- "I am Narberal Gamma, one of the battle maids, who swore loyalty to the overlord of the Great Tomb of Nazarick, the supreme being Ainz Ooal Gown. You lower life form should be honored to battle with me."
- -Narberal's introduction to Khajiit
Narberal Gamma (ナーベラル・ガンマ, Narberal・Γ) is a doppelgänger battle maid and member of the Pleiades, the battle maid squad of the Great Tomb of Nazarick. She is the creation of Nishikienrai, one of the original nine founders of Ainz Ooal Gown.
She is also known as Nabe, a magic caster and Momon's adventurer partner of Darkness. Being an adamantite ranked adventurer, she is one of the most powerful female adventurers in the Sorcerer Kingdom.
Narberal Gamma is described as an elegant, snow-white skinned, black-pony tailed beauty. People believe her beauty is comparable to that of Golden Princess.
She wears a white bonnet in place of a helmet, and black armor decorated in gold and silver in the likeness of a maid uniform. As a battle mage, her weapon of choice is a golden staff plated in silver. In her adventurer persona, she wears a plain brown cloak.
Narberal's human form is gained through her Doppelgänger's transformation skill. Due to her low-racial level, she can only transform into one form. Her original appearance as a Doppelgänger closely resembles that of Pandora's Actor.
Like many others in Nazarick, Narberal views humans as nothing more than low-class creatures. The only human exempt from Narberal's contempt is her sister Aureole Omega. Though she dislike the thought of killing humans, she will not hesitate to do so if there is no reason to let them live or unless given an order by Ainz. This nature makes Narberal one of the two, along with her sister Solution Epsilon, an "extremely dangerous" member of the Pleiades.
As a created NPC of Nazarick, she is extremely loyal to Ainz and proud of her quest to support him close by. Nevertheless, she seems unable to understand Ainz's purpose to become a hero very well, so she does not hide her aggressive attitude towards humans. At times, she would often refers to her master Ainz with a "-sama" honorific, even when the two masquerade as adventurers and order the maid to not do so.
Narberal Gamma was created by Nishikienrai to be one of the battle maids, the Pleiades. She and her sisters served as a last line of defense against intruders. However, because she is unlikely able to stand against enemy players who managed to come this far, her only real purpose was to distract the invaders until the guild members of Ainz Ooal Gown are able to fully prepare for their final stand in the throne room.

- In the Web Novel, Narberal used the Ring of Freedom, an illusion magic to become the adventurer named Momon rather than Ainz as Momon in the Light Novel.
- (To Ainz about Humans): "Humans are worthless trash."
- (To Ainz): "Ainz-sama, I am very sorry! Allow me to atone for my crime with death!"
- (To Hamsuke about Ainz): "Ainz-sama is only pretending to be a warrior, just like playing a game. If he used his real strength in magic, Armageddon would just be a small matter."
- (To Khajiit about the Supreme Beings): "Because I was created by the Supreme Being that is greater than god."
- (To Ainz): "By your command. From now on, I am no longer Nabe, and will handle this as Narberal Gamma."
- (To Khajiit): "I am not interested in the wishes of a lower life form. But your efforts are laughable. I have some words for you. Good work in being the stepping stone of Ainz-sama."
- (To Torkel): "Please witness closely with your own eyes, the legend of Momon-san, the moment a new page is written."
- (To Ainz): "I think all the proposals thought up by everyone is great! To complete a task together with Ainz-sama, I don't think there is any greater joy than that!"
- (To the Pleiades): "Evileye and myself are both elementalists. We are arcane magic casters that specialize in the use of a particular element. Although this means our attack power increases greatly, it also means that outside of our area of expertise, we are quite weak."
- (To Ainz about his change in voice as Momon): "Truthfully, I don't think this voice is good. Although it doesn't sound strange, I still think the usual voice of Momon-sa...san sounds better. While I understand there is a reason behind doing this, I admit preferring to hear your old voice."
- (To both Ainz and Hamsuke): "That is right! There is none in this world who is as generous as you are, Ainz-sama! He even spared a pathetically weak creature like you."
