The Zoan Devil Fruit is a type of Devil Fruit in the One Piece universe that allows its user to transform into an animal or a hybrid form that combines human and animal traits. This transformation grants the user enhanced physical abilities, such as increased strength, speed, and agility, depending on the animal they can transform into. There are three main categories of Zoan Devil Fruits: standard Zoan, which allows transformation into a specific animal; Ancient Zoan, which enables transformation into prehistoric creatures like dinosaurs; and Mythical Zoan, which grants the ability to transform into legendary creatures from mythology. Each type offers unique powers and advantages in battle.
