AVENGERS: DOOMSDAY Leaked Trailer Features A Major Reveal That Could Shape The MCU's Future - SPOILERS

The first trailer - though it was really more of a character-focused scene than an actual teaser - for Avengers: Doomsday leaked online earlier today, and it finally confirmed one of the worst-kept secrets relating to the movie.

Spoilers ahead.

Yes, Steve Rogers (Chris Evans) will officially return to the MCU in Doomsday, and by all accounts, the former Captain America will take centre stage as one of the film's leads along with Doctor Doom (Robert Downey Jr.) and Thor (Chris Hemsworth).

Though Evans' name was not announced as part of this summer's big cast reveal, his involvement shouldn't come as much of a surprise to anyone who has been keeping an eye on the numerous rumors that have been doing the rounds since we first learned that Marvel Studios would pivot away from The Kang Dynasty following Jonathan Majors' assault charges.

Far more interesting is the reveal that Steve and Peggy had a child together in the alternate timeline that was created when The First Avenger returned the Infinity Stones and decided to remain in the past in Avengers: Endgame.

Rogers having a child is a concept that has been explored in the comics across several different timelines and realities. In the main Marvel Comics 616 continuity, Steve adopts the biological son of Arnim Zola, Ian Rogers, who ultimately adopts the Nomad persona. There's also the Ultimate Universe's Red Skull, and Sarah Rogers, aka Crusader, from an alternate What If? reality.

Of course, it's highly likely that this unnamed infant we see in the teaser will be an entirely new character, but his existence could still have significant ramifications of the future of the MCU. We know that T'Challa's son, T'Challa Jr., will eventually become the new Black Panther, and it looks like Thor's adopted daughter, Love, will also return.

Marvel Studios has a lot of options when it comes to continuing the legacy of the original Earth's Mightiest Heroes, and the likes of The Champions and the Thunderbolts, aka The New Avengers, are expected to carry the torch post-Secret Wars. Still, one can't help but wonder if the studio is keeping all bases covered by introducing more of the Avengers' actual children, as opposed to mentees that take up their mantles.

What do you make of the reveal that Steve and Peggy have a child in Doomsday? Let us know in the comments, and check out a new fan-made poster via Viscom Creative below.

Avengers: Doomsday and Avengers: Secret Wars were recently hit with significant delays, with Doomsday now set to arrive in theaters on December 18, 2026, and Secret Wars positioned for December 17, 2027.

Both movies will be directed by the Russo brothers, who also make their MCU return after helming Captain America: The Winter Soldier, Captain America: Civil War, Avengers: Infinity War and Avengers: Endgame

"Being able to create stories and explore characters within the Marvel Universe fulfilled a life-long dream of ours, and we discovered a powerful connection with audiences in each film that we made. We’re thrilled to collaborate once again with Kevin, Lou and the entire Marvel team to bring this epic adventure in storytelling to new and surprising places for both the fans and ourselves”, said The Russos in a statement after the SDCC panel.

Doomsday will star:

Paul Rudd as Ant-Man, Simu Liu as Shang-Chi, Tom Hiddleston as Loki, Lewis Pullman as Sentry, Florence Pugh as Yelena, Danny Ramirez as Falcon, Ian McKellen as Magneto, Sebastian Stan as Bucky, Winston Duke as M’Baku, Chris Hemsworth as Thor, Kelsey Grammer as Beast, James Marsden as Cyclops, Channing Tatum as Gambit, and Wyatt Russell as U.S. Agent

Along with Vanessa Kirby as Sue Storm, Rebecca Romijn as Mystique, Patrick Stewart as Professor X, Alan Cumming as Nightcrawler, Letitia Wright as Black Panther, Tenoch Huerta Mejia as Namor, Pedro Pascal as Reed Richards, Hannah John-Kamen as Ghost, Joseph Quinn as Johnny Storm, David Harbour as Red Guardian, Ebon Moss-Bachrach as The Thing, Anthony Mackie as Captain America, and, of course, Robert Downey Jr. as Doctor Doom.

"Continuing the legacy" with any character that isn't the og hasn't fared well for Disney... Reboot.

We need an article that goes into what make and model bike Steve was riding and what that means for the future of Disney.

Why is this the third article about exactly the same thing in the space of a day? Do you guys not bother to check your article content with each other?

@DrCigarettes - i see you are new here. That's how retarded writers here are for an easy buck

@vectorsigma - not new. Just enjoy calling out bullshit, so made an account and started doing so.

@DrCigarettes - oh a lot of us tried already. Journalistic Integrity is nothing here. Its clicks and revenue over that for these hack writers

TheFinestSmack - 12/15/2025, 6:24 PM
@DrCigarettes - They typically claim that they speak amongst themselves and plan out what articles they are all writing. But it's lately seemed to be the case where if one of them releases an article about something, the other will just claim some random scooper "said the same thing but slightly different" to barely warrant an additional article.

@vectorsigma - Tomorrow we'll get this same article, but with "in the background we can see a block of cheese in Steve's kitchen, and MTTSH is saying "this cheese is plant-based since Steve is now lactose intolerant, maybe, probably."

Doom should kill Peggy and the baby to really set the stakes.
TheVisionary25
TheVisionary25 - 12/15/2025, 4:39 PM
I honestly think Steve and Peggy having a kid is moreso just a plot device or so that further accentuates the theme of fatherhood that the film apparently has and if RDJ’s Doom is after Steve due to his decision to go back to the past causing an incursion that killed his family & world then I could see the latter going for a kind “eye for an eye” revenge by targeting Peggy and his son.

Granted , Steve has had sons & daughters in the comics throughout various alternate realities or even 616 so perhaps there could be a future there but I doubt it as of now!!.

@Orangeblack - guess we'll finally find out if Steve travelling back created a new timeline, or whether he always was the mystery husband (I prefer the former aka the homewrecker Steve theory)
Orangeblack
Orangeblack - 12/15/2025, 7:18 PM
@Vigor - hes not like physically in it. Bad choice of words. They mention him and they call for him when Peggy is dying

It’ll only shape the NCU’s future if Steve is back to stay.

I get they didn't reveal his name with the chairs to keep it a surprise, but I don't get revealing it here so (too?) early on. The trailer was bound to get leaked.
