When the Avengers read Peter Parker fanfiction for the first time, it's a mixed bag. Natasha would be observant, looking for how the writers depict Peter's character growth. Is it in line with what she knows of him? Thor would find it novel. He'd be like a child with a new toy, enjoying the different takes on Peter. Bruce might be a bit hesitant, not sure if he should be taking it seriously or not. But overall, they'd all be somewhat intrigued by this new form of storytelling about their young friend.
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.
Some Avengers might enjoy it. Iron Man, being the tech - savvy and open - minded one, could be interested in seeing how fans imagine his next inventions or his relationships with other heroes. He might even get some inspiration from the creative ideas in the fanfiction. But then there are Avengers like Thor who might be more confused than entertained. He might not understand the modern writing styles and some of the outlandish ideas in the fanfictions.
Some would be entertained. For instance, Thor would probably enjoy the grandeur that fans might add to the Iron Man 3 story. He loves big, epic tales. Hawkeye might see it as a light - hearted read during his downtime.
Probably Steve Rogers. He has that all - American hero charm and he values loyalty and courage, which Peter clearly has. Steve would recognize those qualities in Peter right away and would want to get to know him better. He might see Peter as a symbol of the future of heroism and be eager to befriend him.
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.
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.
The Avengers might have a range of reactions. Tony Stark would probably be amused and might make some sarcastic comments about how the fanfiction portrays Peter. Steve Rogers would be a bit more confused at first, not fully understanding the concept but then find the positive portrayals of Peter endearing. Thor would likely think it's a strange Midgardian thing but be entertained by the stories that show Peter as a heroic figure.
Peter Parker's spider - sense and super strength, along with Spider Gwen's acrobatic skills and wall - crawling ability, would add a new dimension to the Avengers' combat capabilities. Their agility could help in quickly evading attacks and getting to hard - to - reach places during battles.
They could meet at a scientific conference. Peter, being a science - minded guy, would be there to learn about the latest advancements. Shuri, representing Wakanda, would be there to showcase some of Wakanda's incredible technology. Their eyes might meet across the room, and Peter, being the friendly type, would go over to introduce himself. And that's how their first encounter could start.
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.
