10 Unannounced MCU Characters Teased in the Spider-Man: Brand New Day Trailer

The trailer for the new movie was released on May 18, 2026, and Marvel fans are thrilled! The 2-minute, 40-second preview confirmed fan theories and hinted at several characters who might appear in Spider-Man: Brand New Day, joining an already impressive cast.

Though not officially confirmed, the trailer for Spider-Man: Brand New Day strongly suggests appearances by characters like Sadie Sink as Jean Grey and Yelena Belova, who might be important to a new Mutant Task Force. Fans are eagerly awaiting the film to see if these hints turn out to be true, and the possibility is incredibly exciting.

Sadie Sink Is Likely Playing Jean Grey

When Marvel announced that Sadie Sink, known for her work on Stranger Things, would be in Spider-Man: Brand New Day, fans immediately began speculating about her character. The most popular guess is , but Marvel has been very secretive, and nothing official has been revealed.

After the release of the Spider-Man: Brand New Day trailer, most fans believe actress Sydney Sweeney will play a character with strong telepathic abilities. While the trailer doesn’t show her face, a scene suggests she can jump into people’s minds, and she’s wearing yellow and green – colors associated with the mutant Jean Grey. If this is correct, it means the introduction of mutants into the Marvel Cinematic Universe could happen sooner than expected.

William Metzger May Be the First Anti-Mutant Villain in the MCU

Okay, so a month back, Marvel let us know Tramell Tillman was joining the cast of the new Spider-Man: Brand New Day series. The trailer just dropped, and it’s official: he’s playing William “Bill” Metzger. And let me tell you, he’s not going to be one of Spider-Man’s buddies! He’s running the Department of Damage Control, which basically means he’s after anything Sadie Sink’s character throws at the world – looks like he might end up helping Spidey out of necessity, though.

The character will appear in the movie and is described as a hateful activist who uses media to promote their views. They lead a group called the Anti-Mutant Militia and publish a propaganda newspaper, “The Militia Press.” This casting strongly suggests that Sink will play a mutant, and the character could become the main force driving anti-mutant sentiment within the Marvel Cinematic Universe as the story of mutants begins.

Agent Ramirez Could Be Working with An Anti-Mutant Task Force

William Metzger is confirmed to be involved, and he likely won’t be the only familiar face in the upcoming Spider-Man: Brand New Day. A quick glimpse in the trailer at the 1:28 mark shows a Spider-Man lab scan done by someone named Agent Ramírez, and many fans believe actress Liza Colón-Zayas will be playing that part. She was cast some time ago, but her role has remained a secret until now.

While a few characters named Ramírez appear in Marvel comics, Delores Ramírez is the most likely to join the Marvel Cinematic Universe. She’s a CIA agent who works for the X-Desk, a government team focused on monitoring and controlling mutants. This supports the idea that Jean Grey will soon appear in the MCU, and everything suggests that the storyline from Spider-Man: Brand New Day will be the starting point for introducing mutants into the franchise.

Paul Rabin Comes From a Different Reality In Comics

Fans expected Spider-Man: Brand New Day to be sad because of Peter Parker and Mary Jane’s broken relationship, but the trailer revealed it’s even more painful. MJ has clearly started dating someone else – a man named Paul, played by Eman Esfandi. Now, Peter has to watch MJ find happiness with another man while he continues his life as the neighborhood’s friendly Spider-Man.

Many fans doubted Paul would appear in the Marvel Cinematic Universe, largely because of his complicated history with Peter and MJ in the comics. Now that his appearance is confirmed, viewers are curious about his role. Will it be a minor one, simply to appease fans, or will he be portrayed as his comic book counterpart from Earth-23321, further expanding the film’s multiverse elements? So far, the movie feels fairly realistic, so the extent of his multiversal connection remains a question.

The Punisher May Become the Beast of the Hand

A surprising element of the Spider-Man: Brand New Day trailer was the return of the Hand. This villainous group has been a comic book staple for decades, primarily challenging Daredevil and Elektra. However, Spider-Man, as a hero who often fights local battles, has also encountered them. Their appearance hints at a larger danger: the Beast of the Hand.

