Yes, there are likely some out there in the vast world of fanfiction. Fanfiction writers often come up with unique and unexpected crossovers like this. However, the quality and popularity can vary greatly.
At first, there might be some misunderstandings. Naruto is used to the shinobi world and its ways, while Superman is all about truth, justice, and the American way. But as they spend more time together, they would start to respect each other's strengths. Naruto would admire Superman's raw power, and Superman would be impressed by Naruto's strategic thinking and his ability to come back from tough situations.
It could be that the essence of Naruto's character is often misrepresented in Superman fanfiction. Naruto is about hard work, friendship, and achieving one's dreams through personal growth in his own story. When put into Superman fanfiction, his character might be forced to fit into plots that don't align with his original values, which could lead to the idea that he 'hates' such fanfiction.
In a fanfiction scenario, Superman's ability to fly could give Naruto a new perspective on combat. Naruto could learn to use the airspace more effectively. He might even develop new jutsu that are based on aerial combat, inspired by Superman. And Superman could learn from Naruto's ability to sense chakra. This could help him detect hidden threats or enemies that are using some form of energy cloaking device in his own world.
One interesting crossover could be Naruto learning about Superman's powers. Maybe Naruto is intrigued by Superman's ability to fly and his super strength. He might try to incorporate some of those elements into his own jutsu training. For example, he could study how Superman uses his strength in combat and adapt it to his taijutsu.
The different power scales. Naruto has his own progression of power through training and ninja ranks. Superman's power is on a completely different level like being able to move planets. In fanfiction, it might be hard to balance their powers in a way that makes sense to Naruto fans, so Naruto might seem to 'hate' it.
A 'Naruto kills Superman' fanfiction could be a complex and exciting read. Naruto would have to find a way to counter Superman's strength, flight, and heat vision. Maybe he would team up with some of his ninja comrades at first to study Superman's abilities. He could use his ninjutsu to create illusions and misdirect Superman. Once he figures out a strategy, perhaps using a combination of his most powerful jutsu like the Tailed Beast Bomb. It would also depend on the rules set in the fanfiction world, such as if there are any limitations on Superman's powers or if Naruto has any new abilities or enhancements. The story could also explore the moral implications of Naruto killing Superman, which could add depth to the narrative.
Well, in a fanfiction where Naruto is adopted by Superman, Naruto would be exposed to a whole new set of challenges and opportunities. He'd have to deal with the fact that he's now part of a world where people expect Superman - like behavior from him. His training as a ninja would be put to the test in different ways. For example, he might use his shadow clone jutsu to help Superman in situations where Superman needs to be in multiple places at once. And he would probably learn a lot about self - restraint and responsibility from Superman, which could make him an even better hero in his own world when he eventually returns.
He could develop the ability to combine his chakra with Superman's powers. For example, he might be able to use his Rasengan while flying at super - speed. Or he could infuse his chakra into his heat vision to make it even more powerful.
If Naruto had Superman's powers in fanfiction, it would change everything. His village would be almost invincible. With Superman - like powers, Naruto could fly around and keep an eye on all the hidden villages, preventing any surprise attacks. His super strength could be used to rebuild the village in no time after any destruction. Also, his x - ray vision could be used for various things like finding hidden traps or enemies. The power dynamic in the ninja world would shift completely, and Naruto would become an even greater legend.
