Something's coming...
Days before San Diego Comic-Con 2026, Marvel Studios has released the first trailer for Avengers: Doomsday, the highly-anticipated Marvel Cinematic Universe (MCU) film directed by Anthony and Joe Russo that will finally unite Marvel superteams the Avengers, the Fantastic Four, and the X-Men.
The two-minute, twenty-second trailer opens with the unsettling image of a charred Xavier's School for Gifted Youngsters sign as we hear a voiceover from Doctor Doom (Robert Downey Jr.) who warns in a thick Latverian accent, "Something's coming..."
We see Professor X (Patrick Stewart) being blinded by a flashing glare, possibly from a universal incursion, as Doom's voiceover continues, "...Something we may not be able to deter. Before this day is done, we shall be faced with an unthinkable decision."
We shift to an overhead shot of Manhattan as we see the renovated Avengers Tower. Inside, Thor (Chris Hemsworth) is giving a speech as we see him and the Fantastic Four enter. "I've fought with many warriors in my time," he begins as we see Sam Wilson as the second Captain America, the Winter Soldier, and Ant-Man. "They were far stronger than all of us put together..."
The camera pulls back to reveal the former Thunderbolts, now known as the New Avengers, are there as well. "...and they died," Thor says omniously. "They died facing enemies and threats that scared me far less than this one..."
We get a montage of fleeting images including Namor and Shuri as the new Black Panther as Talokan soldiers surround King M'Baku and his men. This is followed by Cyclops firing an optic blast and what looks to be an impressive fight between Shang-Chi and Gambit.
As we see the return of Loki (Tom Hiddleston), who is holding a Time Variance Authority (TVA) identification card, Thor continues his speech with "Everything that they sacrificed will be for nothing if we do not stand together." This is followed by the Thing shaking M'Baku's hand as he's accompanied the Invisible Woman, the Winter Soldier, and Joaquin Torres as the second Falcon.
"Put aside your petty squabbles..." Thor continues as we see Yelena Belova (Florence Pugh) aiming her weapon at Mystique, who shapeshifts into a copy of Yelena, leading to a Yelena vs. Yelena fight. This is followed by a sad reunion of Professor X and Magneto. "...and presume nothing except this -- If you return, you will return as brothers and sisters." A montage of fleeting action images follows, ending with with Thor bringing Stormbreaker down on Doctor Doom, who blocks the weapon with two fingers.
"But mark my words, we're going to need a miracle," Thor concludes as Steve Rogers (Chris Evans) steps into view. "Hey, pal," says Steve.
"It's not possible," replies Thor as we holds up his original hammer, Mjolnir. Saying nothing, Steve holds up his right hand and Mjolnir flies from Thor's hand to Steve's. Thor is stunned by this, while Steve simply looks down at Mjolnir and gives a small smile.
The trailer ends with the return of the Avengers theme music, followed by a countdown clock to Doomsday.
