AncientVolcanomon

AncientVolcanomon is an Ancient Mineral Digimon whose name and design are derived from "Ancient" and "Volcamon". It possesses the attribute of "Earth", and is one of the legendary "Ten Legendary Warriors" that saved the ancient Digital World. It is the most powerful of the Ancient Digimon. There is always high temperature magma welling up inside its body, which becomes the source of its mighty power. Its abilities were later passed on to the "Ore" and "Mineral" types of Rock-species Digimon.
