His relationships with others would also change. For instance, his bond with Sasuke might not be as intense in terms of power rivalry. Since he doesn't have the Kyuubi, Sasuke may not see him as a threat in the same way. Naruto would probably have to work harder to prove himself worthy to his friends and the village. He'd be more of an underdog in a different sense, relying solely on his own efforts and natural talents rather than the Kyuubi's power, which would lead to a more humble and determined Naruto.
If Naruto is the son of Kyuubi in the fanfiction, his character development would be drastically different. He would have a different kind of self - discovery journey. His relationship with the villagers could be more hostile from the start. They might not just see him as the container of the Kyuubi but as the actual offspring of the beast they fear. This would force him to grow up faster, in a sense. He would have to prove himself not just as a ninja but as someone worthy of acceptance despite his 'parentage'. His training might also focus more on controlling his in - born Kyuubi - like traits rather than just taming the Kyuubi's power within him.
Naruto's character development would be drastically different. He might be more in tune with his 'fox - like' nature from the start. Instead of fearing the Kyuubi's power, he could embrace it as part of his identity.
Naruto might develop different skills. Without Jiraiya's training, he could focus more on self - taught techniques or learn from other characters. For example, he might learn more about the Uzumaki clan's unique abilities from someone else in the village.
Naruto might become more conflicted. Since Madara had some extreme views, Naruto would have to grapple with those ideas. He could become more secretive as he tries to understand Madara's motives better without alarming his friends. For instance, he might start training alone more often to study Madara - inspired techniques.
Naruto being raised by Sasori would be a huge shift. Sasori is not one to show much emotion or promote the ideals of hope and perseverance like the people in Konoha. Naruto would likely have a different sense of loyalty, perhaps more towards Sasori's goals or ideals which are mainly centered around his own power and the art of puppetry. His growth as a ninja would be more focused on silent and deadly skills rather than being a hero that everyone looks up to. His relationships would be more transactional in nature as he wouldn't have been exposed to the deep emotional bonds that are so prevalent in Konoha.
If Naruto was raised by Vegeta, his character would likely become much more aggressive and focused on power. Vegeta's Saiyan pride and his constant drive to be the strongest would rub off on Naruto. He might not be as friendly or as empathetic as in the original series, but would instead be more solitary in his pursuit of strength, seeing it as the ultimate goal.
It would likely accelerate his growth. Jiraiya is a very experienced ninja. With his guidance, Naruto would gain more confidence. For example, if Jiraiya found Naruto early on, he could teach Naruto better control of his chakra, which was a struggle for Naruto in the beginning. This would make Naruto more efficient in battles and less reliant on brute force.
Naruto would likely become more disciplined. Kakashi is known for his strictness, so Naruto would have to follow a more structured training regime. This would make him more focused during battles and in his studies of ninjutsu.
Naruto would become more well - rounded. With Hiruzen's training, he'd gain more discipline. In the original, Naruto was a bit of a wild card. But under Hiruzen, he'd learn to control his impulses better. For example, in battles, he'd think more strategically instead of just charging in.
Kyuubi's comfort can make Naruto more confident. Knowing that he has Kyuubi's support, he may take on more difficult missions without hesitation. For instance, if he's facing a powerful enemy, he'll remember Kyuubi's words of encouragement and stand his ground firmly.
