Zoan

Effect
Allows the user to transform into a animal. This fruit provides three forms: the user's natural form, a full animal form (where the animal's size is often greatly exaggerated), and a hybrid form, combining both original and animal form (usually in a bizarre way).

Strength
Mainly improves physical abilities and allows the user to use his or her 3 forms to adapt to a situation during a fight to find the form that gives the biggest advantage. In their hybrid form Zoan users experience enhanced senses as this form uses a combination of both animals abilities. This fruit type is most useful when applied to objects such as guns or swords, giving a otherwise inanimate object life and increasing its value to the owner of the item.

Weakness
They are limited to the capabilities of the animal they are able to transform into. However, in the case of the Human Human fruit (and most likely all cases with the Zoan Devil Fruit types), it is not totally wasted if the species consumes the fruit of the same nature. If a human ate the Human Human fruit, they would become enlightened.

Other information
While most Zoan users can only use the three forms, the Straw Hat Pirate's doctor Tony Tony Chopper can utilize more forms for a given amount of time with the aid of the "Rumble Ball", which he developed. It's unknown if other Zoan users can also be affected by the Rumble Ball since so far only Chopper ate the Rumble Ball. It was stated by Chopper that carnivorous Zoan are considerably more bloodthirsty than other Zoan. A majority of the Zoan Devil fruits also come in different "models" that result in variations of the animal. For example, the Inu Inu (Dog) Fruit has a Jackal model, a Dachshund model, and a Wolf model, the Ushi Ushi (Cow) Fruit has a Bison model and a Giraffe model, and the Neko Neko (Cat) fruit has a Leopard model.
