An American scholar Joseph Campbell acknowledged an outline of narrative called The Hero's Journey that appears in theatre, drama, myth, religious ritual, storytelling and emotional growth. The Hero, goes out and accomplishes great deeds on behalf of the tribe, community, group or civilization. Crossing the threshold into adventure he leaves his everyday world for the first time. The hero learns the rules of his new world and officially begins his journey, he meets a helper or mentor and together they cross the threshold. He reaches a point where he has no option of turning back, and he generally encounters trials, allies and enemies. The hero is shown against a background of environs, inheritance, and personal history. The different stages of adventure recognized is called the "hero's journey."
Classics such as Beowulf and Odysseus epic tales such as Batman follow the same path of the hero’s journey.
