- "Roar, my secret arcana! Descend, o ultimate disaster! Flow, ye tears of despair and regret! — [Grand Catastrophe]!"
- - Ulbert casting his magic.
Ulbert Alain Odle's game avatar resembles that of a humanoid gray goat, crowned with a pair of wickedly curved golden horns. He is dressed in a black suit and velvet cape, with a rose pinned on his left shoulder. Upon his head is a beau and the right side of his face is covered with a golden mask.
Among all of the guild members, Ulbert Alain Odle was a person who was fixated on the word "evil" the most, since he suffered from Chuunibyou.
Additionally, Ulbert usually argued with Touch Me, mostly due to their competitive streak. However, Momonga thinks of their arguments as a pleasant memory, and believes they were still good friends with each other regardless.
On the other hand, he also tends to show his sincerity out of good will for his friend, Momonga while at times, act mischievous about it.
At some point in time, Ulbert joined the Nine's Own Goal and became quite close to Momonga and another one of the founding members. However, due to a disagreement that Touch Me had with the other founding member, it caused the unnamed friend of Ulbert to quit the game. This would lead to Ulbert developing some sort of grudge towards Touch Me as shown when the warrior disbanded the clan and he reacted negatively about it. To clear up the misunderstanding, Momonga wanted to let Touch Me speak. Hence, Touch Me was planning to turn the clan into a guild while nominating Momonga as the new leader which everyone including Ulbert agreed to his idea.
After forming the guild, Ulbert and his guild members began making preparations for invading the Great Tomb of Nazarick. He ends up being chosen to take part in Momonga's team to work with, taking on the role of a Magic Attacker. While making their way through Nazarick, Ulbert and Momonga would have a heart-to-heart talk where both would reveal the tragedy of losing their parents during their childhood. At the end of their conversation, Ulbert made a promise with his friend that he will do his best not to throw a tantrum again like last time.
Ulbert Alain Odle grew up in a poor family. Both his parents worked on the production line, but they died due to a work related incident and the insurance paid poorly. The incident is likely the cause of Ulbert's misanthropy, which flows into the character he plays as in YGGDRASIL. Like his friend Momonga, he only made it through graduating elementary school for education. During his time in YGGDRASIL, Ulbert killed a previous player who wielded "World Disaster" as the requirement for taking levels in this job class.
Upon conquering the Nazarick alongside his guild members of Ainz Ooal Gown, he created and designed a dominion on the 7th Floor. Additionally, Ulbert does the same in also designing the creation of Demiurge and choosing his Custom NPC govern the 7th Floor he made.
While playing YGGDRASIL, Ulbert was obsessed with a certain World Item that could summon an endless army of Demons that could overrun the world. Intrigued by that World Item, he attempted to build an item of his kind to emulate it and successfully created one to some degree.
Initially, a prototype was made with only three arms. Embarrassed by the creation, he wanted to throw it away. However, Momonga felt that it would be a waste and kept Ulbert's item. At last, the final product ends up being a demon statue with six arms and is in the hands of Demiurge.

When Ainz's summoned Death Knight pay a visit to Demiurge's domain on 7th Floor, the Floor Guardian noted that this land was made by his creator Ulbert. He went on saying that there were many things found hidden within it. He believed that these tumbled ruins are the true expression of Ulbert's love for it.
Once the Death Knight report back to Ainz about Demiurge's answer, Ainz pictured the thought that the relationship between Ulbert and Touch Me in the past was exactly how it was to Demiurge and Sebas to this day. Ainz has also took out a picture of thirty heteromorphic beings from his pocket space and point his finger at Ulbert and Touch Me standing next to each other as shown in that photo.
In the end, Ainz concluded that these two are never really able to get along well with one another even before the formation of Ainz Ooal Gown. Outside of these group photos he look over, Ainz stated that Ulbert and Touch Me would almost never be seen present in the same picture together.

During the meeting with Ainz alongside his fellow Floor Guardians, Demiurge states the reason behind why he suggested the "Bathing Together" voucher was because of the wise words his creator Ulbert used to say.

When Ainz recognized that Demiurge was really into details while playing the game, he thought the same could also be said with his creator Ulbert but then went on to think, that everyone in the guild of Ainz Ooal Gown was like these two.

