It could be Tony Stark. Since Peter is a brilliant kid and Tony is a genius, they might have a special bond. Tony could see a younger version of himself in Peter and take him under his wing. Their connection could be deeper than just mentorship, like they have a soul - to - soul understanding.
Maybe Captain America. Steve Rogers values loyalty and courage, and Peter has plenty of that. They could form a close connection as Steve sees in Peter the future of the Avengers. Peter would look up to Steve as a symbol of heroism, and they could be the ones who always have each other's backs during battles and tough decisions.
One option is Pepper Potts. She is intelligent and has a strong will. In a fanfiction, she might see the potential in Peter and they could develop a relationship. Pepper could also help Peter deal with the business side of being a superhero, like Tony Stark did, and they could fall in love over time.
Well, one possible plot could be that Peter has some sort of special connection with each of the Avengers. Maybe he has a unique power that only activates when he's near them, and they gradually realize he's like a missing piece to their team. They start to protect him and he in turn helps them with his intelligence and quick thinking.
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.
Maybe Captain America. Captain America values honor and loyalty, and Rhodey with his military background would share those values. They could bond over their sense of duty. Rhodey might look up to Captain America as a symbol of leadership, and Captain America would respect Rhodey's skills and experience. So Captain America could be his closest ally in the story.
One way is by getting involved in Peter's school life in a more official capacity. Maybe they could arrange for some anti - bullying seminars at the school. Natasha could also train Peter in stealth and evasion techniques so that he can avoid the bullies more easily. Thor could even offer to be Peter's bodyguard for a while, at least until the bullying situation is resolved.
The three Avengers could be Iron Man, Captain America and Thor. Iron Man could provide the high - tech gadgets and strategic thinking. Captain America would bring leadership and his combat skills. Thor with his godly powers like lightning and super strength would be a great addition. They would each have different interactions with Spiderman, for example, Iron Man might be like a mentor to him, while Thor could be more of a friendly rival in terms of strength.
If Peter was adopted by the Avengers, his relationship with Wanda Maximoff could be quite special. Wanda could help Peter understand and control his emotions better, especially when he's under stress during battles. Peter could also befriend Vision, and together they could explore the boundaries of science and magic. The Avengers would start to see Peter as a full - fledged member of the family. They would be more protective of him, and Peter would feel a stronger sense of belonging. His relationships would no longer be just about superhero partnerships but would be about real family connections. For example, they would celebrate holidays together and have family - style dinners, which would strengthen their bonds even more.
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.
It could be Mysterio. He's known for his illusions and deception. He might create false scenarios that make the Avengers think Peter is a threat. He could manipulate the Avengers' perception of Peter's actions, like making it seem like Peter is causing destruction when he's actually trying to help.
I think it could be Clint. He has a family and the thought of his family being Snapped away would be devastating. He would be haunted by the idea that he wasn't there to protect them. He might feel a great sense of guilt and loss compared to the others.
