Yes, it can be quite popular. Many Naruto fans are intrigued by the idea of Naruto having such an extraordinary lineage as being the son of Kaguya Otsutsuki. It adds a whole new layer of depth and mystery to his character, allowing for different interpretations of his powers and his place in the Naruto universe.
The plot might involve Naruto learning about his heritage as Kaguya's son. This could lead to a whole new understanding of the ninja world for him. He might face discrimination from some who fear his power, while others see him as a potential savior. He could also have to unlock the secrets of Kaguya's power within himself to face a great threat.
Perhaps there could be some of Kaguya's old allies or servants who come back to serve Naruto. Or new villains who are related to Kaguya's past enemies.
His unique ninja skills for sure. Things like his taijutsu, which is his physical combat ability. In a world of demigods who mainly use swords and magic, Naruto's hand - to - hand combat style would be a fresh addition. Also, his chakra control could be seen as a different form of energy manipulation compared to the magic in the Percy Jackson world.
Well, if we consider the concept of gods in both universes. In Naruto, Kaguya was like a god - like being. In Percy Jackson, there are the Greek gods. There could be a plot where the Greek gods sense Naruto's power as the son of Kaguya and either try to recruit him or see him as a threat. This could lead to all sorts of adventures as Naruto tries to find his place in this new world full of demigods, monsters, and strange magic.
Well, in such a fanfiction, Naruto's status and abilities would be greatly influenced. His relationships with other characters might also undergo major shifts. The story could explore new conflicts and alliances based on this unique parentage.
One interesting plot twist could be that Naruto has hidden powers that are only awakened when he discovers his true heritage as Kaguya's son. These powers could be something completely different from what he already has, like the ability to control space - time in a unique way.
