AncientGreymon

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", such as the Greymon-species. It is said that in the previous crusade, it survived to the end alongside AncientGarurumon, and sealed away Lucemon.

It has BurningGreymon's face, torso, legs, and flaming wings. Then it has Agunimon's shoulder guards, arms and feet to form its front limbs, and it has Agunimon's long spiky hair. What appears to be the Rudriya Darpaṇa is attached to both sides of its body. It sports glowing, blue eyes. In contrast to AncientGarurumon, it is a quadruped.
