What Is Muzan’s Final Form & How Strong Is It?

Muzan Kibutsuji is the main antagonist of Demon Slayer. He is a Demon, being the first of his kind, who has lived for more than a thousand years, being as such, the one responsible for the origin of the other demons, responsible for having corrupted Michikatsu Tsukiguni and being the one who murdered Tanjirō’s family and Nezuko, turning the latter into a Demon, being the trigger for Tanjirō’s desire for revenge towards him. Building on that fact, we have decided, in this article, to tell you a bit about his powers and abilities and how he would fare against numerous other characters from the Demon Slayer series, but with a twist – namely, we are going to focus on Muzan’s final infant form, seen during the final battle in the series.

The article is going to be divided into two major parts. The first one will present Muzan’s final form and its powers and abilities, while the other one will be a short comparison of this form’s powers and abilities to the powers and abilities of other characters, divided into several subsections. These will not be detailed analyses, just brief comments so you can understand how powerful Muzan’s final form was in the Demon Slayer lore.

Muzan’s final form and its powers

When engaged in combat, Muzan can appear more monstrous, leaving his chest exposed and his limbs covered with a dark red mace with big, pointed teeth. Although he lost a lot of energy fighting Tamayo’s human-transforming medicine, he was nevertheless completely capable of outwitting a number of low-ranking Demon Slayers and devouring dozens of them within minutes.

This form greatly enhances his strength, speed, reflexes, and power. While in this mode, he has sharp-toothed jaws/mouths that are scattered throughout his. These jaws/mouths are not only his main point of attack in combat but also help him heal more quickly by allowing him to tear through his foes and consume their flesh.

Muzan may strike a common person with his claws and infect them with his blood quickly enough for no one to notice because of his speed. Even when one of his Lower Moons attempted to flee from him and managed to go a fair distance without Nakime’s assistance, he quickly beheaded him.

The highlight of Muzan’s regeneration is that he can even regenerate his own head when it is severed, unlike the demons he creates who die by having their heads severed, with the Sun Breathing Style being the only thing that can kill them. Muzan can regenerate from any kind of injury, even recovering his limbs when severed; he can also withstand an explosion at close range, rebuilding his body as fast as it is destroyed.

Muzan’s Blood Demon Art is Biokinesis. It might seem like a relatively weak power, but Biokinesis allows Muzan to use his body amazingly. He has incredible shapeshifting powers, far surpassing similar abilities of other Demons. He also has a total of seven hearts and five brains, a fact that, combined with his Blood Demon Art, makes him almost immortal, as it is exceptionally difficult to kill him (he can, in fact, survive if even a small piece of him is not destroyed). He can create flesh clones of himself and turn others into Demons using his blood.

Now, this was a rough overview of Muzan’s general powers and abilities because it was important for us to provide you with a proper introduction. In that aspect, we have to say that Muzan’s battle form, which we have described above, is not his final form. Namely, near the end of his final battle against the Corps, when he realized that the sun was about to rise, Muzan created a special flesh armor that turned him into a large demonic infant. This demonic infant form is actually Muzan’s final form, and it was in this form that he was ultimately defeated.

Now, we know three things about this form. First of all, it is the ultimate manifestation of Muzan’s Blood Demon Art, as we have described above, and it shows just how powerful it was. Secondly, this final form gives Muzan amazing strength. He becomes incredibly strong, so strong that only Himejima was able to hold him down and prevent his escape, and Himejima is incredibly strong; the other Demon Slayers stand no chance against him.

He was also able to crush cars with ease in this form. Finally, the form is a defensive fortress as well as a power boost, as it makes Muzan incredibly durable; it even allows him to resist the sun longer, although it doesn’t give him complete immunity. It is not known how it influences his speed.

How powerful is Muzan’s final form compared to other Demon Slayer: Kimetsu no Yaiba characters?

This section will compare Muzan’s final form to some other strong Demon Slayer: Kimetsu no Yaiba characters. These will be brief comparisons whose main goal is to give you a general idea of his powers and abilities.

Muzan Kibutsuji vs. Yoriichi Tsugikuni

This is truly an interesting match-up, knowing the history between Muzan and Yoriichi. We know that Muzan is the most powerful of all Demons and the creator of all the Demons that came after him. His weaknesses are the same as those of the other Demons, but his powers and abilities far surpass those of any other known Demon in the series. Using his powers, he has turned numerous people into Demons and has organized the most powerful ones in the Twelve Kizuki. These are all known facts, and despite all of this, Muzan was weaker than Yoriichi. The two of them actually faced each other in a fight centuries ago, as is known.

While Muzan thought that Yoriichi was simply going to be another one of his victims, Yoriichi could surpass him almost effortlessly. He would have succeeded in killing him had he known Muzan’s tricks, which enabled the Demon King to survive. But, from that moment on, Muzan Kibutsuji was in mortal fear of facing Yoriichi again, which is why he mercilessly hunted all those who knew the Sun Breathing Style; he was, of course, not successful in killing Yoriichi, who was the only character that Muzan feared out of the depths of his soul.

Now, we don’t actually know how Muzan’s final form would do against Yoriichi. However, seeing how Muzan was, notwithstanding the final form, still afraid of Yoriichi, we assume that he would not win even in this form.

Muzan Kibutsuji vs. the Twelve Kizuki

We have already established that Muzan was, even in his base form, more powerful than all of the Demons he had created. Based on that fact, we can easily conclude that in his final form, he would easily defeat all of the Kizuki, even the Upper Ranks (as he would simply trash the Lower Ranks), and even Kokushibō, who was the only Demon Muzan actually respected and was not willing to underestimate.

In his final form, Muzan was so powerful that he could simply destroy Daki and Gyūtarō practically at the same time; Kaigaku wouldn’t really be a challenge at all; Gyokko’s essence would be destroyed easily; Nakime’s powers might pose a challenge for a short time, but Muzan would find her eventually and kill her, as he did; none of Hantengu’s clones would really be a match for him either; as for Akaza and Dōma, they might be powerful, but neither of them could beat Kokushibō, which means that Muzan would beat them as well. Muzan has amazing control over his Demons due to his blood flowing through them, which would eventually be enough for him to defeat them.

Muzan Kibutsuji vs. the Demon Slayer Corps

This is a very versatile category, and while it usually depends on whom the protagonist is fighting, in this case, we can only confirm our firm opinion that Muzan, in his final form, would be able to defeat every single Hashira member, but only individually. None of them, not even Gyōmei and Obanai, have the skill level necessary to defeat Muzan in his final form, and no matter who comes at him, the infant demon will be able to defeat them.

Sure, Gyōmei could hold him off physically using his strength, and Giyū and Tanjirō could injure him, as was Obanai, but these were all individual attacks that did some damage but were not enough to destroy the infant demon. Plus, you have to consider that Muzan was exhausted by then and that the sun was rising, significantly weakening the Demon King, but still not enough to lose.

On the other hand, a combination of Demon Slayers would be able to defeat the Demon King, especially all of them together. Muzan’s infant form is usually a last-ditch resort for the Demon, meaning that he would be exhausted by time. A combination of several powerful Hashira would be enough to defeat him, but only if they would attack together.
