Hie Hie no Mi

The Hie Hie no Mi is a Logia-type Devil Fruit, eaten by Aokiji.

This fruit allows the user to turn himself, as well as things around him/her, into ice, and control it as well. It is interesting to note that this fruit is one of the few Logia that can be hit with a physical attack. However, they are still ineffective against this fruit because its user can simply shatter and reform the ice composing them on impact.

The meaing behind it's name: "Hiehie" means "chilly."

Weakness

Though this is yet to be demonstrated in the series, presumably extreme sources of heat and flame can counter this ability, as they melt ice.

Attacks

 * Ice Age (氷河時代(アイス･エイジ)): An attack used only near the ocean or other large area of water. Aokiji places his hand in the water, then in an instant freezes it (anything in/on it) completely solid. The actual extend of the ice can stretch for miles and last for over a week.


 * Ice Sabre (アイスサーベル): Aokiji picks up several thin objects, such as blades of grass, and throws them into the air. Then he blows on them with an icy breath that freezes them into a large, jagged, sword of ice.


 * Ice Time (アイスタイム): Aokiji touches his opponent's body then freezes them into a human ice statue. They can remain alive for some time in their icy form, but any decent hit will shatter them to pieces.


 * Ice Block Partisan (アイス塊(ブロック)「両棘矛」(パルチザン)): Aokiji creates several spears made of ice and then hurls them at the enemy.


 * Ice Time Capsule (アイスタイムカプセル): Using his powers, Aokiji slowly encases his enemy in ice. It is undetermined if the enemy is killed or simply frozen in place. However, the attack's name implies the latter.
