The MCU’s Most Ambitious Crossover Before Avengers: Doomsday Comes Out In 3 Months

The upcoming movie Avengers: Doomsday is expected to be Marvel’s biggest crossover event yet. Before it arrives, Marvel is releasing its most ambitious film so far in just three months. Doomsday will include a massive lineup of popular heroes, from Thor and Shang-Chi to the Fantastic Four. While not officially confirmed, rumors suggest characters like Ms. Marvel will also appear.

The upcoming movie, Avengers: Doomsday, is bringing together the core Marvel Cinematic Universe heroes and adding some familiar faces from the X-Men films. Actors like Patrick Stewart and James Marsden are returning as Charles Xavier and Cyclops, respectively. Surprisingly, Chris Evans is back as Steve Rogers, even after his character’s story concluded in Avengers: Endgame. And in a major twist, Robert Downey Jr. will be playing the villain Doctor Doom instead of his iconic role as Tony Stark.

With the cast now announced, it’s clear that Avengers: Doomsday is set to be the biggest team-up movie in the Marvel Cinematic Universe so far. But before it hits theaters on December 18th, Spider-Man: Brand New Day might briefly take the title of most ambitious team-up. While the movie mainly follows Tom Holland’s Spider-Man and won’t have as many characters as Doomsday, it could bring together different Marvel heroes and storylines even sooner.

Spider-Man: Brand New Day Could Unite The Avengers, Defenders, & X-Men

As a huge Spider-Man fan, I’m really excited about the potential crossovers in the new Brand New Day movie! The trailers have already shown us the Punisher and the Hulk, and it’s clear they’re not just cameos. It feels like Marvel is cleverly connecting different corners of their universe – the Hulk’s appearance hints at a link to the Avengers, and the Punisher feels like a way to bring in the more grounded, street-level heroes we loved on Netflix, like Daredevil, Jessica Jones, and the Defenders. It’s a smart way to build a bigger, more connected world!

The team-up of Hulk and the Punisher already made Spider-Man: Brand New Day a large-scale crossover, and No Way Home further expanded that with characters like Doctor Strange and Daredevil. However, the addition of Sadie Sink could really make Brand New Day stand out. While Sink is confirmed to be in the film, her role remains a mystery, sparking a lot of fan theories. The most popular theory suggests a potentially game-changing opportunity for the movie.

A lot of Marvel fans are hoping Sadie Sink will be cast as Jean Grey in the upcoming Spider-Man: Brand New Day movie. Jean Grey is a powerful psychic and a key member of the X-Men, a character previously known for being played by Famke Janssen and Sophie Turner in the X-Men films made by Fox. If Sink gets the role, Spider-Man: Brand New Day would be the first Marvel Cinematic Universe film to feature characters from the Avengers, the Defenders, and the X-Men.

We’ve seen X-Men characters like Wolverine pop up in the Marvel Cinematic Universe, most recently in Deadpool & Wolverine, but those appearances haven’t included the core Avengers or Defenders. While Spider-Man: Brand New Day might not have as many heroes as Avengers: Doomsday, if Sadie Sink is cast as Jean Grey, it could be the first film to bring together characters from the three biggest Marvel franchises – X-Men, Avengers, and Defenders – all in one place.

Spider-Man: Brand New Day Could Show How The MCU Will Handle The X-Men

If Sadie Sink is cast as Jean Grey, the upcoming Spider-Man: Brand New Day could give us an early idea of how Marvel will integrate the X-Men into the larger Marvel Cinematic Universe, well before Avengers: Doomsday arrives. Marvel has already experimented with mutant characters, altering the origins of Scarlet Witch and Quicksilver in Avengers: Age of Ultron. Plus, recent projects like Doctor Strange in the Multiverse of Madness and Deadpool & Wolverine have introduced alternate versions of characters like Professor X and Wolverine from different universes.

The recent Spider-Man: Brand New Day storyline might show us how the Marvel Cinematic Universe will integrate mutants into its stories. The way Jean Grey has reappeared suggests that the MCU has its own established group of mutants, and that the actors who played the X-Men at Fox might be from a different universe entirely. Alternatively, this Jean Grey could simply be a visitor from another universe within the larger multiverse, now entering the main MCU.

The upcoming movie will be a real test of whether Marvel can do these characters justice. While Fox’s X-Men films were inconsistent, and even Marvel has had varying success with its character adaptations, it’s still uncertain if characters like Jean Grey will live up to expectations when they join the MCU. The film Spider-Man: Brand New Day has the opportunity to show that the franchise is capable of handling these iconic heroes, even before Avengers: Doomsday arrives.
