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.
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.
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.
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.
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, it could be that DIO imparts his unorthodox and powerful combat skills to Naruto. Maybe Naruto learns DIO's time - stopping ability in some unique way, which gives him an edge in battles against tough opponents in the Naruto universe. And he might also pick up DIO's menacing charisma, making him a more intimidating presence on the battlefield.
In a 'Naruto trained by ANBU' fanfic, the plot could involve Naruto being secretly taken under the wing of ANBU members. They might train him in stealth and more lethal forms of combat. This could lead to Naruto having a different fighting style compared to canon, and he might face different challenges as he grows stronger. For example, he could be involved in more covert missions early on and develop a reputation among the ANBU ranks.
Well, it could start with Naruto being sent on a special mission where he encounters Sasori. Sasori, seeing potential in Naruto, decides to train him. The training would likely be tough as Sasori is a strict teacher. Naruto would have to adapt to Sasori's methods. He might learn how to control multiple puppets at once, and this new skill could help him in battles against stronger opponents in the future. For example, when facing Akatsuki members or other powerful foes.
In a fanfic where Naruto is trained by Zetsu, the story could take an interesting turn. Zetsu has knowledge of the Akatsuki and their secrets. Naruto could learn about the organization from the inside out. This knowledge could help him in his quest to bring peace. He might also gain some physical enhancements. Zetsu is quite durable in his own way, and Naruto could inherit some of that sturdiness. This would make him an even more formidable opponent in battles against strong foes like Pain or Madara.
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.
