Well, he might start by being really confused. The Devil Fruits would be so strange to him compared to chakra. He could probably make friends with Luffy easily though, since they both have that adventurous spirit. And his ninja skills could come in handy when fighting pirates. Maybe he'd teach some of the Straw Hats some cool ninja moves.
In a fanfiction where Naruto goes to the One Piece world, there are a lot of possibilities. Naruto's goal - seeking understanding and friendship - would align with the values of the One Piece universe. His chakra-based powers would be a new and interesting addition. He could learn about the history of the One Piece world from Robin, and in return, he could share his own world's history. His presence could also disrupt the power balance in the world. Some pirates might see him as a threat, while others might want to recruit him. His journey in the One Piece world would be full of challenges, but also opportunities for growth and new friendships.
If Naruto were in the One Piece world, he could form interesting alliances. He might team up with Luffy and the Straw Hats. Naruto's ability to make friends easily would fit right in with the Straw Hat crew's spirit. His Rasengan could be a very powerful attack against some of the strong foes in the One Piece world. Also, his experience with dealing with different types of enemies in his own world would give him an edge in strategizing in the new and strange world of One Piece.
Well, she might be really confused at first. The magic in the Harry Potter world is quite different from the powers in One Piece. She could try to use her spells, but they might not work as expected. Maybe she'd meet Luffy and his crew, and they'd be really curious about her strange clothes and the wand she carries.
If Naruto was born in the One Piece world, he would probably be a very unique individual. His ninja skills like shadow clones could be a huge asset. Maybe he'd join a pirate crew and use his skills to fight against the Marines or other pirates. His determination to be recognized, similar to his goal in the Naruto world, would likely drive him to achieve great things in the One Piece universe as well.
Well, she could meet Luffy and his crew. Maybe she'd be amazed by their Devil Fruit powers. She might join them on a treasure hunt, using her ninja skills to help out. For example, her ability to move stealthily could be useful when sneaking onto an enemy ship.
In a fanfic where Gohan goes to the Naruto world, his presence would disrupt the balance. His Saiyan strength is on a different level compared to most Naruto characters. He might start by being confused about the ninja way and all the different clans. However, he could also introduce new concepts from his world. For example, his training methods. And he would probably make some really strange friends. Some ninjas might be in awe of his power, while others might be a bit scared. He could also end up having some really interesting battles against the strongest ninjas, like Naruto or Sasuke, which would be a clash of two very different power systems.
Naruto's ninjutsu skills could be very powerful in the One Piece world. His Rasengan, for instance, is a concentrated ball of chakra. In the One Piece world, it could be as strong as some of the more powerful Devil Fruit attacks. His ability to run up walls and trees using chakra control could also be useful in the more diverse terrains of the One Piece world, like running up the side of a ship or a rocky island.
If the One Piece characters watched fanfiction, they might be really confused at first. For example, Luffy might not understand why there are stories about him that are so different from his real adventures. Some of them could be amused, like Chopper seeing cute versions of himself in some fanfictions. But others might be offended if the fanfiction portrays them in a bad way. Zoro might get angry if he's shown as being weak in a fan - made story.
Well, he might be really confused at first. Durmstrang has a very different culture compared to what Naruto is used to in the Hidden Leaf Village. He'd probably stand out with his bright orange jumpsuit. And his ninja skills could either amaze or terrify the students there.
Well, Naruto would probably shock everyone with his ninja skills. He could show off his shadow clone jutsu, which would be really useful in combat training at UA. His determination and never - give - up attitude would also inspire the students there.
He could change a lot of things. Maybe he would prevent some tragedies that happened in the original story. For example, he might be able to save some characters who died. He could also use his knowledge from the future to make the ninja world a better place earlier, like teaching new jutsu to the younger versions of his friends.
