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.
He may use his power as a ninja. Naruto is very powerful. He could directly challenge the council's authority if they were making decisions that were against the well - being of the village. However, this would be a more extreme measure and might cause some initial chaos in the village.
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.
In some versions, Snape uses his knowledge of the Dark Arts and Hogwarts' secrets. He might set up a situation where Umbridge is lured into a restricted area of the castle and gets into trouble with some magical creature or ancient magic, causing her to be removed from her position.
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.
In some fanfictions, Naruto might use his unexpected knowledge. For example, he could have learned about some ancient ninja tactics that the council overlooked. He then uses this knowledge to solve a problem or make a plan that the council couldn't come up with, thus outsmarting them.
He could use his Rasengan. If he manages to gather enough chakra secretly, he can surprise his captors with a powerful Rasengan and break free.
Well, in most cases, his friends would likely try to rescue him. Sasuke might put aside his differences for a while and join forces with Sakura and the others. They'd probably start by gathering information about the council's motives and the location where Naruto is being held.
Maybe he gets a better apartment through his newfound popularity as a hero. People in the village might recognize his efforts and contributions, so they offer him a nicer place to live.
If Naruto gets rid of Kurama in fanfiction, one way it could change the story is that Naruto would lose a major source of his power. He'd have to rely more on his own natural skills and training. This might make him seem more vulnerable at first, but it could also lead to him developing new and unique abilities. For example, he could focus more on his Sage Mode training and become even more proficient in it without Kurama's chakra interfering or overshadowing his progress.
Yes, in some fanfictions Naruto hates the civilian council. The civilian council often represents the more conservative and sometimes self - interested part of the village. They may oppose Naruto's ideas or actions out of fear or prejudice, which can lead to a situation where Naruto develops a dislike for them.
It could mean that the council in the Naruto universe is asking for fan - made fictional stories. Maybe they want to see different interpretations of the Naruto world from the fans.
