Well, it could strengthen his friendships. His friends might respect him more for being open about his intelligence. For example, Hermione would be glad to have someone as smart as her to discuss complex magic with. Ron might initially be a bit jealous but would soon realize how useful Harry's intelligence can be in their adventures.
In terms of his enemies, Voldemort might become more wary of him. Harry not hiding his intelligence means he can come up with more clever strategies against the Dark Lord. His fellow students who are on the side of the Death Eaters might also try to undermine him more because they see him as a greater obstacle due to his obvious intelligence.
In such a fanfiction, Naruto keeping to himself might make others initially find it hard to approach him. For example, his friends like Sasuke and Sakura might be a bit confused at first. Sasuke, who is also a bit of a loner in his own way, might not know how to deal with this new Naruto. Sakura, on the other hand, might try harder to break through his shell. This could lead to some strained relationships at the start, but as the story progresses, those who truly care about Naruto would try to understand him better and build deeper, more meaningful relationships with him.
Well, it could make his relationships quite complicated. For example, with Sakura, his lack of understanding of love might lead to him misinterpreting her signals. He might see her as just a good friend when she has deeper feelings for him. And with his friends like Sasuke, Naruto's confusion about love could make it hard for him to fully support Sasuke in matters that are related to love or emotional bonds, as he doesn't really get it himself.
He might pretend to not understand complex concepts. For example, when others are discussing advanced magic theories, he could act confused even though he actually gets it.
He may also choose to stay quiet during discussions where his knowledge could shine through. Instead of speaking up and showing off his intelligence, he lets others do the talking and only chimes in when it's necessary or when he can play dumb and ask simple questions.
His intelligence might make his relationships more complex. With his friends, they could look up to him for his smarts. For example, they might come to him for help with their studies or for solving problems. But it could also create a bit of distance at times. If he's always thinking several steps ahead, his friends might have a hard time keeping up with his ideas.
Well, in his relationships, it causes a lot of confusion. His friends may try to communicate their emotions to him, but he just doesn't get it. This can lead to misunderstandings and even arguments. In a romantic relationship, it would be even more difficult. He might not understand the concept of compromise or how to make his partner feel special. Since he doesn't understand emotions, he could end up making his partner feel unloved or unappreciated.
His intelligence might make him more respected by his peers. Instead of just being known for his scar and his connection to Voldemort, his friends see him as a true intellectual. Hermione might become more of an equal to him in terms of academic discussions rather than just being the one who always has the answers. Ron, on the other hand, could feel a bit intimidated at first but then grow to be proud of his friend's intelligence.
With the teachers, like Dumbledore, he might be treated differently. Dumbledore might see this transformation as an opportunity for Harry to learn new things about the wizarding world from a different perspective. And some of the more traditional teachers might have different expectations of Harry's behavior in class now that he is a girl.
With Hermione, she would probably be very interested in researching more about Parseltongue and how it works in Harry. She might try to find ways to help Harry control it better or understand its full potential. This could strengthen their bond as they work together on this unique aspect of Harry's magic.
Well, if Goku keeps his memory in fanfiction, it could strengthen his relationships. For example, with his friends like Krillin, he'd be able to recall all their past adventures more vividly. He could offer better advice based on past experiences, making their bond deeper. Also, with his family, he'd be more present in their lives, remembering important events in their relationships, which would lead to more meaningful interactions.
