In Avengers: Secret Wars (2025), the final teaser trailer gives fans a jaw-dropping glimpse into the massive scale of Marvel’s multiverse war. Picking up from the events of Avengers: The Kang Dynasty, the multiverse is on the brink of collapse. The trailer opens with an ominous voiceover from Doctor Strange, warning of the chaos unfolding across countless realities. We see flashes of collapsing timelines, where cities and worlds blur together, creating a chaotic and apocalyptic landscape.
The teaser quickly ramps up, showing our heroes scattered across different dimensions, each fighting their own battles. Captain America (Sam Wilson), Thor, and Spider-Man (Tom Holland) are seen trying to regroup after the devastating loss of their teammates. Meanwhile, Iron Man’s legacy seems to live on through a mysterious new character seen donning upgraded Stark technology. There’s also a fleeting glimpse of a villainous Kang the Conqueror (Jonathan Majors), orchestrating the destruction of entire universes from his hidden throne, looking more menacing and powerful than ever.
As the trailer progresses, fan-favorite characters from across the multiverse begin to appear. Wolverine (rumored to be Hugh Jackman), a variant of Black Panther, and even the return of Deadpool (Ryan Reynolds) are all seen joining the fight. There’s also a brief but exciting introduction to the Fantastic Four and the X-Men, as they prepare to face off in a multiversal war with reality itself at stake.
In a shocking turn, Doctor Doom is revealed as a central figure in the chaos. He has been manipulating the multiversal collapse, seeking to reshape existence in his own image. The final moments of the trailer show a confrontation between Doom and Kang, both vying for control over the ultimate power—the Beyonder, a cosmic being hinted at in previous Marvel films.
The trailer concludes with an epic shot of all the heroes, from different realities, charging toward an unseen enemy in a shattered, apocalyptic landscape, setting the stage for the most ambitious battle ever seen in the Marvel Cinematic Universe.
