In these types of fanfiction, a recurring plot element could be Percy using his knowledge of Artemis's weaknesses to his advantage. Since he was once on the side of good and knew a lot about her, as an 'evil' character, he could exploit this. There might also be a race or a quest involved, where Percy is trying to achieve some dark goal and Artemis is trying to stop him. The stories may also play with the idea of Percy changing the balance of power in the world of Greek mythology, and Artemis being one of the few who can oppose him.
One common plot element could be Percy being corrupted by some dark force and then opposing Artemis. Maybe he's under the influence of a powerful and malevolent god or a dark magic. Another element might be a power struggle between them, with Percy trying to undermine Artemis's authority or steal her powers.
Another plot element could be the conflict that arises from their relationship. Since Artemis is a virgin goddess in Greek mythology, her seducing Percy would go against her traditional image. This could create internal conflict within Artemis herself, as well as external conflict from other gods or goddesses who might oppose such a relationship. There could also be a struggle for Percy to understand and accept this new - found relationship with a goddess, considering his own mortal - turned - demigod nature.
One common plot element is the initial shock and confusion. Since Artemis is a virgin goddess in Greek mythology, the idea of her getting pregnant is quite out of the ordinary. So, in these fanfictions, there's often a lot of internal turmoil for both Percy and Artemis as they come to terms with the situation. For Percy, it might be about dealing with the implications of having a relationship with a goddess in such a way, and for Artemis, it could be about how this goes against her very nature.
One common plot element is Percy facing some sort of powerful enemy or threat that has captured Artemis. This could be a new, never - before - seen monster in the Percy Jackson universe.
I'm not sure about specific 'evil Percy and Artemis fanfiction' off the top of my head. But you can try searching on fanfiction websites like Archive of Our Own. They usually have a wide variety of fan - created stories with different themes, and you might be able to find some that involve this concept there.
One common theme is the idea of an unlikely partnership. Since Artemis is a maiden goddess and Percy is a male hero, their coming together for a common cause is often explored. For example, they might have to join forces to defeat a powerful enemy that neither could handle alone.
One common theme is the idea of an unexpected alliance. Since they come from different backgrounds in the original stories, seeing them work together is a popular concept.
Another theme could be mentorship. Artemis, being an ancient goddess, can be depicted as a mentor to fem Percy. She could teach Percy about her powers, the ways of the gods, and how to navigate the world of mythology. This can lead to interesting character development for Percy.
A frequently seen theme is the exploration of destiny. Fans often write about how Percy and Artemis are fated to be together despite all odds. It's like their souls are intertwined in a way that can't be broken. Also, the theme of sacrifice comes up. Sometimes, one of them has to sacrifice something important, like a part of their power or their reputation, for the sake of their relationship.
In some fanfictions, Artemis may hurt Percy because of her strict sense of justice. Say Percy breaks one of her rules unknowingly, like entering a sacred forest she has marked off. Artemis, being the goddess of the hunt and protector of the wild, might feel the need to punish him. This could lead to Percy getting physically injured, like being struck by one of her arrows. Or maybe Artemis is under a curse that makes her act out of character and she ends up hurting Percy without really meaning to. This then sets off a chain of events in the fanfiction where Percy has to deal with the injury and also try to find a way to break the curse on Artemis.
One common theme could be adventure. Given Percy's nature, the honeymoon might not be a typical relaxing getaway but rather an adventure - filled journey. Another theme might be discovery, as they discover more about each other on a deeper level.
