Muzan was easily the strongest antagonist in the Demon Slayer universe, with him being the first and the world’s most powerful demon, capable of creating more demons with a mere snap of his fingers. His paranoia kept him at bay, keeping him hidden from the eyes of the watchful Hashira.

However, if Muzan were to be taken out of his universe and placed in universes with demons who were closer in strength or even more powerful than him, there is a good chance he would not survive. Anime is full of powerful demons that that could give even Muzan a run for his money.

Updated on May 22nd, 2022 by George Voutiritsas: Muzan Kibutsuji has created hundreds of demons either directly or indirectly, and he can control almost every single one of them. He is a terrifying demon and the main foe of the Demon Slayer Corps, capable of fighting multiple Hashira at once as if they were ordinary Demon Slayers. Considering his overwhelming strength, many consider Muzan to be the strongest demon in anime history. He is definitely one of them, but there are a number of demons who are just as strong or stronger. This list has identified several demons who are strong enough to actually beat Muzan, but the anime world is vast, and there are other demons who are capable of defeating the great Demon King as well.

15 The Demon King's Main Ability Makes Him Virtually Immune To Damage (Seven Deadly Sins)

The Demon King raises his sword Against Meliodas In Seven Deadly Sins

The Demon King from Seven Deadly Sins was created by Chaos, and he uses his god-like power to rule over the Demon Clan and the entire Demon Realm. He is a colossal being of immense physical strength and durability, and he is a master swordsman who can manipulate the elements.

His main ability is called The Ruler, and it allows him to invert all attacks directed at him. If Muzan attacks him, he will end up healing him instead, and the effects of his Blood Demon Art will be reversed as well. Unless Muzan wishes to heal him instead, the Demon King will not take any damage.

14 Sesshōmaru's Bakusaiga Can Do Serious Damage To Muzan's Body (Inuyasha)

Sesshomaru and Jaken travel in Inuyasha.

Like his younger brother, Sesshōmaru is the son of the Great Dog Demon. But unlike Inuyasha, he is a full demon, as evidenced by the special markings on his face. Sesshōmaru possesses superhuman physical abilities, as well as flight. He can transform into a massive dog-like demon, and he can produce deadly poison with his claws.

When Sesshōmaru surpassed his father, he summoned his own sword. This demon blade, called Bakusaiga, could cause immense damage to Muzan's body. Bakusaiga's energy triggers an extremely corrosive effect on organic material, which could derail Muzan's regeneration. A single blast from this weapon can kill thousands of demons at once.

13 Femto's Ability To Manipulate Gravity And Space Would Be Troublesome (Berserk)

Griffith Is Reborn As Femto

Berserk is a very dark and violent anime, but some Demon Slayer fans will probably enjoy it. Griffith was regarded as a great leader, but that all changed when he became Femto, a demonic version of himself who has no humanity left.

Femto no longer abides by the constraints of the physical world, and as a result, no man can challenge him. Muzan is not an ordinary man, but even he cannot deal with Femto's spatial manipulation. Femto can use repulsive forces to repel Muzan's physical attacks, and he can trap Muzan in a gravity well that can crush him.

12 Beelzebub III's Power Is Capable Of Causing Calamities (Beelzebub)

Beelzebub III Giving A Happy Greeting

Beelzebub III, otherwise known as the Great Demon Lord, rules over the entire Demon World, and he wishes to destroy the human world because he compares humans to roaches. He is a forgetful and foolish demon, but he is actually a warmonger who can easily defeat other members of the Seven Deadly Sins.

Thanks his electrokinesis ability, he can create and manipulate powerful electricity, and he can create artificial demons to serve specific roles. Muzan's power may be immense, but even his power cannot cause literal calamities.

11 Anos Voldigoad Can Destroy Muzan With His Eyes (The Misfit Of Demon King Academy)

Anos Wielding His Sword Of Ultimate Destriction

In the Mythical Age of The Misfit of Demon King Academy's history, Anos Voldigoad was known as the Demon King of Tyranny. He possesses a multitude of powers, including some that transcend both space and time. Anos' Source specializes in destruction, and his Magic Eyes of Chaotic Destruction allow him to destroy anything in his sight.

These eyes can even destroy the indestructible, which means even Muzan's body would not be able to withstand Anos' gaze. Anos also wields a special demon sword called Venuzdonoa, which is capable of destroying everything in creation.

10 Inuyasha’s Powers Far Outweigh All Of Muzan’s Powers Combined (Inuyasha)

Inuyasha smiles

The title character of Inuyasha can wield the Tessaiga's Kaze no Kizu, and he mastered the Meido Zangetsuha (which could turn into a complete circle) and Bakuryuha techniques. In fact, over the course of the series, Inuyasha was able to defeat his father’s foe, Ryukotsusei, as well as the Panther King.

Unlike Muzan, Inuyasha kept growing stronger and stronger as time passed, giving him the opportunity to perfect his abilities, including being able to wield the mighty Tessaiga for a few seconds.

