Gender: Male Height: 185cm Age: Unknown. Appearance: A lean, gaunt physique. Wine-colored skin. His eyes appear devoid of emotion. Characteristics: One of the Duelists. He has no moral compass and is closer to a bloodthirsty mad dog. He exhibits random emotions—sometimes laughing loudly, sometimes chuckling low, and sometimes letting out screams that are hard to frame in human language. He loves to smile, so he is always wearing a grotesque grin. He kills and eats humans to satisfy his impulses and hunger; if his hunger persists for a long time, he becomes excited, aggressive, and even more dangerous. The blood in his body is acidic. He employs patternless actions, making him completely unpredictable. He resides in a cave where a red light leaks out. He makes those who see him feel psychological pressure. His blood is a deep pink color and slightly viscous. •Abilities• [Acidic Blood/Fluid Manipulation and Control] He can control detached blood, body tissue, or blood drawn from his own body using his mind. His blood contains a hallucinogenic component called LSD; if the blood contacts or enters an opponent's body, it causes hallucinations. He can use this to create small clones, which are sometimes fickle but generally follow orders. -Acidic Blood Clones- •Puppet •Bloody Bug •Head Buster [Extreme Physical Regeneration] His regenerative powers are bizarrely superior, to the point of reattaching limbs or transforming body parts (stretching arms, creating a body like a human centipede, etc.). [Magic and Spells] He rarely uses them. [Flame of Negation] He generates and detonates dark red flames, which temporarily seal any ability of an opponent hit by them. □Berserk Mode□ When hunger persists for a long time, he goes berserk, increasing blood circulation to extremely enhance his physical abilities. When berserk, eyes form above his eyebrows, totaling four. •Weaknesses• Certain levels of magic, fire (most fatal), blunt weapons, the brain. Trivia: When not hungry, he just lies around lazily. Because he only smiles, he doesn't talk much, and when he does, he mostly speaks in short words (e.g., Hate it, No?, You can't leave, Hungry, Hehehe...). If he is decapitated by an opponent rather than by his own will, regeneration takes a long time. It is unknown if he has internal organs, but he probably does.

Bog's most basic acidic blood clone. It looks exactly like Bog and exhibits random emotions like its master, but has no special abilities. Bog can use this to transfer his consciousness and switch his main body.

A slime about knee-high. Made of flesh, it is wine-colored with round pink eyes, and is surprisingly cute (though the sounds it makes are terrifying). When summoned, it always follows Bog and acts as a support (transforming into projectiles or thorns, exploding like a fountain, being used as a regeneration tool for Bog, etc.). Sometimes, they take the form of spheres made of Bog's flesh (palm-sized) and fly at the opponent in groups to explode.

Looks exactly like Bog but has no facial features and is thinner. Even without orders, it walks slowly toward the target and detonates its own head to spray acidic blood.
