Devil Fruit Type Info

Devil Fruit
The Devil Fruits are a food, brimming with energy and the power of the devil himself. It only takes one bite to absorb the effects of the fruit, which includes a special power, and the inability to swim. The effects of the devil fruit can be nullified by water (as mentioned before, seastone, or by Blackbeard's devil fruit powers (as recently known). In the case of Buggy, It is proven that you don't need to even bite or chew thew fruit for it to take effect. Only one type of fruit with the same power exist in the world (meaning only one Gomu Gomu fruit). So it is possible for two people to have the same power, but no more than that. These fruits are split up into three groups: Paramecia, Zoan, and Logia. Each fruit will be introduced more in their respective sections. Fruits are sorted by order of appearance.

Logia= This Type of Fruit contains the power of the elements. It grants the user the power to control the element, and even turn into it themselves.
Paramecia=This Type of Fruit alters the User's body in some way.Paramecia fruits can be divided into several subcategories, at it is impossible to generalize the powers. For instance, Luffy's Gomu Gomu fruit is always active, meaning that he's a rubber human at all times. Other users, like Miss Valentine or Miss Doublefinger must mentally activate the changes in their bodies, while again others like Foxy and Robin can't change their bodies at all.
Zoan=This Type of Fruit alters the User's body into the form of a certain animal. Zoan fruits can allow the user to change their forms, to original, animal(whatever type specified by the fruit), or a hybrid. The Straw Hat's doctor, TonyTony Chopper, invented a 'drug' called the rumble ball. It stimulates the devil fruit's effect on the body, and unlocks new forms. So far it can unlock 4 additional forms.
