One possible plot could be that Naruto and Sasuke are wrongly accused of a serious crime against Konoha. For example, they might be framed for conspiring with an enemy village. As a result, they are banished. Naruto, with his unwavering spirit, might start thinking about how to prove their innocence from outside the village. Sasuke, on the other hand, could initially be more bitter and focused on getting revenge on those who framed them. Together, they embark on a journey to find the real culprits while also facing various challenges outside Konoha, such as dealing with other ninja clans who see them as outcasts and potential threats.
In a 'Naruto and Sasuke banished from Konoha' fanfic, the plot could revolve around a power struggle within Konoha. Maybe there's a group within the village who see Naruto and Sasuke as threats to their own rise to power. So, they manage to manipulate the situation and get them banished. Naruto and Sasuke then have to find a new place to call home. They might meet new allies, like some small ninja villages that are also at odds with Konoha. And they start building their own power base, with Naruto's charisma and Sasuke's strength, all while still having a longing to clear their names and return to Konoha one day.
Perhaps Danzo could be the main antagonist. He was always a bit of a shadowy figure in the original Naruto series. In this fanfic, he might see Naruto and Sasuke as a threat to his own control over Konoha. So, he uses his influence to have them banished. He could be secretly working with external forces to further his own agenda while keeping Naruto and Sasuke away from Konoha.
Well, the plot could involve Naruto being wrongly accused of something major, leading to his banishment. With his newfound ability of Wood Release, perhaps he teams up with some outcasts. He might use the Wood Release to create a new home for himself and his new allies, and then seek to prove his innocence to Konoha while also protecting his new place from any threats.
Perhaps Naruto discovers a long - hidden secret about Konoha that led to his banishment. This could involve some dark deeds in the village's past that certain individuals were trying to cover up by getting rid of Naruto. He then uses this knowledge to his advantage in some way.
In this kind of fanfiction, Naruto might be banished due to some false accusations or political conspiracies in Konoha. Once banished, he could decide to destroy Konoha out of anger and a sense of betrayal. He may have learned powerful jutsus during his exile and use them against the village that once rejected him.
One possible reason could be false accusations of a serious crime. For example, if he was wrongly blamed for a major attack on the village. Another reason might be political intrigue. Some powerful figures in the village might see Naruto as a threat to their power and find a way to banish him to maintain their control.
One possible reason could be fear. Naruto's 'godlike' powers might be too much for the village to handle. They could be afraid that he might accidentally cause destruction. Another reason might be envy among some of the villagers or ninja. They may not like that Naruto has become so powerful all of a sudden and want him out of the way.
Maybe a group of rogue ninjas who initially see Naruto as a target but then end up joining forces with him. They have different skills and personalities that add to the story.
In fanfiction, it could be due to a new threat that Konoha refuses to take seriously. Suppose there's a new and extremely dangerous enemy on the rise, and Konoha's leadership decides to ignore it or handle it in a way Naruto and Sasuke don't agree with. They might then choose to leave Konoha to face this threat on their own terms, believing that they can't do it while being restricted by Konoha's rules.
One possible ally could be Yamato. He has knowledge of the Wood Release and could help Naruto better understand and control his new power. Shikamaru might also become an ally. He is smart enough to see through the false accusations against Naruto. And there are the Akatsuki members who might have a change of heart. For example, Itachi's spirit could guide Naruto in some way, or Kisame could see Naruto's potential and side with him.
It could be a hidden group within Konoha that was behind Naruto's banishment. They might be afraid of his growing power and influence. This group could work in the shadows to stop Naruto from ever returning to Konoha and regaining his status.
