One Piece: The Least Powerful Conqueror’s Haki Users

Essential Insights

Characters with Conqueror’s Haki vary in strength and ambition; for instance, Don Chinjao demonstrates this ability but is often viewed as a lesser user.
Strong willpower is commonly found among Conqueror’s Haki wielders, including figures like Portgas D. Ace and Roronoa Zoro.
Even powerful characters such as Charlotte Katakuri are influenced by their loyalties to those they serve.

Conqueror’s Haki, also referred to as Supreme King Haki, ranks among the most formidable powers in One Piece. Unlike other forms of Haki that can be cultivated through training, this ability is a distinguished trait possessed only by a select few potent individuals. Those who harness this power can force their will upon others, proving advantageous in various combat scenarios.

The precise origins of Conqueror’s Haki remain ambiguous, yet it appears consistently manifested in individuals who are innately ambitious and possess great strength. Although not officially confirmed, a hereditary link may exist, as certain users have been noted to inherit this power from their parents or grandparents. This article aims to explore the contentious topic of the least formidable users of Conqueror’s Haki. Given the natural filtering that occurs among weaker characters, even those identified as “weakest”truly retain significant strength within the broader narrative. Some may even surprise fans by proving their worth as the story unfolds.

1 Don Chinjao

Former Leader Of The Happo Navy

Debut: Chapter 407 (Manga); Episode 632 (Anime)

Don Chinjao, previously a pirate chief and head of the Happo Navy, was famously recognized for his unique drill-like hairstyle. In his prime, he was capable of battling esteemed figures such as Monkey D. Garp. However, their repeated confrontations resulted in Garp altering Chinjao’s head shape, leading to a long-standing grudge against him and subsequently his descendants, including Monkey D. Luffy. In a Haki-fueled encounter with Luffy, Chinjao’s head was restored, allowing him to finally release his grudges toward the Monkey family.

Chinjao later faced off against his grandson, Sai, when Sai intervened to save Baby 5 from taking her own life. Ultimately, Sai managed to bend Chinjao’s drill-head and take control of the navy, signifying the passing of the torch. While Chinjao retains a level of strength, his comparison to Sai showcases that he is most likely the weakest known user of Conqueror’s Haki.

2 Portgas D. Ace

Second Division Commander Of The Whitebeard Pirates

Debut: Chapter 154 (Manga); Episode 91 (Anime)

The renowned Ace possessed extraordinary willpower from a young age, demonstrating his Conqueror’s Haki capabilities by incapacitating foes before he even comprehended its significance. Being the son of Gol D. Roger, he led his crew, the Spade Pirates, but ultimately joined Whitebeard’s crew after facing challenges in the New World.

By the time events of One Piece unfold, Ace had fully embraced his role as a Division Commander, with his authority lying under the influence of Whitebeard, who also wielded Conqueror’s Haki. Although Ace has possessed this power conceptually, his childhood display of Haki marked the only time it was showcased in the main narrative.

3. Roronoa Zoro

Swordsman Of The Straw Hat Pirates

Debut: Chapter 3 (Manga); Episode 1 (Anime)

Zoro stands out as one of the most determined pirates serving under a captain. Recently, he discovered his own mastery of Conqueror’s Haki, which he now utilizes to enhance his fighting prowess. This growth aligns with his ambition to become the saga’s strongest swordsman, complementing his captain Monkey D. Luffy’s goal of becoming King of the Pirates.

Though Zoro ranks among the crew’s top fighters, he typically confronts formidable opponents, especially those skilled in swordsmanship, opting not to target the primary antagonist unless absolutely necessary. Zoro exhibits an unwavering resolve and a refusal to accept defeat, but he also respects his captain’s lead, asserting his prerequisites for Luffy’s competency as captain. However, throughout their journey, he has never acted on his threats and has remained loyal to Luffy since they joined forces.

4. Charlotte Katakuri

Minister Of Flour/Sweet Commander Of The Big Mom Pirates

Debut: Chapter 860 (Manga); Episode 825 (Anime)

Charlotte Katakuri, son of Charlotte Linlin, stands as the second mightiest member of the Big Mom Pirates, following only his mother. In a crew filled with siblings of varying prowess, Katakuri distinguishes himself as one of the most formidable fighters, consistently advancing to the frontline. His exceptional skill warranted him the title of Sweet Commander, an honor shared with his siblings Smoothie and Cracker.

While Katakuri demonstrates considerable willpower, his ambitions appear clouded by his unwavering loyalty to his mother. He seems satisfied with obeying her commands, showcasing her dominating influence over him. Katakuri faced a legitimate defeat at the hands of Luffy, who exhibited significant improvement in his Haki during their battle. Depending on the future developments concerning his mother’s potential demise, this might shift Katakuri’s dynamics in seeking his ambitions; however, for the time being, he has faced defeats in both physical confrontations and the hierarchy of his crew.

5 Eustace Kid

Captain Of The Kid Pirates

Debut: Chapter 498 (Manga); Episode 392 (Anime)

Eustass Kid shares a parallel ambition with his rival Monkey D. Luffy: aspiring to become the King of the Pirates. However, their strategies diverge significantly, with Kid exhibiting a penchant for destruction without considering the consequences. After joining forces with Trafalgar D. Water Law to defeat Big Mom, he aimed to confront another Emperor of the Sea.

Yet, Kid’s overestimation of his abilities, coupled with his reckless behavior, ultimately led to his downfall. Shanks anticipated the devastation Kid could wreak and managed to defeat him, while Dorry and Broggy annihilated his ship. This outcome partially stemmed from Shanks utilizing his superior Conqueror’s Haki. Post-battle, it remains uncertain whether Kid’s crew survived, but the confrontation confirmed that Kid’s resolve was inferior to that of Shanks.
