Eponymous characters are those whose names are the same as the title of the work in which they appear. This can include novels, films, or plays, where the character's identity is central to the story. Examples include Don Quixote from Don Quixote and Dracula from Dracula. These characters often embody the themes or conflicts of the narrative, making their names synonymous with the story itself. Eponymous characters can serve as symbols, representing broader ideas or cultural concepts, and they often leave a lasting impact on audiences and literature.
