MCU fans lucky enough to attend Disney’s CinemaCon 2026 presentation were rewarded, as Kevin Feige and friends debuted a brand new trailer for Avengers: Doomsday. Most notably, this trailer is the first to feature Robert Downey, Jr.’s Doctor Doom, along with a host of X-Men, Avengers, and Fantastic Four characters.
Marvel likely isn’t releasing the trailer online just yet, but IGN was in the room and we can break down the footage.
The trailer opens with a shot of the Xavier Institute sign. The narration (presumably Downey as Doom) says, “Something is coming, something we might not be able to deter. Before this day is done, we shall divest with an unthinkable decision.” Patrick Stewart’s Xavier sees a bright light in the sky. We see Doom in profile.
Then we see Avengers Tower, though looking very different from normal. We see the Fantastic Four meeting with the Avengers and Thunderbolts and Letitia Wright’s Shuri meeting with Tenoch Huerta’s Namor. James Marsden’s Cyclops walks into a room. Chris Hemsworth’s Thor says he’s fought with many allies who all died facing threats that scare him far less than this new one.
Simu Liu’s Shang-Chi fights Channing Tatum’s Gambit in the X-Mansion. The Wakandans meet with the FF. Rebecca Romijn’s Mystique transforms into Florence Pugh’s Yelena Belova. We see Joseph Quinn’s Johnny Storm holding Vanessa Kirby’s Sue and Namor flying. Paul Rudd’s Ant-Man kisses his daughter, Kathryn Newton’s Cassie, on the forehead (the first confirmation she’s in the film). Thor says, “Put aside your petty squabbles. Presume nothing except this – if you return, we will return as brothers and sisters.”
Thor leaps at Doom with Stormbreaker, but Doom blocks the weapon. Thor laments that they’ll need a miracle to defeat Doom. Just then – “Hey pal.” Thor says, “It’s not possible.” Chris Evans’ Steve Rogers appears and summons Mjolnir from Thor’s hand. He’s looking long-haired and scraggly, even more so than in Infinity War.
Again, it remains to be seen when Marvel Studios will release this trailer wide online. Fans might have to wait until The Mandalorian and Grogu hits theaters in late May. Fingers crossed the wait isn’t that long.
Recently, we learned that Doomsday has enetered post-production, while its sequel, Avengers: Secret Wars, is now in preproduction. Marsden also revealed he’s delighted to finally be wearing a comics-accurate Cyclops suit.
