One possible reason could be their different priorities. Tony is often consumed by his work on new inventions and protecting the world as Iron Man. Pepper, on the other hand, may desire a more stable and normal life. In some fanfictions, she might feel neglected because Tony is always in the lab or off on some dangerous mission. Another factor could be external threats. Enemies might target Pepper to get to Tony, which could put a strain on their relationship as Tony constantly has to worry about her safety and she may grow tired of living in fear.
In fanfiction, miscommunication can play a big part in their break - up. Maybe Tony fails to communicate his true feelings about their future together. For example, he might assume Pepper knows he wants to settle down someday, but he never actually says it. Pepper could interpret his lack of clear communication as a lack of commitment. Also, the public attention on their relationship could be overwhelming. Paparazzi and public expectations might create stress that they can't handle, leading to their break - up.
Often, it shows a great deal of sadness. Tony might be depicted as feeling lost without Pepper. He could become even more withdrawn into his work as a way to cope, but still be constantly haunted by memories of her. For Pepper, she might feel a mix of anger and heartbreak. Anger at Tony for not being able to be the man she needed, and heartbreak because she truly loved him.
In this fanfiction concept, it could bring a whole new dynamic to the Marvel universe. Peter being their son would mean he has a very different upbringing. He might inherit Tony's genius and Pepper's business acumen. There could be stories about him growing up in the Stark mansion, having access to all of Tony's technology from a young age. And perhaps he'd be trained by Tony in both technology and self - defense much earlier, leading to a Peter who is even more formidable than in the original storylines.
In these fanfictions, their relationship is explored through the shared responsibilities. Tony might take on more domestic tasks like making sure Pepper has a healthy diet. They also communicate more deeply. They discuss their hopes and fears for the child. This could lead to them resolving some past issues in their relationship. For instance, if there were any trust issues before, the pregnancy could be a time to rebuild that trust.
It could be that Peter was in a hurry and didn't have time to talk. He might have been in the middle of something important in his own life, like dealing with school or helping a friend, and just had to end the call abruptly.
One reason could be a misunderstanding. Maybe Mal overheard something Ben said that she misinterpreted. For example, if he was talking about some political decision for Auradon that she thought was about her personally.
In this fanfiction, Pepper might struggle a bit with the idea of being pregnant while Tony is constantly in the spotlight as Iron Man. She could worry about how their child will grow up in such a public environment. However, Tony reassures her that they can create a normal family life within their extraordinary circumstances.
There could be. Fanfiction is a vast world full of various creative ideas. Writers might be attracted to the idea of Tony and Pepper being Peter's parents as it can bring new storylines, such as how they would raise Peter in the Stark household, with all the technology and wealth at their disposal. It could also explore how Peter's powers would be incorporated into their family dynamic.
Creative differences mainly led to their break - up.
In these fanfictions, Pepper's character often develops into a more assertive and heroic figure. She starts off as Tony's assistant, but as she saves him, she gains confidence. For example, she might become more fearless in the face of danger. She may also develop new skills, like combat skills if she has to fight off those who are threatening Tony. Her relationship with Tony also deepens, becoming more of an equal partnership rather than just an employer - employee relationship.
One common theme is the anticipation of parenthood. Tony might be shown as both excited and nervous about becoming a father. He could be constantly thinking about how to keep Pepper and the baby safe, especially considering his dangerous lifestyle as Iron Man.
