As the Demon King, Muzan can control all those who have assimilated his blood to become demons, with Nezuko Kamado, Tamayo, Yushiro, and Chachamaru being the only exceptions.[13] A millennium ago, during the Heian Era, Muzan was turned into a demon during an experimental treatment trying to cure his terminal illness,[1] and his goal since then was to live without the fear of death and become truly eternal.[10] He plans to accomplish this in two ways: finding the Blue Spider Lily or creating more demons in hopes that one day one would be able to conquer their weakness of sunlight.[11][12] Muzan is a tall and muscular man, 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 colored plum red. He also possesses sharp, blue nails on his hands. He appears to be in his twenties.

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 visually 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. The manga shows him to be more expressive, particularly when enraged and his facial features are exaggerated to demonstrate as such (possibly as a way to display his normally unreadable emotions). In the anime, his expressions change slightly 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. His inflated ego and delusional sense of self worth are so large that he cannot stand being mocked or corrected in any fashion, believing that others only exist to serve him. It also means he rarely ever takes any opponent or threat seriously. He brutally killed a drunk man simply for being rude to him, and killed the man's brother and a female companion when they had done nothing, all while proclaiming his own perfection and superiority over them, displaying his pettiness as he won't settle for any mockery and will do anything he pleases until the humiliation is remedied. This event also hints that Muzan has unpleasant memories of his weaker, human past, and is very self-conscious of his unnaturally sickly appearance, immediately following with a lengthy denial that he is unhealthy, sick and much less on the verge of death, in all likelihood a bitter reminder that he is still imperfect. When he confronts Kagaya Ubuyashiki, the man responded to Muzan in a tone of pity and sadness for the life he had led. However, Muzan only interpreted it as insults and threats, which further accentuates his hatred for humanity and the Demon Slayers. He also believes that Heaven has let him off the hook for murdering thousands as he has never seen a God or Buddha. The most prominent trait Muzan possesses is extreme narcissism, pettiness and an obsession with becoming the perfect being. As he has had over 1000 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 god 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. Furthermore, his delusional sense of omnipotence is such that he compares himself to natural disasters, namely something that is far beyond what humans can compare to and fight against. As a result of this, he believes the Demon Slayers to be a group of deviants who cannot accept the natural order of things and resume their lives as normal when other people simply move ahead following a tragedy. His analogy evidences his complete inability to feel sympathy or remorse for his actions, given none of the murders he ever committed (directly or indirectly) were the result of an accident but carefully orchestrated acts of pure evil. Being the obsessive perfectionist he is, Muzan loathes the very concept of change; be it change of circumstances, physical, emotional or change of any kind. He equates change to decay, and thus evidence of imperfection. In his own words, he loves things that remain unchanging, constant and in a state of permanence. At the same time he views one's own humanity as a sign of weakness, believing Gyutaro had lost because he was still attached to his sister Daki, even deriding the Upper Moons, stating they were now ranked in order of how much humanity they had left. Gyutaro's defeat at the hand of the Demon Slayers deeply angered Muzan, as they had undone a status quo that lasted for 113 years, causing him to lash and demand more self-sacrifice out of the remaining Upper Moons. This could also help explain his brutal execution of the Lower Moons as their membership was in a constant state of change, and he grew tired of managing them. Behind the myriad of façades Muzan displays, and completely offsetting his insatiable ego and lust for perfection, Muzan is unbelievably cowardly. He always avoids conflict whenever possible as evident in his encounter with Giyu Tomioka and Tanjiro Kamado. He has shown to be very manipulative and cunning, being able to blend in human society normally, even having a family of his own to add. A long life and continued practice has allowed him to take on many roles in society and play them capably, including children and women should he choose to. This life has also given him great intelligence and ability to think tactically. Muzan is a quick-thinker and strategist who is able to deal with unfavorable situations rapidly and quite well, though this may also be because the loss of his subordinates means nothing to him in the long run.

Muzan not willing to let Akaza die Muzan manipulating Akaza to continue fighting. Because of his perceived superiority and his double-faced nature, he feels little attachment to his henchmen, using them and discarding them as disposable pawns whenever he sees fit. He does not allow his subordinates to question him, regularly enacting brutal and ruthless punishments should they do so. Many of his subordinates, in turn, are deeply afraid of him, and measure their words and thoughts carefully for fear of saying anything to displease him. He is able to sway many demons to his side with promises of power, revenge, and grandeur so long as they serve him. His intelligence and manipulation shine here, since many find the promises appealing, as he encounters many of his subordinates at their lowest point, when their emotions are easy fodder for him. Alas, all of these promises are ultimately false, given that Muzan only cares about himself and has no qualms about killing his own subordinates to protect his own safety.

When not hiding behind a façade, his sheer malice and overflowing violent intent are so incredibly malignant, they can be perceived by others. Most notably, Yoriichi Tsugikuni described him as being like boiling magma erupting from a volcano, ready to consume everything. In the anime, the extent of his rage is visible during the Upper Moon meeting, where the many glasses and flasks he was working with, all broke apart and exploded in thousands of pieces in reaction to Muzan's boiling frustration over being unable to achieve his goals, his fury greatly intimidating the Upper Moons.

Beyond his egocentric demeanor lies a sense of self-preservation that easily overrides his megalomania, most notably shown by his act of cursing his subordinates in a terrifying manner so that none of them would even utter his name, or else be killed instantly in a ruthless manner. When pushed into a corner, Muzan's typically calm, arrogant and superior stance collapses, paving the way for panic and fear to take root as he desperately fights for his life, adopting more drastic measures to protect himself. This obsession with survival could well explain Muzan's brutal homicide of three civilians after his first encounter with Tanjiro. Both times he was reminded of two major events where he nearly lost his life, namely his life coming close to ending before his treatment took effect and when Yoriichi overpowered and nearly killed him.

