#Ryu Ryu no Mi, Model: Spinosaurus
The Ryu Ryu no Mi, Model: Spinosaurus is an Ancient Zoan-type Devil Fruit that allows the user to transform into an spinosaurus hybrid and a full spinosaurus at will.
It was eaten by Page One, one of the Beasts Pirates Headliners and one of the Six Flying Fighters, six of the strongest Headliners.
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.
#Ryu Ryu no Mi, Model: Pachycephalosaurus
The Ryu Ryu no Mi, Model: Pachycephalosaurus is an Ancient Zoan-type Devil Fruit that allows the user to transform into a hybrid and full version of a pachycephalosaurus at will. It was eaten by Ulti, one of the Tobiroppo, the strongest six Headliners of the Beasts Pirates.
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.
#Inu Inu no Mi, Model: Kyubi no Kitsune
The Inu Inu no Mi, Model: Kyubi no Kitsune is a Mythical Zoan-type Devil Fruit that allows the user to transform into a nine-tailed fox.
It was eaten by Catarina Devon, one of the Ten Titanic Captains, and the captain of the Sixth Ship of the Blackbeard Pirates.
The greatest strength of this fruit is that the user is also capable of transforming into other people, allowing them to impersonate them. The clothing of the target person can also be imitated during the transformation.
#Tori Tori no Mi, Model: Phoenix
The Tori Tori no Mi, Model: Phoenix is a Mythical Zoan-type Devil Fruit which allows the user to transform into a phoenix hybrid and full phoenix at will.
It was eaten by the former 1st division commander of the Whitebeard Pirates Marco.
While this fruit’s power is classified as a Zoan, due to the uniqueness of the phoenix, the additional powers it grants may be considered similar to those of Paramecia (the somewhat “superhuman” power that affects the user’s body: regeneration) and Logia (the generation of blue phoenix flames).
This Devil Fruit gives the user increased physical attributes (as is with all Zoan types) and the rare ability of flight, as well as the possibility of launching aerial attacks.
The fruit’s greatest attribute, however, is that by transforming into a phoenix of blue flames at will, the user can regenerate any wounds with the blue fire they generate, much like how a phoenix is said to rise from its own ashes. In general, the blue flames neither burn nor spread as natural flames do and are merely warm, not hot, in themselves lacking potential for offense — regardless, due to their special nature they are superior in potency to normal fire, proven when Marco overpowered and caused pain to Prometheus, a “special” fire homie made from Big Mom’s soul.
These blue flames are not hot and they do not burn or spread like normal fire; instead, they are what allow the user to heal, though there is a limit to the regeneration and are referred to as the “Blue Flames of Resurrection”. Furthermore, the healing properties of the blue flames can also be used to treat other beings, albeit to a more limited extent, allowing Marco to act as an efficient doctor.
#Hito Hito no Mi, Model: Daibutsu
The Hito Hito no Mi, Model: Daibutsu is a Mythical Zoan-type Devil Fruit that allows its user to transform into a Daibutsu (a giant gold Buddha) at will. It was eaten by Sengoku, the former fleet admiral of the Marines.
The main strength of this fruit is that it allows the user to transform into a giant, living, golden Buddha, gaining an extreme boost in strength to match his size. In this form, Sengoku’s limbs grow out of proportion, giving him abnormally large arms and relatively tiny legs. His entire body takes on a solid gold hue, (grey color in Gigant Battle); in addition to a full and hybrid transformation that are available to all Zoan Devil Fruit users, he can use palm thrusts to launch powerful shock waves.
#Ryu Ryu no Mi, Model: Allosaurus
The Ryu Ryu no Mi, Model: Allosaurus is an Ancient Zoan-type Devil Fruit that allows the user to transform into an allosaurus hybrid and a full allosaurus at will. It was eaten by X Drake.
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.
#Ryu Ryu no Mi, Model: Triceratops
The Ryu Ryu no Mi, Model: Triceratops is an Ancient Zoan-type Devil Fruit that allows the user to transform into a hybrid and full version of a triceratops at will. It was eaten by Sasaki who is one of the Tobiroppo, the strongest six Shinuchi of the Beasts Pirates, and leader of the crew’s Armored Division.
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.
