A protagonist is the main character in a story, often facing challenges and driving the plot forward. This character usually has goals, desires, and conflicts that make them relatable to the audience. For example, in the classic tale of Cinderella, she is the protagonist who overcomes adversity to find happiness. The protagonist can be a hero or an anti-hero, depending on their traits and actions. In Harry Potter, for instance, Harry is a brave protagonist who battles against dark forces. Readers often connect with the protagonist's journey, making them a crucial element in storytelling.
