Which Episode Luffy Use Supreme Haki Instant

Monkey D. Luffy’s journey from a scrappy kid in the East Blue to a Yonko of the sea is defined by his mastery of Haki. While he uses Observation and Armament Haki frequently, nothing stops a show quite like Conqueror’s Haki (Haoshoku Haki), often referred to by fans as "Supreme Haki."

Because Luffy’s mastery of this rare power evolved over hundreds of episodes, there isn't just one answer. Depending on whether you are looking for the first accidental flicker or his ultimate mastery, here are the key episodes where Luffy uses Supreme Haki. 1. The Very First Hint: Episode 389

Long before the concept of Haki was explained to the audience, Luffy used it instinctively. During the Sabaody Archipelago arc, Luffy accidentally unleashed a burst of willpower to intimidate Motobaro, Duval’s large bison mount. The bull immediately collapsed, leaving the Straw Hats confused about what had just happened. 2. The Amazon Lily Outburst: Episode 413

The first major display of Luffy’s Supreme Haki occurred during his fight against the Gorgon Sisters, Boa Sandersonia and Boa Marigold. When the sisters attempted to smash a petrified Margaret, Luffy let out a primal scream of "Stop it!"

The resulting shockwave knocked out the majority of the execution spectators. This was a pivotal moment, as the Kuja Pirates—who are Haki experts—immediately identified it as "The Color of the Supreme King," noting that only one in several million people possess it. 3. Saving Ace at Marineford: Episode 478

Perhaps the most iconic early use of Supreme Haki happens during the Paramount War. As the executioners raise their blades to kill Portgas D. Ace, Luffy releases a massive, unintentional wave of Haki that ripples across the entire battlefield.

It knocked out the executioners and stunned everyone from the Navy Admirals to Whitebeard himself. This episode signaled to the world that Luffy was a global threat with the potential to stand at the top of the pirate world. 4. Post-Timeskip Mastery: Episode 518 & 554

After training with Silvers Rayleigh for two years, Luffy returns to Sabaody with full control over his Haki.

Episode 518: Luffy effortlessly knocks out the "Fake Straw Hats" and their crew without breaking his stride. which episode luffy use supreme haki

Episode 554: On Fish-Man Island, Luffy walks calmly toward Hordy Jones’ army of 100,000 subordinates. With a single glare, he instantly incapacitates 50,000 of them. This remains one of the most satisfying "flex" moments in the series. 5. The Clash of Kings: Episode 716 & 870

As Luffy enters the New World, he encounters other users of Supreme Haki.

Episode 716: Luffy clashes with Donquixote Doflamingo. When their kicks meet, black lightning crackles in the air—a visual indicator that two Supreme Haki users are colliding.

Episode 870: During the climax of the fight against Charlotte Katakuri, their Haki clash is so intense that it physically destroys the Mirror World surroundings and knocks out bystanders from a distance.

6. The Ultimate Evolution (Advanced Supreme Haki): Episode 1028

The most recent and significant milestone occurs during the Wano Country Arc. In his battle against Kaido on the rooftop of Onigashima, Luffy realizes that the strongest fighters don't just "blast" Supreme Haki—they infuse it into their physical attacks.

In Episode 1028, titled "Surpass the Emperor of the Sea - Luffy Strikes Back with an Iron Fist," Luffy begins coating his fists with Conqueror’s Haki. This "Advanced" technique allows him to damage Kaido without even making physical contact, marking his transition into the top tier of the world's strongest warriors.

Answer to Your Question

Luffy uses his "Supreme King" Haki (also known as Conqueror's Haki) at various points, but he uses the advanced form—often called Advanced Conqueror’s Haki or Infusion—in Episode 1014 during his fight against Kaido.

If you are referring to the first time he uses the basic "Knockout" version of Conqueror's Haki, that occurs during the Marineford Arc (Episode 478), where he unknowingly knocks out the executioners preparing to kill Ace.

1. Introduction: The Terminology Problem

The term "Supreme King Haki" likely originates from a fan translation or confusion with Haoshoku (覇王色, "Supreme King/Conqueror Color") itself. In Japanese, Haoshoku Haki literally means "Supreme King Color Haki." Thus, referring to a technique as "Supreme King Haki" is redundant—it would be like calling a specific sword swing "Samurai Sword."

The correct canonical hierarchy, as established by Silvers Rayleigh and detailed in Vivre Card databooks, is:

• Base Haoshoku Haki: Overwhelming weak-willed individuals.
• Advanced Haoshoku Haki (Infusion): Coating oneself or weapons with the invisible "pressure" of one's will to cause physical destruction without contact.

Luffy does not achieve the latter until the Wano Country Arc.

4. Gear 5 + Supreme King Haki – Episodes 1076–1077

• Luffy in Gear 5 (Awakened Zoan) uses Supreme King Coating casually.
• Feature: Ridiculous, cartoonish attacks (e.g., punching Kaido through the ground) that still carry the king’s will, affecting even Kaido’s durability.

1. First use – Episode 413 (Impel Down Arc)

• Context: Luffy faces the Wolves of the Sphinx (guards of Level 2 of Impel Down).
• Feature: Unconscious, uncontrolled burst. Knocks out a large group of enemies without knowing how he did it.
• Significance: Introduces the concept that Luffy possesses the quality of a king.

5. Phase 3: The Mastered Application – Episode 1074 ("The Fierce Battle of the Emperors! Luffy vs. Kaido")

• Manga Equivalent: Chapter 1013 (continued)
• Context: After recovering from being thrown off Onigashima, Luffy re-engages Kaido. This episode features the first extended, intentional use of Conqueror's Haki Infusion. Luffy's fists are perpetually coated in thick, trailing black lightning, and every impact creates a shockwave of invisible force that destroys the environment without direct contact.
• Key Visual Cue: Unlike Armament Haki (which is solid black), Conqueror's Infusion is distinguished by non-touching impact and lightning that does not emanate from a central point but flows with the attack.
• Dialogue Confirmation: Kaido says, "You're using it too?! Conqueror's Haki coating!"
• Verdict: This is the canonical answer to the fan question. If one insists on using the term "Supreme King Haki" to mean "the offensive use of Conqueror's Haki as a weapon," Episode 1074 is the first episode where Luffy does this deliberately and repeatedly.

6. Why the Confusion Persists: A Meta-Analysis

The misconception that Luffy used "Supreme King Haki" earlier (e.g., against Doflamingo in Episode 733 or Katakuri in Episode 870) arises from two errors:

1. Visual Pareidolia: Base Conqueror's Haki also produces black lightning upon emission. However, that lightning radiates outward and does not cling to the user's body. Fans conflated the two.
2. Scaling Assumption: Many assumed that because Luffy could damage Kaido only with a new Haki, that new Haki must have been used earlier against weaker foes. This is false; Infusion is a specific power-up unique to the Yonko-level combat of Wano.
