From Wikimon

A Beast Digimon with a strong sense of territoriality. It builds its nest in places that differ in elevation such as cliffs or rocky mountains. Its characteristic rocks, which cover a portion of its skin, regenerate and become harder each time they break. In addition, the individual with the hardest rocks within a troop is the alpha in charge of their territory.
Its Special Moves are hurling the rocks on its arms (Mount Stone), and striking the enemy with its rock-covered tail at tremendous speed (Glide Rocks). jjjjjj
