Vilemon

Vilemon is an Evil Digimon who loves to pester and torment his opponents. It is a nasty little thing who hates being called small, tiny, or little. His Japanese name is Evilmon (which is an anagram for Vilemon).

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.

Digimon Adventure 02
Two Vilemon were partners to some unnamed French DigiDestined.

Digimon Tamers
A Vilemon bio-emerged into the Real World before Guilmon and Calumon. His efforts to intimidate the pair proved fruitless as Guilmon kept calling him tiny, which Vilemon found very insulting and started to attack using Demon Darts. Takato, Henry and Terriermon arrived to help fight Vilemon. During the battle, Rika and Renamon arrived and fought him. Vilemon overestimated himself, saying "I'd hate to fight a girl, but if you insist!", but soon became aware that Renamon was much stronger and was deleted as she attacked him from behind after he had attacked a copy of her.

Vilemon's death caused Takato to tell Rika she had killed him. Rika then retorted, saying "Digimon are nothing but data".

Digimon Data Squad
A Vilemon appeared in the Real World with three DemiDevimon, where they became the benefactor of a man who was the father of Connor, one of Marcus Damon's friends. Vilemon fed on the man's greed and disguised himself as an idol, while the DemiDevimon stacked the man's gambling efforts in his factor. When he was discovered by Marcus and Agumon, the Vilemon shed his disguise, and using the power he had gained, grew to a tremendous size. However, not even his Nightmare Shocker attack was enough to stop him from being destroyed by Agumon (Data Squad).

Digimon Adventure V-Tamer 01
Two Vilemon were seen being beaten up by Zeromaru. A bunch of them were with Neo during the invasion upon LordHolyAngemon's castle, where they were sucked into the Gate of Destiny along with the Devimon and Devidramon.
