In fanfiction, why would the Avengers attack Spider - Man?

One reason could be that they suspect him of being involved with a new villain's scheme without having all the facts. So they act preemptively and capture him.

The Avengers might capture Spider - Man if they suspect him of being involved with a new, unknown threat. For example, if there are strange crimes happening in the city and Spider - Man is seen at the scene every time, they could assume he's part of it.

He could be seriously injured. The Avengers are a powerful group, and their combined attack would be hard for Spider - Man to withstand. He might end up with broken bones or other serious physical injuries.

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.

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.

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.

Well, Tony Stark might find it amusing and start making sarcastic comments about how creative the fans are. Steve Rogers would probably be a bit confused at first, but then he'd see the passion in the fanfiction and respect it. Thor would likely think it's a strange Midgardian thing but still be entertained by the wild stories.

The Avengers' reactions would vary. Natasha Romanoff might be intrigued by the different characterizations of Spider - Man in the fanfiction. She'd analyze how the writers are exploring his character. Bruce Banner could be a bit worried if the fanfiction has some scientific inaccuracies related to Spider - Man's powers. Clint Barton might just see it as a fun distraction and not take it too seriously.

Another possibility is that in the fanfiction, Spider - Man's identity was revealed in a way that put the entire Avengers team at risk. The Avengers might then decide to distance themselves from him to protect their own secrecy and safety. This could involve kicking him out of the group to avoid any further potential threats associated with his exposed identity.
