Meteoric Turtle

Meteoric Turtle was an NPC boss that existed in YGGDRASIL.

Background
Before Ainz Ooal Gown acquired the Great Tomb of Nazarick, they faced this boss called Meteoric Turtle and defeated it in battle.

Appearance
Presumably judging by Meteoric Turtle's name, it probably resembles an enormous turtle.

Abilities
The Meteoric Turtle had a move where it enhances its defense, then jumps to the sky before crashing down again like a meteor. Its signature attack is dealing a party-wiping amount of damage to everyone in an area. The countermeasures to this move are: make the boss lose its balance and forcibly break its defensive stance; take the fight to the sky and halve the damage taken; or to continuously use defensive spells or skills to endure the onslaught.

Trivia

 * In the fight to conquer the Great Tomb of Nazarick, Bukubukuchagama noted the final boss had similar abilities to Meteoric Turtle.
