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.
Well, they might be really impressed with how Spider - Man has developed in this fanfiction. Maybe they'll cheer for his new moves or be shocked at the new villains he faces.
Well, in the official Marvel universe, there's no indication that they do. Fanfiction is more of a meta - concept created by fans outside the official canon. However, it could be an interesting idea for a crossover fan - made story where the Avengers stumble upon some TASM fanfiction, maybe as part of a light - hearted moment in a team - building exercise or something.
Tony would probably focus on the tech aspects. He might think Spider - Man's web - shooters could be upgraded in a certain way. Steve would look at the hero's values, seeing if he's staying true to what a hero should be.
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.
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.
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 probably be shocked at first. He looks up to the Avengers and being kidnapped by them would be the last thing he expects. He'd likely try to talk his way out, using his quick wit and charm. He might start by asking why they're doing this and try to convince them that they've made a mistake.
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.
