Marvel Studios is building toward one of the biggest superhero movies ever made, Avengers: Secret Wars. The film is expected to be the ultimate crossover event for the Marvel Cinematic Universe, bringing together heroes, villains, and alternate versions of characters from across the multiverse.
Ever since Marvel introduced the multiverse in projects like Doctor Strange in the Multiverse of Madness and the Disney+ series Loki, fans have been wondering which characters might appear in the final battle.
Reports from industry insiders suggest that Secret Wars may follow a similar structure to Avengers: Infinity War. The movie could introduce a huge group of heroes and villains before focusing on a smaller “dream team” that leads the fight to save reality.
Because the story involves multiple universes colliding, Marvel has the opportunity to bring back characters from older Marvel movies, introduce brand-new heroes, and even show dark variants of familiar characters.
Here are 10 Marvel characters who could appear in Avengers: Secret Wars that fans might not expect.
Avengers: Secret Wars – 10 Marvel Characters Who Could Surprise Fans
1. Molecule Man
One of the most important characters from the original Secret Wars storyline is Molecule Man.
In Marvel Comics, Molecule Man can control matter at the molecular level. This means he can literally reshape reality itself. Because of this incredible power, he becomes a key figure in the Secret Wars storyline.
In some comic versions of the story, Molecule Man acts as the energy source that holds together a new world called Battleworld, where different realities collide.
Interestingly, some fan theories suggest that the MCU might adapt this idea differently. After the ending of Loki Season 2, many viewers believe Loki could take on a similar role by holding the multiverse together.
If Marvel introduces Molecule Man, he could easily become one of the most powerful characters in the entire MCU.
2. The Beyonder
Another powerful cosmic figure who could appear is Beyonder.
In the original Secret Wars comics, the Beyonder is a mysterious being with god-like powers. He creates Battleworld and brings heroes and villains from across the universe to fight each other.
The Beyonder isn’t just powerful; he is curious about human emotions and conflict. That curiosity is what leads him to create the massive battle between Marvel heroes and villains.
If Marvel Studios follows the comics closely, the Beyonder could be the real mastermind behind the events of Secret Wars, possibly manipulating characters like Doctor Doom from behind the scenes.
Introducing a cosmic character like the Beyonder would raise the stakes of the MCU to an entirely new level.
3. Ghost Rider (Nicolas Cage)
Fans have been waiting for Ghost Rider to return to live-action movies for years.
One rumor suggests that Nicolas Cage might return as his version of the character from the older Ghost Rider movie.
Because Secret Wars will likely feature the multiverse, Marvel has the perfect opportunity to bring back characters from older Marvel movies.
Ghost Rider would also add something unique to the Avengers lineup. His supernatural powers, flaming skull, and dark personality would bring a completely different energy than that of traditional heroes.
4. Blade (Wesley Snipes)
Another legacy character who could appear is Blade, played by Wesley Snipes.
Snipes starred in the original Blade, which many fans consider one of the movies that helped start the modern superhero film era.
Marvel is already working on a new Blade movie for the MCU, but bringing back Wesley Snipes for a cameo in Secret Wars would be a powerful moment of nostalgia for longtime fans.
It would also be a great way to celebrate Marvel’s history before the MCU even existed.
5. Tobey Maguire’s Spider-Man
One of the most emotional moments in the MCU happened when Tobey Maguire returned as Spider-Man in Spider-Man: No Way Home.
Fans loved seeing three different Spider-Men fighting together in the same movie.
Because Secret Wars is expected to be even bigger, there is a strong chance that Maguire’s Spider-Man could return once again.
Many fans believe the movie could feature a massive Spider-Verse style battle, where multiple Spider-heroes from different universes fight side by side.
6. Daredevil (Ben Affleck Variant)
Another surprising rumor suggests Ben Affleck could return as Daredevil.
Affleck originally played the character in Daredevil, long before the MCU began.
Today, the MCU already has its own version of Daredevil, played by Charlie Cox. But the multiverse allows Marvel to show different versions of the same character.
A quick cameo from Affleck’s Daredevil would be a fun surprise for fans who remember the early 2000s Marvel movies.
7. Rachel Summers
Reports suggest Sadie Sink may be joining the MCU.
One possibility is that she could play Rachel Summers, the powerful daughter of Cyclops and Jean Grey.
Rachel is a powerful mutant who possesses telepathic and telekinetic abilities similar to her mother.
Introducing Rachel Summers could help Marvel start building the next generation of X-Men characters in the MCU.
8. Captain Hydra
The multiverse allows Marvel to explore darker versions of familiar heroes.
One rumored character is Captain Hydra, an evil version of Captain America.
In this storyline, Captain America secretly works for the villainous Hydra organization.
Some rumors suggest Chris Evans could return to play this darker variant. Seeing a villain version of Captain America would be shocking for audiences.
9. Ultron
Another villain who could return is Ultron, voiced by James Spader.
Ultron was originally defeated in Avengers: Age of Ultron, but because he is an artificial intelligence, it’s always possible that another version of him survived somewhere in the multiverse.
A smarter and more dangerous version of Ultron could easily return as part of a villain team.
10. Wolverine
Finally, one of the most exciting rumors involves Wolverine, played by Hugh Jackman.
Jackman is already returning as Wolverine in Deadpool & Wolverine, which officially connects Fox’s X-Men universe with the MCU.
If Wolverine appears in Secret Wars, fans could finally see him fighting alongside the Avengers, something many viewers have wanted for years.

Final Thoughts
If even a few of these rumors are true, Avengers: Secret Wars could become the biggest Marvel movie ever made.
The film has the potential to bring together characters from multiple Marvel eras, including older movies, the MCU, and new heroes from upcoming stories.
From legendary characters like Wolverine and Ghost Rider to surprising appearances from legacy actors, Secret Wars may celebrate decades of Marvel storytelling in one epic battle.
Of course, most of these appearances are still rumors, theories, and fan speculation, and Marvel Studios has not officially confirmed many of them yet. But that uncertainty is exactly what makes the upcoming film so exciting.
