Why was Captain Marvel not snapped? That's because she was pulling energy from the Stones to give her a power boost, which also explains why she didn't flinch when Thanos punched her.
The filmmakers wanted Tony Stark to be the one to put on the Gauntlet, snap his fingers, and sacrifice his life to save others as a conclusion to his story arc. Having Captain Marvel do it would not serve the narrative well. Couple of reasons. First, they already used it to do what they needed to do.
Captain Marvel's ability to keep Thanos from snapping had nothing to do with the latent strength she had from her powers. Instead, it was her power's ability to siphon off energy that made her able to face off against him.
In the movie Avengers: Endgame, why was Hulk having difficulty in going for a snap while Iron Man didn't? Two things. Hulk snapped half the universe back, and back to safety no less. Plus, he spent considerable effort wrestling with the Soul Stone to get Black Widow.
According to the duo, the family's closeness in the series is an indication that none of them were "blipped." "Well, I would assume that, seeing how the family dynamic is with them, I have a feeling that none of them got snapped," the duo said.
Imagine, Tony survived after End Game, he could have his own replicated Pym particles, had a time machine in his suit and even had access to each timeline in the multiverse. Dr. Strange believed if Tony Stark survived then sooner he will be the most powerful being in the universe.
The Blip occurs at the end of the film in Wakanda, where numerous characters are blipped, including Bucky Barnes, Nick Fury, Maria Hill, Wanda Maximoff, Peter Parker, Stephen Strange, T'Challa, Sam Wilson, Peter Quill, Groot, Drax, and Mantis.
Because the snapping or any other physical act wouldn't activate the power of the Infinity Stones – it's the mind that mandates what the stones do. So, even thought Thor was in the state to physically wield the power of the Stones, he wasn't in best mindset to send them clear instructions with what need to happen.
Hulk was able to survive because of his exposure to high amounts of gamma radiation, and if Tony was living with the power of the Tesseract lodged in his chest, the same logic should apply. If Iron Man was empowered by the Infinity Stones, using the Infinity Gauntlet shouldn't have killed him.
“Endgame” co-writer Stephen McFeely told Backstory Magazine (via Comic Book Resources) that Hulk's transformation from the snarling, angry brute into a sweeter, smarter version of the character was enough reason to hold off on a rematch between the two giant characters.
Captain Marvel, one of the strongest Avengers, is one of the few characters in comics who can actually lift Thor's hammer WITHOUT being worthy.
Which superhero did Thanos fear the most? Some might say Thor, or Captain Marvel, because they obliterated his forces and came dangerously close to defeating him.
She has spent up to 20 years blasting around the universe, serving as a hero to hundreds of planets. Since she's lasted this long, she probably hasn't lost much. She's used to being the most powerful person in the room, maybe on the planet. That can lead to more than just a little arrogance.
Now, it appears Captain Marvel almost certainly has the ability to destroy a separate Infinity Stone. As we saw in Captain Marvel, Carol Danvers gained her powers when Wendy Lawson's lightspeed engine, powered by the Space Stone (via the Tesseract), exploded.
Because Thanos is more than durable enough to tank her attacks. His best durability feat is enduring a power surge of unparalleled cosmic proportions from snapping the Infinity Gauntlet. When Thanos snapped his fingers, Earth became ground zero for a power surge of ridiculously cosmic proportions.
Unlike Tony Stark, Captain America wasn't wearing a sophisticated nanotech armor that would allow him to duplicate the Infinity Gauntlet. Thus he'd presumably have had to keep the Gauntlet away from Thanos, and then realize another snap was the only way to stop the Mad Titan after the Quantum Van had been destroyed.
We know that Gamora wasn't at Tony Stark's funeral - unsurprising considering that she didn't know him, really - so she must have fled after the battle was won.
TONY STARK
Nevertheless, the pair have hooked up with one another time and again. They even took a swing at something slightly more serious in SHE-HULK (2005), but the pair never last.
Bruce Banner's arm is fully healed after Avengers: Endgame thanks to She-Hulk: Attorney At Law. Although Hulk only made one appearance in Phase 4 before She-Hulk, Mark Ruffalo's cameo in Shang-Chi and the Legend of the Ten Rings raised several questions about his Marvel Cinematic Universe character.
Is Thor still worthy in Thor: Love and Thunder? It is pretty clear that Mjolnir chose Jane, not because Thor was unworthy, but because Thor's oath had instructed it do so. Sadly, the hammer cannot cure Jane's cancer, and can only transform and temporarily empower her.
Comic. Thor's Prosthetic Eye is a cybernetic prosthetic eye given to Thor by Rocket Raccoon as a replacement for Thor's right eye, which had been gouged out by his sister Hela.
Avengers: Infinity War introduced audiences to a brand-new weapon for the God of Thunder: an axe-hammer called Stormbreaker. Stormbreaker replaced Mjolnir upon the hammer's destruction in Thor: Ragnarok, and since Infinity War, it has been his weapon of choice.
Wanda tried her best to protect Vision from Thanos during the battle of Wakanda, but she was no match for the Mad Titan. (In fairness, Thanos had just acquired the sixth and final Infinity Stone.) Five years later, after Wanda had been blipped out existence with half the universe, the Avengers brought her back to life.
Thanos is able to activate the Infinity Gauntlet, snap his fingers, and teleports away. Rocket watches helplessly as Groot dissolves into dust alongside half of all living things in the universe. Groot uttered one final "I am Groot," which director James Gunn revealed translated to "...
Characters who survived the snap.
It's worth noting that the original "Avengers" group — Tony Stark, the Hulk, Thor, Captain America, Hawkeye, and Black Widow all survived. Trailers have shown Hawkeye donning his new Ronin outfit.
