MUZAN KIBUTSUJI

Muzan

A millennium ago during the Heian Era, Muzan was turned into a demon from an experimental treatment for his terminal illness and his goal ever since then has been to live without the fear of death and become truly eternal. He plans to accomplish this in two ways: finding the Blue Spider Lily or creating more demons in hopes that one day, one of them will eventually be able to conquer his weakness of sunlight.

Appearance

Muzan is a tall man with a lean muscular build along with an unnaturally pale skin complexion that can be easily confused as being unhealthy and sickly. He has curly black hair and sharp, almond-shaped eyes. His irises are cat-like in appearance and are of a plum red color. He also possesses sharp, blue nails on his hands. Physically, he appears to be in his twenties. But this is just his appearance of choice. Muzan has the ability to shapeshift and has been seen as many things including a woman and a little boy.

Personality

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. Rarely ever visibly upset or happy, he appears completely monotone and detached on most occasions, even when he callously murders his own subordinates. The only times he ever shows emotion are when his vision of perfection is moving forward or when he has subordinates completely submit to his will. Initially, his expressions would only change slightly and only bear a slight shift from his usual calm attitude and his tone of voice tends to be consistent at nearly all times, accentuating his monotonous demeanor. His cruel and imposing nature has gained him the great admiration and fear of many demons.

The most prominent trait Muzan possesses is extreme narcissism, pettiness, and an obsession with becoming the perfect being. As he has had over a thousand years to live and observe, along with hardly any real challenges, his extreme egocentrism is almost expected. He considers almost nothing to be his concern except overcoming his inability to walk in the sun, which is his primary drive. His long life and obsessions have caused him to want every plan he concocts to be absolutely perfect, and his superiority complex prevents him from seeing his own failures. His belief that he is the closest thing to a perfect being causes him to have zero tolerance for any failure, brutally punishing those who fail him or those he considers weak, even if the failures are minor.

Abilities

Genius Intellect: Having lived for over a millennium and gained further experience from the telepathic link with the demons he controls, Muzan is extremely clever and erudite. Since he has five fully functioning brains, it would most likely boost his intelligence and other mental capabilities such as memory and cognitive processing. He was able to evade the Demon Slayer Corps for nearly a thousand years despite the leaders of the Corps, the Ubuyashiki Family possessing great foresight and intuition, and he has also used demons to create distractions somewhere far away when he wants to hide something from the Corps. Even as a recently transformed demon, he was skilled at reading the negative emotions of others and was able to manipulate his five wives into committing suicide.

Demon Abilities: Muzan has displayed the ability to absorb, assimilate and dissolve organic and inorganic objects. He can also drastically elongate both his arms, growing spiky red or white coverings around his extended limbs and shapeshifting his hands into bladed protrusions, which he swings like whips to slash apart his targets. Muzan's arm whips also possess numerous mouths full of sharp fangs all throughout them. Muzan mainly uses these mouths to inhale with immense suction strength, causing anyone near it to be sucked into its sharp jaws and be slashed apart.

Nigh-Absolute Regeneration: As the Demon King, Muzan possesses the fastest and most advanced regeneration out of all demons, recovering so fast that it appears as if the attacks phased through him, and he was never injured in the first place. He displayed his flawless regenerative ability on multiple occasions. Most prominently, Muzan has overcome the weakness of decapitation by Nichirin Swords, as shown when he completely regenerated his head moments after it was pulverized by Gyomei's spiked flail. After being caught in a huge explosion orchestrated by Kagaya Ubuyashiki, Muzan was able to instantly regenerate his body after having it been damaged extensively and also manages to circumvent the metal spikes added into the explosion meant to slow down his healing speed.

Demonic Blood: After the experimental treatment gave him a new body and physiology, Muzan's blood develops special mutagenic properties that can transform humans into creatures known as demons. His special blood also seems to give rise to a plethora of special abilities to those that assimilated his blood such as powerful and quick regeneration, the power to control their flesh, immortality, an accelerated growth rate, enhanced physical prowess and even supernatural abilities called Blood Demon Arts.

Muzan can also further empower a demon by giving more of his blood, enhancing their pre-existing abilities. However, this is limited to how much blood the recipient can withstand and adapt to. If a human were to take in too much blood from Muzan, their body would mutate faster than they can withstand, causing them to self-destruct into one giant mass of flesh before disintegrating into ash. The same would also presumably happen to a demon if they couldn't withstand the blood's effects, as implied by Muzan.

Fighting Style

Despite not being trained in combat like most members from the Twelve Kizuki, Muzan is nonetheless proficient in battle, having fought countless Demon Slayers over his thousand-year long existence. When fighting, Muzan utilizes bladed and flexible whips as his main form of attack. However, instead of using his flesh to form a weapon, Muzan instead contorts his own body to project said whips, giving him the added advantage of manipulating its shape and controlling the trajectory of his whips at will. He contorts his arms into whips and uses it strike his targets from afar while he remains stationary.
