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.
If Naruto turns into the Nine - Tailed Fox in the fanfiction, his character development would take a very different turn. He would no longer be just the optimistic, loud - mouthed ninja we know. As the fox, he'd have a more primal and instinctual side. This could make him more isolated at first, as his friends may not understand him. But through his journey of learning to co - exist with the fox's nature, he could develop a deeper understanding of the world and himself. He might gain a new sense of purpose that is not just about becoming Hokage, but also about finding harmony between his human and fox - like selves.
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.
One way is to show how the transformation affects his relationships. Maybe his friends start to see him in a new light, and he has to work hard to maintain those relationships. He could learn more about loyalty and friendship as he tries to prove that he's still the same Naruto, even with the power of the Nine - Tailed Fox. This would enhance his character development in terms of his social and emotional growth.
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.
Well, if Naruto turns into the nine - tailed fox in a fanfic, it would be really cool. He would likely be almost uncontrollable at first, as the power of the nine - tailed fox is so immense. But as the story progresses, he could learn to harness that power. His friends might be both in awe and a bit scared of him. And he could use the nine - tailed fox's abilities like its tails for attacks and its natural cunning in combat situations.
When it comes to Sasuke, the Nine - Tailed Fox Faunus could be seen as a threat at first. But as the story progresses, they might find common ground in their pursuit of power and their desire to protect their own kind. The faunus could show Sasuke a different side of power, one that is more in tune with nature.
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.
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.
Well, his character development could take a whole new turn. Eren is known for his aggression and determination as a male. As a girl, he might have to find new ways to express those traits. He could become more empathetic as he experiences different forms of discrimination or treatment. Also, his relationships with his male friends could become more complex. They might see him in a new light, and he might have to re - evaluate his own self - worth in relation to how they now view him. His development could also be influenced by how he copes with his new physical form and the limitations or advantages it might bring in the fight against Titans.
