The world of One Piece is full of legends, but every now and then, Oda pulls back the curtain to reveal someone even more monstrous than we ever imagined. The Elbaf arc has already delivered intense battles, some crazy lore, and yes, more power-ups, but chapter 1139 introduced a twist that left fans speechless. Just when it seemed like we had seen the strongest Observation Haki users in action, Oda revealed that one man stands above them all. And trust me, it’s not who you expected.
This article contains spoilers.
Scopper Gaban Reigns Supreme in Observation Haki
The Elbaf arc in One Piece is proving to be one of the most thrilling arcs in the series so far. But just when it seemed like things couldn’t get any crazier, One Piece chapter 1139 dropped a bombshell: the strongest Observation Haki user in Elbaf has been revealed.

And it’s not Luffy. Or even a Yonko.
Instead, the honor goes to a living legend: Scopper Gaban, the former left-hand man of Gol D. Roger.
The Amazing Observation Haki Users of Elbaf
Elbaf is home to some of the strongest Observation Haki users we’ve seen so far. This shouldn’t come as a surprise, given that Luffy himself—now a full-fledged Yonko—is in the mix.

Luffy trained his Observation Haki to an elite level during the Whole Cake Island arc, unlocking Future Sight. His ability to predict attacks and read his opponent’s moves made him a force to be reckoned with. Over time, he has refined this skill, showcasing even greater control in his fight against Kaido.
Sanji, another formidable Observation Haki user, is known for his heightened sensory abilities. His reflexes and awareness often surpass even Luffy’s in base form, making him an exceptional user of the Color of Observation. While he hasn’t unlocked Future Sight, his instincts are razor-sharp, allowing him to react to threats almost instantly.

Despite these impressive feats, neither Luffy nor Sanji comes close to Scopper Gaban’s sheer mastery of Observation Haki.
Scopper Gaban Has The Best Observation Haki On Elbaf
Chapter 1139 officially introduced Scopper Gaban into the present timeline, and it was clear from the start that he was no ordinary pirate. As one of Roger’s closest crewmates, Gaban was known for being on par with Silvers Rayleigh, making him a truly legendary figure.
But what set him apart in this chapter was his mind-blowing sensory perception.

While at Aurust Castle, Gaban revealed that he sensed a “sinister Haki” emanating from within the castle—something neither Luffy, Zoro, Sanji, nor even the mighty Giant warriors partying nearby could pick up on. And by the time he arrived, the presence had vanished entirely, further proving just how refined his Observation Haki truly is.
Gaban’s Haki Spans An Entire Island
What makes this revelation even crazier is that Gaban’s Haki doesn’t just cover a room or a battlefield—it spans across the entire island of Elbaf. The fact that he could detect a disturbance from such an insane distance places him in a league of his own. This isn’t just advanced Observation Haki—this is next-level mastery.
How Strong Is Gaban’s Haki?
To understand just how terrifying Scopper Gaban’s Haki is, it’s important to remember his standing in the One Piece world. He was a direct rival to Silvers Rayleigh, who himself could hold his own against the likes of Kizaru even in old age.

According to Oimo and Kashi, the two Giant warriors, Gaban has been living on Elbaf for over 20 years, honing his skills in isolation. If he was already a monster during Roger’s time, imagine how much stronger he has become with two decades of additional experience.
Does Gaban Have Conqueror’s Haki?
While this chapter focused on Gaban’s Observation Haki, it’s highly likely that he possesses all three forms of Haki, including Conqueror’s Haki. After all, to be considered an equal to Roger and Rayleigh without a Devil Fruit, one would need to rely on raw power and advanced Haki techniques.

With Luffy, Zoro, and Nami now set to face off against Gaban in the next chapter, fans are eagerly waiting to see just how overwhelming his abilities truly are. As Oda continues to shake up the power dynamics of One Piece, the introduction of Scopper Gaban as the strongest Observation Haki user in Elbaf is just another reminder that the Final Saga is going to be absolutely insane.
With the battle against Gaban looming, it remains unclear whether Luffy and his crew can match up to this living legend. But one thing is for sure: One Piece fans are in for an unforgettable ride.
