Zoan-type Devil Fruits are some of the strongest and rarest tools in One Piece – and its users are just as powerful.

Devil Fruits are one of the two major power systems in One Piece. Zoan-type Devil Fruits give their user the ability to transform into some type of animal, and they can assume a hybrid form that significantly boosts all of their physical abilities. There are also special types of Zoan Devil Fruits that are based on prehistoric creatures and mythological beings. There are dozens of Zoan-type Devil Fruit users in One Piece, but some are much stronger than others.

Many of the strongest Zoan users are affiliated with the Beast Pirates, and most of them now possess bounties well over 500 million berries. The majority of these individuals have the power of an Ancient or Mythical Zoan. Those who have awakened their Zoan-type Devil Fruit are typically even stronger.

As a member of the Flying Six, Ulti is one of the Beast Pirates’ strongest fighters. She could turn into a Pachycephalosaurus and assume a hybrid form because she ate the Dragon-Dragon Fruit, Model: Pachycephalosaurus. As an Ancient Zoan user, Ulti gains incredible physical strength, durability, and healing.

Ulti typically charges into her opponents and headbutts them, and she coats her forehead with Armament Haki. This attack allowed her to clash with and overpower Luffy’s Armament Haki. She can withstand a direct hit from Yamato, and she can survive a beam attack from Big Mom that combines the power of her Hera, Prometheus, and Napoleon Homies.

10 Zoan-Type Devil Fruits That Would Be Perfect For The Beast Pirates in One Piece

The Beast Pirates are a terrifying pirate crew that could do even more damage in the New World with One Piece’s best Zoan Devil Fruits.

Rob Lucci may have appeared before the timeskip, but he is still one of the strongest opponents that Luffy has ever faced. He ate the Cat-Cat Fruit, Model: Leopard – which allows him to transform into a leopard or leopard-human hybrid. Since the Devil Fruit is based on a predator, it is better suited for combat.

Lucci is one of the World Government’s top Cipher Pol agents, and he has mastered all seven Rokushiki martial arts techniques. Since the timeskip, Lucci has acquired both Observation and Armament Haki. He has also achieved Devil Fruit awakening. While in this form, Lucci becomes bigger, leaner, and far more powerful. He was able to briefly match Luffy’s Gear 5 transformation – but that was more Luffy holding back.

Queen is a scientist who specializes in cybernetics and virology, but he is also a strong fighter who achieved Yonko Commander status. He invented Excite Bullets, and he can use them to infect dozens of people with viruses that are painful and highly contagious.

Queen can turn into a Brachiosaurus because he ate the Dragon-Dragon Fruit, Model: Brachiosaurus. This Ancient Zoan gives him incredible strength and durability. Queen augmented his body with cybernetic enhancements, and he can now fire deadly lasers from his mouth and tail. If he grabs someone with his tail, he can crush their insides even if they are skilled Haki users. If Sanji had not awakened his superhuman genes, Queen would have likely killed him.

The 10 Strongest One Piece Swordsmen Who Are A Part Of A Yonko’s Crew

One Piece Yonko’s are the rulers of the new world and they have many skilled swordsmen at their disposal.

King is Kaido’s right-hand man, which means he is the second strongest member of the Beast Pirates. As a member of the Lunarian race, King possesses the innate ability to create fire, and he has a pair of large fully functional black wings.

King can transform into a Pteranodon because of the Dragon-Dragon Fruit, Model: Pteranodon. When using his Hybrid form, King’s flying speed increases significantly, and he can perform a beak attack that Zoro admits is impossible to block. His Armament Haki can match Zoro’s, and he can perform large-scale fire attacks with his sword. Zoro would have likely lost to King if he had not awakened his Conqueror’s Haki.

Yamato debuted in the later stages of the Onigashima Raid, and fans were shocked to learn that he is Kaido’s son. He has inherited some of Kaido’s superhuman physical abilities, and he is capable of using all three types of Haki. He is also one of the few people in the world who can infuse objects with advanced Conqueror’s Haki.

