Well, one interesting plot could be the heir of Pontus having to deal with new and strange sea monsters that are loyal to Pontus. They might have unique powers and abilities that the heir has to figure out how to control or defeat. Another plot could involve a power struggle between the heir and other demigods who fear the power of Pontus. And sometimes, there are plots where the heir discovers long - lost secrets about Pontus' realm and has to protect them from falling into the wrong hands.
In certain fanfictions, the plot could revolve around the heir of Pontus being hunted by an ancient cult that wants to use their power for evil. The heir then has to go on the run, hiding among the normal humans and other demigods while trying to find a way to stop the cult. There might also be a plot where the heir discovers they have a special connection to an ancient prophecy related to the sea, and they are the key to either saving or destroying the world of the demigods.
The heir of Pontus is the central figure. They will have their own personality, goals, and struggles. Alongside them, if the fanfiction is set in the Percy Jackson universe, characters like Grover could make an appearance. Grover might be involved in guiding the heir in some way, or he could be a sidekick during their adventures. Also, there could be villains in the form of other powerful beings from the sea or those who want to take advantage of the heir's power. For example, a sea witch - type character who tries to manipulate the heir.
One idea could be Percy discovering new powers related to being the son of Pontus. For example, he might be able to control underwater currents in ways he couldn't before. Another plot could involve him having to face a new type of sea monster that is specifically drawn to his Pontus heritage. He could also go on a quest to find an ancient artifact related to Pontus that has the power to either save or destroy the underwater world.
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 interesting plot could be Percy struggling with his new - found identity as the heir of Voldemort while still maintaining his loyalty to his friends in the Percy Jackson universe. It would be a battle of his demigod nature against this dark inheritance.
One possible plotline could be Percy having to fight against other champions of different deities who see him as a threat. Another is that he has to find a way to combine his new role with his loyalty to his friends and the Olympians. For instance, he may be forced to make a choice between following Pontus' orders that might seem harsh to his friends or standing by his friends and risking the wrath of Pontus.
Often, you'll see plots where Percy discovers his Gryffindor heritage in a really unexpected way. Maybe he has a vision or finds an old artifact that links him to Gryffindor. Then there are plots where he forms new friendships at Hogwarts. Since he's used to being a demigod, his relationships with wizards and witches can be really different. He might also get involved in Hogwarts house rivalries in a unique way because of his Gryffindor connection. There are also plots where Percy has to use his water - related powers in the context of the Hogwarts magic, which can be really cool to read about.
One interesting plotline could be Percy having to deal with the Slytherin values while still holding onto his own heroic nature from the Percy Jackson series. Maybe he has to face prejudice from some Hogwarts students who are suspicious of a 'half - blood' being the heir.
One interesting plotline could be Percy discovering new powers related to his status as the heir of chaos. Maybe he can manipulate reality in unexpected ways, like creating temporary portals to different mythological realms. Another could be his relationships with other characters evolving. For example, his friendship with Annabeth might face new challenges as his new powers set him on a different path. He might also have to deal with new enemies who are after the power he holds as the heir of chaos.
One interesting plot could be Percy having to deal with new mythological threats while trying to balance his college studies. For example, a group of rogue satyrs causing chaos on campus.

One interesting plot could be Percy and his friends going on a quest in a new, unknown realm. Maybe a place that's not part of the regular Greek mythology but still related in some way.
