Quick answer: does Zoro finally use Conqueror's Haki on Sommers?
Once — and it doesn't land on Sommers. In ONE PIECE chapter 1194, Zoro lands one strike that Sommers himself identifies as coated in Conqueror's Haki. That strike cuts through Sommers' thorn creatures and smashes into a ship. Zoro then tries again and again, and it will not come back.
The chapter is not about Zoro mastering Conqueror's Haki. It is about him getting it once and not being able to repeat it. It ends with Zoro in a three-sword stance, black lightning-like effects drawn around it, and Sommers terrified — and no strike is shown.
PRIMARY — MANGA VERIFIED. Read directly from the official Japanese release: chapter 1194「万物は変わりゆく」in Weekly Shonen Jump 2026 issue 44, published September 28 on Shonen Jump+. Spoilers below. English wording is our paraphrase of the Japanese, not a quotation from the official English translation.
Sommers' read on the chapter 1193 strike
Chapter 1193 ended with Zoro's blade through Sommers' torso and Sommers still alive. Our 1193 report left one question open on purpose: did the attack miss the heart, or did it reach the heart without Conqueror's Haki?
Chapter 1194 opens with Sommers' own answer. As his wound closes, he says the strike had his heart fully targeted, but was not coated in Conqueror's Haki. Because Zoro had used it earlier in the fight, Sommers reasons that Zoro cannot handle it at will — that his strength is uneven, there one moment and gone the next.
That is Sommers' reading, not a narrator's verdict. It matters because the rest of the chapter behaves as if he is right, but it is still one character's judgement of another.
From there Sommers treats every exchange as a test. After Zoro's next hit he asks himself whether it carried Conqueror's Haki, and decides it did not. He mocks Zoro for practising on a God's Knight, and later tells him to give up because he has no qualities of a king.
The one strike that worked
Zoro keeps attacking, and keeps judging his own hits as wrong. Midway through, he thinks it through out loud. How do you coat a blade with it? It is the thing Luffy uses to drop a whole crowd at once. He had thought it only lodged in someone who captains a crew. When Sommers asks whether he can support a Yonko's captain like this, Zoro concedes it is a fair point.
Then comes 千八十煩悩鳳 — a new version of his long-range 煩悩鳳 (Pound Hō) slash — and Sommers reacts immediately: it's coated — Conqueror's Haki.
The coated strike does not hit Sommers. It tears through his thorn creatures and slams into a ship moored nearby. Someone aboard shouts about the ship. Sommers panics for a different reason: if it breaks any further, he says, he won't be able to carry the children.
So the chapter's one confirmed Conqueror's Haki strike from Zoro — confirmed by his opponent — damages a ship, not Sommers' heart.
The turn: "It won't come back"
The rest of the fight is the point of the chapter. Zoro cuts Sommers again and again, and each time rejects the result: not it, not it, not it. He takes off Sommers' hand. Sommers says that will heal as well.
Then Zoro — identifiable by the scar over his closed left eye — says 「戻らねェ!!」: it won't come back, followed by a baffled but I'm not doing anything…!? Whatever made that earlier strike carry Conqueror's Haki, he cannot find it again on demand.
Sommers laughs that Zoro will never be able to use it.
That is the development chapter 1194 actually confirms: Zoro has Conqueror's Haki and has now coated a blade with it in this fight, but he cannot yet reproduce it at will. It is the same distinction our Haki rankings draw between possessing Conqueror's Haki, infusing it once, and controlling it. Why he cannot call it back is a separate question, and the chapter only gives three kinds of evidence on it — we lay them out here.
Mihawk's lesson: "oneself"
Threaded through the fight is a flashback to Zoro's training with Mihawk, and it supplies the chapter's title.
Mihawk tells him that all things change, but one thing can stay unchanged, and asks him why. He says the other kind of Haki is not something you gain by training; it is the one unchanging thing that kings always carry. And, on the last page: remember — Conqueror's Haki is "oneself" (己), strong enough that the weak cannot stand.
That is Mihawk's definition, in dialogue. Chapter 1194 does not turn it into a rule or show how it applies to Zoro's problem beyond placing it on the last page, around Zoro's final stance. Read it as the lesson the chapter frames the fight with, not as a mechanic. We go through the four lines, and how they sit beside Rayleigh's and Gaban's statements, in our piece on Mihawk's definition.
