The Avengers would initially be in shock when they find out Peter is sick. Clint Barton would be the one to keep a calm head and start organizing things. Wanda Maximoff would try to use her powers to ease Peter's pain if possible. Vision would use his vast knowledge to try and find a solution. They would all be very concerned and do everything they can to make Peter better, from getting the best medical help to providing a safe and comfortable environment for him to recover.
Iron Man, on the other hand, might be more direct. He could use his technology to track Peter's actions and confront him. He might threaten to expose Peter's identity if he doesn't stop. And Thor would probably be angry at first. He values his fans a great deal and seeing Peter bully them would make him want to use his hammer to teach Peter a lesson, but then he would also try to understand the situation.
Perhaps Peter's sickness is a result of his overuse of his powers. The Avengers, especially Tony Stark, feel responsible. They start by quarantining Peter in the Avengers Tower. Then, they call in all their medical and scientific resources. They might discover that the only way to heal him is for Peter to temporarily give up his powers, which would be a huge struggle for him.
Yes, there are quite a few. You can start by looking on fanfic platforms like Archive of Our Own. Just search for 'Avengers Peter Parker sick' and you'll likely find a variety of stories. Some might focus on Peter getting sick during a mission and how the Avengers take care of him, while others could be about him getting sick and having to deal with it while hiding his identity.
Some Avengers might be initially skeptical. Thor, for example, might not understand the power of a 'spider - boy' at first. But others like Captain America would probably see his potential and welcome him. Black Widow might be intrigued by his skills and try to train him further in espionage - related aspects.
Peter could rely on his own inner strength. He has a strong moral compass, so he might use that to remind himself that the Avengers' actions are wrong, not his. And then he could focus on using his Spider - Man skills to prove his innocence or protect himself.
Well, in this fanfiction, Peter Parker might meet the Avengers in a more casual setting. For example, he could be at a science expo where some of the Avengers are also present. Peter is there to show off his latest web - shooter design. The Avengers notice his intelligence and his unique abilities as Spider - Man. They then start a conversation with him, and from there, a relationship between Peter and the Avengers begins to form. This could lead to Peter getting involved in more Avengers - level missions and growing as a hero.
Tony Stark might use his quick wit and technology. He could immediately scan Peter to make sure there's no physical danger causing the hyperventilation. Then he'd probably crack a joke to try and calm Peter down, like 'Kid, you breathe any faster and you'll fly away like a human jetpack.'
Peter Parker's time at Avengers Tower in fanfiction could be filled with a mix of excitement and self - discovery. He might be invited to a big Avengers party at the Tower and feel out of place at first. However, as the night goes on, he starts to relax and shows off his unique skills, like his acrobatic fighting style. He could also meet some new allies or even potential love interests among the people associated with the Tower.
One great 'Peter Parker and Avengers' fanfiction is 'The Young Avenger's Mentor'. In this story, Peter Parker uses his street - smart skills and scientific knowledge to help the Avengers in a unique way. It shows his growth from a local hero to a key member of the Avengers team.
Another possibility is that Peter Parker's soulmate is Natasha Romanoff. She could act as a mentor to him in addition to being his soulmate. Natasha's combat skills and experience would complement Peter's abilities well. They might share a bond that goes beyond the typical superhero relationships, perhaps a connection based on their shared sense of loyalty and duty.
