The plot could also involve a time - related crisis. Maybe something is threatening the timeline, and the only way to fix it is for future Naruto to raise his younger self in a certain way. So, future Naruto has to make sure that the younger Naruto grows up to be strong enough to face this threat while also maintaining the integrity of the timeline.
Well, Naruto might be more confident in his relationships. Since future Naruto has given him insights, he could be more upfront with his friends. For example, he might be more open about his feelings towards Sakura and not be as bumbling. His friendships could also be deeper as he would have a better understanding of what true friendship means from future Naruto's teachings.
In a 'Naruto travel to the future fanfiction', Naruto would adapt through his strong sense of curiosity. He would be eager to explore every new thing he sees in the future. His resilience would also play a big role. If he encounters difficulties, like not understanding how a particular future - tech works, he won't give up. Instead, he'll keep trying until he figures it out. And his ninja training gives him discipline. He would use this discipline to study the new ways of life in the future, from the social norms to the technological advancements.
One possible scenario in this fanfiction could be that Naruto grows up with a more balanced upbringing. Tsunade might teach him medical ninjutsu and how to control his emotions better. Jiraiya, on the other hand, would surely train him in powerful combat techniques and in the ways of the sage. Naruto would probably be more mature and well - rounded at an earlier age, with a combination of Tsunade's tough love and Jiraiya's adventurous spirit guiding him.
One possible scenario in this fanfiction could be that Naruto grows up with the Namikaze Clan's unique jutsu training methods. He might inherit some of Minato's (a Namikaze) speed and intelligence in combat at a much earlier age. This could lead to him being a more confident and skilled ninja from the start, as the Namikaze Clan has a reputation for their strong abilities.
The Naruto world would be turned upside down. With Naruto being raised by Kaguya, his understanding of chakra and the ninja way would be completely different. He might introduce new forms of jutsu based on Kaguya's ancient knowledge. The balance of power among the ninja clans would be disrupted. His upbringing by Kaguya could also lead to a change in the social structure of the ninja villages. For example, he might promote a more hierarchical system similar to what Kaguya might have been used to, instead of the more democratic - ish system that was in place in the original story.
If Naruto was raised by the Straw Hats, he'd probably be a very different person. He might be more carefree like Luffy. For example, he'd be used to the wacky adventures on the Grand Line. His ninja skills could blend with the pirates' combat styles, creating some really unique fighting techniques.
Naruto would likely be more confident. With the Sannin as his guardians, he'd have access to top - notch training and knowledge. He might not have the same insecurities as in the original series. For example, Tsunade could help him with his self - esteem, Jiraiya with his understanding of the ninja world, and Orochimaru (in a reformed way) with his knowledge of forbidden jutsu, making him a more well - rounded and confident shinobi.
His relationship with Sasuke would likely be very different. Without the shared experiences in Konoha, their initial rivalry might not be as intense. Naruto might not be as desperate to bring Sasuke back. And his relationships with his other Konoha friends like Sakura and Kakashi would also change. He'd be more connected to Yugito's friends and allies instead.
He'd probably be more cautious. Quarians live in a fragile environment, and Naruto would grow up learning to be careful. So, instead of his usual head - on approach, he might think more before acting.
