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.
Definitely baby Peter. For the rogue Avengers, I can see Winter Soldier being part of it. He has his own complex past and his presence would add an interesting dynamic. Black Widow might also be there. She's used to handling difficult situations and could play a role in protecting baby Peter. And then there's Ant - Man, who could provide some comic relief while also being a useful member in any situation they face.
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.
In this fanfiction, perhaps the rogue Avengers are hiding out when they hear baby Peter crying. They initially think it's a trap but then realize it's just an innocent baby. Some of the Avengers might want to take him with them because they see his potential, while others are more hesitant due to their own precarious situation.
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.
It could be Hydra. They might be trying to take advantage of the split between the Avengers and the Rogue Avengers. They see Peter as a wild card and try to either capture or turn him against both groups.
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.
In such a fanfiction, the Rogue Avengers might initially be suspicious of Peter. They could test his loyalty and skills. Maybe Peter has to prove himself worthy to join their cause against the establishment Avengers. For example, he could show off his spider - powers in a unique way that impresses them.
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.
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.
