Momonga's Red Orb

Momonga's Red Orb is the tentative name for one of the World Items under the possession of Ainz Ooal Gown. It is the World Item Momonga has primarily equipped within his belly at all times in the New World.

Description
In the Web Novel, when the Great Tomb of Nazarick was once invaded by players of YGGDRASIL, Ainz noted that half of the invaders from the last war fell victim to this World Item and died in combat because of it.

According to the author Maruyama, Momonga's name is attached to that World Item. The author went as far as to state that it is a top-notch “SECRET-OF-Momonga” which nobody but him alone should be able to know about. No matter who got a hold of this World Item, the name cannot be changed as it belongs to Momonga.

Appearance
It takes on the shape of a reddish glowing orb. In the Light Novel, this red orb was said to exude an aura of dread from how the workers of Foresight viewed it.

Abilities
The World Item Ainz possesses is very versatile, having many different powers to choose from and use. For example, one of these powers is very effective against Dragons.

Only in the Web Novel, Ainz notes that the red orb is a World Item that becomes more powerful as long as he continues wielding it. Although Roberdyck used his fists to hit the red orb, which he believed to be Ainz's supposed weakness, the hardness of this World Item was strong enough to easily withstand a blow from the Worker's attack. It was to the point that his fists were repelled by the World Item's hardness, leaving an astounding recoil on the Worker's gauntlet-like weapon, and the gauntlet completely broke apart during the process.

From the Web Novel, Ainz’s World Item could use enough experience points to make him lose five levels if ever used.

Trivia

 * Based on Ainz's description about the World Item in the Web Novel, the fact that it can get stronger is a bit similar to that of another World Item known as World Savior.
 * During the guild of Ainz Ooal Gown's first conquest of the mysterious tomb, Momonga never seemed to have this Red Orb equipped on him during that time.
