 * - Ainz announcing his goals, setting all of Nazarick into motion

Ainz Ooal Gown (アインズ・ウール・ゴウン), formerly known as Momonga (モモンガ), is the main protagonist of the Overlord. He is the guild master of Ainz Ooal Gown and regarded as the highest of the 41 Supreme Beings by the NPCs of the Great Tomb of Nazarick.

Appearance
Ainz Ooal Gown has an appearance of a Lich, an undead skeleton creature devoid of skin and flesh. He wears an elaborate, jet-black academic gown adorned with gold and violet edges. He has a dark red glow inside the empty eye sockets, and a dark halo-like object glimmered behind its head.

In his dark warrior persona, he wear a fully black body armor with purple and golden markings. He has a red cape on his back with two large swords.

Personality
A cautious and stingy person, Ainz always tries to plan and control details, avoiding any haphazard actions. Because he doesn't underestimate his opponents, he will usually overkill them. Since being transferred to a new world and becoming an actual Undead being, Ainz could feel himself becoming very cold and calculating, his emotions repressed.

Loyal to his friends and creations, since becoming Lord ruler of Nazarick in the new world he acts with a certain degree of nobility for his devoted followers. Ainz only does things that will benefit Nazarick or himself, whether its information or prestige. Although he does have a sense of justice and doesn't hate humans as much as his followers, he holds no attachment to them, and he feels nothing toward their deaths.

Background
When Ainz started playing YGGDRASIL he was very close to quitting since playing one of the Heteromorphic Races he was seen as a monster by other players that only by existing deserved to be killed. Saved by Touch Me, the two of them together with seven others started the PVP/PKER guild Ainz Ooal Gown seeing as the other players viewed them as evil beings, they thought it was only proper that they became real monsters.

Because of Ainz not having any family or friends he dedicated his whole life to the game and his guild. He would use all the money and time he could spare to play it. Even though all the other members had left he stayed and kept the guilds base called The Great Tomb of Nazarick up and running, in the hopes that they would one day return to the game.

The Undead King Arc
Momonga, guildmaster of Ainz Ooal Gown, is conversing with Herohero during the last moments of YGGDRASIL. Herohero bids farewell to Momonga and logs out. Momonga is enraged about his friends leaving the game, but cools down after noting that they didn't abandon the guild - it was that they had real life issues to deal with. Still engrossed in the memories of the past, he takes the Staff of Ainz Ooal Gown before heading to the throne room.

He encounters Sebas and Pleiades at the Royal Suite and calls for them to accompany him. At the throne room, he discovers Albedo holding World Class Items. While he is initially irritated that her creator Tabula Smaragdina broke the guild rules, he quickly forgives him since Albedo was one of his treasured creations. Momonga looks through her settings and reprograms her to be in love with him. Without little time left, he sits at the throne and points at the banners, calling out the names of his guild members while waiting for the server to shut down. Unexpectedly, the server does not shut down and Momonga quickly realizes that something is wrong when the NPCs begin talking. Staying calm, he orders Sebas to survey the surrounding and orders Albedo to assemble the floor guardians at the sixth floor. Brooding to himself, he concludes that all of the NPCs have gained sentience and agonizes over Albedo's modified settings.

Momonga went to the Amphitheater of the six floor and meets with Aura and Mare. He asked the two that he is testing the Staff of Ainz Ooal Gown. After the experiment he summoned the Primal Fire Elemental and asked Aura if they want to fight it which Aura agree and along with Mare. After that the arrival of the floor guardians are now assemble and pledge their absolute loyalty to Momonga. After confirming their loyalty Momonga went back to the Throne.
