x Drake ate the Ryu Ryu no Mi, Model: Allosaurus, an Ancient Zoan-type Devil Fruit that allows the user 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, making him much better suited for combat than basic Zoans.
While in full allosaurus form, Drake’s own size increases, making him bigger than a Pacifista. 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. His tail is also a powerful weapon, capable of slamming people with great force. In hybrid allosaurus form, Drake becomes smaller, but still relatively large, and is capable of wielding his signature weapons for melee combat.
Page One ate from the Ryu Ryu no Mi, Model: Spinosaurus, an Ancient Zoan-type Devil Fruit allowing him to transform into a spinosaurus. He boasts tremendous strength in his full-beast form, particularly in his jaws and tail, able to effortlessly wreck buildings using them. In his humanoid hybrid form, his arms become long enough to use offensively and hold great strength as well, being able to overpower a kick from a Raid Suit-empowered Sanji and send the Straw Hat cook crashing through several houses. As an Ancient Zoan type, Page One has a high amount of durability, able to recover quickly from strong attacks dealt to him by Sanji in his Raid Suit and a Gear Third-using Monkey D. Luffy.
Ulti ate the Ryu Ryu no Mi, Model: Pachycephalosaurus, an Ancient Zoan-type Devil Fruit that allows her to transform into a full pachycephalosaurus and human-pachycephalosaurus hybrid at will. Ulti’s crewmates consider her full-beast transformation to be excessive force against most opponents, likely to cause great collateral damage, and she uses it against only those opponents she takes seriously.
When transformed, Ulti’s already immense physical power is increased further, to the point where she could grab hold of Luffy’s shoulders and thereby immobilize the pirate despite his own incredible strength. As a dinosaur, Ulti is much tougher when transformed than normal Zoan ability users, as exemplified by the woman quickly recovering from a full-on hit by Yamato’s Raimei Hakke, being only briefly rendered unconscious.
Sasaki ate the Ryu Ryu no Mi, Model: Triceratops, an Ancient Zoan-type Devil Fruit that allows him to transform into a full triceratops and triceratops-human hybrid at will. Like other Ancient Zoans, particularly dinosaur models, this fruit grants Sasaki an immense increase in physical strength, and he can charge into opponents with immense force, enough to knock back powerful figures.
Who’s Who ate the Neko Neko no Mi, Model: Saber Tiger, an Ancient Zoan-type Devil Fruit that transforms its user into a saber-toothed tiger, a powerful, carnivorous predator from the prehistoric era. Who’s Who, an already large man, grows to a much bigger size in his full-beast form, appearing to dwarf his subordinates and the large fish-man Jinbe.
Black Maria ate the Kumo Kumo no Mi, Model: Rosamygale Grauvogeli, an Ancient Zoan-type Devil Fruit that allows her to transform into a Rosamygale grauvogeli, a prehistoric carnivorous spider.
The user of this fruit gains the abilities of a spider, most notably the ability to shoot webs out of their body; these webs are strong enough to easily trap and capture even powerful fighters like Sanji. Additionally, the user can walk on walls and ceilings with their spider legs. Although the real-life Rosamygale grauvogeli was under a centimeter in size, this fruit’s transformation appears to be proportionate to the size of the user’s body, which in Black Maria’s case causes it to dwarf normal-sized humans.
