Spoiler Alert Spoiler Alert: WARNING! This page happens to contain a lot of heavy spoilers that are all originated from the Overlord author, Kugane Maruyama and his collection of written works. Anime-only watchers and Manga-only readers, please take some time off to reflect it over for a bit before choosing to expose yourself on reading the information below recklessly.

NoImage Alert Judging from the current state of this page, there is no available image on the Overlord Fandom as of yet to help emphasize its appearance. Since it is lacking visuals, this article requires an image for the first time, the kind which should be high quality and distinguishable. You could go out of your way to assist the Overlord Wiki by adding an official image that came from any Overlord adaptation to it.

Dullahans (首無し騎士) are a race of undead from YGGDRASIL.


Dullahans are a headless corpse that carries its decapitated head. They can vary from chalk-white skin to rotting flesh. While normally seen carrying their heads, some Dullahan can attach their heads back to their necks by way of a ribbon or choker or collar; a preferable way for a player with Dullahan avatars.


A Dullahan is similar to an animated corpse like a zombie; but unlike zombies, Dullahan are immune to decapitation because of their detachable heads.[1] Being an undead, they are also immune to poison and negative energy.[2]