Muzan conducting an experiment Muzan's interest in chemistry. Regardless of Muzan's personal faults, he has repeatedly shown a very notable fondness for both high fashion and higher learning. Whenever shown outside battle, he comes in the appearance of an extremely well dressed individual. In his Tsukihiko guise he dresses in a fedora and suit. On an interesting note his 'wife' Rei is shown in a cloche hat and elegant dress, hinting that he enjoys himself living in wealth and luxury. Muzan is also well known for selling Gyokko's pots which fetch a high price. In his Toshikuni guise, he wears button up pants and a dress shirt, and is shown doing a great deal of studying. When talking to the Upper Ranks, he was casually mixing various chemicals showing he had an expertise in chemistry, more than likely to create a medicine in order to improve his demonic physiology to conquer the sun and/or not need to consume flesh and blood.

However, as Muzan reflects on his life while dying from sunlight, he came to understand and accept Kagaya Ubuyashiki's words to him on the fact that everything inevitably dies and the only true "immortal" thing in the world are someone's emotions, feelings and memories. This realization brings Muzan to tears and genuinely moves his heart, causing him to ironically adopt Yoriichi and Kagaya's belief and focus on leaving "something" behind in order to truly become "immortal".

Abilities Overall Abilities: As the Demon King, the first and the progenitor of his kind, Muzan is the strongest demon in existence.

Combat Form: When in combat, Muzan can adopt a more monstrous and battle-esque form, with a dark-red scale-like mass covering most of his body (prominently on his limbs, his forehead, and the entirety of his lower body), featuring sharp-toothed wide mouths all over of his body, and longer pale white hair. The sharp toothed jaws located all over his body in this form not only serve as his main form of offense in battle, but also have the purpose of helping him recover faster since he can use the jaws to tear apart his opponents and eat their flesh, simultaneously killing his opponents and regaining his strength at the same time.[38]

Muzan brandishing his arm whips Muzan shaping his arms into elongated bladed flesh whips. Arm, Back, and Thigh Whips: Muzan can 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. Each of these whips range from 90 centimeters (35.4 inches) to 10 meters (32.8 feet) long.

Mouth Suction: 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.

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 the 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.[44][45] 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.[46] The same would also presumably happen to a demon if they couldn't withstand the blood's effects, as implied by Muzan.[45]

Consciousness Implantation: Muzan can implant a part of his consciousness into a demon he creates using his blood, provided that he injected them with gigantic amounts of his blood during their creation. As seen where a sliver of his mind was still present inside Tanjiro's mind despite having already been killed by sunlight, and later attempted to sway, control, and coax Tanjiro into "inheriting" his will and stay as a demon.[53] However, a clear difference between his power to "control" a demon and to "possess" him is the fact that he could no longer forcibly take control of a demon and force them to do as he wills and instead he must convince them to do his bidding, giving his victims the chance to resist him and escape from his grasp. Demon Manipulation: Muzan can control demons to a certain extent.

Kibutsuji's Curse: Muzan places a curse on all demons that have assimilated his blood. If any demon divulges his last name "Kibutsuji" out loud, the curse activates, which causes their bodies to stop regenerating and allowing Muzan's cells inside the demon to take over and kill them, regardless of their original intent. This was seen with Susamaru, who had accidentally said his name despite having no malice or ill intent towards him and was still destroyed by the curse, implying that the curse is automatic.[54] However the curse can also be intentionally triggered by Muzan. This was seen when he killed Nakime, who was manipulated by Yushiro.[20] Because of this, many demons regard Muzan with great fear and respect, simply referring to him as "that Man" or "Him" in order to not trigger the curse, while demons within the Twelve Kizuki refer to him as "Lord" or "Master".

Demon Memory Access: Muzan can "see" the memories of demons he absorbed, as seen when he was able to "ask" Tamayo's cells that he had obtained upon absorbing her for information on what kind of drug she had injected into him.[55] Upon being denied and insulted by Tamayo's surviving consciousness, he also showcased the ability to forcibly reveal the desired information by "watching" her memories, as seen when he was able to see her memories of her developing the drug together with Shinobu Kocho and Yushiro.[56] Demon Power Nullification: As explained by Tamayo, as the creator and progenitor of the demon race, Muzan is the only known demon capable of inflicting life threatening wounds capable of completely destroying the cells of other demons without the need of Nichirin Swords or sunlight.[57] This was shown when he punished Akaza by causing his cells to decay all throughout his body without the Upper Rank being able to regenerate from it like he would with any other injury.[58] Telepathy: Muzan has the ability to read the thoughts of those that he has shared his blood with by looking at them.[59] Later, it was shown that he could also send telepathic messages and have full conversations with other demons as well. Muzan has also stated he can sense the location of all demons. However, the further away they are from him, the harder it will be for him to interact and track them.[59] Muzan is also able to see through the senses of other demons.[62] However this ability is limited strictly to what is in their perception, so if a demon's senses are fooled, Muzan is unable to discern the difference as well. Muzan sensing the presence of the Hashira approaching him Muzan discerning the presences of the Hashira spread across a mountain. Extrasensory Perception: Muzan possesses extremely acute senses that even allow him to perceive things outside the normal range of perception, which he displayed by easily discerning the presence of humans instantly even when they were scattered all around a mountain[63] and detecting the wounded Demon Slayers regaining consciousness despite being far away from them.[64]

Genius Intellect: Having lived for over a millennia and gained further experience from the telepathic link with demons he control, 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 also able to evade the Demon Slayer Corps for nearly a thousand years.