Fans believe the Hand, a mysterious group, is planning to corrupt another hero and transform them into a host for the Beast – an old demon that gives the group its powers. Many think this new host will be Daredevil, mirroring a storyline from the comics. This would create a dramatic showdown between Spider-Man and Daredevil, and expand the history and motivations of the Hand.

Ned Leeds Could Finally Become the Hobgoblin

It’s been nearly a decade since Ned Leeds first appeared in the Marvel Cinematic Universe, and fans are still hoping he’ll become the villain Hobgoblin, just as he did in the comics. The upcoming film, potentially Spider-Man: Brand New Day, might finally make that happen. The trailer reveals Ned has changed his look, sporting a new hairstyle and glasses.

These small details might seem insignificant, but they hint at a major development to come. It’s possible Ned will become an enemy Peter has to confront, which would make the movie even more heartbreaking. Peter would not only lose his friend, but as Spider-Man, he’d be forced to battle him to protect others.

Elektra Works for The Hand and Could Return in a Big Way

When a mysterious hand appeared in the trailer for Spider-Man: Brand New Day, fans online started speculating about what it meant. One popular theory involves the Punisher transforming into the Hand’s Beast, but another focuses on a specific heroine. This character, sometimes called the Daughter of the Hand, has a complex history with the organization, as they essentially trained her to work for them.

Ever since the Daredevil: Born Again series, fans have been curious about what happened to Elodie Yung’s character, Elektra. The Netflix show left her fate uncertain, leading many to believe she survived and is planning a return. Given that this version of Elektra was already connected to the Hand, it would be a natural fit for her to appear as a supporting villain in Spider-Man: Brand New Day.

Yelena Belova May Mentor Peter

A rumor started in August 2025 suggesting Florence Pugh, who plays Yelena Belova (a New Avenger), will appear in Spider-Man: Brand New Day. Although Yelena isn’t shown in the movie’s trailer, fans believe there’s a connection between Spider-Man: Brand New Day and the film Thunderbolts based on a subtle clue.

Fans have pointed out a similarity between the fog seen during Spider-Man’s swings and the one that covered New York during the Void’s attack. This has led many to speculate that it foreshadows the arrival of Yelena Belova, possibly through a flashback showing what happened to Spider-Man during that dangerous event.

Daredevil & Spider-Man Share a Lot

The trailer for Spider-Man: Brand New Day doesn’t show Matt Murdock (Daredevil), but the villainous group The Hand—previously seen in the Netflix Marvel shows—is present. If The Hand is involved, Matt will likely want to help fight them, particularly if they’ve taken control of the Punisher. Many fans are hoping to see a classic Daredevil and Spider-Man team-up as a result.

With major players like The Hand, the Beast, and Elektra Natchios appearing, it makes sense for Daredevil to join the Spider-Man: Brand New Day storyline. Daredevil has been a guardian of New York City for over ten years, and it’s surprising he and Spider-Man haven’t crossed paths yet. The recent meeting between Peter and Matt suggests Spider-Man: Brand New Day could finally address this long-standing oversight in the Marvel Cinematic Universe.

Kingpin Is One of Spidey’s Best Villains

In the trailer for Spider-Man: Brand New Day, at the 36-second point, Spider-Man receives the keys to the city from Sheila Rivera. Rivera, played by Zabriyna Guevara, is a key member of Wilson Fisk’s mayoral campaign team. This connection between the character and Fisk has fans hoping to see a showdown between Spider-Man and the Kingpin in the new film.

As a huge comic book and movie fan, I’ve always loved the dynamic between Daredevil, Spider-Man, and Kingpin. While Kingpin’s been a major villain in the comics for both heroes, the Marvel Cinematic Universe has, so far, kept him limited to the TV shows—a result of the Disney/Sony arrangement. But there’s a lot of buzz that could change, and I’m really hoping we see him in Spider-Man: Brand New Day. Considering the story is set in New York City, and Kingpin is the mayor, it honestly feels like leaving him out would be a disservice to the narrative!
