Naruto's character would experience a significant shift. His carefree and energetic nature would be overshadowed by a sense of isolation. He'd be forced to deal with his newfound bloodlust, which would conflict with his moral code. His interactions with others would become more complex. He might find it difficult to trust people as he doesn't know who could be working for his vampire masters. His growth as a character would no longer be just about becoming a great ninja but also about breaking free from the chains of slavery and reclaiming his true self.
In this setting, Naruto would be more cautious. As a vampire slave, he's constantly in a state of vulnerability. He might lose some of his naivete and become more calculating. His loyalty to the village would be tested as his vampire masters could order him to do things against the village's interests. Also, his relationships with his friends like Sasuke and Sakura would change drastically. He might push them away at first to protect them from his new reality.
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 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 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 view of the world would expand greatly. If Naruto is a Xenophage in this fanfic, he would be exposed to different types of entities and powers that are not native to his world. This would make him more open - minded and curious. He would start to question the nature of his own world and the existence of other dimensions. His character would develop from a simple - minded, if brave, ninja to a more complex and philosophical figure, constantly seeking to understand the greater mysteries of the universe while still maintaining his core values of protecting his friends and village.
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 could develop a sense of pride that he didn't have before. This Super Saiyan 3 form is something extraordinary, and he might start to show it off a bit. But at the same time, he would also have to learn humility. If he becomes too arrogant, his friends might distance themselves from him. So he would be in a constant struggle between showing off his power and being the humble ninja he was raised to be. Also, his leadership skills might improve as he now has a power that others look up to, and he would need to lead by example when it comes to using this power responsibly.
Naruto's character change in this 'naruto buys a slave' fanfiction could be quite significant. Firstly, his initial innocence and naivete might be replaced with a sense of power and control. His relationships with his friends could also be strained as they may not approve of his actions. He might become more isolated as he tries to justify his new - found position as a slave - owner. Moreover, his self - image could be shattered as he has to confront the fact that he is engaging in an unethical practice, which could lead to a downward spiral of his character development.
It would make him more versatile. He's known for his Rasengan, but using the Chidori would show that he can adapt other powerful techniques. This could make him seem more of a prodigy, as the Chidori is a difficult technique.
His view on power could shift. Instead of relying solely on his own chakra and the Nine - Tails' power, he may start to consider other ways of obtaining and using power, similar to how Cell absorbs power from others. This could make him more open - minded about different forms of strength in the ninja world. He might also become more interested in biological or cellular - level forms of power manipulation, which is a big part of what makes Cell so powerful.
Naruto would likely become more confident. Knowing she is the daughter of a powerful god like Apollo would give her a sense of self - worth. She might also become more in tune with arts like music and poetry, which are associated with Apollo.
Naruto would likely be more cunning. Since Orochimaru is known for his devious ways, Naruto might inherit some of that. He could be more calculating in battles rather than just relying on brute force. However, he would still have his core of kindness. So, it would be an interesting mix of Orochimaru's slyness and Naruto's big - heartedness.
