I think Thor could be really excited too. Thor loves a good warrior and Peter, with his spider - like abilities, would be an interesting addition to his view of heroes. Thor might be amused by Peter's small - scale heroics compared to his own grand battles and would enjoy seeing Peter's potential grow.
One scenario could be that the Avengers are facing a new threat that requires Peter's special skills. His ability to stick to walls and his enhanced strength could be crucial. Peter might also introduce a sense of youthful enthusiasm to the group. He could crack jokes during tense situations, which at first annoys some of the Avengers but later they come to appreciate it as a way to lighten the mood.
In addition to the obvious ones, sometimes other characters like Happy Hogan or Pepper Potts might also make an appearance. Happy could be the one who arranges some of Peter's meetings with the Avengers. Pepper might be involved in providing resources for Peter's new tech or helping Iron Man manage his relationship with Peter. But the core always remains Peter Parker and the Avengers.
In some fanfictions, Peter Parker might introduce his homemade tech to the Avengers. He shows them his web - shooters and explains how he created them, which could lead to some cool collaborations where the Avengers help him upgrade his gear. Also, there could be a story where Peter's sense of humor really lightens up the usually serious Avengers. He cracks jokes during a mission and at first the Avengers are a bit taken aback but then start to enjoy his company more.
Well, in such a fanfiction, the Rogue Avengers might initially be suspicious of Peter Parker. They could mistake him for an enemy or a spy at first. But then, as they get to know him, they might see his potential and start to train him in their own unique ways. Maybe they'll share their different experiences from being on the run, which could be really eye - opening for Peter.
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.
One common theme is mentorship. Usually, the more experienced Avengers like Tony Stark or Captain America take Peter under their wing. For example, in many fics, Tony helps Peter upgrade his suit and teaches him about being a hero in the big leagues.
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.
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.
In a 'rogue avengers meet peter parker fanfic', there could be a lot of interesting scenarios. Maybe the rogue avengers need Peter's help for a secret mission. They might initially be skeptical of the young hero but soon realize his potential.
