How would Naruto's character change if he is trained by Orochimaru in fanfiction?

Naruto would become more cunning. Orochimaru is a very sly character, and his training would likely rub off on Naruto. Naruto would no longer be as straightforward in his battles and interactions. He might start to think several steps ahead, like Orochimaru does.

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.

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.

Naruto's character would change a great deal. He would be exposed to Orochimaru's world of experimentation and dark magic. This might make him more cynical about the ninja world. Also, he would have to adapt to Orochimaru's strict and often cruel training methods. As a result, he could become more introverted and less trusting of others. His once open - hearted nature might be replaced with a more guarded one.

Naruto would probably become more serious. Shisui was a serious - minded ninja. His training might make Naruto less impulsive and more calculated in his actions.

He'd be more cynical. Orochimaru's ways would make Naruto question the goodness in people.

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.

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'd probably become more adaptable. Naruto is already flexible in combat, but RWBY's diverse combat styles would force him to be even more so. His personality might also become more open - minded as he experiences the different cultures and ways of thinking in the RWBY world.

If Naruto is trained by Deathstroke in fanfiction, his character would change in multiple ways. For one, he might lose some of his naivete. Deathstroke's world is a harsh one, and Naruto would have to adapt. He could become more calculating and less likely to jump into a fight without thinking. His relationships with his friends might also change. He might start to keep them at a bit of a distance, not wanting to put them in danger as a result of his new, more dangerous fighting style.
