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.
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.
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.
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.
Sasuke could also be a main character. Even though he has his own path, his relationship with Naruto is so deep that he would surely be involved in Naruto's life as the Hokage. He might offer his support or advice when Naruto faces difficulties. And Kakashi, as Naruto's former teacher and the previous Hokage, could also be a key figure in the story.
I think the whole of Team 7 would be behind him. Sasuke, despite his past, would see Naruto's potential as a Hokage and support him in his own way, perhaps by helping to protect the village from external threats. Kakashi, as Naruto's former teacher, would also be there to guide him in the early days of his Hokage - ship.
I think the whole of Team 7 would be in full support. Sasuke might return to the village and support Naruto as he sees Naruto's growth and leadership potential. Kakashi would also be there to guide Naruto as he steps into the role. Additionally, the people of Konoha who have seen Naruto grow from an outcast to a hero would be very likely to support him as their new Hokage.
Well, if Naruto becomes the 5th Hokage in fanfiction, he would surely bring a new energy to the village. He might start by reforming the ninja training system. Since he had a tough time growing up as an outcast, he'd make sure no kid in the village ever feels that way. He could also focus on better relations with other villages. Naruto's always been about peace and friendship, so he'd probably organize more joint ninja missions with other villages to build trust.
Obviously Naruto is one of the most important. His strength and his ability to inspire others are crucial in the Fourth War setting. He's the one who can turn the tides with his positive attitude and powerful jutsu.
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.
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.
