If Naruto were trained by Madara and Hashirama, his fighting style would be a blend of their two distinct styles. Madara was known for his powerful and aggressive attacks, while Hashirama was more about using nature chakra and large - scale jutsu. Naruto would start to use his shadow clones in more complex ways, like setting up traps as Madara did. He'd also become more proficient in using natural elements in combat, perhaps creating new jutsu that combine his existing Rasengan with wood - style or other nature - based elements. His movement would be more fluid, taking cues from both Madara's agility and Hashirama's stability in battle. This new fighting style would make him an even more formidable opponent, not just in the Leaf Village but across all the shinobi world.
His relationship with Sasuke would likely be affected. Since Sasuke has a connection to the Uchiha and Naruto now has Madara's power, there could be a new dynamic. Sasuke might be both wary and intrigued by Naruto's new abilities. Naruto's relationship with the Hidden Leaf Village would also change. People would view him with a mix of awe and fear. The elders might be more cautious around him, while the younger generation would look up to him even more.
In a fanfiction where Naruto is trained by Hashirama and Madara, he would likely become an extremely powerful ninja very quickly. Hashirama's wood - style jutsu and his ability to control tailed beasts could be passed on, and Madara's combat skills and Sharingan - related techniques might also be taught. Naruto could combine his own Uzumaki chakra reserves with these new skills and become nearly unbeatable.
Naruto might also develop a more ruthless edge to his fighting. Zabuza was a cold - blooded killer in a way. While Naruto wouldn't become evil, he could be more decisive in combat, not hesitating as much when it comes to taking down opponents. He may also learn some of Zabuza's sword - fighting skills, adding a new dimension to his fighting style if he combines it with his kunai and shuriken use.
Naruto's character would develop in multiple ways. First, he would gain a deeper understanding of the ninja world's history from Hashirama and Madara. This would make him more respectful of the past and more determined to protect the future. Second, the training would be extremely tough, which would toughen his mental state. He would become more self - reliant as he learned from two of the most powerful ninjas. Also, he might develop a new sense of honor and pride in his skills, as he would be learning from the best. This could lead to a more mature and confident Naruto.
For Naruto, being trained by Madara could mean he learns how to counter Uchiha - specific techniques more effectively. His physical strength might also increase due to the intense training. Sasuke would be able to better harness his hatred and turn it into a more focused power source. Madara's teachings could expose them to ancient jutsu and knowledge that would give them an edge over their enemies. Their teamwork might also be affected, as they would both be influenced by Madara's way of thinking.
Naruto would likely become more serious. Madara's influence would probably make him less impulsive. For instance, he would think twice before charging into battle without a proper plan.
If trained by Kurenai, Naruto could develop a more fluid and evasive fighting style. Kurenai is good at moving around undetected and quickly changing positions. Naruto could pick up on this and combine it with his own speed and agility. His movements in battle could become less predictable, making it harder for his opponents to land a hit on him. Also, he might start using genjutsu - enhanced taijutsu, where he uses illusions to misdirect his opponent's defense while delivering a physical blow.
His confidence might increase even more. Female Madara is a strong figure, and being trained by her would give Naruto a sense of having access to greater power. So he would be more self - assured in his actions.
If Hashirama had a more difficult upbringing, perhaps he would be less trusting and more cynical. His relationship with Madara might be more strained from the start. He might see Madara's ambition as a threat rather than a friendly competition. For example, if Hashirama had to struggle for basic resources as a child, he would be more protective of what he has and less willing to share with Madara's clan.
If Naruto was their grandson in fanfiction, his power level would likely skyrocket. He could gain access to the Wood Style more easily, like Hashirama. And he might have a natural understanding of the Sharingan and its powers from Madara. This would change the way he approaches battles and how others view him.
