Well, perhaps the story could start with Percy feeling disillusioned with the traditional order. He might be drawn to the chaos because he sees the flaws in the existing system. Then, as a general of chaos, he could start to gather a group of misfits who also believe in change. They'd likely face opposition from the forces of order, leading to some epic battles and tense stand - offs.
His character would likely become more unpredictable. He'd start to break free from the conventional moral and ethical constraints he once had. This doesn't mean he'd become evil, but rather that he'd view things from a different perspective. For example, actions that were once considered wrong in the context of order, might seem necessary in the chaos he now commands.
Well, perhaps Percy starts off as an ordinary character but gets drawn into the chaos realm. He could be forced to become an assassin due to some threat to his friends or family. Maybe he discovers new powers that make him suitable for this role.
Well, he might gain incredible cosmic powers. He could have the ability to manipulate space, time, and matter at will. His appearance might change to something more otherworldly, with a glowing aura perhaps. And he could have a new level of wisdom, seeing the grand design of the universe.
Maybe the gods or powerful beings who are trying to maintain the current balance and see Percy's new role as a disruption. They would try to stop him from carrying out his assassinations in the chaos world.
In this fanfiction, Percy could gain his extraordinary power by facing and overcoming numerous challenges. Each battle he fights, every enemy he defeats, could leave him with a new ability or strength. It's possible that he has a unique connection to an ancient and powerful force, like an old primordial energy that he manages to tap into, which gradually makes him more powerful than Chaos.
Percy's character would evolve into a more solitary figure. As Chaos, he'd be in a realm where few can understand him. He might struggle with loneliness, yet at the same time, he'd be filled with a sense of purpose that is much grander than his previous quests. His loyalty would shift from his friends on Earth to the well - being of the entire universe.
In a fanfiction of Percy as the Father of Chaos, he could be in a constant struggle between maintaining order within the chaos he controls and letting the chaos run wild.

He could also have a special connection with certain elements in nature that are associated with chaos, like storms or wildfires.
