It could be the very people who banished Naruto in the first place. They might fear his new - found power and try to stop him from returning to the village or from getting revenge. They would likely use underhanded tactics to try and take him down.
Maybe Naruto gets banished and ends up in a place full of ancient and powerful artifacts. He discovers how to use these artifacts to enhance his own abilities. He also forms alliances with some outcasts in this new place who share their combat skills with him. As a result, he becomes powerful not just in terms of his ninjutsu but also in terms of strategy and teamwork.
Well, one plot twist could be that Naruto discovers a hidden ancient power during his banishment. Maybe he finds a long - forgotten jutsu in a desolate place. Another could be that he forms unexpected alliances with former enemies who now see his banishment as unjust. For example, some of the minor villain clans might join him, seeing a chance to overthrow the existing power structure in the shinobi world.
Naruto's character could develop a more jaded side. After being banished, he might start to question the values he once held dear. However, his underlying kindness still remains. He becomes more cautious and calculating with his new power, not wanting to be used again.
He might meet other banished shinobi who have formed their own small community. They could teach him different techniques that are not known in Konoha.
One common theme is Naruto's struggle for acceptance. After being banished, he has to find a new place in the world where he can be himself and grow. Another theme could be revenge. He might seek revenge against those who banished him. And of course, power - building is a major theme. Naruto has to become powerful in his new situation, often in ways different from what he learned in the village.
In such a fanfiction, Naruto might gain unique sage powers that are different from the normal sage mode in the original series. He could use these powers to protect a hidden village of outcasts that he discovers during his banishment.
Well, perhaps Naruto is banished due to a false accusation. In his exile, he encounters a group of outcasts who follow the ways of the Onikage. They see Naruto's potential and offer him a place among them. Naruto at first is hesitant but as he gets to know their cause, which might be about protecting the forgotten and oppressed, he decides to embrace the role of the Onikage. He then uses his newfound power and influence to try and change the ninja world from the outside.
In such a fanfiction scenario, Naruto might bring a whole new style to being a Kage. He could use his out - of - the - box thinking and never - give - up attitude to reform the village in ways traditional Kages might not have considered. For example, he could focus more on rehabilitating rather than just punishing rogue ninjas, given his own experiences of being an outcast.
Well, if Naruto were banished and became Raikage in fanfiction, it would be a huge shift. He'd bring his own style of leadership. His experience in Konoha would influence how he runs the Hidden Cloud. Maybe he'd introduce new training methods like he learned from Jiraiya, and also promote more unity between the different ninja villages. He could also use his Nine - Tails chakra in unique ways to protect the Cloud Village.
