Well, in some fanfictions, a great plotline is Percy having to learn how to control his chaos powers. He could be accidentally causing chaos in the mortal world, like making natural disasters occur because his emotions are tied to his powers. Also, there could be a plot where Percy has to team up with some unlikely allies. Say, some minor gods who see potential in him as the heir of chaos to overthrow the more tyrannical major gods. This would lead to a whole new set of power dynamics and political intrigue within the world of Greek mythology.
A really cool plotline might be Percy's journey to find out the true origin of his inheritance as the heir of chaos. He could travel to long - forgotten places in the Underworld or on Mount Olympus that hold the secrets of his power. Along the way, he might encounter ancient prophecies that foretell his role not just in the world of the demigods, but in the entire cosmos. And his battles wouldn't just be physical; he could be in a mental tug - of - war with the very essence of chaos itself, trying to understand if he can use it for good or if it will ultimately consume him.
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.
Another plotline might involve Percy forming new alliances with other powerful beings in the chaos realm. He could be on a quest to gather ancient artifacts that are tied to the chaos powers, which would lead him to various mysterious and dangerous places. Along the way, he'd have to learn about the history and secrets of chaos, and how it all relates to his destiny as the heir. This would also involve a lot of character development as he struggles with the weight of his new role.
Another plotline could involve Percy's relationships with other characters. Maybe he has to face some of his old friends who now see him as a threat because of his association with chaos. Or perhaps he forms new alliances with characters who are also on the side of chaos, but they have different motives.
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.
Another plotline could involve Percy's relationship with other characters in the context of chaos.

One interesting plotline could be Percy's struggle to adapt to his new role as the adopted son of Chaos. He might have to deal with new powers that are both a blessing and a curse.
