No. Fanfiction involving sexual content is not appropriate, especially when it involves a character like Percy Jackson which is often aimed at a younger audience. Such content goes against the spirit of the original work which is mainly about adventure, friendship and heroism.
Another one is 'Self - Insert: A New Demigod in Persy Jackson's World'. It focuses on the self - inserted character's unique powers and how they are received by the other characters. It's a fun read as it shows the character trying to prove themselves among the already established heroes in the story.
It's not likely that the actual Olympus (in the context of the Percy Jackson series being a place of the gods) reads fanfiction. Fanfiction is a creation of the fans in our world, and there's no indication in the books that the gods or Olympus as an entity would engage with it.
One positive aspect is that it can expand on the world of Percy Jackson. For example, it could explore different relationships between the characters in a non - romantic or sexual way, like the friendships between Percy and his fellow demigods. It can also create new adventures for the characters, taking them to different parts of the mythological world that weren't explored in the original books.
Think about the plot. It could be a new quest that your self - insert character embarks on, either alone or with the other characters from the series. You can also explore relationships. Maybe your character has a crush on one of the demigods or has a rivalry with another. The key is to make your story engaging and true to the spirit of the Persy Jackson world.
One possible reason could be that Percy feels betrayed by the Olympians first. Maybe he discovers some dark secrets about them that make him lose faith. For example, if he finds out that they have been using demigods unfairly in their battles or politics.
If Olympus read Percy Jackson fanfiction, the gods might be either amused or offended. Some fanfictions might portray them in a way that they don't like, and they could potentially take revenge on the author (if they could reach our world). But on the other hand, they might find some of the creative interpretations quite funny.
A new and powerful Titan who has been hiding and gathering strength all this time. He could be jealous of the Olympians' power and wants to take over. Percy would have to figure out his weaknesses and stop him before he causes too much destruction.
Percy himself is always interesting. In fanfiction related to The Staff of Olympus, he might have new challenges and growth. Another is Annabeth. Her intelligence could be used in unique ways to figure out the mysteries of the staff. Grover can also be really cool as he might use his nature - related powers in unexpected ways in relation to the staff.
In fanfiction, if Percy Jackson takes over Olympus, he might bring a new order. He could reform the archaic rules of the gods. For example, he might ensure fairer treatment of demigods, like better training and protection. Also, he could change the power dynamics among the gods, making them more accountable for their actions.
