In this type of fanfiction, it might also be that Naruto joins Orochimaru to spy on him. The Hidden Leaf Village realizes they need to know Orochimaru's plans from the inside. Naruto, being the brave and somewhat reckless one, volunteers for the mission. He endures Orochimaru's experiments and teachings while secretly sending information back to the village. Eventually, when the time is right, he betrays Orochimaru and uses the knowledge he gained against him.
One possible plot could be that Naruto, feeling ostracized in Konoha due to his jinchuriki status, decides to join Orochimaru. Orochimaru, seeing Naruto's potential, trains him in some dark and forbidden jutsus. Naruto might start to change, becoming more cynical. He could use his newfound powers against those in Konoha who once shunned him, leading to a series of battles between him and his former friends like Sasuke and Sakura.
In a fanfiction where Naruto joins the Akatsuki, there could be a lot of interesting character interactions. He would be in close quarters with villains like Sasori or Hidan. Naruto might try to learn more about their pasts and what led them to become members of the Akatsuki. This could also cause a rift in his relationships with his old friends in Konoha. They might see him as a traitor, while Naruto is actually trying to bring about change in the Akatsuki for the greater good.
One possible plot twist could be that Sakura initially joins Orochimaru to gain more power to protect her friends, but she soon discovers that Orochimaru has ulterior motives regarding her unique chakra abilities. For example, he might want to use her as a vessel for some dark jutsu. Another twist could be that Orochimaru's henchmen start to develop loyalty towards Sakura instead of him because of her strong will and medical skills. This could lead to a split within Orochimaru's group, with some siding with Sakura and others remaining with Orochimaru.
One plot could be that Naruto is captured by the Sound Village. Instead of being treated as an enemy, they try to convert him. They show him their training methods and how they are building a strong village. Naruto, being the curious and empathetic person he is, starts to understand their motives. He begins to think that by joining them, he can bring about change from within. So, he decides to stay and become part of the Sound Village, while still holding onto some of his Konoha values.
It could be that in this fanfiction, Naruto is on a mission with an Inuzuka member and they get into a difficult situation. Naruto shows extraordinary courage and loyalty during this mission. This impresses the Inuzuka clan so much that they start to consider him as one of their own. He then starts training with them, learning how to communicate better with the Inuzuka dogs and using their clan - specific jutsu, and he also becomes part of their family - like structure within the clan.
It could be that the bite was part of a larger plan by Orochimaru to create a new body for himself. Orochimaru is always seeking new vessels. He might think that Naruto, with his strong chakra and willpower, would be the perfect host. So, Naruto has to fight against Orochimaru's influence from within his own body, while also trying to figure out how to stop Orochimaru's overall plan.
If Naruto were to join Orochimaru in fanfiction, it would be a huge deviation from the original story. Naruto's values of loyalty and friendship would be put to the test. He might start to see the world from Orochimaru's perspective, which is often self - serving. This could also mean that Naruto would be involved in Orochimaru's plans to gain immortality, perhaps even becoming a part of his body - swapping experiments in some extreme cases.
One possible plot twist could be that Naruto is captured but instead of Orochimaru using him for his own power gain immediately, he tries to turn Naruto against Konoha. He might show Naruto some 'hidden truths' about the village that are actually lies or half - truths, creating internal conflict within Naruto. Another twist could be that Orochimaru's experiment on Naruto goes wrong in an unexpected way. Maybe Naruto's chakra reacts with Orochimaru's jutsu and creates a new form of power that neither of them can control at first.
One possible plot development could be Naruto learning some of Orochimaru's unique jutsu. For example, he might pick up on Orochimaru's snake - related techniques. This could give Naruto an edge in combat against opponents who are not familiar with such unorthodox attacks. Also, Orochimaru's knowledge of forbidden jutsu might be passed on to Naruto in a modified, less dangerous way, which could then be used to surprise his enemies in future battles.
In a fanfiction like this, the plot might involve Orochimaru having some hidden motives in becoming Naruto's 'mate'. Maybe he wants to use Naruto's connection to the Nine - Tails to gain more power for himself. But as time passes, Naruto's positive influence starts to change Orochimaru in ways he didn't expect. Naruto, on the other hand, might see Orochimaru as a project, someone he can reform, and this idea of reforming him could be the basis of their relationship in the fanfiction.
