Model: Archaeopteryx 

^{(Bird-Bird Fruit, Model: Archaeopteryx)}

_{^{Archaeopteryx was generally accepted by paleontologists and popular reference books as the oldest known bird. Archaeopteryx lived in the Late Jurassic around 150 million years ago with the largest individuals possibly attaining the size of about two feet in length. This fruit allows the user to transform in full or hybrid Archaeopteryx at will. As with other Ancient Zoans, this fruit’s transformation bestows greater strength and durability than regular Zoans. While in full Archaeopteryx form granted by this fruit the user gains animalistic strength, flight, sharp teeth and claws, and a long bony tail. Being a prehistoric predatory bird, the Archaeopteryx is better adapted for combat than normal Zoans. Otherwise, the user is affected by the standard Devil Fruit weaknesses.}}
