I'm not sure specifically as there can be many different fanfictions with this title. But generally, it might involve Percy Jackson in some new adventures related to chaos. Maybe he has to face new threats or make alliances in a world where chaos is a major factor.
The main character is Percy Jackson for sure. However, depending on the creativity of the fanfiction writer, there could be a whole host of other characters. We might see some ancient beings from the very origins of chaos. There could be other demigods from different cabins at Camp Half - Blood that we haven't seen much of in the original series but play important roles here. And don't forget about the villains. There could be new antagonists who are trying to either take advantage of the chaos or stop Percy from fulfilling his role as the champion of chaos. Annabeth would most likely be there to provide her intelligence and strategic thinking to Percy's more impulsive nature.
In some fanfiction, Percy Jackson might be depicted as a champion of Kronos, but this goes against his character in the original series. In Rick Riordan's official books, Percy is a hero who stands against Kronos and his evil plans.
In Percy Jackson fanfiction, the 'Champion of the Sun' could be a character with special powers related to the sun. It might be someone who has the ability to control sunlight, perhaps for combat or to perform other extraordinary feats. Maybe they are a hero figure within the fan - created story, with a backstory that ties them to the sun in some way, like being blessed by a sun - related deity.
The allure lies in the fact that Percy already has a very interesting backstory. As the Champion of Poseidon, fanfiction writers can expand on his powers and his place in the mythological world. For instance, he could be sent on quests that are specifically related to Poseidon's domain, like protecting a sacred sea temple from an ancient evil.
Another aspect could be Percy building his own team in the chaos realm. He would have to choose members who can adapt to the unpredictable nature of chaos. This could include demigods with unique abilities and even some minor gods who are disillusioned with Olympus.
In some fanfictions, Percy Jackson might be depicted as the God of Chaos, but this is not part of the official canon. Fanfiction writers often take creative liberties to explore different storylines and character developments.
The 'Percy Jackson Champion of the Pit Fanfiction' may center around Percy's growth as a character in this specific setting. It could be that he is chosen as the champion for a particular reason, like his special abilities or his courage. The story could then delve into how he uses his skills, such as his water - related powers, in the Pit. There might be a complex plot where he has to solve puzzles or complete quests within the Pit, all while facing opposition from both known and unknown enemies. And it's all part of the fan - made world that expands on the original Percy Jackson stories.
It might be a mortal who has been given special powers by the gods for a specific purpose. This mortal could be an unlikely hero, but through a series of events, they are chosen to be the 'Champion of the Sun'. They would then have to learn to control their new - found sun - related abilities and face the challenges that come with the title.
It could be a powerful demigod who has been corrupted by power. This demigod wants to be the sole champion of the arena and will stop at nothing to defeat Percy.
