One Piece Wiki

The Hie Hie no Mi is a Logia-type Devil Fruit that allows the user to create, control, and transform into ice at will, turning them into a Freezing Human (氷結人間 Hyōketsu Ningen?). It was eaten by Kuzan, better known as former Admiral Aokiji.[4]


  • "Hiehie" (冷え冷え/ひえひえ?) means "feeling chilly/cold" in Japanese.
  • In the Viz Manga, it is called the Chilly-Chilly Fruit (not to be confused with the Samu Samu no Mi, also called the Chilly-Chilly Fruit by Viz).
  • In the English dub of the anime, it is called the Ice-Ice Fruit to more directly denote the fruit's element.

Strengths and Weaknesses

Kuzan freezing a whole sea bay in seconds.

As a Logia, this fruit allows its ability user to transform into the element of ice, as well as create and control it on a potentially massive scale, especially to freeze their surroundings. Particularly potent even by Logia standards, with this power running for a ten-day battle it was strong enough to permanently warp the very climate of one half of an island into a frozen, uninhabitable wasteland.[5] The Hie Hie no Mi's power is considered a superior counterpart to the Yuki Yuki no Mi's, ice being a superior freezing agent to snow.[6]

While other Logia fruits give their users the ability to dissipate out of harm's way by turning into their respective elements, it is interesting to note that this fruit is one of the few Logia fruits that can be hit with a physical attack. This is mainly because ice is a solid-state element, and thus, the user cannot simply dissolve out of harm's way as most Logia-users can with their fluid bodies, and it is slower in terms of reforming the body when damaged.[7] However, most attacks are still ineffective against this fruit because its user can simply shatter and reform the ice composing them on impact.[8] It's also apparent that the user can control the ice in his body to mold it and change its shape, as seen when Kuzan formed a hole in his chest before Whitebeard stabbed through Kuzan with his bisento, allowing Kuzan to avoid contact with the Haki-infused weapon.[9]

The user can instantly freeze anything that comes in contact with them, whether the user grabs onto the foe or the foe makes contact with the user's body. If the frozen area is not treated properly and immediately, then the resultant frostbitten areas will suffer permanent tissue damage.[10] If a body is frozen entirely, the victim can survive for a certain period of time, and can be saved if thawed out carefully, but will be left in a very brittle form that will result in instant death if shattered.[11] In order to thaw properly, the victim's body must generate heat internally, by putting low-temperature water onto it continuously until defrosted, and then massage the frozen area; if external heat is applied, it will cause the frozen tissues to crack.[12]

Kuzan's ice being counteracted by Ace's fire.

Kuzan has resistance towards cold, due to his Devil Fruit's element, being able to move around in cold environments with barely any protection. The ice seems to cancel out with fire when they clash, as seen against Portgas D. Ace's Mera Mera no Mi.[13] However, the ice seems to be ineffective against Whitebeard's earthquake abilities, since the freezing powers against the great pirate failed due to the ice shattering before disabling the target; the vibrations from the Gura Gura no Mi also shattered the ice and kept Whitebeard from being frozen solid.[14] In addition, Akainu's magma abilities were able to melt the ice generated by Kuzan in seconds.[15] However, it should be noted that Kuzan was able to fight against Akainu on equal terms for ten days straight.[16]

Kuzan is also able to travel great distances and move at high speeds by turning his entire body to ice, as seen when he moved from his seat on the execution platform into the air to freeze two tsunamis created by Whitebeard.

Most of this Devil Fruit's attacks require Kuzan to be in physical contact with his enemy directly to freeze them, yet Kuzan has found ways to extend his combat range, such as creating ice spears or ice tridents. Other than that, the user is also vulnerable to the standard Devil Fruit weaknesses. However, with the power over ice, this grants the user one of the few known powers capable of counteracting the standard Devil Fruit weakness of falling into water, as they can simply freeze the liquid and create a surface to stand on, thus preventing sinking and drowning.[17]


Kuzan leaving a target frozen solid.

The main usage of this fruit's powers, as demonstrated by Kuzan, is for combat. With the immense power over ice, Kuzan can create ice weaponry or freeze his opponents with physical contact. He can create enough ice to freeze a giant,[18] a Sea Beast,[19] and convert a massive amount of seawater into a gigantic ice sheet within mere moments. He was even able to freeze two tsunamis (giant enough to dwarf the Marineford fortress) brought upon a seaquake from Whitebeard's Gura Gura no Mi.[20]

Kuzan fighting with ice weaponry.

His main style of combat is to use his ice powers to disable and immobilize enemies, freezing their bodies solid just by touching them, and threatening to shatter their fragile forms, whether by touching them directly or with extensions of ice pillars. His other main style is to create weapons of ice to spear his opponents, to compensate his otherwise necessary direct contact. He can also use ice to cause discomfort to his opponents.[21]

Another usage of his ice that Kuzan demonstrated is for transportation across the ocean. He either freezes a large portion of the sea for other people to walk across, or create a narrow track of ice for him to ride over with his bicycle, the Ao Chari. Kuzan is one of the few Devil Fruit users who has shown to adapt his powers for traveling over the sea.[3]

After losing his left leg to Sakazuki in their battle for the position for Fleet Admiral, Kuzan used this fruit's powers to create a prosthetic leg out of ice.[22]


Ice Age.

  • Ice Age (氷河時代アイスエイジ Aisu Eiji?, literally meaning "Ice Age/Glacial Epoch"): An attack only used near a large area of water, such as the ocean. Kuzan near instantly freezes the water solid, along with anything in/on it. He can utilize this attack by either directly placing his hand in the water, or by extending a pillar of ice from his hand and into the water.[20] This attack can used on a very huge scale; the ice can stretch for miles and form an extremely thick sheet lasting for over a week before it starts to melt. Ice Age was first seen used by Kuzan to flash-freeze a massive expanse of ocean for Tonjit and Shelly to travel through the Long Ring Long Land.[19] This technique keeps its original name in the FUNimation dub.

