Without Muzan Kibutsuji, the Demon Slayer the world would be free of flesh-eating demons that can regenerate faster than an instant. He stands as the major roadblock in Tanjiro Kamado's ambitious goals, ruling as the demon king whose only weakness is the sun itself.
In his relentless pursuit of true immortality, Muzan Kibutsuji takes on several powerful forms throughout Demon Slayer which brings him closer to his goal. Before Muzan could become a truly immortal being, these powerful forms embodied the terrifying potential of his demonic biokinesis.

Muzan's Cocoon Form tried to reverse Tamayo's drugs
Muzan's Cocoon Form is one of the most disturbing sights in the Demon Slayer. With only his head exposed while the rest of his body remained encased in a thick cocoon of flesh, he isolated himself and purged Lady Tamayo's deadly drugs before they could further destroy his demonic physiology.
Meanwhile, Muzan continues to absorb Tamayo in this unsettling form, mocking her last act of defiance, unaware that four different types of drugs have already sealed his fall later in the series. However, despite this non-combat form, Muzan remained a brutal enemy with a strong determination to kill every demon slayer in the world.

Muzan's Tsukihiko form walked freely among humans and demon slayers
For years, Muzan roamed the streets of Japan undetected by the Demon Slayer Corps, constantly changing his appearance using his god-level biokinetic ability. However, Tanjiro immediately recognized Muzan in Asakusa, even though the villain had assumed the role of Tsukihiko, a loving father and devoted husband.
As soon as Muzan saw Tanjiro's hanafuda earrings, he knew he was a demon slayer. To avoid drawing unnecessary attention to himself, Muzan instantly transformed a passerby into a demon with nothing more than a single scratch. At this point, if Tanjiro pursued Muzan, the latter could have easily killed him.

Muzan's female form killed the Lower Moon Demons
Before the Mugen Train Arc, Muzan surprised everyone Demon Slayer fan with her elegant, geisha-like female form. He looked absolutely gorgeous yet dangerous in this guise, with striking eyes that would make anyone want to avoid his piercing gaze.
Despite this elegant female form, Muzan could easily switch from gentle to brutal, as shown when he killed the remaining lower moons in a flash, except for Enmu. This brutal act was a stark reminder that no demon could defy Muzan, and it is only fitting for the weak to serve the strong until they die.

Muzan's Toshikuni Form Berated Akaza mercilessly
Muzan once assumed the identity of a polite and earnest young boy cherished by his rich parents. He could be seen hanging out in the library reading books while his parents admired him from a distance. Muzan's disguise came with a skin condition that prevented him from going out into the sun.
But despite his vulnerable appearance, Muzan as the young Toshikuni was still the most brutal demon in the series. Not only did Muzan repeatedly slander Akaza in this form, but he also vented his rage at losing one Upper Rank Demon after another to the Demon Slayers. He may have looked calm and collected on the surface, but underneath was a demon king with a short temper and a thirst for demon slayer blood.

Muzan's Heian Era Form feared only one man
Before meeting Tanjiro in Asakusa, Muzan wreaked havoc throughout the Heian era after becoming a demon. He devoured countless people, slaughtered entire armies, and wiped out villages in his relentless pursuit of the blue spider lily. It goes without saying that Muzan during this period was a merciless predator.
However, during this era, even the power-hungry Muzan was humbled by Yoriichi Tsugikuni, who nearly killed him. As a result, Muzan shielded himself to recover, leaving his demon offspring to continue the search on his behalf. After he recovered, Muzan continued his quest while creating an army of demons of higher and lower ranks.

Muzan's demonic infant form was his last defense against the sun
More than anything, Muzan's worst nightmare was not the demon slayers, but the sun itself. After all, the sun could burn his flesh, prevent his regeneration, and, at worst, disintegrate him to death. This unfortunately happened in the final moments of the war between Muzan and the surviving demon slayers in Infinity Castle.
To protect himself from the sun, Muzan used his Biokinesis Blood Demon Art to wrap himself in an armor of flesh and transform into a giant demonic infant. Although this form is one of the most disturbing in Demon Slayerit also represents Muzan's greatest defensive alignment.

Muzan's true demon form turned him into a great calamity
Muzan's True Demon Form is far superior to his previous forms when it comes to destructive power and overall combat ability. Emerging from a cocoon made of flesh, Muzan finally looks like a nightmare incarnate, with extended arms that look like long-bladed whips. With their exceptional range, these deadly whips can easily slaughter anyone who comes into their range.
Furthermore, in this form, Muzan confidently assumed that his power was more or less equivalent to a great calamity that people like Tanjiro would not be able to defeat, no matter how long they fought. Meanwhile, this is Muzan's final form in Infinity Castle, where he meets Tanjiro, Giyu, Yushiro, Mitsuri, and Obanai.

Muzan's final battle form nearly finished off the Demon Slayer Corps
Muzan's blood demon art was finally put to the test in its final battle form. With spines, tentacles, and whip-like arms erupting from his body, Muzan transformed into a killing machine capable of attacking in all directions simultaneously. In this grotesque form, he maimed several demon slayers, dismembered the surviving Hashira, and forced Tanjiro, Inosuke, Zenitsu, and Kanao into a desperate battle of attrition.
Despite being aged by 9,000 years through Tamayo's aging drug, Muzan's Final Battle Form remained powerful enough to push his enemies to their absolute limits. For example, the gaping mouth in Muzan's chest expelled a poisonous fluid that paralyzed Tanjiro and Obanai, while a second beastly mouth viciously attacked Sanemi.

Muzan almost won by sending his blood and memories into Tanjiro's Demon King Form
Getting rid of Muzan Kibutsuji for good was not an easy undertaking. Even as he took his last breath, Muzan desperately held on to power by transferring his blood, as well as his memories, to Tanjiro, reviving Sun Breather as the new Demon King of the Taisho Era. In the process, Tanjiro regained his left arm and even had his poisoned eye cured.
Under Muzan's influence, Tanjiro, in his wild Demon King form, posed an incredibly dangerous threat to all the surviving members of the Demon Slayer Corps. Not only did Tanjiro conquer the sun, but he was also motivated by Muzan's relentless desire to end the Demon Slayer Corps once and for all.
