I'm not sure specifically as I haven't read the novel. But perhaps there is a brave protagonist who has to face the black snake. It could be a young adventurer or a local who is used to the area where the snake is found.
It's also possible that the black snake itself could be considered a main character in a sense. The story could be told from its perspective, showing how it hunts, how it defends its territory, and how it interacts with the human characters. This would give a unique view of the story and make the snake more than just a simple threat or symbol.
Since I don't know the exact 'the black snake story', if it's a typical one about a black snake in nature, the main character would likely be the black snake itself.
The main characters are the crow and the black snake.
One possibility could be Sebastian Michaelis, the demon butler, as the snake in a transformed state falling in love with Ciel Phantomhive. It would be a very strange and complex relationship as Sebastian's loyalty is supposed to be to Ciel in a more master - servant way, but if he were a snake in love, it would completely change the dynamic.
The 'Black Snake Killaz' are likely the group of people who were actively involved in opposing the Dakota Access Pipeline in the context of the NODAPL story. They could be Native Americans, environmental activists, or local community members who united under this name to take a stand against the pipeline.
The main theme could be about mystery. Maybe it involves the black snake as a symbol of something unknown or dangerous that the characters have to deal with.
The main characters are obviously the snake and the man. The snake represents danger or perhaps a force of nature that is not easily tamed. The man is the one who tries to interact with the snake in some way.
Often, there is a male protagonist who might be a curious traveler or a brave warrior. He might be the one who has a special encounter with the snake woman. His actions and reactions towards her are crucial in driving the story forward. He could either fall in love with her, despite her snake - like nature, or try to defeat her if he perceives her as a threat.
The main characters are, obviously, the girl and the snake. The girl is likely a symbol of innocence or perhaps ignorance in the story. And the snake, which is often seen as a symbol of cunning or danger in many stories from different cultures.
In the boy and the snake story, the two main characters are a boy and a snake. The boy is likely a naive or kind - hearted character who stumbles upon the snake, which is a symbol of danger or deceit in the story.
The main characters are an Indian and a snake. The Indian is probably a human figure who has some sort of encounter or relationship with the snake, which forms the basis of the story.
