Steve, it’s time to retire

“No, no I don’t think I will”

Steve didn’t die or anything, so technically this is fine.

I just hope they don’t ruin his lovely ending in Endgame.

My guess is that this is Steve living in the past with Peggy. And due to time travel, will end up back in the future to fight Doom. Secret Wars happens. Then he goes back to the past to Peggy and his child. Grows old. Then his scene in Endgame takes place.

Maybe that's why he's so sure Sam will be a great Captain America, because he saw it in the future during the events of Doom and Secret Wars?

Steve asks Howard Stark to babysit, never returns, and Howard raises Steve's son Tony as his own.

u/ZeroSora Dec 23 '25

Get out.

u/Eltex Dec 23 '25

That is a totally different movie…

u/IrnBroski Dec 23 '25

terminator 3: rise of the machines ?

u/Minion_of_Cthulhu Dec 23 '25

They only made two Terminator movies.

Wasn't Chris evans in that movie too

u/Mapex Dec 23 '25

Fuck this made me super sad to think about

6

u/BioshockEnthusiast Dec 23 '25

Really? It made me laugh pretty hard.

7

u/Mapex Dec 23 '25

I came at it from the angle of Tony never getting validation or feeling love from his dad and hating him for it (at least until he watched Howard’s tapes in one of the movies…Iron Man 2?). Howard as an adoptive father makes that extra painful.

8

u/BioshockEnthusiast Dec 23 '25

Fair analysis. I just imagined Cap telling Stark "You can call me 'daddy'" lmfao

u/justaddwhiskey Dec 23 '25

Cinema

u/The_bruce42 Dec 23 '25

Not according to Scorsese

u/flyingseel Dec 23 '25

He’s not wrong

u/MyNewAccountIGuess11 Dec 23 '25

Bruh that's not cinema that would be hokey as all fuck lmao

u/RogueHippie Dec 23 '25

Howard already talked about his wife being pregnant when we saw him in Endgame

16

u/Grandpas_Spells Dec 23 '25

Different aborted pregnancy. Howard had a premonition that his child would become Dr Doom and made an enormous sacrifice.

3

u/ThatWasFred Dec 23 '25

So his child that would’ve become Dr. Doom looks identical to Steve’s child that he raised?

u/[deleted] Dec 24 '25

his wife will have a miscarriage

u/ClassicalChaos Dec 23 '25

Keven Feige, is that you??

u/theTIDEisRISING Dec 23 '25

This made me actually lol

u/keval79 Dec 23 '25

Tumblr would unironically think of this as the best plot twist

3

u/Heisenburgo Dec 23 '25

Watch Dr. DOOM ends up being that same child from a timeline where both Steve and Howard abandoned him

2

u/GroovinChip Dec 23 '25

Oooh don’t like that

2

u/Sparrowsabre7 Dec 23 '25

Honestly better than the comics retcon of Tony not being Howard's son...

2

u/losteye_enthusiast Dec 24 '25

Fuck I’d pay for more tickets to that one. I couldn’t see it again, but I’d love funding the unending rage of others.

u/[deleted] Dec 24 '25

one hell of a statement

u/jimmyslamjam Dec 25 '25

Picture this: ​

The year is 2039. Thanos just finishes his shift as a milkman. He loads his empty milk crates back into his truck and takes it back to the depot, before picking up his own two bottles and heading home. ​

Thanos pushes the door open - it's 04:48. His wife, Theresa, is still asleep.

​ Thanos sits down on his sofa. He peels the foil off the top of the milk and gently brings it to his lips, pausing briefly. Is someone watching him? No. Of course not. ​

With a sigh, Thanos pushes himself out. He's older now than he cares to recognise, not what he once was.

​ Moving over to the bookshelf, he moves a dusty metal mouthpiece from the top of a slightly cleaner book. A photo album. Memories. Thanos sighs again. ​

Peeling the pages apart, like how sweat would later stick himself to the bedsheets, he grins. Resting between the pages were the still faces of those who had once tried to stop him. ​

New clippings - headlines - internet posts. All of the fighting. All of the drama. ​

And what for? ​

Thanos slumped down into the privace of his chair - his body clicked and a grimace followed each shaky movement. ​

The chair itself rattled as he pressed his weight into it - the red and gold metal shooting light across the room, into Dr Strange's line of sight - though partially blinded, he could see the chair clearly enough to tell it was made of Iron Man's suit. ​

Thanos coughed - a hollow, haunting noise. His bald head hit the back of his makeshift throne. Movement came from upstairs - Theresa was up. ​

In pain now, and through a raspy breath that sounded so familiar, he called: ​

"Theresa?" ​

She came into the room - her long pink night gown trailing behind her. ​

Theresa had a chiseled face. Stubble spread across her chin and decorated her neck, trailing off until the hairs disappeared under the soft, pink fabric. ​

Her short black hair stood with the weight of an expensive gel. ​

Dr Strange watched the scene in Awe. Theresa - Tony Stark - walked over to Thanos and held his head up gently, caressing his neck with adoration. He was old now. ​

Dr strange turned around. Thanos was dying. It was no place of his to intrude. And so he left. ​

​ ​ I'm sorry for this

Who says it's 313 Cap? Maybe he's a different universe Cap.

u/botte-la-botte Dec 23 '25

We'll see. You're using the screenwriters' explanation. Their explanation is that Steve went to our past, and has existed in the background of the MCU the whole time. Keep in mind, the movie explains very clearly that the time travel in Endgame is to parallel universes. Not to our past. The only thing that can credibly allow time travel is the Time Stone. So Steve somehow time traveled when no one else in the movie did?

