His sense of strategy would improve. Zabuza is a tactical fighter, and Naruto would learn to plan better in battles.
If trained by Zabuza, Naruto would probably grow in terms of his combat intelligence. He'd learn to read his opponents better. His personality could become more stoic, as Zabuza is not one for excessive emotions. But Naruto would also bring some of his own warmth to Zabuza's cold - blooded training regime. He might try to humanize Zabuza and in the process, become a more complex character with a blend of Zabuza's ruthlessness and his own compassion.
Naruto's character development would be multi - faceted. He would become more strategic in his approach to combat. Yamamoto's battle experience and knowledge would be passed on to Naruto, making him a more well - rounded fighter. Emotionally, he might become more reserved in some ways. Since Yamamoto is not as outwardly emotional as Naruto, Naruto would learn to control his emotions better during battle. However, he would still retain his core values of protecting his friends and the village. This new training would just enhance his ability to do so more effectively.
His understanding of the ninja world would expand. He might become more cautious and calculating in battles, as Kaguya's training could expose him to different strategies. Also, he could develop a more solemn side to his personality, considering Kaguya's own complex nature and the heavy knowledge she might share.
His understanding of the ninja world might deepen. Yugao has different experiences compared to his other mentors. So, Naruto could learn about different aspects of the ninja life, like the sacrifices ANBU members make. This would make him more mature in his thinking.
Naruto would become more confident. With Kurama's training, he'd know he has more power and skills at his disposal, so he'd face challenges with less hesitation.
Naruto would likely become more patient. Kurenai's training methods might force him to slow down and think more carefully, which is different from his usual impulsive self. This could lead to him making better decisions in battles.
His understanding of the Uchiha and the darker side of the ninja world would deepen. Itachi would share his experiences, and Naruto would gain a more nuanced view. This might make him more empathetic towards enemies. Also, his combat skills would diversify. He could incorporate Itachi - like precision and speed into his fighting style, becoming a more well - rounded ninja.
Naruto would probably become more disciplined. His impulsive nature might be tempered by Mifune's strict training regime.
If Naruto were trained by Enma in a fanfiction, his character would develop in several ways. Firstly, he'd gain more self - control over his powers. Enma could teach him how to better manage the Nine - Tails' chakra, making him less likely to lose control. Secondly, Naruto would become more in tune with nature. Enma, being a part of the toad world, could show Naruto how to draw strength from nature, just like in Sage Mode. This would not only enhance his power but also give him a deeper understanding of the world around him. Moreover, Naruto would become more respected among the toads, which could boost his confidence and leadership skills.
Naruto's character might become more solemn. Hiruzen's influence could make him less of a prankster. He'd be more focused on his training and responsibilities as a ninja.
