AncientSphinxmon is an Ancient Mythical Animal Digimon. Possessing the attribute of "Darkness", 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 set at the opposite extreme to AncientGarurumon as a being born from darkness. It rules over the destruction and annihilation of all existing or living things, and is feared as the "Deadly Dark Beast". Its abilities were later passed on to the "Mythical Animal" and "Demon Beast Digimon".[3]
