An Ancient Digimon proved to have existed long, long ago, thanks to a multitude of evidence. The warming of the Digital World defrosted some hyper-compressed data, causing it to appear in icy areas where the thaw had melted. Its whole body is covered in thick fur, and although it possesses tremendous, ancient power, Mammothmon is extremely susceptible to fire damage. The crest carved onto its face mask is a crystal of super-ancient wisdom, and it possesses a second sight that allows it to see long distances. Mammothmon’s large ears can even discern sounds in far-off places. Its special move Tusk Strikes stabs at the enemy with its two long tusks, and Tundra Breath blows a gust of chilly air from its long nose.
