Elder Dragon

Elder Dragons (Japanese: 古龍種 Koryūshu) are a class of monsters introduced in the first generation. Unlike other monster types, which classify monsters by shared traits, Elder Dragons are creatures that defy typical classification and sit outside of the normal ecosystem, regardless of any superficial resemblance to a dragon. These monsters are usually rare creatures with immense power that have lived since ancient times, making them more of a phenomenon than a mere animal; disasters, cataclysms, living forces of nature.
