After a series of leaks and a week-long run exclusively in front of Avatar: Fire and Ash in theaters, the Avengers: Doomsday teaser trailer confirming Steve Rogers / Captain America’s return is online.
Marvel officially released the teaser trailer today, December 23, with a Thor teaser trailer set to replace it in theaters this week. (The Thor teaser trailer leaked overnight, as this Captain America trailer had last week.)

— Avengers (@Avengers) December 23, 2025As IGN reported last week, the trailer begins with a figure on a motorbike pulling up to a familiar-looking 1950s house, which Marvel fans may recognize from Avengers: Endgame's closing scene. Inside the house, the figure is revealed to be Chris Evans' Steve Rogers, as he folds away his Captain America uniform and picks up a baby, which we assume is his. On-screen text then reads: "Steve Rogers will return in Avengers: Doomsday." We then get the countdown to Avengers: Doomsday's release date in December 2026, alongside a Doctor Doom-themed Avengers logo.

Doomsday may explain how Rogers managed to get back to the main MCU reality in order to hand his shield over (according to MCU time-trel rules, he should technically be in a new branch of reality instead).
The character was one of the original Avengers and played a key part in the $2.7 billion-grossing Avengers: Endgame. Hing the original Captain America back will undoubtedly be a huge audience draw, especially for those who he lost interest in Marvel over the past few years amid a string of underwhelming entries in its Multiverse Saga.
However, some he criticized Marvel's decision to bring Steve Rogers back into the fold as a "desperate" attempt to win back audiences at the expense of newer characters, and especially Anthony Mackie's Sam Wilson. It's a point of discussion IGN has also expanded upon, suggesting it has exposed Marvel's failure to introduce more fan-forite characters in the years since Endgame.
The Most Surprising Avengers and Marvel Characters Not Announced for DoomsdayIn a post on Instagram, the Russo brothers, who directed both Avengers: Infinity War and Endgame, issued a statement on Steve Rogers' return: "the character that changed our lives. The story that brought us all here together. It was always going to come back to this…"
Chris Evans reunites with former co-stars Robert Downey Jr. (Doctor Doom) and Chris Hemsworth (Thor) for Avengers: Doomsday. A recent report suggested that four separate trailers would launch over four weeks, in a move designed to encourage repeat viewings of Avatar 3 and keep audiences entertained with a series of big reveals. Thor is reportedly up next, with a Doctor Doom-focused teaser allegedly set to follow next week.
Avengers: Doomsday hits theaters December 18, 2026. Avengers: Secret Wars follows a year later.
