Kyuku Zuzu

Kyuku Zuzu (キュクー・ズーズー) is one the five chieftains of the five lizardmen tribes, whom fought against the first undead army, and was amongst the few surviving lizardmen whom fought against Cocytus himself.

Appearance
He wears a white armor that emits a soft magical gleam. He is equipped with one of the four treasures of the lizardmen, White Dragon Bone Armor that was made from the bones of the frost dragon and enchanted with magic.

Personality
Being the chieftain of Razor Tail, he originally must have been a very intelligent being. However, after equipping the White Dragon Bone, he reduced to speaking simple sentences as the White Dragon Bone converts intelligence into the hardening of the armor. In addition, most of the wielders of White Dragon Bone have became mentally disabled after wearing it, the current chieftain of Razor Tail must have an extremely high intelligence.

Background
It's unknown on how he became the chieftain, though it is said that the Razor Tail had never decided the position of chieftain through physical combat. It maybe because of his intelligence that he became chief of the tribe.

The Lizard Man Heroes Arc
Kyuku Zuzu suggested that the lizardmen should not fight a defensive stance because of their disadvantageous in terrain. During the battle, he stayed behind as a garrison alongside Shasryu Shasha and the Chief of the Small Fang. A day or two later, knowing that they have no chance to win but still deciding that they must at least challenge this Cocytus, the lizardmen picked out the fifty most elite warriors among the lizardmen and then went to fight against him. He was one of the few not affected by Cocytus' passive skill. He attacked Cocytus but was killed by the latter's God Slaying Emperor Blade and was cut in half alongside his armor.

The Craftsman of Dwarf Arc
Kyuku Zuzu is later revealed to be one of the lizardmen that were resurrected by Ainz. He delivered a message from his liege, Cocytus to his master, Ainz Ooal Gown in E-Rantel. Ainz welcomed the former chieftain and questioned him about Zaryusu Shasha and his knowledge on the dwarves of the Azerlisia Mountains. He reported that Zaryusu was doing well but sadly has very little experience with the dwarves and suggested that Ainz speak with Zenberu Gugu.

Abilities and Powers
He is one of the user of the four treasures of the lizardmen, White Dragon Bone, which sacrifices the intelligence of the user in exchange for power. It would turn harder than steel, matching a mythril adventurer or even the legendary adamantite adventurer. His armor is strong enough to deflect all the weapons of the lizardmen.
