Warning: This post contains spoilers for Avengers: Doomsday.
Marvel Studios has another Avengers: Doomsday surprise for the San Diego Comic-Con attendees this year on the Marvel Hall H panel. The first was amazing, isn’t it? But you got more on the second. But, the new trailer won’t be released online, it’s only for the attendees.
According to insider James Mack, who claimed to have watched the leaked version of the trailer, he has shared the new Avengers: Doomsday trailer description. Here’s the details:
The castle is shown from the inside, highlighting several environments and details. Doom walks through the corridors until he reaches a huge painting of a woman and a child (just like the poster), while a voice in the background says, “My family was killed because of you.“

Cut to the Fantastic Four’s ship arriving on Earth. Thor flies to the ship, then it cuts to the same scene of Steve picking up Mjolnir. Then, Thor, the Fantastic Four, and Steve arrive at Avengers Tower, shown from a new angle.
Steve greets Sam and Bucky. Reed says they have less than 24 hours to stop the incursions. Steve talks to Yelena.
Two ships depart with two different groups. Some heroes are inside one of them, and Doom can be seen behind them.
Scenes in Talokan. Yelena fights another Mystique disguised as Yelena.
Nightcrawler vs. Reed. Shang-Chi vs. Gambit. Cyclops shoots at Sam. Beast and Reed talk. Magneto appears in his suit in a place I couldn’t identify.
Then, a scene at the Fantastic Four Tower. The X-Men are present, and Gambit looks at Mjolnir on a table.
Reed and Doom talk. Loki appears at Steve’s house.
A scene shows a bloody hand in a TVA hallway. The same Doom vs. Thor scene.
The video ends with the Avengers, the X-Men, and Reed facing Sentinels and Doom. It’s the same scene that leaked previously, but much more complete and visually better.
The Avengers: Doomsday logo appears.
In the last shot, Doom stares at Steve. The screen goes black, and Doom’s voice can be heard saying, “You will forgive me one day.”
Here’s the official new plot synopsis for Avengers: Doomsday:
