He would probably add more slashing and thrusting motions to his attacks. Instead of relying solely on his shadow clones and rasengan, he could use the sword for close - range combat and combine it with his ninjutsu. For example, he could channel chakra through the sword to create a more powerful slash or use it to deflect incoming attacks more effectively.
The addition of a sword would likely make Naruto's fighting style more balanced. Currently, he is very strong in long - range attacks with his rasengan variants and in using his shadow clones for various strategies. With a sword, he would have a reliable and deadly option for close - range combat. He might start to develop new techniques that involve both the sword and his chakra control. For instance, he could create a chakra - infused sword beam or use the sword to enhance his taijutsu strikes. This would not only change the way he fights individual opponents but also how he approaches group battles, as he now has a weapon that can cut through multiple enemies at once.
Naruto's fighting style would become more versatile. The sword could be used as a distraction in battle. He could throw it towards an enemy, forcing them to dodge, and then use that moment to launch a surprise attack with his ninjutsu. Also, he could use the sword to perform acrobatic maneuvers, like using it to swing himself around and gain momentum for a stronger attack. This would make his fighting style more unpredictable compared to when he only used his hands and ninjutsu.
His fighting style would likely become more melee - focused. Naruto is used to fighting from a distance with his jutsu, but with Zabuza's sword, he would need to get up close and personal. He might start to combine his ninjutsu with sword strikes. For example, he could use a clone to distract an enemy while he closes in with the sword for a surprise attack.
If the Dragon Sword has special abilities, like being able to absorb chakra, Naruto's fighting style would change drastically. He could start using it to drain his opponents' chakra during battles. This would force him to get closer to his enemies, making his fighting style more aggressive and in - your - face compared to his usual ranged attacks.
His fighting style would become a blend of his original ninja techniques and the powers of Hyourinmaru. Naruto could use his clones to distract opponents while he uses Hyourinmaru to strike from unexpected angles. The ice powers would give him an advantage in certain terrains, like frozen landscapes. He would also have to learn to control the release of Hyourinmaru's power, which is different from his chakra control. This would lead to a more diverse and unpredictable fighting style.
His fighting style would become more versatile. Naruto is used to his shadow clones and Rasengan techniques. But with Samehada, he could add a whole new dimension. Samehada absorbs chakra, so Naruto could use it to drain his opponents' chakra during close combat. He might also be able to combine his own chakra with Samehada's absorption ability to create some unique attacks that are more about disabling the enemy's chakra system rather than just physical damage.
Naruto's fighting style would change significantly. The Master Sword is a melee weapon, and Naruto is not used to relying on such a weapon. He would have to learn new footwork and combat stances. He could start using the sword as an extension of his arm in close - quarters combat. Also, he could use his shadow clones to create diversionary attacks while he strikes with the sword from unexpected angles.
He might start using more sweeping and slashing motions. Instead of his usual close - range punches and kicks, he could use the scythe's long reach to keep his opponents at a distance. For example, he could swing the scythe in wide arcs to fend off multiple enemies at once.
His fighting style would become more melee - focused. Instead of relying solely on his ninjutsu and taijutsu, he would have to get in close with the claymore sword. He might develop new combinations, like using a clone to distract an enemy while he gets in a good sword strike.
Having a sword would likely make Naruto's fighting style more versatile. He could use it for defense as well as offense. Maybe he would learn new jutsus that are specifically designed to enhance the power of the sword, like infusing it with chakra to make it cut through stronger defenses. This would also change his strategic approach in battles, as he now has a melee weapon at his disposal.
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'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.
