Top 10 Strongest Zoan Devil Fruits in One Piece

This is our list of The Top 10 Strongest Zoan Devil Fruits in One Piece.

#10- Hebi Hebi no Mi, Model: Yamata no Orochi.

This Mythical purple fruit caused a lot of issues, not only for non-fighters like Komurasaki but also for the talented Nine Red Scabbards. This is because it allows the user to become a giant and powerful Eight-headed Snake. In Japanese mythology, this creature is also considered a dragon, which explains the size, strength, and durability that it grants. Those eight independent heads make the user very hard to kill. In fact, the user needs to be decapitated a total of 8 times, in order to finally die. All Zoan fruits are known to enhance a person’s stats when they consume them.

 But this wasn’t clearly shown while Orochi was in human form since he focused instead on ruling with underhanded methods. His snake form is where his emphasis really shined. A single snakehead can lift a person, and stretch to attack people who are further away, and some of the heads can even be hidden to keep them from being cut off. Not to mention that if the heads attack at once, they can cover multiple directions, and cause a lot of destruction to the place they’re in.

It required all of the Nine Scabbards to work together just to cut off a majority of Orochi’s heads, and even then he still had one left to survive their fierce attack. On the other hand, the human form can still survive getting its head cut off. Kurozumi was the only character we saw with it, but since his death, it’s now back in the world and could be acquired by someone else with more fighting potential and experience. Possibly allowing it to reach its full potential.

#9 – Neko Neko no Mi, Model: Leopard.

Belonging to CP0 member, Rob Lucci, this leopard fruit grants the user the means to become a hybrid or fully-transformed feline. As for strength and durability, it’s comparable to an actual leopard’s feats and even surpasses them. Because of the animal that the user turns into, they gain more speed, agility, strong jaws, and teeth – as well as massive enhancements in jumping and climbing. Tobu Shigan “Bachi” is an attack that showcased the leopard’s strength well, as it was even able to pierce Luffy’s rubber body simply by flicking.

This is especially surprising since Shigan techniques usually involve directly jabbing someone. But full transformation allowed Lucci to attack by biting, just as a leopard would in the wild. To allow for more agility, the hybrid form can be modified further, but at the cost of losing some strength. This is only possible since Lucci mastered Seimei Kikan, a Cipher Pol technique for complete control of one’s body. Despite losing some combat power through this, Lucci gains more speed and can attack even faster, while also being less easy to strike down in this leaner size. Additionally, carnivorous Zoan transformations are usually more powerful than other ones related to animals, making this one twice as good.

Once awakened, this fruit provides another increase in size, strength, and a more agile body, plus a longer mane—which is more aesthetic than useful. An attack called Shugan has been revealed and was strong enough to stab Sentomaru’s emphasis substantially large body. Sentomaru is a veteran armament haki user, so he’s no pushover himself! Lucci was able to control the 5th form of his fruit, the awakened one, which could be partly because of his training as a government agent. We are about to get into the strongest ancient zone fruits in all of One Piece. 

#8 – Zou Zou no Mi, Model: Mammoth!

Currently belonging to Jack the Drought, this fruit lets the user become a gigantic Mammoth. As if the man himself wasn’t huge already! With a powerful trunk, Jack grows enormously in size, but it also makes him much slower. Because of that, it’s harder for the user to dodge incoming attacks quickly. Though trading speed for being able to break through buildings like an armored truck and leaving chaos in his wake is a pretty sweet deal. It also makes him durable enough to take attacks from multiple Minks in their Sulong form!

This is due to the Mammoth’s size, trunk, and thick legs. He doesn’t even need to use any named techniques! But if the user is tired of being slow, they still have the hybrid form. It’s more agile, smaller, and allows Jack to use his swords. This is because his hands are now free to attack or defend, while still having the stability of being on four legs – a case that’s unique to this Devil Fruit. It makes Jack into a mighty Centaur, rather than a leaner animal, like what usually happens with hybrid forms. And sure, there’s still the usual water problem, except that it’s remedied a bit by Jack being a Fishman; so he can still breathe and be awake underwater; he just can’t move around. Interestingly, Jack also has access to Armament and Observation Haki but chose to only use his Devil Fruit’s abilities in battle.

#7 – Ryu Ryu no Mi,

Model: Pteranodon, used by the mysterious King the Conflagration!

As the name suggests, this ancient Zoan can either make the user a hybrid or a full Pteranodon. With that comes an increase in size; but this time into a carnivorous, aggressive flying reptile. And as mentioned, being carnivorous gives Zoan users a leg up on some others. As for the increase in speed, it also applies to King’s flying, with his tough flesh getting a boost in strength as well. Not to mention, the fear of falling into the water is considerably less since the user can just fly over it with their wings.

