In the mega-popular anime series Black Clover, magic is the source of the character's power. Depending on which grimoire a character possesses, they will be granted special magical powers and unique abilities that give them a leg up on their competition. While the antagonists of the Dark Triad and the Spade Kingdom possess omnipotent superpowers, they often pale in comparison to Asta and some of the main characters fighting on behalf of the Clover Kingdom.
Whether it's Asta, Yuno, Noelle, Julius, the Vermillions family, or some of the others, the most formidable main characters in Black Clover have impressive skillsets that are not to be trifled with.
Yuno
As Asta's most trusted foster brother and protective sidekick on the popular demon-slaying anime, Yuno makes up for Asta's lack of magical power through his unique abilities. Thanks to his four-leaf grimoire and half-elf possession, Yuno can wield Wind Magic, Creation Magic, Spirit Magic, Star Magic which enables him to manipulate the cosmos, create deadly objects out of thin air, and more.
Yuno bolsters his power by using Spirit Magic to summon Sylph, a wind spirit that can help him fight battles. When channeling 100% of Sylph's energy, Yuno obtains enough mana to reach Saint-Stage, the highest form of devil-abolishing magic.
Noelle Silva
As a Royal Member of House Silva, Noelle Silva is one of the most formidable main characters due to her immensely powerful Water Magic, which she can use to create and control real water, launch deadly water balls at her foes, and conjure giant lethal aqueous entities in a flash.
What's more, Noelle significantly increases her overall prowess once she is possessed by Undine, the almighty water spirit. When Noelle harnesses Undine's power, she becomes a Saint-Stage mage strong enough to defeat most elves with extremely potent offensive curses.
Lolopechka
Also bolstered by the immense power of the Water spirit Undine, Lolopechka reigns supreme as the Princess of the Heart Kingdom. She slightly bests Noelle due to the healing powers she possesses in conjunction with Water Magic, Spirit Magic, and most impressive, Dark Water Magic. As a princess and priestess, Lolopechka can access all of the knowledge and abilities of her predecessors.
Lolopechka also controls all of the mana in the Heart Kingdom and becomes even more powerful when Megicula alters her curse and grants her the extremely awesome offensive powers that come with her Dark Water Magic upgrade.
Fuegoleon Vermillion
Due to his royal nature as the first son of Clover Kingdom's House Vermillion, Fuegolion comes from a supremely powerful bloodline of main characters on the beloved demon anime series. The almighty captain of the Crimson Squad is a master of Fire Magic, which he can manipulate and conjure incendiary objects to fight with.
With supreme strength, strategy, and skills, Fuegoleon was able to defeat such formidable foes as Rades Spirito, Elf, and the Apostle of Sephirah fairly easily in one-on-one battles. Fuegoleon can also increase his overall power by summoning Salamander, the fire spirit.
Yami Sukehiro
The unmistakable first captain of the Black Bull squad in the Clover Kingdom, Yami Sukehiro is one of the strongest main characters on the stellar horror anime series. He uses a rare form of Dark Magic that bends darkness and absorbs Light Magic, which is so immense that can affect other worlds. As a result, Yami has been deemed an Arcane-Stage mage.
In addition to having the almighty skills to create black holes, Yami's reinforcement magic is so severe that he can withstand the sinister Devil Dante's Gravity Magic spells. Moreover, Yami possesses inherent Ki, a sixth sense that allows him to react before his opponents.
Mereoleona Vermillion
Fuegoleon's older sister, Mereoleona Vermillion, is one of the strongest female characters in any animated TV show. The eldest daughter in the Vermillion royal house and one-time Crimson Squad leader, Mereleona has all the magical powers of her brother and then some.
The masterful Fire magician can turn licks of flames into a giant lion's claw that she uses to rip enemies apart. If that move fails, Mereoleona will simply outmuscle her foes with her combat expertise, ability to create a lava-based forcefield around herself during attacks, and superior strength, speed, and endurance. Hailed as the strongest human in the Clover Kingdom, Mereoleona is even strong enough to pierce Asta's Demon-Slaying Sword.
Julius Novacrhono
As the Magic Emperor of the Clover Kingdom, Julius Novachrono is a difficult main character to defeat. Julius not only leads every squad in the protection of the kingdom, but he also possesses a rare form of Time Magic that gives him a huge advantage. Playing God, Julius can speed, slow, stop, and even reverse temporality.
Julius also possesses Transformation Magic, which allows him to turn into any person he desires, which gives him a huge advantage in tricking enemies. With unparalleled speed to boot, which allowed him to outrace Patolli, Julius earns his title as Emperor.
Licht
Before turning himself into a demon following the Elf Tribe Massacre, Licht was a good-hearted main character with superior skills and supernatural abilities. He draws much of his strength from Sword Magic, which creates the unparalleled Demon-Slayer Sword, Demon-Dweller Sword, and Demon-Destroyer Sword, three of the mightiest weapons in the show.
Licht can also use Union Magic to combine his Sword Magic with other forms, thereby increasing his overall prowess. Licht can also wield Forbidden Magic, which allows him to draw energy from the underworld.
Lemiel Silvamillion Clover
As the first Magic Emperor of Clover Kingdom's Magic Knights Squad, Lemiel Silvamillion Clover is the most powerful main character other than Asta. With his trademark Light Magic, Lemiel can cast spells strong enough to defeat curses cast by Licht's demon form. He can also conjure swords made of light and forms arrows of light on which he can travel a great distance.
When harnessing all of his magical powers at once, Lemiel was able to defeat the almighty devil Zagred, proving his supremacy as a human royal with more inherent mana than anyone in his kingdom.
Asta
As the main protagonist on the show and future Emperor of the Clover Kingdom, Asta is easily the most powerful character on the show. Defined by his Anti-Magic skills which enable him to nullify every single other character's supernatural attacks, Asta is a uniquely talented warrior who will outwit and overpower his opponents through speed, swordsmanship, strategy, intellect, and his sixth-sense Ki.
Moreover, when Asta is in devil form under the possession of Liebe, he has access to an omnipotent 5-leaf grimoire that allows him to neutralize Gravity Singularity and add additional weapons to his arsenal. Best of all, Asta's four Anti-Magic swords, including Yami's Demon-Slasher Katana, are the most powerful weapons in Black Clover.
