The demons in Demon Slayer aren't your average boo scary monsters. These guys are walking natural disasters with insane powers, tragic backstories, and a serious hatred for sunlight. From the weakest Lower Moon to the all-powerful Muzan, each Demon brings something terrifying to the table.

But if we had to pick the top ten? That's where it gets tricky. But who are the strongest Demons in Demon Slayer? We're ranking these bloodthirsty beasts based on their powers, feats, and the hard time they have given to our heroes.

10/10 Kaigaku

Kaigaku used to be a Demon Slayer, just like Zenitsu. But when things got tough, he turned into a Demon instead of standing his ground. He became a replacement for Upper Moon 6 after Daki and Gyutaro died, and his Blood Demon Art is a twisted version of Thunder Breathing, with added demon powers.

Even though he was powerful, Kaigaku lacked true spirit, and Zenitsu, with all his doubts and fears, still managed to beat him. It’s ironic and satisfying to see Zenitsu rise above someone who once looked down on him. Kaigaku was strong, but not strong enough where it counted.

9/10 Daki

Daki is deadly, stylish, and too consumed with herself. She uses obi sashes that can slice through buildings, trap people, and move around like snakes. Her Blood Demon Art is both beautiful and terrifying. She caused chaos in the Entertainment District, giving a hard time to our heroes, especially Zenitsu and Inosuke.

But her biggest weakness is her overconfidence. Once the Demon Slayers figured out her connection to Gyutaro, she struggled to keep up. Without her, the Entertainment District Arc wouldn't have been a fan favorite. That alone makes her deserve a spot on this list.

8/10 Gyutaro

Gyutaro is the main muscle of the Demon siblings in the Entertainment District. With his poisoned sickles and insane speed, he has killed multiple Hashira and Demon Slayers. His Blood Demon Art lets him launch blood slashes that cut through anything.

Gyutaro is also incredibly durable, as he kept fighting even with his head nearly off. His bond with his sister Daki makes their duo even harder to deal with. If his neck wasn’t sliced at the same time as Daki’s, they would’ve kept regenerating forever. This unique trait, along with his strength, makes him one of the strongest Demons in Demon Slayer.

7/10 Gyokko

This guy has a weird obsession with art and turning people into art, literally. Gyokko hides inside creepy pots and moves around through them like portals. His Blood Demon Art allows him to summon deadly fish-like creatures and control water-based attacks.

He went up against Muichiro, the Mist Hashira, and even pushed him hard. But once Muichiro unlocked his mark, it was game over for Gyokko. Still, the way he fought and his bizarre abilities definitely make him one of the most unusual and strongest Demons in the show.

6/10 Hantengu

Hantengu is a very tricky Demon. He’s full of fear and runs away at the first sign of danger. But don’t be fooled - when he splits into clones, each one has a different personality with a very different and deadly power. It’s like fighting a whole squad of Demons at once.

His final form, called Zohakuten, controls wood dragons and giant attacks that crush everything. It took Tanjiro, Nezuko, and Genya all working together to beat him. Hantengu might look like a coward, but he’s seriously dangerous and super hard to kill.

5/10 Akaza

Unlike other Demons, Akaza is all about raw strength. He doesn't care about tricks or fancy techniques - he wants a straight-up fight. Akaza uses Destructive Death, a fighting style based on martial arts, and his blows hit like a truck. He also has one of the most emotional backstories in the series.

His fight with Rengoku is one of the best moments in Demon Slayer. Even though Rengoku was insanely strong, Akaza came out on top. But what really stands out is that Akaza regrets his actions. He’s not just a monster, but a tragic character who lost his way.

4/10 Doma

Don’t let the smile fool you - Doma is a cold-hearted monster. He hides behind charm and politeness, but he’s one of the cruelest Demons out there. His Blood Demon Art lets him create deadly ice attacks, and he can freeze his enemies in an instant.

He has killed multiple Hashira, and Kanae and Shinobu are two of them. Even during his fight with Inosuke and Kanao, it was only Shinobu’s poison inside his body that helped take him down. He’s the kind of villain who acts friendly while literally turning people into popsicles.

3/10 Kokushibo

Kokushibo is one of the most skilled swordsmen in the series, and the only Demon to use a Breathing Technique. He was once a Demon Slayer himself and the brother of Yoriichi, the strongest Demon Slayer ever. After becoming a Demon, he kept his sword skills and even developed a creepy blade made from his own flesh. No wonder he's one of the strongest Demons in Demon Slayer.

Kokushibo's attacks are wild and unpredictable, and his fight with Muichiro, Genya, Sanemi, and Gyomei was one of the toughest battles in the series. Even as he died, he looked terrifying - the dude had multiple eyes on his face, come on.

2/10 Muzan Kibutsuji

The original Demon King, Muzan, the one who started it all. He's been around for over a thousand years, creating Demons left and right, all while trying to become immortal. He can shapeshift, move faster than the eye can see, and heal from any injury almost instantly. He's basically a broken character with only one weakness, which is sunlight.

His Blood Demon Art is all about tentacle-like attacks that tear through everything. He can even split himself into tiny cells to avoid death. It took a whole army of Demon Slayers, all the Hashira, and a crazy amount of luck to finally bring him down. That tells you just how scary he was.

1/10 Demon King Tanjiro

Yes, you read that right. For a short moment, Tanjiro became the strongest Demon in Demon Slayer. After Muzan's death, his cells moved into Tanjiro’s body, turning our sweet boy into something terrifying. And the worst part? He was immune to sunlight, a weakness every other Demon had.

As the Demon King, Tanjiro was stronger than Muzan himself. His body could regenerate like crazy, and he was completely out of control. It took Nezuko and the others to snap him out of it, or else the world might’ve faced a new threat worse than Muzan. It was scary to see him like that, even for just a moment.
