Antagonists are characters in a story who oppose the protagonist, creating conflict and driving the narrative forward. They can take many forms, from a villain like Darth Vader in Star Wars to a more abstract force, such as societal norms or internal struggles within the protagonist. Their role is crucial, as they challenge the main character, forcing them to grow and evolve throughout the story. In literature and film, antagonists can be complex figures, often possessing their own motivations and backstories. This depth adds richness to the narrative, making the conflict more engaging. Examples include Iago from Othello and The Joker from Batman, both of whom embody the multifaceted nature of antagonism.
