In fanfiction, Percy Jackson as the champion of Hades could bring a whole new dynamic. He might have to deal with the darker aspects of the Underworld. For example, he could be in charge of ensuring the souls are properly sorted, which is a huge responsibility.
Maybe Percy discovers that there is a conspiracy within the Underworld to overthrow Hades. As the champion, he has to uncover the truth and stop the plot. Along the way, he meets old enemies who now see him as an ally of Hades and try to take advantage of the situation.
Well, it could involve Percy going on a quest specifically for Hades. Maybe he has to retrieve something from the Underworld that only he can do as the so - called 'Champion of Hades'.
Some of the more powerful and vengeful spirits in the Underworld itself could be antagonists. They might not want an outsider like Percy to be the Champion of Hades. They could try to undermine him at every turn, like spreading false rumors about him among the other Underworld denizens or directly attacking him when he's vulnerable during his quests in the Underworld.
Well, in fanfiction, if Percy is the Champion of Pontus, his story would be filled with more mystery. Pontus is an ancient and powerful entity. Percy might be called upon to do things that go against the traditional ways of the Olympian - influenced world he's used to. He could discover secrets about the origin of the sea and his own powers that were previously unknown. This would not only make for an exciting read but also show how Percy can adapt and make his own path even when given a very different role.
One possible fanfiction could be about Percy Jackson seeking the guidance of Hestia, the goddess of the hearth, who has now become a champion in some way. Maybe she is a champion against a new threat to the demigod world. Percy could learn new skills or gain unique powers from her. For example, powers related to home and family, which could be used to protect Camp Half - Blood in a different way than before.
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.
One common theme is the exploration of Hades' character. Many fanfictions try to humanize him, showing that he's not just the 'bad guy' as he's often portrayed in the original stories. For example, they might show his love for his family in a different way.
