In the 'naruto acts like a cat fanfiction', a plot could be that Naruto befriends a group of stray cats in the village. They teach him their ways, and he in turn, protects them from the meaner villagers. As he acts more like a cat, he starts to understand their language, sort of like a telepathic connection. This connection helps him gather intelligence from all the places the cats can go, which he then uses in his ninja duties. This would be an interesting way to show Naruto's kind heart and his ability to adapt to new situations.
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!'.
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.
Sasuke could be an important character. He might be initially confused and a bit annoyed by Naruto's cat - like behavior, but as the story progresses, he could start to find it endearing or even useful. Another character could be Kakashi. He would probably be the one trying to figure out what caused Naruto to act this way and how to reverse it, if needed.
A really interesting plot twist could be that Naruto's Dante - like behavior is actually a result of a genjutsu cast by a hidden enemy. As he acts more and more like Dante, his friends start to suspect something is wrong and have to figure out how to break the genjutsu without harming Naruto.
Well, it could be about Naruto adopting Kisuke's laid - back yet intelligent attitude. Maybe he starts dressing in a more Kisuke - like style, with a long coat and a hat. He could also start using some of Kisuke's signature moves or strategies in battles, like using gadgets or outsmarting his opponents in a very Kisuke - esque way.
One possible plot could be that Naruto, for some reason, decides to adopt Sasori's more calculating and detached approach to combat. He might start using puppets or puppet - like techniques in battles, much like Sasori did. Maybe he's on a mission where he has to infiltrate an enemy base and he thinks acting like Sasori would be the best way to succeed.
One plot point could be Naruto forming a new kind of ninja group similar to Whitebeard's crew. He could gather ninjas with different skills and backgrounds, and they would operate based on a new set of values inspired by Whitebeard. For example, loyalty would be highly prized.
Well, in this fanfiction, perhaps Peter Parker begins to mimic a spider's hunting behavior. Instead of just using his powers to fight crime in the traditional way, he starts to stalk his enemies from the shadows, waiting patiently for the perfect moment to strike. He could also use his webs to create elaborate traps, like a spider does for its prey. This would give a whole new and interesting dynamic to his crime - fighting adventures.
