Naruto would be very friendly and outgoing, quickly making friends with many Hogwarts students. He'd be eager to share his ninja stories and learn about magic from them. Sasuke would be more aloof at first. He might only interact with students who he sees as strong or useful. Gaara would be a bit of an enigma. Some students might be intimidated by him, but those who get to know him would find his quiet strength appealing.
Well, Naruto would probably be the one to break the ice. He'd join in on Quidditch matches, cheering loudly and maybe even trying to play despite not fully understanding the rules. Sasuke would likely keep to himself in the library, but if a Hogwarts student challenged him in a duel or a battle of wits, he'd be more than happy to engage. Gaara, on the other hand, would be more of a loner. But when he does interact, it would be in a very matter - of - fact way, like when he's helping in a Herbology class or something.
Percy would probably be very friendly and try to form study groups with the Hogwarts students. He's used to being a leader, so he might even start some new clubs. Thalia would be a bit more standoffish at first, but once she gets to know some students, she'd be very protective of them. Nico would be the mysterious one. The Hogwarts students might be a bit scared of him at first, but once they see his softer side, they'd become friends.
Well, Naruto would be excited about all the new magic things at Hogwarts. He'd want to make friends right away and might try to use his chakra in the magic classes, which could lead to some interesting and perhaps chaotic situations. Gaara, on the other hand, would be more reserved. He might find the Forbidden Forest interesting as it has a similar sense of mystery to his own desert back home. They both could have a big impact on the house rivalries at Hogwarts.
Naruto would adapt by being his usual enthusiastic self. He would be all over the place, asking questions, and getting into adventures. He might use his ninja agility to his advantage in things like Quidditch, even if he doesn't fully understand the game at first. Sasuke would be more cautious. He would study the magic system intently, comparing it to his ninja knowledge. He might have a hard time adjusting to the more laid - back atmosphere at Hogwarts compared to the intense ninja training environment he's used to. But as he starts to master some magic, he would gain confidence and start to feel more at home.
Ichigo would approach the Hogwarts faculty with an open mind. He might seek out professors like Dumbledore for advice on how to handle the new magical environment while also dealing with his own inner darkness. Dark Ichigo would likely view the faculty as obstacles in his path to power. He might challenge them in a more aggressive way, like trying to outwit them in magical duels or contests of knowledge. However, the faculty, being experienced, would not be easily intimidated by him.
They could have all kinds of adventures. Maybe they would be sorted into different houses at Hogwarts. Naruto might end up in Gryffindor with his courage. Sasuke could be in Slytherin due to his ambition. And Gaara, perhaps Hufflepuff for his loyalty in his own way. They could team up to fight against dark wizards who are threatening Hogwarts, using their ninja skills combined with magic.
Naruto would likely struggle at first. He's used to ninja training, not magic spells. But his determination would make him work hard to catch up. Gaara, being more introspective, would observe quietly and then start to master the curriculum at his own pace.
Some students would be super excited. The younger students especially would be thrilled to see cute Pokémon like Eevee around the castle. They would be eager to learn from them and make friends with the Pokémon.
Well, one possible plot could be that Naruto and Sasuke are somehow transported to the wizarding world. Naruto might be excited to learn new magic skills and make friends at Hogwarts. Sasuke, on the other hand, would be more interested in the power aspect of magic. They could get sorted into different houses, like Naruto into Gryffindor for his bravery and Sasuke into Slytherin perhaps because of his ambition. And then they have to deal with the typical Hogwarts problems like exams, dealing with bullies, and also the threat of the Dark Arts. Maybe they would find a way to combine their ninja skills with magic to defeat a common enemy.
Naruto could use his superhuman stamina to keep watch all night. His positive energy would also boost the morale of the Hogwarts students. Sasuke, on the other hand, would use his combat skills. He could set up traps around the perimeter of Hogwarts using his ninja knowledge.
If she has the power to read minds like some Cullens, it could give her an advantage in divination or in dealing with other students. But it might also get her into trouble if she's caught using it unethically. Her super strength could be useful in Defense Against the Dark Arts practical lessons, but she'd have to be careful not to accidentally harm her classmates. Also, her powers might interact in unexpected ways with magic, like when she tries to use a spell on an object and her vampire strength affects the outcome.
