Naruto's fighting style would likely become more stealth - oriented. Since Obito is known for his ability to move undetected, he might teach Naruto some techniques to blend into the shadows and surprise his opponents. For example, Naruto could learn to use the environment to his advantage in a more subtle way, rather than his usual straightforward attacks.
Naruto might also start using genjutsu more often. Obito has experience with genjutsu, and he could train Naruto to break free from genjutsu more easily as well as use simple genjutsu to deceive his enemies. This would add a new dimension to Naruto's fighting style, making him more unpredictable. He could use genjutsu to create distractions before launching a powerful Rasengan or a new jutsu that Obito has taught him.
His use of Rasengan could also change. Obito might teach Naruto how to infuse different elements into the Rasengan more effectively. Maybe Naruto would start creating new versions of the Rasengan, like a lightning - infused Rasengan for faster attacks or an earth - infused Rasengan with more destructive power. Also, Naruto's taijutsu would improve as Obito could teach him some of the Uchiha clan's unique hand - to - hand combat techniques.
Naruto's fighting style would likely become more refined. With Sakumo's training, he might start using more precise jutsu instead of his usual brute - force attacks. He could also incorporate more strategic movements, like better use of the terrain and stealth.
Naruto's fighting style would change significantly. He would no longer rely solely on his brute strength and Rasengan - based attacks. The Sharingan would allow him to see the flow of chakra more clearly, so he could target his opponents' weak points more precisely. He could also use genjutsu, which he has little experience with before. Maybe he would combine his shadow clones with the Sharingan's abilities, for example, having clones with Sharingan - enhanced vision to scout the area better during a battle.
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.
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.
Well, Kakashi might introduce Naruto to more strategic ways of fighting. For example, he could teach Naruto how to better analyze his opponents before attacking. Naruto, who was previously more impulsive, may start to hold back and look for the right moment to strike, like Kakashi does with his Sharingan.
Naruto might become more calculating. Urahara is a very strategic person, and under his training, Naruto could start thinking more before acting. For example, instead of just rushing into a fight, he'd analyze the situation first.
Naruto's morality could be somewhat skewed. Orochimaru has a very different view on right and wrong compared to Naruto. So, Naruto might start to question some of his previous beliefs. For example, he might be more willing to use dangerous or forbidden jutsus if it means achieving his goals. He'd also probably be more distrustful of others, as Orochimaru always has ulterior motives. This would be a big change from the Naruto who was always so quick to trust and befriend people.
Obito's influence would likely make Naruto more aware of the darker side of the ninja world. Naruto is usually very optimistic, but with Obito's guidance, he would see the hardships and betrayals that can happen. For example, Naruto might become more cautious in his trust of others.
Naruto might incorporate more stealth elements from Oliver Queen. His usual in - your - face combat style could become more calculated, with Naruto using the environment to his advantage just like Oliver does with his archery. He may also start using projectiles more effectively, similar to Oliver's arrows.
Naruto's fighting style might incorporate more of Killer Bee's unique techniques. For example, he could start using some of Bee's swordplay skills if he's trained in that. Also, Naruto might adopt a more fluid and acrobatic fighting style similar to Bee's. His use of chakra could become more refined, like how Bee can use his Tailed Beast chakra in creative ways.
