A leaked teaser from Avengers Doomsday has taken over social media, with fans claiming it is the most exciting preview Marvel has released in years. The short clip, believed to be the fourth teaser for the film, surfaced online late Monday and quickly spread across platforms before being taken down from several pages. Marvel Studios has not commented on the leak so far.
The teaser reportedly opens in Wakanda, showing a new Black Panther stepping into a tense battlefield setting. The character remains masked, but the imagery has convinced fans that the Black Panther mantle will continue to play a major role in the next Avengers chapter. The clip then shifts to a cosmic backdrop where four figures appear briefly, widely believed to be the Fantastic Four making their first real connection to the Avengers storyline.
Fans have been quick to react, calling the teaser dark, focused and emotionally charged. Several users on X described it as a return to form for Marvel, comparing the mood to Infinity War and Endgame. One comment that gained traction read, “This is the first time in a long while that an Avengers teaser actually felt dangerous.”
Industry watchers say Avengers Doomsday is shaping up as a crucial film for the studio after mixed reactions to recent releases. The inclusion of the Fantastic Four has been heavily rumoured, but the leaked visuals have raised expectations that the team will have a substantial role rather than a brief introduction. Wakanda’s presence also signals continuity with the emotional and political weight established in earlier films.
Marvel has a history of staying quiet when early footage leaks online, often choosing to let speculation run its course. With fan excitement clearly high, many expect an official teaser or announcement in the coming weeks. Until then, Avengers Doomsday remains at the centre of online discussion, with viewers hoping the final film lives up to the promise shown in the leaked clip.