Kuzan creates "Ice Saber".

  • Ice Saber (アイスサーベル Aisu Sāberu?): Kuzan creates a large, jagged sword of hard ice, capable of clashing with actual steel swords. When first seen using this technique (in an attempt to slash Nico Robin, but having the blade deflected by Roronoa Zoro and Sanji), Kuzan picks and throws up several blades of grass to blow on with an icy breath, thereby freezing them into the sword shape.[23] Later during the Summit War, Kuzan creates the blade without said preliminary, simply extending it from his body to swiftly stab Luffy.[24]

Kuzan uses "Ice Time" on Luffy.

  • Ice Time (アイスタイム Aisu Taimu?): Kuzan touches his opponent to freeze them into a human ice statue. The victim in question can remain alive in their icy prison for some time, in a state of suspended animation, but any decent hit will shatter them to pieces. This ended up being partly the case for Jozu, whose right arm broke off at the shoulder upon falling over while completely frozen.[25] If the ice is melted quickly and carefully though, a victim can return to normal without lasting repercussions.[26] However, the ice can also be shattered from the inside out, shown when Donquixote Doflamingo almost immediately broke loose from being frozen; this, however, was mentioned by Buffalo to be due to his heart not being frozen, and Kuzan had not been in direct contact with Doflamingo when freezing him.[27] Ice Time was first seen used to freeze Nico Robin.[28] The technique keeps its original name in the FUNimation dub.

Kuzan forming the "Ice Block: Partisan"; this is the more refined version.

  • Ice Block: Partisan (アイスブロック 両棘矛パルチザン Aisu Burokku Paruchizan?, literally meaning "Ice Mass: Two Thorn Pikes"): Kuzan creates several spears of ice by solidifying the cold air around him and then launches them at the enemy. When used against Saul, they were rather thin, and he only used two;[18] against Whitebeard, during the Summit War of Marineford 20 years later, the spears were noticeably more refined in shape, and more numerous.[29] This attack was first seen used in a flashback, to stop Jaguar D. Saul from escaping Ohara. A "partisan" is a type of polearm that was used in medieval Europe. This is called Ice Block Phalanx in the FUNimation dub of Unlimited Adventure.
  • Ice Time Capsule (アイスタイムカプセル Aisu Taimu Kapuseru?): Using his powers, Kuzan sends a wave of ice along the ground. Anything it hits is frozen in place. The technique was first seen being used in a flashback, against Saul.[30] A "time capsule" is a container storing a selection of objects chosen as being typical of the present time, buried for discovery in the future.
  • Ice Ball (アイスBALLボール Aisu Bōru?): Kuzan freezes his opponent in a giant sphere of ice from a distance. It was first seen against Whitebeard in the Summit War, but the attack failed due to Whitebeard generating vibrations around himself, causing the ice to shatter before it could freeze him truly solid.[14] In the FUNimation subs and dub, it keeps its original name.

The Ice Pheasant as seen in the anime.

  • Ice Block: Pheasant Beak (アイスブロック 暴雉嘴フェザントベック Aisu Burokku: Fezanto Bekku?, literally meaning "Ice Mass: Raving Pheasant Beak"): Connecting to, possibly being the source of, Kuzan's epithet, Kuzan releases a massive wave of ice in the shape of a pheasant in a single blast. This attack was first seen clashing against Portgas D. Ace's Kyokaen, the two attacks clashing and canceling each other out. It should be noted that in the manga, only half of the pheasant, its wings, were visible in the panel showing it because Ace had already melted the head portion of the bird's form with his firewall.[31] However, the pheasant was fully seen in the anime, as though Kuzan created a living pheasant out of ice, complete with flight capability.[32] The VIZ Manga translates the attack's name as Ice Block: Pheasant Peck, while in the FUNimation dub it keeps its original name.

Non-Canon Techniques

Video Game Techniques

  • Ice Pick (アイスピック Aisu Pikku?): Kuzan launches an ice dart at his opponent. This attack was shown and named in One Piece: Pirate Warriors.[33]
  • Ice Block: Avalanche (アイスブロック アバランシュ Aisu Burokku: Abaranshu?, literally meaning "Ice Mass: Avalanche"): Kuzan freezes water moisture from above into a giant block of ice, and then drops it down onto his target. This attack was shown and named in One Piece: Pirate Warriors.[33]
  • Ice Star (氷星アイス スター Aisu Sutā?): Kuzan leaps into the air and sends down a blizzard that freezes his opponents, then forms a wide-scale Partisan hailstorm to finish his opponents. This attack was shown and named in One Piece: Pirate Warriors 2.[34]

SBS Techniques

  • Ice Nail (アイスネイル Aisu Neiru?): When asked to draw the admirals genderswapped, Kuzan's female counterpart used this technique to make fake nails.[35]


  • In the anime, when the Hie Hie no Mi's power was first introduced, the ice was white. During the Summit War of Marineford, the ice had more of a bluish hue to it, more matching up to Kuzan's nickname ("Blue Pheasant"). However, the color was still more white than blue, which allowed Mr. 3 to use his wax to blend in with the ice, such as creating covers for Buggy and creating a clone of himself to fake being frozen along with the rest of his crew.
  • Unlike the other admirals, Kizaru, Akainu and Fujitora, who named all of their techniques in Japanese, Kuzan names his attacks in English instead.
  • According to a fan question, it is possible to make kakigōri (a Japanese shaved ice dessert) out of Kuzan, but eating it may cause him to take over from inside the stomach.[36]
