How can Naruto's character develop in a fanfic where he controls the Nine - Tails?

At first, Naruto would probably be excited about his new ability to control Grimm. He loves to show off his skills in the original series, and this would be no different. But as he gets deeper into it, he'd face challenges. For example, some Grimm might be more resistant to his control. This would force him to be more patient and strategic, which would be a new side of his character. He might also start to empathize more with the Grimm, understanding that they are just products of their world, much like how he understood the villains in his own world after learning their backstories.

Naruto's character might develop a deeper sense of self - awareness. With the Nine - Tails Cloak, he realizes he has a greater power and responsibility. He becomes more cautious in using it, understanding the consequences of losing control.

Well, initially, Naruto might show kindness towards the Nine - Tails despite it being a powerful and somewhat feared entity. He could try to communicate with it on a deeper level. The Nine - Tails, in turn, might be intrigued by Naruto's tenacity. As time passes, they begin to trust each other more. Naruto may share his dreams and fears with the Nine - Tails, and the Nine - Tails might start to see Naruto as someone worthy of its friendship.

Naruto might become more cautious. Dealing with the 12 - tails, which is likely extremely powerful, would force him to think before acting. He can't just rush in like he sometimes does.

In the 'naruto controls reality fanfic', Naruto's character development could be centered around his understanding of power. With the ability to control reality, he may start to question what true power really means. Is it about changing the world to fit his ideals, or is it about accepting the world as it is and making the best of it? This internal struggle could lead to significant growth in his character. Also, his relationships with other characters would change. Some might fear his new power, while others might try to take advantage of it. How he navigates these new dynamics would shape his character further.

He might become more self - aware. When Naruto goes 4 - tails, he often loses control. But in fanfictions, this could be a turning point for him to realize his own limits and the importance of self - control. So, his character could develop into a more cautious and less impulsive person.

To develop the baby nine - tails, it could be given a unique personality trait such as being very empathetic. So, it can not only feel Naruto's emotions but also those of other villagers. This causes it to try and bridge the gap between Naruto and the villagers who fear it. It might go out of its way to show the villagers that it means no harm, which in turn would make for an interesting character arc as it tries to change the perception of the nine - tails in the village.

His character might become more isolated as he has to deal with the overwhelming power of the Ten - Tails. He would have to learn to control it on his own, which could make him seem distant to his friends.

He might become more brooding and introspective as he grapples with the new power's influence.

As Naruto controls headcrabs, he could develop a more complex view of the world. He'd see that there are different kinds of power sources and ways to interact with living beings. This might lead him to question some of the traditional ninja teachings. He could start to advocate for a more inclusive approach in the ninja world, one that doesn't immediately view strange or dangerous creatures as enemies but rather as potential allies or tools that can be controlled and used for good. His relationships with other characters could also change. Some might be afraid of his new power, while others might be intrigued and want to learn from him.
