Gohan might form a mentor - like relationship with some of the younger Fairy Tail mages. He has a lot of combat experience and could teach them about discipline and the importance of training. He could also be friends with the more powerful mages, like Natsu, and they could spar together to improve their skills.
He could potentially have a rivalry with some of the Fairy Tail members who are prideful in their strength. For instance, Gajeel might see Gohan as a threat and want to prove himself stronger. On the other hand, Gohan could form a close bond with Levy, as she is intelligent and could be interested in learning about Gohan's different world. Also, he might be seen as a big brother figure to Wendy, given his kind nature and his ability to protect others.
Sora would probably form really friendly relationships. He's a very positive and kind - hearted character. He'd likely get along well with Natsu because they both have a lot of energy and a strong sense of justice. He might also be friends with Lucy as she is friendly and open - minded, and they could share stories about their different adventures.
He could have an interesting relationship with Natsu. Natsu is known for his hot - headedness and love for a good fight. The Hulk, with his anger - based power, could be a great sparring partner for Natsu. They might start off as rivals, constantly trying to outdo each other in terms of strength. Or they could become friends who understand each other's need to let out their pent - up energy. He could also have a relationship with Lucy. Lucy might be a bit intimidated by him at first, but as she gets to know him, she could see his good side and try to help him control his anger. Maybe she could use her celestial spirits to calm him down in some situations.
Goku would probably get along well with Natsu. They both have a love for fighting and a strong sense of justice. They might constantly challenge each other to friendly battles to see who's stronger.
Gohan's powers could be a great addition to the Fairy Tail universe. His Saiyan strength and ability to go Super Saiyan would make him one of the most powerful mages in the guild. He could use his ki blasts like powerful magic attacks, and his speed and agility would be useful in battles against dark guilds.
He would probably form some interesting friendships. He might befriend people who are into martial arts or those with a sense of justice like him. He could also have a mentor - like relationship with some, teaching them about his ninja ways.
Tsuna would probably form some interesting relationships. He might be friends with Izuku Midoriya. Both start off as rather timid characters and have to grow into their powers. They could bond over their shared experiences of self - discovery and improvement. Tsuna could also have a friendly rivalry with Bakugo. Bakugo's brash nature might clash with Tsuna's more laid - back (initially) personality, but they could also learn from each other in terms of combat and determination.
If Naruto was born in the Marvel universe, he would probably have a complex relationship with Thor. On one hand, they both have powerful abilities. Thor has his godly powers and Mjolnir, while Naruto has his chakra and jutsu. They might start off as rivals, each trying to prove their strength. But over time, they could come to respect each other. Naruto would be fascinated by Thor's Asgardian heritage, and Thor would be intrigued by Naruto's ninja way. And Naruto could also form bonds with the Avengers as a whole, bringing his own brand of heroism and determination to the team.
He would have his Rinnegan as well. With the Rinnegan, he could potentially control the six paths of magic in the Fairy Tail universe. For instance, he could use the Deva Path to manipulate gravity - something not common in the Fairy Tail magic system. His Preta Path could absorb magical attacks, making him a formidable opponent against even the most powerful Fairy Tail mages. His other paths like the Asura Path could give him additional mechanical - like appendages with enhanced strength and weaponry, which would be a new and terrifying concept in the Fairy Tail world.
Hermione would probably have an interesting relationship with Levi. Levi is all about discipline and efficiency, and Hermione's organized and studious nature could either clash or complement his. They might start off at odds, with Levi being skeptical of her magic, but over time, they could learn to work together. And she might also develop a relationship with Eren. Eren's determination and drive could remind her of Harry Potter in some ways, and she could try to guide him in a more rational way, using her wisdom and knowledge.
Well, in the Fairy Tail high school fanfiction, Natsu is a really interesting character. He's full of enthusiasm, just like in the original Fairy Tail. In high school, he could be that popular kid who's not afraid to break the rules a bit. He might be constantly getting into friendly competitions with other students, especially when it comes to sports or magical battles in the fanfiction world. His loyalty to his friends is unwavering, and he'd do anything to protect them from bullies or any other threats in the high school setting.