Ainz reminiscences about an argument that took place between Touch Me and Ulbert Alain Odle. He argued with Touch Me that there are people who need to kill the Ice Dragon to fulfill their class-up requirements. In the end, Ainz remembers using the majority vote rule for his guild to decide on whether they follow through with Ulbert's or Touch Me's plan. To decide on a majority vote, they used coins, the kind wherein which the new coin was supposed to represent Ulbert while as Touch Me represents the old coin. 
During the disturbance, Ainz remembers that Ulbert was obsessed with a certain World Item that could summon an endless army of demons that could overrun the world. He attempted to build an item to emulate it and successfully created one. Ulbert's prototype was left in the Re-Estize Kingdom as an explanation for the demon attack.
The Invaders of the Large Tomb Arc
- Main article: The Invaders of the Large Tomb Arc
When Ainz decides to give a reward to Sebas, he remembers that Demiurge suggested that Sebas and Tsuare forming a relationship would be a good thing. He wonders if Sebas and Demiurge actually have a good relationship and feel relieved that they aren't fighting anymore. He then makes a comparison between the two's relationship as similar to their creators, Touch Me and Ulbert.
During that moment, Ainz reminisces that the reason for the conflict between Touch Me and Ulbert was due to something outside of YGGDRASIL. Ulbert’s jealousy towards Touch Me was most likely due to real world reasons. Ainz remembers that the relationship between the two became tense ever since the quarrel they had one time and wonders if that was the cause of everything. Ainz then wonders for the last time thinking that if he was the person as of now, perhaps he could have understood the reason for his friends' quarrel back then.
The Ruler of Conspiracy Arc

