The first novel in Percy Jackson's series was "The Pyramids of Mars."
There are several. Percy, for sure. His ability to control water and his quick - wittedness make him stand out. Annabeth Chase is also very engaging. Her knowledge of architecture and her leadership skills are impressive. Also, Luke Castellan is an interesting character. His fall from grace and his complex motives add a lot of drama to the series.
It could be Chaos, as Chaos is often considered the primordial state from which all else emerged in Greek mythology - inspired Percy Jackson lore. So in fanfiction, it would make sense for Chaos to be the first being.
It could be a dark demigod who is also seeking the power of the first god but for evil purposes. This demigod might be jealous of Percy's connection to the first god and tries to stop him at every turn.
It's likely that Percy Jackson himself is still a main character. Since it's related to the Percy Jackson world, he would probably play a significant role.
No. In the official Percy Jackson series, there is no such scene where Percy Jackson and Thalia Grace kiss.
No. In the official Percy Jackson series, Percy is the son of Poseidon. Fanfiction often takes creative liberties and creates alternate storylines, but these are not part of the original canon.
Well, the themes in the Percy Jackson series are quite diverse. Friendship is super important. Percy and his friends rely on each other all the time. Also, there's the exploration of power. As demigods, they have special powers and they need to learn how to control and use them properly. And of course, the theme of belonging. Percy struggles to find his place in the world of mortals and gods.
The main characters are Percy Jackson, a demigod son of Poseidon. Annabeth Chase, a smart and brave daughter of Athena, and Grover, Percy's satyr friend. There are also other important characters like Chiron, the centaur who trains the demigods.
