Who could Naruto meet in a 'Naruto travel to the future fanfic'?

Naruto might meet his future children. He would be able to see what kind of people they are and what their dreams and aspirations are. It would be an emotional moment for him, seeing his family in the future.

There's also the possibility that the main antagonist is an outside force from another dimension or a powerful entity that was awakened in the future. This entity might see the ninja world as a threat or simply want to conquer it for its own gain. Naruto would need to figure out how to defeat this unknown and powerful foe during his time in the future.

In such a fanfic, Naruto might be shocked by the advanced technology in the future. He could see flying cars and buildings that reach the sky. His ninja skills would be put to the test in a whole new environment where physical strength might not be as dominant as it was in his time.

Naruto might encounter a group of rogue ninjas. At first, they seem like enemies, but as he gets to know them, he realizes they have their own reasons for being outcasts. They could teach Naruto some unorthodox fighting styles that are not taught in the Leaf Village. Also, there could be a mysterious traveler who has knowledge about Naruto's family that even he doesn't know. This traveler could be the key to unlocking some hidden power within Naruto.

He could meet Konan. Since Konan is an important figure in Amegakure, Naruto might have some interesting interactions with her. They could exchange ideas about peace and the future of the ninja world.

There could be some old and wise shinobi in Suna that Naruto encounters. These shinobi could have stories about the history of Suna and its relations with other villages. Meeting them would give Naruto a broader perspective on the ninja world. Also, he might meet some civilians in Suna who are affected by the village's politics and shinobi activities. Interacting with them would make Naruto more aware of the real - life impact of being a shinobi in Suna.

Naruto might meet some young and talented Kumo ninjas. They could be eager to test their skills against Naruto or learn from him. Maybe there are some unique characters like a Kumo ninja with a special bloodline limit that Naruto has never seen before.

He could meet a lost shinobi from a different village. This shinobi might have been stranded there for a long time and has some valuable knowledge or skills that Naruto could learn from.

He could meet other rogue ninjas. These are ninjas who have left their villages for various reasons, and they might be on a similar journey as Naruto. They could either help him or try to take advantage of his situation.

There's a chance he could meet an older and wiser Kakashi. Kakashi might have new insights and stories to share with Naruto from all the years that have passed. And also, he could run into future shinobi who look up to him as a legend from the past.
