In many traditions, heroes are depicted as individuals who undertake quests to restore balance or protect their community, such as in Greek myths with Heracles or in Mesopotamian tales of Gilgamesh. Other cultures focus on the internal journey of the hero, emphasizing personal growth and moral lessons. Through their different functions, heroes serve as reflections of the ideals and aspirations of the societies that tell their stories.
