Their relationship would likely become more complex. They might start to protect each other more fiercely. For example, Sasuke might not leave the village in the first place because he now has a closer family tie to Naruto. Naruto would also be more insistent on getting Sasuke to stay and see him as an important part of his family.
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 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.
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.
One common theme is the struggle for identity. Naruto, with his half - angel half - demon nature, often has to figure out where he belongs. Another theme is power control. Balancing the angelic and demonic powers can be a huge challenge.
Well, it could be about Naruto having the powers of both Saiyan and Kryptonian. Maybe he can use Saiyan's ability to transform into a Super Saiyan and combine it with Kryptonian super strength, heat vision, etc. He could use these combined powers to protect the Hidden Leaf Village from a new kind of threat that no one in the Naruto universe has ever faced before.
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.
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.
One implication could be that Naruto has enhanced physical abilities. Angels are often depicted as strong and fast, so Naruto might have superhuman strength and speed. He could also have some sort of divine power, like the ability to heal or purify things. Another aspect could be his appearance. Maybe he has wings or a halo that he can hide or show at will.
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.
