 * - 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 series. He is the guildmaster of Ainz Ooal Gown, Overlord of the Great Tomb of Nazarick and the creator of Pandora's Actor. He is regarded as the highest of the Almighty 41 Supreme Beings by the NPCs of Nazarick.

In the New World, he is the Sorcerer King of the Sorcerer Kingdom and the most powerful magic caster in the world. His other identity is famously known as Momon, a dark warrior and leader of Darkness, an adamantite ranked adventurer group of that nation. He is an adamantite class adventurer and the strongest adventurer in E-Rantel.

Appearance
Ainz Ooal Gown has the appearance of an Overlord, an undead skeleton creature who is devoid of skin and flesh. Ainz 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 as Momon, Ainz would wear a fully jet-black body armor with purple and golden markings on it. He wears a red cape and along with two large swords on his back while carrying it behind him.

Personality
While being a cautious and stingy person, Ainz would always tried to plan ahead and control details beforehand in order to avoid any haphazard actions that can endangers Nazarick's existence. This means going so far as lying to the inhabitants in the New World that he can't used one of his Super-tier spells for years to come after using it once. Another lie being that a Sealing Crystal could create devastating aftereffects upon using one. Since being transferred to a new world and becoming an actual undead being, Ainz could feel himself becoming very cold and calculating while his emotions repressed.

To take into consideration, he loves to reminisce about the wise words from his fellow guildmates as they may hold some meaning now, which the NPCs believes it so too. As he is loyal to his friends and the NPCs created by them, Ainz has become a ruler of Nazarick in the new world. This was where he then acts with a certain degree of nobility, leading his devoted followers so they can faithfully have a Supreme Being to look up to and depend on. Nevertheless, Ainz is paranoid and pessimistic that his Floor Guardians or other NPCs that follow after them may someday abandon him if he doesn't lived up to their expectations.

He only does things that will benefit Nazarick or himself above all else, whether its information or prestige. Although he does have a sense of justice and doesn't hate humans as much as his followers, Ainz holds no deep attachment to them, and he feels nothing toward their deaths. After killing Shalltear with his own hands and then reviving her afterwards, he became a lot more vigilant and hostile against players or other foes with World Items that could possibly harm Nazarick in the near future.

On the other hand, Ainz has a competitive side to him, regarding the actions of players within the new world was what motivated him to not fall behind in terms of technological development. Likewise, everything he does was all for the sake of Ainz Ooal Gown, the Great Tomb of Nazarick, and the Sorcerer Kingdom altogether. For that reason, Ainz is secretive about the information he may have gain, refusing to disclose anything in case it serves Nazarick's interest. Since Ainz prioritizes knowledge as an utmost importance to him, he also likes to participate in doing random experiments. With the sole purpose of obtaining valuable information on the New World's inhabitants, martial arts, magic, items, or even their way of life such as religion.

In his dark warrior persona as Momon, he is a very dignified as a worthy adamantite adventurer yet he doesn't make others uncomfortable. He also very faithful, shown in the case that he refused Nfirea's request and to prioritize the Swords of Darkness. He also exchanged greetings with every single adventurer's group rather than meeting the princess (he send Nabe instead to prevent Gazef Stronoff from recognizing his voice), showing his caring nature and to sum up that he is as good as his strength.

Background
Before taking on the name of Ainz Ooal Gown in the new world, Momonga was his original name as a player in YGGDRASIL. While in reality, his real name is actually Suzuki Satoru.

When Suzuki Satoru first started playing YGGDRASIL under the name of Momonga, he was very close to quitting the game. This is because of being discriminated as a member of the Heteromorphic Races that Momonga is hunted down by PKers in groups. Therefore, Momonga himself was seen by other players as a monster who only exist to be killed. However, he was then saved by Touch Me, killing all of them at once with a surprise attack from behind.

Since then, both Momonga and Touch Me together made friends with seven others like them to form the First Nine, who started out the PVP/PKER clan, known as the Nine's Own Goal. After the dissolution of the clan Nine's Own Goal however, Momonga now becomes the guildmaster of an official guild called Ainz Ooal Gown upon Touch Me's recommendation, which everybody agreeably accepted. Momonga would later lead his guild and its members to victory in conquering the dungeon Great Tomb of Nazarick afterwards. It would later serves to be Ainz Ooal Gown's future guild base while dealing with the invasion of players intruding on their location.

