Asura is the tentative name for the Raid Boss that governed the Tombstone floor of the Great Tomb of Nazarick and fought with Ainz Ooal Gown during their raid to conquer the dungeon.

Appearance
The boss resembled a wrathful Nio statue of the fallen divinity "Asura". It stood five meters tall, with six arms, and his body is covered by an exquisite armor. On every one of his arms, he held a different weapon: a sword, an axe, a spear, a club and bow & arrow on the last two.

Background
Asura was one of the five rulers of the Great Tomb of Nazarick that Ainz Ooal Gown had to beat in order to acquire control of the base dungeon. According to the Lord of Helheim's speech, he along with the other bosses are only released when players challenged them, with everyone of them becoming stronger by the order of their release.
