10 – KAKU/JABRA
Kaku ate the Ushi Ushi no Mi, Model: Giraffe, a Zoan-class Devil Fruit which allows him to transform into a giraffe-human hybrid and a full giraffe.
When in animal or animal/human-form, he can make further use of Rankyaku, as he gains two additional legs. The power of his Rankyaku is also increased, as seen when he uses Rankyaku: Amanedachi to slice through the whole tower that he and Zoro are fighting in.
Jabra ate the Inu Inu no Mi, Model: Wolf, a Zoan-class Devil Fruit which gives him the power to change into a full wolf and a human-wolf hybrid that resembles a werewolf.
This greatly increases his physical strength, allowing him to deal more damage with his Rokushiki techniques, which is further complimented by the sharp nails granted by his transformation. Being a carnivorous Zoan user, Jabra is more battle-adept than a regular Zoan.
9 – ROB LUCCI
Rob Lucci ate the Neko Neko no Mi, Model: Leopard, a Zoan-type Devil Fruit which allows him to transform into a leopard and a giant leopard-human hybrid. As Zoan class Devil Fruits enhance physical capabilities the most, it is most favored by martial artists like Lucci. Also, being a carnivorous animal, Lucci is more bloodthirsty and predatory than a regular Zoan class user. Fighting styles and abilities, like Rokushiki, are greatly enhanced by the power of the fruit.
8 – PAGE ONE/X DRAKE
Page One ate the Ryu Ryu no Mi, Model: Spinosaurus, an Ancient Zoan-type Devil Fruit that allows the user to transform into an spinosaurus hybrid and a full spinosaurus at will.
As a spinosaurus, he possesses tremendous strength, particularly in his jaws and tail, which are capable of effortlessly destroying buildings. In his hybrid form, his arms become long enough to use in combat and possess great strength as well, being able to overpower a kick from a Raid Suit-enhanced Sanji and send Sanji flying through several buildings.
X Drake possesses 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. 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, he acquires a strong biting ability that can even damage the heavy armor of the aforementioned Pacifistas, which are said to be stronger than steel.
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. In her hybrid and full-beast forms (most so in the latter), Ulti has the front part of her skull notably strengthened and hardened. 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.
