Well, he might find himself in a world with completely different chakra rules. Maybe in this new world, his ninja skills are either overpowered or nearly useless. He could meet new characters that are similar to his friends in Konoha but with different personalities. For example, he might find a version of Sasuke who is more friendly from the start.
Naruto could become more curious. A different world means new things to explore, new cultures, and new powers. He would be eager to learn about everything, which could make him seem more inquisitive than he already is. He might start asking a lot of questions to understand how this new world functions.
He may find that his ninja skills are either very useful or completely ineffective in the new world. If the new world has a different form of combat, Naruto would have to adapt quickly. Also, he could encounter new forms of nature energy or magic that he has to learn to control. There might be a love interest for Naruto in this new world as well, which could add a whole new layer of complexity to the story.
Naruto would probably be really confused at first in the Pokemon world. But then he'd start to explore. He might mistake a Pokeball for some kind of ninja tool at first. However, once he figures out how things work, he could become a really strong Pokemon trainer. His determination, which is one of his main traits in his own story, would help him a great deal in this new world. He would not give up easily when it comes to training his Pokemon or facing tough opponents in Pokemon battles.
Well, he could expect adventures that test his limits. Maybe in this different dimension, there are no villages and ninjas are more like lone wolves. Naruto would have to learn to survive in this new environment where the rules are different. He might also find that his reputation as a hero in his own world means nothing here, and he has to prove himself all over again. This could lead to him having to fight for respect and to make new friends. And of course, there could be new and strange creatures that he has to either fight or befriend.
Well, Naruto might be really surprised at first. He could find that the fighting styles are different as they are designed by females. Maybe he would have to adapt to new social rules and ways of communication. For example, he might need to be more polite in a different way than he is used to in his own world.
Naruto's positive and determined personality will likely help him a great deal. His never - give - up attitude means he won't be easily discouraged in the face of new challenges in the different dimension. He'll keep trying to figure things out, whether it's understanding new cultures or fighting new enemies. His friendly nature might also help him make allies quickly. People in the new dimension will probably be drawn to his outgoing and kind - hearted personality.
His relationship with his father would be completely different. Instead of growing up without him, he could have a normal father - son relationship. His father could teach him ninjutsu from an early age.
He could meet female versions of his existing friends like a female Sasuke or Sakura. They might have different personalities while still retaining some of the traits of their male counterparts. For example, a female Sasuke could be just as strong - willed but with a more feminine touch in her fighting style.