Henceforth, the other players started to perceive the guild of heteromorphic races as evil beings. This way, the guild members of Ainz Ooal Gown including Momonga thought that it was only proper for them to become real monsters. Although Momonga was in the position of a guildmaster of Ainz Ooal Gown, what he actually did was miscellaneous work like contacting people.

Since Momonga doesn't have any real family or friends to support him outside the game, he dedicated his whole life instead to the game itself being YGGDRASIL and just his guild alone. Memories of the time he spent with his friends or guild members in Ainz Ooal Gown were all he had. Momonga's daily livelihood to the game has even go so far to the extent, where he used up most of the money financially obtain by him as a salary man in order to spend time playing it. In other words, Momonga has spent almost one-third of his monthly salary on cash purchases.

Even though all the other members had left, he still continue to stayed behind and kept the guild's base called the Great Tomb of Nazarick up and running. This was so in the hopes that his guild members would one day return back to the game and played with him. Even until arriving to the New World, Momonga would continued to reminisce about the past journey he has with his fellow guild members back then in YGGDRASIL.

The Undead King Arc
Momonga, the guildmaster of Ainz Ooal Gown, was seen conversing together with Herohero during the last moments of YGGDRASIL before shutdown. Herohero would then bid farewell to Momonga and logs out for one and only last time as he has already quit the game. Mentally, 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.

Momonga encounters Sebas and Pleiades at the Royal Suite and calls for them to accompany him. At the throne room, he discovers Albedo holding World 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.

Momonga using Mirror of Remote Viewing discovers a village being attack by knights. At first he doesn't want to get involved but reminiscence about Touch Me, who saved his life and decided to saves the village.

He realizes that Gazef is their target and he gives him a sculpture for good luck on his battle. He then switch with Gazef and faces the Sunlight Scripture led by Nigun Grid Luin, and offers them to surrender with their life or face death. He uses Negative Burst on the Archangel Flame, then uses Hell Flame on the Principality Observation and finally uses his Black Hole on finishing off the Dominion Authority. He easily defeats the Sunlight Scripture and went back to Carne Village to check Gazef's condition before leaving the village.

After the talks were concluded, Ainz gathered the Guardians in his room. Ainz explains to the Guardians it is only to require just cause and to avoid creating many enemies against them. He also explains to the Guardians that turning countries into graveyards will only damage the name of Ainz Ooal Gown.

Afterwards, Ainz's army are teleported via Gate and he introduces his army to them which made everyone realize that the small army of five hundred is not to be underestimated.

In the Katze Plains, the Imperial Army started to separate into two flanks, effectively opening a path for the army of Ainz Ooal Gown.

Ainz surveying the area that there is no player in the Kingdom or no one is trying to stop him, Ainz cast the Iä Shub-Niggurath, consuming the left wing of the Royal Army and summoned five Dark Young. Ainz was overjoyed that he breaks a new record for summoning five Dark Young and ordered them to massacre the Kingdom's Army.

One of the Dark Young was returning to Ainz and headed toward the Imperial Army's direction, which caused every single one of the imperial soldiers to run for their lives, trampling over their own allies.

Ainz stops Albedo and tells her that Momon will serve him as the sword of the Sorcerer King, which Momon accepts his offer. Afterwards, E-Rantel became a peaceful city without bloodshed under the rule of Ainz Ooal Gown.

The Ruler of Conspiracy Arc
Once the war was over and E-Rantel came under the rule of the Sorcerer Kingdom, Ainz has established the city to become the new capital of his nation. Under his rule, he has to decide on how to procede from their in ruling his nation by implementing new laws, set up defenses, establishing a new governing body, all of which was a lot more than he could handle. In addition, he moved to the former Mayor's residence and set it up as his base of operations.

It was also around this time he took notice of the severe anxiety of the people of coming under the rule of an undead and with all the monstrous beasts that were coming into the city. He also noticed the sever absenteeism of adventurers having new quests or anything to do as his minions have mostly taken care of all the problems that the adventurer's used to take. Ainz came up with the idea to change the Adventurer's Guild main goal from being a mainly monster hunting group into real adventurers that would explore the unknown. He met with the city's guild leader to discuss about it, intriguing him with this new proposition. Ainz would make suggestions such as providing the support and training through Mare's new underground training labyrinth constructed to train new recruits.

