Guu

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

Appearance
Goo is a gigantic, muscular troll.

Personality
Like other trolls, Goo is a violent, simple-minded monster with little intelligence. He regards 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 in order to gather forces strong enough to combat the ruler of the mysterious tomb that appeared in the southern area of the forest but his own arrogance proved to be his downfall as he was easily defeated by Ainz without any trouble and all of his territory afterward were given to Ryayus to control under Ainz direct rule.

Abilities and Powers
Owning similar strength with Hamsuke, it seems that Goo is also around level 30. He also owns 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 there continued loyalty.
