Devimon

Devimon, also known as "Darkmon", is a Fallen Angel Digimon whose name is derived from the Devil. It was once an Angemon, but it was corrupted when the Digital World became distorted and it fell into the Dark Area. The symbol on its chest is a mark of evil that symbolizes his wickedness. It is a cunning Digimon who does not take risks, and refuses to join in mindless fighting with opponents as powerful as itself. It is also wicked and ferocious, but loyal to the master with whom it has made a pact or more evil than itself. It is said that staring into its crimson-evil eyes will grant it control over your mind. Devimon is also known as the "Dark Messenger". It is one of the few villains to have its own image song. It is entitled "Dark Wing" and ends in a villainous laugh.
