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.
The plot could start with Naruto having strange dreams or visions related to his hollow and shinigami halves. He begins to notice that he has abilities that no other ninja has. His training then takes a different turn as he tries to understand and master these new powers. Maybe he discovers that his parents had some connection to the spirit worlds, which is why he has this unique nature. He then gets involved in a conflict between the forces of the hollows and the shinigami. With his ninja skills combined with his newfound powers, he has to find a way to broker peace or at least stop a war that could destroy all the worlds he cares about.
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.
Naruto would probably be more independent in his thinking. Instead of relying on the typical ninja values taught in the village, he'd draw from the Shinigami's teachings. This could make him a bit of a rebel in the eyes of the ninja community. He might question the established norms more often. His development would also be influenced by any special tasks or missions the Shinigami gives him. For instance, if he has to deal with restless souls, it would make him more empathetic towards those in pain, but also more determined to maintain the order between the living and the dead.
The half - brother could be developed as a character with a troubled past. He might have been ostracized in his own community because of his relation to Naruto or his own unique abilities. This could make him initially cold and distant but as he interacts with Naruto, he could gradually open up and become more warm - hearted.
Naruto could start as a confused character, struggling with his newfound identity. His usually sunny and determined personality might be overshadowed by fear and doubt at first. As he gets used to his powers, he could become more confident but also more complex, having to balance the good and evil within him.
In 'naruto shinigami hollow fanfiction', a frequently seen theme is the fusion of different power systems. Naruto's ninja skills combined with Shinigami's death - related powers and Hollow's reiatsu - based abilities. This creates a complex and interesting power dynamic. Additionally, the theme of redemption can be present. Maybe Naruto has to redeem himself in the eyes of his village after getting these strange powers that initially seem dangerous. And of course, the theme of adventure is common, as Naruto goes on new quests to understand and master these powers.
Naruto's character might become more self - reliant. With no family support, he has to depend on his own wits and skills. So he becomes better at making quick decisions and solving problems on his own.
Sure, there are probably fanfictions with this concept. Fanfic writers are known for their creativity in crossing over different fictional worlds. A 'Naruto is half Saiyan' story could explore how Naruto's life and the Naruto - verse in general would be affected. For example, how would his relationships with his friends and enemies change? How would the ninja world react to his new Saiyan abilities? It could also delve into the backstory of how he came to be half Saiyan, perhaps some kind of inter - dimensional or time - traveling event.
In fanfiction, if Naruto is half - bijuu, it could mean he has enhanced physical abilities. For example, he might have greater strength and speed like a full - bijuu. His chakra reserves could also be much larger, allowing him to perform more powerful jutsu for longer periods.
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.
