He'd probably be more aggressive. The xenomorphs are aggressive creatures, so Naruto might not be as friendly as in the original story.
His personality could be a mix of his original self and the xenomorph - like traits. He might be more solitary, as xenomorphs are not very social in the way Naruto's friends are. But he could also still have some of his old Naruto charm, just a bit more subdued.
He'd be more disciplined. Samurai culture emphasizes self - control, so Naruto would be less impulsive.
Naruto could be more empathetic towards the Uchiha's cause. Since Mikoto is his mother figure, he would be exposed to the Uchiha's history and their grievances from a young age. This would make him more understanding of Sasuke's later actions and more likely to try and find a peaceful solution for the Uchiha's problems.
He might be more aloof. Since a phoenix is a rather otherworldly creature, Naruto could pick up some of its more detached qualities. He may not be as quick to make friends as in the original story, instead observing more from a distance before approaching others.
His personality might be more serious. Since Onoki is a no - nonsense leader, Naruto could pick up that trait. He might be less impulsive and more calculating in battles.
Naruto might be more distrustful. Since Kabuto has been involved in many underhanded schemes, Naruto could grow up thinking that everyone has ulterior motives. This would be a big change from the original Naruto who was so quick to trust and befriend others. He would also probably be more self - reliant as Kabuto may not encourage the same kind of teamwork that Naruto was exposed to in Konoha. He would be more likely to rely on his own skills and knowledge, which could make him a more solitary figure in the ninja world.
Naruto might be more distrustful of the Hidden Leaf Village. Since he's being raised by a missing - nin, he would hear different perspectives that might make him question the village's motives and actions.
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.
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.
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.
