In addition to the vampire and his pet, there could be a character who is trying to steal the pet from the vampire. This character might have some evil intentions, like using the pet for some dark magic or experiment. So these three types of characters - the vampire, the pet, and the one who wants to steal the pet - could be the main focus of the story.
The main characters could also include other vampires who might not be too happy about the vampire having a pet. They could see it as a weakness or something against their vampire code. There might also be some characters who are friends or allies of the vampire - pet duo, like a wizard who helps them out when they're in trouble.
I'm not sure exactly as I haven't read the specific 'Adopted by Vampires' novel. But typically, the adopted character would be a main character. There would also likely be the vampires who adopt this character, perhaps an older, more powerful vampire who acts as a sort of mentor or parental figure in the vampire family.
I'm not sure specifically as there could be many different characters in such a novel. It could have a vampire protagonist who is trying to navigate the world in Chicagoland while dealing with his or her vampiric nature.
I'm not sure as I haven't read it. But it could have a brave space captain as one of the main characters who has to deal with the vampire threat.
I'm not sure exactly who the main characters are without reading the novel, but it could be a vampire hunter who is on a quest to deal with these chicken legged vampires.
Perhaps there is a human character who befriends the vampires. They could be a key figure in helping the vampires adapt to modern human society or vice versa. They might also be the love interest of one of the vampires.
One of the main characters is Louis Creed. He's a doctor who moves his family to a new place near the pet sematary. His wife, Rachel, is also an important character. And there's Jud Crandall, an old neighbor who knows the secrets of the pet sematary.
I don't know for sure. It could be a young protagonist who loves pets and wants to become the best in the pet - related world.
Often, there's a strong and brooding male vampire as one of the main characters. He might be an ancient vampire with a tragic past.
I'm not sure specifically, but it could be some powerful vampires in Chicagoland and perhaps some humans who are important to the story.
I don't know as I haven't read it, but usually in vampire novels, there could be a vampire leader as a main character, perhaps a human who gets caught up in their world too.
