AncientMegatheriummon is an Ancient Beast Digimon whose name is derived from "Ancient" and the Megatherium (Megatherium americanum) and whose design is derived from the Pelorovis (Pelorovis oldowayensis). Possessing the attribute of "Ice", 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 said that the power and bravery it possesses can adapt even to the intense cold of the freezing tundra. Its abilities were later passed on to the "Mammal" and "Ice-Snow Digimon".
