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 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.
Perhaps a perk is the ability to shape the future of the ninja world. As Hokage, one can inspire the younger generation of ninjas. They can create new ninja academies or training programs. They also have the power to pardon or punish ninjas according to their deeds, which helps in maintaining law and order in the village.
Sasuke could also be a possibility for the 6th Hokage in the fanfic. He has grown stronger over the years and his unique perspective on the ninja world could bring new ideas to the leadership of the Hidden Leaf. He might start off as a controversial choice but prove himself through his actions in protecting the village and making tough decisions.
Sasuke could be an alternative. He has strong ninja skills and a deep understanding of the ninja world. His experiences have made him grow into a very capable person, and his Sharingan gives him an edge in combat and strategic planning.
Well, it depends on the specific fanfiction. Some fanfictions might explore alternate storylines where Naruto doesn't become the Hokage at all. Maybe he decides to pursue a different path in life, like focusing on being a teacher or an explorer. However, in a large number of fanfictions, he does achieve his goal of becoming the Hokage because it's such an iconic and desired outcome for fans who want to see his journey to the top in different ways.
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.
Even Naruto himself could be a subject of this 'evil Hokage' concept in fanfiction. Maybe he is possessed by some dark entity or has a major change of heart due to some extreme event. This would completely change his character and turn him into an evil Hokage, which would be a very interesting and unexpected twist.