Plus, these speedy and powerful wings, through enhanced hardness, can be used as weapons, to slice and strike—even when only partly transformed. In full Pteranodon form, King can use his head as a weaponized slingshot, apparently mimicking how the dinosaur used to do so in prehistoric times—at least according to his own theory. This technique called Tempuraudon caused trouble for even Zoro, who was able to damage Kaidou with an attack of his own. And he becomes strong enough to even damage ships by bashing into them. If that isn’t enough, King specifically can rely on his rare Lunarian Blood to enhance his Devil Fruit attacks by creating more fire than he already had. For example, shooting flames at his enemies while flying. Or when he tried to slice through Sanji with his sharp beak, only failing due to the cook’s Germa Raid Suit.

#6 – Artificial Version of Uo Uo no Mi, Model: Seiryu.

This is an unusual entry, as the fruit was considered a failure by Dr.Vegapunk, not because of its strength but because it turns the user into the wrong color. Pink instead of Blue. This artificial devil fruit was eaten by Kozuki Momonosuke. Following the age and size of the user, the transformation increases accordingly. In other words, when Momonosuke is his childhood self, he’s a small, but quick, serpent-like dragon. But after being aged up, he becomes almost as large as Kaidou’s genuine version of the fruit.

Either way, Momonosuke can fly and float using something called Flame Clouds as footholds or glide through the air. He can also create and control these clouds with enough practice. A more advanced technique involves the user shooting out attacks called Bolo Breath from their mouth. With it, Momonosuke stood up to Admiral Ryokugyu aka Green Bull, and was able to burn through his wooden body, and helped protect Wano. 

Similarly, in that same giant dragon form, Momonosuke was able to harm Kaidou by biting into him. Overall, the techniques and strengths remain the same as the first Seiryu fruit, with Momonosuke’s age being a factor in the slight differences. But with time, he should master the Devil Fruit. His rare ability to hear the Voice of All Things in further combination with his massive dragon form could come in handy for calling Zunesha or other allies to his side.

#5 Inu Inu no Mi, Model: Okuchi no Makami!

Part of the Mythical class, this fruit allows the user to become a hybrid or full Ancient Wolf Deity. By dumb luck, the current user is Yamato, Kaidou’s child. The specific wolf the user turns into is the Guardian deity of Wano, meaning it has a reputation for strength and prestige in the nation’s history. Just like other Mythical Zoans, it greatly improves all base abilities (strength, durability, and speed), along with an additional boost due to it being a carnivorous canine god.

The wolf aspect gives stronger teeth and claws, even in hybrid form. The fruit also provides the user with a special ability. And in this case, it’s the creation of ice, which can be used without going into full-wolf mode. This is in direct contrast with the fire that Kaidou and Momonosuke’s fruits can produce. The user’s ice can be used offensively through a blast of icy wind named Namuji Hyoga; defensively as a shield, or even as armor to reinforce the user’s body, which Yamato calls Kagamiyama. 

While in purely human form, a technique called Mahoroba allows Yamato to infuse ice into their weapon and strike with increased power as ice spreads outward from their attack. On top of that, Yamato’s ice can be built into a dense wall and was used to hold back a blast that would have set off numerous bombs. As per usual, the hybrid form allows for more fluid movement and the ability to wield weapons. This was most notably seen when Yamato held their own against Kaidou in his infamously powerful half-dragon form while performing Himorogiri. It’s a spinning strike from above that creates enough momentum and ice to knock even an Emperor of the Sea down! 

When faced with Kaidou’s fiery breath, Yamato’s frigid blast didn’t disappoint and matched its power head-on, canceling it out. And that’s not even taking into consideration the three forms of Haki that Yamato can use along with Okuchi no Makami techniques. Maybe more transformations await this Devil Fruit in the future!

#4 – Tori Tori no Mi, Model: Phoenix!

With the help of this fruit, Marco the Phoenix turns into a Mythical Phoenix! Whether partially or fully, the transformation gives him wings and fierce talons—while also unlocking the ability to fly. One kick from his powerful Phoenix leg attack Ongle not only sent Queen away but also slashed his enemy’s face. Unlike other mythical Zoan powers, Marco demonstrated the ability to focus his transformation on specific parts of his body. This means he could keep his head human while having the rest of his body covered in flames or looking more creature-like.

As expected of mythical power, this fruit provides the user with a huge upgrade to their basic abilities, beyond what they already have from personal experience. Not to mention being able to use the legendary bird’s abilities, like wielding sharp talons to fight enemies and soaring above dangerous areas for scouting purposes. Due to being a mythical creature, blue flames can be used as well, which, in scientific terms, is always hotter than regular, red flames. In this case, though, this ability is called the Blue Flames of Regeneration since it works a bit differently.

