Kori Kori no Mi

Kori Kori no Mi (氷氷の実 Ice Ice Fruit) 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). It was eaten by Minerva, better known as Admiral Rozuryu.

Strengths and Weaknesses
The fruits major strength is it's ability to transform the user into ice, as well as the ability to create ice from nothing and control pre-existing ice. 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. However, most attacks are still ineffective against this fruit because its user can simply shatter and reform the ice composing them on impact.

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 anywhere on the body. If the frozen area is not treated properly and immediately, then the resultant frostbitten areas will suffer permanent tissue damage. If a body is frozen entirely, the victim can survive for a certain period of time, and can be saved if thawed out, but will be left in a very brittle form that will result in instant death if shattered. 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.

Minerva also has extreme amounts of resistance towards cold, due to her Devil Fruit's element, as she is able to freeze her body parts and turn back to normal without any tissue damage. She is also able to travel great distances and move at high speeds by turning her entire body to ice. Minerva is one of the few Devil Fruit users who is capable of counteracting her weakness against falling into water, as she can simply freeze it and create a surface to stand on, saving him from sinking and drowning.

Usage
The main usage of this fruit's powers, as demonstrated by Minerva, is for combat. With the power to manipulate ice, Minerva can create weapons of ice or freeze her opponents with physical contact. She can even use her ice powers in unison with her swordplay. With a single slash of her blade, she can create several dozen giant shards of ice. Her main style of combat includes freezing her enemies whether it be freezing a single target's body, or trapping several targets in a giant boulder of ice. She is also capable of creating ice weapons to compensate her otherwise necessary direct contact
