One of the Ten Legendary Warriors that saved the Ancient Digital World, possessing the attribute of fire. A Mega that existed in the far-distant past, AncientGreymon is said to have been a Mega in every sense of the word, even more powerful than Megas of the modern era. The abilities of AncientGreymon would later be inherited by the Greymonｰspecies and other Dragon Digimon. It survived to the end of the previous holy war along with AncientGarurumon, and is said to have sealed away Lucemon. Its special moves include Gaia Tornado, where it concentrates the power of the earth to form a tornado that it uses to blow away foes, and Omega Burst, which involves creating a massive explosion along with an intense flash of light, both of which extend for miles around.
