Jeremy Renner and Original Avengers React as Chris Evans Drops Avengers: Doomsday Trailer

Chris Evans dropped a fresh Avengers: Doomsday teaser, and the original crew basically turned into the street team. It is a quick clip, but the ripple effect across the old guard was loud.

Who boosted the trailer (and where)

• Jeremy Renner shared it on Instagram Stories and reposted Marvel's X tweet on December 24, 2025, adding: 'Very cool.' (yes, with clapping emojis)
• Robert Downey Jr. put the trailer on his Stories too. He has been regularly posting Doomsday teases lately and recently shared a poster for his new movie on Instagram
• Chris Hemsworth and Tom Hiddleston also shared it, which is a nice full-circle touch considering Thor and Loki kicked off the MCU's first big brotherly feud
• Directors Anthony and Joe Russo posted it on their joint Instagram with a very pointed caption:

'The character that changed our lives. The story that brought us all here together. It was always going to come back to this...'

What is actually in the teaser

It is Evans back as Steve Rogers/Captain America, plain and simple. We see Steve come home to the same house we last saw him share with Peggy at the end of Endgame. Then it gets unexpectedly tender: Steve is holding a sleeping baby.

Smash cut to black and the text: 'Steve Rogers will return to Avengers: Doomsday,' followed by a countdown to the release. The message is not subtle — this movie is picking up Steve's thread from where Endgame left him.

The theory everyone is chewing on

Here is where it gets spicy. A well-known scooper, MyTimeToShineHello, claims Steve's time-hop to live with Peggy triggered Incursions — Marvel-speak for universes colliding — which puts him on a collision course with Doctor Doom. Their post on X spelled it out:

'When Steve went back in time to go live with Peggy he created the Incursions so now Doom wants him dead.'

That has snowballed into a fan theory that this sets up a straight-up Robert Downey Jr. vs Chris Evans showdown, with some speculating it might end badly for Steve. The chatter even goes as far as suggesting Downey Jr.'s Doom could come out on top. File all of that under speculation for now, but given the title and the stakes, it would not be shocking if the movie leans into something that bleak.

So... is Hawkeye in this?

Probably not. Despite fans hoping for a Clint Barton cameo, Jeremy Renner says he is not in Doomsday or Secret Wars. On The Breakfast Club, he was asked point-blank and answered: 'No, damn no.' He also reiterated that thing he said about being offered half his salary for a potential Hawkeye season 2. When the host joked Marvel could just hire an alternate-universe Hawkeye at half the rate, Renner shrugged it off: 'If they want to do that, they can go ahead by all means.'

He is still cheering from the sidelines, though. When Downey posted the Doomsday poster, Renner commented: 'I am sure you will crush it!!!' Between that and his social posts, it seems safe to say he is not in the movie.

Worth noting: Renner has been dealing with some offscreen turbulence. His filmmaking partner Yi Zhou accused him on Instagram of unsolicited behavior and said he threatened her; Renner forcefully denied the allegations. Given the timing, Marvel may prefer to steer clear — at least for now.

Bottom line

Evans is officially back, the Russos are clearly emotional about it, and the cast is boosting the signal like it is 2012 again. If the rumor mill is even half right, Doomsday is aiming for big, messy multiverse consequences — and maybe a brutal Steve vs Doom reckoning.

Avengers: Doomsday opens in the U.S. on December 18, 2026. How are we feeling about Steve Rogers coming home with a baby and a target on his back?
