Cocytus

The honorable insectoid guardian who wields ice and steel with unwavering loyalty.

Cocytus is the Guardian of the Fifth Floor of Nazarick, an insectoid warrior defined by his unwavering code of honor. Created as part of the Great Tomb's defensive hierarchy, he takes on the form of a four-armed insectoid with a tail and a head resembling a praying mantis, and serves as a key military asset for Ainz Ooal Gown. Unlike other guardians who rely on subterfuge or complex magic, Cocytus specializes in direct combat, utilizing cryokinesis to control the battlefield with icy precision. His role has expanded significantly since arriving in the New World, where he was tasked with overseeing the Lizardmen tribes after they were defeated and surrendered.

Lore & Background

Cocytus's personality is rooted in his programming to value strength and martial spirit above all else. He shares a professional and respectful relationship with Demiurge, the Guardian of the Seventh Floor, viewing him as a capable ally rather than a rival. This relationship mirrors the dynamic between their respective creators within the Ainz Ooal Gown guild, who maintained a respectful bond. Cocytus is known for his noble demeanor; he respects any opponent who displays a strong fighting spirit, regardless of their allegiance or species.

His presence in the New World has seen him transition from a simple floor defender to a strategic leader. He was specifically tasked with managing the Lizardmen tribes after they were defeated and surrendered, demonstrating his capability beyond brute force. He gets along well with most of the other guardians, and his relationship with Sebas is respectful, with no indication of strain from their creators, who were not often at odds.
