Adding Aunt May to the mix can bring in a whole new level of drama. She loves Peter dearly and might be a bit overprotective. When she realizes the extent of Tony's influence on Peter and the dangerous world of superheroes that Tony is part of, she could have some serious confrontations with Tony. Also, villains like the Vulture can be included not just as the bad guys in action scenes, but also as a source of drama. For example, if the Vulture targets Peter specifically because of his connection to Tony, it adds an extra layer of danger and drama to their father - son relationship.
Nick Fury is an interesting character to include. He might try to use Peter's relationship with Tony for his own S.H.I.E.L.D. purposes. This could put Tony in a difficult position, as he wants to protect Peter but also has to deal with Fury's demands. And then there's Rhodey. He could be jealous of the attention Tony is giving to Peter, thinking that Tony should focus more on their friendship or on Iron Man - related matters. His presence can stir up some internal conflicts within Tony and also create drama between him and Peter.
Pepper Potts could be a great addition. If she's initially hesitant about Tony taking on Peter as a sort of surrogate son, it can create a lot of drama. Maybe she's worried about the danger Peter could bring into their lives. Another good character is Happy Hogan. He could be the voice of reason, sometimes agreeing with Pepper, other times seeing the potential in Peter and siding with Tony. This can lead to some interesting arguments between the characters.
In many Tony and Peter fanfictions, the father - son relationship is often a heartwarming and complex one. Tony, being a mentor - like figure, can be seen as a father figure to Peter. He might guide Peter in his superhero journey, teaching him about using his powers responsibly and also about the harsh realities of the world they live in.
One common theme is mentorship. Tony often takes on the role of teaching Peter about being a superhero, like how to use his powers effectively and make smart decisions in dangerous situations.
One great Peter and Tony father - and - son fanfiction is 'A New Bond'. It beautifully portrays Tony as a mentor and father figure to Peter. The story shows how Tony helps Peter grow not just as a superhero, but also as a young man, dealing with school, relationships, and his newfound powers.
The theme of sacrifice is also present. Tony might sacrifice his own well - being or resources for Peter's sake. And there's the theme of inheritance, like Peter inheriting Tony's technology or his sense of justice.
Another theme is family and belonging. Since Peter doesn't have a father figure in the original story in the same way, fanfictions explore how Tony fills that role and how Peter finds a new family in Tony. It's about creating a sense of home and acceptance between them. For example, in many fanfictions, Tony provides a stable home environment for Peter which he was lacking before.
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.
There could be a plot where Tony's past mistakes come back to haunt him, and he's worried about how it will affect Peter. He might try to distance himself from Peter to protect him, but Peter doesn't understand and feels rejected. This would lead to a rift between them. However, in the end, they would reconcile as they realize how much they mean to each other as father and son.
Often, Peter is really well - written. Writers can capture his naivete and his eagerness to learn and do good. His internal struggle between being a normal kid and a superhero is very engaging.
Peter would likely be in awe of everything and constantly asking Tony questions. Tony, in his father - son role, would patiently answer, with a bit of his usual sarcastic charm. For example, if they see a new piece of tech, Peter would say 'Mr. Stark, how does this work?' and Tony would reply 'Kid, if I told you all my secrets, where would the fun be?'
One great fanfiction could be where Tony Stark takes Peter Parker under his wing more explicitly. He could teach Peter not just about being Spider - Man but also about life in general. For example, they could have heart - to - heart talks about how to deal with the pressures of being a hero and a student at the same time. Tony might share his own experiences of growing up wealthy yet lonely, and how Peter should cherish his family and friends.
