FACT CHECK
DigitEYE India decided to investigate this claim and found it to be false. The clip is not an official Marvel release or a genuine first look. It appears to be AI-generated and was created as fan-made content by an independent user.
We first conducted a reverse image search on various keyframes of the video to learn about the source. However, the search results displayed the same clips from several unverified sources over social media. Marvel has not released any trailer or confirmation on their Youtube channel. The latest video uploaded on Marvel’s channel is Robert Downey Jr.s entry to the Walt Disney Studios CinemaCon Presentation.
Next, we searched other accounts that have shared the same clip for additional information and context. Through a comment, we learned that this was created by user ‘samaidiector’ who shared this exact clip on 17 April, 2026. He admits that the clip is “a fight conceptual of Ai” and not a real event.
Upon searching for more information about Marvel’s official Doomsday trailer, we learnt that Marvel Studios debuted the Doomsday trailer exclusively during Disney’s presentation at CinemaCon 2026 in Las Vegas on April 16, 2026. According to Hollywood Reporter, the trailer reveals the first full look at Doctor Doom with the film positioned as a continuation since “Doomsday picks up where Avengers: Endgame left off.”
The footage closes on a dramatic surprise moment as Chris Evans appears, prompting Thor’s stunned reaction, “It’s not possible.” View a section from the report below –
This trailer was shared exclusively at the event and is not released to the public. The official Marvel website confirms Avengers: Doomsday (directed by the Russo brothers) releases on December 18, 2026, in theaters.
Lastly, we ran the clip attached in the claim through an AI detector to check its authenticity. The results proved it is AI generated, view them below –
Thus, the claim is false.
