On the other hand, it could also be a turning point for the better. Sometimes a big outburst like that can clear the air. They might realize they've been misunderstanding each other and start to work on their relationship more effectively after the initial shock of the yelling.
One possible reason could be a disagreement over superhero tactics. Peter, being young and idealistic, might yell at Tony if he thought Tony's methods were too extreme or not in line with his own sense of justice. For example, if Tony made a decision during a battle that put civilians at risk, Peter would likely be very vocal about it.
The relationship can start out a bit rocky in some fanfictions. Tony may be initially dismissive of Peter as just a kid. But as Peter shows his capabilities, Tony starts to take him more seriously. They then start to bond over their love for science and technology. Peter is eager to learn from Tony, and Tony enjoys teaching Peter new things. This mutual exchange helps their relationship grow from a mentor - mentee one to a true friendship.
Maybe Peter misses an important training session. Tony has probably put a lot of effort into training Peter to be a better superhero. If Peter skips out on training for something unimportant, like going to a party or just being lazy, Tony would be justifiably angry and yell at him for not taking his superhero responsibilities seriously.
In fanfiction, the relationship between Tony Stark and Peter Parker is often explored in many ways. It can be a mentor - mentee relationship, where Tony imparts his knowledge and wisdom to Peter. For example, in some stories, Tony helps Peter upgrade his suit, teaching him about new technologies. This relationship also has a strong emotional bond, with Tony seeing Peter as a sort of surrogate son or a younger version of himself, full of potential and in need of guidance.
In many fanfictions, Tony Stark might comfort Peter Parker by giving him words of wisdom. For example, he could say things like 'Kid, everyone makes mistakes, and it's how we learn from them that matters.' This simple yet profound advice can make Peter feel better about his own blunders.
Another reason could be related to Peter's mistakes. He may make errors during a mission that put the whole team or the city at risk. Tony, who has a lot of responsibility on his shoulders, might yell at Peter as a way to make him understand the seriousness of his actions and to prevent future mistakes.
Well, in a lot of these fanfictions, it's about trust building. At first, Peter is in awe of Tony Stark, the famous billionaire and superhero. Tony, on the other hand, is initially a bit hesitant but soon realizes Peter's pure heart. They start to train together, and Tony shares his technological secrets with Peter. This exchange of knowledge and skills is like a father passing on his legacy to his son. And as they go through tough times, like when Peter makes mistakes or when they face powerful enemies, their relationship evolves into a very deep and emotional father - son connection.
Peter might be initially shocked and a bit scared. After all, Tony is like a mentor to him. But then he could become defensive, trying to explain his actions or point of view.
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.
At first, it's a bit rocky. Peter is used to being on his own, and Tony has his own way of doing things. But as they spend more time together, they find common ground. Tony helps Peter with his schoolwork, especially in science - related subjects. Peter, in turn, shows Tony the importance of having a pure heart in the superhero world. They go through challenges together, like fighting villains side by side, which deepens their bond.
