Yoru. Kokuto Yoru (aka Black Blade Yoru) is currently the strongest sword in One Piece. It is befittingly in the hands of the greatest swordsman in the world, Dracule Mihawk. Yoru is graded as one of the 12 Supreme Grade swords, the highest quality swords ever created in the One Piece universe.
The strongest of these swords are the Wado Ichimonji, Shusui, and Enma. Wado Ichimonji is Zoro's most treasured weapon as it was been given to him by his master after his childhood friend and greatest rival's untimely death.
Zoro usually carries three swords with him to perform the three-sword style anytime. So currently, he has the Wado Ichimonji, Kitetsu III, and Enma with him.
Points: Zoro 1, Law 0 Devil Fruit Roronoa Zoro is a very powerful character. He is known as one of the most powerful characters in the series and one of the series' best swordsmen; he is, by all means, probably going to surpass even Mihawk in the future.
Who is Zoro's father? Roronoa Arashi is confirmed to be the father of our beloved swordsman, Roronoa Zoro.
Shusui is another legendary blade from Wano, which Zoro found during the Thriller Bark arc. It belonged to a spectacular swordsman called Shimotsuki Ryuma, and people revered it as a national treasure. The sword has an iconic black blade, indicating its strength and rarity.
As one of the 50 Skillful Grade Swords, Yubashiri was a rare and reliable weapon that served Zoro's unique fighting style well. It was destroyed during Zoro's fight with Shu on Enies Lobby, and was later left alongside the Rumbar Pirates' gravesite on Thriller Bark.
Eclipsing Zoro in both mastery of Armament and Conqueror's Haki, Luffy proves himself stronger than Zoro overall. While Zoro does edge out a victory in terms of strength and physical endurance, Armament and Conqueror's Haki are undoubtedly the two more relevant factors here.
Being of the lowest grade of the three swords, Sandai Kitetsu is the weakest of all the Kitetsu swords. Its name also indicates it was the last of the three to be made. The panel of Zoro keeping Sandai Kitetsu in the manga is extremely similar to that of Zoro keeping Enma.
He uses the Nidai Kitetsu when he faces Basil Hawkins, to which Luffy threw a punch with the sword in his hand. The Nidai Kitetsu (trans. "Second Generation Ogre") is a cursed sword that supposedly brings a horrible death to its users.
Shimotsuki Ryuma was a legendary, world-famous samurai hailing from the Shimotsuki Family of Wano Country, who lived during Wano's "Country of Gold" era centuries ago. He was revered for his mastery of swordsmanship that earned him the title Sword God, as well as his feat of slaying a dragon.
Zoro x Hiyori
They shared intimate moments and Zoro might even find a sense of belongingness when he's with her. Throughout his tedious journey, Zoro met a lot of potential partners but the connection he seems to have with Hiyori seems special as Wanokuni has immense influence over Zoro's life.
Zoro & Chopper's Strong Bond
Their intricate relationship is more akin to blood brothers. In this type of relationship, the elder brother usually looks out for the younger brother, while the younger uses him as a role model. In other words, Zoro looks out for Chopper, and Chopper looks up to him.
Zoro wanted to see if he was worthy of Mihawks little knife necklace thing so he threw it it the air (like his cursed sword) and it slashed his eye which meant he still wasn't worthy to wield that knife.
Mihawk's strength is so great that Don Krieg accuses him of having the power of a Devil Fruit. While it has not yet been officially confirmed that he does not, it has only been indicated that his abilities are from pure skill and power.
It is evident that the only person capable of surpassing Roger is Luffy. Even though Luffy still has a lot to achieve, he is the only person who can transform the entire world.
In the 98th volume of One Piece, Oda answered a fan question about what Devil Fruits would fit Nami, Zoro, Sanji, Usopp, and Franky best. Nami's Fruit is the Rumble Rumble Fruit, which lets its user wield the power of lightning.
In a Water 7 filler episode, Sanji finds another hint of the All Blue's existence. Salt is brought by the Aqua Laguna from all the seas and Sanji compares it to the All Blue. It is shown to be such a good seasoning that a small amount in food is enough to outclass even his own cooking.
Over the years, he has come a long way and become one of the strongest pirates on the seas. Zoro has attained terrific strength, but he does not rely on a Devil Fruit at all.
