Harry's character would become more complex. He'd have to deal with new emotions like having parents who he thought were gone forever. He'd be less isolated, and this could make him more open and friendly. He might also become more protective of his new - found family, which could lead to some interesting plot twists when facing enemies.
His confidence would grow. Knowing he has his parents' love and support directly would make him bolder. He might not be as quick to jump into dangerous situations on his own.
He would be more confident. Without the trauma of losing his parents, Harry would not have that underlying sense of insecurity. He would probably be more outgoing and less hesitant in making friends and taking risks.
His character development could be complex. On one hand, he might feel a sense of abandonment by the village, even though his parents are alive. This could lead to him exploring his own identity outside of being a Konoha ninja. He may develop new skills and ways of thinking as he adapts to life outside the village. His relationships with his parents could also change, as they try to bridge the gap between their son and the village.
If Harry Potter discovers the Tessaiga in fanfiction, his character could develop in many ways. He'd have to adapt to a different kind of power. This would require him to be more open - minded. He might start to question the traditional magic of his world more. Also, having such a powerful weapon could make him more confident, but also more cautious as he realizes the great responsibility that comes with it. His relationships with his friends might change too. For example, Ron might be a bit jealous at first, while Hermione would be eager to study the Tessaiga. Overall, his character would grow in complexity as he incorporates this new element into his life.
Naruto would be more self - assured. In the original, he was always seeking approval because he was an orphan. With his parents alive, he'd have that unconditional love and support, so he wouldn't be as desperate for others' recognition.
Harry would likely become more self - reliant. Without the support of his parents, he'd have to learn to take care of himself. He might grow more cautious and distrustful, especially if he doesn't know the real reason for the disownment.
Harry would become more confident. Having his parents' love and support directly would fill a void that has been in his heart since he was a baby. He might be less self - doubting. For example, he would no longer have those moments of wondering if he was worthy or if he could really be a great wizard like his father. He would have a stronger sense of family identity and might be more open about his emotions, since he has the love of his parents that he has always craved.
His character might be more distrustful. Since his parents left him, he may have a hard time trusting others, especially authority figures like Dumbledore. He could be more independent too, having to fend for himself from a young age. For example, he might not be as quick to accept help from others at Hogwarts.
Naruto would likely become more determined. His usual goal of becoming Hokage might be put on hold as he focuses on rescuing his parents. He would train harder, pushing his limits to gain the strength needed to face the kidnappers. This would accelerate his growth as a ninja.
At first, it might be a bit strange for all of them. But as Harry starts teaching his parents, they would begin to understand him better. They would learn about his struggles at Hogwarts, and he would learn about their lives before he was born. This mutual understanding would deepen their relationship. Harry would no longer just be their son, but also their teacher in a way, and they would grow closer through shared knowledge and experiences.
The whole story would be very different. Harry might not end up living with the Dursleys, so his personality could be less guarded and more confident. He may not have the same connection to the Sorcerer's Stone quest as he did in the original story. Also, the relationship between Harry and Snape would change completely since the reason for Snape's complex feelings towards Harry was his love for Harry's mother.
