There are several characters who could support Naruto in such a fanfiction. The Inuzuka clan might side with him, as they respect strength and Naruto has proven himself time and again. Shikamaru, being Naruto's friend and a smart strategist, would definitely offer his support. And perhaps some of the jonin who believe in Naruto's ideals and think the council is overstepping its bounds would also back him up in this fight.
I think some of the younger ninjas in the village would support Naruto. They look up to him as a role model. Also, those who have been helped by Naruto in the past, like the families of the villagers he saved. They would see that Naruto is fighting for what's right and would stand with him against the council. Additionally, some of the outcast ninjas who feel oppressed by the council's rules might also join Naruto.
In this kind of fanfiction, Naruto might face a tough battle against the council. Maybe he's fighting for his own beliefs or to protect his friends. He could use his signature jutsus like the Rasengan to take on the council members who may have their own political motives and powerful techniques.
One possible plotline could be that Naruto discovers some underhanded schemes the council has been planning against him. Maybe they are trying to limit his growth as a ninja because they fear his power. So, Naruto decides to fight back by gathering evidence of their wrongdoings and presenting it to the village elders who are not part of the corrupt council. This would be a way for him to expose them and regain the trust and freedom he deserves.
His friends like Sasuke could be his allies. Sasuke, despite his own complex journey, has a deep connection with Naruto. He would understand Naruto's need to fight against the council if they were being unjust. Also, Sakura, with her medical skills and growing strength as a ninja, would be a great asset. She could heal the team during any confrontations and also use her combat skills when necessary.
One possible reason could be that the council often restricts Naruto's actions. They might see him as a potential threat or a wild card due to his Nine - Tails power. So, Naruto, being a free - spirited person, would naturally hate being controlled by them.
Naruto could also show his hatred through his actions. Maybe he refuses to cooperate with any mission or task that is directly related to the council's orders. He would rather do things his own way or follow the orders of someone he trusts more, like Kakashi or Iruka.
He might use his influence as a hero. Naruto has a lot of friends and supporters in the village. By getting them to see his point of view about the council's inefficiencies or wrongdoings, he could start a movement to oust the council. For example, he could talk to his old friends like Shikamaru, who is intelligent and might be able to come up with a strategic plan.
On the positive side, new and better policies could be implemented. If the old council was corrupt or stagnant, getting rid of them would open the door for fresh ideas and reforms. Naruto could bring in new people with different perspectives to help run the village, leading to a more prosperous and fair Konoha.
Well, in this kind of fanfiction, Naruto might snap at the council because he's tired of their unfair treatment. Maybe they keep underestimating him or trying to control his actions. For example, they could be restricting his ninja training or missions in a way that he finds unjust.
Maybe they lack fresh ideas themselves and hope to get inspiration from fanfiction.
One reason could be that they want to enlist Naruto's help for a particular mission. Since he has unique abilities as a jinchuriki and has proven himself in many battles, they may think he's the best person for the job. Also, they might call him to clarify some misunderstandings. There could be rumors or false information about Naruto circulating in the village, and the council wants to get the truth from him directly.
