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.
Peter Parker is the central figure in need of rescue. Among the Avengers, Black Widow would be important. She has her stealth and combat abilities which could be crucial in sneaking into places to find Peter. Hawkeye could use his archery skills to cover the team from a distance. Doctor Strange might also be involved, using his magic to locate Peter or deal with any magical threats during the rescue. And, of course, Ant - Man and the Wasp could play roles, perhaps using their size - changing abilities to access hard - to - reach areas where Peter might be held.
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.
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.
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, 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.
Definitely the Avengers members like Captain America, Iron Man, Thor, Hulk etc. would be main characters as they are the core of the Avengers. On the Hydra side, characters like Baron Wolfgang von Strucker could be prominent. Also, there might be some original characters created specifically for the fanfiction, perhaps a Hydra scientist who is behind a new and dangerous experiment targeting the Avengers.
There could also be secondary characters that play important roles. For instance, characters like Vision or Scarlet Witch. Vision's unique powers and his relationship with the other Avengers could add an interesting dynamic. Scarlet Witch's powers are extremely powerful and often unpredictable, so she could be a key figure in any sort of conflict or plot development within the fanfiction. Additionally, new characters created specifically for the fanfiction might also become important, depending on the creativity of the writer.
One interesting plot could be that Peter gets trapped in an alternate dimension, and the Avengers have to figure out the science behind it to rescue him. They might face various challenges like strange creatures and unstable energy fields in that dimension.
Other Avengers might interact with Peter too. For example, Rhodey could befriend Peter and train with him. Or Natasha could teach Peter some spy skills, which could be useful for his superhero activities.
Peter is surely the central character. In addition to the well - known Avengers, there might be other characters too. For instance, Doctor Strange could be involved as he has knowledge about the Stones. Also, villains who are after the Stones might also be considered main characters in a sense as they drive the plot forward. It's all about how Peter and the Avengers interact with these characters in the context of the Stones.
