Captain Marvel reportedly set for a major role in 'Avengers: Doomsday,' fans joke: "Is there going to be a musical number again?"

Rumor is growing, and it appears that Captain Marvel and Monica Rambeau could be at the forefront of Avengers: Doomsday, dealing with whatever cosmic shenanigans the MCU can provide. With their combined power level, they may be the key to battling Kang (or whoever else chooses to be the largest issue in the multiverse).

Viewers are particularly interested in whether or not their unsolved tension in The Marvels receives some resolution. Monica and Carol's dynamic continues to be one of the most interesting elements of the next chapter of Avengers.

Their combined powers can potentially make them an unbeatable cosmic power, but some conflicts can easily form new problems to be confronted along the way.

According to the scoop by The Cosmic Circus:

"[Captain Marvel is] currently studying how Kamala’s bangle aka the Kree Quantum Bands work, as well as studying the jump point systems to see how she is able to recreate the events from The Marvels that could allow her to bring back Monica from wherever she went. Problem is, if she does that, she’ll be dooming her universe to a terrible fate."

Fans are already bracing for potential disappointment, with some joking speculating that Avengers: Doomsday could turn into a full-blown musical number. Others have poked fun at the film’s potential critical reception, humorously suggesting that the Russo Brothers are gearing up for a "15% on Rotten Tomatoes" scenario.

A user (@MontreBible) joked:

"Is there going to be a musical number again?"

Imagine Dr. Doom might break into song just to stay relevant.

Another user (@jonmcbrine) added:

"It is truly doomed, then."

They said it in the title, can’t say they didn’t warn us.

One more user (@FortniteIndex) said:

"Another Russo 15% on RT is coming."

A user (@kagril_) went on to say:

"Why i think that all these characters will be killed by Doom in the first 15 minutes."

Just like the audience by minute 16.

A user (@gagaxlinkinpark) thinks that:

"Movie ruined."

A user (@tobias4rieper7) quipped:

"Have they learned nothing?"

Learning requires consequences, and the MCU is still making billions.

Captain Marvel's role in Avengers: Doomsday

This growth makes Captain Marvel a central character in the multiverse saga, perhaps tying her actions to the greater crisis that is happening in Avengers: Doomsday.

Her increasing understanding of the Kree Quantum Bands and jump point systems may make her a vital player in the Avengers' fight against Kang or other looming threats, ComicBook.com suggests.

Moreover, her ethical dilemma—choosing between saving Monica and potentially endangering her own universe—adds emotional weight to her character arc.

Brad Winderbaum, as cited by ComicBook.com, stated:

"I will tell you that she’s certainly a big part of the MCU to me. Ms. Marvel is a really important show to us, and without going into great detail, because I don’t want to spoil anything, she is top of mind. So it’s going to be exciting to see where she pops up next."

Monica Rambeau's Avengers: Doomsday role

Monica's energy-based powers make her potentially one of the strongest characters in the MCU, and her expertise in alternate realities could be an invaluable asset for the Avengers.

Since The Marvels left her stranded in a parallel universe, bringing her back might be the first step in triggering major multiversal consequences.

Her possible position as a "bridge" between worlds suggests she can very likely be the key to either stabilizing or destabilizing the multiversal crisis.

If rumors comparing her to Vision in Infinity War are true, she may possess something that villains are desperately seeking—whether it’s her knowledge, her abilities, or a direct connection to the multiverse.

Also, Monica's return to the main MCU timeline could also result in a poignant scene with Carol Danvers, further exploring their complex mentor-pupil relationship.

The Cosmic Circus added:

"From what I’ve been told, we can expect both of them to return and Monica Rambeau’s role will be a tad more important to the story for this upcoming film, comparable to the role of the Vision in Avengers: Infinity War."
