He would likely become more confident. With the power of a dragon, he'd have a new source of strength. He might be less hesitant in battles.
His sense of identity would be greatly affected. Instead of just being a ninja with a tailed beast, he now has a whole new part of himself to figure out. He might struggle with self - acceptance, but once he does, he could transform into a more assertive and powerful version of himself. His values might shift a bit too. For example, he could develop a stronger sense of justice, inspired by the mythical and powerful nature of dragons.
His relationship with Sasuke would be very interesting. Sasuke might be initially suspicious of Naruto's new form, but eventually, they could bond over Naruto's struggle to control his powers and use them for good. It could be a new level of rivalry and friendship.
Naruto's character development would be quite a journey. At first, he'd be confused and a bit scared of his new powers. He might accidentally lash out with his hollow powers and feel guilty. But as he meets others with similar powers or knowledge of the spirit worlds, he starts to accept himself. His development would also be about learning the limits and capabilities of his powers. He might develop new jutsus that combine his ninja techniques with his shinigami and hollow abilities. His character would also grow in terms of leadership. He could lead a group of beings from different worlds, using his unique perspective to bridge gaps between them, all while still maintaining his core values of friendship and loyalty.
Naruto's character might become more brooding and mysterious, like the Undertaker. He would lose some of his usual exuberance and become more focused on intimidation. Instead of his loud and energetic self, he would be quieter, with a more menacing presence.
In this fanfiction, Naruto would grow in terms of his understanding of the world. Since he's half - ghost, he'd be exposed to different realms and beings. This would make him more adaptable and open - minded. His relationships with his friends would also change. He'd have to explain his new self to them, and in doing so, he might become more patient and understanding. For example, Sasuke might initially be skeptical but Naruto would have to find a way to make him see the potential of his half - ghost abilities.
In this fanfiction, Naruto's relationships would be transformed. With his old friends like Sakura, she might be both scared and curious about his dragon form. Naruto would also have to form new relationships with dragons. Some dragons might be hostile towards him because he was once a human. But he could also find some dragon friends who accept him for who he is. His relationship with his sensei, like Kakashi, could also change as Kakashi has to deal with Naruto's new identity and powers.
In fanfiction, if Naruto is half - bijuu, his appearance could change in several ways. His ears might be a bit pointed, like those of a fox if it was related to the Nine - Tails. There could be a faint glow around him, especially when he gets angry or uses his bijuu - related powers. His nails could be longer and stronger, like claws. And his gait or the way he moves might change, becoming more like the way the bijuu moves. He might even have a faint, beast - like growl in his voice at times, which would be a very distinct change in his appearance and the way he presents himself.
Naruto could also become more powerful but in a different way. His chakra might be tainted with a touch of the demonic, giving him new abilities that are both a blessing and a curse. He has to learn to control these new powers, which might make him seem more withdrawn as he trains in isolation to avoid hurting others accidentally.
Naruto would probably have a more complex view of power. In the original, he was all about becoming stronger to protect his friends. But as a Darkseid clone, he might question the nature of power. Darkseid uses power for domination, and Naruto would have to struggle not to be influenced by that aspect while still using his new - found powers for good.
Naruto would likely become more stealthy. Itachi is known for his stealth and if he trains Naruto, Naruto would pick up some of those skills. He might start to rely less on his brash and straightforward fighting style and incorporate more subtlety.
Naruto's character would change a great deal. Since Acnologia is a powerful and somewhat menacing figure, Naruto would probably be more aggressive. He might not value the same things as the original Naruto, like the bonds of friendship within the village. Instead, he could be more focused on his own strength and survival. He might also be more distrustful of others, having grown up under the tutelage of someone like Acnologia.
