Peter Parker is the central figure, of course. But Hawkeye from the Rogue Avengers could be a significant character too. He might teach Peter some new archery - related skills or tricks. Also, Scarlet Witch could play a major role. Her powers are so unpredictable and powerful that she could be a game - changer in any battles or challenges they encounter. And don't forget Ant - Man, who could use his size - changing abilities in really creative ways to help the group out of tight spots.
In this fanfiction, Peter Parker is the main thread that ties everything together. However, the Rogue Avengers members like Falcon are likely to be important. His aerial skills could be crucial in transportation and scouting. Loki, if he's part of the Rogue Avengers in this story, would add an element of mischief and unpredictability. He might create some internal conflicts within the group, which Peter would have to help resolve. And Thor, with his godly powers, would be a force to be reckoned with in any confrontations, and Peter could learn a lot from his warrior spirit.
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.
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.
In this fanfiction, Peter Parker might initially be in awe of the Rogue Avengers. He could try to prove himself to them, showing off his Spidey skills. Maybe they start off distrusting him, seeing him as just a kid, but as they face challenges together, they come to respect his abilities and his big heart.
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 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.
In this fanfiction, Penny Parker would surely interact with Thor. Thor could share his stories of Asgard with her, and Penny might be in awe of his godly powers. Also, Hulk could be an interesting character for her to meet. Maybe she'd try to find a way to calm the Hulk down when he gets angry. And Black Widow would be another key character. Black Widow could train Penny in espionage and hand - to - hand combat skills.
Peter Parker is the main focus, of course. His parents are central as well. Depending on the fanfiction, villains could also be important characters. If Peter's parents have some sort of unfinished business with a villain, it could lead to a big showdown. And don't forget Aunt May. She could provide some emotional support and wisdom as Peter goes through this strange encounter with his parents.
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.
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.
The main antagonists could be the official Avengers themselves. Since Peter Parker has joined the rogue Avengers, the main Avengers group might see them as a threat to the order they are trying to maintain. They could try to stop the rogue Avengers from achieving their goals, which would put them in direct conflict with Peter and his new allies.
There could also be new characters created specifically for the fanfiction. Maybe a new love interest for one of the Peters, or a sidekick that is unique to this particular fan - made story. This new character could bring a fresh dynamic to the relationship between the two Peters.
