Naruto's character development could be significantly altered. If Orochimaru saves him, Naruto may start to question his own beliefs about redemption. He has always believed in giving second chances, but being saved by Orochimaru could test the limits of that belief. He might struggle with whether Orochimaru can truly be redeemed or if he is just using Naruto. This internal struggle could make Naruto more introspective and less impulsive. He may also become more cautious in his relationships, not wanting to be used again. And his view of power might change too. He could see that power can be used in different ways, not just for good like he always thought, which would add more depth to his character.
In such a fanfiction, Naruto's character development would be completely different. He would probably grow up with a sense of isolation. Since Orochimaru was an outcast, Naruto might face similar situations. This could make him more cynical about the world around him. However, Naruto's inherent goodness might also make him try to break away from Orochimaru's shadow. He might strive to prove that he is not like his brother, which could lead to a very different kind of hero's journey compared to the original Naruto story.
Well, initially, the curse mark might make Naruto more aggressive. He has to constantly fight the dark influence it brings. This could lead to him being more isolated as he fears hurting his friends. But in the long run, it also gives him a new source of power to master, which in turn makes him more determined and self - aware in his growth.
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.
Well, it could enhance his jutsu arsenal significantly. Orochimaru has a vast knowledge of various jutsus. Naruto might gain access to Orochimaru's snake - based jutsus like the Hidden Shadow Snake Hands. Also, Orochimaru is very proficient in forbidden jutsus. Naruto could potentially have a better understanding of these dangerous techniques, but he would also have to deal with the darker aspects of Orochimaru's power and the possible corruption it might bring to his own chakra nature.
Naruto could develop a new sense of determination. He might be determined to not let Orochimaru's experiments define him. Instead, he could use what has happened as a motivation to become stronger in his own way. He may also start to study more about the type of experiments Orochimaru was doing, not to replicate them, but to find ways to counter any future threats related to that kind of science.
Naruto could also become more vengeful. If he survived the experiments, he would likely be angry at Danzo for what he had done. This could lead to a darker side of Naruto emerging, where he is focused on getting revenge rather than his original goal of becoming Hokage and being accepted by the village. He might be more willing to use force and be less forgiving.
It makes Naruto seem more mysterious. Since Orochimaru is a rather enigmatic and often villainous character, Naruto looking like him in the fanfiction gives him an air of mystery that he doesn't typically have in the original series. People reading the fanfiction might start to question Naruto's true nature.
Well, if Naruto was Tsunade's son in the fanfiction, his character might become more confident earlier. Tsunade is a strong and respected figure in the Naruto world. Having her as a mother could mean Naruto has more direct access to powerful jutsu training and political influence. He might not be as much of an underdog as in the original story, which could make his journey to becoming Hokage a bit different. He could also inherit some of Tsunade's gambling habits, which would add an interesting twist to his character.
It makes him more complex. Instead of just having his Uzumaki heritage, he now has to deal with the traits and expectations of the Senju and Uchiha. He might become more introspective as he tries to understand the differences and similarities between the three lineages.
Well, being the jinchuriki of Saiken would likely make Naruto more in tune with water - based chakra. He might become more adaptable and fluid in his fighting style. His character could also grow to be more empathetic towards other jinchurikis and their struggles, as he now shares a similar burden. This new status might also lead to new friendships or alliances with those who have an affinity for Saiken's power.
