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. Its arms and legs are chunky, so it may look cute if one disregards its size. A red glow permeates from its chest, like a heart.

Personality
Gargantua has no personality or will of its own, being a mindless construct.

Background
Gargantua is not a custom NPC, but a bonus given by the Game Administration. The guild members named it as one of the Floor Guardians, though it 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 to place his throne on. It 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.

Trivia

 * 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.
