The OC in Orochimaru's body could also change the relationship between Orochimaru and his former students like Kabuto. Instead of using Kabuto as a tool, the OC might actually mentor him in a more positive way. This could lead to Kabuto having a different role in the story. He could potentially become an ally to the main characters much earlier, and his power could be used for good rather than being a pawn in Orochimaru's and later Tobi's plans.
The OC as Orochimaru could have a major impact on the Akatsuki. Maybe they would try to infiltrate the group and undermine their plans from the inside. Since Orochimaru was once part of the Akatsuki, the OC could use this position to gather information and prevent the Akatsuki from capturing the tailed beasts. This would change the entire course of the story as the Akatsuki's actions were a major driving force in the Naruto plot.
If an OC was reborn as Orochimaru, they might not attack Konoha in the same way. They could try to form an alliance instead, seeing the potential in working with the village rather than against it. This would change the whole dynamic of the early Naruto story, especially Sasuke's journey as he might not be so hell - bent on revenge against Konoha if Orochimaru wasn't an enemy.
The story would also change in terms of Naruto's relationships. His friends like Sasuke and Sakura would be very concerned and might try to stop him. This could lead to a rift between them. Naruto might gain new powers faster, but at a cost. He could start to lose his connection to his normal self and the Nine - Tails inside him might react negatively to the experiment.
Well, it could make Naruto a much darker character. Instead of his usual optimistic self, he might be filled with vengeance. This would change the dynamics of his relationships. His friends would have to deal with this new, brooding Naruto. Also, it might slow down his progress in becoming a stronger ninja as he has to first deal with the trauma of the torture.
Naruto could develop a new sense of determination. He might be determined to not let Orochimaru's experiments define him. Instead, he could use what has happened as a motivation to become stronger in his own way. He may also start to study more about the type of experiments Orochimaru was doing, not to replicate them, but to find ways to counter any future threats related to that kind of science.
Yes. A Naruto OC who is a good Orochimaru can bring a fresh perspective. It might explore Orochimaru's character in a new light, showing his potential for good that was not fully explored in the original series. The OC could interact with Orochimaru in ways that make the story engaging and different from the typical Naruto plotlines.
One idea could be that the OC, with all their modern - world knowledge, uses it to enhance Orochimaru's experiments in a different way. For example, they might introduce new concepts of genetics that hadn't been explored in the Naruto universe yet. This could lead to new types of jutsu or even a different approach to immortality.
Maybe the fanfic could start with the OC being experimented on by Orochimaru. Naruto and Itachi somehow cross paths with the OC. Itachi, seeing the OC's situation, decides to help, which leads to a complex relationship between them all as Naruto tries to understand Itachi's motives and the OC tries to break free from Orochimaru's control.
One potential plot could be the OC trying to learn Orochimaru's jutsu for good purposes. Maybe they want to use his knowledge of forbidden jutsu to heal people or protect the village in a way that was not thought of before.
It changes the Naruto universe in several ways. Firstly, Fem Orochimaru's actions would be different from the male Orochimaru's. Her motives for taking Naruto might not be as purely power - hungry. This could lead to different alliances and enmities. For example, some characters who were against Orochimaru might be more lenient towards Fem Orochimaru if she shows a more benevolent side. Secondly, Naruto's growth and development would be altered. Instead of following the path with Jiraiya, he's with Fem Orochimaru. So his jutsu and combat style might incorporate more of her unorthodox and perhaps more feminine - influenced techniques. Also, the perception of Orochimaru's lair or hideouts would change. It could be less of a spooky, evil - filled place and more of a place of mystery and potential redemption.
Naruto would likely be more cunning. Since Orochimaru is known for his devious ways, Naruto might inherit some of that. He could be more calculating in battles rather than just relying on brute force. However, he would still have his core of kindness. So, it would be an interesting mix of Orochimaru's slyness and Naruto's big - heartedness.
Naruto would likely become more secretive. Since Orochimaru is a very private and often devious character, Naruto might pick up some of those traits. He would probably keep things from his friends more often.
