WARNING: MAJOR SPIDER-MAN: BRAND NEW DAY SPOILERS AHEAD. DON’T READ IF YOU HAVEN’T WATCHED THE MOVIE YET.
How Does Spider-Man: Brand New Day End?
Spider-Man: Brand New Day finally reveals its biggest mystery: the role of Sadie Sink. True to the longstanding theories, the Stranger Things star plays the X-Men's Jean Grey, officially bringing one of Marvel's most powerful mutants into the MCU.
While Jean initially appears to be the film's villain, with Spider-Man (Tom Holland) helping Damage Control capture her, he ultimately realizes that isn't the case after learning Sara, the sister she’s looking for, has been subjected to strange psychic experiments by Damage Control and was killed.
Overcome with grief, Jean freezes thousands of people across New York. Spider-Man arrives and assures her that she isn't alone, sharing his cherished memory of Aunt May (Marisa Tomei) in an attempt to reach her.
However, the Punisher has already taken position on a nearby rooftop, preparing to shoot Jean. Peter's Spider-Sense warns him just in time, and he throws himself in front of the bullet, taking the shot to save her.
The Punisher rushes Spider-Man to the hospital while Jean uses her psychic powers to keep him alive long enough for him to receive medical treatment. Later, the web-slinger escapes the hospital and returns to his normal life.
As the movie ends, the traditional post-credits scene delivers what may be one of Marvel's most mysterious teases yet.
Ned's Spider-Man tracker app appears on screen, showing the beloved hero in New York before his signal gradually moves farther and farther away, eventually reaching outer space. So, what does this mean?
How Does Spider-Man: Brand New Day Connect to Avengers: Doomsday?
Spider-Man: Brand New Day's end-credits scene appears to tease either Avengers: Doomsday or Avengers: Secret Wars.
Based on what is shown, the mysterious outer space location revealed by Ned's tracker app could be Battleworld, the patchwork planet Doctor Doom created after stealing the god-like powers of the cosmic Beyonders in Marvel's 2015 Secret Wars comic.
While this seemingly points toward Secret Wars, it could also depict a distant planet beyond the solar system where Spider-Man ultimately ends up in Doomsday.
So far, it remains unclear whether Tom Holland will appear in Doomsday. However, Kevin Feige previously teased that more cast members would be announced beyond those already revealed, making Spider-Man's inclusion a real possibility.
Based on the film itself, Brand New Day largely stands on its own, with no major teases for Doomsday outside of its cryptic post-credits scene.
Instead, the introduction of Jean Grey to the MCU suggests that Marvel Studios is already laying the groundwork for the upcoming Mutant Saga.
