It could be Scott Lang. Scott is a bit of an underdog himself and he has a fun - loving nature. He would be drawn to Peter's youthfulness and enthusiasm. Plus, Peter's powers are so unique that Scott would be curious about them and that curiosity could lead to a fast friendship.
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.
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.
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.
There's a possibility that it's an old enemy of the Avengers who sees this as an opportunity. For example, Hydra could be involved. They might try to manipulate the situation to bring down both the rogue avengers and Peter Parker. They could spread false information to make the public turn against them all, while they carry out their own evil plans in the shadows.
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.
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.
Obviously, Peter Parker himself is a key character. His naivete and enthusiasm for heroism would be a big part of the story. Then there's Captain America from the Rogue Avengers. He would likely be the moral compass of the group. And Black Widow, with her skills in espionage and combat, could also be important in strategizing against any threats they face.
Maybe Thor. Peter has never seen someone as powerful as Thor with his hammer and god - like abilities. Thor's larger - than - life presence could be really fascinating for Peter.
Obviously, baby Peter would be one of the main characters. Among the rogue Avengers, it could be Captain America if he goes rogue in the story. Hawkeye might also be there as he has a family - like side and could be sympathetic to baby Peter. And Scarlet Witch could be involved too, with her powerful magic.
The Green Goblin is a likely kidnapper. He's always had a vendetta against Spider - Man. Also, Doctor Octopus could be a candidate. His mechanical arms and his intelligence make him a formidable foe who might kidnap Peter for his own devious experiments. Another one could be the Vulture, who might see Peter as a valuable asset to sell to the highest bidder in the criminal underworld.
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.