9 In His Full Form, Sukuna Could Easily Beat Muzan To The Ground (Jujutsu Kaisen)

Sukuna smiling in the rain Jujutsu Kaisen

Sukuna’s powers aren’t at full strength because he does not have control over all of his fingers. Despite that, he’s Jujutsu Kaisen’s strongest antagonist with a surprisingly high amount of cursed energy levels that can only be paralleled by Satoru’s energy levels.

In his weakened state, Sukuna can still regenerate instantly and bring a dead human back to life. This means that in a battle with Muzan, Muzan may or may not die, but Sukuna definitely won’t.

8 Amira's Half Angel Blood Is What Will Help Her Win Against Muzan (Shingeki No Bahamut)

amira glowing demon powers Shingeki No Bahamut

This angel-demon hybrid from Shingeki No Bahamut possesses powers of both sides and none of their weaknesses. In fact, Amira's strength and resistance to attacks were revealed when she literally fell from the heavens to earth and did not get even a single scratch on herself.

Unlike Muzan, she can cover great distances within a matter of seconds, regenerates rapidly, and is almost impossible to catch. Muzan would have a tough time landing even a single punch on her.

7 Sebastian's Body Is Composed Of Otherworldly Material That Muzan Can’t Kill (Black Butler)

Not much is revealed about the demon butler Sebastian in both the Black Butler anime and manga except for two things. The first is that his body is made of materials that do not exist on this earth, meaning no earthly weapon can defeat him. Muzan can use his Blood Demon Art to create flesh swords, but these blades are by no means otherworldly.

Second, unless Muzan possesses a shinigami’s death scythe (the only thing that can hurt or kill Sebastian), he will do nothing but annoy the suave demon because all of his attacks will be completely ineffective.

6 The Demon Muzan Is No Match For Satan’s Blue Flames (Blue Exorcist)

While the Blue Exorcist anime does not reveal many of Satan’s powers, it does showcase how targets of his blue flames burn to death. Additionally, if Satan took over someone's body, they would die within seconds as they would be unable to contain his demonic form.

If Satan decided to use one of these techniques on Muzan, he would be done for because despite all his powers he has no knowledge on how to stop Satan or his powers.

5 Akira's Devilman Form Turned Him Into An Unbeatable Beast (Devilman Crybaby)

Akira transforms into a demon in Devilman Crybaby.

The demon that possessed Akira in Devilman Crybaby, Amon, was such a fearsome creature that he’d earned himself the nickname of the God of War in Hell. As powerful as Muzan is, he would be unable to match Amon’s centuries worth of knowledge and battle experience, seeing how Muzan was always a lone wolf who rarely fought with anybody.

Amon can breathe fire and blast off heat laser beams from his hands, as well as teleport to other places in an instant if things got rough, all of which Muzan would be powerless against.

4 Together With The God Key, Belzebuth Was Pretty Much Invincible (Shingeki No Bahamut)

Belzebuth blue streaks over eyes (Shingeki No Bahamut)

Even if Belzebuth did not have any special powers, he could easily encase Muzan in his glass prison for eternity, seeing how only he himself has the power to break through the prison’s walls.

However, with the dragon Bahamut’s powers by his side thanks to the God Key, Belzebuth would be invincible. This is shown in Shingeki No Bahamut when took the combined strength of humans, angels, and demons to lock away this dragon for good.

3 Cheng Hua, The Disaster Class Demon, Made Even The Heavenly Officials Tremble In Their Boots (Heaven’s Official Blessings)

Being one of the Four Great Calamities, Cheng Hua’s powers were such that he challenged (and defeated) 33 Heavenly Officials in duels. Muzan may be strong, but he would be no match for a powerhouse like Cheng Hua, who earned the reputation of being the deadliest of the Devastation class demons in Heaven's Official Blessings.

In fact, he was so terrifying that he was given the moniker Crimson Rain Sought Flower after he obliterated a Warth level ghost, resulting in a rain of blood that lasted for several hours.

2 Muzan Wouldn’t Stand For 5 Seconds On Satan’s Own Fighting Ground (The Devil Is A Part-Timer)

satan powers (The Devil Is A Part-Timer)

Even though Satan’s powers in The Devil Is A Part-Timer only grew with negative human emotions on Earth, he was still a force to be reckoned with on Ente Isla. The only person who was strong enough to stand up against him was neither a human nor a demon, but a half-angel heroine named Emilia.

Muzan may be the strongest demon in his world, but he’s still a demon and proper hierarchy dictates that Satan, being the strongest demon of all, would obliterate him within seconds.

1 Kurama Is The Most Powerful Nine-Tailed Beast To Ever Exist (Naruto)

Naruto and Kurma Mindspace

Naruto's Kurama possessed unparalleled amounts of chakra that enabled him to cause mass destruction via his energy spheres within mere seconds. He could breathe fire and create tornadoes, both of which Muzan would be unable to defend himself against because he's not an immortal - he can take damage.

With one swipe Kurama could also flatten mountains or create tsunamis and, despite how strong Muzan is, even he would be unable to stand his ground for more than a few minutes against this formidable foe.
