Another plotline could be Naruto's journey to the Shinto realm. There, he could learn about his parents' past, the history of the Shinto gods, and gain new powers that he then brings back to the ninja world to make it a better place.
Naruto's character might develop a new sense of responsibility. Since he is the son of Shinto gods, he may feel obligated to protect not only his village but also the world from threats related to the divine realm.
Well, it depends on the specific fanfiction. There are countless Naruto fanfictions out there, and while some might choose to elevate Naruto to the status of a Shinto god for the sake of an interesting plot or unique world - building, others may not go in that direction at all. It really varies from one writer's imagination to another.
The idea of Naruto being the son of Greek gods is really creative. His journey would be different. For example, he could have to go on quests like the heroes in Greek mythology. His friends in the ninja world might be confused by his new powers and the strange things that start to happen around him. It would be a story full of adventure, as he tries to balance his two heritages and save both the ninja world and maybe even parts of the Greek mythological world.
It could also have implications for the world - building in the fanfiction. Shinto beliefs have certain concepts about the cosmos and the afterlife. If Naruto is a Shinto god, these elements could be incorporated into the story's setting. Maybe there would be new realms or spiritual entities related to his divinity.
It's difficult to determine its popularity. While the idea of Naruto as a Shinto demigod sounds interesting, popularity in the world of fanfiction can be very subjective. Some people might be really drawn to this concept and it could be popular within a niche group of Naruto fans who are into Shinto mythology and the idea of Naruto having god - like powers. However, it might not have caught on with the wider Naruto fan community. There are many factors that can influence its popularity, such as the writing quality, how well - known the author is, and how often it is promoted within the fanfiction community.
One way is through a crossover of quests. For example, Percy could be sent on a quest that involves the Shinto gods' realm. Maybe he has to retrieve an important artifact that is sacred to the Shinto gods. This would bring his world of Greek demigods and the Shinto gods' domain together in an exciting adventure.
It could be about Naruto having god - like powers and being related to Shinto demigod concepts in a fan - created fictional story. Maybe it explores Naruto's new level of power that is on a divine scale within the framework of Shinto - inspired ideas.
A possible plot could be that Percy is summoned to Japan by the Shinto gods to help stop an ancient evil that is threatening both the Greek and Shinto worlds. This evil could be a powerful demon that has the ability to disrupt the balance between the two pantheons.
Maybe the gods are some of the tailed beasts in a more divine form. Since they are powerful entities, they could raise Naruto, teaching him how to better control the power of the Nine - Tails within him and also how to communicate with other tailed beasts on a more spiritual level.
