Zabuza could be portrayed as more of a mentor figure. Instead of just being a ruthless assassin, he could be shown guiding Naruto in some aspects of combat or strategy. Maybe he survived his encounter with Kakashi and had a change of heart, and now he imparts his knowledge to Naruto who is now a sensei himself.
Zabuza could be quite cold to Naruto at the beginning. He's not exactly the warm - and - fuzzy type. But when Naruto shows his skills and tells his story of being banished unjustly, Zabuza might empathize on some level. He might not show it openly, but he could start to protect Naruto in his own way, perhaps because he sees a bit of his younger self in Naruto who was also wronged by the ninja system.
He could learn Zabuza's signature water - style jutsu, like the Hidden Mist Technique. This would give Naruto an advantage in terms of creating diversions and hiding his movements during battles.
On a more practical level, Naruto's skills might be misused. Instead of using his power to protect Konoha and the people he cares about, he's using it for Zabuza's self - centered motives. This could also make him a target for other ninja who oppose Zabuza. So not only is he in danger from the people he used to call friends, but also from new enemies. And if he ever tries to break free from Zabuza, he might face severe retaliation from Zabuza himself, which could be life - threatening.
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.
Well, Naruto is a very impressionable character. His idolization of Zabuza might make him more open to using unorthodox or morally grey techniques. He could start to question the black - and - white view of good and evil that he initially had. Maybe he would see the value in Zabuza's loyalty to Haku, which could in turn strengthen Naruto's own bonds with his friends.
Well, it could be due to some sort of mind - control jutsu. Maybe Zabuza uses a special technique that he learned in the Hidden Mist Village to make Naruto do his bidding.
There might be. Fanfiction is full of creative and sometimes unexpected ideas. This concept could bring a whole new dynamic to the Naruto story. It could potentially rewrite parts of Naruto's past, like if Zabuza was involved in his early life in some way. Or perhaps it could create a different kind of bond between Naruto and the Hidden Mist Village, since Zabuza was from there.
One common theme is the exploration of her strength. Since Zabuza is known for his power in the original Naruto series, in fanfiction with a female Zabuza, the focus is often on her being a formidable kunoichi. Another theme is her relationships. This could be her friendship with Haku, but re - imagined in different ways, like a sister - like bond or a more complex relationship.
