Knighthood has always been a highly respected title, as anyone can wield a sword or wear a suit of armor, but it takes a special kind of strength both physically and in character to truly be considered a knight. There have been plenty of knights in anime, all as unique as they are strong, and it's not just a title for the men either.
Across many titles, anime has seen its fair share of female knights, powerful both in body and in spirit. These female warriors are truly knights among knights, with some insane feats of strength that could make whole armies quake in their boots at the very sight of them.
10 Darkness' Aim May Be Terrible, But She Has Strength And Stamina To Last (KonoSuba)
Darkness (aka Dustiness Ford Lalatina) is KonoSuba's resident crusader and one of the many weirdos that occupy Kazuma's party. She can't aim her sword at all, missing almost anything she tries to swing at, and masochistic personality gets her into some pretty rough situations, not that she seems to mind, though.
Despite being absolutely terrible in a fight, Darkness is no slouch in strength, stamina, and durability. Her defense against magic protects her from almost all status ailments, and she's even been able to survive the full force of one of Megumin's explosions. Darkness may be many things, but weak isn't one of them.
9 Alice, One Knight That's Worth Hundreds (Sword Art Online)
Armed with the best weapons and armor, the Sword Art Online's Integrity Knights are some of the most powerful warriors that Underworld has to offer. Physically stronger than the average human and proficient in magical arts, just one Integrity Knight is worth entire armies of soldiers, and Alice Zuberg is no exception.
Unlike Kirito's other allies, Alice is an AI who's spent her life training to become the best of the best, and the results are nothing to sneeze at. Able to split her sword into multiple smaller ones, Alice is capable of chopping down a whole forest in almost no time and devastating a canyon full of enemies.
8 Alisha Is The Princess Knight Of Hyland (Tales Of Zestiria The X)
Alisha Diphda is a princess of Hyland, but not one next in line for the throne. As such, Alisha found other ways to serve her kingdom by becoming a knight. As the story of Tales of Zestiria goes on, Alisha eventually becomes an ally to the Sheperd Sorey. Skilled in both magic and spear combat, Alisha walks into battle prepared for anything.
Thanks to her status as a Sheperd's squire, Alisha is also able to use Armatization to transform into new forms with the power of the Seraphs, greatly increasing her physical capabilities and magical abilities far beyond the limits of normal people.
7 Clare Is Capable Of Taking As Many Hits As She Can Dish Out (Claymore)
Claymore's Organization has created many human-monster hybrids (known as "Claymores") to combat the Yoma threat, but Clare is among the best of them. Despite being ranked at number forty-seven, Clare's strength grew exponentially to the point where she's turned defeated plenty of Yoma and even other Claymores into minced meat.
Clare is able to enhance her strength with Yoki (demon energy), heal through regeneration, and transform into a more powerful half-Yoma form. Clare has stood on equal footing with the Organization's most destructive Claymores, such as Miria (who has defeated an entire generation's worth of Claymores) and even defeated Pricilla (the number two Claymore who shirked off attacks from the Destroyer).
6 Diane, The Serpent's Sin Of Envy With A Giant Personality (Seven Deadly Sins)
The Seven Deadly Sins' namesake band of knights is a powerful collection of misfit warriors known to be the strongest in the kingdom of Liones. One such member is Diane, the "Serpent's Sin of Envy," a giant who can bend the earth itself to her will.
Diane's large size is matched by her natural strength, unwavering loyalty, and sheer magical power. Wielding the massive hammer, Gideon, Diane's capable of bringing out her full capabilities, such as turning her body to metal, creating weapons from the ground, fighting golems, shields of diamond, and can even punch out enormous chunks of earth to attack with.
5 Erza's Not Called The "Fairy Queen" For Nothing (Fairy Tail)
Also referred to as "Fairy Queen Titania," Erza Scarlet is the resident armor-clad mage of the Fairy Tail Guild and is one of its strongest members. She possesses a strong will and a strong body that's capable of pushing past its limits. Erza is capable of using her version of Requip Magic ("The Knight") to use various different armors and weapons, each with its own unique and powerful abilities.
Erza has matched enemies that could devastate whole cities, taken blows from Gray and Natsu at their best, and even once destroyed a powerful meteor-like spell. Time and time again, Erza stands tall as one of the strongest and boldest of Fairy Tail's cast, and she was even Fairy Tail's Guild Master for a time.
4 Charlotte, Captain Of The Clover Kingdom's Blue Rose Knights (Black Clover)
Black Clover's Clover Kingdom is home to the Magic Knights, divided into nine different squads and devoted to defending their country. One squad is the Blue Roses, a team mostly made up of strong and spirited women led by their captain Charlotte Roselei. Disciplined and composed almost to a fault, Charlotte has an immense magic power that's complemented by her skills in combat and her mastery of Briar Magic.
Able to create vines, weapons, and mess with an opponent's senses, Charlotte's magic is as strong as it is adaptable, and her power has only increased thanks to the Mana Method. She's especially powerful against cursed enemies, particularly her "Queen of Briars" form, which becomes more powerful depending on the curse.
3 Apollonia, The Infamous Black Knight Feared Across The Sky (Granblue Fantasy The Animation)
Granblue Fantasy's Seven Luminary Knights are warriors that serve the mysterious True King and are each powerful enough to pass through the Grim Basin (violent wind barriers that would tear anyone else to shreds) with ease. Among them is a top official of the tyrannical Erste Empire, Apollonia feared across the skies as the Black Knight.
With or without her armor, Apollonia is stronger and faster than the average human, and with her sword Blutgang, she can even drain the life force from her opponents. Like the rest of the Luminary Knights, Apollonia is capable of not only tanking hits from Primal Beasts (who wield almost god-like power) absorbing them and using their powers too.
2 Merlin Is One Of The Sins' Strongest Members, Both A Knight And A Mage (Seven Deadly Sins)
Merlin is another member of Seven Deadly Sins' gang of powerful knights, though she also doubles as a mage, and a very powerful one at that. Equally as intelligent as she is strong in the ways of magic, Merlin has been able to shrug off attacks and spells that would've killed a normal human ten times over, and she can dish it back out just as hard.
Able to manipulate various elemental magic, amp her or her allies' power, make her spells last an eternity, cancel out any spell she chooses, and even stop time itself, Merlin's power is almost limitless. Even the mere mention of her name has terrified powerful demons in the Ten Commandments.
1 Saber Is As Powerful As She Is Noble (Fate Series)
The Fate series has seen many heroic spirits with insane levels of power, though few are as powerful or as popular as Artoria Pendragon (aka Saber). Saber's instincts and reaction time as sharp as her sword, with durability that's allowed her to withstand and trade blows with Berserkers, and she has defeated servants that had power capable of destroying the entire world.
With her Noble Phantasms, Excalibur is able to easily slice through other Noble Phantasms and even instantly kill servants hit by it. In addition, Avalon not only gives Saber regeneration and immortality, but it also acts as an impenetrable shield that can stop anything. Saber's full power is practically unfathomable, a true "King of Knights."
