Zendaya's fashion choices during the promotional tour for Spider-Man: Brand New Day have sparked online speculation that her character, MJ, could face a tragic fate in the new Marvel film.

Fans on social media have pointed to the actor's mostly black outfits during the press tour, suggesting they may hint at a major storyline involving MJ. However, there has been no official confirmation from Marvel Studios or the filmmakers.

Zendaya and her longtime stylist, Law Roach, are well known for using fashion to reflect themes from the films they promote.

During the tour, Zendaya wore a blue-and-red outfit in Rome, colours closely linked to Spider-Man's costume. She also appeared in a grey-blue dress featuring web-inspired details.

For most of the remaining promotional events, however, she chose black outfits, a colour often associated with mourning in Western cultures. At an event in China, she wore a black Versace gown with black net detailing, even though white is traditionally considered the colour of mourning in China and several other Asian countries.

These fashion choices have led some fans to speculate that MJ may die in Spider-Man: Brand New Day.

The theory gained further attention after Zendaya said in a recent interview: "As a fan of Peter Parker, I always want him to have a happy ending, but I don't know, guys... it's not looking good."

Marvel actors are generally bound by strict non-disclosure agreements that prevent them from revealing plot details before a film's release.

Fans have shared various theories online, with some suggesting the outfits were carefully chosen to hint at MJ's storyline. Others believe they are simply part of Zendaya's signature fashion-forward promotional style.

For now, the speculation remains unconfirmed. Audiences will learn what happens to MJ when Spider-Man: Brand New Day opens in cinemas worldwide.
