One common plotline could be time - travel. Maybe a character goes back in time and changes something that makes Peggy Carter become Tony Stark's mother instead of Maria Stark. Another could be some sort of alternate universe where the rules of genetics and family are different.
In some fanfictions, the plot might revolve around a prophecy or a pre - determined fate that Peggy Carter must be the mother of a great inventor like Tony Stark. So, events are manipulated in the story to make that happen. There could also be a plot where an enemy tries to change history to make Peggy Carter Tony's mom as part of a devious plan, but the heroes have to stop it and restore the original timeline. And sometimes, it's just a simple 'what - if' scenario where the author explores how different Tony's life would be if Peggy was his mom without any complex overarching plot.
In some fanfictions, there could be creative interpretations where Peggy Carter is somehow related to being Tony Stark's mom. However, in the official Marvel canon, Howard Stark is Tony's father and Maria Stark is his mother.
He would be more disciplined. Peggy Carter was a no - nonsense person, so Tony would likely grow up with a strong sense of order and responsibility. He might not be as reckless as he was in the original story. His genius would still be there, but it would be channeled in a more focused way, perhaps towards more strategic and patriotic inventions rather than just for the sake of innovation.
If Tony Stark were raised by Peggy Carter in fanfiction, it could drastically change the MCU timeline. For starters, Tony's personality might be different. Peggy was a strong - willed and disciplined person. Growing up under her influence, Tony might be more by - the - book and less of a maverick. His approach to technology could also be different. He might focus more on military applications that align with Peggy's values rather than the more commercial and sometimes unethical applications he pursued in the original timeline. Also, his relationship with Howard Stark would be complex. Instead of the distant and often troubled relationship they had, it could be one of mentorship from Peggy's perspective, with Howard having a different role in Tony's life.
One common plotline is Tony struggling to control his new god - like powers. He might accidentally cause damage or endanger his friends while trying to figure out how to use them properly.
A less obvious but still common theme is the exploration of different cultures. Sometimes the OC comes from a different background, and the story explores how that culture interacts with Peggy's world. This can lead to some really interesting storylines, like how different values and traditions play a role in solving problems or in the characters' relationships.
Tony Stark was not one to be overly sentimental, but Aunt Peggy's funeral was different. As he entered the church, memories of the old tales of Peggy Carter flooded his mind. He remembered her as a symbol of strength and resilience. During the service, he couldn't help but think about how she was part of a generation that had laid the foundation for his own heroics. He knew that her legacy would continue to inspire him in his battles against evil.
I'm not sure if there is a specific fanfiction with that exact premise. There are countless fanfictions out there, so it's possible but not widely known to me.
In this fanfiction, Tony at Peggy's funeral could be a moment of self - discovery for him. He might be surrounded by the reminders of a bygone era. As he stands there, he could be thinking about how Peggy's life and values are still relevant. He may even have an internal dialogue about how he can incorporate some of those values into his own actions moving forward. There could also be some tension if there are people at the funeral who don't quite trust Stark, and he has to deal with that while still showing his respect for Peggy.
Tony Stark could be involved in Aunt Peggy's funeral as a guest paying his respects. He might have heard stories about her from Steve Rogers and felt a sense of admiration for her. So he comes to the funeral to honor her and the legacy she left behind.
Another theme is the bridging of generations. Since they are from different eras, fanfictions explore how they can connect across that time gap. It could be through shared values like patriotism or a love for innovation. This is seen in stories where they work together on projects that combine old - school thinking with modern technology.