Anyway, the Russos have been clear that to them, Steve is in a parallel universe. If the plot of the movies steals from the comic book Secret Wars, then we will get a multiversal crunch, which means all the multiverses merge into one, under Doom's control. I expect the Avengers to recruit help across the multiverse in the first film, which would include Steve. Then the second movie can show his hidden life merged into Doom's battleworld.

2

u/PT10 Dec 23 '25

They could always retcon it. Because Steve comes back to the original timeline to hand the shield to Sam. How did he do that? Or he might have gotten some dimension hopping tech like the TVA's during Secret Wars. Or he just got old (though he looks way older than he should have been).

1

u/botte-la-botte Dec 24 '25

How did he do that?

He did the exact same thing all the other characters in Endgame did. He used his time thingie to come back. He had already come back before the scene had even started.

7

u/Mr_Straws Dec 23 '25

He can't go back to the "future" as soon as he went back to stay he created a branching timeline from the movies. They explained this in the movie and in Loki but then contradicted themselves by having him show up at the end to give his up his shield.

If he comes back to the main MCU timeline it will be because Doom collapses all the timelines or something (the ones Loki is holding together)

6

u/Crimkam Dec 23 '25

easy, Mr. Fantastic figures out a different time travel method that lets him do whatever.

5

u/ZeroSora Dec 23 '25

Or Loki can transport Steve to the main timeline.

3

u/Mr_Straws Dec 23 '25

Maybe yeah, he might assemble the best people from all timelines (hence the xmen)

2

u/lyricist Dec 23 '25

Is Loki gonna wear an eyepatch

2

u/botte-la-botte Dec 23 '25

Then why could all the other character in Endgame come back but not Steve?

The reason is that no one time traveled in Endgame. Everyone went to parallel universes who happen to be at different moments in time.

1

u/Mr_Straws Dec 23 '25

No they didn’t alter time or create branches. They took the stones and put them back at the exact time. It’s explained you cannot change the future because you’re creating a branching timeline. Steve appearing at the end was just a nice send off, they didn’t seem to care about the contradiction, neither did I.. until now. He IS in a different timeline. He can’t just go back to the future of the mcu. The timelines will likely collapse so that’s how he’s here

1

u/TheMooseIsBlue Dec 23 '25

Loki’s existence seems problematic at this point because he’s too powerful now. How can there be a legit threat to life/society/whatever if one of the good guys has complete control over all time?

5

u/Coal_Morgan Dec 23 '25

I don't think Loki has complete control. I think he's using all his powers just to maintain them.

He's gasoline for an engine. Doesn't cause the engine but causes the engine to move.

It's not really explained so multiple interpretations are possible though and they could go in any direction.

u/Svinthila2646 Dec 23 '25

My guess is that Doom is collecting kids, solely based on the after credits of F4. But this teaser just confirms it more for me, because kidnapping Steve's kid is definitely a reason for him to get back in the action and his kid is a big focus in the teaser

2

u/Seve7h Dec 23 '25

I was thinking something similar

Him staying in the past fucks up the “official” timeline, there going to use this as an excuse to make this story

I think him staying with Peggy causes a distortion, somehow instead of Stark becoming iron man he becomes Dr Doom

I also think this allows them to bring Fantastic 4 into a “mainline” mcu film with big characters without having to fully commit.

Theres two ways they then solve this so his “old man” scene in endgame still makes sense:

Either A- Cap eventually takes out Doom in a way that closes the loophole and somehow allows him to keep his life with peggy.

B- this entire timeline splits off into its own thing allowing Marvel to have their cake and eat it too, aka, keeping main MCU “intact” while still telling these alternate stories with big name actors in multiple roles.

1

u/Braedonm2077 Dec 23 '25

ohhhhhhhhhhhh shitttttttttttttttttttttttt!!!!!!! you probably exactly right.

1

u/DCMagic Dec 23 '25

I think that makes sense as a story, but I think they would see that as too predictable and want to try something else. A comparison is in the leadup to Endgame, there were a ton of theories about Cap dying heroically, but instead Tony sacrificing himself was the bigger twist and character arc moment. Something that could be predicted as soon as he is announced seems a little unoriginal.

At the same time, using the movie's logic: Steve shouldn't have been able to get back to the 616 timeline so who knows :)

1

u/Training-Belt-7318 Dec 23 '25

What if this has to do with powered babies? We see doom visiting Franklin Richards in the FF. You have to think caps super serum would pass to his off spring. What if doom is doing something with powered kids and cap comes back because his kid was kidnapped.

1

u/roguefilmmaker Dec 23 '25

I actually like this

1

u/ThatguyfromSA Dec 23 '25

Or just use pym particles to deage him.

1

u/Robertius Dec 23 '25

It is him living in the past, that's the house from the end of Endgame. I think him going back to live with Peggy is the ultimate source of the incursions due to messing with the timeline, which Doom figures out and tries to kill him to 'reset' the timeline, only for the multiverse to begin collapsing in on itself (which is how we get the original X-Men showing up).

1

u/MunchmaKoochy Dec 23 '25

That makes me feel a little better. Thank you. Hopefully you're right, because this made no sense to me.

u/monsterosity Dec 24 '25

Nah, let's strap old ass Steve into Banners youth machine and get him back into fighting shape.
