One common theme is the generation gap. Tony is more experienced and sometimes sees Peter as naive, leading to conflicts. For example, in many fanfictions, they fight over how to approach a villain, with Tony wanting a more calculated approach and Peter being more impulsive.
Betrayal is another theme. Maybe Tony makes a decision that Peter thinks is against the greater good, like in some fanfictions where Tony has a secret deal with a shady organization. This causes a huge fight between them as Peter feels let down.
The themes of good vs evil and self - discovery are also quite common. Peter and Tony represent the good side against Beck's evil. And during the fight, both Peter and Tony often discover new things about themselves, their capabilities and their relationship with each other. For example, Peter might discover how far he can push his powers, and Tony might realize how much Peter has grown.
A common theme is mentorship. Tony being the experienced one and Peter as the young protege. Another is friendship. They are often depicted as having a really strong bond.
The theme of family is also quite prevalent. Since Peter lost his uncle and Tony has his own family issues, they form a sort of surrogate family. Also, the theme of sacrifice. They are both willing to sacrifice themselves for the greater good, which is often explored in these fanfictions. In many of them, there are detailed descriptions of how they support each other in difficult times, which makes their relationship more complex and interesting. For example, in some stories, when Peter is in trouble at school because of his superhero identity, Tony steps in to help him deal with it. This not only shows their friendship but also how they are there for each other like family.
A common theme is mentorship. Tony often takes on the role of mentor to Peter, teaching him about his powers and responsibilities.
A major theme is growth. Peter's growth as a superhero and as a person under Tony's influence. Technology also plays a role as a theme. Tony's advanced tech and how it helps Peter. And there's the theme of trust. Building and maintaining trust between them, especially when facing tough situations in the fanfiction world.
Another theme is redemption. Sometimes the fight is a way for Bucky to try and redeem himself in Tony's eyes. He might face Tony head - on in the fight, hoping that by taking the punishment or showing his remorse, he can be forgiven.
A common theme is loyalty. Tony's possessiveness often stems from his loyalty to Peter, and vice versa. They are there for each other through thick and thin.
One common theme is mentorship. Tony often takes on the role of a mentor to baby Peter, guiding him in various aspects like academics, using his powers, and moral values. Another theme is protection. Since Peter is a baby or very young in these fictions, Tony is usually very protective of him.
One common theme could be misunderstanding. Maybe there's a miscommunication between Tony and Peter that leads to Tony ignoring him.
Comfort is also a big theme. Peter is a young hero facing a lot of challenges. When he's scared or sad, Tony's hug provides comfort. In some fanfictions, Peter has nightmares, and Tony hugs him to calm him down, showing that the hug is a source of emotional support.
