Robert Downey Jr.'s terrifying Doctor Doom finally arrives, but it's Chris Evans' surprise return that has Marvel fans talking.

Marvel Studios has finally released the first full trailer for ‘Avengers: Doomsday’, giving fans their biggest look yet at the MCU's most ambitious crossover since ‘Avengers: Endgame’. While Robert Downey Jr.'s transformation into the terrifying Doctor Doom is a major highlight, it's Chris Evans' unexpected return as Steve Rogers that delivers the trailer's biggest surprise.
The trailer opens with Doctor Doom, played by Downey Jr., emerging as the MCU's next great villain. Cloaked in his iconic green hood and metal mask, Doom sets a multiversal war in motion, bringing together heroes from the Marvel Cinematic Universe, the X-Men films, and the Fantastic Four universe for an unprecedented showdown.

From there, the trailer races through several major crossovers, teasing battles fans have long imagined.

Tom Hiddleston also briefly appears as Loki in his TVA attire.
The trailer's standout moment arrives when Thor tells the assembled heroes they will need "a miracle." That miracle turns out to be Steve Rogers, making his first appearance since ‘Avengers: Endgame’.

Thor also takes centre stage emotionally, rallying the heroes before facing Doctor Doom himself. The closing sequence makes one thing clear, Doom is unlike any villain the Avengers have faced before, overpowering Thor with ease and establishing himself as a threat beyond even Thanos.
