Muzan's menacing and cold-blooded disposition. Muzan is cold-hearted, ruthless, intimidating, and exceptionally intelligent. He sees no value in any humans he has encountered and shows little value in his own subordinates. He also has the ability to inject his victims with blood that allows him to convert them into more Demons. His final form however is purely combative. In his final or combat form, he has a red mace covering his body, particularly his arms, legs, and chest.
