Well, it might be unique because it gives a different perspective on Percy. Instead of the usual portrayals, making him a clear - sighted mortal could lead to a whole new set of adventures and relationships. It could explore how he interacts with the world around him in a more grounded way.
I haven't come across that exact 'percy is a clear sighted mortal fanfiction' myself. However, you could join relevant fan communities on platforms like Reddit. There, fans often share and discuss their favorite fanfictions, and you might find what you're looking for.
Well, it's possible that such a fanfiction exists given the creativity of fanfiction authors. They like to experiment with different relationship dynamics. But considering the popularity and the nature of Annabeth and Percy's relationship in the source material, this would be quite a shocker. It could also attract a lot of criticism from fans who are attached to the original relationship, while others might be interested in seeing how such a different plot would unfold.
I don't think it's a highly popular fanfiction genre in general. Popularity in fanfiction often hinges on how closely it adheres to the elements that fans love about the original source material. In the case of Percy, many fans are attracted to his demigod status and the fantastical world he inhabits. However, that doesn't mean 'percy is born a mortal fanfiction' has no audience. There are always those who enjoy exploring different 'what - if' scenarios, but it's likely not as mainstream as other types of Percy - related fanfiction.
The settings are completely different. Percy Jackson is set in a world where Greek mythology exists in modern times. It has Camp Half - Blood and various mythological creatures and gods from Greek lore. Shirou fanfiction would be related to a different fictional universe. So, it's obvious they are not related.
The settings are different. Percy Jackson is set in a world where Greek mythology is real. Kryptonians are from a science - fiction world of Superman. So, they can't be related in terms of fanfiction.
The overall themes are disparate. Percy Jackson focuses on heroism within the context of Greek mythology, family, and growing up as a demigod. Bleach, where Ulqiorra comes from, is about Soul Reapers, Hollows, and the balance of the afterlife. There's no connection that would suggest Percy Jackson is a fanfiction of Ulqiorra.
The settings are different. Percy Jackson is set in a world that combines modern America with Greek mythology. Nero fanfiction would likely be centered around Nero and a different set of themes related to him. So, just from the basic setting, they are not related.
The themes are a major giveaway. Percy Jackson deals with themes like growing up as a demigod, facing the wrath of the gods, and going on epic quests. Sans' story in Undertale is about the underground world, battles, and the game's unique mechanics. And the writing styles are different too. Rick Riordan's style for Percy Jackson is more about adventure and discovery in a real - world - meets - mythological - world, while Undertale has its own distinct style for Sans' story.
Isolation can be a theme too. Percy might feel isolated in the mortal world as he no longer has the same connection to the demigod world. He may feel like an outsider. Additionally, the theme of self - discovery is present. As he experiences life as a mortal, he discovers new aspects of himself, like hidden talents or interests that were overshadowed by his demigod life.
