I recommend the book, This Voice Is For You. The male protagonist of this novel was a person with a dependence disorder, and his occupation was a voice actor. At the beginning of the novel, there was a scene of him dubbing the God of Heaven. Moreover, this novel was also a modern romance and urban life novel. I hope you like this fairy's recommendation.

Peter Pettigrew is a very likely character to be involved in more acts of betrayal in fanfictions. Since he already betrayed James and Lily Potter in the original story, it's easy to imagine him continuing his traitorous ways. Another could be Draco Malfoy. In some fanfictions, he might be made to do more extreme acts of betrayal rather than just being a bully. He could be forced to betray his schoolmates in a more serious way for the sake of his family's safety.
In a 'jinx graphic novel', the main character could very well be Jinx. There might also be a mentor - like figure who tries to guide Jinx through the troubles related to the jinx. Additionally, there could be an antagonist, someone who either caused the jinx or wants to take advantage of Jinx's situation. There could also be other characters that Jinx meets along their journey, like other jinxed individuals or those with the power to break the jinx.
I'm not sure as I haven't read the novel. But typically, a novel will have characters who initiate the acts of service and those who are the recipients. Maybe there's a protagonist who is on a journey of self - growth through service.
I'm not sure specifically as I haven't read the novel. But typically, there could be a protagonist who is in a desperate situation, like a young person trying to make it in a tough city. There might also be an antagonist who either causes or exacerbates the desperate situations.
It's possible that there are a group of friends who are important characters. They could experience things together, and their relationships could be tested throughout the novel. There may also be a character representing authority, like a government official or a community leader, who has an impact on the lives of other characters.
There could also be other characters involved. For instance, some of the Flash's friends or allies from his usual superhero team might make an appearance. They could either be helping the Flash deal with Jinx or getting caught in the crossfire of their encounters. Additionally, Jinx might have her own group of followers or partners in crime that could add more depth to the story.
