He would probably be more powerful in different ways. Hiruko might teach him unique and dangerous techniques that change his fighting style. Also, his personality would be shaped by Hiruko's teachings. Maybe he'd be more calculating and less impulsive. Instead of charging into battles head - first, he'd think more strategically like Hiruko. His sense of justice might also be warped. What he considers right and wrong could be different from the original Naruto who was influenced by the values of the Hidden Leaf.
If Naruto was raised by Hiruko, his view of the ninja world would be completely different. He wouldn't have the same sense of loyalty to the Hidden Leaf village as in the original story. Hiruko's own views and experiences would color Naruto's perception. Naruto might see the world as a place full of opportunities for power rather than a place to protect and uphold values. His relationships would also change. He might not have the same friends or might view his friends in a different light. For instance, he could see them as either allies in his pursuit of power or obstacles to overcome.
Well, it could be that Naruto, under Hiruko's influence, might develop a very different set of skills. Maybe he'd be more attuned to darker jutsus. He could also have a more cynical view of the ninja world.
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 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 He has to learn to control these new powers, which might make him seem more withdrawn as he trains in isolation to avoid hurting others accidentally.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.
Naruto might become more conflicted. Since Madara had some extreme views, Naruto would have to grapple with those ideas. He could become more secretive as he tries to understand Madara's motives better without alarming his friends. For instance, he might start training alone more often to study Madara - inspired 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.
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.
