Naruto's character development in this fanfiction would be a complex blend. Izuna's influence would make him more attuned to the Uchiha way of life. He would value loyalty and family in the Uchiha sense. His sense of justice might be a bit different, perhaps more focused on the well - being of the Uchiha first. However, his Uzumaki roots would also play a role. He would still have that big - heartedness, but it would be expressed in a different way. He might be more diplomatic in dealing with conflicts, using his knowledge of both Uzumaki and Uchiha to find solutions. His growth would also be marked by a deep understanding of the Sharingan and its powers, which would give him an edge in both combat and understanding the hearts of others.
Naruto's character would likely become more serious and calculating. Izuna was a strategic thinker, and Naruto would pick up on that. He might be less impulsive than in the original story.
His character would develop with a strong sense of Uchiha pride. Since Izuna is his mentor, Naruto would be exposed to the rich history and culture of the Uchiha. He could become more reserved in his emotions, as Uchiha often are. But at the same time, his Uzumaki tenacity would still be there, just combined with Uchiha's grace. For example, he would approach battles with more finesse and less brute force.
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.
In this fanfiction, Naruto's character development would be complex. Growing up with a Jinchuuriki, he would have a deeper understanding of the power within. He might not be as loud and brash as in the original. Instead, he could be more of a silent observer at first. As he grows, he would gradually show his leadership skills in a different way. He would use his knowledge of the Jinchuuriki and their power to inspire others, and also be more diplomatic in dealing with different clans and villages, as he has seen the consequences of being an outcast through the Jinchuuriki's experience.
