Hie Hie no Mi (HB)

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 the user into a Freezing Human (氷結人間 Hyōketsu Ningen?) Its name stems from the Japanese word "hiehie", which means "chilly". 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). It was eaten by former Admiral Kuzan, better known as Aokiji, Yet after his death it returned to circulation and is now eaten by Salazar D. Hyo.

Strengths and Weaknesses
This fruit's major strength is that it allows the user to turn himself, as well as his surroundings, into ice.

It is interesting to note that this fruit is one of the few Logia 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. However, most attacks are still ineffective against this fruit because its user can simply shatter and reform the ice composing them on impact.

Kuzan also has extreme amounts of resistance towards cold, due to his Devil Fruit's element, as he is able to freeze his body parts and turn back to normal without any tissue damage. The ice seems to cancel out with fire when they clash, as seen against Portgas D. Ace's Mera Mera no Mi. However, the ice seems to be ineffective against Whitebeard's vibrations, since the freezing powers against the great pirate failed due to the ice shattering before disabling the target. In addition, Akainu was able to melt the ice generated by Aokiji in seconds. However, it should be noted that Kuzan was able to fight against Sakazuki on equal terms for ten days.

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 contact his enemy directly to freeze them, yet Kuzan found ways like creating ice spears to extend his combat range. Kuzan is one of the few Devil Fruit users who is capable of counteracting his weakness against falling into water, as he can simply freeze it and create a surface to stand on, saving him from sinking and drowning.

Usage
For Kuzan's original use of the fruit, Please head to Hie Hie no Mi

Hyo's usage of the fruit is different from Kuzan's but not entirely, Hyo uses the fruit's ability of manipulating ice to create and shape ice in different forms such as a hammer, Drill, Sword etc, He has also mastered this fruit completely in a similar matter to Crocodile in which he can avoid damage by turning to ice reflexively, Hyo has also shown his capability into spreading himself into tiny shards of ice that look like snow flakes and because of that he can reform himself nearly anywhere around his enemy depending on where the ice shards are.

When he was injured by Busoshoku Haki and started bleeding, Hyo has shown his capability of freezing his own blood and using it as a weapon, He also froze his wound to stop the bleeding.

Trivia

 * In the anime, when the power was first introduced, the ice was white. During the Battle of Marineford, the ice had more of a blue color to it, matching up to Aokiji's nickname ("Blue Pheasant"). However, the color was still somewhat whitish, 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 the crew.
