Naruto could use his chakra control to enhance his Kryptonian super speed. For instance, he could focus chakra on his legs while using his Kryptonian speed to move even faster and more stealthily. Also, his shadow clone jutsu could be combined with his Kryptonian powers. He could send clones with super strength or heat vision to attack enemies from different directions.
One popular kryptonian fanfiction might be those that explore the backstory of Superman on Krypton before it was destroyed. For example, stories about his family's life and status on the planet.
Well, it could be really interesting. Naruto, with his ninja skills, suddenly having Kryptonian powers like super strength and flight would change the Naruto universe completely. He might be able to defeat his enemies even more easily or use his new powers in unique ways in battles against the Akatsuki. For example, instead of just using Rasengan, he could punch with Kryptonian strength while using chakra to enhance the impact further.
In a 'Naruto is Kryptonian' fanfiction, there are numerous possibilities. Naruto could have all the typical Kryptonian powers such as super strength, invulnerability, and super speed. This would completely change the power dynamics in the Naruto universe. For example, in battles, he wouldn't need to rely on shadow clones as much. His heat vision could be a substitute for some long - range attacks. Also, his origin story would be different. Instead of being an orphan because of the Nine - Tails attack, he could be an orphan because of Krypton's destruction. His relationships with other characters would also shift. His friends might be in awe of his new powers, and some might be jealous or even afraid. And the villains in the Naruto world would have to face a much more powerful opponent. There could be a whole new set of storylines revolving around Naruto's discovery of his Kryptonian heritage and how he uses it to shape the ninja world.
A common theme is power enhancement. Since Kryptonians have superpowers, when combined with Naruto's abilities, it creates a new level of power. Another theme could be cultural clash, as the Kryptonian and Naruto cultures are very different.
First, do your research on Kryptonian lore. Know their powers, culture, and history. Then, create an original character with unique traits within that framework. For example, your OC could have a different take on their Kryptonian powers. Next, think about how this character will interact with the Supergirl universe. Maybe they become an ally or a rival.
The story of Zod and the Kryptonian heritage is an epic one. Zod was born into a noble Kryptonian family. His upbringing instilled in him a sense of pride and duty towards his race. When Krypton faced its impending doom, Zod had a different plan than others. He believed that Kryptonians should be the dominant force in the universe. So, he set out on his own path. Along the way, he met other Kryptonians who had also survived the destruction. Together, they formed a small group. They traveled from planet to planet, spreading their Kryptonian culture and technology, while also facing opposition from some civilizations who feared their power. But Zod was not one to back down easily, and he continued to fight for what he believed was the rightful place of the Kryptonians in the cosmos.
One of the common themes is adaptation. A kryptonian in a new fictional world, say like the Star Trek universe, has to adapt to new technologies, cultures, and rules. They can't just rely on their Kryptonian powers all the time. Also, friendship and alliances are often themes. In a crossover with the Harry Potter world, a kryptonian might form alliances with the Hogwarts students to fight a common enemy. And of course, discovery is a theme too. Discovering new things about the crossed - over world and also about themselves as a kryptonian in a different context.
First, do some research on Kryptonian lore from the official Superman comics or movies. Know about the planet, its technology, and the abilities of Kryptonians. Then, think of an interesting concept like a new Kryptonian character or a different take on a well - known event.
In this fanfic, there could be a scenario where Batman is exposed to Kryptonian technology that gives him some Kryptonian - like abilities temporarily. A Kryptonian comes to Earth to study this anomaly. They start off as adversaries but as they learn more about each other, they find that they can work together to protect Earth from a greater threat that only their combined skills can defeat.
