A Logia fruit that lets its user generate, command, and become ice. Eaten by the former admiral Kuzan, it can flash-freeze oceans, encase enemies solid, and reshape entire climates, making him one of the most devastating Logia users alive.
This Logia recasts its eater as a so-called Freezing Human, able to conjure, direct, and become ice across an enormous range. The power rests with Kuzan, the ex-admiral of the Marines who once went by Aokiji. Even measured against other Logia it stands out as remarkably strong: a battle lasting ten days against Akainu warped half of Punk Hazard forever into a frozen, lifeless waste. Fans consider it the upgraded twin of the Yuki Yuki no Mi, since ice freezes more effectively than snow does. Its name derives from hiehie, a word for feeling chilled to the bone.
Unlike fluid-bodied Logia who simply dissolve out of danger, ice is solid, so Kuzan can actually be struck; he compensates by shattering and reforming the ice that composes him on impact, and he can even open a hollow in his own chest to let a Haki weapon pass through. Any contact freezes the target instantly, and untreated frostbite leaves permanent damage. A fully frozen victim survives in suspended animation and can be thawed carefully with internal heat and cold water, but a sharp blow shatters them and kills them at once. His ice cancels out against fire, as it did with Ace's flames, and is melted in seconds by Akainu's magma, while Whitebeard's quake vibrations and Garp's overwhelming Conqueror's Haki both kept it from setting. The power also negates the usual water weakness, since Kuzan can freeze the sea into a surface to stand on, and he rebuilt a lost leg as a regenerating prosthetic of ice.
Kuzan is the fruit's user, and he weaponizes it for combat and travel alike. He freezes opponents on touch, raises ice spears and tridents to extend his reach, and can convert vast stretches of seawater to ice in moments, even halting tsunamis that dwarfed the Marineford fortress. Named techniques include Ice Age, a near-instant freeze of a huge body of water; Ice Saber, a jagged blade of hard ice; Ice Time and its ground-traveling Ice Time Capsule for sealing foes in living statues; Ice Block: Partisan, a volley of ice spears; Ice Ball; the pheasant-shaped Ice Block: Pheasant Beak tied to his Blue Pheasant epithet; and Ice Glove, a Haki-reinforced frozen punch. Notably, Kuzan names his moves in English while the other admirals use Japanese.

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....
The Hie Hie no Mi is a Logia-type Devil Fruit that lets its user generate, control, and turn into ice. It belongs to Kuzan, the former Marine admiral once known as Aokiji.
Unlike most Logia, the Hie Hie no Mi is solid rather than fluid, so Kuzan can actually be struck, though he compensates by shattering and reforming the ice on impact. His ice also melts against strong enough heat, such as Akainu's magma.
"Hie Hie no Mi" comes from the Japanese word hiehie, meaning chilled to the bone, and the fruit is rendered in English as the Ice-Ice Fruit.
The Hie Hie no Mi lets Kuzan freeze anything on contact, raise ice spears and tridents, convert vast stretches of seawater to ice in moments, and even regrow a lost leg as a regenerating ice prosthetic.
Kuzan's named techniques include Ice Age, a near-instant freeze of a huge body of water, Ice Saber, a jagged ice blade, Ice Time and Ice Time Capsule for sealing foes as living statues, and Ice Block: Pheasant Beak, tied to his Blue Pheasant epithet.
