Obviously, Percy Jackson is one of the main characters. He is the demigod hero with his own set of powers and a strong sense of justice. And then there's Fem Kronos. She is a female version of the powerful Titan Kronos. Her character might have different motives and ways of operating compared to the male Kronos we know from the original myths. There could also be other characters like Annabeth, Percy's friend and strategic partner, who might play a role in the fanfiction, either helping Percy against Fem Kronos or getting caught in the middle of their conflict.
The main characters are Percy Jackson and Fem Kronos. Percy, with his Poseidon - given abilities like controlling water and his heroic nature, is central to the story. Fem Kronos, on the other hand, is likely to be a very powerful and devious character. She may have her own plans for the world of the gods and demigods. Additionally, Grover, Percy's satyr friend, could also be involved. He might sense the danger Fem Kronos poses early on and try to warn Percy, or he could be used by Fem Kronos in some way to get to Percy.
Luke could also be a prominent character. Since he has a complex relationship with Kronos in the original story, in fanfiction he could play a role in either helping or hindering fem Percy's efforts against Kronos. Nico di Angelo is another possibility. His powers over the dead could be useful in a fight against Kronos, and he might team up with fem Percy for that reason.
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.
The main character is surely Percy Jackson. But in this 'son of kronos percy jackson fanfic', new characters might be introduced that are related to Kronos' side of the story. However, the classic characters like Annabeth Chase are bound to be there too. She would be crucial in Percy's journey as she often is in the original stories. Grover Underwood, Percy's satyr friend, would also be a mainstay. His loyalty and friendship with Percy would be tested and explored in this new narrative where Percy has this unexpected connection to Kronos.
Percy is the central figure, no doubt. But also, there could be other characters like Grover. Grover would be in a difficult position as Percy's friend. He would want to support Percy but also be cautious because of Percy's connection to Kronos. Additionally, some new characters might be introduced, perhaps other children of Kronos or characters from Kronos' past who have a role to play in Percy's story.
Obviously, Percy Jackson is one of the main characters. He is the central figure around whom the idea of 'betrayal' revolves. The son of Kronos is also a key character, as the one who feels betrayed by Percy. Other common characters might include Annabeth, Percy's girlfriend. She could be involved in either trying to clear Percy's name or getting caught in the middle of the conflict between Percy and the son of Kronos.
Kronos is also a popular character. His menacing presence and his complex backstory attract a lot of writers. Writers like to explore his motives for rebelling against the Olympians and what made him turn into such a villain.
The other Titans could be main antagonists. For example, Hyperion who is known for his great strength and his desire for destruction. He might not fully trust Percy and constantly try to undermine him in Kronos' eyes. Another could be Atlas, who is already a major foe in the Percy Jackson series. He might see Percy as a threat to his own plans within Kronos' regime.
The main characters are Percy and Fem Hades. Percy is the protagonist from the original series, and in the fanfiction, his story continues with his interactions with Fem Hades. Fem Hades, on the other hand, is a unique take on the Hades character. She could have different personality traits compared to the male Hades in the original mythology. There might be other characters that are introduced as the story progresses, but these two are the foundation of most Percy Jackson and Fem Hades fanfiction.
Maybe there are some original characters created by the fanfiction author. These characters could have their own unique abilities and backstories. They might be the ones who tip the scales in Percy's favor, for instance, by having a special power that weakens Kronos just before Percy makes the final blow.
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.
