In this fanfiction, Naruto's character development would be a complex journey. Starting off, he'd be very much like the demon foxes in terms of behavior and values. But as he gets exposed to the outside world, he'd start to change. He might see the good in humans and try to adapt. However, his roots with the demon foxes would always be there. He could develop a new form of ninjutsu that combines the power of the foxes with human - taught techniques. This would make him a very unique and powerful ninja, but also a very conflicted one as he tries to reconcile his two very different worlds.
His character would be more feral. He'd be more in tune with his instincts like the demon foxes. So he might be quicker to anger and more impulsive in his actions.
Naruto would probably have a stronger sense of loyalty to those he considers his 'pack' (the demon foxes). This could make him more distrustful of humans at first. As he grows, he might struggle to fit into human society due to his upbringing. His sense of humor might also be different, more animal - like growls or howls could be part of it. He would have to learn to balance his fox - like nature with the need to interact with humans as a ninja.
Naruto might develop a more wild and instinctual side. Since he is raised by foxes, he could be more in tune with his animal instincts. For example, he may be quicker to react based on his gut feelings rather than overthinking like a normal human would.
His character might be more hardened. Growing up with Yahiko, he'd be exposed to the harsher side of the ninja world earlier. So he'd be less likely to trust blindly.
Naruto would be more disciplined. Gai's strict training regime would make him more focused on his goals.
Naruto's character would likely be more distrustful of traditional ninja institutions. Since he's raised by a rogue, he might see the established ninja villages as corrupt or overly restrictive. He could be more rebellious and less likely to follow orders blindly.
Naruto might become more sensitive and perceptive. Since kunoichi often have a different way of looking at things compared to male ninjas, Naruto could pick up on those traits.
Naruto's view of family would be different if raised by Pakura. Since Pakura could be seen as a surrogate mother figure, he'd have a different understanding of maternal love. This would affect his relationships with others, especially female characters. He might be more respectful towards women from the start. His growth as a ninja would be more centered around Suna's way of life. For example, he'd be more involved in protecting Suna's trade routes and resources, which would shape his ninja skills and values in a way that's distinct from his Konoha - raised self.
Naruto would probably be more in touch with nature. Since slugs are associated with earth and natural elements, he might have a calmer and more patient side to him.
Naruto's character would likely become more brooding. Sephiroth's influence could make Naruto more introspective and less likely to wear his heart on his sleeve. He might develop a colder exterior to match Sephiroth's aloofness.
His character would develop with a stronger sense of loyalty towards Jiraiya. He would inherit Jiraiya's values like protecting the weak and seeking justice. Naruto would also be more well - versed in the ninja arts and history due to Jiraiya's teachings. This would make him more respected among his peers at an earlier stage. Moreover, he might be more patient and less impulsive as Jiraiya could teach him the importance of thinking before acting.
Naruto's character would likely become more reserved in some ways. Yamato is not as boisterous as some of Naruto's other influences, so Naruto might think before he acts more often. His fighting style could also be more strategic, incorporating Yamato's wood - style and knowledge of chakra control.
