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.

Intelligent Swarm (知性を持った群体) are creatures that inhabit both YGGDRASIL and the New World.


Just as the name suggests, it is most likely a mass number of small insect monsters coming together to form a swarm.


Intelligent Swarm seems to have the capacity to carry out some form of surveillance.


  • In the Web Novel, it was mainly the Intelligent Swarm who are given the duty of observing the surroundings of the Great Tomb of Nazarick with the occasional help from Kyouhukou every now and then.[1]
