Yuki Yuki no Mi

The Yuki Yuki no Mi is a Logia-type Devil Fruit that allows the user to create, control, and transform into the element of "snow" at will. "Yuki" (雪) means "snow". It was consumed by Monet.

Strengths and Weaknesses
This fruit's major strength is that it allows the user to turn herself into snow. Monet also has extreme amounts of resistance, if not immunity, towards cold, due to her Devil Fruit's element, like Kuzan's Hie Hie no Mi powers. While the two Devil Fruits have similar abilities, there are two major differences between this fruit and that of the Hie Hie no Mi: Monet's intangibility for snow is not a solid form element unless it has been compressed, and unlike Kuzan, Monet cannot directly freeze her target solid.

As a Logia, Monet can let physical attacks pass through her without injury and can only be wounded with the use of Busoshoku Haki, Kairoseki, and, in her unique case, heat. Her attacks can also be stopped if her body is broken apart before she can execute her attacks. Furthermore, she can also lose control of her body's transformations if she becomes mentally unstable, as shown when Zoro cut her in half non-lethally: Monet was so overcome by fear of what could have happened if Zoro had imbued Haki in his attack that she could not put herself together right away, leaving her vulnerable. Other than that, she is also vulnerable to other standard Devil Fruit weaknesses.

Usage
Monet's Logia power allows her to produce, control, and become snow. As a Logia she can turn herself into snow to avoid attacks by letting them pass through her, or by floating around attacks. She can manipulate the density of the snow to form solid snow barriers. These barriers are extremely hard, making it difficult to destroy them, but she can easily pass through her snow barriers, she also has the ability to weaken someone and make them lose consciousness by hugging them, using her cold body to sap their own body heat. By transforming into snow she can secretly hide in snowstorms, as seen when she followed Trafalgar Law through the ice lands without being noticed.

She can also release a massive snowstorm to take advantage of the cold to weaken her opponents in a similar way. She can also dive into the drifts from her snowstorm to move and attack quicker.

She can also transform herself into a huge snow monster. In this form, her bite is not only strong, but cold enough to freeze and break the afflicted body part.

Attacks

 * Kamakura (カマクラ): Monet forms a barrier of snow around a nearby person or object. The barrier is quite strong as it took Luffy several Haki-imbued punches while in Gear Second to break it. It was first used to protect Caesar from Luffy's surprise attack. "Kamakura" is a snow hut. In the Viz Manga, the move is known as Igloo.
 * Kamakura Jussoshi (カマクラ十草紙): Monet creates a snow hut with ten overlapping layers of Kamakura that cannot be easily broken. It was first used to trap Luffy, stalling him for more time to allow Caesar to escape. In the Viz Manga, this move is known as Ten-Layer Igloo.


 * Yuki Gaki (雪垣): Monet creates a solid snow wall. It can be used to block a doorway, as she did to stop Nami, Robin and Chopper from chasing after the children. It can be destroyed by a strong swordsman like Zoro who can slice steel.


 * Mannen Yuki (万年雪): Monet completely turns to snow and then proceeds to surround an opponent's body with the snow, weakening and immobilizing them with the severe cold she exudes. While the enemy cannot move, Monet then transforms into a large snow monster with long fangs made of solidified snow. The fangs can easily rip through flesh and bone, although the enemy does not bleed due to the wound freezing from the cold. However, if the victim manages to grab a hold of Monet while she's biting them, as shown by Tashigi when fighting her, she will not be able to tear off the afflicted body part, though she can still injure them further by biting harder. It was used against Nami and Chopper but stopped by Robin. It was later used on a G-5 Marine, taking a chunk out of his shoulder.


 * Tabira Yuki (たびら雪): Monet freezes feathers of her wings, transforming them into sharpened, solid snow-blades capable of clashing with Zoro's swords.
 * Hada Gatana (肌刀): After Tabira Yuki, Monet uses her wing to attack her enemy, slashing with it as if it was a sword.


 * Yuki Rabi (雪兎（ゆきラビ）): Monet swings her left wing to release numerous solid hardened snowballs with small rabbit-like ears, whiskers, and eyes. It was used against Tashigi, who easily dodged it with Soru.


 * Fubuki (雪嵐): Monet releases a stream of snow from her lips that quickly surrounds an enemy and traps them within a blizzard. It is very similar to Crocodile's Sables but it does not send people flying with this technique. This was first used against Tashigi.

Trivia

 * This is the first canon Logia fruit that has been eaten by a female character.
 * Fitting in with the mythical creatures theme on Punk Hazard, this Devil Fruit makes Monet similar to a Yuki-onna, a Japanese spirit depicted as a woman that lures travelers into blizzards and freezes them to death.
 * This fruit is similar to the Hie Hie no Mi as both are Logia Devil Fruits and both are related to cold temperatures.
