Wondering which MCU heroes could join Spider-Man in Brand New Day? Rumors point to surprising cameos, recruitment missions, and multiversal setups that could shape Marvel’s next crossover events. With speculation ranging from street-level allies to cosmic powerhouses, the film may lay critical groundwork for Doomsday and Secret Wars.
Here’s every MCU hero who could appear in Spider-Man: Brand New Day.
Every MCU hero who could appear in Spider-Man 4: Brand New Day
Daredevil
With The Punisher making the jump from television to MCU films, Daredevil could also return with another cameo like his appearance in Spider-Man: No Way Home. The two heroes already share history in the MCU. Their New York City setting provides several natural scenarios for a brief but impactful team-up.
Captain America
Sam Wilson’s Captain America might appear to recruit Spider-Man for the events leading into Doomsday. This would match Marvel’s strategy of weaving solo stories into larger crossover arcs. Such a scene could also establish Peter’s place in the new Avengers lineup following the events of No Way Home, where he ended up working alone and without allies who remember him.
Shang-Chi
Shang-Chi could take the recruiter role instead of Captain America. Director Destin Daniel Cretton’s previous work on Shang-Chi and the Legend of the Ten Rings increases the chances of a cameo by Simu Liu. The character’s mystical Ten Rings could also connect to the larger multiversal conflicts teased for Secret Wars. This link could give Spider-Man a clear reason to join forces with him.
Captain Marvel
Captain Marvel is another possible addition due to Brie Larson’s past collaborations with Destin Daniel Cretton. Her brief appearance in Shang-Chi’s post-credits scene set a precedent for crossing into other heroes’ stories beyond her usual cosmic missions.
Tobey Maguire and Andrew Garfield’s Spider-Men
Tobey Maguire and Andrew Garfield’s Spider-Man variants could return for smaller cameos to help set up Doomsday and Secret Wars. Their appearance in Spider-Man: No Way Home was a major MCU milestone, and even a brief return could serve to remind audiences of the multiversal stakes ahead.
Miles Morales
Although Kevin Feige has said Miles Morales will not appear until Phase 7, speculation suggests Brand New Day could introduce him as a younger supporting character. The casting of Liza Colón-Zayas, who some fans believe could play Rio Morales, has fueled theories that Miles’ mother may debut in the film. This could set the stage for his eventual live-action arrival in Spider-Man 5.
Spider-Man: Brand New Day is scheduled to release in theaters on July 31, 2026.