After hearing Demiurge's myth, especially the part where Ainz save humanity then leave but will return one day, the Overlord ponders whether his subordinate had another plan in mind. Ainz thought that maybe what Demiurge wishes for the most was actually his own creator Ulbert to be the one to return rather than him.
The Paladin of the Holy Kingdom Arc
After destroying the Holy Kingdom's Great Wall and ordering his demi-human army to commence the invasion, Demiurge made sure his suit is clean from any dust that fell on him during the destruction. He considered his suit an important item given to him by his creator Ulbert. He smiled under his mask upon recalling the mighty being who created him.
During the meeting between two Floor Guardians and Ainz in a log cabin, Ulbert's name was suddenly brought up by Albedo after Demiurge chose to support his master's plan. Hearing Demiurge's answer, she inquires him whether or not he will still remain composed if it was his creator instead of Ainz who suggested such idea of faking his own death.
Abilities and Powers
Ulbert Alain Odle is the most powerful magic caster of Ainz Ooal Gown. He was equipped with the strongest magic caster class called the "World Disaster", a class with incredible firepower and destructive magic. On top of that, he took levels in several classes boasting high firepower which further specialized his offensive ability. As a result, his burst damage was unrivaled among the top two members of the guild.
By attack power alone, Ulbert was easily among the top five in the guild, but he had a weakness. Though he had an ample supply of MP, his consumption rate outstripped even that. In other words, he burned through MP rather quickly when using one of his potent spells. Upon mastering the power of "World Disaster" class, he has managed to gain a new spell known as "Grand Catastrophe" under his arsenal.
- Grand Catastrophe: As Ulbert's trump card, it is an ultimate move which requires 60% of his mana. Its destructive power outstripped the might of even super-tier spells. This spell is capable of wiping out four level 87 Primal Fire Elementals and the level 90 Primal Star Elemental summoned by Asura, which should have been at full health, were instantly annihilated.
- Magic Arrow
- Ring of Ainz Ooal Gown: It allows the user to freely teleport between every room inside Nazarick. Every member of Ainz Ooal Gown was required to wear this ring.
- Armageddon Evil: He once made this item out of admiration for an unknown World Item, which was capable of summoning an endless amount of powerful demons.
- Armageddon Evil (Prototype): A prototype of the item he made before handing it over to his friend, Momonga. In the New World, Momonga would later pass it down to Ulbert's NPC, Demiurge.
- Cash Items
- Unnamed Wand: He used one to cast his area-of-effect attack spells.
Ulbert is the creator of Demiurge, who is the embodiment of his fixation on the evil thematic.
Ulbert trusted him with final decisions without complaint. He even entrusted Momonga to keep his failed World Item prototype. Both him and Momonga were part of the No Cash Item Alliance. Ulbert was quite close to Momonga and even confided in him as he saw Momonga as a born-loser like himself. Both share similar tragedies when they were young, losing their loved ones to the grinding indifferent wheels of society.
Ulbert had conflicting issues with his guildmate, Touch Me, mostly due to their competitive streak, but also real life concerns. He disliked Touch Me but he knew it was just a pointless jealousy towards him because Touch Me was Ulbert's opposite. Ulbert's antagonist relationship with Touch Me was inherited by Demiurge, who also shares a strained relationship with Sebas Tian, Touch Me's creation.
He and Peroroncino were the first ones to came up with an idea of forming a No Cash Item Alliance with the idea that they could compensate for the weakness with skill.
They worked together in the same team to clear the Great Tomb of Nazarick. Ulbert trusted her skills as a player and would follow her instructions.
He happens to work well with Yamaiko as the two are willing to cooperate jointly on clearing the Great Tomb of Nazarick.
He and Warrior Takemikazuchi are working together with the rest of his party members to clear the Great Tomb of Nazarick.
He alongside Nishikienrai are in the same team to conquer the Great Tomb of Nazarick.
- Ulbert is one of the guild members, who suggested on conquering the world as a joke.
- During the last moments of YGGDRASIL, Ulbert confronted someone in the real world.
- Before the formation of the Ainz Ooal Gown, Ulbert is considered to have the highest firepower in the clan called Nine's Own Goal.
- Let alone Momonga who could be considered a Chuunibyou as evident from his own creation of Pandora's Actor, Ulbert also do happens to be one too based on how the way he acts.
- Completely unlike his usual style, the preamble before the spell's name, [Grand Catastrophe] was different each time represents the naked expression of his soul.
- (To his Guild Members): "If they make it to this point, let's give the heroes a grand welcome. There's a lot of players saying we're evil and whatnot, so why not wait for them majestically inside like final bosses?"
- (To Touch Me): "It seems like Touch Me-sama is the one who doesn’t remember that there are people who need to kill the Ice Dragon to fulfill their class-up requirements."
- (To Yamaiko about Nazarick): "I agree as well. Being that the dungeon is dangerous, it will also offer a great reward when we complete it. I want to take advantage of our early discovery and attempt it by trial and error so we can gain the reward for clearing it. Unknown dungeons are troublesome. We should go gather information on how to beat it before other people find out about it."
- (To Momonga about Touch Me): "Momonga-san… You're right. I went too far. Still, don't you think he’s being selfish? First he chased that person away, and now this. If this is the case, shouldn't he have disbanded us earlier?"
- (To Momonga about him becoming Guild Master): "I don't think so. Personally, I feel Momonga-san is an excellent candidate. He logs in regularly, is meticulous, and he doesn’t have any strange habits. Also, he’s a neutral party who isn’t biased towards anyone."
- (To his Guild Members): "—Everyone, you're being too overconfident. Do you know how low the odds are of one-shotting an unknown dungeon? The effective level of a dungeon goes up several times when you try it for the first time."
- (To Momonga): “I've been thinking about it recently, but if damage is all you want, wouldn’t that be more easily done by the frontliners? Magic casters ought to know utility spells."
- (To Momonga): "Momonga-san, I'm really sorry for saying this, but aren't you a born loser like me, Momonga-san? No matter how hard you try, you'll never be able to lead a comfortable life."
- (To Momonga): "If they didn't teach you the bare minimum in elementary school, you couldn't even become a subordinate to the born winners, so they made elementary school easy… Honestly, it's ridiculous how you end up at one of two extremes in this world from birth. It's insane how unfair this world is. You can climb the ranks if you work hard? Don't make me laugh.”
- (To Momonga): "My parents died pretty horribly. Working in such a dangerous place… they couldn't even find their bones, you know. And the compensation they paid to their employees was miserable. That's why they didn’t stop the production lines. After all, stopping them would incur huge losses. Losers like us… they use us up and throw us away."
