For Naruto's friends like Shikamaru and Choji, they would be quite surprised. Naruto might start to act more like Tobirama in some ways, which could be a bit off - putting at first. He could be more strict or more focused on the long - term goals of the village. This might cause some friction in their friendships until they understand what's going on. With the elders of the village, Naruto could gain more respect as Tobirama was a highly respected figure. But it could also make some of them wary, as they might fear Naruto using Tobirama's knowledge in ways they don't like.
His relationship with the younger generation of ninja would also be impacted. Naruto has always been a role model for them. But as Tobirama's reincarnation, he could become more of a mentor figure. He might start teaching them things in a more traditional, Tobirama - like way. This could inspire some of the younger ninja to study more about the village's history. However, some of the more rebellious ones might resist this new Naruto, thinking he's become too old - fashioned.
In fanfiction, anything is possible. So, Naruto could be Tobirama's reincarnation. Some fanfic authors like to play with the idea of reincarnation to bring new elements to the story. They might make Naruto inherit some of Tobirama's chakra nature or jutsu. This can create unique scenarios where Naruto has to deal with the memories or expectations that come with being Tobirama's reincarnation. It can also change the dynamics between Naruto and other characters, like Sasuke, as they might view Naruto differently if he has such a connection to an important figure from the past.
As for his relationship with the villagers, some might fear him more because of his connection to Indra. They could see him as a potential threat, like they did in the beginning when they were afraid of the Nine - Tails within him. However, others might see it as a sign of Naruto's importance and start to respect him even more, believing that he is destined for great things because of this reincarnation.
Well, Naruto's relationship with Hinata could be affected in several ways. If Naruto is reincarnated as Kaguya, Hinata might feel a bit distanced from him at first. She would be confused about this new side of Naruto. Also, the other villagers might start to fear Naruto, which could put a strain on his relationship with the whole village. But if Naruto can prove that he's still the same person deep down, he might be able to repair those relationships. His relationship with Kakashi would also change. Kakashi, being a knowledgeable person, would try to guide Naruto through this new development.
One implication could be a change in Naruto's abilities. He might gain some of Tobirama's water - based jutsu or his talent for creating complex ninja techniques. Another is in his relationships. The village elders might treat him differently, perhaps with more respect or suspicion depending on their views of Tobirama.
Well, it depends on what you consider 'good'. Some people might like ones that focus on Tobirama's reincarnation's impact on the existing Naruto world politics. For example, there could be a story where the reincarnation has to deal with the power struggles between the different ninja villages in a new and interesting way. Others might prefer more character - driven stories that explore Tobirama's relationships with the other characters in his new life. You really have to dig through the available fanfictions to find the one that suits your taste.
Well, identity is a big theme. The reincarnation has to figure out who they are in relation to Tobirama. Are they a complete reincarnation with all of Tobirama's memories and skills? Or are they a new person with just a connection to Tobirama? Also, there's often the theme of redemption. Maybe Tobirama had some regrets in his past life, and the reincarnation has the chance to make things right. And of course, the theme of friendship and alliances, as the reincarnation has to interact with the existing characters in the Naruto universe and form relationships with them.
One possible Naruto fanfiction with Tobirama's attitude could be where Naruto, in a strange turn of events, starts to exhibit the same no - nonsense and strict attitude as Tobirama. For example, he might become more firm in his leadership within Team 7. Instead of his usual go - with - the - flow style, he would demand more discipline from Sasuke and Sakura, much like Tobirama would have expected from his subordinates.
His relationship with Sasuke would be very different. Sasuke might see Naruto as more of a rival or a threat now that he has Whitebeard's power and influence. Naruto, on the other hand, would probably try to get Sasuke to understand his new purpose of bringing unity. His friends like Sakura and Kakashi would also be a bit in awe at first, but then they would support him as he tries to use his new powers for good.
Naruto's relationship with his sensei, like Kakashi, would also change. Kakashi would be extremely vigilant and try to train Naruto to control the Sephiroth - like powers. He might also be researching about this strange phenomenon. As for his friends in the village, some might be afraid of him, while others might see it as an opportunity for the village to become stronger. But overall, Naruto would feel a bit isolated as he's different now.
It could strengthen his relationships. His friends might be in awe of his new power and support him more. For example, Sasuke could see Naruto's black lightning as a sign of his growth and respect him even more, leading to a deeper bond between them.
