I'm not sure who Percy specifically is without reading the fanfiction. It could be an original character created by the author, or perhaps a reimagined version of a known character from a particular franchise that the fanfiction is based on.
It could be his quick thinking. Maybe in the fanfiction, Percy is always the first to come up with solutions to difficult problems.
Yes, in many fanfictions, Percy Jackson is often depicted as a genius. His quick thinking, battle strategies, and ability to adapt in the original Percy Jackson series can be enhanced even further in fanfiction. Writers might give him an even greater understanding of mythology, or make him a master at solving complex puzzles that he comes across in the fan - created adventures.
In fanfiction, his knowledge of different mythologies can be greatly expanded, making him seem like a genius. For instance, he could have an encyclopedic knowledge of not just Greek, but also Roman, Norse, and Egyptian mythologies, which helps him in unexpected ways during his adventures.
I don't know for sure as I haven't read this particular fanfiction, but usually in fanfiction, Percy could be a character from a popular book, movie or TV series.
I don't have enough information to know exactly who Percy is. He could be an amateur singer who loves fanfiction and decided to do this project.
There's also 'Female Percy: A New Heroine'. Here, Female Percy brings a fresh perspective to the story. Her fighting style is different, more fluid perhaps. And her relationships with the gods are also unique. Instead of the typical male bravado, she uses her wits and charm to get through tough situations.
Percy could be a fan of the original work that the fanfiction is based on. Maybe he's someone who has a deep understanding of the source material and thus is in a good position to break down the fanfiction.
I'm not sure as the statement doesn't provide much context. Percy could be a character unique to that particular fanfiction. It might be a character created by the fanfiction author with certain special traits since they are described as 'the oldest being' in this work.
In this fanfiction, Percy is a character who is the son of Erebus. But without more context from the specific fanfic, it's hard to say exactly who he is beyond this basic family relation. He could be a new take on a well - known Percy from other mythologies or stories, with different powers and a different role to play because of his parentage.
Percy in 'percy controls poison fanfiction' could be a character that the fanfiction author has designed with unique abilities related to controlling poison. Maybe it's someone inspired by a real - life figure, a historical character perhaps, but more likely it's a fictional creation within the realm of the fanfiction. It could also be that Percy is a character borrowed from a popular book, movie, or game series, and the fanfiction writer has given them this new role of controlling poison for the purposes of their story.
