The plot could involve her on a quest. Maybe she's searching for a way to break the cycle of Kronos' evil. She might team up with Percy Jackson and other characters. They could face various monsters and challenges along the way. And she could be constantly battling her own inner demons related to her father's nature, like a tendency towards power - hunger that she has to overcome.
The character development of Kronos is also important. Fanfic writers often explore his past and what led him to become the villain he is. They might give him more complex motives, like a desire for revenge that goes beyond just power. Also, the relationships between the characters, like Percy's relationship with his friends in the face of Kronos' threat, are key elements. In some fanfics, these relationships are tested and strengthened in different ways.
She could potentially have the power of regeneration. Kronos was a powerful being, and if she inherits some of that essence, she might be able to heal from wounds faster than normal demigods. This would make her a very tough opponent in combat as she could keep coming back even after taking serious hits.
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.
In a fanfic scenario where Percy Jackson joins Kronos, it could be a very interesting exploration of the 'what - ifs'. Percy has a strong sense of justice, so for him to side with Kronos, Kronos must have presented a very convincing argument. It could be that Kronos showed Percy a future where the demigods are constantly oppressed by the Olympians. However, this would also mean Percy has to go against his instincts and the relationships he has built. His friends like Annabeth would be in shock and try to bring him back to the right side. This could lead to some intense battles not only between the demigods and Kronos' forces but also within Percy himself as he struggles with his new allegiance.
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.
One interesting concept could be the exploration of Percy Jackson's relationship with Kronos in a fanfic. Maybe it delves into how Percy, as the'son of Kronos' in this fan - made story, grapples with his new identity and the powers that might come with it. It could also be about the moral dilemmas he faces, like whether to embrace the dark side associated with Kronos or fight against it.
It could be one of Kronos' old allies who feels betrayed that Percy is now in a position of power. Maybe someone who was promised a lot by Kronos but didn't get it.
