MCU Rumor Reveals Sadie Sink’s Secret Villain Role for Phase 6

by

Rumors are swirling about Sadie Sink’s mysterious role in the upcoming Marvel film, Spider-Man: Brand New Day. While it’s been known since mid-March that the Stranger Things actress, age 23, is joining the cast, her character remains a secret. Fans have speculated she might play Mary Jane Watson, Mayday Parker, Jean Gray, or Gwen Stacy, but Marvel hasn’t confirmed anything yet.

A recent rumor suggests Sadie Sink might be the main villain in *Spider-Man 4*, finally giving fans a possible idea of her role in the upcoming Marvel movie.

On the latest episode of *The Hot Mic* podcast, insider John Rocha revealed some new information about the main villain in *Brand New Day*. He told co-host Jeff Sneider that sources suggest Sneider was correct in his previous speculation: the villain is a female shapeshifter.

I’ve got some exciting news about the show! People close to the production, and even someone who attended a recent Disney presentation about Spider-Man: Brand New Day, have told me the main villain will be a female character with shapeshifting abilities. They’ve already cast the actress, but I can’t reveal her name yet. It’s unclear if she’s playing the Chameleon or a different shapeshifter.

He didn’t reveal the identity of the shapeshifter, only that the actor playing the role had a name he wasn’t sharing.

Rocha confirmed that characters like Tombstone and Scorpion appear in the movie, but they aren’t the primary antagonists.

Tombstone and Scorpion appear in the movie, but they aren’t the primary villains. A source overseas (though this is unconfirmed) suggests Boomerang will also be included. Additionally, MJ has a new boyfriend, which upsets Peter and contributes to a darker, more realistic tone for the film.

I was so excited when Marvel insider Cryptic HD Quality shared his ideas about what role I think Sink could have in the next Phase 6 movie!

An insider shared a clue on X, responding to a fan with a text bubble taken from a Spider-Man comic. The bubble read, “You’ve probably noticed over the past year, more and more of your battles have been coming from the supernatural side of the street.”

This information comes from *The Amazing Spider-Man* #506, an issue that heavily featured the villain Shathra. These recent reports suggest that actor Jake Gyllenhaal might be playing Shathra as the new antagonist in the *Brand New Day* storyline.

This fits with information Rocha received from his sources and hints from Cryptic’s recent online post, strongly suggesting who Sink might be portraying in the upcoming movie.

The latest Spider-Man movie, Spider-Man: Brand New Day, will be released in theaters on July 31, 2026. This new film marks a fresh start for Tom Holland’s Peter Parker, who is trying to live a normal, private life after the intense events of Spider-Man: No Way Home.

I’m really excited to see the cast coming together for this movie! Tom Holland will be working with Hunter Schafer, and they’ll be joined by some fantastic actors like Michael Mando, Mark Ruffalo, Jon Bernthal, and Zendaya. It’s shaping up to be an incredible group!

Who Is Shathra in Marvel Comics?

Shathra is a Spider-Man villain who hasn’t gotten much attention, but she’s appeared in the comics several times over the past 70 years.

Shathra comes from our universe (Earth-001) and was given a special mission by her divine parents: to create a map charting the destiny of humankind. But when her parents choose her sister’s design for a map of the entire Multiverse instead, Shathra becomes consumed by a desire for revenge.

Driven to create a Multiverse that surpasses her sister’s, she journeys between realities, charting the presence of humanity throughout different dimensions. During her travels, she encounters Peter Parker, also known as Spider-Man, and believes his abilities would be the ideal nourishment for the creatures she’s cultivating across the Multiverse.

This creates conflict between the two characters, as Spider-Man fights to hold off Shathra while also defending New York City from its regular criminals.

Shathra can shapeshift, travel between universes, and fly. When she’s not appearing as a human, she also has sharp claws and a dangerous stinger.

There have been teases of Multiversal elements being present in Brand New Day‘s primarily grounded story, so Shathra’s inclusion could make sense, bringing some otherworldly seasoning to sprinkle on top of a mostly street-level Spider-Man tale.
