In 'naruto s class missing nin fanfiction', the theme of identity is quite prominent. These S - class missing - nins struggle with who they are, whether they are truly evil or just misjudged. Another common theme is loyalty. Some stories explore if they can still have loyalty to their former villages or comrades. And the theme of revenge also appears sometimes, where an S - class missing - nin seeks revenge for something that happened to them in the past.
One common theme is redemption. Since Naruto is a missing nin, often the stories explore his path to redeem himself while building his harem. Another theme is power. His new status as a missing nin might give him different powers or ways to use his existing powers in the context of the harem.
Isolation is a common theme. Since they are missing - nins, they are often alone and have to fend for themselves. Another theme is redemption. Many of these fanfics explore the idea of the missing nin trying to make up for their past mistakes.
Power and growth are also frequent themes. Away from her normal support system, Sakura has to develop new skills and become stronger. For instance, she might learn new jutsu or develop better combat strategies. It's about her evolving into a more formidable and self - reliant character.
Power and isolation. Naruto being SSS rank makes him extremely powerful, but as a missing nin, he is isolated from his former village and friends. This creates a theme of loneliness and the struggle to find a new place in the world.
One common plotline is that they team up against a new, greater threat that neither the Hidden Leaf nor any other village can handle alone. Since they are missing - nin, they have more freedom to operate outside the normal shinobi rules. Another plotline could be their journey to discover the truth about the shinobi world and the secrets that were hidden from them when they were part of their respective villages. They might also encounter other missing - nin and form a sort of alliance with them, either for mutual protection or to achieve a common goal like overthrowing a corrupt system in the shinobi world.
A really cool 'naruto s class missing nin fanfiction' is 'Rebel S - Class'. It's about an S - class missing - nin who rebels against the traditional ninja ways. They form their own group and start to change the power dynamics in the Naruto world. The story is full of action and interesting character developments. Another one is 'S - Class Unleashed' where the S - class missing - nin reveals their true and extremely powerful abilities, causing chaos and also a new form of order in the Naruto world.
One idea could be exploring the backstory of an S - class missing - nin. Maybe they had a noble reason to turn their back on the village at first, like trying to protect a loved one from a corrupt system within the village.
Perhaps the missing nin discovers new abilities within the Rinnegan that no one else has. They might be able to combine different paths in unexpected ways. For instance, using the Animal Path to summon creatures and then enhancing those creatures with the power of the Asura Path. This would make their summoned beasts more powerful and difficult to defeat in combat.
If Naruto and Temari were missing nin in a fanfiction, it could start with a misunderstanding. Naruto might be framed for a crime he didn't commit and Temari, believing in his innocence, decides to help him escape. They then have to live on the run. Along the way, they meet other outcasts and form a sort of rebel group. Naruto's ability to make friends easily and Temari's strong leadership skills could be the driving force behind this new group's growth.
Kimimaro could be an interesting missing nin character to explore in fanfiction. He was a tool for Orochimaru, but had his own internal struggles. You could write about his life before fully becoming a missing nin, his loyalty to Orochimaru despite his own deteriorating health, and what might have happened if he had broken free from Orochimaru's control. Another character could be Nagato. Before he became Pain, he had experiences that could be considered as leading towards a missing - nin - like existence. His views on peace and his use of the Akatsuki could be delved into in the context of a missing nin story.
