Peter is bound to be a central figure. But among the Avengers, Iron Man might play a really big role. He could be the one who discovers Peter or is most interested in his abilities. Also, Captain America might be important as he represents the more traditional heroic values and could have an interesting dynamic with Peter, who is a new - age hero.
Peter is the key character from his side. For the Avengers, Thor could also be a major character. Imagine Peter's reaction to Thor's godly powers. And Black Widow could be there to test Peter's combat skills and espionage knowledge. Hulk might be involved in a situation where Peter has to calm him down or use his agility to avoid the Hulk's rampages.
Obviously, Peter (presumably Peter Parker, Spider - Man) would be one of the main characters. And of course, the Avengers members like Iron Man, Captain America, Thor, Hulk, Black Widow, and Hawkeye are likely to be main characters too as they are the ones 'meeting' 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.
Obviously, Rhodey and the Avengers members like Iron Man, Captain America, Thor, Hulk, etc. would be the main characters.
The main characters are Peter and the Avengers. But we might also see some side characters like Happy Hogan who could be involved in some way. Maybe he's the one who arranges the initial meeting between Peter and the Avengers. And Pepper Potts could also make an appearance, giving her take on Peter's presence in the Avengers' world.
Well, obviously Peter Parker (Spider - Man) is one of the main characters since the story is about rescuing him. Then, of course, the Avengers. This would include Iron Man (Tony Stark), who would likely use his high - tech gadgets and suits to help in the rescue. Captain America (Steve Rogers) would bring his leadership and combat skills. Thor with his godly powers would also be a key figure, and Hulk (Bruce Banner) could provide brute force when needed.
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.
Captain America and Peter would also have great interactions. Steve Rogers could teach Peter about the importance of responsibility and leadership. And Peter, with his youthful enthusiasm, could remind Steve of the good in the world and the future.
The main characters could also be some villains. They might target Peter's sister to get to Spider - Man. So, villains like Vulture or Mysterio could be in the story, which would then force the Avengers to step up and protect her. In this case, the dynamic between the good guys (Avengers and Peter's sister) and the bad guys would be the central focus of the fanfiction.
Obviously, Peter Parker, also known as Spider - Man, is a main character. Then there are the Avengers like Tony Stark, Captain America, Thor, Black Widow, and Hulk. They often play important roles in the fanfiction, either as Peter's mentors, teammates, or sometimes even as antagonists in certain plotlines where there are misunderstandings or conflicts.
The main characters are definitely the two Peters. However, other supporting characters are likely to include Pepper Potts who could offer some non - combat help to the Peters, like providing resources or shelter. And then there's Spider - Man's friends from his own universe like Ned Leeds or MJ. In the Avengers side, Thor could be involved in some way, perhaps using his Asgardian knowledge to help the Peters understand the multiverse concept better.
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.
