In a fanfiction where Naruto acts like Gintoki, his sense of humor would change drastically. Gintoki has a very specific brand of humor that includes a lot of self - deprecation and poking fun at others in a good - natured way. Naruto, who is more of an optimistic and positive - minded character, would have to adapt to this new type of humor.

For example, he could tease Sasuke in a more sarcastic way rather than the usual friendly banter. This would add a whole new dynamic to their relationships.
In the 'naruto is like sasori fanfiction', they might share a sense of being outsiders. Naruto was an outcast as a child because of the Nine - Tailed Fox inside him.

Well, it could mean that Naruto might adopt Ulquiorra's cold and detached demeanor. He might start speaking in a more monotone way, like Ulquiorra. Also, his fighting style could become more calculated and less impulsive, similar to how Ulquiorra approaches battles in a very methodical manner.
In terms of leadership, Naruto could become more like Netero. Netero was highly respected in his world, and if Naruto adopted his style, he might be more reserved in his leadership but still very effective.
