When Naruto is portrayed as a 'feral child' in fanfiction, it changes his character significantly. His relationship with his inner self is likely to be different. Instead of having a clear - cut idea of who he is as a ninja, he might be more in touch with his basic animal - like self. His reactions to things can be more unpredictable. For instance, when faced with danger, he might not use the typical ninja tactics but rather something more instinctual like running away or hiding in an unexpected place. His bond with his mentors could also be affected. Instead of following their instructions blindly, he might question them more because his 'feral' nature makes him more independent - minded. Moreover, his understanding of chakra and jutsu could be more experimental. He might discover new ways of using his chakra based on his 'feral' experiences, which could lead to the creation of unique jutsu not seen in the original series.
In fanfiction, the 'feral child' concept can make Naruto more instinct - driven. He might rely more on his gut feelings rather than traditional ninja training. For example, instead of following a set jutsu sequence, he might improvise based on his immediate senses. This can also make him more of an outsider in the village. His different behavior and way of thinking might not be easily understood by the other villagers, which could lead to more conflict or misunderstanding. But it also gives him a unique charm as he is not the typical well - behaved ninja - in - training.
In fanfiction, when Harry is a 'feral child', it often makes him more independent. He doesn't rely on the normal support systems like other Hogwarts students. For example, he might not trust adults easily as he's had to fend for himself. This makes his relationships more complex, especially with Dumbledore who he may see as just another authority figure at first.
His communication skills could be affected. Instead of his usual witty banter, he might be more growls and short, sharp commands. This is because his feral side has taken over some of his human communication tendencies. Also, his relationships with others would shift. His friends might be a bit scared of this new side of him at first, but then try to help him come to terms with it.
In fanfiction, if Naruto is indestructible, it can make him seem more fearless. He doesn't have to worry as much about getting hurt, so he can take more risks in battles. For example, he might be more willing to face a powerful enemy alone.
The Chimera concept can make Naruto more complex. If he has chimera powers, he may become more cautious as he doesn't fully understand them at first. He might also be more isolated as others may be afraid of his new powers.
Naruto's character could become more patient. With immortality, he has all the time to wait for things to develop. For example, instead of rushing into a fight, he might wait for the perfect moment. Also, his view on life and death would change. He would no longer fear losing his loved ones in the same way as he knows he can't die. This could make him more empathetic towards those who are afraid of death.
The 'godlike hanyou' idea often makes Naruto more of an outcast in some fanfictions. People might be afraid of his new powers or misunderstand them. This can lead to Naruto feeling lonely at times, but it also makes him more determined to prove himself and show that his powers can be used for good. He has to learn to control his hanyou side and show others that he's still the same Naruto at heart, just with added abilities.
In fanfiction, the dark chakra can make Naruto more brooding. Instead of his usual optimistic self, he becomes more withdrawn as he struggles with the new power. For example, he may question his own identity and whether he can still be the hero everyone expects him to be.
Well, in the fanfiction, the sealed hatred could transform Naruto into a more complex character. He might start to question his own motives and actions more deeply. Since the hatred is sealed within him, he may feel like he's constantly at war with himself. This internal conflict could lead to him making different decisions than he would in the original story. He could become more hesitant in his actions, always considering the potential influence of the sealed hatred on his choices, which is a big departure from his more straightforward and impulsive nature in the main Naruto storyline.
It changes his fighting style completely. He no longer relies on his shadow clones and Rasengan. Instead, he uses his cold powers to freeze opponents or create ice barriers. This makes him a more strategic fighter. Also, his relationships with his friends might change. They could be a bit afraid of his new power at first, but as the story progresses, they learn to accept it. For example, Kakashi might have to train him differently to help him control this power.
It makes him more introspective. As an artist, Naruto has to look within himself to find inspiration. This leads to him being more in tune with his emotions rather than just his ninja skills.
