Gargantua

Gargantua (ガルガンチュア) is the 4th Floor Guardian of the Great Tomb of Nazarick.

Appearance
Gargantua is an ultra-large, stone golem with a height of over 30m. Zaryusu describes this golem as a two-armed, two-legged colossus which 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, a red glow permeates from its chest, like a heart.

Personality
Being 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.

Background
Gargantua is not one of the Custom NPCs made in the Great Tomb of Nazarick, but a bonus that was gifted to Ainz Ooal Gown by the Game Administration. The guild members given it the position as one of the Floor Guardians in their dungeon. Gargantua usually settles at the bottom of the lake located in the 4th Floor of Nazarick.

The Lizard Man Heroes Arc
Gargantua was activated and is one of the Floor Guardians in the group to scare off the lizardmen 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.

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 also possesses the highest amount of stats than any other Floor Guardians including Shalltear and Mare.
