The original demon and main antagonist, Muzan is easily the most powerful. With near-immortality, shapeshifting, regeneration, and control over all demons, he's a true nightmare. His blood can create new demons or destroy them, and his speed and strength outmatch even the Hashira.
Kokushibo

A former Demon Slayer who became a demon, Kokushibo has both breathing techniques and Blood Demon Art. His Moon Breathing combined with swordsmanship, regeneration, and combat IQ make him the most dangerous of the Upper Moons.
Akaza

A fan-favourite and martial arts powerhouse, Akaza specialises in hand-to-hand combat. His Destructive Death style and ability to sense "fighting spirit" make him a lethal close-range opponent. His emotional backstory only adds to his complex strength.
Doma

Doma's calm smile hides his terrifying power. With deadly ice-based Blood Demon Art and emotional detachment, he absorbs his enemies with a chilling grace. He killed several key characters, proving his threat level.

Known for splitting into multiple powerful clones, each with a distinct ability and emotion. Anger, Pleasure, Sadness, and more. His final form, Zohakuten, is a massive threat capable of battling multiple Hashira-level opponents.
Gyokko

An eerie demon with a grotesque appearance, Gyokko's powers revolve around manipulating vases and summoning deadly fish-like creatures. His regeneration and creativity in combat make him hard to predict.
Kaigaku
Souurce: Kimetsu no Yaiba Wiki
Zenitsu's former peer, Kaigaku became a demon and inherited some of Kokushibo's power. He uses lightning techniques corrupted by demonic energy, making him fast and unpredictable, though emotionally unstable.
Rui

Though weaker than the Upper Moons, Rui left a massive impact early in the series. His Blood Demon Art using threads is brutal and precise. He nearly killed Tanjiro and Nezuko despite his lower rank.
Enmu

The villain of the Mugen Train arc, Enmu uses sleep-based abilities to trap victims in dreams.
Though not physically strong, his psychological warfare and manipulation earned him the top rank among the Lower Moons.
Nakime

After gaining Upper Moon rank post-Nakime's promotion, she could manipulate space within the Infinity Castle. Though not a frontline fighter, her spatial abilities made her essential to Muzan's control and defence strategy.
From ice-wielders to sleep-manipulators, the Demon Slayer universe has no shortage of terrifying demons. Each one brings more than brute force, they challenge the emotional and moral strength of our heroes. Stay tuned as more anime arcs unveil even greater threats!
