Yoriichi's appearance

Physically he is similar to his brother in his human form, except for slight differences such as the fact that he has possessed his Demon Slayer Mark since birth, which is located exactly in the same position as Kokushibo's.

He was also extremely humble, seeing himself as just another man and no one special despite his godly attributes; one example being the time he performed the Sun Breathing postures for Suyako at her request and almost seemed embarrassed afterward. Despite being mostly indifferent, he experiences strong emotions; he mourned the loss of Uta and his unborn child for ten days straight and was brought to tears upon seeing the joy Sumire showed at simply being lifted up.

Muzan's appearance

In terms of physical appearance, Muzan appears to be a young man in his early 20s; he has short hair styled in curls with some strands hanging over his forehead. Like all Demons, Muzan has feline-like eyes, plum-red in color, and pointed blue fingernails. As a human, Muzan dressed in the Heian Era style wearing a traditional hitatare, had longer hair reaching down to his lower back, and his eyes were completely dull. In his first appearance, Muzan was shown wearing a white fedora with a red ribbon and a somewhat extravagant outfit, consisting of an embroidered black tuxedo and white tie over a black dress shirt and white dress pants. He also wore black loafers. As seen in Rui's memories of meeting Muzan, the Demon King once sported a slightly different hairstyle and outfit in the past. When he first met Rui, Muzan's hair was straighter and parted down the middle. He also wore a loose-fitting tuxedo and a white half-cape over it. Muzan has the ability to change his physical appearance to disguise himself, appearing either as a black-haired woman in a kimono or as a young child. His ability to disguise himself was so perfect that he could even change his appearance and confuse his own subordinates.

Muzan's Appearance (2)

During the meeting with the Lower Moons, Muzan takes the form of a woman with a bun hairstyle while wearing a long black yukata, causing the rest of the Lower Moons to initially fail to recognize him. [11] Later, he transforms into his final cover identity: the sickly adopted son of an elderly couple, taking the form of a young boy with pale white skin and silky-smooth, carefully combed black hair. His primary attire with this disguise is a white button-down shirt and black shorts with long socks and loafers. Following Tamayo's failed attempt to eliminate him after leaving his flesh cocoon, Muzan adopts a new physical appearance consisting of his skin becoming paler, his hair becoming longer, and taking on a graying white hue due to the effect of the drug created by Shinobu to force his body to age; on its limbs is completely covered in thick jaws with large, sharp teeth and a strange, dark red mass completely covers its skin. It is later revealed that Muzan has a series of scars all over his body due to the injuries inflicted during his first battle against Yoriichi, which were burns caused at a cellular level which never fully healed despite the hundreds of years that passed since their confrontation. These wounds are not visible to the naked eye and come to light as they weaken.

Muzan's Personality

Muzan is callous, ruthless, and exceptionally intelligent. He sees no value in any human he has encountered and shows little value in his own subordinates. Rarely visually annoyed or happy, he appears completely flat and aloof on most occasions, even when cruelly murdering his own subordinates. The only times he shows emotion is when his vision of perfection is advanced or when his 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 this (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 almost all times, accentuating his detached behavior. The most prominent trait that Muzan possesses is extreme narcissism, megalomania and an obsession with becoming the perfect being possessing immortality. This last behavior is derived from his own Thanatophobia by having experienced closeness to death literally since his own birth, both in his days as a human and in his subsequent encounter and confrontation with Yorīchi Tsugikuni, the first Demon Slayer to use the Sun Breathing; an encounter which almost ended his life and ended up leaving Muzan with a strong post-traumatic stress disorder causing a violent reaction when he remembers his own near-death experiences, being able to overcome this trauma once he understands, already in his last moments the words of Kagaya Ubuyashiki where he understood that although living beings, especially humans, are destined to die, their thoughts remain in eternity which leads him to transfer his cells into Tanjiro to turn him into a Demon who can do what he could not: overcome his weakness to sunlight.

