In this kind of fanfiction scenario, Naruto could potentially change a lot of things. He might use his knowledge of future events to prevent certain tragedies. For example, he could try to save his parents or prevent the destruction of the village by Orochimaru earlier. He could also train his younger self more effectively, sharing all the skills he has learned over the years.
Well, Naruto's relationship with the villagers would be quite different. Instead of being the outcast he was as a child, he could use his knowledge of the future to show his worth early on. This might lead to more positive interactions with the villagers. And his relationship with his friends like Shikamaru and Choji could also be enhanced as he could introduce more interesting things to them at an earlier stage.
He might start with basic physical training. You know, like running up mountains or doing a lot of push - ups to build strength. Also, chakra control exercises would be key. He could teach his younger self to focus chakra on different parts of the body for more effective jutsu use.
Well, it could have a huge impact. Naruto, being more experienced, can teach his younger self new jutsus. He might also instill in him a stronger sense of self - belief. For example, he could show his younger self how to better control the chakra of the Nine - Tails. This would make his younger self more confident in battle and in dealing with the village's expectations.
Well, Naruto could also mentor his younger self about the importance of friendship. He's had so many experiences with his friends like Sasuke and Sakura. He might tell his younger self not to take their relationships for granted and how they all contribute to his growth as a ninja.
In a fanfiction scenario where Naruto meets his younger self, it would be a very unique situation. Naruto might show his younger self some of the new jutsus he's mastered, like the Rasengan variations. His younger self would be eager to learn from him. Also, Naruto could talk to his younger self about his dreams and how he's still holding on to them, even after all the difficulties. This meeting could potentially change the course of his younger self's life, as he could be more determined to reach his goals faster with the knowledge of his future self.
In this kind of fanfiction, it could lead to some really interesting power dynamics. Naruto might gain new abilities or have a different understanding of his powers at a younger age. Maybe he could use the power of the Juubi to protect the village in ways he couldn't before in the original story.
If Naruto is sealed in his younger self in a fanfic, it could be chaotic. His chakra control might go haywire as his younger body tries to adapt to the sealed future self. The village elders might notice something strange and try to investigate. His training with Iruka Sensei could take a whole new turn as he might show advanced skills too early. This could also have an impact on the Nine - Tails within him. The Nine - Tails might react differently to this new situation, perhaps becoming more or less aggressive depending on how the seal affects Naruto's mental state.
One aspect could be Naruto training his younger self to be a better shinobi. He'd share his battle experiences, like the fights against Haku and Zabuza. His younger self would learn from his future self's strategies and become a more formidable ninja at a younger age. Also, Naruto could help his younger self understand the power of the Nine - Tails in a more positive way, instead of just seeing it as a curse. This could lead to his younger self being more confident and in control of his abilities much sooner.
In this fanfic, Naruto might teach his younger self some advanced jutsu. For example, he could show the younger Naruto how to better control the chakra for Rasengan at an earlier stage. This would make the younger Naruto stronger faster in the story.
