KonoSuba - God's Blessing on this Wonderful World is one of the funniest isekai animes out there. It features one of the best main characters in isekai in Kazuma Satou, a carefree character who would rather run from his responsibilities than face him. With friends like Darkness, Megumin, and Aqua, it's not hard to see why. The world of KonoSuba is filled with powerful enemies, great magical abilites, and some of the strongest characters around. While Kazuma and his party have defeated most of the Devil King's Generals, there are still a few evil-ish characters lying around that might cause them trouble.

While KonoSuba isn't a series that focuses on power or strength, there are still a handful of characters who stand out for their incredible abilities. KonoSuba easily ranks among the best fantasy isekai anime of all time, so it's no wonder that some of its characters would possess some truly powerful magic.

10 Iris Stylish-Sword Belzerg

The First Princess Has Divine Treasures Galore

As the First Princess of Belzerg, Iris has a ton of powerful divine treasures at her fingertips. Her royal family is responsible for summoning heroes like Kazuma to her world, and when they come, they usually arrive with powerful Cheats given to them by Aqua. Her Something-Calibur sword is one of the strongest in the series, protecting her from any debuffs that could come her way. She also has the Sacred Lightning Blare, which summons a powerful bolt of lightning and a gust of wind strong enough to mow down an army of golems.

While Iris is still only a 12-year-old-girl, she's had some of the best training her world can offer her since she was an infant. She's now level 60 and has the equipment to back her power up. When she's fully grown, she'll be able to get the most out of her Divine Treasures and defeat almost any enemy that comes her way.

9 Eris/Chris

The Goddess of Luck

Eris hasn't had a chance to put most of her godly powers on display, but she doesn't really need to. As the Goddess of Luck, she controls her life with ease. She can see everything that happens in the world beneath her, can stop herself from aging, and has even brought Kazuma back to life on multiple occasions. When she comes to the mortal world, she does so as a thief named Chris. Her luck skill is so high as a mortal that her adventurer card glitches out when it tries to display it.

As a Goddess, Eris has access to Holy Magic that can both buff her allies and debuff her enemies. Some of her strongest buffs include Haste, which improves speed, Powered, which increases strength, and Blessing, which increases luck. While Eris might not have a limit as to how many times she can revive Kazuma, she might get tired of bringing the clumsy character back to life so many times.

8 Kyouya Mitsurugi

The Wielder of the Cursed Sword Gram

If Kazuma Satou is a hero reincarnated into a new world with an absurdly high luck stat, Kyouya Mitsurugi is the opposite. He's a traditional soldier-looking character who wields one of the most powerful swords in the series in the Cursed Sword Gram. The Cursed Sword Gram is a Divine Treasure given to Mitsurugi by Aqua. It has the unique ability to cut through any material, and because it's a powerful sword that chooses its master, only Mitsurugi can use it.

Mitsurugi's class is sword-master, allowing him to use the powerful Rune of Saber ability to cut through his opponents magically as well as physically. Unfortunately for Mitsurugi, Kazuma has his number. Kazuma is always getting the upperhand over Mitsurugi, either stealing his powerful Sword or freezing him in place against the sword-s will to defeat him easily.

7 Kazuma Satou

The Luckiest Adventurer in Belzerg

Kazuma Satou doesn't appear to be a strong character in KonoSuba on his surface. He's a scrawny, timid hero who wants nothing to do with the responsibilities thrust upon him. While he might not have the ability to defeat his opponents in a single blow like Aqua, he's one of the smartest isekai main characters around, and he's always one or two ideas away from winning a fight. His snipe skill is one of his best, allowing Kazuma to draw his bow back and send a lethal arrow at his opponents.

Outside of archery, Kazuma is a great Thief-Class character who can steal important items from his enemies in the heat of battle. He even uses his opponent's knowledge of his Steal skill to trick them into letting their guard down, as he fakes a Steal only to Freeze his opponents. With Darkness, Aqua, and Megumin with him, Kazuma is almost unkillable. Thankfully, if he does die, Eris will give him another chance.

