15 Marvel Movie Fan Theories That Are So Good, They Could Probably Lift Mjolnir (2023)

"Steve Rogers was selected not just for bravery, but for displaying intelligence beyond the other soldiers and being clever. So, I think S.H.I.E.L.D. played an old baseball game on purpose because they wanted to make sure the original super soldier was still entirely with it.

If he hadn't noticed that the date had already passed, it would have been cause for concern. It was likely the first of a few subtle tests they planned to do to make sure he wasn't too damaged after being frozen in ice for 70+ years, but he passed their first test immediately."

"My theory is that there's a reason why the language in both of the movies in this franchise feels incredibly juvenile. I believe that it's because we're actually hearing it all the way Peter Quill hears it through his universal translator, which is mentioned on screen in the first movie's mugshot scene.

Quill was taken from Earth when he was only 8. He probably stopped actually learning English shortly after, since he was traveling to all different planets that likely didn't speak any Earth-bound languages. As such, his language (and all of the language he heard) is stunted to that of a pre-teen boy. Additionally, any profanity he knows likely would've come from movies and TV shows he saw before he was kidnapped."

"Something fans constantly bring up as a plot hole with most incarnations of Spider-Man is how he can both create and easily repair his high-quality costumes, being that he's a poor teenager with no other experience in sewing or costume design in general.

I think the answer to this 'plot hole' is easy when you consider that the spider bite may have simply given him another power — seamstress skills on par with those of a spider spinning its own webs. This could also be spun (pun intended) to apply to how he knows how to easily produce non-organic webbing."

"I've seen a lot of people talking about how the Soul Stone works to preserve souls, and how you can exchange a soul for a soul as a possibility for why Natasha might be brought back eventually, but I think it's actually more simple than that:

I don't think Captain America ever went back to 'return' the Soul Stone. How could he? What was he going to do — toss it off the cliff? If the idea was to limit disruption to the alternate timeline, that wouldn't work. When Thanos got there in the other timeline, he would just find a stone and wouldn't need to sacrifice Gamora. He could just profit off Black Widow's sacrifice. This would completely screw up all kinds of things going forward in that timeline.

So, instead, I think Cap went back and stopped Clint and Natasha when they landed on the planet. He told them what was going to happen and explained that for things to work out, Nat would have to remain on the planet as if she had died. She could set her suit's return point to after the final battle, so as to make sure she didn't interfere with the one ideal timeline where Thanos was defeated. Clint's grief is still real as he has basically just abandoned her on another planet and has no clue if he'll see her again.

We know that when a timeline is changed by removing an infinity stone, it creates a parallel one without the associated infinity stone. We know that returning the stone will return the reality back to the main timeline, or effectively stop it from branching at all. This was explained by the Ancient One and Banner. It stands to reason that stopping the infinity stone from being taken would accomplish the same thing, effectively eliminating that branch from ever happening and restoring that alternate timeline to the original.

So, in the end when Hulk snapped, he couldn't bring Nat back because she is still alive!"

"In the comics, when Iron Man died, his consciousness became an A.I. while his body died. Then, Iron Heart took his place. I believe a version of this is what's going to happen in the MCU as well.

At the end of Avengers: Endgame, the 'hologram' of Tony turns to face his daughter, Morgan. He faces her exact position, as if he knew she was there. A hologram doesn't just do that.

So, my theory is that Tony's consciousness was backed-up into his Iron Man helmet before his 'death,' and he remains alive as an A.I., similar to the comics."

"Both at the end of Guardians of the Galaxy Vol. 1 and during the opening battle scene of Guardians of the Galaxy Vol. 2, Baby Groot was getting his groove on behind Drax's back. Then, when Drax looked at him, Baby Groot froze, at which point Drax appeared to no longer see him. Almost like he'd vanished.

My theory is that Drax eventually came to the realization that things that don’t move (or move incredibly slowly) are essentially invisible to him (similar to how the vision of the T-Rex is described in Jurassic Park).

What Drax didn't realize, however, was that other species don’t have this same handicap. So when he tried his hilarious invisibility bit in Avengers: Infinity War, he was unable to comprehend why it was so absurd to the others."

"I'm not talking about the comics, just strictly the MCU:

I believe Stormbreaker was a weapon forged for Thor, but not for Thor to wield. It was made to handle Thor, if necessary. Odin knew what had happened with Hela, and the similarities to pre-Thor movie Thor and Hela were quite similar: vain, warmonger-ish conquerors.

