Well, first of all, Naruto would have to adjust his stance and movement. With a claymore sword, he would need more space to swing it effectively. So, his battlefield awareness would increase. He would also start using the weight and length of the sword to his advantage. For example, he could use the sword's long reach to keep enemies at a distance while he prepares a ninjutsu attack. His fighting style would become a blend of traditional sword fighting techniques and his unique ninja skills.
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.
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.
It changes a lot. Naruto is known for his energetic and up - close brawling in the original. With a gun, he has to be more strategic. He might have to hide and take cover, which is different from his usual in - your - face fighting. Also, he could combine his jutsu with the gun, like using a wind jutsu to enhance the bullet's speed or trajectory.
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.
In the fanfic, the cane could be a conduit for his chakra. Naruto might be able to channel his chakra through the cane and use it to perform new jutsus. For example, he could strike the ground with the cane and send out chakra - powered shockwaves. This would change his fighting style by giving him a new way to attack from a distance without relying solely on his regular ninjutsu.
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 definitely change. He'd become more reliant on the weapon, which might make him seem more like a swordsman in addition to being a ninja. His confidence might also increase as he masters new techniques with Myrtenaster.
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 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.
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.
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.
