Well, Percy is obviously one of the main characters. Since it's about him growing up on Olympus. Annabeth might also be a major character as she has a close relationship with Percy. She could be visiting him on Olympus or they could be having some long - distance communication that affects the story.
One interesting plot point could be Percy's relationships with the various gods. Since he's growing up on Olympus, he'd have unique interactions with them. Maybe he becomes a sort of protege to a particular god, learning their special powers or skills.
Well, it could be about Percy learning all kinds of sea - related powers from Poseidon. Maybe Poseidon teaches him how to control the tides or communicate with sea creatures. For example, Percy might start off as a young boy who is a bit clumsy with his powers but as he grows up with Poseidon's guidance, he becomes really proficient.
Well, Percy is the central figure for sure. There might be a hunter named Thalia who could be a main character. Thalia has her own backstory and her presence could greatly influence Percy's experience in the Hunt. Additionally, some new characters created specifically for this fanfiction could also be main characters, ones that interact with Percy on a regular basis and help shape his journey as he grows up with the Hunt.
Well, perhaps it could involve Percy learning about her powers with Poseidon's guidance. She might face challenges specific to being female in a male - dominated demigod world while having Poseidon as a father figure to support her.
A group of bandits might be the main antagonists. They see Percy as someone they can easily rob or enslave since he is all alone. Percy would then have to use his skills to outwit them.
Well, one possibility is that Percy has to learn to fend for himself in a harsh world. Maybe he discovers unique powers within himself as he faces various challenges alone. For example, he could learn to hunt and build shelters all by himself, much like a survival story.
Well, for this type of fanfiction, the plot might start with Percy being separated from his usual allies very early on. He'd be forced to navigate the mortal world by himself. Since he's growing up alone, he may not have the same understanding of his Greek heritage as he does in the original series. This could lead to him making different choices when it comes to using his powers. For example, instead of using them to protect Camp Half - Blood, he might use them to simply survive in a world that seems to be constantly against him.
One possible plotline could be Percy's struggle to adapt to the Hunt's way of life. He might have to learn their combat styles and rules. Another could be his relationships with the members of the Hunt, forming deep friendships or facing rivalries.
Grover might also be an ally. His connection to nature could be useful in Percy's new role. For example, he could help Percy understand any nature - related aspects of Olympus or deal with nature spirits in the realm. Also, some of the more benevolent gods like Poseidon (Percy's father) and Athena (Annabeth's mother) might side with Percy, at least to some extent, as they have their own interests in seeing Percy succeed in maintaining order in Olympus.
