One common theme is the exploration of forbidden love. Since the world of Percy Jackson has its own set of rules and norms, a lesbian relationship between characters might be seen as going against the traditional ideas in that world. Another theme could be self - discovery, where a character realizes her true feelings for another female character and has to come to terms with her own identity.
One idea could be exploring Percy's life if he had a different godly parent. For example, if he was a son of Hades, how would his powers and his relationship with the other demigods change? Another idea is to write about a time - travel adventure for Percy and his friends, where they go back to the era of the first Olympians.
Annabeth is also a very popular choice. Her intelligence and her relationship with Percy are often explored in fanfics. Writers might create scenarios where she uses her smarts to solve complex problems or where her relationship with Percy is put to the test in new and interesting ways.
One idea could be Percy having to face a new and powerful monster that is a combination of different mythological creatures. For example, a chimera with the head of a hydra. This would create a unique and challenging battle for him.
One popular 'Percy Jackson and the Olympians' lesbian fanfiction might be those that focus on the relationship between female characters like Annabeth and Piper. However, it can be a bit hard to specifically recommend one as there are many out there. You can try searching on fanfiction - specific websites and look for ones with high ratings and positive reviews.
First, develop a strong voice for your narrator. If it's Percy himself, make sure his internal monologue is distinct and engaging. If it's an omniscient narrator, give them a personality that shines through in the storytelling. Second, create emotional depth. Let your characters experience a wide range of emotions. For example, when a character loses a loved one, don't just skim over the grief but really explore how it affects them and their actions. Finally, research the original mythology deeply. The more you know about Greek mythology, the more authentic and interesting your fanfiction will be. You can include little - known myths or details that will surprise and delight your readers.
One possible plot could be that the Assassins discover a hidden artifact that has ties to the Greek gods. Percy and his friends from Camp Half - Blood get involved because they sense the godly power in the artifact. They team up with the Assassins to protect the artifact from a common enemy, like a group of rogue demigods who want to use the artifact's power for evil. The Assassins' skills in stealth and combat combined with the demigods' powers would make for some exciting action scenes.
