Tony and Peter are the central figures in 'tony replaces peter fanfiction'. However, depending on the context of the fanfiction, other characters from the Marvel universe could be involved. For instance, if it's set in a school environment, Ned Leeds might be there. He would be confused and maybe a bit sad about Peter being replaced by Tony. And then there could be the Avengers, who would have to adapt to this change as well, with characters like Steve Rogers having his own thoughts on whether Tony is the right replacement for Peter.
Obviously, Tony and Peter are the main characters. Tony, with his genius intellect and wealth, and Peter, the young and spry superhero. There could also be other characters like Pepper Potts who might be involved in the story, perhaps trying to mediate between Tony and Peter or having an opinion on Tony replacing Peter.
Obviously, Harley would be one of the main characters as she is replacing Peter. And characters like Aunt May could still be in the story. She might be a bit confused at first about this new person in Peter's place.
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.
Obviously, Tony Stark and Peter Parker are the main characters. Tony is the one making Peter his heir, so he'll be a central figure in guiding Peter and setting things up for him.
Well, one possibility is that Tony could replace Peter in a mission. Maybe Peter gets injured and Tony steps in to finish what Peter started. It could also be about Tony taking over Peter's role in a social or school setting within the fanfiction world.
I think Rhodey would be a likely character. He was Tony's close friend, so he would be involved in verifying Peter's claim and guiding him. Also, Aunt May could play an important role. She has raised Peter and now has to come to terms with his new identity. And there could be some other Avengers like Natasha or Clint who knew Tony well and could offer their perspectives on this new family revelation.
Pepper Potts might appear. She could play a role in helping Tony take care of Peter, like making sure he has a proper diet and a comfortable living space in the Stark Tower. She might also be a maternal figure to Peter, giving him advice on relationships and growing up.
If the fanfiction has a more magical or fantasy element, it could be the magical creatures or spirits that Davis was associated with. Sakura Motomiya, when she replaces him, would start interacting with these beings. For instance, if Davis had a special bond with a certain forest spirit, Sakura would now have to build her own relationship with it. Her different personality might make the spirit react differently, either being more friendly or more cautious towards her.
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.
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.
