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.
In Their Own Story
The cold air of the Fifth Floor seemed to emanate from Cocytus himself as he stood ready for battle. Clad in armor that blended seamlessly with his four-armed, humanoid insect form, he wielded several weapons with practiced ease. His cryokinesis allowed him to manipulate the temperature around him instantly, turning the battlefield into a frozen trap for his enemies. In the New World, Cocytus found himself leading expeditions and managing complex tribal dynamics among the Lizardmen, proving that his strength extended beyond physical combat. He approached these new challenges with the same solemn dedication he applied to guarding Nazarick's floors. Even when faced with foes who lacked the martial code he cherished, he sought to honor their spirit if they fought bravely, often leaving a lasting impression on those who encountered him.
