Gargantua

Gargantua is a supporting protagonist from the light novel series, Overlord. It is a massive golem-like creature that serves as the Floor Guardian of the 4th Floor of Nazarick.

Appearance
Gargantua is a behemoth of a monster with a rock-like appearance. It appears to have red glowing eyes and streaks of red lights that drag down on its face. The same red glow carries over to its chest.

Personality
Gargantua appears to be a completely mindless creature, as it is unable to communicate and act on its own. It does nothing but follows Ainz Ooal Gown's orders, obediently.

Prior Events
While most NPCs were created by the Supreme Beings, Gargantua is a unique exception, as it was given to Ainz Ooal Gown as a gift by the Game Administration. Some time later, it was eventually given the role as the Floor Guardian of the 4th Floor.

The Lizard Man Heroes Arc
Gargantua briefly appeared when Ainz Ooal Gown visited the Lizardmen village for the first time. It tossed over a massive boulder into the water for Ainz and the other Floor Guardians to present themselves to the Lizardmen. Gargantua soon disappeared afterwards.

Powers and Abilities
Gargantua is implied to be the strongest of all the Floor Guardians, as it was stated that his stats surpass all of the others, including Shalltear's. While Gargantua has yet to demonstrate its full capability, it has shown off the following:
 * Superhuman Strength: Gargantua has such immense strength that it was able to pick up a boulder the size of its body and throw it over at a far distance.
 * Superhuman Durability: Because of its massive size and high stats, it can be assumed that Gargantua possess durability that surpasses humans beyond.
