Demon Slayer: Top 10 Most Powerful Demons Of All Time

10 Kaigaku

Kaigaku was a former demon slayer and the successor of Zenitsu’s master. He eventually becomes a demon and the Upper Moon Six after betraying the Demon Slayer Corps. After becoming a demon, Kaigaku possessed formidable powers. He retained his ability to use Thunder Breathing techniques from his days as a demon slayer. He enhanced them with demonic power, making him much more deadly. 

His lightning-fast attacks became even more unpredictable and devastating, complemented by the typical demon traits of superhuman strength, speed, and regeneration, elevating him to a threat level on par with some of the series’ most dangerous demons. 

Kaigaku’s most notable battle is against his former fellow disciple and current Thunder Breathing user, Zenitsu Agatsuma. This intense and personal fight highlights their clashing combat styles and diverging paths and philosophies.

09 Gyutaro

Gyutaro is a powerful demon, one of the Twelve Kizuki, ranking as a former Upper-Rank Six. He entered the scene as one of the strongest demons in Entertainment District Arc. He made a dramatic entrance after the Sound Hashira, Uzui, cut off the head of Daki, revealing Gyutaro to appear from her skin. 

Contrasting sharply with Daki’s beauty, gyutaro’s repulsive appearance is matched by his unique ability to detach his flesh and blood, which he chillingly shapes into a pair of dual scythes. These monstrous weapons are not merely for show. When combined with his Blood Demon Art, they become even more lethal, as Gyutaro infuses them with a deadly poison, turning every slice and slash into a potential death sentence. 

Together with his sister, Gyutaro presented an overwhelming challenge, nearly overpowering four demon slayers simultaneously, including a Hashira. However, the intervention of Uzui’s ninja wives and their clever use of wisteria-infused daggers ultimately led to the downfall of the demonic siblings.

08 Gyokko

Gyokko marks his entrance in the anime during the Swordsmith Village arc, claiming the notable rank of Upper-Rank Five among the demons. He is characterized by his peculiar nature. He finds delight in the small details and harbours a deep love for the king of demons, Muzan, striving earnestly to gain his approval.

Among the Twelve Kizuki, Gyokko stands out as one of the most unsettling figures, partly attributed to his strange and almost disturbing appearance, similar to an unsystematically assembled collection of doll parts. 

Drawing from his childhood fascination with fishing and water, Gyokko wields powers that are as unique as they are formidable. He can summon massive fish-like entities, teleport, and trap his victims within his mystical pots. These abilities make him a potent force, as seen during his battle with Mist Hashira.

07 Hantengu

Hantengu appears as a central antagonist in the Swordsmith Village arc, occupying the dreadful position of Upper Rank 4. This ranking cements him as one of the most powerful demons in the series. Despite his seemingly scared behaviour, Hantengu’s actual danger lies in his ability to generate four distinct clones through his Blood Demon Art, each embodying a different facet of his emotions.

Underestimating Hantengu based on his cowardly exterior is a grave mistake. The Anger clone wields electricity as its weapon. In contrast, the Joy clone boasts wings, sharp talons, and a devastating supersonic screech. The Sorrow clone engages enemies with an impressively long-reach spear, and the Pleasure clone commands powerful wind gusts with a leaf-shaped fan. 

The Hatred clone can absorb the powers of the other clones and manipulate wood, enhancing its threat level significantly. Finally, the Resentment clone can transform into a colossal form, making Hantengu an opponent of terrifying proportions.

06 Akaza

Akaza, the Upper Rank 3 demon, might be the most despised character in the series, especially after his appearance at the climax of the Mugen Train arc. Akaza appears near the arc’s end, killing the Fire Hashira, Kyojuro Rengoku. His ability to overcome Rengoku and his formidable breathing techniques earn him a spot among the most noteworthy demons. 

He’s an exceptional martial artist who can predict and counterattack with unnatural agility, making him nearly impossible to defeat. His durability is supernatural, allowing him to regenerate from severe wounds instantaneously. 

Moreover, his Blood Demon Art,  known as Destructive Death, is based on the Soryu Style. He unleashes invisible, shape-shifting shockwaves and extrasensory techniques, targeting opponents’ weaknesses with lethal precision. These abilities make Akaza a terror on the battlefield, feared by even the powerful characters.

