Who is typically referred to as the antagonist in a story?

In a narrative, the antagonist is typically defined as the character who opposes the protagonist, who is the main character of the story. This opposition often creates conflict, which is a key element of storytelling. The antagonist can take many forms, including a person, a group of characters, or even an abstract force, such as society or nature. They challenge the protagonist's goals and desires, making the journey of the main character more dynamic and engaging.

For instance, if the protagonist is striving to achieve something important, such as overcoming an obstacle, achieving a goal, or resolving a personal conflict, the antagonist creates barriers that the protagonist must navigate. This relationship is central to the development of themes and the advancement of the plot, emphasizing the struggle and growth of the main character.
