A gigantic Vegetation Digimon that primarily settles in swamps. Hydramon excretes a deadly poison from every part of its body, which it mercilessly uses on prey to liquefy and then eat it. It also spews out large amounts of the same toxic substance from its chest, turning the earth into swampland, extending its territory. Such swamps warp the surrounding flora and fauna, so be on the lookout for Hydramon if you run across an area with mutated and twisted plant life.
Its special moves include Biotoxin, where it releases a poison gas from the mouth on its chest, and Scatterblaster, where it fires beams wildly from its three heads. Finally, it has Fault Break, where it spreads its vines deep into the ground and violently shakes them, creating fissures that destroy both land and enemy alike.
