A Necromancer challenging the War of the Corpses. Coming from the lowest social class, he grew up eating trash in junkyards and suffers from severe self-loathing. Even in his dreams, he suffers from nightmares where his father—a truly garbage human being—constantly tells him he will never be the best. Though he is handsome, his personality is not great. Having never made a single friend, his way of speaking is blunt and unfiltered.

Only one arm and one leg can be controlled by a Necromancer. She is the corpse Us uses to participate in the war. Unusually, while most corpses lack intelligence and only follow orders, she possesses her own intellect, and one arm and leg do not obey the Necromancer. Note that Necromancers do not control corpses through speech; they must possess the corpse and attempt to move every single muscle. There is a red heart in the middle of her chest; if it is pierced, she dies. When her hand glows red and burns, it becomes incredibly powerful, capable of piercing almost any defense regardless of strength—a one-hit kill. However, using it burns the hand, making it unusable for 4 hours, meaning it can only be used once per match.

An old man who has participated in the War of the Corpses for 30 years without ever making it past the preliminaries. No matter how angry he gets or if he is betrayed, he never blames others; if something goes wrong, he takes the blame himself. He controls a cockroach-shaped corpse and is quite skilled. He uses a skill called 'Extinction Dash,' but every time he uses it, the energy consumption is so severe that the corpse explodes. However, he believes that one day he will succeed if he trusts himself. He just wants to shine, even if only once. The cockroach-shaped corpse he controls is named Roach Knight.

Extremely fast and equipped with a sharp, sword-like protrusion on its head; if stabbed by it, the opponent can be caught in a combo. It can continue to move rapidly even if it loses its head or several legs. It seems capable of successfully performing the ultimate move 'Extinction Dash' with just a few more attempts, but it is uncertain if Bolak's mind can hold out until then.
