Well, Cedric Diggory could be a friend. He is popular and kind, and would welcome them. Cho Chang might also be their acquaintance or friend as she is friendly and sociable. And then there are the Hufflepuff students in general. Since Hazel is very kind - hearted like many Hufflepuffs, she could easily make friends within that house, and through her, Percy and Piper could also have connections with the Hufflepuff students.
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, 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 befriend Neville Longbottom. Neville has his own journey of growing stronger, and Naruto, with his immortality and vast experience, could inspire him further. Luna Lovegood might also be drawn to Naruto because of his other - worldly presence. She could find his ninja skills and his different way of life very interesting. And of course, the Weasley twins. They would be excited to learn about Naruto's pranks and ninja tricks, and might even collaborate with him on some new and crazy schemes 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.
Well, without reading the specific fanfiction, it's hard to say exactly who they are. But they could be a group of new students who have some special abilities or backgrounds. Maybe they are friends who have grown up together in the wizarding world.
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 might be a great professor for a class on the study of magical creatures. His curiosity and ability to befriend all kinds of beings in his own world could translate well. He could teach students how to approach magical creatures with respect and understanding, just as he did with the giant toads and other beasts in his ninja journey.
In a fanfiction where the Avengers go to Hogwarts, there would be a clash of cultures. The Avengers are used to a world of high - tech and superpowers based on science, while Hogwarts is all about magic. Iron Man would likely be skeptical of magic at first, but as he sees the power it holds, he might start to think of ways to integrate it with his technology. The students at Hogwarts would be in awe of the Avengers, and the Avengers would have to learn to respect the magical world's traditions.
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.
