The exploration of different mythologies is also a theme. Castiel is associated with Christian angel mythology, while Percy is part of Greek mythology. Fanfiction might delve into how these two mythologies interact or clash when the two characters meet. It could be about how they view each other's deities or how the rules of their respective mythologies affect their relationship.
The theme of sacrifice is also quite common. Sally has already made sacrifices for Percy in the original series, and in fanfiction, this can be exaggerated or explored further. It could be something as simple as sacrificing her own comfort for Percy's well - being, or more extreme sacrifices in the face of greater threats. Additionally, the theme of Percy understanding Sally's sacrifices and how it affects his view of her as a mother and a person is also often explored in these fanfictions.
A lot of fanfictions also focus on the relationship between the two in a more emotional sense. Maybe Percy is lost and in need of guidance, and Rhea steps in as a mother - like figure. Or perhaps there's a more romantic undertone, which is a bit of a stretch given their different natures but makes for interesting stories.
The theme of family also comes up. Percy has a complex family situation, and Hestia can be seen as a mother figure in some fanfictions. This relationship can explore what it means to have a stable and loving family member in the chaotic world of Percy Jackson. It can also show how Percy responds to this new kind of family connection, perhaps growing and maturing as a result of Hestia's influence.
One common theme is friendship. Given the complex relationships between Percy, Nico, and Jason in the original series, fanfictions often explore how their friendship could develop further. They might go on adventures together that strengthen their bond.
One common theme is self - discovery. The OC often has to figure out their place in the Percy Jackson world, whether it's about their powers or their role in the grand scheme of things. Another theme is friendship. As the OC and Percy interact, they form a bond that is often tested but grows stronger over time.
One common theme is the clash of two different worlds. Percy is from the world of demigods and Persephone from the more traditional Greek mythological realm of the gods. Their relationship often explores how these two worlds can coexist or conflict.
One common theme is the clash of different power systems. Percy has his demigod powers like controlling water and his enhanced physical abilities, while the Witchers have their potions, signs, and sword skills. So, in these fanfictions, there's often a comparison or a combination of these powers. For example, how would Percy's ability to heal in water compare to a Witcher's use of a healing potion? Another theme is the exploration of different worlds. Percy comes from a world filled with Greek gods and modern - day settings, and the Witcher is in a medieval - like, monster - filled world. Fanfic authors often explore how Percy would adapt to this new and harsher environment.
One common theme is the battle of good vs. evil. Since Percy represents the good side and Kronos is a major villain in the series, many fanfictions focus on their clashes. Another theme could be the power struggle. Kronos is extremely powerful, and Percy has his own set of powers, so how they measure up against each other is often explored. Also, the idea of fate or destiny can be a theme, like whether Percy is fated to defeat Kronos once and for all.
One common theme is the exploration of their relationship against the backdrop of the Percy Jackson universe. It often involves them facing mythological creatures together.
One major theme is the struggle between different generations of mythological beings. Percy is a more modern hero, while Nyx is from the very beginning of Greek mythology. Their relationship can be seen as a symbol of how the new and the old interact. Additionally, the theme of transformation is often present. Percy might be transformed by his encounter with Nyx, either in terms of his powers or his understanding of the world. And of course, the theme of the night and its secrets, since Nyx is the goddess of the night, is also quite common in such fanfictions.
