Perhaps Naruto meets some outcast ninjas in the Cloud village who have similar experiences to him. They form a kind of alliance. Together, they try to change the situation in the Cloud village and also work towards Naruto's return to Konoha. They might face a lot of difficulties and challenges from the traditional forces in the Cloud village.
One important character he could meet is the Raikage. The Raikage might initially be hostile towards Naruto due to his being from Konoha, but later sees his potential. Another could be Killer Bee. Maybe Killer Bee becomes Naruto's mentor in some ways, teaching him about the power of the tailed beasts in the Cloud village's perspective.
Well, one possibility could be that Naruto in the fanfic has to face a lot of discrimination in the Cloud village at first. But then, he gradually shows his strength and unique charm, making some friends who help him grow stronger. Maybe he also discovers some secrets about the Cloud village that are related to Konoha.
Obviously Naruto is one of the main characters. He is the center of the story as he is the one exiled from Konoha.
Iruka could also be important. Since he was one of the few people who showed some kindness to Naruto in the original story. He might feel guilty about Naruto leaving due to neglect and set out to find him. His presence could add an element of emotional depth to the story as he tries to make amends.
In many 'Naruto Exiled from Konoha' fanfictions, the Akatsuki members could be involved. They might view Naruto as a valuable asset now that he's an outcast from Konoha. Naruto could either befriend some of them, like Pain, who sees Naruto's potential and decides to help him in his exile, or he could be constantly on the run from them as they try to capture him for their own purposes.
Maybe Naruto would meet some young Uzumaki clan members who look up to him. They would be inspired by his strength and his will to protect the village. Naruto could then take on the role of a mentor, teaching them the values he learned in Konoha and also some of his own ninja techniques.
Another plot might be Naruto's journey of self - discovery during his exile. He could be exploring new jutsus and powers that he didn't have the chance to in Konoha. For example, he might discover a hidden power within himself that is related to an ancient ninja clan. This could lead to him becoming much stronger and more confident.
One reason could be false accusations. Maybe some powerful individuals in Konoha frame Naruto for a serious crime he didn't commit. For example, they could plant evidence that he was involved in a plot against the village leaders. Another reason might be the fear of his power. If his strength grows too rapidly and uncontrollably in the fanfiction, the elders or some conservative forces in Konoha may decide to exile him to prevent any potential disasters. Also, political intrigue could play a part. If there are different factions vying for power in Konoha and Naruto becomes an obstacle or a scapegoat for one of them, they could manipulate the situation to get him exiled.
One possible reason could be that he is wrongly accused of a serious crime against the village. For example, if some important secrets are leaked and the village leaders suspect Naruto without proper investigation, they might exile him to safeguard the village's so - called security.
One possible reason could be political intrigue. Maybe there are some within Konoha who fear the power she might possess as a female Jinchuriki. They could spread false rumors about her being a threat to the village's stability, leading to her exile.
The important characters would start with Naruto. Then, any of the other Jinchuuriki that the author decides to include. For example, if the story is set in a certain time period, we might see the Jinchuuriki from Naruto's generation more prominently. So, characters like Gaara and Killer Bee would be very important. And there could be some new or less - known Jinchuuriki introduced to add more depth and variety to the story.
