What is an antagonist?

An antagonist is defined as a character or force that opposes the protagonist, who is typically the main character of a story. This opposition creates conflict, which is essential for driving the narrative forward. The role of the antagonist can be filled by a character, like a villain, or it can be represented by a situation or a societal force that challenges the protagonist.

Understanding the function of an antagonist is crucial in literature because this conflict is what often catalyzes the protagonist’s journey, whether that journey involves growth, change, or overcoming obstacles. The tension generated between the protagonist and antagonist helps to engage readers and deepen the narrative's themes.

In contrast, the other options focus on character dynamics that do not characterize an antagonist properly. A character who supports the protagonist typically acts as a confidante or ally, while the main character is not defined by opposition but rather by their central role in the story. Furthermore, the setting encompasses the time and place in which the story occurs, which does not inherently involve opposition to the protagonist.