What makes these flames so special is that they don’t burn or hurt others with the heat they create, unless the user chooses to. In fact, it seems they’re better suited to healing the user and their allies. Injuries like stabbings, shootings, and even the loss of limbs don’t trigger much of a reaction from the Phoenix user. One could even argue that it’s like feeling nothing at all, due to how fast the pain is undone with the regeneration. Even in human form, the healing still works, so long as the blue flames are out. Marco can also heal a large group of people at once by launching his flames to envelop them through a technique called Nashi no Tsubute.

This was a quick way to stop the spread of the Ice Oni virus, delaying its effects of it. But that’s not all there is to this fire. For one, the Phoenix fruit can also easily make parts of someone’s body intangible through the flames, as if they were a Logia fruit user. And this makes it more difficult to injure the user. Cloaked in the fire, Marco can also become a shield for people behind him by using Fujiazami, which was effective against fellow fire-user King. If the user is caught off guard, as Marco has been, the flames would need time to reactivate the healing properties, creating a delay to focus on the injury.

That’s when something like the untouchable fire shield comes into play! It can be used to trick the enemy into believing Marco is invincible. Sure, it uses a lot of stamina, but if done right, the user could essentially win a battle in no time. That’s not to say the fruit’s strength is anything to scoff at. In fact, Marco was able to hold back both King and Queen using his Phoenix form. And the flames can be used offensively as Marco did with his Bluebird attack that he launched at King.

#3 – Hito Hito no Mi, Model: Daibutsu!

Now, it may not be a dragon or a prehistoric beast, but having someone turn into a revered Asian figure must be pretty intimidating. This fruit transforms former Fleet Admiral Sengoku into a giant Golden Buddha aka a Daibutsu, (which is Japanese for a large Buddha statue). So not only is it massive and daunting, but being made of gold guarantees the user will be hard to take down, seeing as it’s metal. Too bad that technically, gold is one of the weakest metals. With the obvious change in appearance comes an increase in size and durability, as well as power.

From what we’ve seen, users of the Daibutsu fruit can use this golden form to send shockwaves or blasts at enemies with their palm, while also dwarfing their enemies with their size, not unlike many others on the list. This same attack was powerful enough to stand up to the incredibly strong tremors from the Gura Gura no Mi that Blackbeard acquired from Whitebeard’s passing—said to be the strongest Paramecia fruit in the world. 

The golden Buddha form certainly served Sengoku well over the years, as he became the Fleet Admiral, until his resignation. And perhaps it aided him in his battle against Shiki the Golden Lion of the Rocks pirates, as he worked alongside Garp, to capture the infamous pirate. Not to mention, even a certain rubber body couldn’t fully deflect the damage from Sengoku’s giant, golden attack. Maybe the brightness of the golden aura around the user also helps to distract or blind opponents. We can only hope to see Sengoku in battle again!

#2 – Uo Uo no Mi, Model: Seiryu!

This incredible runner-up is so strong that it was used to make an artificial devil fruit in hopes of recreating its magnificence. It was originally seen during the God Valley Incident – an event that was so important and controversial that it was erased from maps and history. During that time, Big Mom herself gave it to Kaidou, creating a debt that he had to repay due to its value and sheer power as an ability.

But what makes it so good?

Well, it enables the user to become a giant Azure dragon when in full transformation. The style of this reflects an Eastern-style dragon that looks more like a serpent, rather than the Western kind, which can usually stand on its hind legs. The hybrid form doesn’t lag behind, though. It adds scales to the user’s body and allows for more freedom of movement and tougher flesh, as well as horns and claws for attacking. Interestingly, this fruit also has a secondary hybrid form, which may be specific to Kaidou or a hint as to its peak being reached by him.

Either way, it makes him bulkier, with a more beast-like appearance than his other hybrid transformation. Considering it’s bigger, it’s likely that it offers more power than the slimmer hybrid form. What’s insane is that a roar from Kaidou can also pull electricity from the sky, casting lightning bolts down on whoever’s below. In full transformation, this fruit offers increased durability but also pseudo-flight and impressive speed despite its monstrous size. There’s honestly no comparison between this dragon and other transformations—it’s the absolute biggest, hands down.

Being that enormous makes the person an easy target for enemies and puts their allies at risk if they aren’t careful with their expansive movements. But even if you can see Kaidou coming, the dragon form won’t be easy to overcome. For example, his fruit allows him to use Bolo Breath to breathe fire from his mouth, something he can do with extreme ease, even while drunk. And with the use of Flame Clouds, which can be controlled at the user’s will, enables something like flight by staying in the air for extended periods of time. If that’s not enough, the Azure dragon form can also use and attack through their massive body and movements.

