A new trailer for Spider-Man: Brand New Day has been released, and it gives fans an exclusive look at Hulk in the movie, along with a brief look at Sadie Sink’s mystery character.
The trailer starts with Tom Holland’s Spider-Man worried about changes happening to him that he can’t control. During a fight with Scorpion (Michael Mando), he loses his temper. In another scene, Peter Parker is feeling sad and alone while watching videos of MJ and Ned online. Because of what happened in Spider-Man: No Way Home, they no longer remember who he is.
Peter then discovers that he’s naturally shooting webs from his wrists. In a state of panic, he goes to Bruce Banner for help. Peter asks about controlling mutations, and Banner explains that he uses a device to help keep the Hulk under control.

The trailer also teases a mysterious villain. Someone describes them as “a threat we can’t control and can’t even see.” We briefly see Sadie Sink’s unknown character. Many fans think she might be Jean Grey, but nothing has been confirmed.
A strange wave then freezes people all over New York. Spider-Man seems to be the only person unaffected, likely because of his Spider-Sense. The villain appears to be able to take control of other people’s minds and switch between them.
Later, Peter talks with MJ and Ned. MJ is dating someone else. The villain possesses a random person and threatens MJ right in front of Spider-Man.
Spider-Man confronts the villain, but things get worse when Bruce Banner’s control device breaks and the Hulk appears. It seems possible that the villain may have controlled Banner and caused the transformation.
The Hulk then appears to target MJ, so Spider-Man tries to protect her. He asks her to trust him, and she agrees. They escape together and eventually seek help from The Punisher.

The trailer also shows Spider-Man fighting The Hand, a group of evil ninjas, while using what looks like a stronger new form. Near the end, Peter hears encouraging words from Aunt May.
