Well, different stories in the collection have their own sets of main characters. However, in general, there are often humans who are in various interactions with non - human or alien entities. These humans are typically the focus as they deal with the strange and often dangerous situations that come with these interactions. For example, some characters are faced with having to make difficult choices regarding their relationships with these other beings.
One of the main themes is the exploration of complex relationships. For example, in 'Bloodchild', it shows a very unusual and interdependent relationship between different species. Another theme could be survival. The characters often face difficult situations where they have to fight for their existence in strange and sometimes hostile environments.
I'm not sure specifically without more context. But it could be the bloodchild and the one who has a relationship with it, perhaps a caretaker or a protector.
There are the human characters who are sort of the 'hosts' in this strange world. And then there are the alien creatures. These two groups of characters are central to the story as their interactions drive the plot. The humans have to deal with the demands of the aliens, and there are specific individuals among the humans who play important roles in showing the different ways humans respond to this unusual situation.
Octavia Butler wrote the short story 'Bloodchild'.
The main theme could be about the complex relationship between the characters involved in this love story. It might explore how love can develop in unusual or difficult circumstances, perhaps related to the 'bloodchild' aspect which could symbolize something unique or even a bit dark in their connection.
The main theme is often about power dynamics and the complex relationships between different species. It shows how one group may have power over another in a very unusual and thought - provoking way.
It depends on your interpretation. Some might see elements of love in it, while others might not.
Since it's 'The Monster and Other Stories', there may be a group of adventurers as main characters. They might be on a quest that leads them to encounter the monster. Each of them could have different personalities and skills. For instance, one could be strong and fearless, while another is intelligent and good at solving puzzles. And of course, the monster itself could also be considered a main character in a way, as it drives the action and conflict in the stories.
I'm not sure as I haven't read the specific 'neighbors and other stories'. It could be the neighbors themselves, perhaps an old couple next door, a young family, or a single person living alone.
Given the title, it's likely that the main characters are the 'other women'. These could be women from different walks of life, each with their own story to tell. There may also be other supporting characters like friends or family members who influence or are affected by the situations these other women are in.
