Although Gol D. Roger is a legendary figure, the emergence of ancient beings and new power variations has reshaped the Haki hierarchy in the world of One Piece.
1. Rocks D. Xebec (Domi Reversi Form)
While the regular Rocks was on par with Roger and Garp, in his Domi Reversi state he becomes a true nightmare. Combining incredible regeneration with a full-body Conqueror’s Haki armor, Rocks forced Roger and Garp to join forces and pour all their Haki mastery into a single strike just to break through his defense. In this form, Roger alone stood no chance.
2. Harald (Holy Knight Form)
Harald has long been a rival capable of going toe-to-toe with Rocks. After joining the Holy Knights and receiving a boost from Imu, this ancient giant’s power soared even higher.
Even Scopper Gaban and Shanks struggled to hold him back. Unlike Rocks, who retained some humanity, Harald under Imu’s control became a ruthless killing machine, only briefly regaining clarity after Loki’s awakening strike.
3. Imu – The Supreme Being
Imu’s strength lies not only in authority but in a unique and unparalleled quality of Haki. Legendary Scopper Gaban, who survived the God Valley battle and faced many Haki monsters, admitted he had never felt a pressure as strange and terrifying as Imu’s. This Haki transcends all known pirate standards.
4. Joy Boy – The Ultimate Power
If Imu’s Haki is unique, Joy Boy’s is overwhelming. With a single stored burst of Conqueror’s Haki, Joy Boy instantly dispersed the beast forms of the Five Elders, sending three of the four Gorosei fleeing straight back to Mary Geoise.
Even Imu, the world’s supreme ruler, trembled and knelt upon sensing Joy Boy’s Haki after centuries. There is no doubt that Joy Boy holds the strongest Haki in history.
