Arukenimon

Arukenimon is a Demon Beast Digimon whose names and design are derived from the mythological "Queen of Spiders", Arachne. As the queen which supervises all Dokugumon, it is an extremely cunning Digimon with great intelligence. It is skilled at transforming into a human-like appearance, getting the opponent to let down their guard so that it can approach and completely devour them. Also, because of its extremely short temper and brutal personality, many Digimon are afraid of it.
