His friends like Sakura and Shikamaru would surely support him. Sakura, with her medical skills, could be an important part of his regime, providing healthcare for the ninjas. Shikamaru, being intelligent, could offer strategic advice. Also, the younger generation of ninjas who have been inspired by Naruto would be his strong supporters, as they believe in his leadership and the new direction he could take the village in.
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.
If Naruto is the fifth Hokage in the fanfiction, the village would likely experience a lot of positive changes. Naruto has always been about friendship and believing in others. As Hokage, he'd promote this ideology throughout the village. He might encourage more cooperation between different ninja clans, breaking down old rivalries. He could also invest more in village defenses, not just in terms of physical barriers but also in intelligence - gathering. And of course, he'd be a great source of motivation for the younger ninjas, who would strive to be like him.
A good 'Naruto Fifth Hokage fanfiction' should have a strong characterization of the Fifth Hokage. It should capture her essence, her strengths, and her insecurities. For example, if it's Tsunade, her fear of blood and how she overcomes it in different situations can be a great aspect to explore.
One great 'Naruto Fifth Hokage fanfiction' could be one where it focuses on the Fifth Hokage's early days in the position. Maybe it shows how she had to deal with the distrust from some of the village elders who thought she was too young or inexperienced. Another aspect could be her training of the new generation of ninjas, like how she passed on her unique skills to them.
Sakura could be really interesting. As a highly skilled medic - ninja, she could play a crucial role in supporting Naruto as the Fifth Hokage. Maybe she has to deal with a new disease outbreak in the village and has to find a cure while Naruto is handling other threats. Kakashi could also be fascinating. He has a wealth of experience and could act as an advisor to Naruto. He might have some old - fashioned ideas that Naruto has to balance with his own more modern approach.
Another aspect to explore in the fanfic is Naruto Senju's relationship with the other villages. Given his Senju heritage, there might be different expectations and tensions. He could work towards a more equal - footed relationship with other villages, instead of the traditional power dynamics. This would involve a lot of diplomatic meetings and negotiations, which could be full of drama and intrigue.
He would become more responsible. As Hokage, he has to think about the whole village, not just his friends. So he might be a bit more serious, but still keep his positive and energetic side.
The other ninja clans' leaders would be important characters too. For instance, the Uchiha clan leader (if the story is set at a time when the Uchiha were still in the village) could play a role in the power dynamics related to the fifth Hokage. And of course, the Hokage's personal friends and mentors from their younger days.
One possible plot could be Naruto having to prove himself to the village elders. He might start by implementing new training programs for the younger ninjas, inspired by his own journey. He could also focus on improving relations with other villages, using his charisma and unique perspective as someone who was once an outcast.
