モモンガ, Ainz Ooal Gown, Dark Warrior Momon, Great One, The One, Supreme Being, Raven Black Hero, Demon God, Great Sorcerer King, Undead King
He is the guild master of Ainz Ooal Gown and regarded as the highest of the Almighty 41 Supreme Beings by the NPCs of the Great Tomb of Nazarick. He is also the creator of Pandoras Actor. A cautious and stingy person Momonga always tries to plan and control details avoiding any haphazard actions. Because he doesnt underestimate his opponents he will usually overkill them. Since being transferred to a new world and becoming an actual Undead being Momonga 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. Momonga only does things that will benefit Nazarick or himself whether its information or prestige. Although he does have a sense of justice and doesnt hate humans as much as his followers he holds no attachment to them and he feels nothing toward their deaths. Source: Overlord Wikia
