Warriors of Earth

The Warriors of Earth are AncientVolcamon and its legacy, the Digimon whose forms the users of the Spirits of Earth it left behind can take. Those who use the Spirits of Earth have the ability to combine with each other or with Spirits of other elements and become even more powerful.

AncientVolcamon
AncientVolcamon 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.