He ate the Dog-Dog Fruit, Model: Okuchi-no-Makami. This Mythical Zoan gives Yamato the ability to transform into a divine wolf that can generate ice beams and ice-based defenses. While Luffy was incapacitated, Yamato and Kaido fought each other in their hybrid forms, and Yamato was able to fight him for a time.

Sengoku was the Fleet Admiral of the Marines during the Summit War, and he is still considered one of the strongest characters in One Piece despite being in his late 70s. He ate the Human-Human Fruit, Model: Buddha – a Mythical Zoan that gives him the power to transform into a large golden Buddha.

While in this form, Sengoku can perform powerful shockwaves that are strong enough to send most of the Blackbeard Pirates flying. These shockwaves can clash evenly with the Tremor-Tremor Fruit – which supposedly has the power to the destroy the world. Sengoku can use all three types of Haki, and other than Garp, he was the only Marine that Gol D. Roger found worthy of his time.

The 25 Highest One Piece Bounties Ever

One Piece features a ton of loveable pirates, but only a select few have drawn the attention of the World Government enough to earn a high bounty.

Marco revealed the Bird-Bird Fruit, Model: Phoenix during the Marine Ford Arc. It is one of the only Devil Fruits that gives its user the ability to fly freely. He can transform into a firey blue phoenix, and the flames of this Mythical Zoan have incredible healing properties. Marco can heal most injuries in a matter of seconds.

When Marco joined the Whitebeard Pirates, he was just an apprentice, but he went on to become the commander of the first division. He could fight on par with Admiral Kizaru because of his Devil Fruit and Haki. During the Onigashima Raid, he was able to fight King and Queen at the same time without sustaining any major injuries.

3Kaido Is Considered The Strongest Creature In The World

Prior to his defeat, Kaido was one of the Yonko, and he was considered the strongest creature in the world. His body is nearly indestructible, and he can increase that durability with his Armament and Conqueror’s Haki. He ate the Fish-Fish Fruit, Model: Azure Dragon – which allows him to turn into a colossal dragon.

While in this form, Kaido can perform various elemental attacks, including a fire blast that can destroy an entire mountain. His hybrid form could match and overpower Luffy’s Gear 4 transformation. Kaido himself once admitted that Whitebeard, Shanks, Rocks D. Xebec, Oden, and Gol D. Roger, were the only individuals capable of actually beating him.

The Strongest Devil Fruits Introduced in One Piece’s Egghead Arc

As One Piece enters its final saga with the Egghead arc, fans will see some of the strongest Devil Fruits yet.

If Luffy wants to achieve his dream, he will need to surpass the Five Elders – who were once recognized as the highest authorities of the World Government. Saint Jaygarcia Saturn holds the Warrior God of Science and Defense title, and he reveals his unnamed Mythical Zoan Devil Fruit during the Egghead Buster Call.

He can transform into a spider-like oni, and he has clearly awakened his Devil Fruit’s power. Saturn can immobilize others by simply looking at them, and he can injure certain opponents in the same way. Those with weak Haki die if they simply look at him. He can regenerate entire limbs very quickly, and he does not seem to be negatively affected by Luffy’s Gear 5 abilities.

For the majority of the series, Luffy’s Devil Fruit was classified as a Paramecia, but that is because the World Government concealed its true name. The Human-Human Fruit, Model: Nika is a Mythical Zoan that turns Luffy into an incarnation of Nika – a playful sun god with a rubber body.

Luffy can barrage opponents with high-speed punches, and he can enlarge his limbs to deal massive blows. He is one of the few people who can use all three types of Haki – including advanced Armament and Conqueror’s Haki. He defeated Kaido and other powerful pirates like Crocodile, Doflamingo, and Charlotte Katakuri. Gear 5 is his awakened form, and it allows him to fight with absolute freedom because he can treat anything he touches like rubber.
