Fictional archetypes are universal character types or themes that recur across different stories and cultures. They serve as templates that help readers quickly understand a character's role and motivations. Common examples include the Hero, the Mentor, the Villain, and the Trickster. These archetypes can be found in literature, film, and folklore, making them recognizable and relatable. These archetypes often embody specific traits or journeys, such as the Hero's quest for self-discovery or the Mentor's guidance. By using these familiar patterns, writers can create engaging narratives that resonate with audiences, allowing for deeper connections to the story and its characters.
