Obviously, the little rabbit is a main character. It's the central figure around which the story usually revolves.
In the little grey rabbit story, the little grey rabbit is the protagonist. There may be other characters such as a group of field mice that the rabbit interacts with. There could also be a big badger who lives nearby and the rabbit has to be cautious around. And of course, there might be some little insects like butterflies or ladybugs that add to the charm of the story's setting.
The main character is of course Little Peter Rabbit. His mother is also an important character as she gives him advice at the beginning which he ignores. And then there's Mr. McGregor, the owner of the garden that Peter Rabbit enters.
The main character is surely the lively little rabbit. But in a Disney story, there could be other supporting characters. Maybe there's an old wise owl that gives the rabbit advice from time to time. There could also be a group of friendly mice that the rabbit teams up with to achieve something, like finding a hidden treasure in the Disney forest.
There are two main characters in the Velveteen Rabbit story. First, there is the Velveteen Rabbit, which is a stuffed toy. It is initially just an ordinary toy but gradually becomes something more through the boy's love. The other main character is the boy. He is a child who loves his Velveteen Rabbit deeply. He hugs it, takes it to bed with him, and his feelings for the rabbit are what make the story so touching. Without either of them, the story would not be what it is.
The main characters are, as the title says, the boy and the rabbit.
The main character is surely the old rabbit. But there could also be some antagonists like a fox or a hawk that try to hunt the rabbits. These predators would play an important role in the story as they create the conflict that the old rabbit has to deal with. There might also be other animals in the forest that interact with the rabbits, either as friends or just part of the ecosystem in the story.
The rabbit is surely one of the main characters in the 'rabbit and steel story'. As for the steel, it could be seen as another character in a sense. If it's a story about a rabbit in a factory setting, then the steel structures and machinery made of steel would be important elements. Maybe there's a factory worker who also plays a role, but if we go just by the 'rabbit and steel' part, the rabbit and the steel are the main elements.
The main character is Brer Rabbit. He is a sly and clever rabbit. He is constantly getting into and out of trouble.
The main characters are obviously the girl and the rabbit. The girl could be a kind - hearted child, full of curiosity. And the rabbit, perhaps a cute little furry creature with big ears and a twitching nose.
Since I don't know the exact 'the rabbit short story', but most likely the main character is the rabbit itself.
