The makers of Avengers: Doomsday have unveiled the trailer of the much-anticipated film. The trailer comes five months ahead of its theatrical release in December.

The Avengers will be returning after the 2019 movie Endgame. Doomsday trailer gives a peek into the next chapter of the MCU. The film will see Robert Downey Jr. return to the MCU, but as Doctor Doom. He will be seen in an epic battle against Earth’s mightiest heroes led by Thor. The trailer sees the reunion of several superheroes. However, the trailer ends with a surprise moment. Steve Rogers, aka Captain America, returned and briefly interacted with Thor. The God of Thunder is surprised and shocked at Steve Rogers’ appearance, but his summoning of Mjolnir clears things up.

The movie serves as the first part of Marvel’s Multiverse Saga finale, setting the stage for Avengers: Secret Wars. Its ambitious scale, unexpected casting and multiversal stakes have generated immense fan excitement worldwide.

Decoding The Trailer

The trailer of Avengers: Doomsday has already set up massive expectations. We see the Avengers and X-Men, the Fantastic Four, arrive in this reunion-style trailer that keeps you hooked. Doctor Doom is described as a very powerful enemy, one that Thor says they have never witnessed before.

The highlight of the trailer has been Steve Rogers’s return as Captain America. We see him on the screen as Thor hopes for a miracle. However, there are theories floating that it might not be the real Steve Rogers.

A theory by Marval Mania on X suggests that Steve Rogers is never long-haired and that the one shown in the trailer is, in fact, Hydra Cap. The theory suspects that Hydra is working with Doom, as in the comic, Hydra Cap ‘lifted’ Mjolnir through deception.
