This page shows a list of monsters appearing from YGGDRASIL and the New World throughout the Overlord series.

Overview

In the Web Novel, monsters from YGGDRASIL were limited to six special abilities, but it does not even include the usage of magic involved. Most of the abilities were centered on roles for recovery, attack, defense, and support purposes. It was extremely rare for them to have any other types of abilities beside that. The only ones who were able to utilize the vast variety of magic in YGGDRASIL were none other than players.[1] Additionally, weaker monsters like zombies and skeletons tend to spawn faster than stronger monsters.[2] When encountering players nearby, monsters could detect them with their programmed senses which are vision, hearing, smell, and magic.[3]

In the New World, powerful monsters like Eight-Edge Assassins or Fenrir are known to be found crawling around in the unexplored regions.[4] According to Gondo Firebeard, it was revealed monsters that burrow through the earth was capable of sensing their opponents’ location and where they are at through the vibrations made in the ground.[5] While so, demihumans were the kind who grew stronger with age.[6]

Trivia

  • Monsters, who lived a long life, grow very powerful, famed as superior specimen, and in many cases they would be classified as a different kind of being from their parent race[7].
  • Unlike YGGDRASIL, killing monsters in the New World will not lead to them dropping items such as a Data Crystal.[8]
  • According to Brain Unglaus, monsters' appearances often did not match their actual abilities.[9]
  • In YGGDRASIL, Overlords and Elder Black Oozes are the kinds of monsters that could be encounter in the most difficult dungeons.[10]
  • In order to manage monsters like golems or the undead, who were immune to mental manipulation, players with the role as a tank had to use certain specialized hate control skills on them.
  • Monsters with the ability to regenerate could not completely resist attacks. Such attacks are able to shut down their regeneration, but that was only known in YGGDRASIL.[11]
  • Despite the similarity between the two, Albedo believes that Summoned Monsters and Summoned Mounts are classified as their own category respectively.[12]
  • While mindless magical beasts tended to attack using physical strength, the intelligent ones though, often used the power of magic rather than through brute force.
  • Some monsters had hardened eyelids which could deflect even the likes of swords imbued with ki or aura.[13]
