Just a day after the apparent leak of Marvel’s first Avengers: Doomsday trailer, a look at Spider-Man: Brand New Day also appears to have been spilled online, offering a big clue to Sadie Sink’s mystery character.
The leaked Spider-Man trailer is of extremely low quality, but — like Avengers — is now being scrubbed from the internet by copyright claims, effectively confirming its legitimacy. According to one report, the video originated from a market research app which offers early peeks at marketing materials to gauge audience feedback.
While much of the trailer is hard to make out visually, its audio is easier to understand. The biggest reveal? That Sadie Sink’s character is clearly threatening Peter Parker — and knows his secret identity as Spider-Man.
Sink’s role in Spider-Man: Brand New Day has been kept firmly under wraps by Sony since her casting was announced, while a recent on-set sighting showed the Stranger Things star bundled up in an apparent bid to hide her costume.
Fan speculation on who Sink might be playing has been rife, with everyone from the X-Men’s Jean Grey to Mayday Parker up for grabs. But a persistant rumor has pointed to Sink playing shapeshifting multiversal villain Shathra — something that fans are now leaning towards after hearing her character speak.
“You’re a mess, Spider-Man,” Sink’s character says. “Don’t get in my way. Otherwise, it won’t just be your friends who don’t remember who Peter Parker is.”

While the trailer begins with Peter Parker telling someone he is Spider-Man (it’s hard to make out who), it’s unclear how Sink’s character knows Peter’s secret the whole world was made to forget. And there’s clearly no love lost between the two — at least from this dialogue.
But could this all be a double bluff? Sony and Marvel’s Spider-Man movies have a habit of surprising audiences with characters’ true identities (MJ and Mysterio, to name two). And with Sink reportedly returning for 2027’s climactic Avengers: Secret Wars, has she really just been cast as this film’s villain?
“A lot of people forget that hair color can change, but, yeah, I understand all of the theories,” Sink said recently, when asked about all the redheaded Marvel characters that fans have speculated she’s playing. “Tom [Holland] can wave at the fans because people know who he is, but then you get a glimpse of me and I’m [wrapped up] like a penguin. That’ll be the situation for a bit, it seems.”

Other notable lines in the trailer include Spider-Man talking to “Professor Banner,” and the arrival of Frank Castle, AKA Punisher, who tells Peter he’s here to “save your ass.” Marvel has been coy around Mark Ruffalo’s involvement in the movie, though at this point it is an open secret. As for Frank, played once again by Jon Bernthal, it’s just nice to see him after years in Marvel’s Netflix-era shows.
It’s been a remarkable week for Marvel, which is still expected to officially release its first look at Avengers: Doomsday alongside Avatar: Fire and Ash. Reportedly, four different trailers will launch over the next four weeks to encourage repeat viewings of Avatar, each focusing on a different character. With this all in mind, it seems likely we weren’t supposed to see a first look at Spider-Man still for some time.
