From anti-magic rebels to time-controlling overlords is a must to watch. Black Clover’s most powerful devils form the underworld hierarchy.

Black Clover starts by providing us with context about a magical world where magic is everything. But the series took a massive turn by introducing devils with menacing presence. Think you’ve seen sinister villains before? Black Clover’s underworld offers something more than that. This dark fantasy world is the abode of some truly nightmarish devils. These malevolent beings from the underworld have been manipulating humans and threatening entire kingdoms. Some seek human destruction, others manipulate conflicts across generations, and a few even build unpredictable alliances.
Dive into the demonic hierarchy of devils that have proven themselves to be the stuff of nightmares in the Black Clover series. This list ranks the most powerful devils in Black Clover, analyzing their abilities, influence, and overall threat level.
1) Liebe

Abilities & Powers
- Anti-Magic
- Devil Union with Asta
- Strong Willpower
Starting the list of the most powerful devils in Black Clover is the underdog, Liebe. This devil seems to be at the bottom of our list, but his story loads an emotional punch. Like Asta, he was born without magic and was bullied and cast aside by other devils. As Asta’s devil partner residing in his five-leaf grimoire, Liebe’s Anti-magic powers let our favorite magicless hero cancel out magic attacks.
His backstory with Asta’s mother, Licita, forms a heart-wrenching connection in Black Clover. Despite being viewed as “lowest-ranked” among devils, Liebe has grown alongside Asta. His abilities are extremely broken when paired with Asta.
2) Zagred

Abilities and Powers
- Word Soul Magic
- High Intelligence
- Immense Durability
Zagreb was the first high-ranking devil introduced in Black Clover. He was the one who kicked off the major devil plotline in the series. He is also known as the Word Magic Devil and earns his place among the most powerful devils in Black Clover via his manipulative genius. This cunning fiend planned events spanning five centuries to manifest in the human world!
Zagred’s Word Magic is downright terrifying, capable of dominating entire battles with his voice. It allows him to make anything he says into reality. If you want to summon a storm of swords, speak it into existence! He nearly succeeded in obtaining the five-leaf grimoire and would’ve caused unprecedented chaos if not for the combined efforts of multiple Magic Knight captains and even the first Wizard King himself.
3) Nahamah and Lilith

Abilities & Power
- Fire and Ice Magic
- Fusion Form
- Extreme Sadism
The twin supreme devils Nahamah and Lilith form a serious power residing among the most powerful devils in Black Clover. These siblings operate as a devastating tag team with complementary magical abilities that make them twice as dangerous. Nahamah wields Ice Magic so cold it can freeze even magic, while Lilith controls Fire Magic hot enough to burn through anything in its path.
In Black Clover, they are the rulers of the first level of the underworld. Their innate regeneration abilities make them nearly impossible to kill through conventional means. It took Nacht using his devil union mode and Asta pushing his limits to take them down. Even then, their defeat came only after they merged into a single entity of absolute destruction.
4) Baal

Abilities & Powers
- Atmosphere Magic
- Weather Manipulation
- Raw Speed and Power
Baal proves that elemental mastery can be utterly devastating to the most powerful devils in Black Clover. He is the ruler of the second level of the underworld and commands Atmospheric Magic with precision and power. His storms can cover entire battlefields and strike with pinpoint accuracy.
His atmospheric actions come at a speed almost impossible to dodge. Even his ability to manifest multiple lightning constructs simultaneously makes him impossible to approach. As reincarnated as a paladin, he can cast his strongest spells, hinting at the magic knowledge from the dawn of time. Baal is the perfect storm of ancient wisdom and overwhelming lightning power.
5) Megicula

Abilities & Power
- Curse Magic
- Regeneration and Immortality
- Control over Vanica
Maybe only a few devils have caused as much personal suffering as Megicula. It has earned her a feared spot among the most powerful devils in Black Clover. Her cunning evilness specializes in Curse-Warding Magic. This magic allows her to put deadly curses on humans that are nearly impossible to break. Her most notorious curse affected an entire country, killing anyone who mentioned the word “love.”
She spent years planning her full manifestation in the human world via Vanica Zogratis. Her curses affected major characters like Noelle’s mother—Acier Silva and the Heart Kingdom’s princess—Lolopechka. Additionally, these curses lead to the downfall of many powerful figures in the series. Even a partial manifestation of her power could challenge multiple captains altogether! She can easily adapt and evolve during battle due to her countermeasures against almost any magic type.
6) Beelzebub

Abilities & Power
- Spatial Magic
- Absolute Control
- Host of Zenon Zogratis
The mastermind of spatial dominance, Beelzebub ranks high among the most powerful devils in Black Clover as the ruler of the third level of the underworld. His Spatial Magic lets him distort reality and form gates between dimensions while trapping enemies in inescapable pocket dimensions.
Beelzebub’s influence grows across the entire Black Clover storyline, as his spatial gates enable other devils to enter the human world. He has the magic power to reshape the entire battlefield. Considering the strongest spatial magic users in the human realm, they are like a small pebble in the roadside to this devil.
7) Lucifero

Abilities & Power
- Gravity Magic
- Demonic Strength
- Overwhelming Presence
Lucifero is nearly unstoppable and unpredictable when it comes down to the most powerful devils in Black Clover. He is the ruler of the seventh and lowest level of the underworld. His Gravity Magic exerts pressure so intense it can flatten mountains and crush armies without a sweat. His presence is enough to create suffocating gravity that brings even the strongest Magic Knights to their knees.
Lucifero’s physical strength is the perfect match for his magical abilities, allowing him to battle even against the anti-magic of Asta with raw force. The terror Lucifero inspires isn’t just from his overwhelming power but from his cold hatred. His defeat came only with nearly every major character teaming up against him.
8) Astaroth

Abilities & Power
- Time Magic
- Absolute Domination
- Unmatched Intelligence
The most powerful devil in Black Clover is the enigmatic Time Devil, Astaroth. Even though he has been into less direct combat compared to others, his expertise over time places him at the absolute peak of the devil hierarchy. Astaroth’s Time Magic allows him to manipulate the most fundamental force in existence—something that affects everything and everyone.
He can accelerate, slow, stop, or even reverse time within his sphere of influence. This ability connects to some of the series’ biggest mysteries, including Julius Novachrono’s time magic and the destruction of an entire race. Among all the most powerful devils in Black Clover, Astaroth is the ultimate threat. No enemy stands a chance when time is against them.
Conclusion
The devils in Black Clover are villains with involved entities depicting different forms of existential threat. Their powers are the different facets of animosity and destruction. Some of them manipulate from the shadows, others crush with overwhelming force, but all have left their curse mark on the series.
