Dullahans (デュラハン、) are a race of undead from YGGDRASIL.

Appearance Edit

Dullahans are a headless corpse that carries its decapitated head.

Abilities Edit

A dullahan is similar to an animated corpse, like a zombie, but unlike zombies however, they are immune to decapitation. That is because they are able to detach their heads at will.[1] Being an undead, they are also immune to poison and negative energy.[2]
