Naruto's personality would be drastically different. He would not have the same sense of optimism that he has in the original story. Instead, he would be more in tune with the Akatsuki's somber view of the world. He would be more distrustful of the so - called 'good' ninja villages like Konoha. His sense of justice would be warped according to the Akatsuki's ideals. He might see the tailed beasts not as friends but as tools for power, which is a complete contrast to his original self. He would also be more independent, as the Akatsuki doesn't really have the same sense of community as Konoha, so he'd have to fend for himself more often.
If Naruto was raised by Akatsuki, his personality would change a great deal. He would likely be more secretive. Growing up in the Akatsuki environment, he'd be used to keeping things under wraps. Also, he might be more ruthless in achieving his goals. The Akatsuki's cut - throat nature could rub off on him, making him less hesitant to use force when necessary.
Naruto's personality could be a lot more family - oriented. Mikoto is all about family, so Naruto would likely pick up on that. He'd be more in tune with the importance of family bonds. Also, he might be less of an outcast as he'd have the support of the Uchiha family, which could make him more confident and less of a prankster.
His personality would likely be a mix of Zabuza's stoicism and his own inherent determination. He might not show his emotions as freely, but deep down still have that strong will to prove himself. He could also be more distrustful of others at first, having grown up with Zabuza who is a bit of a loner. However, as he gets older, he might start to break out of that shell and show more of his true, kind self.
He'd probably be more cautious. Quarians live in a fragile environment, and Naruto would grow up learning to be careful. So, instead of his usual head - on approach, he might think more before acting.
Naruto's personality would likely become more stoic. Zoro is often calm and collected in the face of danger. Growing up with Zoro, Naruto would learn to control his emotions better. He might not be as quick to jump into things without thinking, as he would have been influenced by Zoro's more measured approach. Also, he might be more confident in a quieter way, not relying as much on shouting about his goals but rather showing through his actions like Zoro does.
He'd probably be more carefree. The toads have a different lifestyle compared to humans in Konoha. So Naruto might not be as eager to prove himself to the villagers right away. He'd be more in tune with nature like the toads.
Naruto's personality could be a blend of his original upbeat and determined self with Gaster's more enigmatic and calculating nature. He might be more secretive about his plans and abilities. For example, instead of shouting about his goals all the time like in the original Naruto, he would keep them to himself and work quietly towards them. He could also be more curious about the unknown and scientific aspects of things, which is something he would pick up from Gaster.
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.
If raised by Kushina, Naruto would have a more nurturing personality. Since Kushina is a loving mother figure, Naruto would grow up seeing and learning from her kindness. He'd be less likely to seek attention through pranks as he'd already have the love and attention he needed at home. His self - esteem would be higher, and he might be more diplomatic in his interactions with others, having learned from Kushina's way of handling things.
He'd probably be more solemn. The Shinigami is a being associated with death, so Naruto would be exposed to serious concepts early on.
His personality would likely be more disciplined. The Hokage's influence would instill a sense of order in Naruto. He'd be less likely to pull pranks just for attention.
