I don't know for sure, but likely the main character is the baby sitter. There may also be the children they are taking care of as important characters.
Since it's a 'baby sitter graphic novel', the central character is no doubt the baby sitter. The children under their care would be main characters too. There could be a best friend of the baby sitter who gives advice or helps out sometimes. And don't forget the pets in the house if there are any. They could add some fun and chaos to the story, like a mischievous cat that always gets into trouble while the baby sitter is trying to keep the kids in line.
Kristy is one of the main characters. She's really organized and is sort of the leader of the baby - sitting club. Claudia is another main character. She's known for her unique style and love for art. Mary Anne is also important. She's more shy and reserved compared to some of the others.
The sitter is surely one of the main characters. There might be other characters like the parents of the baby dragons if they are still in the picture. There could also be a rival sitter or someone who doesn't believe in the way our main sitter is taking care of the baby dragons, which could create some conflict in the story.
I'm not sure specifically as I haven't read it. But generally, a graphic novel about a baby sitter might be about the daily adventures and challenges the baby sitter faces while taking care of kids. It could include things like dealing with naughty children, handling unexpected situations at the house, or building special bonds with the kids they look after.
Since there is limited knowledge about 'hell baby graphic novel', we can only guess the main characters. The titular hell baby is surely a key character. There may be some antagonists in the form of dark creatures native to the hellish setting. And there could be some side characters that help or hinder the baby's journey. For instance, there might be a wise old soul in this hellish place who gives the baby advice or a group of small imp - like creatures that are constantly causing trouble for the baby.
I don't know for sure. It could be a young child as the main character since it's about baby teeth.
Since it's part of the Baby - Sitters Club series, we can assume that the main characters are likely the regular members of the club. They are probably a group of young girls with different personalities. Some might be more responsible, while others could be more creative or fun - loving. They each bring something unique to the club and the babysitting jobs they take on. We may also see some recurring characters like the parents of the children they babysit or the children themselves who have developed relationships with the sitters over time.
The main characters are most likely the core members of the Baby Sitters Club. These could be girls who are responsible, love kids, and are good at handling babysitting tasks. They would each have their own personalities, some might be more outgoing and some more shy, but all united by their love for babysitting.
The main characters are probably the babysitters who are part of the club. They are likely to be the ones we've seen in previous installments, like Kristy, Claudia, and Stacey. They each have their own personalities. Kristy is often the leader type, Claudia is artsy, and Stacey is the fashionable one. In this 'Baby Sitters Club 9 Graphic Novel', they are probably still at the center of the story, taking on babysitting jobs and dealing with all the related situations.
We can only guess without reading the graphic novel. The baby is surely a key character. There could be a caregiver, perhaps a mother or a nanny, who has a complex relationship with the baby. And there might be an antagonist too, someone or something that is either threatened by the baby or is trying to use the baby for their own purposes because of its unique 'in black' characteristic.
I'm not sure exactly, but it's likely to feature the regular members of the Baby Sitters Club. They are probably a group of girls who are into babysitting.
