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

Attacks
 * Gaia Tornado: Gathers the spirit of the land and creates a tornado to swallow up the opponent and blow them away.
 * Omega Burst: Induces a super-detonation over the surrounding kilometers alongside an intense flash.

Design
AncientGreymon appears to be a mish-mash of both Agunimon and BurningGreymon, its form containing physical features from the Human and Beast Spirit Digimon of Flame. 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 Rudyri Tarpana is attched to both sides of its body. It sports glowing, blue eyes. In contrast to AncientGarurumon, it is a quadruped.
