For Tony Stark, it could be a blow to his ego. He might see Peter's departure as a sign of failure in his mentorship. He could also start to question his own actions and decisions that led to Peter leaving.
One possible reason could be a difference in ideology. Maybe Peter Parker feels that Stark's methods are too extreme or not in line with his own moral compass. For example, Stark might be involved in some projects that Peter doesn't agree with, such as using certain unethical technologies in the pursuit of justice.
There are a great number of fanfictions where Tony Stark is Peter Parker's father. This is because their relationship in the official Marvel universe is already somewhat of a mentor - mentee one. Fanfiction writers take it a step further. For example, in some stories, Tony discovers he has a biological connection to Peter. In others, it's more of an emotional father - son bond that develops over time through shared experiences, like fighting villains together or working on new tech in the Stark labs.
Perhaps in a time of crisis for Stark Industries, Peter Parker stepped in and saved the company. His intelligence and unique abilities, combined with his good heart, made the board of directors decide to transfer the ownership to him.
There could also be other characters like Happy Hogan. He might play a role in helping Tony take care of Peter, like driving him to school or keeping an eye on him when Tony is busy. And perhaps Aunt May could still be in the picture, adding an interesting layer to the story as she and Tony interact regarding Peter's upbringing.
In some fanfictions, Tony Stark is indeed portrayed as a father figure to Peter Parker. Writers often explore this relationship to add depth and a different dynamic to the characters. It can be a very interesting take as Tony can offer guidance, resources, and protection to Peter, much like a father would.
Peter might focus more on using Stark Industries' resources for the benefit of the community. He could start projects that aim to improve the living conditions in poor areas, like creating advanced and affordable housing technology.
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.
One aspect of such fanfictions could be the way it challenges the traditional gender roles in superhero stories. Since male pregnancy is not a common concept in the original superhero lore, it can lead to interesting plot twists. For example, it might change the way they approach their superhero duties while also dealing with the physical and emotional changes that come with pregnancy.
One possible scenario in such a fanfiction could be that Peter is crying because he misses Tony Stark after his death. Tony was like a mentor to Peter, and his absence leaves a huge void. Peter might be in the Avengers compound, looking at old photos or mementos of Tony, and the memories make him break down in tears.
The pairing of Tony Stark and Peter Parker in fanfiction is significant as it combines two very popular characters. Tony represents the experienced, high - tech billionaire superhero, while Peter is the young, enthusiastic, and street - smart Spider - Man. Their combination allows for a lot of character development. For instance, Peter can learn from Tony's mistakes and successes, and Tony can be reminded of his own youth and idealism through Peter.
