Appearance

Ainz's true body is a fleshless skeleton with crimson-black flames in his eye sockets and a black halo behind his skull. During the final moments of YGGDRASIL, he wears a black academic robe trimmed in gold and purple. 589

• True form — Skeletal head, hollow eye sockets, black halo, and an ornate black robe. 589
• Momon guise — Jet-black full plate armor, a mask or helmet, and two greatswords carried on his back. 700
• Disguised face — When he removes Momon's helmet, he presents the face of an ordinary middle-aged man. 701

Personality

Ainz is intensely cautious around unknown powers, especially any sign of other Players. His first priorities in the New World are evaluating local strength, gathering credible intelligence, and ensuring Nazarick's security. 591 601

He carefully maintains the image expected of a Supreme Being. He privately rehearses expressions, gestures, and lines so that he appears suitably commanding before rulers and subordinates. 695 This concern for appearances often coexists with genuine care for Nazarick's residents: after losing Shalltear and Mare in battle, he feels guilt, resurrects Mare, and compensates the Guardians with resurrection rings. 637

History

At the shutdown of YGGDRASIL, Momonga remains in the Great Tomb of Nazarick and renames himself Ainz Ooal Gown. Nazarick's NPCs immediately affirm him as their Supreme Being and pledge their lives to his service. 590

After arriving in the New World, Ainz adopts the identity of the armored adventurer Momon. Accompanied by Narberal, he investigates the quality of local potions, seeks information about the world and possible Players, and works to establish a credible adventurer reputation. 590 591 Aura subsequently arranges a staged monster incident at Carne Stronghold, allowing Momon to defeat the Taurus Dragonoid publicly and rapidly gain renown. 592 601

Reports of persistent angels and a powerful force in the Abelion Hills convince Nazarick that another Player faction may be active. Ainz responds with increased caution, questioning Demiurge's contact with the region while ordering further investigation rather than openly committing Nazarick to conflict. 601 602

During the conflict involving the Deep Darkness Dragon Lord and allied Dragon Lords, Shalltear is killed and Mare is placed in grave danger. Ainz balances his desire to rescue his Guardians against the need to prevent further intelligence leaks, then resurrects Mare and reframes the battle as a strategic loss to conceal Nazarick's true strength. 629 637
