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.
One possible fanfic could be about the 5th Hokage, Tsunade, facing a new and powerful enemy that the village has never seen before. This enemy could be a rogue ninja from a far - off land who has a special jutsu that can disrupt the chakra flow in the village. Tsunade would have to use her medical ninjutsu and combat skills to counter this threat and protect the village.
The fanfic might focus on the 6th Hokage's personal growth. He could start off with insecurities but as the story progresses, he overcomes them through various trials. For example, he might have to deal with a powerful rogue ninja who challenges his authority. In the process, he discovers new powers within himself and also learns more about the history of the ninja world. This growth not only makes him a better leader but also a more respected figure among the ninja community.
Naruto himself could be a likely candidate. Given his strength, leadership skills, and his dream of uniting the ninja world, he would make a great 6th Hokage.
In this fanfic, Naruto might bring new policies to the village. He could focus on improving the relations between different ninja clans. For example, he might create more joint training programs for the Uchiha and other clans to heal the old wounds.
Obviously, Naruto himself is the most important. But his friends like Sasuke would also play a significant role. Sasuke could be Naruto's right - hand man, helping him with security and intelligence matters in the village.
A plotline could be Tsunade trying to reform the medical ninja system in the village. There could be corruption or inefficiencies that she wants to address. This would involve her facing opposition from some of the established medical ninja families. She would have to use her authority as the Hokage to push through changes that would ultimately benefit the village in times of war and peace.
One popular '7th Hokage Time Travel Fanfic' is 'Naruto: Time Traveler's Redemption'. In this fanfic, Naruto travels back in time and uses his knowledge and skills to change the course of history. It has an interesting plot where he tries to prevent some of the tragedies that occurred in the original story.
Well, Naruto himself is likely to be there as he is an important part of the Naruto universe. Sakura might also be a common character. Since she has a long - standing relationship with Naruto and other characters in the series. Hinata could also be featured as she has her own connection to Naruto. These characters can be involved in the 'lemon' aspects, like perhaps a love story between the 6th Hokage and one of them.
Under Naruto as the 5th Hokage in fanfiction, the village would experience a cultural shift. Since Naruto values all kinds of people, the village would be more open to different ideas and ways of life. New forms of ninja techniques might be developed as he encourages everyone to explore their potential. Also, the village's defenses would be strengthened not just by physical means but also by the strong bonds between the villagers, which Naruto would foster.
