Doppelgänger

Doppelgängers (ドッペルゲンガー, Dopperugengā) are a race of shape shifters from YGGDRASIL.

Appearance
Distinguishing a doppelgänger from a real person is difficult due to their shapeshifting abilities, but the original appearance of those from YGGDRASIL seems to be humanoid with thin claw-like hands. However, their faces resemble that of an egg with three holes in the place of its mouth and eyes.

Abilities
Doppelgängers are masters of shapeshifting. With the right skill, they are capable of transforming their bodies to take on any form they wish.
