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.

Background
Gargantua is not a Custom NPC, but a bonus given to Ainz Ooal Gown by the Game Administration. The guild members given it the position as one of the Floor Guardians in the Great Tomb of Nazarick. 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 came along with the Floor Guardians to scare off the lizardmen by throwing a large boulder onto the surface of the frozen lake for Ainz Ooal Gown to place his throne on. The golem immediately vanished after completing its task.

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. While at the same time however, Gargantua also possesses the highest amount of stats than any other Floor Guardians including the likes of Shalltear and Mare.
