The creature often associated with the concept of duality in mythology is the **dragon**, specifically in cultures where it represents both protective and destructive forces. In many traditions, dragons symbolize wisdom, power, and the primal elements of nature. For example, in Western myths, dragons are often viewed as malevolent beings to be slain, such as in the stories of Saint George. Conversely, in Eastern cultures, dragons are seen as benevolent entities, bringing prosperity and good fortune. This duality reflects broader themes of balance within the universe, intertwining both creation and destruction.
