Muzan Kibutsuji is the main antagonist of Demon Slayer: Kimetsu no Yaiba. He is the first demon, the Demon King and the leader of the Twelve Kizuki, a group of the strongest demons in existence.
A millennium ago, during the Heian Era, he was turned into a demon through an experimental treatment for his terminal illness. Since then, his goal has been to become truly eternal, either by finding the Blue Spider Lily or creating more demons.
We plan on adding more information about Muzan Kibutsuji, but for now, enjoy the brief overview of this powerful Demon Slayer villain…
As the Demon King, he can control all demons who have assimilated his blood, except for Nezuko Kamado, Tamayo, Yushiro and Chachamaru. He is also revealed to be of the same bloodline as the Ubuyashiki Family.
Muzan has an unnaturally pale complexion, curly black hair, sharp, almond-shaped eyes and sharp, blue nails. He is tall and muscular, and has appeared in various disguises throughout the series, including an elegant woman and a young child.
After neutralizing Tamayo’s poison, his hair turns white and he grows numerous mouths all over his limbs.
In his final form, he adopts an enlarged demonic baby form to slow down the effects of the sun. He is covered in pronounced blood vessels and has small claws and fanged teeth.
Muzan is Cold and Intelligent
Muzan is a cold, ruthless, and intelligent character who values humans little and shows little concern for his own subordinates. He is often stoic, with a monotone demeanor, and expresses emotion only when his vision of perfection is moving forward or when he has subordinates completely submit to his will. He is highly admired and feared by other demons for his imposing nature. He has an inflated ego and believes that others exist only to serve him, and he rarely takes any opponent or threat seriously.
The video below highlights the first two moments where we get a good look at Muzan in the anime series, and as you can see, this demon has no regard for human life and is incredibly powerful.
