Naruto could come across a group of friendly travelers. They could be from different lands and have different cultures, which would be an interesting experience for Naruto. He could learn about their ways of life and perhaps incorporate some of it into his own.
He might meet some lone ninjas who live in the wild. These ninjas could have unique skills or knowledge that Naruto can learn from.
He could meet the Raikage. The Raikage might be initially skeptical of Naruto but could later see his potential. There are also other strong ninjas in Kumo like Killer Bee. Naruto might cross paths with him and they could have some interesting interactions, perhaps even training together.
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.
There could be new characters created specifically for this fanfiction. Maybe a young Suna shinobi who becomes Naruto's guide in Suna, showing him around the village and introducing him to the local way of life.
In a 'naruto moves out fanfiction', it could be that Naruto moves out to protect the village in a different way. Instead of being in Konoha directly, he sets up a base on the outskirts. This way, he can intercept threats before they reach the village and also have a place to experiment with new battle strategies.
He could meet some sort of powerful demon lords in Tartarus. These demon lords might be initially hostile but Naruto's determination and good heart could change their minds. He might also meet lost souls who are trapped there and try to help them find peace.
There could be a group of kids on the beach who are inspired by Naruto. They might approach him and ask for autographs or to show them some ninja moves. Naruto would be happy to oblige and in the process, he could discover a new talent among the kids that could be important for the future of the ninja world.
He could meet an AU version of Hinata who is more assertive and outgoing. Maybe she's a powerful ninja in her own right and not as shy as in the original story.
In this fanfiction, Naruto might run into Arthas Menethil before he fully turned into the Lich King. It would be a very different kind of encounter compared to what he's used to in his own world. He could also meet Uther the Lightbringer. Uther might be curious about Naruto's unwavering will and Naruto could be in awe of Uther's connection to the Light. Additionally, he could meet many of the adventurers and common folk in Azeroth, each with their own stories and skills.
Maybe some local tribespeople who have unique abilities or knowledge. For example, they could teach Naruto some ancient techniques or survival skills that are not known in the Hidden Leaf Village. There might also be wandering samurai or other shinobi from different regions who pass by the outpost and interact with Naruto.
He could meet some new and powerful shinobi who have different fighting styles compared to those in the Hidden Leaf. For example, some shinobi who are experts in wind - based jutsus that are unique to the western regions.
