When Naruto turns into the nine - tailed fox in fanfiction, his character undergoes a significant transformation. At first, he may seem like a completely different person. His usual optimism and cheerfulness are overshadowed by the fox's more primal and often darker emotions. But as time goes on, he begins to find a balance. He uses the fox's power not just for brute force in battles, but also to protect those he loves in more nuanced ways. His relationship with the fox also changes his view of himself. He no longer sees himself as just a regular ninja with a big dream, but as someone with a powerful and dangerous entity inside him that he must master.
Naruto's character changes in multiple ways. Physically, he has the power of the nine - tailed fox, which makes him more confident in a sense. But mentally, it's a struggle. He has to constantly fight the fox's instincts. He might start to isolate himself from his friends because he's afraid of hurting them. However, as he learns to control the transformation, he also becomes more mature. He realizes the responsibility that comes with this great power and tries to use it for the greater good of the village and his friends.
He becomes more aggressive. The nine - tailed fox's nature seeps into Naruto, so he's quicker to anger and more likely to lash out. For instance, he might not think as rationally as he usually does when making decisions in battle or in dealing with his friends.
His personality might become more aggressive. The nine - tailed fox's instincts could seep into Naruto, making him more likely to attack without hesitation. He could also become more solitary as the power might be overwhelming and he doesn't want to accidentally harm his friends.
He also has to deal with the public perception. People who are afraid of the nine - tailed fox might start to shun or even attack Naruto. And in battles, his enemies might target his connection to the nine - tailed fox, trying to force him to transform and lose control. He needs to be constantly vigilant about this.
His relationship with the villagers could become more complex. Some might see him as a greater threat, while others who have come to know Naruto as a hero might be more accepting. His transformation could also lead to new alliances as some might want to use his power for their own purposes, which Naruto would have to navigate carefully to protect his relationships.
It could make his friends more cautious around him. For example, Sakura might be a bit more hesitant to get close, fearing the power of the Nine - Tailed Fox. But at the same time, some like Sasuke might see it as an opportunity to become stronger by sparring with Naruto in this new form.
There are fanfictions where the Nine - Tailed Fox has a split personality. One side is the fierce and powerful beast, and the other is a more gentle and understanding entity. Naruto has to deal with both sides, which creates a very complex and different kind of relationship compared to the original series. This can lead to some really interesting character development for Naruto as he tries to balance and understand this unique relationship.
His character could become more instinct - driven. As a fox, he might be more in tune with his primal side, which could either make him more aggressive or more cautious depending on the situation. This would be a new aspect of his character development.
His character development would be more complex. He'd have to deal with the dual nature of being both Naruto and the Nine - Tailed Fox. He might become more aggressive at times due to the fox's influence, but also gain new insights and powers that could shape him into a more powerful and wiser ninja.
Well, in some fanfictions, Naruto might start his journey after a particularly intense battle where he realizes the full potential of the Nine - Tailed Fox's power within him. It could be a fight against a strong enemy that makes him understand he needs to control the fox's power to protect his friends and the village.
One interesting plot could be Naruto fully transforming into the Nine - Tailed Fox during a battle against a powerful enemy. His friends are initially shocked but then try to find a way to bring him back to his senses.
One possible plot twist could be that Naruto loses control over his transformation into the Nine - Tailed Fox in a completely unexpected situation. Maybe during a friendly spar with his friends, and this causes them to fear him in a new way. It would add a whole new layer of drama to their relationships.
