Undead (アンデッド) are creatures that have come back to the land of the living after dying and are found both in YGGDRASIL and the New World.


In YGGDRASIL, undead was one of the many races a player can choose to be. Moreover, such race is divided into different subspecies according to their racial level, allowing players to further evolve beyond it. This goes along well with the right classes specifically that are befitting for someone who was an undead. A Necromancer for starters was a class that allowed one to turn a corpse into an undead as their own slave.

However, the quality of the undead produced can vary depending on the species of the corpse especially ones in the New World. The best corpses were those of powerful beings like dragons, while human corpses could become zombies and skeletons. This was shown, when an undead player such as Ainz is able to turn a mere human corpse into the form of a Death Knight. Amidst their ranks are also Skeletal Dragons. Other than these undead, there are also some of the Dragon Lords in the New World who may possibly be one according to Zesshi Zetsumei.

For Ainz, he is able to spawn an undead out of thin air by using one of his many abilities as Overlord, a high-tier race. Yet the undead created were only able to stay in the New World temporarily since it wasn't done with a corpse or any parts of its body, which create a permanent undead. Even mid-tier or higher-tier undead monsters can spawn a weaker undead through the person killed by them. Depending on the undeads' abilities like Crypt Lord or Overlord, they are also able to make their own weak undead minions stronger than normally was supposed to be while controlling them.

On the other hand, the undead are looked upon as monsters that possess an undying hatred for all living creatures. The undead are considered to be the enemy of all living beings. Yet, there are few exceptions to this idea in which Ainz Ooal Gown and Davernoc, who doesn't see it the same way they do, but was still indifferent to them nonetheless in terms of not being able to show emotions physically. Whenever Ainz issues mental commands over the weaker undead, they won't be able to easily attack the living out of their nature unless it was ordered to do so.

Therefore, despite having such hatred towards the living, some of the undead are able to reach a mutual understanding with them to some extent. Certain sentient undead were capable of suppressing their hatred in order to negotiate. If the living were the ones who try to offer negotiation first, then it would usually end up turning out to be a bad trade. But if the undead were to initiate the first offer or negotiation, there had once been instances of people obtaining ancient items that had been made with now-forgotten knowledge.

While so, the undead do not age, so they would continue ruling the land for all eternity until it was defeated. Unlike the dragons' own growth rate, high-level undead are not the type to grow in bodily might. They could instead accumulate knowledge and experience constantly over time. From that point of view, the undead might be even stronger than dragons. When a group of weaker undead gather in one place, stronger undead are then created after a certain period of time passes by. For example, a Death Knight spawning in the Katze Plains.

In the New World, it seems there are legendary tales recorded and passed down about the undead. One being the Soul Eaters, which devoured the souls of the living. While another case being the Wriggle Pestilences, which spread disease. Additionally, there are mage cabals which gathered many undead around a core of Elder Liches for instance. And then there was Guphandera Argoros, the undead dragon that lurked in a mountain of the dead and is a user of psychic-type magic. Not only that, but this also includes the Astral Rippers, masses of shadows which stalked the Valley of Shadows, and so on.
