Vilemon

Vilemon is an Evil Digimon whose names are derived from "Evil" and "Vile", and whose design is derived from the mythological imp. It abhors losing, so it is a coward that torments the weak with pricks, without getting into direct combat. It seems it is credited as being the source of the Dark-species Digimon that inhabit the Dark Area, but there are still many mysteries.

Digimon Adventure
After an altercation with MagnaAngemon, Piedmon summoned his horde of Vilemon to battle the DigiDestined. Luckily, Mimi and Lillymon arrived with Unimon, Ogremon, Frigimon, Meramon, Elecmon and some Gekomon and Otamamon. Each of the Vilemon were defeated by the DigiDestined Digimon and the allied Digimon in a battle that culminated when MagnaAngemon sucked up the Vilemon with his Gate of Destiny attack.
