One of the Ten Legendary Warriors that saved the Ancient Digital World, possessing the attribute of light. A Mega that existed in the far-distant past, AncientGarurumon was known as the Supreme Shining Beast. Its abilities were subsequently passed on to Beast Digimon. It survived to the end of the previous holy war along with AncientGreymon, and is said to have sealed away Lucemon. Its special moves include Sharp Claymore, where it uses its two greatswords to slice through foes in a brilliant flash of light, and Absolute Zero, by which it uses a combination of ultra-cold air at absolute zero and a superluminous flash of light to freeze all electrons in place.
