There could be a fanfiction where Orochimaru tries to redeem himself. He realizes the error of his ways after seeing the destruction he has caused. He might start to secretly help the Hidden Leaf Village against new threats, all while the villagers still see him as an enemy.
One interesting Orochimaru fanfiction could be about his early days of exploring forbidden jutsu. It might show how he got drawn into the dark side of ninjutsu research. Maybe he had a mentor who initially guided him in the right direction but then something happened that led him astray.
Another fanfiction could focus on Orochimaru's relationship with his former students. For example, how Sasuke's defection to him affected his view of himself. He might have moments of self - reflection, wondering if he is truly leading Sasuke down the right path or just using him for his own ends.
Another fanfiction might focus on Orochimaru's early days. It could explore his relationship with his sensei, how he got interested in forbidden jutsu in the first place, and what events led him to become the villain we know. For example, perhaps he was once a curious student who was pushed too far in his thirst for knowledge.
One interesting story could be about Naruto and Hinata going on a joint mission in the Shippuden era. They face a powerful enemy together and through their teamwork, they not only defeat the foe but also deepen their bond. Hinata might use her Byakugan in a unique way to support Naruto during the fight.
Fanfiction.net is a great place to start. It has a large collection of Naruto - related fanfictions, including many focused on Orochimaru. You can search by the Naruto Shippuden tag and then narrow it down to Orochimaru - centered stories.
A really cool plot might be that Orochimaru discovers a prophecy about Naruto being the key to a new era of ninjutsu. Instead of trying to take over Naruto's body, he decides to team up with Naruto. They go on a journey to find ancient scrolls that can unlock this new era. Along the way, they face many challenges and their relationship evolves from mistrust to a strange kind of friendship. Another plot could be that Orochimaru is resurrected after his death in a different form and has no memories of his past evil deeds. Naruto is the one who finds him and decides to help him start a new life, but they have to face the people who still remember Orochimaru's old self.
In some fanfictions, Orochimaru could be a mentor figure to Naruto in a different sense. He might teach Naruto some dark jutsu not to use them for evil but to understand the nature of power better. Naruto, in turn, could teach Orochimaru about friendship and redemption. But of course, this is all part of the creative world of fanfiction.
Well, in some Naruto Shippuden extreme fanfiction, there are storylines that explore romantic relationships in more depth. For example, a story could be about Hinata's journey to become stronger not just for herself but also to be a better partner for Naruto. Or perhaps a fanfic where Sakura discovers a new medical ninjutsu that has the power to change the outcome of major battles, and how that affects her relationships with her comrades. There are also those that focus on the Akatsuki members' pasts and how they could have been redeemed.
Well, in 'naruto shippuden training fanfiction', the relationships between characters can be explored in a new light during training. Like Sasuke and Naruto's rivalry might be intensified or mended during a shared training session. Also, the fanfiction might introduce new training locations, such as a hidden dimension full of dangerous creatures that the characters have to overcome to gain power.
One idea could be to rewrite the story from the perspective of a minor character. For example, seeing the events through the eyes of a regular shinobi in Konoha who is not part of the main cast. This would give a fresh view on how the big events impact the everyday life of the village. Another idea is to change the power dynamics. Maybe make some of the weaker characters have a unique power - up that makes them more relevant in the battles. You could also rewrite the story to focus more on the political intrigue between the different villages, showing how the ninja world is affected by power struggles at a higher level.
One interesting concept could be an OC who is a long - lost relative of a major character, like a cousin of Naruto. This OC could have a unique chakra ability that they discover during their journey. Another idea is an OC from a different hidden village who comes to Konoha as an exchange student and has to adapt to the new environment while also hiding a secret mission.
One interesting plotline could be Orochimaru trying to use Naruto for a new experiment but Naruto ends up influencing Orochimaru instead. For example, Naruto's strong will and belief in friendship might start to make Orochimaru question his own dark path.
