Captain America could also be a great parental figure. He has strong moral values and can teach Peter about honor, integrity and the importance of fighting for what's right. He can guide Peter in making the right decisions, especially when it comes to using his powers for good.
Iron Man would be a likely candidate. He's already shown a sort of father - figure - like relationship with Peter in the movies. He can offer Peter high - tech resources, valuable advice on being a superhero, and also teach him about responsibility in a more modern way.
One interesting plotline could be Peter struggling to fit in with the Avengers' high - tech and super - powered world while still maintaining his normal life as a high school student. For example, he might have trouble keeping up with the Avengers' training schedules while also studying for exams.
One possible reason is that Peter's quick rise to popularity among the public might make the Avengers jealous. They've been around for a long time, and suddenly this young kid is getting all the attention.
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.
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.
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.
Thor would be a likely candidate. Since he is Loki's brother, he already has a connection with him. Thor might be the one to convince the other Avengers to give Loki a chance and be the first to reach out and try to befriend him in this new situation.
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.
One possible reason could be a misunderstanding. Maybe Peter accidentally gets involved in something that looks bad to the Avengers, like being in the wrong place at the wrong time during a security breach. So they misjudge him and are mean as a result.
Obviously, Peter Parker is one of the main characters. And then, the Avengers members like Tony Stark, Steve Rogers, Natasha Romanoff, etc. are also main characters as they are the ones adopting Peter. They play important roles in Peter's new life and in the overall story.
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.
