Warriors of Earth

The Warriors of Earth are AncientVolcamon and his legacy, those Digimon whose forms the users of the Spirits of Earth he 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, becoming even more powerful.

AncientVolcamon
AncientVolcamon is an Ancient Mineral Digimon whose name and design are derived from "Ancient" and "Volcano". It possesses the attribute of "Earth", and is one of the legendary Ancient Warriors that saved the ancient Digital World. It is the most powerful of the Ancient Digimon, due to the high temperature of the boiling magma within its body. Its abilities were given to the "Ore" and "Mineral" types of Rock Digimon.
