Heroes typically undergo significant transformations in their journeys, often evolving both physically and morally. They face trials that challenge their character, resulting in personal growth and enlightenment. For instance, heroes may start as flawed individuals, confronting their fears and mastering new skills, thus emerging stronger and wiser. This journey often leads to fulfilling a prophecy or achieving a greater purpose, reflecting the universal themes of struggle, resilience, and the pursuit of one's destiny found throughout mythological tales.
