Maybe an old hermit who lives in the mountains outside Konoha adopts Naruto. The hermit could be a master of some long - forgotten ninjutsu. Under his tutelage, Naruto would learn these ancient techniques and use them to protect the land around the hermit's dwelling. He might also gain a deeper understanding of nature and chakra from the hermit.
One possibility could be that Naruto leaves Konoha due to feeling ostracized still despite his efforts. He might start a new life in a small village on the outskirts. There, he could train in solitude, learning new jutsus that are unique to the local environment. He may also encounter new characters who help him see a different side of the ninja world, away from the politics and rigid structure of Konoha.
One possible plot could be that Naruto is adopted by a powerful ninja from another village. This new family might train him in different techniques and he could grow up with a new perspective on the ninja world. Maybe he would form alliances with his new village against Konoha at first, but later realize the importance of unity among all villages.
Well, one possibility could be that Naruto grows up in a hidden location outside the village, learning different skills and having unique adventures. Maybe he meets a hermit who teaches him ancient ninja arts that are not known in the village.
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.
Maybe a wandering merchant or traveler who discovers Naruto outside the village and takes him under their wing for a while. This character could introduce Naruto to different cultures and ways of life, which would greatly influence his character development in the fanfiction.
Perhaps Naruto is raised in a non - ninja community. He could grow up with normal people and have no idea about his chakra or ninja heritage at first. But then, some events might occur that expose his true nature and draw him into the ninja world. He would have a very different perspective compared to a Konoha - raised Naruto, as he didn't have the indoctrination of the ninja village from a young age.
Naruto's character would likely be more independent. Without the structure and support system of Konoha, he would have to rely on himself more. He might be more distrustful of large organizations, having not grown up with the sense of community that Konoha provides.
Jiraiya's old contacts from his travels could also become Naruto's allies. Jiraiya was well - known and had many friends and acquaintances. Naruto could seek out these people and they, out of respect for Jiraiya, might help Naruto. For example, some of the toads from Mount Myoboku could be on his side.
Well, in some fanfictions, Naruto might outsmart Konoha by using his unique knowledge of the village's secrets that others don't know. For example, he could use his understanding of the old tunnels under Konoha to his advantage in a situation where he needs to escape or gain an upper hand in a conflict.
