Iron Man would probably be the most interested. He's always into new technology and Spider - Man's web - shooters would be something he'd love to study and maybe even improve.
I think Peter has a certain charm that would appeal to Thor. Thor, being from a different world himself, might find Peter's fish - out - of - water experiences in Europe quite relatable. He'd be interested in seeing how Peter deals with the new challenges, especially the ones that are different from the battles in New York. Also, Thor loves a good adventure, and Peter's movie is full of that.
Another possibility is that the Avengers are being manipulated by a villain. The bad guy could be using false information to make the Avengers believe that Spider - Man is a danger. So they go after him without really knowing the truth.
Well, maybe he's got some secret mission that he doesn't want the Avengers to interfere with. You know, like protecting a particular person or some crucial information that he thinks the Avengers might mess up if they get involved.
Yes, there might be such fanfiction out there in the vast world of fan - created content. However, this kind of plot is quite dark and not in line with the typical heroic and collaborative image of the Avengers and Spider - Man in the mainstream comics and movies.
It's highly unlikely that the Avengers, as fictional characters in their own right within the Marvel universe, would actually sit down and read Spider - Man fanfiction. They are usually too busy saving the world or dealing with their own personal dramas. Fanfiction is more of a concept for the fans in the real world.
Well, in the official Marvel lore, we don't see the Avengers sitting around reading Spider - Man fanfiction. But if we think about it in a more fun, what - if way, characters like Natasha Romanoff might read it to better understand the public perception of Spider - Man. Since she's good at gathering intelligence and understanding people, she could use fanfiction as a way to gauge how the general public, especially the fans, view the friendly neighborhood Spider - Man. And who knows, maybe Peter Parker himself would be horrified or flattered to know that some of the Avengers might be reading fan - created stories about him.
Captain America could be his best partner. Cap has great leadership skills and a strong moral compass. He could teach Spider - Man a lot about being a hero in terms of responsibility and making the right decisions. Also, Spider - Man's acrobatic fighting style would complement Cap's more straightforward combat approach.
Spider - Man would probably be defensive at first. He's used to working alone most of the time, and being interrogated by the Avengers would seem unfair to him. He might crack some jokes to ease the tension, but also firmly state that he's a hero too.
Spider - Man would likely be confused at first. He respects the Avengers and can't understand why they are suddenly after him. He might try to talk to them, to explain that he's innocent. For example, he could swing up to Captain America and start pleading his case.
Spider - Man would be very confused. He would feel betrayed because he thought the Avengers were heroes he could trust. He could start by asking them why they are doing this. If they don't give him a satisfactory answer, he might try to escape in a sneaky way, using his spider - like abilities to find a weakness in their capture setup while still trying to reason with them.
