The main characters are the shepherd boy and the wolf. The shepherd boy is the one who takes care of the sheep and the one who cries wolf, and the wolf is the predator that threatens the sheep.
The shepherd boy and the wolf are the main characters. The shepherd boy plays a central role as he is the one whose actions drive the story forward. He's responsible for the flock and his false alarms about the wolf are the main plot device. The wolf, on the other hand, is the feared antagonist. It represents the real threat to the sheep and is the reason why the shepherd boy's false cries are so dangerous. Without these two characters, the whole essence of the story, which is about honesty, false alarms, and the consequences of lying, would not exist.
There are two main characters. First, the shepherd boy, who is in charge of the flock of sheep. He's a bit mischievous as he repeatedly lies about the presence of a wolf. Second, there's the wolf. It's the source of the potential danger to the sheep. It's the element that makes the shepherd boy's lies seem so serious and the situation so dire when it finally shows up.
