A plot could involve Orochimaru using his knowledge to help Naruto unlock a new power, but in the process, they get closer than expected. As they train together, their interactions become more intense and personal. Naruto's positive influence gradually changes Orochimaru's view of the world, and they end up on a journey together to face a common enemy that only their combined skills can defeat.
One interesting idea could be Orochimaru seeing Naruto as a unique specimen and instead of just trying to use him, he actually starts to respect Naruto's willpower. This could lead to a strange mentorship of sorts where Orochimaru teaches Naruto some of his more unorthodox jutsu in exchange for Naruto trying to help Orochimaru find a new path that doesn't involve so much darkness.
One idea could be Orochimaru seeking redemption through Naruto. Naruto, with his belief in the goodness of people, tries to reform Orochimaru. Another could be Orochimaru becoming an unlikely ally to Naruto in a fight against a greater evil, like a new powerful enemy that threatens the entire ninja world.
One idea could be Orochimaru taking an unexpected interest in Naruto's growth not for his power but for his unique way of seeing the ninja world. Maybe Orochimaru starts to secretly guide Naruto in some unorthodox ways of chakra control, which Naruto initially resists but later realizes could be useful.
One plot idea could be Orochimaru finding a way to truly achieve immortality that doesn't involve body - hopping. Maybe he discovers an ancient jutsu that links his soul to the very essence of the ninja world. Another idea is Orochimaru teaming up with Naruto to face a new, greater threat, and in the process, Naruto starts to understand Orochimaru's pursuit of immortality from a different perspective. And perhaps Orochimaru could create a new form of immortality that is more about passing on his knowledge and skills in a unique way rather than just living forever physically.
Perhaps Orochimaru's experiment accidentally releases an ancient evil that was sealed long ago. Naruto, being the hero he is, takes it upon himself to reseal the evil. Along the way, he discovers secrets about his own family and the origin of chakra that are linked to Orochimaru's experiment.
One plot idea could be that in a world where Sakura is male, he and Naruto are on a mission together and get trapped in a cave. During their time there, they start to open up about their insecurities and feelings for each other, leading to a deeper bond. Another could be that male Sakura is a medic nin who has to take care of an injured Naruto after a battle. As he nurses Naruto back to health, they realize their feelings have changed. A third idea is that they are both entered in a ninja tournament and as they compete against others and support each other, a romantic relationship begins to form.
One plot idea could be a journey of self - discovery for Naruto within the context of his relationship with Madara. Maybe Naruto starts to question his own feelings and how they've changed towards Madara over time. Another could be a scenario where they are forced to team up against a common enemy and during this time, their relationship deepens in a yaoi - themed way.
One interesting story could be about Naruto's journey of understanding Orochimaru's complex past. In this fanfiction, Naruto might start to see Orochimaru not just as a villain but as a troubled soul. It could show how their interactions change over time as Naruto tries to bring out the good in Orochimaru. This could involve Naruto using his own experiences of being an outcast at times to relate to Orochimaru.
Maybe in the fanfiction, Naruto gets trapped in one of Orochimaru's old experiments. Female Orochimaru, out of curiosity about Naruto's power and his unique personality, decides to study him up close. But during this time, Naruto manages to show her the value of human connection and kindness, which she has long forgotten, leading to a deep bond between them.
One plot idea could be Orochimaru seeing some potential in child Naruto that is different from the Nine - Tails. Maybe he wants to train Naruto in a different form of jutsu, not for evil but for some self - serving yet not completely malicious purpose. For example, he could be interested in Naruto's ability to make friends and wants to use that to his advantage in the ninja world.
