Well, there could be some new characters created specifically for this fanfiction. Maybe a young Sand ninja who is an outcast like Naruto was in Konoha. They would bond over their shared feelings of not quite fitting in. And of course, Naruto would still be friends with his old Konoha friends who might visit him in Suna from time to time. But his main circle in Suna would include the more open - minded Sand ninjas who accept him for who he is.
Naruto might become friends with some of the Suna civilians. There could be a little girl who is fascinated by Naruto's bright orange jumpsuit and his positive attitude. Through her, Naruto gets to know the normal, non - ninja life in Suna. And among the ninja, there could be a group of young genin who look up to Naruto and want to learn from him. They would form a tight - knit group, and Naruto would be like their mentor and friend at the same time.
Gaara would be an obvious choice. Since Gaara is from Suna, he could be Naruto's close friend. They could train together and share their experiences of being jinchuriki. Kankuro and Temari might also become his friends. Kankuro could teach Naruto some of his puppet techniques, and Temari could help Naruto with wind - style jutsu training.
Well, in a 'naruto lives in suna' fanfiction, perhaps Naruto is exiled from Konoha for some reason. He then finds a new home in Suna. He starts training with the Sand ninjas and discovers new aspects of his chakra control. He also gets involved in the internal politics of Suna, trying to bring peace between different factions within the village.
One of his students could be Gaara's younger siblings. They would be eager to learn from Naruto, especially since he was the one who changed Gaara's life. Another could be some of the regular Suna academy students who are looking to become stronger shinobi. They would see Naruto as a great opportunity to learn from someone with his level of skill and experience.
He would surely meet Gaara. Gaara has had his own struggles and he might be able to understand Naruto on a deeper level. They could form an even stronger bond than before, with Gaara helping Naruto hide from those who might be looking for him in Suna.
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.
Gaara could be a main character. Since Naruto has a connection with him already, Gaara could play a big role in helping Naruto adjust to life in Suna. Maybe he becomes like a brother to Naruto in this new setting.
He would surely meet Gaara. Gaara, having had his own experiences of being an outcast, would likely be one of the first to interact with Naruto. They could share their stories and become good friends.
Sasuke could be one of his companions. Even though they've had their differences, they always end up coming together for big challenges. Sasuke's sharingan would be useful on the moon, helping them detect any hidden threats. Another could be Kakashi. His experience and knowledge would be invaluable in a new and strange environment like the moon. He could also teach Naruto and Sasuke new techniques based on the moon's conditions.
He could make friends with a young herbalist. This person might live in the forest outside Konoha and know a great deal about medicinal plants. They could help Naruto when he gets injured during his travels and in return, Naruto could protect them from wild animals or other threats.
Another possibility is a long - forgotten or hidden member of the Suna clan. They could have been shunned for their necromancer powers in the past but now, due to some events in the fanfiction, their powers are needed. This character could have a vendetta against Suna for being ostracized, or they could be a hero in disguise, ready to use their powers to save Suna from a great threat.
He might meet Gaara. Since Gaara is the Kazekage of Suna, it's very likely that they would cross paths. Naruto and Gaara have a history, so their encounter could be filled with reminiscing about their past battles and how far they've come.
