A 'naruto trained by orochimaru fanfic' might have Naruto delving deeper into the secrets of the Sharingan. Orochimaru has always been interested in the Uchiha's power. So Naruto, under his training, could be exposed to knowledge about the Sharingan and its potential. This might lead to some interesting power - ups for Naruto, but also put him in the crosshairs of other powerful ninja who are also interested in the Sharingan's secrets.
Well, one possibility is that Naruto could gain a much darker and more ruthless fighting style. Orochimaru might teach him some forbidden jutsu that are not part of the regular Konoha training. Naruto could also struggle with the moral implications of being trained by such a villain. For example, he might question whether using Orochimaru's methods to protect the village is the right thing to do.
In fanfiction, if Naruto were trained by Orochimaru, he might gain some very dark and powerful jutsu. Orochimaru is known for his unethical experiments and forbidden jutsu. Naruto could become a more morally ambiguous character, as Orochimaru's influence might taint his usually positive and straightforward nature. His power level would likely skyrocket, but at the cost of his relationships with his friends in Konoha who might be wary of his new, darker abilities.
Naruto's morality could be somewhat skewed. Orochimaru has a very different view on right and wrong compared to Naruto. So, Naruto might start to question some of his previous beliefs. For example, he might be more willing to use dangerous or forbidden jutsus if it means achieving his goals. He'd also probably be more distrustful of others, as Orochimaru always has ulterior motives. This would be a big change from the Naruto who was always so quick to trust and befriend people.
If Naruto were trained by Orochimaru in fanfiction, it could lead to all sorts of plot twists. He might struggle with the temptation of forbidden jutsus and have conflicts with his former allies. Also, his relationships with other characters could undergo major shifts.
Well, the plot could involve Naruto being trained in Orochimaru's lair. He'd be exposed to Orochimaru's experiments and might gain some unique powers from them. For example, he could have better control over snakes or learn some snake - based jutsu. His view of the ninja world might also be warped as he grows up in Orochimaru's influence, seeing things more from a survival - of - the - fittest perspective.
Well, it could be that Itachi trains Naruto to better control his chakra. Maybe Itachi sees potential in Naruto to bring peace to the ninja world and decides to pass on his unique skills like the Sharingan's insights on combat.
In a 'naruto trained by ruby' fanfic, perhaps Ruby could introduce Naruto to some unique combat styles. Maybe Ruby has her own set of skills like some kind of magic or special weapon techniques. She could teach Naruto how to combine his chakra with these new elements. For example, if Ruby has some sort of elemental magic, Naruto could learn to infuse his Rasengan with that magic for a more powerful attack.
In a 'naruto trained by selphe fanfic', perhaps Selphe comes from a different ninja clan with ancient techniques. She could teach Naruto how to combine his existing Rasengan technique with her clan's special chakra manipulation. This would make Naruto's attacks even more powerful and unpredictable. Also, Selphe might train Naruto in mental discipline, which would help him better handle the stress of battles and his role as a future Hokage.
Well, it could be about Naruto learning unique combat techniques directly from the Kyuubi. The Kyuubi, being a powerful and ancient entity, might teach Naruto some forgotten or forbidden jutsu. This would set Naruto apart from his original training path in the canon series. Maybe he'd learn how to use the Kyuubi's chakra in a more controlled and strategic way, like creating chakra shields or new types of elemental attacks.
Well, it could be that Naruto gets super powerful training from each of the Sannin. Jiraiya might teach him more advanced toad jutsus and how to better control his chakra. Tsunade could train him in medical ninjutsu and physical combat skills. Orochimaru, even though he's a bit of a dark character, could show Naruto some really unique and forbidden jutsus that Naruto has to learn to resist the dark side of. And all this special training could make Naruto a much more formidable shinobi in the fanfic.
