Avatara

Avatara (アヴァターラ) are the 37 golems that guard and protect the Mausoleum, the vault containing the World Items of the Great Tomb of Nazarick.

Appearance
Avatara are sculptures created by Momonga based on the appearance of his former guild members. According to Momonga, his lack of skill allowed him to only capture ten percent of their charm.

Momonga purchased the external appearance data and forcibly installed it into the golems. The end result is that the limbs either grew fatter or became shortened. The heads even grew massive and clown-like, like monsters from nightmares. However, this lack of cohesive unity in their appearances exude a kind of strange atmosphere which gives people a strong sense of unease.

Abilities and Powers
All the avatara are armed with super-powerful equipment of the members who had left and possess immense strength. They are designed to attack anyone who are in possession of a Ring of Ainz Ooal Gown.
