If raised by Tsunade, Naruto could be more empathetic. Tsunade has experienced great loss, and she might teach Naruto to understand others' pain more deeply. His sense of humor might also change. Instead of his goofy and sometimes childish humor, he could develop a more dry, sarcastic sense of humor like Tsunade. His overall personality would be a blend of his original self and the qualities he would pick up from Tsunade, making him a more complex and interesting character.
His personality might be more reserved. Tsunade is not as boisterous as some of Naruto's other mentors. So he could be less likely to jump into things without thinking. For instance, he might analyze a situation more carefully before acting.
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 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.
He'd be more disciplined. Samurai culture emphasizes self - control, so Naruto would be less impulsive.
He'd probably be more aggressive. The xenomorphs are aggressive creatures, so Naruto might not be as friendly as in the original story.
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.
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 more reserved at first. Tsunade is a no - nonsense type, and Naruto would have to learn to be more composed. He might be less impulsive in his actions.
One possible scenario in this fanfiction could be that Naruto grows up with a more balanced upbringing. Tsunade might teach him medical ninjutsu and how to control his emotions better. Jiraiya, on the other hand, would surely train him in powerful combat techniques and in the ways of the sage. Naruto would probably be more mature and well - rounded at an earlier age, with a combination of Tsunade's tough love and Jiraiya's adventurous spirit guiding him.
