Currently, X Drake and his crew are affiliated with the Beasts Pirates, the pirate crew led by Kaido, one of the Yonko. X Drake serves as one of the crew’s Headliners and is one of the Six Flying Fighters, six of the strongest Headliners.
In Chapter 929 it is revealed that X Drake ate the Ryu Ryu no Mi, Model: Allosaurus, an Ancient Zoan Devil Fruit that gives Drake the ability to transform into an allosaurus hybrid and a full allosaurus at will.
The major strength of Drake’s fruit is that it allows him to turn into an allosaurus, a large and powerful predator from the prehistoric era. This makes this fruit well-suited for combat purposes, since carnivorous Zoans are said to be fiercer fighters than non-carnivorous ones.
While in full allosaurus form, Drake’s own size increases, making him bigger than a Pacifista, and he retains this size while in hybrid form. He is also granted a strong biting ability that can even damage the heavy armor of the aforementioned Pacifistas, which are said to be stronger than steel.
