Shakkoumon

Shakkoumon is a Mutant Digimon whose name and design are derived from the mythical Shakōkidogū. It DNA digivolved from Armadillomon and Angemon. It possesses white wings on its shining, silver body, and according to one theory it is an Angel Digimon which descended to the Ancient Digital World. It can rotate its neck and torso 360°, allowing it to attack in every direction. As its face is expressionless it is difficult to determine what it's thinking, so some observers find it eerie, but its personality is exceedingly gentle.
