One common theme is the power dynamic. Since Apollo is often depicted as 'dark' in these fanfictions, there's usually a complex power struggle between Fem Percy, who has her own strength, and Apollo. For example, Apollo might try to manipulate Fem Percy's powers for his own ends.
Another theme is the exploration of divinity and mortality. Fem Percy, being a mortal (or demigod) in most cases, and Apollo, a god, have very different outlooks on life, death, and the world in general. This can lead to some really interesting character development and conflict as they interact. For instance, Fem Percy might question Apollo's actions that seem callous from a mortal perspective, while Apollo might not understand Fem Percy's attachment to her mortal life and friends. It's a great way to delve into the differences between the two worlds in the Percy Jackson universe.
One common theme is the exploration of a unique relationship dynamic between the two characters. Since Percy is female in these fanfictions, it often involves a different kind of chemistry compared to the original male - female relationships in the source material.
Another theme might be the exploration of power dynamics. Apollo is a powerful god and Percy, even as a female version, has her own powers. How they navigate their relationship with their respective powers is often explored. For example, they may have to work together against some common enemy using their combined powers, which strengthens their bond and leads to a deeper relationship.
Another theme is the exploration of their personalities. Dark Apollo is usually depicted as having a more complex and perhaps morally ambiguous side compared to the traditional view of Apollo. Percy, on the other hand, is known for his loyalty and courage. In these fanfictions, how their different personalities interact and either clash or complement each other is often explored. It could be that Percy's goodness starts to influence Dark Apollo's darker tendencies, or vice versa.

One common theme is friendship. Since they are both from the demigod world, many fanfictions explore how they can form a strong bond despite their differences. For example, they might have different views on how to handle a certain situation, but through communication and understanding, they become good friends.
One common theme is mentorship. Apollo, being an older and more experienced god, often takes on the role of mentoring Percy in different aspects. Another theme is the exploration of different powers. Since Apollo has his unique set of powers and Percy has his, their interactions often involve exploring how these powers can work together or against each other.
The theme of sacrifice also appears. In some fanfictions, either Percy or Apollo has to sacrifice something, like a part of their power or a relationship with another character, in order to be with each other. This shows the depth of their love and the challenges they are willing to overcome for their relationship.
Love across different statuses is also a theme. They come from different 'ranks' in the mythological world, and the fanfictions often explore how they bridge that gap. For example, in some stories, Percy has to deal with the jealousy or disapproval of other demigods who might think he's getting special treatment because of his relationship with Apollo.
One common theme is mentorship. Apollo often takes on the role of a mentor to Percy, teaching him about different aspects like new powers or knowledge. For example, in many stories, Apollo teaches Percy about the arts which Percy is not very familiar with initially.
One common theme is the exploration of power dynamics. Since Percy and Apollo have different powers in the demigod realm, fanfictions often play with how they interact based on that. For example, Percy's control over water and Apollo's over the sun and prophecy.
