Go Gin

Go Gin is a war troll and the 8th Generation Martial Lord (also known as the Warrior King), serving as the undefeated champion of the Baharuth Empire's Imperial Arena in the anime Overlord (Season 4).

Unlike typical trolls, he's unusually intelligent, rational, and honorable, with sharp, prideful eyes reminiscent of Gazef Stronoff; he wears heavy full plate armor and wields a massive metal club, excelling in martial arts like [Divine Skill: Single Flash] and rapid regeneration.

Driven to surpass his racial limits through worthy battles, he duels Sorcerer King Ainz Ooal Gown in the arena, fights fiercely with mutual respect, loses decisively, and honorably pledges loyalty after Ainz resurrects him.
