Perhaps Naruto becomes a vigilante after being wrongly accused of a crime he didn't commit. As a result, he goes into hiding and starts operating from the shadows. He could then use his skills and knowledge to not only clear his name but also expose the real culprits behind the false accusations and other corrupt elements in the ninja world.
Another storyline could be that Naruto is wrongly accused of a crime he didn't commit in Konoha. Disillusioned with the village that once supported him, he becomes a ronin. He then meets other outcasts along his journey who have similar stories. Together, they form a sort of vigilante group that helps those who are oppressed by unjust ninja villages.
One possible storyline could be that Naruto is betrayed by those he trusts most in the village. This heartbreak and sense of abandonment could lead him down a dark path. He might start to question the values he was taught and use his power in more self - serving and ruthless ways.
His powers might be more understated as a vigilante. Instead of using his flashy jutsus openly, he could develop more stealth - based techniques. For example, he might modify his Rasengan to be a silent and more deadly attack for surprise attacks on criminals.
One possible storyline could be Link trying to adapt to the Gerudo way of life. He might struggle with their traditions and customs at first but gradually learn to embrace them. Another could be Link using his skills as a hero to help the Gerudo in some great crisis, all while being a male in their female - dominated society.
One possible storyline could be Percy suddenly finding himself with Jack Frost's powers. He might struggle to control them at first, like when Jack first got his powers. For example, he could accidentally freeze things or create snowstorms when he doesn't mean to.
Well, if Harry becomes a vigilante, he would probably form his own group of like - minded wizards. They could work together to fight against the dark forces that are being overlooked by the authorities. He may also develop new spells or magical techniques that are specifically designed for his vigilante activities. And his friends, like Hermione and Ron, would either support him wholeheartedly or try to persuade him to work within the system, which could lead to some interesting character dynamics.
A storyline could involve Naruto using his newfound Nara abilities to solve a mystery in the village. Maybe there's a strange phenomenon that's related to shadow - based jutsu, and Naruto, with his understanding of both Uzumaki and Nara powers, is the only one who can figure it out. He'd have to team up with other characters, and in the process, there would be a lot of character development and interesting interactions.
Another storyline might be that Millet is a secret organization in the Naruto world. Naruto discovers that this organization has been pulling the strings behind some of the conflicts. He has to infiltrate it and expose their true motives. This would be a great opportunity for Naruto to use his stealth and combat skills, as well as his ability to make friends and allies within the organization to bring it down from the inside.
One possible storyline could be that Naruto is chosen as a temporary Kazekage due to a threat that requires his unique skills. He then has to deal with internal conflicts within the Sand village while also facing external enemies. Another could be that there is some kind of prophecy that only Naruto can fulfill as Kazekage to save both Konoha and Suna.
One possible storyline could be Naruto as an elf trying to fit into the ninja world while still having his elf heritage. He might face discrimination from some who don't understand his different nature.
