CRAZY THEORY: The Thor vs Doom trailer scene is actually a time-slip fakeout
Hear me out. I was rewatching the trailer, specifically that insane shot where Thor goes to strike Doom and Doom just effortlessly stops it. I have a massive theory about how this scene actually plays out in the movie, and I think Marvel is hiding a huge twist in plain sight.
Here is how I think the sequence actually goes down:
The movie opens or reaches a critical first-act climax where Doom just completely levels New York City. The Avengers are getting absolutely routed. In the chaos, Captain America steps up, wielding Mjolnir. Cap manages to get a massive, clean hit on Doom, launching him across the battlefield.
Doom crashes hard into the rubble and ends up landing right at Thor’s feet. Thor stands over him, delivers that cold piece of dialogue from the trailer, and then starts his attack. But here is the twist: Thor actually kills doom then and there and not the scene we watched in the trailer.
Later in the movie, we find out Doom has mastered time-slipping (similar to what Loki figured out, or maybe through stolen TVA/Kang tech) and is much stronger now. The movie shifts to Doom's perspective, and he time-slips back into his own body right to the moment he gets knocked to Thor's feet in NYC.
Because he has already lived this exact moment and knows exactly what Thor is going to say and do, Doom is ready for it. Thor says his dialogue again, swings for the kill and that is when Doom catches the weapon and stops the attack, which is the exact shot they used in the trailer.
