Zero

Zero (ゼロ) is the leader of the Six Arms and the head of the security department of the criminal organization Eight Fingers.

Appearance
Zero is a bald giant man with half of his face and body covered in tattoos of various beasts. Everything about him is large and the outlines of his muscular figure can be seen even through his clothes. The cold glint in his eyes belonged to that of a seasoned warrior.

Personality
He is a strategic thinker and always composed, and examines any situation calmly. Given his experience, he was observant enough to recognize that the hole made by Sebas on the iron door of the brothel he entered was made by a fist, not a magical item.

The Men in the Kingdom Arc
Zero, along with the executives of Eight Fingers, meet in an undisclosed location to discuss various issues affecting the organization. Zero offers to assist Hilma with his resources, but was turned down. However, one of the executives, Cocco Doll, requested for his security services in order to reinforce his hold over his declining slave trade division.

After learning that the brothel had been seized, and that Succulent and Cocco Doll were captured by the authorities, he orders Six Arms to bail them out, as well as gather information on those who were responsible for the attack on the organization and punish them in return.

When Sebas Tian is told to come to a warehouse alone due to Tsuare's kidnapping, four of the Six Arms were there waiting for him. They engaged him in combat but failed to even scratch Sebas and are killed. The other two were waiting elsewhere and encounter Brain Unglaus, Climb and Lockmyer. Succulent had disguised as Tsuare in an attempt to get them to let down their guard but fails and is defeated by Climb and Lockmyer. Zero and Brain engage in a fierce battle but are interrupted by Sebas. Not believing that Sebas could kill four of the Six Arms by himself, he puts his duel with Brain on hold and attacks Sebas with his strongest attack. It however, does nothing to the butler and Zero is killed with a powerful heel drop kick.
