Warning: This post contains potential spoilers for Avengers: Doomsday.
Marvel Studios revealed the first official trailer for Avengers: Doomsday during the Walt Disney Pictures presentation at CinemaCon 2026.
Marvel Boss president Kevin Feige said Avengers: Doomsday takes place after Avengers: Endgame, while also connecting back to the origins of the X-Men.
The trailer features the first look at Robert Downey Jr. as Doctor Doom. In one scene, Thor attempts to strike Doom with Stormbreaker, but Doom effortlessly stops it with his fingers.
Here’s the description of the Avengers: Doomsday trailer shown at CinemaCon:
We hear the words, “Something’s coming. Something we may not be able to deter,” over the ruins of the X-Mansion.
Doctor Doom is seen kneeling, with his face visibly scarred.
Thor says he has faced many enemies, but none as terrifying as this, warning that everything they sacrificed will mean nothing if they don’t stand together.
“I have fought many warriors in my time. They were far stronger than all of us put together—and they died. They died facing enemies and threats that scared me far less than this one.
Everything they sacrificed for will mean nothing if we do not stand together… If you return, you will return as brothers and sisters.”
The footage shows Thor approaching Doom with Stormbreaker, while the Fantastic Four meet the MCU heroes. Shang-Chi is seen fighting Gambit, and Mystique transforms into Yelena Belova.
Thor leaps at Doom with Stormbreaker, but Doom stops the attack instantly.
Steve Rogers then approaches Thor and says, “Hey, pal.” Thor replies, “It’s not possible.” Steve reaches for Mjolnir, which flies from Thor’s hand into his.
The trailer ends with the text: “12.18.26 is Doomsday.”
Here’s the new synopsis for Avengers: Doomsday from Walt Disney Studios:
“Beloved heroes from three distinct universes will be set on a deadly collision course and face an existential threat unlike anything they’ve ever encountered.”
