Well, one possibility could be that Naruto has to adapt to the different culture in Kumo. He might face challenges in making new friends as the people there have different values and ways of life compared to Konoha. He could also discover new jutsus unique to Kumo and incorporate them into his own fighting style.
In a fanfiction where Naruto lives in Kumo, his training would likely be different. The terrain and resources in Kumo are distinct from Konoha. He could train with the strong ninjas in Kumo and learn from their experiences. This would make him a more versatile ninja. And perhaps he would form a team with some of the local Kumo ninjas, and they would go on missions together, facing new threats and enemies that are specific to the area around Kumo.
His character might become more hardened. Kumo is known for its tough ninjas, and living there would expose Naruto to a more cut - throat environment. He may lose some of his naivete and become more calculating in his actions.
One possible plot could be Naruto using the bunker as a secret training ground. He could practice new jutsus without being disturbed, and perhaps discover some hidden power within the bunker. Maybe there are ancient markings or seals in the bunker that he deciphers, leading to a new level of strength.
I'm not sure specifically as it depends on the author's creation. But it might involve Naruto having some sort of conflict with Kumo and then abandoning it. Maybe there are issues like political differences, or problems with the shinobi from Kumo that lead Naruto to this decision.
Naruto would probably use his friendly and outgoing nature to adapt. He'd start by getting to know the people around him, like his new family and the local ninjas. He might also be interested in Kumo's unique jutsu and training methods, which would help him fit in. And of course, he'd keep his goal of promoting peace between Konoha and Kumo in mind, which would give him the motivation to overcome any difficulties in adapting.
If Naruto is kidnapped by Kumo in fanfiction, it could lead to a series of intense battles. Naruto himself might try to escape on his own using his ninja skills and the power of the Nine - Tails. His captors in Kumo would probably want to extract some sort of information from him, like the secrets of the Nine - Tails or Konoha's defense strategies. However, Naruto is a tough character and would surely put up a fight.
In a 'Naruto Raised in Kumo' fanfiction, Naruto would likely face different challenges. Kumo has its own political situation. He might be trained in Kumo's harsh training regimens. Also, his relationship with the Raikage could be a key factor in his development, as the Raikage's leadership style is quite different from the Hokage's.
Well, in a fanfiction where Naruto joins Kumo, his presence would surely shake things up. He has a strong sense of justice which might conflict with some of Kumo's more cutthroat traditions at first. But he could also be a bridge between Kumo and Konoha, leading to better relations between the two villages. He would have to adapt to Kumo's harsher environment, both physically and socially. And perhaps, he would inspire the younger generation of Kumo ninja to be more like him, brave and always striving to protect others.
Well, a lot would change. Firstly, his connection to the Nine - Tails would be perceived differently in Kumo. Kumo has its own political and social environment. Naruto might not face the same level of ostracism as he did in Konoha. He could be seen as an asset from the start. Also, the story's power dynamics would shift. Kumo's ninja might have different ways of dealing with the power of the Nine - Tails within Naruto. And his relationships with other villages, especially Konoha, would be more complex and likely start from a more adversarial position.
Maybe in the fanfiction, Naruto neglected Kumo because he was too focused on his own village's problems. But then something major happens in Kumo, like a powerful enemy targets them. Naruto realizes his mistake and goes to Kumo to make amends. He teams up with the Kumo shinobi, and they work together to fend off the threat. Along the way, he learns about Kumo's unique culture and forms strong bonds with their ninja.
Perhaps Naruto is in Kumo to search for a missing Konoha ninja. While there, he uncovers a conspiracy within Kumo that threatens both villages. He then has to team up with some of the Kumo ninjas who initially distrusted him to stop the threat.
