The Tori Tori no Mi, Model: Thunderbird is a Mythical Zoan-type Devil Fruit that allows a person to transform into a hybrid and a full thunderbird at will, making the user a Thunderbird Human (サンダーバード人間 Sandābādo Ningen). A "thunderbird" is a legendary creature that is from the belief that the beating of its enormous wings causes thunder and stirs the wind. It was initially eaten by Winters D. Jack but it later returned into circulation after Jack died and was eaten by his son Zeke.