Muzan's Personality(2)

Having had nearly 1,000 years to live and observe, along with almost no real challenges, his extreme self-centeredness is almost expected. Consider that almost nothing is his concern except overcoming his inability to walk in the sun, which is his main drive. His long life and primary obsession with achieving immortality have led him to want every plan he concocts to be absolutely perfect, and his megalomaniacal behavior blinds him to 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 deems weak, even if the failures are minor. His self-centeredness and delusional sense of self-worth are so great that he cannot bear to be mocked or corrected in any way, believing that others exist only to serve him. It also means that he rarely takes any opponent or threat seriously. He brutally killed a pair of drunken men simply for being rude to him, and killed the woman who was with them when she had done nothing, all the while proclaiming his own perfection and superiority over them. This event hints that Muzan has unpleasant memories of his weaker, human past, and is well aware of his unnaturally sickly appearance, coming on the heels of a long-standing denial that he is not healthy, ill, let alone on the verge of death. In all likelihood, a bitter reminder that he is still imperfect. When he finally managed to confront Kagaya Ubuyashiki, the man responded to Muzan in a tone of pity and sadness for the life he had led. In Muzan's mind, these only registered as insults and threats, which he used to justify his hatred towards humanity and Demon Slayers. Being someone so obsessed with the idea of ​​perfection, Muzan despises the very concept of change; be it change of circumstances, physical, emotional, or change of any kind.

Muzan's Personality(3)

He equates change with decay, and thus evidence of imperfection. In his own words, he loves things that remain unchanged, constant, and in a state of permanence. At the same time, he views one's humanity as a sign of weakness, believing Gyutaro to have lost because he was still attached to his sister Daki, even mocking the Upper Moons, stating that they were now ranked in order of how much humanity they had left. Gyutaro's defeat at the hands of the Demon Slayers notably enraged Muzan as he saw how the status of the Upper Moons was altered after 113 years, causing him to lash out and demand further self-sacrifice from the remaining Upper Moons. This might also help to explain his brutal execution of the Lower Moons, as their membership was in a constant state of flux and he grew tired of managing them. On the contrary, he is pleased whenever he sees progress, and is overjoyed by Nakime's growth after becoming the Upper Fourth Moon. In addition to all of the above, his megalomania and sense of considering himself an indestructible omnipotence is such that he compares himself to natural disasters, i.e., something far beyond what humans can compare to and combat. As a result of this, he believes that Demon Slayers are a group of deviants who are unable to accept the natural order of things and resume their lives as normal when other people simply move on after a tragedy. His analogy is evidence of his complete inability to feel sympathy or remorse for his actions, given that none of the murders he committed (directly or indirectly) were the result of an accident, but rather carefully orchestrated acts of pure evil.

Muzan's Personality(4)

His airs of superiority are not only evident in his behavior but also in his way of dressing, choosing to wear quite formal Western clothing and expensive kimonos based on the appearances he has been seen adopting throughout the series, so we can deduce that Muzan loves to live an opulent lifestyle, which combined with his terrifying presence make him quite a well-rounded character. Muzan has proven to be quite manipulative and cunning, being able to blend into human society normally, even having a family of his own to add. A long life and continuous practice have allowed him to take on many roles in society and perform them capably, including children and women if he so chooses. This life has also given him great intelligence and the ability to think tactically. Muzan is a quick thinker and strategist who is able to deal with unfavorable situations quickly and quite well, though this may also be due to the loss of his subordinates meaning nothing to him in the long run. Due to his perceived superiority and two-faced nature, he feels little attachment to his minions, using and discarding them like disposable pawns at will. He does not allow his subordinates to question his will, regularly enacting brutal retaliation if they do. Many of his subordinates, in turn, are greatly afraid of him and carefully measure their words and thoughts for fear of saying or thinking anything to displease him. He is able to sway many Demons to his side with promises of power, vengeance, and greatness, as long as they serve him. His intelligence and manipulation shine through here, as many find the promises quite alluring, as he encounters many of his subordinates at their lowest, when their emotions are easy fodder for him.

