The Seven Deadly Sins is filled with overpowered characters that possess limitless reserves of strength, varying degrees of immortality, and powerful magical abilities that make it difficult for any of them to fall in battle. Most of the series' strongest characters belong to the Seven Deadly Sins or the Demon Clan, and while there are other powerful characters, like many of the Holy Knights that serve the kingdom of Liones, they often aren't given the credit they deserve.

While all the Sins were formerly acknowledged as Holy Knights, they're very different from the normal batch of human Holy Knights whose abilities just can't compare to theirs. The series has introduced so many Holy Knights that it's impossible to keep track of them all, but thanks to the tangible power levels that every character possesses, it's easy to see which ones are truly the cream of the crop.

10 Guila (1,350)

Guila casting Explosion - Seven Deadly Sins

As one of the New Generation Holy Knights, Guila played a prominent role in the first season of The Seven Deadly Sins, at one point attempting to kill Meliodas and his friends as she had been ordered to. She's a complete professional, barely breaking her composure even when the odds were stacked against her.

She managed to fight Diane, Meliodas, and Ban at the same time, using her magical ability, Explosion, to get around the advantages that the Sins normally had against other human Holy Knights.

9 Griamore (1,520)

Griamore using his Wall ability - Seven Deadly Sins

Size doesn't matter in The Seven Deadly Sins. Diane may be the largest Sin, but she's far from the strongest. Likewise, Griamore's foreboding physique doesn't make him nearly as strong as some of his more petite comrades. The secret to his strength actually lies in his magical ability, Wall, which enables him to create resilient barriers around either himself or his enemies.

His Perfect Shell, an extension of this ability, was strong enough to trap a Red Demon's flame attack, preventing it from exiting the creature's mouth and instead detonating at point-blank range, wounding the Demon. His barrier was strong enough to defend against a Gray Demon's Dark Nebula attack, which managed to reduce everything else in the vicinity to dust.

8 Deathpierce (1,690)

Deathpierce In The Seven Deadly Sins

As a member of the elite Holy Knight group known as the Pleiades of the Azure Sky, Deathpiece definitely has more experience than the average Holy Knight. His magical ability, Melody, allows him to delay any magical attack cast in his presence. Once these spells are cast, he can even alter their movements, making them veer off course.

He first used this ability to support Denzel Liones during his fight against Fraudrin, and if it weren't for Grayroad of Pacifism being there to prevent the fight from continuing, Deathpiece's overpowered ability would've given Denzel the opening he needed to land a decisive strike.

7 Gilthunder (2,330)

As the son of Zaratras, Gilthunder is destined to be a great leader. Even when many of the other Holy Knights followed Hendrickson's evil agenda without question, Gilthunder only did so to protect the woman he loved. His ability to enhance his attacks and movement with lightning magic made him a hard hitter and made his hits harder to even anticipate long before his training in Istar.

When he and Meliodas fought Hendrickson together, Gilthunder overwhelmed his opponent with a barrage of critical strikes despite Hendrickson's own power being leagues above his own. It's no surprise why he was chosen to accompany the likes of Escanor, Merlin, and Ludocel when they went to infiltrate Camelot during the Second Holy War. He might not be the strongest Holy Knight around, but his experience and leadership will always enable him to prevail against opponents that possess more power than he does.

6 Howzer (2,350)

Howzer and Gilthunder are somewhat like rivals, despite how different they are personality-wise. While Gilthunder has a tendency to remain calm and introspective, Howzer can be naive and full of himself. And yet he has the strength to back this side of his personality up. After training in Istar, he became a bit stronger than Gilthunder while also strengthening his magical ability, Tempest, which allows him to control the wind.

Despite not feeling that he was fit for the role as a Great Holy Knight, the title suits him well, evident by the way he led the Holy Knights of Liones headfirst into a Demon army without hesitation.

5 Hendrickson (2,650)

Hendrickson fighting - Seven Deadly Sins

Hendrickson's power skyrocketed when he became a Gray Demon, but even without these powers, he remains one of the strongest Holy Knights in all of Liones. One of his magical abilities, Purge, enables him to kill lesser demons with a single touch, and even force certain demons or even angels out of bodies that they possessed, a skill that's definitely been useful as the Second Holy War reaches its climax.

His age has caught up with him and he's far from what he used to be in his younger years, but that doesn't stop him from being the first one to charge into a fight.

4 Slader (2,790)

Slader takes down Meliodas - Seven Deadly Sins

Slader was the captain of the infamous Holy Knight group known as the Dawn Roar.  When he and Meliodas clashed for the first time, even Meliodas was intimidated by Slader's strength. His magical ability, Overpower, lives up to its namesake, enabling him to overwhelm his enemies and immobilize them long enough to give him the upper hand.

In the manga, he used this ability to break Gowther's neck; if Gowther wasn't a doll, this would've won him the fight. When he aligned with the Sins, he became a worthy ally and a pretty cool guy to be around despite his intimidating mask and huge gigantic sword that makes him always look like a deranged murderer.

3 Denzel Liones (2,870)

Denzel Liones Casting Judgment - Seven Deadly Sins

As Captain of the Pleiades of the Azure Sky, Denzel Liones was no joke. His magical ability, Judgment, is disastrous against those who have taken many lives. Once he marks his target, the souls of the victims that the target has killed begin to torment them until they suffer the same fate. Against Fraudrin, this attack brought him to his knees.

Denzel is a master swordsman, able to go head-to-head with Fraudrin with minimal aid, but his key ace in the hole was his sword that enabled him to be possessed by a Goddess, although this didn't do much against the Ten Commandments' Derieri.

2 Dreyfus (3,000)

It's unfortunate that Dreyfus was possessed by Fraudrin for so long since he was already strong enough on his own. His Break ability enabled him to resist the magic of others with his willpower alone. It was strong enough to break through Diane's attacks when the two first encountered one another in the royal capital of Liones.

Extensions of this ability enabled him to fire off piercing waves of energy from his sword that few could stand up to. Even after recovering from his Star Breaker attack, Fraudrin admitted that this move would've annihilated him had he not been at his full power.

1 Zaratras (3,060)

Zaratras arrives on the battlefield - Seven Deadly Sins

Not only did Zaratras possess Hendrick's Purge ability, being a descendant of Druids, but he could also command lightning, similar to his son Gilthunder, only to a greater extent. This is what enabled him to land a decisive blow against Fraudrin when few others could. While the Goddess Nerobasta was unable to withstand a direct hit from Derieri, Zaratras managed to withstand one of her blows at the cost of his shield.

Unfortunately, he threw away the second chance at life he'd been given in order to Purge Fraudrin from Dreyfus's body, so viewers won't be able to see the absolute limits of his power in future Seven Deadly Sins content.
