The other gods who don't trust Hades might be antagonists. They could see Bella as a threat because of her relation to Hades. For example, Zeus might be worried that Bella could one day try to overthrow him or cause trouble in the order of the gods.
Perhaps there's a plotline where Bella discovers some hidden powers she has as Hades' daughter. She could then use these powers to either protect the underworld or cause chaos, depending on her motives. For example, she might be able to control the souls in the underworld in a unique way that no one else can. This newfound power could attract the attention of other powerful beings, leading to various adventures and challenges.
Well, one possibility could be that Bella discovers her true parentage as Hades' daughter gradually. Maybe she starts to show powers related to the underworld, like being able to communicate with the dead or having some control over shadows. This could put her in a difficult position in the normal world of Forks as she tries to hide these new abilities from her friends and family while also trying to understand her new identity.
She would likely become more confident. Knowing she is the daughter of Hades, a powerful god, would give her a sense of self - worth that she might not have had before. For example, instead of being the damsel in distress in her relationship with Edward, she could be an equal partner, using her powers to protect him and his family if needed.
One possible plotline could be Bella's struggle to fit in both the Underworld, her father Hades' realm, and the world above, which is more associated with her mother Persephone. She might face discrimination or misunderstanding from both sides, and the story could be about her journey to find her own place.
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.
Another option is Fanfiction.net. There are many writers who contribute their works there. However, the quality can vary. You may need to sift through some to find the really good ones about Bella, the daughter of Hades and Persephone. Look for ones with high ratings and a lot of reviews as they are usually more engaging.
I'm not sure as I haven't read that specific fanfiction. But generally in a fanfiction, Bella being the daughter of Trigntins would likely mean she has a special role within the story's universe created by the fanfic writer.
I recommend the novel, White Joy, to you. This was a modern romance novel about urban life. It told the story of the female protagonist, Bai Huanxin, who was adopted from birth. Although it was not explicitly mentioned that the female protagonist was adopted by Hades, this novel may meet your needs. I hope you like this recommendation!
Sure. In the world of fanfiction, the idea of Bella being Voldemort's daughter is not unheard of. Fanfiction writers like to take existing characters and create new backstories or relationships for them. This particular concept could lead to all sorts of interesting plot twists. For example, it could change the dynamics between Bella and other characters in the Harry Potter universe, and also how she interacts with Voldemort. Maybe she could be a secret weapon or a source of redemption for him, or perhaps she could be a force of chaos in her own right.
