A great plotline could be Kronos corrupting some of Percy's friends, and Percy having to decide whether to fight them or try to save them first. This adds a moral and emotional conflict to the story. In many fanfictions, this kind of internal struggle makes the story more engaging. For example, Percy might be torn between using his sword on a friend turned enemy or trying to find a way to reverse the corruption.
One interesting plotline could be Percy having to deal with the conflict of being the son of Kronos while still being a hero. He might struggle with the dark legacy of Kronos within him. Another could be his relationship with Thalia evolving in unique ways, like they team up against a new and powerful enemy that threatens both their existences.
One interesting plotline could be a joint quest where Percy Jackson and the Romans have to team up against a common, extremely powerful enemy. For example, a primordial god that threatens to destroy both their worlds. This would force them to put aside their differences and use their unique skills and powers together.
Well, perhaps in the fanfiction, Percy is tortured by Kronos in a way that involves his demigod powers being slowly drained. This would make him feel weak and vulnerable, which is a huge contrast to his usual strong self. His torture could also be a way for Kronos to try and break his spirit so that he can turn Percy to his side. Meanwhile, the gods might be debating whether or not to interfere, adding another layer of conflict to the story.
Another plot might be a scenario where Percy tries to reason with Kronos. He could attempt to understand Kronos' motives for wanting to destroy the Olympians and find a compromise. This would be a complex and emotional journey as Percy has to face the being who nearly destroyed his world.
Obviously, Percy Jackson and Kronos are the main characters. Percy is the hero, the son of Poseidon, with his powers over water and his ability to lead. Kronos is the powerful Titan, the main antagonist, with his devious plans to take over the world.
One interesting plot could be Fem Kronos trying to manipulate Percy in a more complex way than in the original stories. Maybe she uses her charm as a female figure to deceive him into doing things that would benefit her ultimate goal of ruling. Another plot might involve Percy having to face his own inner demons when dealing with Fem Kronos, as she represents a different kind of threat compared to male Kronos. And there could be a plot where Fem Kronos teams up with some other minor gods or creatures who have grudges against the main Olympian gods, and Percy has to stop their combined forces.
Well, in a fanfiction, a plotline could be that Percy Jackson is on a quest and somehow crosses paths with Voldemort. Voldemort senses Percy's power and wants to study it. Percy, not knowing much about the wizarding world, initially mistakes Voldemort for just another monster. As they interact more, they realize that their worlds are more intertwined than they thought. Another plot could involve a powerful artifact that both of them are after. The artifact has the power to change the balance of both their worlds. So they are in a race against each other to get it, but along the way, they start to understand each other's motives and might even consider working together to keep the artifact out of the wrong hands.

His actions force the heroes to become stronger, both physically and mentally. For instance, his threat might make Percy Jackson more determined to master his powers. Also, Kronos can be used to introduce new plot elements, like a new weapon or a magical item that has the power to stop him.
