Momonga, also known as Ainz Ooal Gown, is the main protagonist of the popular anime and light novel series “Overlord”. He has a cautious and strategic personality, always planning and controlling details to avoid haphazard actions. He is known for his stinginess and tendency to overkill opponents, never underestimating them. After being transported to a new world and becoming a true undead, Momonga develops a cold and calculating demeanor and suppresses his emotions. Despite this, he remains loyal to his friends and creations, and acts with nobility and devotion to his followers in Nazarick, the Great Tomb of Nazarick, which he rules as Guild Master.


Momonga was originally a human player in the popular virtual reality game YGGDRASIL. As the guild master of Ainz Ooal Gown, Momonga led his guildmates and ruled over the Great Tomb of Nazarick, a massive dungeon filled with powerful monsters and treasures. But when the game’s servers were shut down, Momonga found himself trapped inside the game as his character, Ainz Ooal Gown. In this new world, Momonga takes the name Ainz Ooal Gown and becomes the ruler of Nazarick, using his vast knowledge and power to establish himself as the Wizard King of the Wizard Kingdom.


Momonga’s appearance is that of a powerful undead being. As Ainz Ooal Gown, he has a skeletal body with empty eye sockets and a dark, regal robe. He exudes an aura of authority and power, adding to his intimidating presence. In certain situations, Momonga assumes the alter ego of “Momon,” a dark warrior known as the leader of the Darkness, an elite group of adventurers in the New World. In this form, he hides his skeletal appearance with a fully armored robe, wields a greatsword, and wears a helmet that hides his face.


As Guild Master of the Ainz Ooal Gown and ruler of Nazarick, Momonga possesses immense power and a vast array of abilities. He is considered the most powerful sorcerer in the world and is feared by many as the Sorcerer King. Highly skilled in various forms of magic, Momonga possesses a wide range of spells that allow him to manipulate and control the elements, summon powerful creatures, and even alter reality itself. His mastery of necromancy and death magic is particularly noteworthy, as he can raise the dead and create powerful undead minions to serve him.


Momonga originated in the virtual reality game YGGDRASIL, where he was once a human player. He ruled the guild Ainz Ooal Gown and led his guildmates in the conquest of the Great Tomb of Nazarick. But when the game unexpectedly became his new reality, Momonga found himself transformed into his in-game character, Ainz Ooal Gown, and trapped in a world populated by sentient NPCs. From this point on, Momonga’s journey begins as he navigates this new world, using his knowledge, power, and strategic mind to establish his dominance and protect his newfound home, Nazarick.