However, he has to make his goals known to all adventurers who would come to his kingdom. In order to attract potential new recruits, he decided to head to the Baharuth Empire to spread the word and to obtain some new supplies for his newly-formed organization. Just before he left, he also sent Albedo on a mission to act as an official delegate to the Re-Estize Kingdom to start official ties between the two nations.

He asked Guild Master Ainzach to accompany him to act as both a guide and adviser, recommending Ainz to see Osk who was known as the best weapons merchant in the empire. When he set up the meeting, the two talked a little about each other and start official trade relationship. While at the same time, both men soon came to have a mutual respect with each other. It was to the point, where Ainz even allows Osk to see his undead face and was one of the few humans who did not bear any ill will towards his undead appearance. Along the way, Ainz became interested about a dwarven sword that Osk has in his collection and was particularly curious about the rune inscriptions on it, which bore a striking similarity to his own world.

They also talked about the Martial Lord of the Empire's Gladiator Arena, where Ainz wanted to participate in a battle against him. Since Osk was the current champion's main sponsor and was a fan of strong warriors, he thought it would be interesting to see the fight happen, so he set up a match between the two.

At the Arena, he met face to face with Go Gin and at that moment, the two complimented each other out of mutual respect. Before the fight begins, Ainz turned off his High tier physical damage nullification effect to fight on more equal grounds against the Martial Lord. They also made a deal that if Ainz were to win, Go Gin would become a part of his nation to help trained his new adventurers while if Go Gin were to win, he would eat him, believing he can become more powerful by doing so. After sparring with each other, Ainz finishes the warrior off by striking him with one of the stilettos charged with Fluder's magic and killed him. Afterwards, he began to revive the Martial Lord, proclaiming his intentions to the people in the arena for all to hear publicly.

He came back to E-Rantel, satisfied with his accomplishments and at the same time was confused with Emperor Jircniv's sudden declaration of wanting his empire to become his vassal state. On the other hand, Ainz was more interested in the rune-mark weapon he saw, inciting him to make plans to visit the dwarves and its nation first while leaving the details of the vassalization to Albedo and Demiruge.

The Craftsman of Dwarf Arc
Not long after he came back from his business back in the Empire, Ainz has went and visit the Dwarven Kingdom in order to try to establish official relations with them through trades. More specifically with the objective to understand the runes they crafted into their items and weather if there was a possibility that another player had something to do with them.

It was also around this time that Cocytus has send one of the lizardman to hand his report in. He took the opportunity to ask the lizardman about information on the Dwarves in which he told Ainz that he does not know much other than there was someone from their tribe who had been to their nation before. The lizardman thinks Zenberu would be the best candidate to ask any information on them for that matter regarding the dwarves. After the talk, he also contacted both Fluder and Ainzach for any more information available. Unfortunately, they happen to know very little about it, so Ainz decided he should head to the lizardman village himself to ask for the information directly.

 * (To Albedo about Humans): "Well, upon meeting the humans here, I could only muster enough empathy to treat them as insects, but after conversing with them, I’m starting to see them as small animals."
 * (To Nigun): "The deal that I mentioned before is that I hope that you would quietly surrender your lives, this way you can be spared from physical pain. Otherwise, if you resist, which would be very stupid of you would have to pay the cost of dying in despair and misery."
 * (To his Guild Members): "My friends, what do you think about me hogging this glorious name? Will you be happy? Or displeased? Tell me if you have any feedback, tell me this name isn’t mine alone. I will change back and use Momonga without hesitation."
 * (To Albedo about Shalltear): "I am the one known as the Guildmaster of Ainz Ooal Gown. When engaging in PVP, the actual chance of victory is high, invincible against even those with flawless builds. How can I lose to the type of person who solely relies on their attribute. Furthermore, the most important fact is the strong bond I have with Peroroncino. Know that this battle was over even before it had begun Shalltear."
 * (To the Unknown Enemies) “I will definitely make you deeply regret your own foolishness. Do not think you can get away so easily when you anger us, Ainz Ooal Gown.”
 * (To Himself): "I am Ainz Ooal Gown. With that name at stake, there can be no defeat."
 * (To Shalltear): "Realize now, Shalltear. You face Ainz Ooal Gown, with the combined might of all Forty-One Supreme Beings from the beginning, you had no chance of victory."
