Avengers: Doomsday Trailers Breakdown: Every Reveal and Hidden Detail You Missed

Marvel is doing something a little cheeky with Avengers: Doomsday: four character teasers, drip-fed in theaters alongside Avatar: Fire and Ash over four weeks. Officially, only one has actually hit screens. Unofficially, two low-res leaks are making the rounds, and they both answer the question everyone asks first: yes, Chris Evans and Chris Hemsworth are back.

Quick status check

• Plan: four character-focused teasers playing with Avatar: Fire and Ash across four weeks; only one has been officially shown so far.
• Leaks: two grainy teasers centered on Steve Rogers and Thor are online; they mostly confirm the characters and set a tone.
• What’s next: fans expect the remaining teases to spotlight Doctor Doom. The Doom character tease is expected around New Year’s Day, with a broader Avengers: Doomsday trailer targeting later in January 2026.

Steve Rogers is back... with a baby

The first leaked teaser (which has been verified as legit) catches up with Steve post-Endgame, after he returned the Stones and chose the long way home with Peggy. It’s quiet, sentimental, and very intentional about what it’s showing and not saying.

What’s in it: Steve parks a motorcycle, steps into a modest home, takes a long look at his old suit, and then cradles a baby. A sparse piano version of the Avengers theme plays. The button: a stark title card reading 'Steve Rogers will return in Avengers: Doomsday.'

That baby is the headline-grabber, but here’s the wrinkle: in the mainline Marvel comics (Earth-616), there isn’t a notable storyline where Steve and Peggy have a child together. Steve’s kids pop up in alternate realities and with different partners. Translation: this could be an alternate-timeline situation, or Marvel is just doing its own thing. Also worth flagging: there have been reports of a scene with Steve, Peggy (yes, Hayley Atwell), and Doctor Doom (Robert Downey Jr.) being filmed for this movie, which obviously pours gasoline on the speculation fire about how Steve and Peggy fit into all of this.

Thor’s teaser leans hard into Dad Mode

Teaser two puts Thor in the woods, praying for strength before heading into a fight he clearly does not take lightly. The focus is on him and his daughter, Love — the resurrected child of Gorr the God Butcher whom Thor adopted at the end of Thor: Love and Thunder (played by India Rose Hemsworth). The vibe is somber, protective, and a little haunting.

'Father, all my life, I have answered the calls of honor, duty, and battle. But fate offered me something I had never hoped for. A child, a life preserved from the storm. Grant me the strength of all fathers. So that I can fight once more, defeat a new enemy, and return to her. Not as a warrior, but as a protector. They do not know war, but worry. The kind I have never known. I beg you, father, hear my prayer.'

Thor praying is a strong image, especially when he’s the God of Thunder. The implication is clear: he’s gearing up to face Doom, and he’s taking nothing for granted. The teaser also shows Love tucked in as Thor says his goodbye, plus a quick look at Thor’s close-cropped haircut that calls back to Infinity War. If you’ve missed that more battle-ready version of the character, that’s what this is selling.

So where does Doom fit in?

Robert Downey Jr.’s Doctor Doom has only had a blink-and-you-miss-it, obscured credits cameo so far — in The Fantastic Four: First Steps — but the plan for Doomsday seems obvious: use the multiverse as a door to bring back old favorites without undoing Endgame. That means variants, alternate branches, or timelines that rhyme with what we know, not rewrite it. It also helps square the circle on things like Steve and Peggy’s domestic life (and that baby).

The big questions the teasers are poking

These two leaks do not show much, but they say a lot. Both Chrises are in, the mood is heavy, and Doom feels like a problem that requires more than just punching. The fun speculation:

Does Downey’s Doom have a bone to pick with Steve for tinkering with time — possibly even for upending the peace Tony finally earned in Endgame? And if Steve lived out his days with Peggy, what does that mean for the version of Steve still frozen in ice in that timeline? Messy questions, which is exactly why the multiverse exists.

Avengers: Doomsday is a Marvel Studios production directed by Anthony Russo and Joe Russo, starring (among others) Chris Evans, Chris Hemsworth, and Robert Downey Jr. It’s currently set for December 18, 2026. Expect the real marketing push to kick in once those Doom teases land and the January trailer drops.
