Guu

Goo (グ) was a giant troll who ruled the Eastern Tob Forest.

Appearance
Goo was a gigantic, muscular troll.

Personality
Like other trolls, Goo was a violent, simple-minded monster with little intelligence. He regarded long names are only for the weak, which made him to ignore Ainz Ooal Gown.

Background
Among the diverse variety of Trolls, Goo can be classified as 'War Troll', a very special mutant adapted to battle itself. This made him as the ruler of the Eastern Forest, with numerous monsters under his command.

The Two Leaders Arc
Goo and Ryrayus formed an uneasy alliance together, after the disappearance of the Beast of the South and the appearance of Nazarick in the southern forest. They forcibly recruited the inhabitants of forest in order to gather forces strong enough to combat the ruler of the mysterious tomb.

When Ainz confonted the two rulers of the Tob Forest, Goo believed the undead to be weak and challenged him to a duel. But his own arrogance proved to be his downfall as he was easily defeated by Ainz without any trouble and his territory was given to Ryraryus under Ainz's direct rule.

Once Goo was dead, Ainz resurrected him as an undead troll. Since his corpse was seemingly undamaged, he did not look like he was an undead being and used him along with several other creatures to organize an attack on Carne Village. This orchestrated attack was to test the village's defenses as well as their loyalty.

He met his second end facing Jugem who slashed him and claimed his sword as his own.

Abilities and Powers
Owning similar strength with Hamsuke, it seems that Goo was also around level 30. He also owned a magical great sword with poisonous effect.

Trivia

 * His sword was given to the people of Carne Village after he was slain as a gift from Ainz for their continued loyalty. Currently Jugem is the new owner.
