In Western fairy tales, dragons are something for knights to defeat, but in the East, they symbolized kings or were seen as divine animals that brought rain. So, besides the common trait of "powerfulness," their image varies by culture.

Recently, in K-pop idol concepts or fantasy genres, the dragon often appears as a symbol of charisma and mystery. People might metaphorically praise someone outstanding or cool by saying they are "like a dragon." Try using it when you want to express overwhelming power or a special presence, not just an animal.
