The character development would be quite drastic. Naruto would start to lose his naivete and become more world - weary. He would stop believing in the good of everyone so easily as he used to. His interactions with his enemies would change from trying to understand them to simply seeing them as obstacles to be removed. This is a big shift from his normal character who always tries to find a way to redeem his foes.
In this fanfiction scenario, Naruto's character development would be a complex journey. Initially, he would struggle with this new persona. He has been so used to being the loud, energetic Naruto. But as he continues to act like Sesshomaru, he would start to understand the benefits of being more reserved and calculating. His view of the ninja world would change. He might see the shinobi hierarchy in a different light, perhaps more like Sesshomaru views the demon - youkai world. His growth would not only be in terms of power but also in how he perceives the world and his place in it, which is very different from his original character arc.
In a fanfiction where Naruto acts like Sesshomaru, the dynamic in the Naruto universe would be completely shaken up. Naruto's relationships would be the most affected. His friends like Sakura and Kakashi would be at a loss as to how to deal with this new Naruto. He would no longer be the one to quickly jump into a fight without thinking. Instead, he would assess the situation more carefully, like Sesshomaru. His appearance might not change much, but his aura would be completely different. He would carry himself with an air of superiority and detachment, which would be a huge contrast to his normal self.
His character development would be very different. Naruto usually grows through his bonds with others, but if he acts like Alucard, he may grow through solitude and self - discovery in a more menacing way. He could start to view his enemies as mere prey rather than people with their own motives. His ninja way might change from believing in hard work and friendship to believing in the strength of the self and the power within, which is a more Alucard - like philosophy.
Well, if Naruto acts like an Uchiha in fanfiction, his character development could be very different. Uchihas are often known for their brooding and more introverted natures compared to Naruto's original outgoing self. He might become more focused on power and revenge, like some of the Uchihas. His relationships would also change. For example, his bond with Sasuke might be less about rivalry and more about a shared Uchiha - like identity. He could also start to use Sharingan - like abilities, which would change the way he approaches battles and his overall growth as a ninja.
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.
When Naruto acts like Jiraiya in fanfiction, his development would be a blend of his own self and Jiraiya's traits. Naruto is very goal - oriented, but with Jiraiya's influence, he could become more of a wanderer, exploring the world more freely. His combat style might also change. Jiraiya was a master of many techniques, and Naruto could start to incorporate some of Jiraiya's more obscure jutsu into his own fighting style. This would not only make him a more versatile fighter but also show his growth in a different direction compared to the original story.
In such a fanfiction, there could be a lot of cultural clashes. Naruto is used to the shinobi way of life, with its clans and ninja villages. Sesshomaru's world in 'Inuyasha' has its own set of rules regarding demons and humans. Naruto might try to bring some of his ninja ethics to this new world. There could also be a plot where Naruto has to prove himself to Sesshomaru's followers or enemies. His Naruto - style combat techniques would be a novelty in this world, and he could use them to his advantage while also learning new skills from his father and the other characters in the 'Inuyasha' world.
It could be really wild. Naruto's energetic and friendly nature would contrast with Sesshomaru's cold and aloof personality. Maybe there would be a story about how Naruto discovers his connection to Sesshomaru and has to navigate the Inuyasha world with his ninja skills.
Naruto's character would change a lot. He'd become more reserved perhaps, as Sesshomaru is a rather aloof character. But he'd also have a new sense of power and pride. His development could involve learning to control his new demon powers, which might be more difficult than his chakra control. He might start to view the world from a more demon - like perspective, seeing things in terms of power hierarchies more often.
One possible development is that Naruto becomes more composed. Minato was calm under pressure, and Naruto could inherit this trait. He might also become more of a loner at first as Minato was often on solo missions. But as he grows, he would learn to balance this solitude with his need for friends. His leadership skills would improve too, as Minato was a great leader.
Naruto's character would likely become more aggressive. Yujiro is a very aggressive character, and Naruto might start to show similar traits. He could be quicker to anger and more assertive in his actions.
