Shakkoumon

Shakkoumon is a Mutant Digimon whose name and design are derived from the mythological. It DNA digivolved from Ankylomon and Angemon. It possesses white wings on its body, which shines silver, 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.