Muzan's Personality(5)

Unfortunately, all these promises are ultimately false, as Kibutsuji only cares about himself and has no qualms about killing his own men to protect his own safety. When not hiding behind a facade, his malice and overflowing violent intent are so great that others can perceive them. In particular, Yorīchi Tsugikuni described him as resembling a boiling magma spewing out of an erupting volcano ready to consume everything. As proof of his high level of cruelty, he curses his subordinates in a terrifying manner so that none of them can utter his name, or else they will be killed instantly in a rather ruthless manner. Thus, the Demons he creates, even those who become his subordinates, including the Upper Moons refer to him as that man, carefully measuring their words to refer to the progenitor Demon for fear of being cruelly killed. Interestingly, this almost paranoid sense of self-preservation stands in stark contrast to his megalomania. When cornered, the collapse of Muzan's substantially calm, arrogant, and superior stance paves the way for panic and fear to take root as he desperately fights for his life, adopting more drastic measures to protect himself. Obanai Iguro described him as someone who possesses no sense of self-preservation. honor similar to that of the samurai, but as a despicable being capable of doing anything to stay alive during their final confrontation. This obsession with survival could well explain the brutal murder of three civilians after meeting Tanjiro the first time, as he was made to remember his sick past with the former, and his encounter with Yoriichi with the latter, due to her hanafuda earrings. the two important events where he almost lost his life.

Muzan's Personality(6)

Despite the many facets of his personality that he displays throughout the work, fully compensating for his insatiable ego and desire for perfection, Muzan is incredibly cowardly. He always avoids conflict whenever possible, as evident in his encounter with Giyu Tomioka and Tanjiro Kamado. He states that the duo who managed to survive should already be enough and that they should just live in order to earn their wages and stop the cycle of revenge. This trait also complements his manipulative nature, bending many Demons to his will to do his bidding as long as he does not get his hands dirty. In the final confrontation between him and the Demon Slayers, Muzan attempted to escape on numerous occasions, either by splitting up or simply running away, even demanding several times that the remaining Slayers simply die and stop fighting, once again cementing his cowardly nature. However, when completely defeated, in his last moments of life while being consumed by the sun's rays, Muzan showed a more vulnerable side to his personality. It is revealed that Muzan's true fear of dying and immense desire to live and survive was due to him being born "stillborn", where his heart constantly stopped in his mother's womb and he was thought to be stillborn until he struggled to breathe before his cremation. Muzan's desire for "life" and his near-constant struggles while human built his obsessive ambition to survive, and he truly felt vulnerable whenever he was reminded of his human frailty. However, even when on the brink of death, he still does not regret murdering and devouring humans for a thousand years, stating that he could not remember a single person he has killed.

Muzan's Powers and Abilities

As the Demon King, Muzan's powers surpass anything seen before. Muzan is so strong that he was able to withstand a confrontation with five Pillars and Tanjiro at the same time. So strong is he, that he was able to leave Tanjiro on the verge of death, as well as several Pillars, if not for the timely intervention of Chachamaru and the antidotes he supplied to the Pillars and Tanjiro so they could survive the effects of the poison present in his blood. After 30 minutes of combat, Muzan manifested whips from his legs, which increased his attack speed exponentially, to a point where he instantly defeated five exhausted Pillars: Gyomei, Giyu, Sanemi and Obanai, as well as Zenitsu and Inosuke at the same time, while leaving Kanao paralyzed with fear and with her sword broken. It is later revealed that Muzan was becoming increasingly slower due to the effects of the aging medicine provided by Tamayo, which accelerated his age massively. Despite everything, he was able to subdue the pillars that faced him, as well as Tanjiro who was just learning to use the Sun Breathing. His strength, speed, stamina and regeneration capabilities are superior to any conventional demon and are even considerably superior to those of the Twelve Demon Moons, adding also his unique amount of abilities that he has; below is a list of his powers.

Muzan's physical abilities

Unique Body Constitution: Unlike other demons, Muzan possesses a unique body with which he can make use of his complex abilities. Inside, he possesses five brains and seven hearts. If a simultaneous attack affects these vital organs, he will be considerably weakened. In addition, Muzan can move his vital organs within his body in order to avoid a fatal blow. Body Manipulation: Muzan can explode himself at any time when his life is in danger, splitting his body into several fragments of flesh, which then regroup to escape from his enemies. He was able to split himself into 1,800 pieces of flesh, a good portion of which were destroyed. He used this ability to escape from Yoriichi during their confrontation. Superhuman Strength: Muzan is extremely strong despite his frail appearance. He can deliver powerful blows capable of sending a human flying with a single kick or smashing their head against a solid wall without the slightest effort. Speed: Muzan is also extremely fast, being able to attack an ordinary human with his claws and infect them with his blood fast enough for no one to notice. Even when one of his Lower Moons tried to escape from him, being able to get away a considerable distance, without help from Nakime, in the blink of an eye he had already decapitated it.

