They might be quite surprised. The Avengers are used to their own world and adventures, and seeing a fanfic about Spider - Man would show them a different take on a fellow superhero. Maybe they'd be impressed by the creativity of the fanfic writer in imagining new scenarios for Spider - Man.
If the Avengers watched the 'The Amazing Spider - Man' fanfic, they would likely have a range of reactions. Hulk might not care much at first, but if there's a big action scene in the fanfic, it could catch his attention. Black Widow would probably be looking at the character relationships and how they're developed. Hawkeye might compare the skills of Spider - Man in the fanfic to his own archery skills in a humorous way. And overall, it could be a really interesting experience for them to see how fans view Spider - Man from their own unique perspectives.
If the Avengers watched The Amazing Spider - Man 2 fanfiction, it would be a really interesting scenario. Natasha Romanoff might be intrigued by how Peter balances his normal life and his superhero identity. Bruce Banner could see Peter as a young hero trying to figure things out, much like he was with his own Hulk situation. Clint Barton might be thinking about how to incorporate some of Spider - Man's moves into his own fighting style.
It could strengthen their relationship. If they see positive aspects in the fanfic about Spider - Man, like his heroism and self - sacrifice, they might have more respect for him.
Villains like Green Goblin might be enraged. They might see fanfiction where they are constantly defeated by Spider - Man and feel that their reputation is being sullied. On the other hand, they could also find it amusing in a twisted way, seeing how fans perceive their battles with Spider - Man. And characters like Aunt May would probably be a bit shocked at first by some of the more edgy or modern interpretations in fanfiction, but then she might also be touched by how much fans care about Peter and his story.
Thor could also be a great character to include. His god - like powers and different cultural background compared to Spider - Man would make for an interesting contrast. Imagine Spider - Man being in awe of Thor's hammer and Thor being amused by Spider - Man's web - slinging abilities. They could team up against a powerful enemy, with Thor using his brute strength and Spider - Man using his agility and quick thinking.
They would probably have a range of reactions. Some might be entertained, while others would be more critical. Stark might joke about the science in it not being as good as his own tech.
The Avengers might have a range of reactions. Tony Stark could be amused and might make some sarcastic comments about the plot or the way Spider - Man is portrayed. Steve Rogers might be a bit more traditional in his view, perhaps finding it interesting how the fanfic explores different aspects of Spider - Man's character. Thor could be a bit confused at first but then find the whole idea of a fan - created story quite fascinating.
Well, Tony Stark might be amused and start making sarcastic comments about the plot or the characterizations in the fanfic. He'd probably find some of the more out - there ideas in the fanfic either really cool or just plain ridiculous.
If the Avengers watched Iron Man fanfic, it would be an interesting sight. They would see all kinds of alternate universes and characterizations of Iron Man. Some of the Avengers might be inspired by the creativity of the fans. For example, Rhodey might see new ways to improve Iron Man's suits in the fanfic and think about applying some of those ideas in their real - world (within the MCU) situations. But others like Vision might find it difficult to understand the more emotional and unstructured nature of fanfics as he is used to a more logical view of things.
The Avengers would be very concerned. Captain America would immediately take charge of the situation, trying to keep everyone calm while they assess Spider - Man's injuries. Iron Man would start scanning for the best way to treat him, using his high - tech equipment. Thor might offer some of his Asgardian knowledge of healing, if there was any. Black Widow and Hawkeye would be on guard, making sure there were no further threats while the team focused on Spider - Man.
Maybe Spider - Man discovers a new threat that the Avengers have overlooked. He then tries to convince them of the danger, facing skepticism at first but eventually winning them over with his tenacity and evidence. For example, he could find a hidden group of villains planning to use a new type of technology to take over the world.
