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.
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.
Well, one possibility is that Naruto gets Zabuza's sword and tries to master its use. He might face challenges in understanding the unique abilities of the sword. Maybe he initially struggles to wield it properly because it's a different type of weapon compared to his usual ninja tools. But as he trains with it, he discovers new fighting techniques and becomes more powerful.
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.
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 plot could be Naruto learning Zabuza's unique water jutsu techniques. For example, he might master the Hidden Mist Jutsu which Zabuza was famous for. This would give Naruto an edge in combat, especially in stealthy attacks.
One possible plot could be that Naruto uses his shadow clones in a really unexpected and spooky way to scare Zabuza. For example, he could make the clones appear out of thin air in a dark and misty forest where Zabuza is. The clones could make strange noises and movements that Zabuza has never seen before, making him feel uneasy. Since Zabuza is used to being the one who instills fear in others, Naruto's sudden scare tactics would throw him off balance.
One possible plot could be that Naruto meets Zabuza's apprentice during a mission. The apprentice, having grown up with Zabuza's teachings, initially has a rather cold and ruthless attitude. Naruto, with his usual optimistic and friendly nature, tries to befriend the apprentice. This could lead to the apprentice slowly changing their views on life and friendship, and perhaps they end up joining Naruto on his journey to protect the village.
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.
Good writing style also matters. The descriptions of the sword, like its appearance and the way it cuts through things, should be vivid. If the author can make you feel like you're right there in the Naruto universe, watching the sword in action, then it's a great fanfic. Also, it could explore the backstory of the sword in more detail than what was shown in the original series, which would make it really engaging for fans.
