Hades' character could be developed by showing his more paternal side towards Percy. He might start as a cold and distant figure but gradually show concern and protectiveness. For example, he could save Percy from a dangerous monster in the Underworld.
Hades' character development in a Percy Jackson Daddy Hades fanfiction could be really interesting. At first, he may be portrayed as the typical brooding and feared god of the Underworld. But as the story progresses, his relationship with Percy could force him to confront his own past traumas. Maybe he had a son or someone he cared about deeply in the past who was lost, and Percy's presence makes him relive those feelings. This could lead to him becoming more empathetic, not just towards Percy but also towards other mortals and demigods. He could also become more open to change in the Underworld, like trying to reform some of the harsher rules, all because of his connection with Percy.
You can start by giving her a distinct personality. Maybe she's shy because she's always been feared for her father's sake. Then, gradually show her growing confidence as she discovers her own strengths. For example, if she has the power to raise small skeletons as minions, at first she's scared of it, but later she learns to use it for good. Also, explore her relationships with other characters. Her friendship with Percy could be based on mutual understanding of being different among the demigods.
Some interesting plot ideas for Percy Jackson and Daddy Hades fanfiction could start with Percy accidentally ending up in a part of the Underworld that only Hades can access. Hades then has to guide him out, and during this journey, they start to understand each other better. Another idea is that there's a power struggle in the Underworld and Percy gets caught in the middle. Hades has to decide whether to protect Percy or use him for his own gain. Also, what if Percy discovers that Hades has a soft spot for him because he reminds him of someone from his past?
In fanfiction, Percy Jackson as the champion of Hades could bring a whole new dynamic. He might have to deal with the darker aspects of the Underworld. For example, he could be in charge of ensuring the souls are properly sorted, which is a huge responsibility.
His character would likely become more brooding. Being in the presence of Hades, who has a rather dark and serious nature, Percy might pick up some of those traits. He could be more introspective and less impulsive compared to when he was under Poseidon's influence.
One way to develop the storyline could be to explore Percy's struggle with his new identity. Since Hades and Persephone are such complex deities, Percy might have a darker side to him. He could struggle with controlling powers related to the Underworld, like shadow manipulation or communicating with the dead. For example, in a school setting, he might accidentally let out some spooky manifestations when he's stressed.
He'd probably be more brooding. Growing up with Hades, he'd be exposed to the darker side of the mythological world constantly. So, instead of the somewhat upbeat Percy we know, he might be more withdrawn and moody.
To develop her character, start with her appearance. Maybe she has dark, almost black hair like the shadows of the Underworld and pale skin. For her personality, she could be a bit of an outcast among the other demigods due to her father. This might make her a bit brooding but also determined to prove herself. Give her some quirks, like she always wears a small charm that was a gift from Hades.
In a fanfiction, Percy as the son of Zeus and Hades could have a very conflicted personality. He would be torn between the light and airy nature of Zeus's domain and the dark and brooding nature of Hades's. This internal struggle could be a major part of his character arc, as he tries to find a balance between the two aspects of his heritage.
In a fanfiction where Percy is the son of Hades and Poseidon, his powers would be truly extraordinary. He could have the ability to create portals in water that lead to the Underworld. This would give him an advantage in both battle and travel. His hydrokinesis could be tainted with the essence of death, so when he attacks with water, it could cause a draining effect on his opponents, sapping their life force. Additionally, he might be able to sense the presence of the dead in any water source, which could be used for both reconnaissance and protection.
Well, one way to re - imagine their relationship is to make it more of a partnership. In the original myths, Persephone is often seen as a victim of Hades' abduction. But in fanfiction, we could see them as two powerful deities who came together by choice. They could be equal partners in ruling the Underworld, with Hades respecting Persephone's opinions and decisions more.
