Sadie Sink’s Rumored Spider-Man 4 Character Code Name Sparks Intense MCU Fan Theories
According to Nexus Point News Editor-in-Chief Koc, “Hearing Annabelle Adams is the code name(?) for Sadie Sink’s character in Spider-Man: Brand New Day.” While this is far from confirmation, the report lines up with Hollywood’s long tradition of using misleading names during filming to throw off fans and the press, especially in big movie names like Spider-Man 4: Brand New Day.

Big-budget productions, especially within the MCU, often operate under strict secrecy. Code names protect plot twists, cameos, and even entire character arcs from being spoiled before release. That said, “Annabelle Adams” is not a random alias plucked out of thin air; she is, in fact, a character from Marvel Comics.
Created by Christopher Yost and Ryan Stegman, Annabelle Adams has ties to the Spider-Man universe through her relationship with Kaine Parker, also known as Scarlet Spider, a clone of Peter Parker. Their romance ended abruptly when Kaine transformed into a monstrous spider, prompting Annabelle to flee in fear.
Whether the MCU intends to adapt that storyline or simply borrow the name for misdirection is unclear. Still, the possibility of introducing Scarlet Spider into live-action has fueled passionate debate among Marvel enthusiasts.
Star-studded Cast Lineup Adds Even More Intrigue to the Sequel
Directed by Shang-Chi filmmaker Destin Daniel Cretton, Spider-Man 4 is bringing back familiar faces while adding new layers of star power. Tom Holland returns as Peter Parker, alongside Zendaya as MJ, Jacob Batalon as Ned Leeds, and Jon Bernthal reprising his gritty role as Frank Castle/The Punisher. Other confirmed cast members include Mark Ruffalo as Bruce Banner/Hulk, Michael Mando as Mac Gargan/Scorpion, and The Bear star Liza Colón-Zayas in an undisclosed role.
With Sadie Sink joining this already stacked lineup, Marvel has yet another opportunity to weave a new, possibly multi-film arc into the MCU’s broader narrative. If “Annabelle Adams” does hint at a Scarlet Spider connection, it could signal a darker, more complex storyline for Peter Parker’s next chapter, one that blends grounded emotional stakes with the kind of multiverse-driven surprises Marvel fans have come to expect.
Marvel’s Spider-Man 4: Brand New Day is slated for release on July 31, 2026, leaving plenty of time for rumors, theories, and speculative casting deep-dives to dominate fan discussions. Until the studio makes an official announcement, the question remains: Is “Annabelle Adams” a genuine clue to Sadie Sink’s MCU debut, or just another expertly placed Marvel misdirect?
