Ten Legendary Warriors

AncientGreymon is an Ancient Dragon Digimon. Possessing the attribute of "Flame", it is one of the Ten Legendary Warriors that saved the ancient Digital World. A Mega who existed only in the distant past, it is told that its strength surpasses that of current Megas, and it is certainly a "Mega" being. Its abilities were later passed on to the "Dragon Digimon" of the Greymon-species. It is said that in the previous crusade, it survived to the end alongside AncientGarurumon, and sealed away Lucemon.[4]
