One Piece: The Strongest Haki-Only Fighters In The Series, Ranked

This piece focuses solely on figures who possess an exceptional mastery of Haki, hence some well-known and widely appreciated characters might not feature in it.

As a dedicated fan, I can’t hide my excitement when discussing the captivating world of One Piece! While Devil Fruits undeniably serve as the narrative’s primary power source and have catapulted legendary characters to unprecedented heights, it’s essential to acknowledge that they are not the ultimate power in this intriguing universe. That prestigious title is reserved for Haki, a fascinating manifestation of one’s willpower projecting outside their body. However, delving deeper into its complexities reveals a myriad of types, each with their unique subtleties that add layers of depth to the storyline.

In Luffy’s fight against Kaido, the Beast King asserted that Haki is crucial for dominating the Grand Line, and it’s evident with several formidable characters within the One Piece universe who possess immense strength primarily due to their mastery of Haki. This article will examine the strongest of these characters to understand why they remain so highly revered.

Zoro Has Reached Over A Billion Berries Through Haki And Sword Skills

Epithet: Pirate Hunter, King of Hell

• Zoro plans to become the world’s strongest swordsman.

In simpler terms, many fans think that Sanji and Zoro are equally important within the Straw Hat crew. However, as of now, Zoro is generally considered more powerful than Sanji, given his relentless pursuit of strength and mastery over swordsmanship. Post-time skip, Zoro was recognized as the top user of Armament Haki among his team members. Since then, he has continued to grow stronger and even acquired Conqueror’s Hiki, further expanding his formidable skillset. While there is still a lot to learn in mastering Conqueror’s Haki, Zoro’s current abilities place him at an advantage over Sanji.

Kozuki Oden Almost Killed Kaido In A Single Hit, Showing His Power

Epithet: Idiot Lord

• Oden was a masterful user of one of the world’s deadliest swords.

In simpler terms, there aren’t many characters in the series whose stories are as heart-wrenching as that of Kozuki Oden. However, his legacy lives on due to his immense strength in the past, especially for his single blow that nearly defeated Kaido. Unfortunately, he was diverted at a crucial moment which prevented him from finishing off Kaido.

Oden is unique among characters in One Piece, being one of the few who could utilize Conqueror’s Haki, and it’s suggested that he even mastered its advanced forms. Furthermore, Oden was the only character before Zoro who could fully control Enma, a feat made challenging due to the sword consuming a user’s Haki on its own.

Silvers Rayleigh And Scopper Gaban Were The Wings Of The Pirate King

Epithets: Dark King, Mountain Eater

• The Wings of the Pirate King.

In the annals of their story, Rayleigh and Scopper stand out as two figures whose power echoes globally. Known for their immense strength and legendary status from the bygone era, these individuals are respected Haki users who were so equally matched that it remains debatable, even now, which one was superior. This tension was evident during the Elbaf arc when Scopper corrected someone stating Rayleigh as the second strongest. Both have exhibited Advanced Conqueror’s Haki, placing them in a distinct tier within their realm.

King Harald Was Able To Clash Equally With Rocks When They First Met

Epithet: Greatest King of Elbaf

• The greatest monarch of Elbaf.

Even though Harald was globally recognized for his efforts towards peace and transitioning Elbaf beyond its warlike reputation, it’s worth noting that he was one of history’s strongest fighters. This fact became evident when he squared off against Rocks during the culmination of Reverie years ago. Their confrontation, though brief, demonstrated their immense power as they both employed Conqueror’s Haki, leading to a shockwave measuring approximately 5 kilometers and emitting black bolts of Conqueror’s Haki across the area. This showdown underscores Harald’s equal standing among top-tier fighters like Rocks.

Mihawk Became The World’s Strongest Swordsman Because Of His Haki

Epithet: Hawk Eyes

• Mihawk was Shanks’ rival.

Shanks, one of the powerful Yonko in current times, stands out as perhaps the strongest among them. Yet, to be considered Mihawk’s equal speaks volumes about his power. The title of ‘World’s Strongest Swordsman’ requires extraordinary might, and raw sword skills alone can only get you so far. This is where Mihawk’s proficiency in Haki comes into play, particularly evident in his ability to transform Yoru into a Black Blade – a feat achievable only when a weapon is infused with a significant amount of Haki over time. Mihawk’s strength is not just renowned; it serves as an ultimate test for Zoro.

Shanks Has Displayed The Greatest Haki Feat Of The Modern Era

Epithet: Red Hair

• Shanks is a master of Haki.

Among the contemporary pirates, it could be convincingly argued that Shanks boasts an exceptional command over Haki. His Conqueror’s Haki is among the most powerful ever witnessed, and he appears to have attained proficiency in the advanced forms of Observation and Armament Haki too. Remarkably, at the tender age of 15, he managed to learn Roger’s renowned ‘Divine Departure’ technique merely by observing it. Furthermore, his Conqueror’s Haki once subdued a Navy Admiral from a distance, demonstrating his exceptional mastery over this ability in One Piece, making him the most potent and skilled Haki user of modern times.

Monkey D. Garp Was The Rival Of The Pirate King And The Strongest Marine

Epithet: Hero of the Marines

• Garp’s Haki is said to be some of the strongest ever.

In the Navy, there’s a standout figure, often referred to as the Pirate King, and that honor belongs to Garp. Garp and Roger were formidable adversaries, known for their balanced strength. Their exploits have cemented them as two of the most powerful figures in history. It is said that Garp, along with another character, was instrumental in vanquishing Rocks D. Xebec during the God Valley Incident. Remarkably, even in his later years, Garp managed to single-handedly face off against the entire Blackbeard Pirates crew.

Gol D. Roger Was The King Of The Pirates Due To His Legendary Strength

Epithet: King of the Pirates

• The greatest pirate of them all.

Throughout the tale, no character holds more significance or impacts the story more profoundly than Gol D. Roger; the sole individual to discover the One Piece treasure and earn the title of Pirate King. Undoubtedly, this prestigious title was unattainable without Roger’s considerable might, as he was renowned for commanding the world’s seas without a Devil Fruit, instead relying solely on his mastery of Haki. His strength was such that he could effortlessly obliterate Oden with a solitary attack and stood shoulder-to-shoulder in combat with Garp, even though they were sworn rivals who reluctantly allied to vanquish Rocks.

Rocks D. Xebec Was the Strongest Pirate The World Had Ever Seen Since Joyboy

Epithet: Unknown

• The quintessential pirate.

In terms of historical significance, Rocks D. Xebec, often overlooked, was undeniably the dominant force in the past, surpassing heavyweights such as Roger, Garp, and Whitebeard. Though it’s commonly debated whether he consumed a Devil Fruit or not, even prior to that, Rocks was one of the most formidable characters globally. His exploits included breaking into Marijoa as a novice pirate and slaying a Navy Admiral, a feat few could match. Later, it took the joint effort of Roger and Garp to defeat him, solidifying his reputation as the strongest pirate of his generation, with Haki-infused swordplay that felt like gunfire.
