Well, perhaps Naruto takes Zabuza's sword and it becomes a symbol of his growth. He may face challenges from those who think he's unworthy of possessing such a weapon. Also, he could modify the sword to better suit his fighting style, like adding some of his own chakra -infused elements to it.
Maybe he defeated Zabuza in a battle and took it as a trophy.
The story could explore how Naruto adapts to having a weapon like Zabuza's sword. Since Naruto is used to his own hands - on combat and ninjutsu, the sword would be a new addition. He would have to train to master it. Maybe he'd seek out old friends or allies of Zabuza to learn more about the sword's history and proper use. This could open up new storylines and relationships for Naruto in the fanfic world.
One possible consequence could be that Naruto gains a new and powerful weapon. This sword might have unique abilities that could enhance his combat skills. He could use it to intimidate his enemies or as a last - resort weapon when his regular jutsu are ineffective.
Well, if Naruto gets Zabuza's sword in the fanfic, it could change his entire approach to battles. Zabuza was known for his swordsmanship skills. Naruto might start training with the sword under the guidance of someone like Kakashi. He could learn to infuse his chakra into the sword, creating new and powerful attacks. Maybe he would even develop his own special jutsu that combines the sword and his existing ninjutsu.
Another plot could be that Zabuza's sword ends up in the hands of an enemy of Konoha. Konoha sends a team of ninjas, including some of the younger generation like Naruto and his friends, to retrieve it. Along the way, they learn about Zabuza's legacy and the true strength of the sword. They have to battle the enemy who has already started to unlock some of the sword's powers, but in the end, they manage to get it back and decide what to do with such a dangerous weapon.
In such a fanfic, Naruto might have to carry out Itachi's mission to protect Konoha in a different way. He may use his own unique ninja skills and positive attitude to face the Akatsuki. For example, instead of using Itachi's Sharingan techniques, he would rely on his Shadow Clone Jutsu and Rasengan variations.
In a fanfic where Naruto takes Nagato's eyes, he might gain new and powerful abilities. For example, he could potentially access the Rinnegan's powers more directly. This could make him even stronger in combat, perhaps allowing him to use abilities like the Six Paths Techniques with greater ease. It could also change his relationships with other characters. Some might be in awe of his new power, while others could be afraid or jealous.
One possibility is that Naruto could learn new combat techniques from Zabuza. Zabuza was a highly skilled swordsman, and his fighting style was very different from what Naruto was used to. Naruto might adapt some of Zabuza's stealth and assassination skills, which could make him a more versatile fighter in future battles.
In a fanfiction where Naruto is trained by Zabuza, Naruto would gain a whole new perspective on fighting. Zabuza's style is very different from what Naruto has learned so far. Zabuza could teach Naruto about the importance of misdirection in combat, like how he uses the mist to hide his movements. Naruto might also pick up on Zabuza's ability to analyze an opponent's weaknesses quickly. This training could potentially make Naruto a more well - rounded fighter, able to adapt to different situations more easily. However, he would need to be careful not to let Zabuza's more cut - throat approach overtake his own kind - hearted nature.
A minor character like a blacksmith's apprentice could find Zabuza's sword. Instead of using it for fighting, they study it closely. They discover a unique metal alloy in the sword that they use to create new and improved weapons for their village. This not only changes their own fate as they become a renowned blacksmith, but also the fate of the village as they now have better weapons to defend themselves.
