Annabeth could potentially be a yandere in some fanfictions. Since she already has a strong connection with Percy in the original series, some fanfic writers might take that to an extreme, making her overly possessive. Another could be a new, made - up character. Maybe a demigod who has been watching Percy from afar and then develops an unhealthy obsession.
One interesting plotline could be a yandere character becoming overly possessive of Percy. For example, they might try to isolate him from his friends at Camp Half - Blood, seeing them as threats to their 'relationship' with Percy. Another could be a yandere secretly sabotaging Percy's quests out of the fear of losing him. They think that if he doesn't go on these dangerous quests, he'll be safe and stay with them.
In this fanfiction, the 'yandere' aspect of Artemis likely adds a dark and obsessive twist to her relationship with Percy. Yandere characters are often extremely possessive. Artemis, being a goddess in the Percy Jackson universe, already has a complex character. Her being yandere towards Percy could mean she'd go to extreme lengths to keep him for herself. It might lead to her clashing with other characters who are close to Percy. This could also bring out new sides of Percy as he deals with such intense and perhaps dangerous affection.
One common theme is obsession. The Yandere character is usually obsessed with Percy. Another theme is possessiveness. The Yandere wants to keep Percy all to themselves. Also, there can be a theme of conflict, as Percy's normal life and relationships are disrupted by the Yandere's extreme behavior.
In Percy Jackson fanfiction, families can be depicted in various ways. Some might show Percy's family having new and unexpected adventures together. For example, his mom could discover a new magical ability that she uses to protect the family from an ancient threat. Another idea could be that Percy's half - brother Tyson becomes a key figure in protecting the family from monsters that target them specifically because of Percy's fame among the demigods.
One idea for a Percy Jackson famous singer fanfiction could be that a famous singer is actually a demigod in disguise. Maybe they use their music as a form of magic or to communicate with other demigods secretly. For example, their lyrics could hold hidden messages about upcoming quests or threats to the demigod community.
In such fanfiction, Percy often starts as a somewhat normal character. But as the story progresses, his yandere traits begin to surface. His love for the members of his harem becomes all - consuming. For example, he might start to isolate them from others to keep them to himself.
Well, in some fanfictions, it might be related to his demigod powers. Since he has a connection to the water element, blood being a liquid could potentially be manipulated in a way similar to how he controls water. Maybe he can sense the water content in blood and use his will to move or influence it.
