Naruto would be less naive. Orochimaru's influence would force him to grow up fast and be more calculating. He'd probably be more secretive too, as Orochimaru is all about hidden motives. Naruto might also be more ruthless in achieving his goals, having learned from Orochimaru that sometimes you have to do whatever it takes.
He'd be more cynical. Orochimaru's ways would make Naruto question the goodness in people.
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'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.
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 was raised by Orochimaru in fanfiction, his relationships would be turned upside down. His friendships from the Leaf Village would be in jeopardy. Since Orochimaru is not one to value the kind of loyalty and friendship that Naruto's friends in the Leaf do, Naruto would have a hard time understanding and maintaining those relationships. He might even be hostile towards them, seeing them as obstacles in his pursuit of power. His relationship with the Hokage would also be a mess. Instead of looking up to the Hokage as a role model, he would probably view the position as something to be conquered or undermined, following Orochimaru's ideology of power - seeking.
Naruto's character development in this fanfiction would be complex. He'd probably grow up with a sense of superiority due to Orochimaru's powerful teachings. But at the same time, he'd lack the warmth and compassion that came from his relationships in Konoha. He might be more self - centered, focused on his own power and survival. He may not have the same sense of justice as in the original Naruto, as Orochimaru's motives are not in line with the general good. And his relationship with his peers would be more of a power struggle. He might not form the same deep friendships, but rather see others as either tools or threats.
He would become more cynical. Orochimaru's influence would make Naruto question the values he once held dear in the village. His appearance might also change, with a darker look in his eyes and a more menacing aura.
He would be highly skilled in combat from a young age. The ANBU Commander would train him rigorously, so Naruto could be a prodigy in various ninja arts. His fighting style might be more calculated and less reliant on brute force and the Nine - Tails' power. He would have a better understanding of strategy and tactics.
Well, Naruto's character might become more morally ambiguous at first. Since Orochimaru is a rather shady character, Naruto could start to question some of his previous beliefs. He might become more power - hungry, but also more self - reliant in a way as he tries to master the new power. However, he could also struggle with the darker aspects of Orochimaru's power, like having to use some underhanded tactics.
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.
Naruto would likely become more secretive. Since Orochimaru's training methods are often not in line with Konoha's values, Naruto would have to hide what he's learning. He might also become more distrustful of others as Orochimaru could instill in him the idea that everyone is out to get him for his newfound power.
