Hydramon is a Dark Dragon Digimon whose name and design are derived from the Lernaean Hydra. It is an Orochimon that underwent Digivolution upon murdering a noble hero among Digimon. The insensate, phantom heads of Orochimon now have their own personalities and behavioral patterns, and Hydramon chooses to keep only a few showing at a time due to the heads' constant bickering.
- Lernaean Inferno: Hydramon incinerates the foe with flames hot enough to make liquid magma evaporate.
- Herculean Slicer: Hydramon slices the foe to thin shreds with its sword-shaped tail.
