Groundramon

Groundramon is an Earth Dragon Digimon whose name and design are derived from "Ground Dramon". It has giant arms on its back that are said to have mutated from wings, allowing it to more efficiently dig through the ground. It usually lurks within the tunnels it carved deep underground, and seldom comes to the surface. Also, as Groundramon tends to prefer to inhabit veins of the rare Huanglong ore, it has been discovered that it is very likely to find the elements of Huanglong ore comprising the scales covering its body. Its personality is extremely ferocious, and as most people lose their life when they encounter one, it is one Digimon for which the details of its ecology are not well understood.
