In terms of its powers, Chinese dragons are a little different than the dragons of European traditions. While European dragons are evil, greedy, or malicious, Chinese dragons are benevolent and wise. They are powerful, dangerous and should be respected, but they are inherently good.
Through their willpower and role as the mightiest of spiritual creatures, they can control rain, floods, rainbows and other natural events; they can bring good or bad luck, and are known to transport humans to the afterlife. However, what may most characterize the dragon is its association with transformation. The dragon represents change and adaptability, and in fact can change its physical form. So, trying to identify a dragon purely by its appearance is unwise.
Dragons throughout Chinese mythology are more often described by their personality, which does not change regardless of physical form. A dragon is wise, ambitious, and energetic, These qualities, plus an innate divinity and spiritual power, are what really define the dragon.
