One key character could be an outsider who Naruto meets after being banished. This person could be a powerful ninja from another land who takes Naruto under their wing. Also, the elders of the village who hold sway over the council would be important. Their reasons for wanting Naruto gone could be a central part of the mystery in the fanfiction. And Hinata might be a character who secretly tries to help Naruto from within the village.
The council members themselves would be key characters. They are the ones making the decision to banish Naruto. Also, characters like Iruka sensei could play an important role. He might be torn between his loyalty to the village and his belief in Naruto. Another could be Sasuke. He might react in different ways, either trying to help Naruto or seeing it as an opportunity to prove his own superiority.
Definitely the Hokage at the time would be a crucial character. Whether they support the council's decision or try to oppose it would greatly affect the story. Then there are Naruto's friends like Shikamaru. He might use his intelligence to try and figure out a way to get Naruto back. And Kakashi sensei could also be important. He has a connection with Naruto and might try to understand the council's motives better.
Hinata could also be a common character. She may try to help Naruto secretly, or be heartbroken by his banishment and strive to change the village's decision. Another character could be Kakashi. He might be one of the few who believe in Naruto's innocence and try to find a way to bring him back to the village.
In this type of fanfiction, the plot might involve Naruto being exiled due to the council's fear of his growing power. They may see him as a threat to the established order in the village. Naruto, being banished, could then go on a journey to become even stronger outside the village, perhaps finding new allies and learning unique jutsu.
Sasuke is often a common character. He might have a different reaction to Naruto's banishment compared to the original story. Maybe he decides to join Naruto outside of Konoha or tries to find a way to get him back. Kakashi could also be there. He might be conflicted about Naruto's banishment and could play a role in either helping Naruto secretly or trying to uphold Konoha's decision.
Sasuke would likely be involved. He has his own issues with Konoha and might side with Naruto, either out of friendship or his own vendetta against the village. Also, the elders of Konoha like Danzo could be important characters as they might be the ones behind Naruto's banishment.
Sasuke could definitely be one. He might be conflicted about Naruto's banishment, either thinking Naruto deserved it at first and then changing his mind, or trying to find a way to bring Naruto back. Kakashi could also be in it. He might be one of the few in the village who believe in Naruto's innocence and try to secretly help him.
Obviously, Naruto would be one of the key characters. He's the main protagonist and his opinions often matter a great deal in the village. Also, Shikamaru, with his high intelligence, might be present and play an important role in the discussions.
In such a fanfiction scenario, Naruto might end up seeking a new life elsewhere. He could join a different ninja village or perhaps go into hiding and train in solitude. He might also try to find allies outside the village who would believe in him and his potential.
Bulbasaur - girl might be a great choice too. Her connection with nature and plant - based attacks could add an interesting dynamic. She could help Naruto understand the Pokemon world better, especially when it comes to things like finding herbs or dealing with forest - related challenges. There could also be a fiery - tempered Charmander - girl who provides a contrast to Naruto's more easy - going nature and has her own set of powerful fire - type attacks.
Obviously, Naruto is the key character. He's the one taking on the council. But there could also be other characters like Kakashi, who might support Naruto in his endeavor.
Maybe some local tribespeople who have unique abilities or knowledge. For example, they could teach Naruto some ancient techniques or survival skills that are not known in the Hidden Leaf Village. There might also be wandering samurai or other shinobi from different regions who pass by the outpost and interact with Naruto.
