He would be very hurt. He might isolate himself for a while, doubting his own judgment in trusting his friends. Spider - Man might also start to question his identity as a hero. After all, if his friends can turn on him, what does that say about his relationships and his role in the world?
Spider - Man's reaction could be complex. He would be devastated, of course. But he's also a hero with a strong sense of justice. He might try to investigate the situation further to find out if there were external factors influencing his friends' actions. He could also feel a sense of guilt, wondering if he had done something to make them turn against him. However, he wouldn't let this break him completely. Instead, he would channel his emotions into his superhero duties, while still holding out hope that his friends could be redeemed.
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 fanfiction often showcases the creativity of the fans. For instance, there are fanfictions that put Spider - Man in crossovers with other superheroes or even in different historical settings. I think it's a great way for fans to express their love for the character and expand on the Spider - Man universe that we know from the comics and movies.
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.
Sakura might find it a bit odd at first. She'd probably tease Naruto a little about it, but then she'd see how passionate he is and just let him be. Shikamaru, on the other hand, would be like 'too troublesome' but secretly be a bit interested. Choji would probably just laugh it off and ask Naruto if he could share some of his Spider - Man comics if he had any.
It could be his mentor. In the fanfic, the mentor might think that Spider Man is becoming too powerful and is a threat to the balance of power. So, he could betray Spider Man by leaking his secret identity or setting him up to be captured by the authorities.
It all starts when Peter Parker gets bitten by a radioactive spider. This gives him amazing powers like super strength, the ability to climb walls, and a 'spider sense'.
Even one of Spider - Man's fellow superhero friends might betray him. Maybe they get jealous of Spider - Man's popularity or feel that he is getting all the credit for their team's successes. This internal betrayal would add a lot of drama and conflict to the fanfiction story.
It expands the universe by introducing new characters. Fanfiction writers can create their own original characters that interact with Spider - Man. These characters could be other superheroes, villains, or just normal people who get caught up in Spider - Man's world. For example, a new hero who teams up with Spider - Man to fight a common enemy.
