Nidhoggmon

Nidhoggmon is a Digimon. It is a colossal Digimon that takes vast amounts of energy into its body, and is constantly overheating. The color emitted from its wings is its overheating level; the redder it is, the more dangerous it is. Nidhoggmon repeatedly destroys and absorbs things, leaving nothing behind in its wake.
