In such a fanfiction, Naruto might grow up with a strong connection to the Uzumaki heritage. Mito could teach him about their clan's sealing techniques from a young age. He'd likely have a more in - depth knowledge of the Uzumaki history and powers. This could also change his relationship with the Nine - Tails. Instead of being feared, he might be seen as a potential asset due to his Uzumaki blood and Mito's teachings.
He might be more confident. The Uzumaki clan had a strong reputation, and growing up with that knowledge could give Naruto a sense of pride and assurance from the start. He wouldn't have to struggle as much with feelings of being an outcast like in the original story.
One possible storyline could be that Naruto grows up with a strong sense of Uzumaki clan traditions. Since the Uzumaki were known for their sealing techniques, Naruto might be trained in that from a young age. He could use these skills in unique ways during his adventures, like creating more powerful seals than in the original story.
His relationship with Sasuke would be different. Without the shared experience of being outcasts in the village, they might not have the same initial bond. Naruto would have a stronger support system from his Uzumaki family, so he might not be as desperate for Sasuke's friendship in the same way.
His life would be filled with a strong sense of family and heritage. The Uzumaki are known for their strong chakra and sealing techniques. Naruto would probably learn these skills earlier. He might also have a more stable upbringing, surrounded by people who understand his connection to the Nine - Tails better.
His relationship with Sasuke would be different. Instead of the rivalry born out of their time in Konoha, it could be more of a friendly competition between two powerful clans. Naruto, being Uzumaki - raised, would have a different perspective on power and friendship.
He would probably be more in touch with his Uzumaki heritage from the start. He might learn Uzumaki sealing techniques much earlier and be a more formidable ninja at a younger age. The Uzumaki are known for their strong life force and sealing skills, so Naruto could have a different set of abilities compared to being raised in Konoha alone.
The plot would be completely different. For starters, there might not be the whole 'Nine - Tails as a lonely burden' aspect as Kushina could have helped Naruto understand and control it better. The Akatsuki's plans regarding the Nine - Tails would also be thwarted more easily. Also, Naruto might not have the same drive to become Hokage in the same way. Since he had a loving mother, his goals could be more about protecting his family and the Uzumaki legacy rather than seeking validation through the Hokage title.
His personality might be more confident. Mito was a strong - willed woman, and growing up under her care, Naruto would likely absorb some of that confidence. He'd probably be less of a prankster as he'd be more focused on learning the Uzumaki ways.
If Naruto was raised by Kushina Uzumaki, his character would likely be more confident from the start. Kushina was a strong - willed and loving person. She could have passed on her fiery spirit to Naruto. He might not have the same insecurities about being alone as he did in the original story. For example, he'd have a mother figure to encourage him and teach him about his Uzumaki heritage, which could make him more self - assured in his abilities.
