His character would develop a darker edge. He would have to constantly battle his new - found bloodlust. This could make him seem more distant at times. However, he would also become more empathetic towards outcasts, like how vampires are seen in the ninja world. He might start to question the ninja society's quick judgment of things that are different, just as he has always been different himself. His values would still be there, but his approach to achieving them would change. He might use his vampire powers in a more stealthy way compared to his flamboyant ninja techniques.
Naruto would become more brooding. His usual sunny disposition would be tempered by the knowledge of his vampire side. He'd be more cautious about his relationships, fearing he might accidentally harm his friends. For example, he might be hesitant to get too close physically during hugs or high - fives in case his vampire strength gets out of control.
His character would have a darker edge. The vampire nature could bring out a more primal and possessive side. And the Rinnegan would give him new levels of power and knowledge. He might start to question his old values as he realizes the potential of his new powers. He could become more solitary, training alone to master his combined abilities rather than relying on his friends like he used to.
Naruto's character would change in several ways. His sense of loyalty would be tested. As a vampire, he might be more tempted to put his own needs (like finding blood) first. Emotionally, he could become more brooding. He's used to being the energetic one, but now he has to hide his vampiric nature. This could lead to him distancing himself from his friends. Also, his ninja skills would take on a different aspect. His stealth might improve because he has to move in the shadows more, but his use of some jutsu that require sunlight or open areas could be compromised.
Naruto would become more brooding. His usual cheerful self would be dampened by the dark nature of being a vampire slave. He'd be more secretive as he has to hide his new condition from his friends at first.
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.
Naruto's life would be completely different. He'd be part of a vampire family, which means different social norms and rules. He might not be able to be as open with his old friends as before. And he'd have to learn about vampire history and lore, which could be both fascinating and terrifying. His identity as a ninja would be in conflict with his new vampire identity in some ways, like when it comes to using violence. Vampires have their own way of dealing with threats that might not align with the ninja way.
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.
Naruto would likely become more solemn. The environment of hell is not a happy - go - lucky place like Konoha. He would have to be more strict and less naive. His usual exuberance might be toned down as he deals with the weight of ruling hell.
