Spoiler Alert Spoiler Alert: WARNING! This page happens to contain a lot of heavy spoilers that are all originated from the Overlord Light Novel series written by the author Kugane Maruyama. To every Anime-only watchers and Manga-only reader out there viewing this warning, please mindfully consider your decision first before choosing to expose yourself on reading the information below. If you're not currently up-to-date with the main source material in the official books, do consider staying away from the page for non-spoiler sake until you actually read it first ahead of time.

Gargantua (ガルガンチュア) is the 4th Floor Guardian of the Great Tomb of Nazarick. Unlike the other Guardians, it is not a Custom NPC but a bonus won by Ainz Ooal Gown.


Gargantua is an ultra-large, stone golem with a height of over 30 meters. Zaryusu describes this golem as a two-armed, two-legged colossus that seemed to be carved out of stone. Its arms and legs are chunky, so it may look cute if one disregards its size. While so, its round eye sockets and chest are glowing with red lines that permeate from its chest, like a heart.


As a mindless construct, Gargantua has no personality or will of its own. Therefore, it is not able to freely move without being commanded by Ainz to do so.


Gargantua is not one of the Custom NPCs made in the Great Tomb of Nazarick, but a part of the game system.[1] The guild members gave Gargantua the position as one of the Floor Guardians in their dungeon. Gargantua usually settles at the bottom of the lake located on the 4th Floor of Nazarick.

Upon discovering Zy'tl Q'ae, Ainz noted that the treant is larger in size than even Gargantua.

When the Floor Guardians arrived at the Great Forest of Tob under Ainz's order, Shalltear acknowledged that it is a rare chance to see all of them together. However, Mare dismisses her notion, since Victim is not around to be with them on this special occasion. Accepting Mare's answer, Shalltear believes that may be the case as Gargantua is also not present with them.[2]

Gargantua being deployed.

Gargantua was activated at Ainz Ooal Gown's order. It is one of the Floor Guardians in the group to scare off the lizardmen, first by its gigantic appearance and then it strength, by throwing a large boulder onto the surface of the frozen lake.

The boulder thrown by Gargantua was where Ainz Ooal Gown had placed his throne on while present alongside almost all the Floor Guardians except Cocytus. After finishing its task, the golem immediately vanished from their vicinity presumably having returned to the Great Tomb of Nazarick.[3]

Mass for the Dead Arc

Main article: Mass for the Dead Arc

At the National Foundation Day Ceremony, Albedo announced that all the Floor Guardians were present with the exception of the golem.[4]

The Floor Guardians is briefly mentioned by Cocytus, in his self-deprecating speech of how insignificant he felt at being in charge of Nazarick's defenses in comparison to the other Floor Guardians making strides in E-Rantel for the Sorcerer Kingdom.[5]

Abilities and Powers

Shalltear Bloodfallen is called "The strongest Floor Guardian except Strategic Siege Golem, Gargantua." Thus, it makes sense that Gargantua is even more powerful than her. However, as Gargantua does not have a will nor intelligence of its own, this comparison might be meaningless. At the same time, Gargantua possesses the highest amount of stats among the Floor Guardians including Shalltear and Mare.


  • Gargantua is also a giant from French literature.
  • Its name is a variation on the word "gargantuan," meaning colossal, massive, titanic, etc.
  • According to Maruyama's conversation with the interviewer, his reason for making Gargantua is to make it fight a company of golem cavalry led by an alliance of countries in the middle of the continent.[6]
  • Maruyama stated that before Gargantua there was no Floor Guardian assigned to the Underground Lake.[7]
  • When Gargantua made its manga version debut in Comp Ace, somehow it was depicted having three bodies. This was later corrected in Overlord Manga Volume 07.
  • Due to the golem lacking a mind of its own, the Area Guardians on the 4th Floor rather than reporting their concerns directly to Gargantua, they would be transferred to Ainz Ooal Gown.[8]
  • In Mass for the Dead, the developers released an Assault Theater "Colossus Sleeping in the Underground Lake".[9]
  • According to a movie pamphlet that was released with Isekai Quartet The Movie -Another World-, Gargantua is a name that was given to the golem by the members of Ainz Ooal Gown as it was originally called "Strategic Siege Golem".
