He might find himself in a world with different versions of his friends and enemies. For example, Sasuke could be a peaceful farmer instead of a vengeful ninja. Naruto would probably be confused at first but then use his skills and positive attitude to adapt and try to make things better in that new universe.

He might make friends with Harry Potter and his gang. His rasengan could be seen as a very strange and powerful spell - like thing in the wizarding world. And he'd surely bring a new kind of energy and chaos to Hogwarts.
Well, Naruto would likely bring his sense of determination and never - give - up attitude to Earthland. In Earthland, which has its own set of power systems and magic, Naruto could start to learn and combine his ninja skills with local magic.

Well, in some Naruto parallel universe fanfiction, there could be a world where the Akatsuki are the good guys. They might be trying to save the ninja world from a greater, hidden evil that the regular villages are unaware of.

One of the most popular characters in Naruto parallel universe fanfiction has to be Orochimaru. His thirst for knowledge and his morally grey nature make him a very interesting character to rewrite in different universes.

In parallel universes, she could have different training methods and develop into a completely different kind of ninja, perhaps one with unique healing or combat abilities that are not seen in the original story.
When Naruto goes to a parallel dimension in fanfiction, it's a whole new world of possibilities. He could encounter a dimension where his parents are still alive. This would be a huge emotional moment for him. He might also find that the Akatsuki in this dimension has different motives or is even a force for good. Naruto's own values and beliefs would be put to the test as he tries to understand and navigate this strange new place. His usual techniques like the Rasengan might not work as effectively, forcing him to learn and innovate on the fly.
In fanfiction, if Naruto is sent to a different dimension, he might face all kinds of strange new powers and enemies. For example, he could encounter magic that is completely different from chakra.
