One Piece has once again shaken the fandom with a powerful reveal that might change the scale of the final war. The long-speculated puzzle of how to deal with the Holy Knights seems to have been cracked, and it's not merely brute strength; wielding Conqueror’s Haki to an entirely new level.As teased in the One Piece chapter 1152 spoilers, it appears only those proficient in the Conqueror’s Haki technique stand a chance. Although the spoilers are to be taken with a grain of salt, the huge reveal that Scopper Gaban has the ability to use the most uncommon Conqueror’s Haki had the fandom buzzing.Disclaimer: The article reflects the opinion of the writer, and it includes spoilers from the One Piece chapter 1152.One Piece chapter 1152 teases the Holy Knights' one major weaknessRecent One Piece spoilers have finally teased a concrete means of defeating the apparently unbeatable Holy Knights. Previously, in chapter 1152, a suspenseful instance when Scopper Gaban rescues Nico Robin from Saint Sommers provides an interesting instance. Gaban chops Sommers' arm right off with one deftly placed blow—though the real surprise isn't in the quickness of his attack, but in what follows.Sommers' arm is unable to regenerate, and for the first time, the immortality of a Holy Knight proves irrelevant. This is a turning point, and it is made clear in One Piece chapter 1152 that Gaban's Conqueror's Haki has advanced to a level potent enough to override regeneration altogether.Gaban's application of Conqueror's Haki not only defeats Sommers but reveals an underlying truth: Holy Knights are weak against Conqueror's Haki, but only when being applied at a capacity that most users cannot. His attack was not augmented by the power of a Devil Fruit, sword blessing, or external force.It was raw haki mastery, honed to the extent that it not only harmed the body but the soul as well. Most fans theorized that this sophisticated Haki works by cutting off a metaphysical or spiritual link that drives the Holy Knights' immortality. It is not about killing the flesh—it's about drowning the essence that makes it regenerate.The conflict also confirms long-standing theory that Gaban is a Haki user of the Conqueror type, now cemented as canon in this explosive chapter. His remark, "It's been a while," before defeating Sommers, suggests a past history between the two, one which would most likely go back to the God Valley incident.This is why Gaban was able to hit so accurately—his experience has already shown him what doesn't work, and this time he employed what does. With an assault using Conqueror's Haki honed to its elite level, he delivered a finishing blow no common technique could.Most fans assume this moment will be the standard for all future battles. Conqueror's Haki is no longer merely a marker of kingship or will; it is now the method used to shatter powers that were previously considered divine. The Holy Knights, previously untouchable in their ability to regenerate unnaturally, now possess an identifiable weakness.This also implies characters such as Luffy, Zoro, and possibly others will have to master their own Haki more if they are going to battle the remaining Holy Knights. With this revelation, the playing field is leveled. It's no longer brute strength or Devil Fruits. The war now depends on who can harness Haki at its sheer peak.Final thoughtsGaban as seen in manga (Image via Shueisha)The One Piece chapter 1152 spoilers reveal the much-anticipated secret to defeating the Holy Knights: advanced Conqueror's Haki. At a climactic moment, Scopper Gaban saves Nico Robin and perfectly cuts through Saint Sommers' arm, which does not regenerate. This shows that their immortality is not absolute if one possesses advanced Haki.Gaban's attack was neither powered by a Devil Fruit nor a special sword—it was a pure mastery of Haki that impacted their body and soul. Many fans suggest that this is a weakness of the Holy Knights' souls, which only those who possess advanced Conqueror's Haki can fully face off against them.Related links:Shanks is One Piece’s strongest Haki user (& it’s obvious why)Oda may have based Saint Killingham on this infamous Irish prison in One PieceHaki may work like frequency control in One Piece
