Arukenimon

Arukenimon is the romanization of her Japanese name Archnemon. She was based on Arachne, the woman from Greek mythology who was turned into a spider by Athena as punishment for boasting of being a better weaver.

Arukenimon is a Digimon in the form of a spider courtesan Yōkai, Jorōgumo, with the head and torso of a woman and the abdomen and legs of a spider. Queen of the Dokugumon, her quick tempered personality makes her feared by most Digimon.

Her special ability is to transform into the form of a beautiful woman so she can draw close to her victims. In her human form, she can use her hair-strands in her 'Spirit Needle' spell on Control Spires to create artificial Digimon that obey her command as long as they are of the same level or below it (this explains why she could not control BlackWarGreymon, who was a powerful Mega level Digimon). In Digimon Adventure 02, Arukenimon can also control any insect Digimon by playing a special tune on a flute she possesses.
