There could also be other secondary characters. For instance, the boy's parents who hire the cockvore babysitter. They might be clueless about the true nature of the cockvore. And then there could be neighbors or friends of the boy who notice something strange about the babysitter, which could add some conflict or mystery to the story.
Maybe it's a story where the 'cockvore' is a misunderstood creature. The babysitter, who is this cockvore, is actually very gentle with the boy. They go on adventures in a fantasy world where the cockvore shows the boy how to survive in a strange land. It could be filled with elements of discovery and friendship between the two.
Obviously, the orphan boy is the central character. Additionally, there might be a strict but fair orphanage caretaker. And there could be a wealthy benefactor who takes an interest in the boy's future and tries to help him in different ways.
A pedophile should never be in a position to babysit or give a child a bath. This is extremely inappropriate and dangerous as pedophiles have abnormal and harmful sexual interests in children. Protecting children from any potential harm from such individuals is crucial.
There might be a wizard or a magical creature who causes the transformation. This character would play a significant role as they are the catalyst for the whole story. For instance, if it's a fairy, she might have her own motives for turning the boy into a bride, like teaching him a lesson about vanity or pride.
The main characters could be the country boy himself, of course. And a girl from the same small town, like the local baker's daughter or the farmer's niece. They might have known each other since childhood.
The main characters could be a high - school girl and boy. The girl might be a popular one who likes to bully the less popular boy.
The boy in the diaper and onesie would be the central figure. There could also be a pet in the story, like a dog or a cat, that is curious about the boy's diaper and onesie. The pet could be another important character, adding some fun and chaos to the story as it tries to play with the boy's diaper or chew on the onesie.
The main character would obviously be the teen boy himself. His parents could also be important characters. For instance, if he is gaining weight due to overeating, his parents might be concerned and try to help him with a healthier lifestyle. They could be the ones who encourage him to exercise or eat better.
The girl could be a young athlete and the boy could be her rival in a sports event. She has more determination and thus beats him.
Astro Boy would definitely be one of the main characters as the title implies. Another could be a human girl or another robot who becomes the object of his love.
