The pairing is appealing because it's a bit of a 'what - if' situation. Percy has this connection with Calypso that was cut short in the original story. Fanfics allow readers to explore what could have happened if they had more time together.
Yes, there are quite a few. You can start by looking on popular fanfic websites like Archive of Our Own (AO3). There, you can filter by the Percy x Calypso pairing and find a variety of stories, ranging from short, sweet one - shots to long, multi - chapter epics that explore their relationship in different ways.
One popular trope is the 'forbidden love' aspect. Since Percy has his own world and Calypso was trapped on her island, their relationship defies the odds. Another is the 'fish - out - of - water' trope for Percy when he's with Calypso on her island. He has to adapt to her way of life. Also, the 'redemption' trope can be seen in some stories where Calypso gets a chance at a new life through her relationship with Percy.
Some popular 'Percy Jackson' fanfics often explore alternate universes. For example, there are those that change the character's fates. One might have Percy becoming a teacher at Camp Half - Blood instead of going on quests. Another type could be about different pairings, like Percy and Annabeth having a completely different relationship dynamic, which attracts a lot of readers.
One popular 'Calypso loves Percy' fanfiction is 'Calypso's Hope'. It delves deep into Calypso's feelings for Percy, exploring their relationship in a new and exciting way. Another great one could be 'Calypso's Longing' which focuses on her unrequited love at first and how she tries to win Percy over. And 'Calypso's Dream' where she has dreams about their future together and then tries to make them a reality in the fanfiction world.
One popular theme is exploring different relationships among the characters. For example, the friendship between Percy and Grover might be delved into more deeply, showing their adventures before Percy knew he was a demigod. Another theme is creating new quests. Writers might send Percy and his friends on a journey to a different part of the mythological world that wasn't covered in the books.
There are many great 'Percy Jackson' fanfics that focus on adventure and friendship. For example, some fanfics explore new quests for Percy and his friends in different mythological settings. They might involve encounters with lesser - known gods or monsters, and how the group overcomes these challenges together, staying true to the spirit of the original series which is mainly about the bonds between the characters and their growth through heroic deeds.
Friendship is also a big theme. Many fanfics expand on the relationships between Percy, Annabeth, Grover, and the other characters, showing how their friendships grow and are tested. For example, there might be a fanfic where Percy has to choose between saving Annabeth or Grover in a dangerous situation, and how that affects their friendship. Another theme is the exploration of the demigod powers. Writers might create scenarios where Percy discovers new abilities of his water - controlling power, or where other demigods develop their powers in unexpected ways.
One popular 'Percy Jackson' Wattpad fanfic could be those that explore alternate universes where the characters have different powers or relationships. For example, a fanfic might show Percy with the ability to control time. Another type could be fanfics that focus on a romantic relationship between Percy and Annabeth that goes through unexpected challenges. There are also fanfics that introduce new characters to the 'Percy Jackson' world, adding new storylines and adventures.
I'm not sure there are many positive or 'popular' fanfics with such a concerning topic as 'drugged'. Fanfic should generally promote positive and healthy themes. However, I haven't specifically searched for this kind of Percy Jackson fanfic, and I don't recommend exploring fanfics that involve such inappropriate or harmful concepts.
