In this kind of fanfiction, Naruto's unique abilities like his shadow clones and rasengan could potentially be incorporated into the power of the zanpakuto. Maybe the zanpakuto would gain the ability to create multiple copies of itself, similar to the shadow clones, which could be used for both offense and defense. And the rasengan could be transformed into some sort of energy blast that the zanpakuto can release.
If Naruto becomes Yoruichi's zanpakuto, it would completely change the dynamic of battles. Yoruichi is already a very powerful character in the Bleach universe. With Naruto's spirit and powers added to the zanpakuto, she might become even more formidable. For example, Naruto's never - give - up attitude could influence the way Yoruichi wields the zanpakuto, making her more tenacious in combat. Also, the zanpakuto's form might change to incorporate some of Naruto's iconic features, like his orange jumpsuit color or his headband symbol.
One possible scenario is that the connection between Yoruichi and the zanpakuto (Naruto) would be very different from a normal zanpakuto - wielder relationship. Naruto, being a character with his own strong will, might communicate with Yoruichi in a more direct and opinionated way compared to a typical zanpakuto spirit. This could lead to some interesting internal dialogues during battles. Additionally, the training process for Yoruichi to master the new powers of the zanpakuto would be unique. She would have to learn how to combine her existing skills with Naruto's abilities, which could involve a lot of trial and error and character growth.