Odin saw the parallels and knew what he would have to do. If Thor ever got out of hand, Odin would have the perfect tool to combat Thor. Not kill him, but break him with a weapon more powerful than Mjolnir.

An axe made, literally, to break the storm."

"I had this idea for quite a while, but I noticed that M’Baku was able to run at the same pace as Captain America, Thor, AND Black Panther during the charge against Thanos’s army in Endgame.

This got me thinking: when T’Challa and Shuri were dusted in Infinity War, who ruled Wakanda during the five years? My theory is that M’Baku took the throne and became the Black Panther during that time. Black Panther established that — at the very least — M’Baku was a match for T’Challa, as seen in the waterfall scene for the throne of Wakanda. Then, during the battle in Wakanda in Infinity War, both Cap and Black Panther out-paced M'Baku (and their own army) against the marauders.

He is the most capable person to lead Wakanda in their darkest time, and with the royal line of succession broken, I think he may have taken the throne — not out of personal reasons, but out of necessity."

"My theory is that Tony Stark's snap sent Thanos and his army back to 2014, instead of killing them. So, the Thanos we see in Infinity War and Endgame are the same iteration of Thanos.

Throughout Infinity War, Thanos constantly talks about destiny and inevitability. Some of Thanos's first lines in Infinity War are 'I know what it's like to lose. To feel so desperately that you're right, yet to fail nonetheless. It's frightening. I ask you, to what end? Dread it, run from it, destiny arrives all the same. And now it is here.'

Which failure is Thanos talking about? Sure, he could be talking about the starvation on Titan, OR could he be talking about the events of Endgame, which for him have already happened? Is it possible Thanos already knew how his story would end? He knows that he will successfully obliterate half the universe, he knows Thor will behead him, and he knows that all his work will be undone — but he does it anyway, believing it to be his destiny, and that his actions are inevitable."

"For those of you who haven’t seen Avengers: Age of Ultron in a while, one of the standout moments of the film is Vision casually lifting Thor’s hammer when he’s first created, then outright wielding it later during the fight in Sokovia. At the end of the film, Steve and Tony are arguing with Thor about how he pulled it off. Their two theories are that either 1) as a machine, Vision doesn’t count as a living being and can lift the hammer like an 'elevator' could lift it, or 2) Vision's a genuinely pure soul who — as a being on 'the side of life' — is worthy of protecting the human race.

Vision’s up there with my favorite Avengers, so I’m sorry to do him dirty like this, but...my theory is that Avengers: Endgame kind of implies that the 'machine' theory was the right one all along and only Thor and Steve are truly worthy.

Steve lifts the hammer during the final battle. Like Vision, he can call the hammer to him and swing it around — but UNLIKE Vision, he can actually summon lightning, and uses that as part of his attacks. Now, remember the inscription on the hammer:

'Whosoever holds this hammer, if he be worthy, shall possess the power of Thor.'

Thor’s power is lightning. It's not being able to lift the hammer. When Thor uses his power, the hammer works as a conduit for that. He doesn’t get the lightning FROM the hammer itself and Thor: Ragnarok establishes that. The lightning is the power of Thor, and the lightning is what Steve can use — whereas Vision can’t."

"I believe Thanos knew the price that had to be paid for the Soul Stone, which is why he 'adopted' Gamora in the first place, knowing that he had no family or loved ones of his own. However, in raising her, he found himself genuinely coming to love her and could not bring himself to harm her. So, my theory is that he adopted Nebula and planned to send Gamora and Nebula to seek out the Soul Stone together with the intention of Gamora sacrificing her sister.

This is why he constantly pit the two against each other in combat, to be absolutely certain that Gamora would always be the victor. Every time that Nebula lost, he would replace a part of her body with cybernetics — not to make her stronger, but the opposite, making sure she would always be at a handicap against her sister. This would also foster a deep resentment in Nebula, ensuring that she would be willing to fight to the death, even if Gamora tried to refuse. This remained his plan until he realized Gamora turned on him and he had to dispose of her.

This would also explain why Nebula seemed to know the price of the Soul Stone, but not Gamora. In Infinity War, Nebula commented that Thanos returned from Vormir with the Soul Stone, but not Gamora, and instantly knew her sister was dead."

"Every single fan theory that was posted online before Avengers: Endgame was released was one of the many possible futures Doctor Strange saw in Avengers: Infinity War. So, they're all correct!"
