Muzan sent demons after Tanjiroto kill him, and when one of them spoke his name, he was killed by the Demon Curse.
As a result, the secrets of his powers and his whereabouts are always secret, and he cannot be found.
That’s why all the Hashira were surprised when they heard that Tanjiro had met Kibutsuji Muzan during the Hashirameeting arc.
This is the most dangerous ability of Kibutsuji Muzan, and it resulted in the death of most of the Hashira and demon slayers.
This ability allows Muzan to manipulate his cells and create various extensions or change the shape of his body.
During the final battle, Muzan used this ability to procure many whip-like structures with large mouths on them that had sharp teeth to tear off the demon slayers.
The whips land powerful and quick attacks which are hard to dodge.
This long-range offence gives Muzan an edge over the Demon Slayers in battle as they must come close to him to land a strike with their blades.
4] Shockwave scream:
This is another one of Muzan’s dangerous abilities.
It causes internal destruction of the body, paralysis, and tremendous pain.
When the Upper Demon Moon Three Akaza failed to bring the Blue Spider Lily and kill the Flame Hashira, Kyojuro Rengoku, Muzan left him vulnerable by just pointing a single finger at him.
This ability is very dangerous, and even the Upper Demon Moon Three, whom even the Flame Hashira, Kyojuro Rengoku, could not defeat, was vulnerable and on the brink of death.
5] Ability to change form
The Demon King, Kibutsuji Muzan, has the ability to change form.
He can disguise himself as an individual and thus can mix in the crowd like a normal human.
So far, we had seen the Demon King as an Adult Male with a daughter and a wife, a young male child with skin problems with sunlight, and a beautiful adult woman (when he killed all the Lower Demon Moons).
The other two forms of Muzan Kibutsuji are not shown in anime yet, but according to manga, he has his Final Demonic Form where he uses his Biokinesis ability to fight demon slayers at long range and his giant infant Form where he tries to shadow some part of his body by turning into a giant baby when exposed to sunlight in the Final Battle Arc.
Does the strongest demon Kibutsuji Muzan have any weakness?
The strongest demon in Kibutsuji Muzan is also vulnerable to three things.
Those are the only ways to defeat him, but unlike other demons, it takes a lot even for those techniques to affect him because of his superhuman abilities.
The Demon King is vulnerable to Sunlight. Like any other demon (except Nezuko), Muzan Kibutsuji cannot withstand sunlight, and his cells start to burn.
Sunlight is the only way to defeat the strongest demon, as its regenerative abilities can heal any wounds instantly.
Crimson Red Nichirin Blade is another way to fight the strongest demon.
A Nichirin Blade turns crimson red when the Demon Slayer unleashes his Demon Slayer Mark, and the temperature of the blade rises due to the friction created while fighting.
It has the most power of sunlight and can momentarily stop cell regeneration.
Lastly, complex poisons are another way that can weaken the demon king.
But his supernatural abilities can wear off the poison in a short span of time and make him immune to it.
So, if large quantities of complex unknown poison are used, it can weaken even the strongest Demon to ever exist.
So, what do you think about the Demon King Kibutsuji Muzan? Isn’t he the strongest demon to ever exist? And what abilities of Muzan Kibutsuji did you find the most dangerous?
