When Does Luffy Use Conqueror'S Haki

Luffy uses Conqueror's Haki in the 'One Piece' anime during Episode 783. It's such a powerful moment when he stands up against the New Fish-Man Pirates. That scene really showcases his growth and determination!

Avid 'One Piece' junkie here! So, Luffy first unveils his Haki in the Marineford arc. Specifically, it happens in Chapter 570 when he knocks out a pack of wolves without touching them. However, it's only after his training with Rayleigh that he really gets a handle on it, which is post-timeskip.

I've gone back and forth on this. The first moment we see him use it is at Marineford, but that doesn't mean he couldn't have had it dormant before. Roger's crew was full of monsters, and Ace had insane potential. He had the will and the bloodline for it, obviously. But I lean toward no, he awakened it later. His whole arc is about stepping out of Roger's shadow and becoming his own man; unlocking Conqueror's feels like a part of that growth, a declaration of his own worth. If he'd had it as a kid on the Moby Dick, I feel like we would've gotten a hint, or Whitebeard would have commented on it. The way it erupts when he's utterly enraged protecting Luffy feels like a first awakening to me. That said, Oda loves his parallelisms. Luffy awakened his facing down the Boa sisters. Maybe Ace's first true spark was in a similarly desperate, protective moment. We just never got the flashback panel of a young Ace making a crowd faint on some random island.

Man, I've rewatched Marineford so many times trying to catch every detail, and Ace's Conqueror's Haki usage is actually pretty subtle. It's not like Luffy's big explosive bursts. The clearest moment is when he's trying to escape the execution platform with Luffy. All those Marines are closing in, and you see a wave of it knock a bunch of them out cold. It's a defensive, get-the-hell-off-me kind of blast. It makes sense for his character in that moment—he's backed into a corner, protecting his brother, and it just erupts. Thinking about it, he probably used it earlier in life too, maybe unconsciously. A kid with that much innate willpower? No wonder he drew so many strong people to him. It fits that his Haki manifests in bursts tied to extreme emotion, not as a refined tool. We never got to see him master it like the older legends, which honestly adds to the tragedy. He had the king's spirit but never the time to fully wield it.

I've always found the glimpses of Ace's haki to be these subtle, powerful character moments rather than huge set pieces. The clearest display is when he saves Luffy from Bluejam's pirates on the Gray Terminal, years before the main story. He just stands there, radiating that pressure, and knocks a bunch of guys out cold. It's raw and untrained, but it's absolutely Conqueror's—it's that same 'intimidation' Shanks used on the Lord of the Coast. It's interesting because it frames his potential; he had the kingly qualities from a very young age, even if he never fully mastered that specific power on-screen like Luffy did later. Honestly, that's pretty much it for explicit, undeniable scenes. A lot of the 'could it be?' discussions revolve around his general aura and reputation. When he faces Whitebeard for the first time and that massive shockwave clash happens, some fans theorize Conqueror's was involved, but it's never confirmed. I lean toward it just being a crazy powerful physical clash mixed with his Flame-Flame Fruit. The story shows us his strength in other ways, making that early haki flashback feel even more special—a promise of what could have been.

The exciting adventures of "One Piece" describe only a few who have it as special energy called Conquerer's Haki. Just to name a few: Monkey Del Blue, leader of pirate crew Straw Hat Luffy and a man who roams from ocean to ocean seeking freedom; Gol D.Roger the Pirate King; SilversRayleigh, right-hand man to the Pirate King; and Whitebeard, the strongest man in the world I thought of these people. But they're not just strong! They all have that certain something being able to dominate or frighten others purely by force of personality alone.

Looking at Ace's fights in the main story, I don't think we ever see him consciously use Conqueror's Haki in a direct offensive way like Luffy or Kaido do. He definitely has it—the vivre card info confirmed he's a conqueror. But his battles in the manga and anime, against Blackbeard and Akainu, rely overwhelmingly on his Devil Fruit power and physical brawling. That said, the potential is fascinating to consider. He had the willpower and charisma to lead the Spade Pirates and become a Whitebeard commander. If he'd lived longer, maybe he'd have learned to coat his attacks with it, turning his 'Hiken' fist into something even more devastating. His battle style was always so aggressive and fiery, it feels like a missed opportunity we never saw those two aspects of his power combine on panel. Ultimately, his story was cut short, so 'effective use' in battle remains a big 'what if.' It fits his character, though—his strength was more about the raw, burning passion he inspired in others than a refined, domineering force.

Luffy first observed his Haki abilities unintentionally in front of Sandersonia during the Amazon Lily arc; however, he was not aware of it at the time. He didn't actually learn how to use and control the various forms of Haki until his training with Rayleigh during the two-year time skip. Rayleigh trains Luffy especially in Observation and Armament Haki, directing him to improve what he already possesses inherently. He also advised Luffy to work on his Conqueror's Haki from there, as this can't really be taught and is absolutely necessary for self-discovery followed by development into something. How the slow exposure of Haki and the slow way that Luffy learns it are integrated into the personality of a wacky character such as Luffy really lends depth to the story 'One Piece'.

To the best of my knowledge, Usopp from 'One Piece' hasn't shown any sign of possessing the Conqueror's Haki. This type of Haki is known to be extremely rare and is usually displayed by those with the qualities of a King! While Usopp's got tons of bravery and a never-give-up spirit, this particular Haki hasn't popped up in his arsenal. Though it'd definitely be a game-changer if he did have it. Just imagine the Sniper King knocking-out foes left, right, and center purely with his willpower!

To put it simply, it hasn't been explicitly confirmed if Monkey D. Garp, the legendary Marine vice admiral and Luffy's grandfather, possesses the Conqueror’s Haki. While it's known that Garp is incredibly powerful, holding his own against the Pirate King, Gold Roger, and even cornering him multiple times, the exact specifics of his abilities remain somewhat of a mystery. We know he has immense physical strength, and his proficiency with Armament Haki and Observation Haki is highly likely given his rank and combat capability. Yet, the question about whether he has the Conqueror’s Haki, a form of Haki that only a few individuals in the 'One Piece' world possess, still stands. With Garp's leadership qualities, charisma, and the respect he commands, it wouldn't be surprising if he does have Conqueror’s Haki. It's just a matter of waiting for an official reveal, if there is one awaiting us in the series. So, for now, fans can only speculate and wait for confirmation from the 'One Piece' creator, Eiichiro Oda. He always has a few tricks up his sleeve, and who knows, a revelation on Garp's abilities might be one of them.
