The Buccaneer race in One Piece represents one of the most enigmatic elements of the storyline, primarily due to its limited exploration in the narrative. Among the various mysteries surrounding this race, the most profound pertains to the transgression that led to their enslavement. Intriguingly, this crime may be intricately tied to the series’ power scaling, particularly the development of Haki.
Understanding the Buccaneers: Willpower and Haki
Notably recognized for their formidable willpower, the Buccaneers may have been the first to awaken the potential of Haki, the vital force representing a person’s spiritual energy. Furthermore, it’s suggested that members of this race might possess the ability to share their Haki with others. This capacity could be viewed as the ‘sin’ against the World Government, prompting an attempt to diminish their remarkable willpower by subjecting them to slavery.

The Buccaneers are part of a nearly extinct race characterized by their giant-like physicality and immense strength. They were prominently featured during Kuma’s flashback in the Egghead Arc, highlighting their unyielding willpower. Among the notable figures of this clan is Bartholomew Kuma, the last known survivor and father of Jewelry Bonney.

During Kuma’s recollections, it becomes clear that the Buccaneers committed a grave sin against the World Government, culminating in their enslavement. Paradoxically, it is suggested that this sin may stem from their incredible willpower, potentially serving as the foundation of Haki itself. Given that the World Government already faces challenges from Devil Fruits, the emergence of Haki may have posed an even greater threat.
It’s theorized that the Buccaneers could indeed have invented Haki, sharing their remarkable gift with the rest of the world. The suppression of their willpower likely was a strategic move by the Monarch, aiming to eliminate the potential dangers posed by this race. This suppression might have contributed significantly to their eventual decline, as the relentless pursuit to extinguish their spirit led to acts of violence against them.
Implications for Future Storylines
Examining the correlation between ‘willpower’ and ‘Haki’ provides an intriguing perspective, especially since only a select few characters in One Piece demonstrate mastery of this ability. This connection could enrich the lore surrounding Haki, establishing it as the second pillar of power scaling after the formidable Devil Fruits, and highlighting its significance within the broader narrative of One Piece.
