The Ryu Ryu no Mi, Model: Allosaurus is an Ancient Zoan-type Devil Fruit eaten by X Drake, a member of the Worst Generation and a former Beast Pirates Tobiroppo.

This Devil Fruit allows Drake to transform into an Allosaurus or hybrid form, granting immense physical strength, durability, biting power, and combat resilience. As an Ancient Zoan, the fruit provides enhanced toughness and recovery beyond standard Zoans.

Drake uses this power extensively in direct combat and during large-scale conflicts, including events in Wano Country, making it one of the most prominent dinosaur Devil Fruits in the series.
