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.
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.
Well, at first, they might be cautious around each other. Percy is used to being the main hero, and the daughter of Zeus's sudden appearance could make him a bit jealous or at least wary. But as they face challenges together, they start to respect each other. Maybe she saves Percy from a difficult situation, and he realizes she's not just there to steal his thunder. Over time, they could become good friends, relying on each other's unique skills in battles against monsters.
First, give him a distinct personality trait from his past life that still lingers. For example, if he was a very patient and wise person in his past life, he might still have that calmness about him. Second, let his reincarnation affect his relationships. He might be a bit of an outcast among the half - bloods at first because he's different. Third, give him a goal related to his reincarnation. Maybe he wants to find out why he was reincarnated and who or what is behind it.
You can develop her character by exploring her backstory. Maybe she was sheltered as a child because of Maxie's status. This could have made her curious about the outside world. Or perhaps she witnessed some of her father's less - than - noble deeds when she was young and it had a profound impact on her. Her reaction to these past events can show her growth and development as a character. Also, consider her skills and abilities. Is she a talented trainer? Does she have a special ability to communicate with certain Pokémon? These aspects can add depth to her character.
One interesting plot idea could be her struggling with the stigma associated with being Hades' daughter. For example, other demigods might be scared or distrustful of her at first. Another could be her going on a quest related to the Underworld, like trying to stop some escaped souls from causing chaos on Earth. She could also have a special power related to the dead that she has to learn to control, such as being able to see the last moments of a dead person's life, which could be both a gift and a curse as she might see some really traumatic things.
First, decide on their godly parentage. This will determine their basic powers and abilities. For example, if their parent is Athena, they'll likely be intelligent and strategic. Then, think about their backstory. Were they raised by their mortal parent alone? Or did they have some contact with their godly parent? Also, consider their flaws. Maybe they're overconfident because of their powers or they have a fear of being rejected by the godly community.
Start by defining their connection to the Dark God. Are they a willing servant? Or are they forced into this relationship? This will shape their personality and actions.
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.
To develop the character, start with his backstory. Since he's the son of Kronos, he might have grown up in a very different environment compared to other demigods. Maybe he was hidden away by a minor god who felt sorry for him. His past experiences of being alone and shunned because of his father would shape his personality, making him a bit of a loner at first.
In a 'Percy Jackson and a OC love fanfiction', you could also use the element of sacrifice. Let's say the OC is in danger of being captured by a powerful enemy. Percy risks everything to save her. This act of selflessness makes the OC see Percy in a new light. On the other hand, the OC could also sacrifice something for Percy, like giving up a chance to go back to her old life in order to stay with him at Camp Half - Blood. These sacrifices deepen their connection and lead to a stronger, more loving relationship.
