GA.png Non-Canon: REMINDER! This page is considered as among one of the many pure game contents found exclusive in Mass for the Dead only. It includes the new standalone characters that had a first-time appearance in the game. Meanwhile, the old characters had a different role and fate than from the main storyline in the official books. For that reason, it has no connections to the canon story materials of Overlord Light Novel series. The content that you had read here are based on the Overlord mobile game.

NoImage Alert.png 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. Unknown Intruder, you could go out of your way to assist the Overlord Wiki by adding an image that came from any Overlord adaptation to it. It cannot be a fan-art or fan-made. You must upload the official ones visually drawn by the main producers of the light novel, manga and anime adaptations.

Monster Parasite is the tentative name of a monster that appears in Mass for the Dead.


There are no details on its appearance though it appears to be very small.


A very rare monster that exists in the New World, that infests armor and feeds on the magical energy as sustenance. The parasite can also infest other inanimate items like swords. If there is enough magical energy, the parasite can use these objects as vessels and even move on their own.


  • In the game Mass for the Dead, one was found in a deep cave southeast of the Katze Plains by iron adventurers. The monster inhabited a sword that was embedded in the rock. When one of the adventurers sought to remove it, the sword moved on its own. Scared of such a phenomena, the adventurers fled and told their story to their fellows in the Adventurer's Guild in E-Rantel. Since it moved on its own, it was believed that the sword was one of the Four Swords of Darkness wielded by the Black Knight, specifically Hyumilis. The adventurers Lakyus, Gagaran and the Swords of Darkness journeyed there to confirm that it was truly a magical sword.[1]