05 Nezuko

Nezuko Kamado is a central figure in Demon Slayer. She is distinct from demons due to her ability to resist and ultimately conquer the sun, a feat previously deemed impossible for her kind. This remarkable achievement occurred during her intense battle with Upper Moon 4, Hantengu. Theories suggest her resistance is due to her lineage as a Sun Breathing user and her retained humanity, as she never consumed human flesh. 

Her Blood Demon Art, Pyrokinesis, allows her to invoke pink flames that harm only demons, leaving humans unscathed. She exhibits immense power in battle and enters an almost berserk state, her body adorned with vine-like patterns enhancing her ferocity.

In a critical moment during Tanjiro’s confrontation with Daki, Nezuko transformed, gaining a significant increase in size and strength, marked by a pronounced horn on her head. In this formidable state, she fiercely combated Daki, with her limbs regenerating at an astonishing rate, outpacing the Upper Rank 6 demon’s ability to inflict damage. This transformation underscores Nezuko’s unique and powerful presence within the “Demon Slayer” narrative.

04 Doma

Doma holds the Upper Rank 2 position within the Twelve Kizuki. He has successfully eliminated numerous Hashira, garnering a formidable reputation. Doma’s indifference to life is chilling, coupled with his extraordinary tolerance for pain, as evidenced by his ability to inflict harm on himself without a reaction.

His unique talent neutralizes the lethal demon poison derived from wisteria flowers, granting him a substantial edge over other demons.
Armed with an iron fan, Doma excels in Tessenjutsu, a martial art that surpasses even Akaza’s abilities. 

Additionally, he possesses the power to telekinetically control ice, using it to immobilize and absorb his enemies. This lethal combination of skills, indifference, and combat prowess solidifies Doma’s status as a daunting force within the Demon Slayer universe.

03 Kokushibo

As an upper-rank-one Demon, Kokushibo is the most powerful entity within the Twelve Kizuki hierarchy. While most demons begin as ordinary humans, Kokushibo’s lineage is exceptional, tracing back to Yoriichi Tsugikuni, the most legendary Demon Slayer in history. His reputation is built on centuries of conflict with demon slayers, during which he thoroughly studied their techniques and refined his strategies to near perfection.

Not only is Kokushibo a battle-hardened warrior, but he also possesses the rare ability to employ the Hashira’s breathing techniques, setting him apart as a unique and deadly force. This combination of skills places Kokushibo at a distinct advantage, allowing him to surpass even the strongest hashira, Gyomei Himejima. 

Kokushibo’s signature Crescent Moon Blades Blood Demon Art allows him to conjure crescent moon-shaped blades from his flesh katana. These attacks can vary in size and intensity but invariably result in his opponents being devastatingly sliced apart. His techniques and heritage make Kokushibo a uniquely dangerous and influential figure.

02 Tanjiro Demon Form

Tanjiro Kamado’s transformation into a Demon King Tanjiro occurs at a critical juncture in Chapter 201 of the manga, following a fierce battle against Muzan. This change saves Tanjiro from the brink of death. It grants him significant power and the potential for sunlight immunity, much like his sister Nezuko. 

His transformation is marked by physical changes such as slit-pupiled eyes, flame-patterned Demon Slayer marks, claws, and spine-like protrusions on his back. Despite his brief tenure as a demon, his powers were on par with the Upper Moons, if not surpassing Muzan himself. 

Tanjiro’s extraordinary regenerative abilities, newfound resistance to sunlight, and mastery of the Sun Breathing technique skills made him virtually invincible. This massive transformation makes Tanjiro a formidable entity, feared even by his companions.

01 Kibutsuji Muzan

Demon King Muzan is the original creator of all demons. He is esteemed and feared by his followers. Notably, Muzan’s singular vulnerability is his sensitivity to sunlight. Despite this, his remarkable regenerative abilities enable him to recover swiftly, even from decapitation, setting him apart from other demons. 

Muzan has demonstrated his overwhelming strength and agility by single-handedly combating over a hundred demon slayers simultaneously. His prowess is such that even Kokushibo’s abilities lie nowhere in comparison. Facing the collective might of nearly every Hashira, Muzan showcased his indomitable endurance and power.

His Blood Demon Art gives him the power to alter his physical form. Like Gyutaro, he can craft living weapons from his own body. He can summon lethal, razor-sharp whips from his body. His manners are cold, calculating, and brutally efficient. Preferring strategy over direct confrontation, Muzan often deploys his minions to carry out his dark designs. However, when the situation demands, he can unveil a combat form of unmatched might, far surpassing the Upper Ranks in sheer force.
