Arukenimon was one of the main antagonists of Digimon Adventure 02 and is a Digimon in the form of a spider courtesan Youkai, 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 made 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 Mega Digimon and a powerful one at that). In Digimon Adventure 02, Arukenimon can also control any insect Digimon by playing a special tune on a flute she possesses.