6 Wiz

The Ice Witch of the Devil King's Army

Wiz is an immortal Lich in KonoSuba, but she doesn't appear that way. Wiz looks like a normal, kind lady who runs a simple shop in Axel. In reality, she was one of the Devil King's Generals in his army, earning the formidable moniker of Ice Witch during her time. As an undead Lich, Wiz has access to a litany of undead abilites that give her a ton of power. One of her most powerful abilities is Drain Touch, where she can drain the life force from her target and add it to her own simply by touching them.

She can also use teleportation to teleport herself and her allies a great distance. Her abilites to create golems and mud walls are always helpful in battle too. Wiz can also use the Advanced Magic spell Bottomless Swamp to trap her opponents in a deep, gooey mess that makes them vulnerable to all types of attacks.

5 Yunyun

An Advanced Magic Master

Yunyun would be a great help to Kazuma's party if he let her in. If it wasn't for Megumin's Explosion magic, Yunyun would probably be the most powerful Crimson Demon there is. Yunyun knows three tiers of magic and can use them all effectively. She can create a stream of clean water through her Basic Magic, can shoot giant fireballs with her Intermediate Magic, and can even cast some of the most powerful spells in the series with her Advanced Magic.

Even though Yunyun is one of the most powerful characters in the series, she can still get embarrassed. One of the funniest moments in KonoSuba happens when Yunyun is with her rival Megumin in Wiz's shop. They use one of her artifacts to try and mend their friendships, only to expose their embarressing pasts to all of Megumin's allies.

4 Megumin

Megumin Can Use the Most Powerful Magic in KonoSuba

Megumin is one of the few s of one of the most powerful magical abilites in KonoSuba. Her Explosion magic is feared by all, giving her the power to create a single explosion of nearly immeasurable power where she chooses. It's so powerful that once she casts it, she nearly es out due to exhaustion, forcing one of her party to carry her back home. She's her party's biggest weapon due to a single spell. While she's incredible on the offensive front, her defensive abilites are lacking, yet again forcing her teammates to compensate for her.

But that's what a team is for, as Darkness' hyper-defensiveness is only complimented by Megumin's purely-offensive Explosion Magic. As a Crimson Demon, Megumin has extemely high levels of intellect and has access to an immense pool of mana as well.

3 Aqua

A Water Goddess With God-Tier Punches

Aqua is one of the funniest characters in KonoSuba, and that's not a small feat considering the series is highlighting how great KonoSuba's art style and direction are.

She specializes in healing her allies, ing them through powerful buffs, and the best anti-demon magic in the series. Her two strongest god moves are God Blow and God Requiem. God Blow is a powerful punch Aqua throws with all of her rage and sadness behind it. It can purify demons and the undead in an instant, just like her God Requiem. The Requiem is a hook variant of the God Blow, where Aqua transfers her love and sorrow into her opponent with a decicive strike.

2 Maxwell

One of the Seven Archdemons of Hell

Maxwell is a mysterious character in season two of KonoSuba. He was the Arch-Duke of Hell powerful enough to manipulate the events of the series behind the scenes. When Vanir finds him, he's able to release his fellow lord of the underworld from his captivity. Maxwell is known as the "Warper of Truth", with his powers allowing him to reshape reality itself. His Powers of Adjustment give him the ability to adjust people's perception, making them think events are happening that simply aren't.

He's also capable of casting powerful curses. His curses are so strong even the strongest priests can't break them and it takes a living god in Aqua to take them apart. Maxwell is an aloof character and that's probably for the best. His ability to rewrite the world around him is easily one of the strongest in the series.

1 Vanir

Rumored To Be Stronger Than the Devil King Himself

Vanir is easily the strongest character in KonoSuba, and it's not even close. He's a former General of the Devil King's army and one of the few Arch Dukes of Hell. He's been rumored by the Devil King's own army to be stronger than the Devil King himself and it's easy to see why. Vanir is incredibly smart, manipulative, and has some of the most overpowered abilites in the series. He can look into people's minds and see both the future and the past, can possess people if they wear his mask, and can create spare bodies out of the dirt in front of him.

He also has a bunch of Vanir-Style moves that can instantly kill his opponents, so long as they're not Wiz or Darkness. His Vanir-Style abilites include the Murder Ray, Eye Beam, and Destruction Ray. Kazuma and his party were lucky to kill the Arch Duke the first time, and thankfully, he seems to be fighting for KonoSuba's good guys, at least for now.
