The character who opposes the protagonist is referred to as the antagonist. This character serves as a foil to the protagonist, creating conflict and tension within the narrative. The antagonist's motivations, goals, and actions are typically in direct opposition to those of the protagonist, thereby driving the story forward. They can take many forms, including individuals, groups, or even abstract concepts like society or nature.

In literature and film, the quality of the antagonist often enhances the depth of the story, as the conflict between the protagonist and antagonist becomes a central element that engages the audience. A well-developed antagonist provides not only a challenge for the protagonist but can also evoke sympathy or understanding, making the narrative more complex and relatable. This dynamic is crucial for exploring themes such as good versus evil, personal growth, and the moral dilemmas faced by the characters.
