In terms of character relationships, she could have a big impact on Tony's development. Maybe she's the one who convinces him to be more open about his feelings and share his knowledge more freely with the other Avengers. This could lead to a more united Avengers team earlier on in the MCU timeline. Also, her relationship with other characters like Pepper Potts could be really interesting. She might be a confidante for Pepper and offer a different perspective on Tony's actions.
Her existence could also bring in new storylines related to Stark family secrets. There could be some long - hidden family mystery that she discovers, which then leads to a whole new arc in the fanfiction. This mystery could involve something about their father's early experiments or a connection to a powerful and previously unknown organization. All of these things would greatly change the direction and feel of the Marvel Cinematic Universe in the fanfiction.
He might become more cautious. In the DC Universe, there are a lot of powerful and unpredictable entities. So, he could tone down his cocky side a bit.
She might have a diplomatic role. Given that the Avengers are a diverse group from different backgrounds, she could use her charm and intelligence to smooth over any conflicts between members. For instance, when there are arguments between Tony and Steve about the Sokovia Accords, she could try to find a middle ground and keep the team united.
Well, it would change Peter's life in a huge way. Firstly, he'd have access to Tony's vast resources. He could get better tech for his Spider - Man suit right away. Second, he'd be under Tony's protection, which means fewer villains would dare to target him directly. Also, he'd be part of the Avengers family in a more official way, learning from the other superheroes.
Well, it changes a great deal. First off, Peter would have access to far more resources and advanced technology from a very young age. Stark's influence could make Peter a more high - profile hero right from the start. His training might be more intense and scientific. Also, the dynamic between him and other Avengers would be different. He'd be like Stark's heir in a way, which would add a whole new layer to the team's relationships.
One possibility is that she could be a brilliant scientist like Tony. Maybe she works on different projects that are crucial for the Avengers. For example, she might develop new types of armor or advanced weaponry to help the team in their battles against powerful foes. She could also have a unique relationship with each Avenger. With Steve Rogers, she might initially clash due to their different views on military and technology but later come to respect each other. And with Thor, she could be fascinated by Asgardian technology and magic, leading to some interesting exchanges and collaborations.
He might become more power - hungry. Usually, he is a hero, but with the goal of taking over the world, he could lose some of his moral compass.
One way this could be possible is through some sort of time - travel or alternate reality mix - up. Maybe in a universe where the normal rules of genetics and relationships are bent. For example, if there was a powerful magic or technology that rewrote the fabric of reality, it could make Tony Stark be Steve Rogers' son. It would completely change the dynamics of their relationship and how they interact with other Avengers.
The death of Thanos at Tony Stark's hands might also change the power dynamics among the superheroes. Tony Stark would likely gain even more respect and admiration, becoming a sort of legend. This could lead to some heroes trying to emulate his methods, while others might be jealous or concerned about his new - found power and influence. Also, characters like Nebula and Gamora, who had a personal vendetta against Thanos, would have a major shift in their story arcs. They would need to find new purposes now that their main enemy is dead.
Tony Stark is very confident and self - assured. As Harry Potter, this would make him a more assertive protagonist. He might not be as hesitant as the original Harry in some situations. For example, when facing Voldemort, he would likely be more direct and less fearful. His quick - thinking nature would also speed up the plot. Instead of waiting for things to happen, he would be more proactive in finding solutions to the problems in the wizarding world.
Maybe the twin sister has a different approach to superheroing. While Tony is all about the high - tech gadgets and flashy suits, she focuses on using her intelligence to create solutions for the world's problems on a more grassroots level. She could be involved in projects like improving education in underprivileged areas or finding sustainable ways to provide clean water.
