As a child, Deku would likely be more naive. He might not fully understand the extent of the challenges that lie ahead in his journey to become a hero. His admiration for heroes would be pure and untainted. Uraraka as a child could be more impulsive. For example, she might use her quirk without thinking about the consequences as much as she would when she's older. She'd also be more likely to show her emotions openly, like her excitement about hero - related things.
Child Deku would be in a more formative stage of his self - confidence. He might look up to heroes even more desperately, and be more easily influenced by the opinions of others. His determination would be there, but it would be a bit more fragile. Regarding Uraraka, she could be more bubbly and outgoing as a child. She may not have developed her strategic thinking as much yet, so she would rely more on her natural instincts and her quirk's basic abilities. This would make her interactions with Deku really interesting, as they both grow and learn from each other.
One possible plot idea could be that they meet at school for the first time. Maybe Deku is being bullied and Uraraka stands up for him. This would start their friendship early on. They could then discover their shared dreams of becoming heroes together.
They could meet during a local hero parade. Child Uraraka is excited to see all the heroes, and Child Deku is there with his notebook, jotting down details about the heroes' costumes and quirks. They accidentally bump into each other. Uraraka apologizes and Deku is so star - struck by the idea of meeting another hero - enthusiast that he forgets to be shy for a moment. They start chatting about their favorite heroes and find out they have a lot in common.
It could be that they meet at school. Uraraka is the new girl in class and Deku is the shy but friendly boy. At first, Uraraka is a bit intimidated by the other kids' quirks, but Deku encourages her. He shows her how he's also been working hard to develop his own quirk, even though it was a late - bloomer. They bond over their insecurities and shared love for heroes.
The child in the fanfiction could be different in terms of their goals. Naruto always dreamed of becoming Hokage to gain recognition. Their child, on the other hand, might be more interested in exploring the world outside the Hidden Leaf Village. Maybe they want to learn about different ninja cultures and techniques. This could lead to a story where they set out on a journey, with Naruto and Hinata being a bit hesitant at first but eventually supporting their child's dreams. And along the way, the child could encounter new friends and enemies, and develop their skills in ways that neither Naruto nor Hinata had expected.
The child might be different because of the unique combination of Harry and Hermione's genes. For instance, they could have an uncanny ability to solve complex magical problems quickly, drawing on Hermione's logical thinking and Harry's quick - wittedness in dangerous situations.
Both of them might also feel a sense of unease. Seeing a version of themselves from the future could make them realize how much they are changing and how uncertain their future really is. It could also make them question their current identities and goals. They might start to have an internal struggle as they try to reconcile their present selves with the potential future versions they are seeing.
Lily is kind - hearted and magical, while Petunia is often bitter and mundane. Their personalities could clash as Petunia might envy Lily's abilities and life. James is confident and a bit of a prankster. Vernon is strict and set in his ways. James' carefree nature could really annoy Vernon. However, Lily's kindness might also start to soften Petunia over time. And if James tries hard enough, he could find a way to get Vernon to at least tolerate him.
His friends would be really shocked at first. Uraraka might be the first to try and comfort him, seeing as she has a kind heart. Bakugo, on the other hand, would probably be both confused and a bit angry at the situation. All - Might would likely feel a sense of responsibility to protect Deku even more than before. The teachers at UA would probably start researching how to reverse the transformation immediately.
The main differences are in their expressions and some minor details of personality. In the manga, Deku might seem a bit more intense, while in the anime, he's sometimes presented a bit softer.
In their normal selves, Naruto and Hinata have a relationship based on admiration and love. But as Dark Naruto and Dark Hinata, it could be a relationship based on power and mutual goals. They might see each other as tools to achieve their dark desires, rather than as romantic partners. For example, they could use each other's abilities to take over territories or gain control over powerful ninja techniques.
