14 Ant-Man Fan Theories That Are Actually Plausible

From Redditor u/sush_dak:

Hear me out mates. Scott Lang has no idea about the events of Infinity War. All he knows is that Captain America and team are on the run from the government and the only legal Avengers (according to the Sokovia accords) are Iron Man, Spider-Man, War Machine, Vision, and maybe Black Panther. Who he might find in the head quarters. So when he comes out of the quantum realm and discovers that his friends have disappeared. He rushes to the Avengers' head quarters to get help or information from Tony Stark .

Proof:

1. He keeps introducing himself as Ant-Man. We are centain that Steve Rogers and friends know him well.

2. In Civil War when Tony comes to the prison to visit the captured avengers, he refuses to recognize Scott Lang. Hence Scott Lang keeps introducing himself as Ant-Man.

Conclusion: 

Scott Lang expected Tony Stark or the pro-Sokovia Accords Avengers in the Headquarters.

So in Ant-Man and The Wasp, we learn that Janet was in the Quantum Realm for 30 whole years and that it was 30 years for everyone as well. But then in Endgame, we learn that Scott was in the Quantum Realm for 5 hours but for everyone else, it felt like 5 years. I remember when Endgame came out, a lot of people were confused and why it was different for Scott. Here's where my theory comes in. So when Scott in going into the QR to get the Quantum Healing Particles for Ghost, Janet says to Scott, "Don't get stuck in a Time Vortex." There were lots of theories that Scott would go into one of them and come out in the future and then some other stuff would happen but as far as we know, Scott didn't interact with them. I think that when Janet was in the QR, she interacted with a Time Vortex because she didn't know anything about the place and then the Time Vortex screwed with time for her, making the time in the QR equal to the time for everyone else. Whereas Scott didn't mess with a Time Vortex because Janet told him not to which then leads to time being disproportionate from time for everyone else which is why 5 years was 5 hours for Scott.

From Redditor u/Ariakis:

Scott does remember what he did at the end of the movie. Anyways, my theory is that Scott actually does remember how he reversed the shrinking to come back from being subatomic but, lies about not remembering to prevent Hank from going to look for his wife, knowing how impossible that task would actually be.

From Redditor u/Isaac_Masterpiece:

In Endgame, a bunch of kids walk up and want to get a selfie with Professor Hulk while he's having a discussion with Scott Lang. Scott attempts to also get some recognition, and tells the kids, mournfully, "I'm Ant-Man!"

The kids clearly don't recognize him.

Even though Professor Hulk keeps trying to insist that Scott is also a superhero and convince the kids to do a selfie. It's an awkward, wonderful scene.

But, I think the reason they don't recognize him is because Ant-Man isn't widely known about. Giant Man, on the other hand, showed up in that harbor and raced down the street using a truck like a scooter. It's likely that had Scott identified himself as Giant Man, the kids would have, at the very least, known who he was.

From Redditor u/twitchedawake:

Hank Pym is a liar. We're talking about the movie, cause in the comics pym particles are basically speed force for size. This is in response to how everytime Ant-man is mentioned, someone will bring up how the powers are either ridiculous and unscientific or the more understandable issue of how the powers were inconsistent with how Pym described them.

But I like to think either Pym lied, which he has been known to do, quite often I might add, or that he's simply wrong and his discovery of pym particles was a straight up accident like teflon, and that hes only just scratching the surface of them, and his current explaination is just his working theory. His description was that they change size and density by increasing and decreasing the space between atoms and electrons. That works scientificly, as denser things have atoms tightly packed together, ala stones and lead, while things like helium and neon are futher apart. And it explains a few scenes like him cracking floor tiles and punching through ceilings, but its obviously wrong when it comes to the tank keychain and dog-sized ants and Thomas the tank engine, which many many many people have pointed out.

From Redditor u/sonofaresiii:

One of the most common complaints I see with Ant-Man is that the density changes don't make sense. When Ant-Man is tiny, he arbitrarily has density relative to his size, or retains his normal density packed into a tiny form. And that's a fair complaint. It certainly is inconsistent. There are plenty of theories out there - Hank Pym lies about it (but the Yellowjacket guy describes it exactly the same, so there's no reason why Hank's bitter rival would adopt the exact same story in support of Hank, and lie for no reason to investors), or that Pym Particles are just wacky.

But there is something we see with consistent density changes-- everything besides Ant-Man (and the Yellowjacket/Wasp suit). Hank carries a tank around on his keychain that, when enlarged, works as a full tank. He carries around a whole building like a suitcase. Thomas the Tank Engine enlarges and crashes through a wall. Everything that is only enlarged or minimized but doesn't use the suit takes on density relative to its size.

But anyone wearing an Ant-Man suit... doesn't. Or does so inconsistently.
