Zoan

Zoan is one of the three Devil Fruit types. This type of Devil Fruit allows the user to transform into another species at will, or an inter-species hybrid. Zoan types are especially effective in close combat.

The term was first used when professor Titan was explaining the devil fruit system to Surge

Overview
Zoan-type Devil Fruits grant the user the ability to transform into another species. Zoan Fruits provide the user with three basic forms:


 * Human Form (人型 Hito-gata) The user's natural form prior to consuming the fruit.
 * Human-Beast Form (人獣型 Jinjū-Gata): A hybrid form, combining the characteristics of both the users original species and the fruit-bestowed species into an unusual form (usually in a bizarre way where the size is greatly exaggerated).
 * Beast Form (獣型 Kemono-gata): A form in which the user is fully transformed into the fruit-bestowed species.
