One idea could be the Nanadaime Hokage (Seventh Hokage Naruto) traveling back in time to his younger self's era. He could use his knowledge of future events to prevent certain tragedies, like the death of some of his comrades. Maybe he could change the way he approached his training, leading to even greater power earlier on.
His relationship with his teachers would also change. For example, with Iruka - sensei, Naruto could show his gratitude in a more profound way. He could also use his skills as the Seventh Hokage to help Iruka in ways he couldn't before. And with Kakashi - sensei, Naruto could offer insights into future threats and how to better train the next generation, strengthening their bond as teacher and student even more.
One common theme is redemption. The Nanadaime Naruto often goes back in time to correct past mistakes or save characters who died. For example, he might try to save his sensei, Jiraiya.
Another idea is that Naruto in his role as the Seventh Hokage is transported to a world where ninjas are extinct, but there are other super - powered beings. He has to find a way to prove the value of the ninja way and also learn from these new beings to bring back what he has learned to his own world.
One popular 'naruto nanadaime time travel fanfiction' is 'Naruto: Back to the Beginning' where Naruto travels back in time and uses his knowledge to change things. It has an interesting take on how his future skills impact the past.
One great 'Naruto Hokage Time Travel Fanfiction' is 'A New Beginning'. It has an interesting plot where Naruto travels back in time and uses his knowledge to change many things in the ninja world. The character development is really well - done, especially how Naruto becomes more cautious and strategic with his second chance at life.
Another possibility is Naruto traveling back to his own childhood days. He could mentor his younger self, teaching him advanced jutsu and wisdom he's gained over the years. This would make his younger self much stronger much earlier, and might also change how he interacts with Sasuke. For example, he could help his younger self better understand Sasuke's pain and prevent some of their earlier conflicts.
Another idea for this fanfiction is that Naruto's time travel as the 6th Hokage could lead to him meeting his predecessors in a different way. He could learn new jutsu or leadership skills directly from them. For instance, he could have in - depth conversations with the 1st Hokage, Hashirama, about how to better manage the relationships between different ninja clans and build a stronger, more united village.
The idea of time travel in 'Naruto Hokage Time Travel Fanfiction' is appealing because it allows for a lot of 'what - if' scenarios. Fans can see how Naruto, as a Hokage, would change things if given a second chance. It's a chance to rewrite the story in a more ideal way.
If Naruto changes something major in the past, it could disrupt the timeline. For example, if he prevents the Uchiha massacre, Sasuke's path would be completely different. He might not have the same drive for revenge, which could mean he doesn't leave Konoha. This would change Naruto's own growth as a ninja, as Sasuke was a big part of his motivation to get stronger.
