If Orochimaru was Naruto's sensei in fanfic, Naruto's view of the ninja world would probably change drastically. He would be exposed to Orochimaru's view of power and immortality. This could lead to Naruto either trying to reform Orochimaru's ideas or struggling with his own values as he is constantly in the presence of such a morally ambiguous figure. Also, Naruto's relationships with his friends might be affected as they would be suspicious of his association with Orochimaru.
Naruto might learn some very dark and powerful jutsus. Orochimaru is known for his forbidden jutsu knowledge. So Naruto could become a much more dangerous fighter but also risk being influenced by Orochimaru's immoral ways.
In some fanfics, Orochimaru can be made Naruto's sensei. Fanfic authors often like to play with the original story's elements and create unique scenarios. They might think that having Orochimaru as Naruto's sensei would lead to a very different kind of character development for Naruto, full of more moral and ethical challenges due to Orochimaru's dark nature.
Perhaps Naruto goes to Orochimaru in an attempt to redeem him. Naruto has a strong belief in the good in people, and he might think that he can convince Orochimaru to stop his evil ways. He could offer Orochimaru a chance at redemption, like a new start in the Hidden Leaf Village if he gives up his dark experiments and ambitions. This would lead to a complex relationship development between them, with Orochimaru being skeptical at first but gradually considering Naruto's offer.
If Ibiki were Naruto's sensei in a fanfic, Naruto would likely gain a whole new set of skills. Ibiki is known for his interrogation and torture techniques, so Naruto could potentially learn about getting information from enemies in a more effective way. Also, Ibiki's strict and disciplined nature would probably make Naruto more responsible and less impulsive. This could change the way Naruto approaches battles and missions, as he would be thinking more strategically instead of just relying on his brute strength and the Nine - Tails' power.
In this kind of fanfic, Naruto might be in a really tough situation. Orochimaru could be after his chakra or some secret power within him. Maybe Naruto will try to use his shadow clones to escape or call for help using his toad summons.
Well, for one thing, the whole dynamic of the story would change. Naruto's relationship with the village would be much more complex. Since Orochimaru is seen as an enemy by the village for a long time, Naruto might face more discrimination or suspicion. Also, his training and the way he develops his skills would be different. He could inherit some of Orochimaru's forbidden jutsu much earlier and have a different approach to combat and power - seeking. And the story would have to re - imagine Naruto's relationships with other characters like Sasuke and Sakura, as his family connection to Orochimaru would color all those interactions.
One thing that could happen is that Naruto would learn a lot more about the toad sage mode earlier. Jiraiya could start training him right away. This would give Naruto an edge in battles. He would be able to use the toad - related jutsu more effectively and have a different combat style.
Well, Naruto might learn some unique jutsu from Anko. Since Anko is known for her snake - related techniques, Naruto could incorporate some of those elements into his own fighting style. Maybe he'd become even more unpredictable in battles.
Well, Naruto could potentially be used as a bargaining chip by Orochimaru. Orochimaru might try to trade Naruto for something he wants from Konoha, like secret jutsu scrolls or some kind of political power within the village. And Naruto, being the determined hero he is, would likely be constantly looking for a way to escape and foil Orochimaru's plans.
In some fanfictions, Naruto might go to Orochimaru seeking power. He could be tempted by Orochimaru's knowledge of jutsu. Maybe he thinks that by learning from Orochimaru, he can become stronger faster and be better able to protect his friends and the village.
In a fanfic where Naruto is one of Orochimaru's experiments, it could completely change the trajectory of his life. First, his training under Jiraiya might be affected. Jiraiya might be more cautious or even hesitant to train him further. Naruto's own view of himself would also change. He might question his identity and purpose more deeply. His powers could be a mix of his original abilities and the modifications made by Orochimaru. This could lead to some really interesting battles where Naruto has to learn to control these new powers while still holding onto his values. And his interactions with the other characters, like Sasuke and Sakura, would be very different. Sasuke might see him as a more direct threat, and Sakura might be more worried about his well - being.
