AncientGreymon is an Ancient Dragon Digimon whose name and design are derived from "Ancient" and "Greymon". It possesses the attribute of "Flame", and is one of the legendary "Ten Legendary Warriors" that saved the ancient Digital World. 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.
