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 involve Naruto being sent to another dimension where he meets other half - Saiyan and half - Kryptonian beings. There, he learns more about his unique heritage and how to fully utilize his powers. He then brings this knowledge back to his own world. With his new - found abilities, he can not only fight stronger enemies but also bring about a new era of peace and cooperation between different clans and villages in the Naruto universe. He might also face some who are jealous of his powers or fear them, adding more conflict to the story.
It could be a powerful ninja who has made a deal with an otherworldly force to gain powers to match Naruto's. This antagonist might be jealous of Naruto's unique heritage and wants to prove that pure ninja power is superior. So, he uses dark magic or forbidden jutsu to become a formidable foe.
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.
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.
One possible plot could be that the Kryptonians and Saiyans initially clash due to a misunderstanding. The Saiyans, known for their love of battle, might see the Kryptonians' powers as a threat to their dominance in the universe. As the war progresses, a few individuals from each side start to realize that they have more in common than they thought. For example, both races possess great strength and a warrior spirit. Eventually, they could team up against a greater evil that threatens both of their home planets.
It could be about Naruto discovering his Saiyan heritage. Maybe he starts to notice strange powers emerging within him that he can't explain with ninja techniques. This leads him to uncover a hidden part of his past that involves his Saiyan side.
One possible plot could be Naruto discovers his half - angel, half - demon fox nature during a life - threatening battle. His angel side gives him the ability to heal and purify, while his demon fox side provides immense power. He struggles to balance these two sides as he faces powerful enemies who are either attracted to or threatened by his unique nature.
In a 'naruto is half ghost' fanfiction, the plot might center around Naruto's struggle with his dual nature. He could be shunned by some in the village who fear his ghostly side.

Well, one possible plot could be that Naruto has to adapt his fighting style. He might rely more on his other senses like hearing and smell. For example, he could develop new jutsus that are more focused on sensing the enemy's chakra without having to see clearly. He may also form closer bonds with his friends who would help him in combat and daily life, like Sakura using her medical skills to find ways to potentially improve his vision or at least help him deal with the challenges of being half - blind.
One possibility is that Harry would have superhuman strength and speed like a Saiyan. He could use his new powers to defeat Voldemort more easily. For example, in a battle, he could move so fast that Voldemort's spells can't touch him, and his powerful punches could break through dark magic defenses.
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.
