What is the role of an antagonist in a story?

The role of an antagonist in a story is to oppose the protagonist, who is often the main character or hero of the narrative. This opposition can manifest in various forms, such as through direct conflict, challenges, or creating obstacles that the protagonist must overcome. The antagonist can be a person, group, or even an abstract force like nature or society itself. By presenting counterforces or conflicting goals, the antagonist drives the plot forward and adds depth to the protagonist’s journey, making their eventual successes or growth more impactful. The presence of an antagonist often leads to tension and dramatic conflict, which are essential components of storytelling, providing a catalyst for character development and thematic exploration.
