Maybe she meets Kakashi in secret. Kakashi has always been an important figure in Naruto's life. If Female Naruto exists in the fanfiction, she might seek Kakashi's advice on some personal or village - related matters in a private meeting. It could be about her training, or some secrets she has discovered that she doesn't want others to know yet.
She could meet Sasuke in secret. In many fanfictions, their relationship is complex and full of unspoken feelings. Meeting in secret would add more mystery and drama to their interactions, perhaps to discuss their shared past or their future together away from the prying eyes of the village.
It's possible that she meets Hinata in secret. They could be sharing secrets about their relationships or their growth as female ninjas. Hinata might be confiding in Female Naruto about her feelings for Naruto, or they could be discussing new jutsu techniques that are more suitable for female ninjas.
He could meet an old hermit ninja who has been living in the hideout for ages. This hermit could have unique skills or knowledge that Naruto has never seen before.
He might meet the spirit of an ancient ninja who was the keeper of the library. This spirit could guide Naruto through the library and teach him things that no one else in the present day knows.
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.
Naruto may run into some friendly space explorers who are amazed by his ninja skills. They could help him navigate the strange new world of space and introduce him to advanced technologies that are different from what he's used to in the Hidden Leaf Village. There might also be some wise, old beings in space who can teach Naruto new ways to master his chakra.
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.
He could meet the Flash. The Flash would be intrigued by Naruto's speed and his ability to move in bursts, which is somewhat similar to his own super - speed. They could have a friendly race or even team up to fight a common enemy.
