Well, Naruto in fanfiction often acts like a ninja in terms of his stealth. He might be able to blend into the shadows of the forest so well that even the most experienced ninja have trouble detecting him. And when it comes to intelligence gathering, he could use his charm and friendly nature to get information from villagers or even other ninja without them realizing they are being pumped for intel. Another way is his combat adaptability. He can quickly analyze his opponent's fighting style in a fanfiction battle and come up with a unique strategy on the fly, which is a very ninja - like trait.
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. He might start making jokes about his own shortcomings, which is not something he usually does. His interactions with characters like Sasuke and Sakura would become really different. 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 a 'naruto acts like gin fanfiction', Naruto might be quieter and more observant. Instead of his usual boisterous self, he could be more like Gin, who is often sly and calculating. Maybe he would have a more subdued way of showing his power and a different approach to his enemies.
One possible plot could be that Naruto starts adopting Deadpool's fourth - wall - breaking style. He might make jokes about his own story, like how he's always chasing Sasuke and how it's like an endless loop. For example, he could look at the reader and say something like 'You think I'll catch him this time? Maybe, maybe not!'.
One possible plotline could be Naruto getting some of Kaneki's ghoul - like powers. So he has to deal with the hunger for human flesh in a way that's similar to Kaneki's struggle, but in the Naruto universe. Maybe he tries to resist it while still protecting his village.
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. He could inspire his comrades not through big, rousing speeches all the time, but through his calm and collected actions, showing them that he has a plan and they can trust him to lead them to victory.
The fanfiction could explore Naruto being in a situation where he has to act like Madara to deceive the enemy. He gradually gets too deep into the role and starts to actually think and act like Madara on a more permanent basis. His friends notice the changes in his personality, like his increased aggression and his new - found belief in power as the ultimate factor in achieving goals. They then try to bring the old Naruto back.
One possible plot could be that Naruto, after being exposed to some strange chakra or magic, starts to take on Grimmjow's aggressive and fearless attitude. He might become more impulsive in battle, like Grimmjow, and start to challenge his enemies without much thought for strategy at first. His friends would be confused by this sudden change in his behavior.
Well, one possible plot could be that Naruto starts to adopt Pain's view on justice. He might see the world as a place full of suffering that needs a radical change. He could begin to question the traditional ways of the Hidden Leaf Village and try to implement some of Pain's ideas in a more positive way, like finding a new system to ensure peace that doesn't rely solely on the power of the ninja villages.