Muzan's Physical Abilities(2)

Regeneration: Like all the Demons he creates, Muzan can regenerate from any kind of wound, even recovering his limbs when they are severed; He is also capable of withstanding a gigantic short-range explosion, being able to rebuild his body as quickly as it is destroyed, but the highest point of his regeneration is that he can even regenerate his own head when it is cut off with a Nichirin weapon, unlike the Demons he creates, which die when decapitated, with direct exposure to sunlight being the only way to kill Muzan. Cellular Consciousness Transfer: If Muzan is on the verge of death, he can transfer his consciousness through his cells to the nearest human he can find. He tried this without much success with Tanjiro, whom he tried to possess.

Muzan's unique abilities

Demon Blood: It is one of his main abilities; with his blood, Muzan can turn an ordinary human into a Demon who will be under his control thanks to a component present in his blood which when entering the bloodstream of a human, causes their cells to begin to transform, thus turning a human into a Demon. The physical changes and powers that the newly created Demon acquires vary depending on the number of people he eats, and can even use a supernatural ability called Demon Blood Techniques by manipulating his blood for various offensive or defensive purposes. However, if a human receives Muzan's blood in large quantities, their cells will not withstand the physical changes and will self-destruct, causing a horrific death by causing the person to literally dissolve into their own flesh. Nullification of another Demon's regenerative qualities: As Tamayo explains, Muzan, being the one who gave rise to all Demons, is the only one capable of killing others of his kind by nullifying the regenerative qualities of their blood and cells, being able to inflict mortal wounds on any Demon who dares to oppose him, destroying their body completely without the need to expose it to sunlight or through the use of Nichirin Weapons. Curse: When Muzan turns a human into a Demon by injecting their blood, he transmits his cells through their bloodstream, ensuring that he shares a bond with the Demon; this allows him to know their location, read their minds, sense their presence, and, if he wishes, destroy their cells. Muzan uses this last option to destroy the Demon if they dare to reveal their identity or attempt to betray him. However, if a Demon has enough willpower to resist Muzan's control by refusing to eat human flesh or drink human blood, they can escape the curse.

Muzan's Exclusive Abilities(2)

Omnipresence: Muzan can see through his eyes what the demons he created see, thus ensuring that he is not betrayed by his creation. Shared telepathy with his creations: Muzan has telepathic powers to hear thoughts, this way he can know what the Demons he has created are thinking. Extrasensory Perception: Muzan can sense the presence of humans and demons alike, and can also sense the bloodthirst of a being and thus know its intentions. Absorption: Muzan possesses the ability to assimilate and absorb any individual who comes into contact with his body, also gaining their qualities and powers if he absorbs a Demon. Due to this ability, he has focused his goal on absorbing Nezuko, due to her ability to resist sunlight. Shapeshifting: Muzan can change his physical appearance to disguise himself, appearing with a different aura and presence to confuse his enemies and allies alike. Muzan has been shown to take many forms, from a woman to a child, and even turning into a fang-wielding mass of flesh, which he uses to tear apart his opponents.

Muzan's Combat Form

Combat Form: Once Muzan leaves the flesh cocoon where he was imprisoned along with Tamayo, he adopts this new form in which his speed and strength are severely increased despite the weakened state in which he was left due to the drug that Tamayo tried to introduce into his body, he was able to easily eliminate an entire squad of Demon Hunters and devour their bodies as soon as he left the flesh cocoon where he was. The mouths with sharp teeth located all over his body once he adapts 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 his opponents apart and eat their flesh, simultaneously killing his opponents and regaining his strength at the same time.

Muzan's Demonic Blood Technique

Demonic Blood Technique: Dark Blood: Thorny Roots: With this blood technique, Muzan manipulates his flesh and blood to create a barbed wire which he uses to trap his enemies.
