The training would likely accelerate his younger self's growth. Older Naruto has faced many challenges and learned from them. He can pass on valuable combat strategies and survival skills. Maybe he teaches his younger self how to anticipate an enemy's moves better. This would give his younger self an edge in future battles and help him mature faster as a ninja.
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.
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.
The training could speed up the younger Naruto's growth. He would become stronger and more skilled faster, which might lead to different outcomes in battles. For instance, he could defeat enemies more quickly and with less damage to himself and the village.
The story might progress with the older Naruto taking the younger one on special training missions. They could go to places that the younger Naruto has never been before, like some hidden training grounds in the outskirts of Konoha.
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.
One possible thing that could happen is that Naruto could teach his younger self some advanced jutsu. For example, he might show the younger Naruto how to better control the Nine - Tails' chakra earlier. This would give the younger Naruto a significant power boost and change the way he approaches battles in his early days.
In fanfiction, this concept would have a huge impact. Naruto's growth would be different. He would have to deal with the power of the Juubi at a time when he is still developing his own identity. This could lead to a different Naruto, one who is more mature in some ways and yet still retains his naivete in others. The story could also explore how the village and its people react to this new Naruto. Some might fear him, while others might see him as a new hope. And in battles, Naruto could potentially defeat enemies much quicker, which would change the overall plot of the Naruto universe in fanfiction.
He'd become more patient. Naruto was always a bit impulsive when he was younger, but having to raise his younger self, he'd have to learn patience. He can't just rush into things like he used to. He'd also be more nurturing. Since he's taking on a parental - like role, he'd be more caring and gentle with his younger self, which is a change from his usually rambunctious self.
Naruto might be more solemn. He has seen the darker side of the ninja world, and when mentoring his younger self, he would carry that weight. He would still have his upbeat side, but there would be a newfound seriousness in his mentoring, like when he warns his younger self about the real dangers of the Akatsuki.
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.
His older self might become more nostalgic. Meeting his younger self would remind him of his more innocent days. He could become a bit more carefree again, like he was when he was younger.
