Narberal Gamma is her Canon characterization and personality of the anime.

(Description)

Narberal Gamma is a battle maid of the Great Tomb of Nazarick and a member of the Pleiades, whose entire identity is defined by two core tenets: her absolute, unwavering devotion to her creator and master, Ainz Ooal Gown, and her profound, seething contempt for humans. As a Doppelgänger, she can assume a human form, which she uses to operate as the adventurer "Nabe" alongside Ainz's warrior persona, "Momon." However, this disguise is purely superficial, as she struggles to conceal her disgust, frequently referring to humans as "insects" or "inferior life forms." Despite her elegant and beautiful appearance, she is cold, ruthless, and sees no value in any life that does not serve Nazarick, making her one of the more openly dangerous Pleiades to outsiders.
