What could be the possible plot if Naruto becomes a nukenin in fanfiction?

Perhaps Naruto becomes a nukenin in order to protect a secret that could endanger the village if it were to be exposed. He leaves the village to keep this secret away from those who might misuse it. In his journey as a nukenin, he could develop new jutsu in isolation, away from the constraints of the village's training methods.

If Naruto becomes a nukenin, his relationship with the village elders would be completely severed. They would see him as a threat, and he would see them as unjust. With his peers, some might side with him, believing in his innocence. Others would follow the village's orders out of loyalty. His bond with the Nine - Tails would also change. The Nine - Tails might offer more support, seeing Naruto as an outcast like itself.

One idea could be exploring the backstories of the nukenin in more detail. Maybe they had noble reasons for leaving their villages that were misinterpreted.

With his friends in Konoha, like Sakura and Kakashi, there would be a major shift. Sakura might initially be conflicted between her loyalty to the village and her friendship with Naruto. Kakashi, being a more experienced shinobi, might understand Naruto's reasons better but still be bound by his duties to the village. Overall, Naruto's departure as a nukenin would create a lot of emotional turmoil among his relationships.

A plot twist might be that Naruto discovers that being a monk is actually a key to unlocking a hidden power within him that has nothing to do with chakra. This new power could be related to his spiritual enlightenment and could change the balance of power in the Naruto universe in the fanfiction. Another twist could be that his friends, believing he has abandoned them, turn against him at first, but then later realize that his new path is actually for a greater good and they end up joining him in some way.

One possible plot development could be Naruto struggling to control his new dragon powers. He might accidentally cause destruction in the Hidden Leaf Village at first. Then, he'd have to go on a journey to learn how to master these powers, perhaps with the help of an old sage or a mysterious dragon - like creature.

In this fanfiction, Naruto's death could be a sacrifice. As a hollow, he could start off being very confused. His ninja skills might be warped in this new form. For example, his Rasengan could turn into some sort of dark energy blast. He might also meet other characters from the Naruto world who have also had strange after - deaths, and together they try to find a way to either move on or return to their normal state.

Well, one possibility is that Naruto feels betrayed by the Hidden Leaf Village. Maybe they wrongly accused him of a serious crime. So, he decides to go rogue. He could then start traveling alone, using his skills to survive and avoid capture. He might also meet other outcasts who understand his situation.

In a 'naruto becomes a missing nin fanfiction', perhaps Naruto discovers some dark secrets about the village leadership. These secrets are so dangerous that the village wants to silence him. He then decides to go rogue to expose these secrets to the world. As a missing nin, he might form alliances with other outcasts who also have a grudge against the current system.

In this fanfiction, perhaps Naruto's physical abilities are enhanced as the Kyuubi's kit. He might be able to move faster, jump higher, and his strength could be superhuman. Also, his relationship with Sasuke could change. Sasuke might see Naruto as an even greater threat or, on the other hand, an ally he needs to understand better. And Naruto could start to have a different understanding of his own identity and place in the ninja world.
