Naruto would probably develop a greater sense of responsibility earlier. Since the Nara clan has its own set of values and traditions, he'd be taught to uphold them. This could lead to him being more reliable and less of a prankster. He'd also be more in tune with nature and the environment around him, as the Nara have a connection to nature through their jutsu.
Naruto's character would become more strategic. Since the Nara clan is known for their intelligence and strategic thinking, he'd pick up on those traits. He might be less impulsive in battles and more likely to plan ahead.
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.
He might become more stoic. Given the nature of Shinigamis, Naruto could grow up with a sense of calmness and detachment that's not typical in the original Naruto.
His character would likely become more independent. Growing up with Igneel, he'd have to rely on himself more. He might be less impulsive as he learns from Igneel's wisdom. For example, instead of rushing into battles without a plan, he'd think more strategically.
Naruto would likely be more confident. With the bijuu by his side from the start, he wouldn't have to face the same level of loneliness and self - doubt. His character might be more assertive and less impulsive as he'd have the wisdom of the bijuu to guide him.
His character would likely become more secretive. Naruto is known for his openness, but under Medusa's influence, he might hold his cards closer to his chest. He'd also be more attuned to danger and survival, as Medusa would have instilled in him a sense of self - preservation that the original Naruto lacked in his early days.
Naruto would probably be more independent in his thinking. Instead of relying on the typical ninja values taught in the village, he'd draw from the Shinigami's teachings. This could make him a bit of a rebel in the eyes of the ninja community. He might question the established norms more often. His development would also be influenced by any special tasks or missions the Shinigami gives him. For instance, if he has to deal with restless souls, it would make him more empathetic towards those in pain, but also more determined to maintain the order between the living and the dead.
He'd likely be more independent. Summons are often self - reliant, and growing up with them would instill that trait in Naruto. He might not rely as much on others for help.
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 development would be quite different. Since Hana is from a different background than the people who initially influenced Naruto in the canon. He might be more reserved in some ways. Hana's no - nonsense attitude could rub off on him, so he'd be more practical in his approach to problems. Also, his relationship with his peers might be more of an equal footing from the start, as he wouldn't have the same 'outsider' complex, which would change how he interacts and forms bonds with others.
