broke off from the original timeline, he was supposed to be in.

Likelihood of showing up: Better shot than some of the others.

Ravonna Renslayer (Gugu Mbatha-Raw)

Same reasons for the other three. In the comics Ravonna Renslayer has a long history with Kang including being his lover. Because of this, there has been speculation that she is connected to Kang. If the MCU goes this route, it would make sense if she were to show up in this. She could still show up even if they are not going to go this route. She was last seen in the season finale of Loki looking for answers. Her journey could lead her to the Quantum realm and to Kang.  

Likelihood of showing up: Maybe.

Miss Minutes (Tara Strong)

Out of all of the Loki cast, Miss Minutes seems like the one who could realistically show up other than Loki. After Tara Strong posted a tweet saying “It’s time y’all” in response to Ant-Man & the Wasp: Quantumania, fans have been speculating if that meant that Miss Minutes will be in the movie. It could also mean that Tara Strong is just excited to see the movie.  

Likelihood of showing up: 50/50.

Dr. Erik Selvig (Stellan Skarsgard)

We have not seen much of Dr. Selvig these last few years. He did return briefly in Thor: Love and Thunder. That scene was a video call with Jane. Dr. Selvig could factor in simply by studying the Quantum realm in a lab or in his office.

Likelihood of showing up: Not impossible but not very likely.

Sam Wilson (Anthony Mackie)

Since this is the third Ant-Man movie, it would be full circle if Sam popped up. Sam made an appearance in the first Ant-Man movie. He could be in a scene at the beginning of the movie. It could be simply Sam and Scott having lunch together.

Likelihood of showing up: 50/50.
