His relationships with others could change. Some characters might find his rabbit ears cute and be more protective of him, while others might see it as a sign of weakness. Naruto would have to navigate these new social dynamics. For example, Sakura might mother him more, while Sasuke could be either indifferent or secretly intrigued. Over time, Naruto would have to learn to use his new - found attention (both positive and negative) to his advantage in his journey to become a better ninja.
Naruto could become more in - tune with nature. Since rabbits are often associated with nature, having rabbit ears might give him a deeper connection to the natural world around him. He could start to understand the language of animals better or be able to sense changes in the environment more easily. This would add a new dimension to his character and his ninja skills.
With Sasuke, it could be interesting. Sasuke might view Naruto's fox ears as a sign of his growing power and be both envious and intrigued. Their rivalry could take on a new dimension as Sasuke tries to understand how Naruto got this new ability and if he can gain something similar.
Naruto might become more confident earlier. With a brother by his side, he would have someone to rely on and confide in from the start. This could make him less of an outcast in his own mind and more willing to open up to others in the village.
His relationship with Sasuke might become more competitive. Sasuke would see Naruto's new fox - like features as a sign of his growing power and want to surpass him even more. Naruto, on the other hand, might feel a bit self - conscious around Sasuke at first.
His sense of family would be stronger. Naruto has always longed for family, and having an older brother would fulfill that to some extent. This could make him more empathetic towards others who are also missing family members. He might also be more cautious in battles, as he wouldn't want to let his brother down.
His self - confidence might change. On one hand, having this new powerful ability from the Gura Gura Fruit would boost his confidence. But on the other hand, he would also realize that he has a huge responsibility with these powers. He might become more introspective, thinking about how to use the power for good and not let it corrupt him, like how he was always careful with the power of the Nine - Tails inside him.
With Sakura, she might be a bit more protective at first. She could see Naruto as more vulnerable because of his new features that make him stand out. But as time goes on, she would also rely on him more in battles as his fox - like abilities prove useful.
Naruto might become more brooding. Sasuke's eyes are often associated with his more complex and sometimes darker emotions. With those eyes, Naruto could start to see the world in a different light, one that's perhaps more cynical. He might also become more isolated as he tries to figure out the new powers on his own, not wanting to burden his friends with his confusion.
Naruto would become more cunning. Orochimaru is a very sly character, and his training would likely rub off on Naruto. Naruto would no longer be as straightforward in his battles and interactions. He might start to think several steps ahead, like Orochimaru does.
His relationship with Sasuke could be affected. Sasuke might be initially intrigued by Naruto's new look but also see it as a sign of Naruto getting stronger without him. This could fuel his rivalry even more.
His relationship with Sasuke might change. Sasuke might be more intrigued by Naruto's new form. He could see it as a sign of Naruto getting stronger in a different way. They might start to train together again to see if Sasuke can also develop some unique abilities. With Sakura, she might be more protective at first. She'd worry that Naruto's new features could make him a target. And Naruto would have to reassure her that he can take care of himself.
