Doppelgänger

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

Appearance
Distinguishing doppelgängers from real people 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 for a 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.

Trivia

 * There have been two known Doppelgängers introduced so far, Pandora's Actor and Narberal Gamma.
