In some fanfiction, there could be a time - travel aspect. Maybe a demigod travels back in time to prevent Kronos from being awakened in the first place. This would involve a lot of research into the past, interacting with ancient gods and demigods, and trying to change the course of history.
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.
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.
One interesting plot could be Percy's internal struggle with his new identity as the child of Kronos. He might battle against the dark urges that come with his heritage while trying to stay true to his friends at Camp Half - Blood. Another plot could involve Percy facing off against the other demigods who see him as a threat due to his relation to Kronos.
A possible plot is that fem Percy is sent on a quest that is somehow related to Kronos. Along the way, she discovers secrets about Kronos' past that she can use to her advantage. She might also meet characters who knew Kronos before he became the big bad, and these characters help her in her fight against him. For example, she could find an ancient weapon that was once used against Kronos and learn how to wield it effectively.
In fanfiction, Kronos's role is not just limited to being a villain. Sometimes, he can be a catalyst for character development among the demigods. 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.
One great Kronos fanfiction could be about his backstory before he turned evil. Maybe it explores his relationship with the other Titans and what led him to start the war against the Olympians.
If Kronos were to win in a Percy Jackson fanfiction, it would be a cataclysmic event. Kronos represents the old, chaotic order. His victory would mean the collapse of the current pantheon - based system. The gods' domains would be up for grabs, leading to widespread conflict among the Titans and other powerful beings. Percy and his allies would have failed in their quest to protect the world. The very fabric of the Percy Jackson universe, with its themes of friendship, heroism, and the fight against tyranny, would be shredded. It would be a very different and much darker world than the one we see in the original series.
One idea could be Percy having to face Kronos in a dream realm where Kronos tries to manipulate his mind. Maybe Kronos shows Percy a false future where his friends turn against him to make Percy doubt his alliances.
Well, a cool plot could be that Percy, as the General of Kronos, discovers a hidden power within Kronos' forces that could either save or destroy the world. He then has to race against time to figure out how to control this power. Also, there could be a sub - plot where Percy is constantly in conflict with his old Percy Jackson values while leading this new role. Maybe he has to find a way to reconcile his past self with the General he has become.
One idea could be that Fem Percy has a unique connection to Kronos. Maybe she can see into his past and uses that knowledge to try and prevent his rise. For example, she discovers a long - forgotten weakness of his from his early days. Another plot could involve Fem Percy being tricked by Kronos into doing his bidding at first, but then realizing his true evil nature and turning against him. This could lead to an intense battle of wills between them.
One plot idea could be that the female Percy Jackson has a psychic connection with Kronos' past self. She starts seeing visions of his rise and fall in the Titanomachy. Another could be that Kronos, in some way, tries to use the female Percy as a tool to regain his power but she manages to turn the tables and uses his own schemes against him. Maybe she discovers a long - lost secret about Kronos that could either save or destroy the world of the demigods.
