Mammothmon X is an Ancient Animal Digimon and carrier of the X-Antibody. Mammothmon had several tens of percent corrupted data or higher when it expanded from its super-compressed data, but it restored up to 99% of it as a result of its self-repairing ability increasing due to the effects of the X-Antibody, and has become a near-perfect figure of a Mammothmon that lived in ancient times. The mask covering its face has reached as far as its back and abdomen. So, not only is its appearance exhibited in perfect condition, but also its abilities due to the crest engraved into its mask, and it has been proven that it has started instinctively tracking down Virus-species as it discovers them. Based on these facts, Mammothmon is thought to have been a Virus Hunter Digimon in the harsh Ice-Snow Area.[1]


  • Tusk Strikes: Skewers the opponent with its two elongated tusks.
  • Tundra Breath: Spews cold breath out of its long trunk in one burst, instantly freezing any opponent.
  • Geometric Freezer: A barrier that freezes only Virus-species with the cold air released from its nasal cavity.


Mammothmon X is an altered version of Mammothmon.
