Monsters

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 besides that. The only ones who were able to utilize the vast variety of magic in YGGDRASIL were none other than players.Overlord First Half Chapter 18: Categorical Imperatives Additionally, weaker monsters like zombies and skeletons tend to spawn faster than stronger monsters.Overlord First Half Chapter 34: Preparations 3 When encountering players nearby, monsters could detect them with their programmed senses which are vision, hearing, smell, and magic.Overlord Blu-ray 06 Special: Prologue (2nd Half)
In the New World, powerful monsters like Eight-Edge Assassins or Fenrir are known to be found crawling around in the unexplored regions.ARCADIA 2.56: ARCADIA 3122 09-29-2011 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.Overlord Volume 11 Chapter 2: In Pursuit of the Land of the Dwarves While so, demi-humans were the kind who grew stronger with age.Overlord Volume 11 Chapter 5: Frost Dragon Lord
