Zoro is a renowned powerful swordsman, who was revered in the East Blue even at the time when he hadn’t yet joined the Straw Hats. Known around the globe as “Pirate Hunter Zoro”, he is a fine swordsman, who developed his own Three Sword Style technique while training in Shimotsuki Village in the East Blue. Even without possessing any Devil Fruit abilities, Zoro is considered to be a dangerous opponent, and most enemies would rather escape than facing off against him.
His skills developed over time, but when Zoro faced Mihawk, the greatest swordsman in the world, he vowed to become the strongest after getting overpowered by Mihawk’s formidable skills and sword. Zoro vowed to defeat and slay Mihawk someday once he gets stronger, and even so, during the time-skip, he trained under Mihawk’s guidance.
Zoro also has an extreme level of durability and strength to stand still even after suffering a massive amount of shock and gruesome attacks. Zoro has repeatedly fallen from rooftops and other tall entities, but none of these falls have seriously harmed him. During the Thriller Bark arc, after experiencing Luffy's pain, Zoro bled abundantly until his body was covered in blood, as were many of the rocks in the area. Zoro, on the other hand, not only survived this but also managed to stay awake until his crewmates recovered. At that point, he told them that nothing had happened.
Strength
Zoro is mighty physically and regularly spends his time at sea lifting massive objects to keep getting stronger. Zoro's strength greatly influences his swordsmanship since his blows have tremendous force and range in their cutting ability.
Thanks to his strength, Zoro can easily knock superhumanly massive and powerful opponents into the air. He can also quickly dispatch smaller opponents. Zoro is so strong that he has frequently picked up, carried, and tossed opponents of similar stature with relative ease.
Zoro used a skill called No Sword Style, which lets him use the physical might of his body to produce shockwaves that resembled his sword slashes when he was without swords during the event in the Davy Back Battle. With his forward-thrusting arms, he unleashed a whirlwind force, sending the opponent spiraling into his comrade.
Speed and Agility
Zoro has shown incredible speed and agility when pursuing enemies and dodging their strikes. He can quickly chop down opponents and draw and redraw the sword before they have time to react. He also possesses unusual quick reflexes, and jumping and climbing strength.
After the time jump, Zoro has proven he can swim underwater with great speed and can go across the ocean's depths.
Durability and Endurance
Zoro has incredible levels of toughness and stamina, as he has fought and moved about after suffering several severe wounds. His unexplainable pain tolerance is one of his greatest strengths as a warrior.
Swordsmanship
Zoro is a brilliant and skillful swordsman; through his training in the Isshin Dojo in Shimotsuki Village since he was a little child, he consistently beat adult swordsmen in the duel, with Kuina being the only exception. He became a superb master swordsman after reaching adulthood and became famed for using three swords in combat.
Zoro is famed for wielding three swords, which has led to the term "Three Sword Style," yet he is also skilled enough to use two or even one, with the former being his original technique. His swordsmanship combines great strength to overwhelm opponents and inflict substantial harm on them; nevertheless, this is made possible by the quality of the swords, as weaker ones would break. Zoro is strong enough to throw flying slashes that can cut and harm objects outside his normal vision field.
Zoro has frequently used animal-like spirits, which frequently appear around him when he prepares an attack, particularly when using No Sword Style. However, this aura shows no signs of being linked to Haki before or after the time skip, the potential manifestation of Zoro's killing spirit or intent.
After the time skip, Zoro has demonstrated that he can still carry out his attacks despite losing one of his swords by using other types of blades.
Three Sword Style
Zoro created the "Three Sword Style," which inspired him to excel as a master swordsman. This is his favorite combat style against multiple strong opponents, even though it involves unconventionally using three swords, holding one in each hand and one in the mouth.
Zoro frequently uses all three swords in his Three Sword Style techniques, repeatedly slicing one or several opponents simultaneously. He can produce whirlwind-like attacks with his Three Sword Style soaring slashes that have the potential to grab and strike a large number of enemies at once. He can effectively evade attacks with all three swords and even block attacks from numerous opponents at once.
King of Hell Three Sword Style
In the King of Hell Three Sword Style, Zoro goes all out with Busoshoku Haki and Haoshoku Haki, greatly enhancing the power and range of his attacks over either of his earlier styles. The King of Hell Three Style Sword is based on Zoro letting Enma use up all of his Haki, and he can't sustain this for too long before running out of Haki and would need time to replenish it.
