Annabeth could be one. She's been Percy's close friend and has a strong connection with him. Also, Piper could be a part as she has her own charm and abilities. And maybe Thalia, with her fierce nature.
Yes, it is quite popular. Many fans enjoy exploring different relationship dynamics for Percy Jackson in fanfiction, and the 'harem' concept, where he has multiple romantic interests, offers a lot of creative possibilities for writers to play with different character interactions and storylines.
One great 'Percy Jackson Harem Fanfiction' is 'The Son of Poseidon's Harem'. It has an interesting plot where Percy has to navigate relationships with multiple characters in a unique way. The character development is quite engaging.
One common theme is friendship. Despite the harem aspect, the relationships often start as friendships. Another theme is adventure. Just like in the original Percy Jackson series, the fanfictions usually involve quests and battles.
Another good one could be 'Percy's Harem Adventure'. This story takes Percy on a journey where he has to deal with his harem while also facing challenges from the Percy Jackson world. It has some really cool character developments and plot twists that keep you hooked from start to finish.
In Percy Jackson fanfiction, the idea of a 'God of Sex Harem' is a rather strange and often inappropriate deviation from the original themes. The Percy Jackson series is mainly about Greek mythology, friendship, and heroism. Fanfictions should focus more on positive aspects like exploring new adventures for Percy and his friends within the framework of the mythology rather than creating such improper concepts.
Common themes include the exploration of different relationships. There could be a mix of romantic - ish (but not overly sexual) feelings among the characters in the harem. Another theme is the power dynamics. With Percy having his own powers and the other characters in the harem having theirs, how they interact and support or challenge each other in terms of power is often explored. Also, the theme of growth, not just for Percy but for all the characters in the harem as they experience new things together.
Annabeth could be a likely member as she has a deep connection with Percy already. Another could be Piper, given her charm - speaking abilities and her friendship with Percy. And maybe Hazel, with her unique powers and kind heart.
There's a fanfiction named 'The Percy Harem Chronicles'. This one delves deep into the relationships within Percy's harem. It not only focuses on the action and adventure aspects typical of the Percy Jackson universe but also on the emotional bonds between Percy and the girls in his harem. For example, there are parts where they have to deal with jealousy and insecurities, which makes it a more complex and engaging read.
One common theme is the exploration of relationships. Given it's a harem - based concept, there's a focus on how Percy interacts with the various characters associated with Artemis. It could be romantic relationships, friendships, or rivalries.
