Groundramon

Groundramon is an Earth Dragon Digimon. 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.

Attacks
 * Scrap Claw (Scrapless Claw): Holds the opponent between the arms on its back and crushes them.
 * Megaton Hammer Crush: Knocks the opponent out with the iron sphere on its tail.
 * Giga Crack: When it reaches the surface, it drops the opponent into fissures it generates by striking its whole body against the ground.
