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.
In the Marvel Universe, Harry Potter could have a different set of friends. Instead of Ron and Hermione, he might befriend characters like Spider - Man or the X - Men. His adventures would be more global or even intergalactic. His magic could also be influenced by the different energies in the Marvel world. For example, he might learn to combine his spells with the power of the Infinity Stones if he got the chance. He would also face different types of villains, some with superpowers rather than just dark magic, which would force him to develop new strategies.
Growing up in the Marvel Universe, Harry Potter would likely be more exposed to different cultures and species. At Hogwarts, it was mainly wizards and witches. But in the Marvel world, he'd encounter mutants, Asgardians, and all sorts of alien races. This exposure could make his personality more open - minded. His magic might also evolve in different ways. He could learn to use his magic to interact with technology, like using a spell to hack into a computer system or power up a piece of advanced machinery. His role in the world would be different too. Instead of just being the Boy Who Lived to defeat Voldemort, he could be seen as a key player in protecting the entire Marvel Universe from a variety of threats.
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.
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.
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.
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.
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.
As a bride, Harry Potter might have to learn new skills like walking in high - heeled shoes if that's part of the bridal look in the fanfic. He would also have to get used to different social expectations. Instead of being the heroic wizard ready for battle, he could be in a position where he is more of a center of attention in a social sense, which is very different from his usual role. This could make him more nervous or more assertive in demanding respect in this new role.
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.
If house - elves raised him, Harry would be extremely humble and have a strong sense of service. He wouldn't have the same pride as he does in the original series. He would also be very good at taking care of details and might be more of a behind - the - scenes helper at Hogwarts rather than the center of attention all the time.
Well, he could use his magic to help the Avengers in battles. Maybe he could use a spell to disarm Thanos of the Infinity Stones. His broomstick flying skills would also be useful for quick getaways or aerial attacks.