Two Sword Style
Before learning the Three Sword Style, Zoro's preceding fighting style throughout his formative years was the Two Sword Style. Similar to the Three Sword Style, Zoro is a master of this form of swordplay, dual-wielding two of his swords with considerable strength and ability while combining soaring slashes and drawing and redrawing his moves.
One Sword Style
Zoro is a master of the One Sword Style. He has used it frequently to execute finishing moves against various enemies. Flying slashes and other unsheathing and re-sheathing methods are used in this style, much like the Two Sword Style, mostly to defeat or harm formidable opponents with a single attack.
Nine Sword Style
The Nine Sword Style is the most severe use of Zoro's spirit projection skills. When he becomes sufficiently enraged, a dark aura forms about him. He manages to build an illusion of himself with numerous heads and arms capable of slicing through the most formidable opponents and giving him the power of nine swords. Zoro's strike power triples despite the fact that it seems to have a completely spiritual character.
Foxfire Style
Zoro was initially drawn to the Foxfire Style, the distinctive sword technique used by Kin'emon, the leader of the Nine Red Scabbards. Zoro is known to have "stolen" this method. He can extinguish flames.
Current Swords
Zoro is known to have owned seven swords—all katanas—and occasionally borrowed numerous additional swords and weapons. He typically keeps three swords on hand simultaneously because of his Three Sword Style.
Wado Ichimonji
Wado Ichimonji is one of the 21 Meito of the Great Grade. It was forged by Shimotsuki Kozaburo, a renowned Wano swordsmith, and primarily owned by his granddaughter Kuina, a close friend of Zoro.
Sandai Kitetsu
Sandai Kitetsu is A Grade Meito, considered "cursed, " which would cause its owner severe harm. It was handed to Zoro by the weapons dealer Ipponmatsu in Loguetown, before the time skip. It was forged by the legendary Wano swordsmith Kozuki Sukiyaki.
Enma
Enma is one of the 21 Meito of Excellent Grade Swords. The famed warrior Kozuki Oden was the first to use this sword. It was also crafted by Shimotsuki Kozaburo. Kozuki Hiyori, the daughter of Oden, inherited Enma, and gave it to Zoro in exchange for his vow to take Shusui back to Ryuma's grave. Enma has the unique ability to draw a significant amount of Busoshoku Haki from the user.
Previous Swords
Shusui
One of the 21 Great Grade Meito, Shusui is a potent Black Blade. The great samurai Ryuma is credited with using it, and Wano Country holds it in high regard.
Yubashiri
Yubashiri is one of the 50 Meito of the Skillful Grade. After seeing the swordsman's enormous fortune, Ipponmatsu presented it to Zoro, which had once been a family heirloom for Ipponmatsu.
Unnamed Blades
Zoro had two nameless katanas that Shimotsuki Kozaburo gave him as a kid. They were used with Wado Ichimonji for an unknown amount before being broken during Zoro's first fight with Dracule Mihawk.
Other weapons
Zoro used some weapons as a substitute when he had a sword missing or broken. He used these weapons to use his Three Sword Style. Here’s a list of those weapons.
Zoro used Johnny and Yosaku's Nakiri swords, which he had borrowed, to battle in Arlong Park while wielding just Wado Ichimonji.
Yubashiri was once replaced with a Marine cutlass for the battle on Enies Lobby, and it was ultimately destroyed.
Zoro used a tanto intended for him to execute seppuku to kill Toyama Tsujigiro.
Kamazo was using a scythe, which Zoro took after it stabbed him and used to kill Kamazo in place of the missing Shusui.
Haki
Being an already master swordsman, Zoro’s Haki is a formidable power during his battles. He is known to be one of the few people who wield all three forms of Haki.
Haoshoku Haki
Zoro can use Haoshoku Haki, a highly distinctive kind of Haki whose users are said to possess kingly traits. Zoro was unaware he possessed this power, which had lain latent within him. His three swords will all originate black lightning due to the advanced application he may use to infuse it into them.
Busoshoku Haki
Zoro has a high level of proficiency with Busoshoku Haki. After learning it from Dracule Mihawk, it became his primary expertise. He mastered hardening and imbuement during the two-year time gap, making both black. Despite this, hardening and Busoshoku Haki are frequently used in intense combat to injure Logia users.
Kenbunshoku Haki
Zoro is a very adept user of Kenbunshoku Haki as well.
