The main character is of course the sunlight girl. In addition, there might be a mentor - like figure who helps her understand and control her connection to the sunlight. There could also be a love interest, a character who is drawn to her because of her unique and positive qualities. And perhaps there are some side characters who are part of the community she lives in and are affected by her actions.
Since it's named 'the sunlight girl fanfiction', the girl herself is bound to be a main character. There could also be other characters like her friends or family members who support her or are part of her journey. Maybe there's an antagonist as well, someone who is opposed to her because of her sunlight - like qualities, perhaps someone representing darkness or jealousy.
A jealous witch could be the main antagonist. She sees the Sunlight Girl's popularity and power, and out of envy, she tries to cast dark spells on the girl to dim her light.
I'm not sure exactly who the main characters are without reading the book. But they are probably women who are the focus of the story.
There could also be other characters like Zeus, who might play a role in the story as he is the king of the gods. He could be involved in the situation regarding the stolen sunlight, either trying to find out who did it or having some other motives related to it. Demeter, Persephone's mother, could also be a significant character as she would be concerned about her daughter and the state of the world due to the missing sunlight.
I'm not sure specifically as I haven't read it. It could be about a girl who is associated with sunlight in some way, perhaps she has a sunny personality or some special powers related to sunlight.
I'm not entirely sure as I haven't read it in detail, but typically in dystopian novels, there's often a protagonist who is a bit of an outsider. Maybe there's a character like that in these novels, someone who starts to question the status quo of the dystopian world.
Without having read the 'bastards girl fanfiction', we can only guess. The main character is likely the girl who is identified as a 'bastard'. She may be accompanied by a cast of other characters. There could be a group of outcasts like her who form a kind of surrogate family. There might also be antagonists, perhaps those who uphold the social norms that marginalize her. And then there could be characters who are initially indifferent to her but later become important in her journey, like a kind - hearted noble who starts to see her worth beyond her 'bastard' status.
