In addition to the main characters like Naruto, including the new generation of shinobi such as Boruto, Sarada, and Mitsuki would be great. They represent the future of Konoha and can have their own storylines within the fanfic. Shikamaru, as Naruto's advisor, is also a must - include character. His intelligence and strategic thinking can add a lot to the story.
There's an author named FireFan. Their fanfics are really popular. They are good at creating engaging stories that focus on the naruhina relationship within the context of Naruto being Hokage. Also, FrostyPen is great. They write fanfics that have a good mix of action and romance between Naruhina while Naruto is in his role as Hokage.
Iruka could be an interesting character to include. He has always been important in Naruto's life and could provide a different perspective on the Second Hokage's story. Hinata could also be part of it. Her gentle nature could contrast with the more battle - oriented characters. And Rock Lee, with his dedication to hard work and the ninja way, could be inspired by the Second Hokage's own determination and contribute to the story in his own unique way.
Kushina is an obvious choice. In fanfictions, they can have more adventures together, or their relationship can be explored in more depth. Their love story is already quite popular in the Naruto series, and in fanfictions, it can be expanded upon, like showing more of their courtship days.
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.
I really like 'Naruto: Hokage's Ascent'. It delves deep into the political aspects of being Hokage, which is not often explored in great detail in regular Naruto stories. It shows Naruto having to make tough decisions for the village, and the relationships between the different ninja clans are also well - portrayed.
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.
Shikamaru is another possibility. He is known for his strategic mind. As Hokage, he could use his intelligence to make wise decisions for the village. He may not have the brute strength of Naruto or Sasuke, but his ability to plan and analyze situations would be invaluable in leading Konoha.
I really like the fanfiction 'Hokage Naruto and Hinata's New Era'. In this story, Hinata uses her Byakugan abilities in unique ways to help Naruto in leading the village. It also delves into the family life of the Uzumaki family, showing their daily challenges and joys. The characterizations are really on point, making it a great read for any Naruto fan.
