Well, it could be about a young fan who dreams of meeting Percy. Maybe the fan follows Percy's journey to the Olympics, writes him letters, and finally gets to meet him at an event. It could also involve the fan getting inspired by Percy to start swimming themselves and facing their own challenges in the pool.
Obviously, Percy would be one of the main characters. And then there could be the fan, who might be a young person, maybe a teenager named like, Sam or something. There could also be Percy's coach, who plays an important role in his training and success at the Olympics.
One possible storyline could be Percy using his water - related powers to his advantage in the Olympics. For example, he might be able to swim faster than normal humans because of his ability to control water currents. Another could be him facing challenges from other supernatural beings who are also competing in the Olympics, disguised as regular swimmers.
A possible biggest rival could be another demigod who has water - related powers but uses them in a more underhanded way. This rival might be jealous of Percy's natural talent and try to sabotage him during the races.
In the fanfiction world, 'Percy Jackson: A Swimmer's Destiny' is quite good. It starts with Percy being recognized for his extraordinary swimming talent in the mortal world. But as the story progresses, he realizes his swimming is linked to his demigod heritage. He has to compete in a series of swimming challenges that are not just about speed but also about using his demigod powers underwater. Another interesting one is 'Percy, the Olympic - level Swimmer'. Here, Percy aims to participate in the Olympics, but he has to deal with various mythological obstacles that try to stop him from achieving his dream, all while using his amazing swimming skills.
One idea could be to explore the relationship between Percy and Apollo in a modern setting. Maybe Percy has to team up with Apollo for a mission, and during the process, they learn from each other's strengths and weaknesses. Another idea is a story about Percy and Poseidon's father - son relationship within the context of the Olympian world, like Percy trying to prove himself to his father in a new way.
First, decide which Olympian god you want to focus on in relation to Percy. Then, think about the setting. It could be in the Camp Half - Blood, or in one of the Olympian realms. Next, come up with a basic plot like Percy needing the god's help for a quest or the god asking Percy for a favor.
Besides Percy, his agent could be a character. The agent would be responsible for handling Percy's endorsements, scheduling his competitions, and dealing with the business side of his athletic career. There could also be a physiotherapist, especially if Percy gets injured during his training or competition. This person would help him recover and get back to peak performance. Another possible character is a fan. A die - hard fan of Percy who follows his every move, collects his memorabilia, and is always there to cheer him on, either at the stadium or through social media. And there could be a local sponsor who is investing in Percy and hoping for his success at the Olympics.
One common theme is perseverance. Percy has to keep training hard and not give up in the face of tough competition. Another theme is self - discovery. As he becomes a famous swimmer, he learns more about himself and his capabilities. For example, he might discover that he has a greater tolerance for pain and stress than he thought. Also, friendship is often a theme. He could have friends who support him through his swimming journey, or he might make new friends in the swimming community.
One common theme is self - discovery. Percy often discovers new things about himself and his powers while swimming. Another theme is competition. He might compete against other swimmers or mythical beings in the water. Also, there's the theme of heroism. His swimming skills are often used to save others or complete heroic tasks.
