His relationship with Hogwarts students would be very different. Instead of growing up with them, he would be an outsider. When he finally meets them, they might be in awe of him or even a bit afraid because of his different upbringing.
With the teachers at Hogwarts, Harry might not have the same kind of trust or respect as he does in the original story. Since he grew up in the Forbidden Forest, he may have a more natural and wild approach to magic which might conflict with the traditional teachings at Hogwarts.
His relationship with magical creatures would be much deeper. Having grown up among them in the Forbidden Forest, he would consider them his family. He would be more likely to side with the creatures in any disputes between them and the wizarding world, which could lead to some interesting storylines.
His relationships would likely be more guarded. He might have a hard time trusting people at first. For example, when he meets Ron and Hermione in the wizarding world, he would be more hesitant to form a friendship. His idea of friendship might be more about survival and mutual benefit rather than the more innocent and pure form in the original story.
His magic might be more in tune with Japanese elements. For instance, his Patronus could take on a form related to Japanese mythology, like a Kitsune. His spell - casting could be more fluid and graceful, influenced by Japanese martial arts movements. Since Japanese magic could be more about harmony with nature, his magic might also be more attuned to the natural elements around him, like using the power of the wind that blows through Japanese bamboo forests.
He might be more used to high - tech gadgets and modern technology. In Hogwarts, he was surrounded by magic, but in the Marvel Universe, he'd also have to deal with things like Iron Man's suits and Wakanda's advanced technology. His view of the world would be broader, and he might be more adaptable to different situations.
He might encounter magical creatures that are not known to most wizards. For example, he could meet a rare breed of unicorn or a group of centaurs who take him under their wing and teach him their ways of magic and life in the forest.
In fanfiction where Harry Potter grew up in Japan, his appearance could be different too. He might be dressed in traditional Japanese wizard robes. His magic could be influenced by Japanese magic traditions. He would probably learn different spells that are unique to Japanese wizardry. Also, his friends would likely be of different ethnic backgrounds, and they would celebrate Japanese magical festivals together.
His relationship with Annabeth might be more strained. Since he grew up in the wild, he would be less accustomed to the structured world of Camp Half - Blood where Annabeth thrives. They might have a harder time understanding each other's ways of life at first.
His character would likely be distorted. He might become more cynical about relationships in general. Since Hetai fanfiction often portrays relationships in a rather improper and unrealistic way, Harry might lose his sense of the true, deep - seated values of friendship and loyalty that are so central to the original story.
If Harry grew up in Japan in fanfiction, his view of the magical world would be shaped by Japanese culture. Japanese art forms like origami could have magical applications. His spells might be chanted in Japanese. His enemies could also be different, perhaps based on Japanese dark magic concepts. He would grow up in a society that values harmony, so his approach to conflict, both in the magical world and personal relationships, would be more about mediation and finding common ground rather than direct confrontation like in the original story.
Hermione would probably be initially shocked but then try to research ways to help Harry control his vampire side. She might look for spells or potions in the library. Ron, on the other hand, might be a bit more fearful at first. He might keep his distance until he realizes that Harry is still the same person deep down. Dumbledore would likely be very understanding and offer his guidance, seeing Harry's new situation as another opportunity for him to grow and learn in a different way.
His relationship with Hinata might be different. She could be initially taken aback by his new look but then come to love him all the same. His friends like Shikamaru and Kiba might tease him more about his red hair, creating a new dynamic in their friendships. And his relationship with his son, Boruto, could also change as Boruto might have a different perception of his father with this new appearance.
