Another aspect could be his relationship with the other characters. Since he already knows about Kurama, he can better explain things to his friends like Sasuke or Sakura. This could strengthen their bonds as they face new challenges together. He might also be more respected or feared by some of the villagers who were previously unaware of his connection with Kurama, which would add a new layer of complexity to his interactions within the village.
Well, it might lead to a different relationship with the villagers. If Naruto befriends Kurama early, he might not be as ostracized. Kurama could help Naruto show his power in a more controlled way, earning him respect rather than fear. This would change the whole dynamic of how Naruto grows up in the village and how he views himself and his place among the people.
The fact that Naruto already knows about Kurama makes it interesting because it subverts the normal storyline. Usually, Naruto gradually discovers things about Kurama, but here he starts with that knowledge, which can lead to a whole new set of adventures.
One possible plot development is that Naruto could start to explore the secrets of his clan. He might search for ancient techniques or artifacts related to his heritage.
Well, Naruto might gain new and powerful jutsu. Kurama could teach him some unique chakra control techniques that no one else in the village knows. This would make Naruto even more formidable in battle.
One possible plot development could be Naruto seeking out other Uzumaki descendants. He might want to learn more about his heritage from them.
In some 'naruto and kurama merge fanfiction', Naruto might gain new and extremely powerful abilities. For example, he could have enhanced physical strength and speed far beyond his normal limits. This merge could also lead to a new form of chakra control, allowing him to perform techniques that were previously impossible.
One possible plot development could be that Naruto becomes extremely powerful and is able to defeat enemies with ease. The new bloodlines might give him unique abilities like enhanced speed, strength, and elemental control. He could also face challenges as others might fear his newfound power.
One possibility is that Naruto's friends launch a rescue mission. They would use their unique skills, like Sasuke's Sharingan or Sakura's medical ninjutsu combined with her combat skills, to find and save Naruto.
Another aspect could be the reaction of the other characters in the Naruto universe. Some might be fearful of the new power, thinking the character with the transplanted Rinnegan could become a threat. Others might see it as an opportunity to use this new - found power for their own purposes, like fighting against a common enemy. There could be a lot of political intrigue and power struggles within the ninja villages as a result.
Perhaps Naruto's relationship with the other villagers changes more rapidly. In the original story, they were initially afraid of him because of Kurama. But with all of Kurama sealed in him from the start, they might be more in awe or more fearful, which could lead to different interactions. He might also have a different standing among the ninja in his village, being seen as a more immediate and powerful asset or threat, depending on how they view the power of Kurama.
