Woodmon

Woodmon is a Vegetation Digimon and is the digivolved form of Mushroomon. Because their bodies are made of wood, they can easily catch fire and thus greatly fear fiery Digimon, although this is a downside, the bark acts like armour to most other attacks. With a ferocious personality, Woodmon are known to disguise themselves as trees to absorb the energy from other unsuspecting Digimon.

Digimon Adventure
Several Woodmon lived in the forests of the Digital World and sucked the energy from anyone passing by. One of this was Ogremon, who however fought against and destroyed several of them but was quickly outnumbered by the Vegetation Digimon. Suddenly the meteor containing MetalEtemon crashed down on the remaining Woodmon, sending Ogremon off the cliff he was standing on. Later on several other Woodmon seemed to work for the Dark Masters since they fought against Leomon.