With a strong breath, Kaifu is created, sending out slicing wind blades; it was powerful enough to cut off Kikunojo’s arm. And Tatsumaki is produced through the dragon’s enormous body spinning, and creating tornadoes around him to pull enemies closer. Kaidou’s also been shown combining his electricity with the tornadoes to further back his opponents into a corner! 

Everything about Kaidou’s full transformation is made for fighting, including his sharp claws, sturdy tail, thick body, powerful breath, and even the tendrils coming out of his face. Back when Oden was alive, Kaidou used said tendril to grab him and throw him aside because it was just that strong. That’s not even mentioning the fire dragon, Kaien Daiko, that can be created as an accessory to his already terrifying form, and is hot enough to burn most things away. But, there’s always going to be someone stronger in the world, and that’s why this menacing dragon lost his place as a Yonko. But before we see which fruit is at the top, let’s take a moment to look at some other Zoans who could have made the list!

Honorable mentions Ryu Ryu no Mi, Model: Pachycephalosaurus is

An ancient Zoan fruit that Ulti ate made her into a 2-legged, plant-eating dinosaur with a very durable skull. The hybrid form enlarges the user, but the full form is even more massive. This dinosaur’s fighting style involves mainly headbutts, but it was weak to lightning attacks as shown by Ulti’s struggle against Nami, Big Mom, and also Zeus (who finally knocked her down).

Maybe the fact of it being a Vegetarian prehistoric creature transformation, and not a Carnivorous one, lowered its power level significantly. Not to mention, Ulti seemed limited in their attack styles with this fruit. Who’s-who Neko Neko no Mi, Model: Saber. As the name implies, the user can go full or part Saber-toothed tiger aka a Smilodon. With that come all the qualities of a predatory, giant feline, in addition to retractable claws and extremely sharp and durable fangs.

But the Smilodon’s tail proves to be a major weakness that enemies can exploit by pulling it or stopping the user’s movements. Who’s-who also relied on his allies to outnumber opponents, so it’s hard to say how strong the fruit would be on its own and in a different context.

Ryu Ryu no Mi, Mode l: Allosaurus was eaten by X Drake, and it’s an Ancient Zoan that turns someone into a carnivorous dinosaur called the Allosaurus. Naturally, they have sharp teeth and claws, which is good for close combat. And it’s even strong enough to bite through a Pacifista, which is somehow smaller than the Allosaurus and made almost entirely of metal. With X Drake’s whereabouts currently unknown, it’s hard to say if the fruit has been put back into circulation now, since the events on Wano.

The Inu Inu no Mi, 

model: Kyubi no Kitsune is Catarina Devon’s Nine-tailed fox fruit, which gives her all the abilities of someone who can become a fox spirit, such as becoming and sounding exactly like another person. But we still haven’t seen enough of this fruit to know its true strength or the extent of its powers.

#1- Hito Hito no Mi, Model: Nika!

Did you expect something else?

What could be above becoming a deity that’s been on the run for centuries?

Monkey D. Luffy gains the powers of Sun God Nika, though the fruit was deceptively classified as a Paramecia-type Devil Fruit named the Gomu Gomu no Mi. Already, we can tell that there is too much power involved if the World Government needed to fool everyone and hide facts from the world. It was eventually stolen by Shanks and mistakenly eaten by Luffy.

But prior to this, it was consciously “escaping” the World Government’s grasp for 800 Years. Zoan fruits are known to have a will of their own, but this seems like the strongest we’ve ever encountered— by a landslide. In base form, the rubbery person the user becomes can do everything rubber can. This even includes their internal organs becoming rubbery!

So their entire body can bend, bounce, be immune to electricity, inflate, twist, and stretch. What’s more is that the user becomes immune to most basic weapons, like bullets, hand-to-hand combat without the use of Haki, cannonballs, and even blunt weapons. And the main reason for that is that the rubber effect is permanently active and doesn’t require a transformation like other Zoan fruits.

It seems to even continue while the user is asleep, which we’ll get into in a moment. With a body like that, it allows for defense and offense within a wide range by reaching enemies further away through a far-reaching, stretched limb. The best example of this is the Gatling Gun technique, a flurry of hits aimed at an enemy. In terms of protection, if the user inflates their body, it can be used as an airbag to slow or dampen blows. Luffy used an enhanced version, called Gigant Fusen to protect himself from Sengoku during Marineford. Luffy’s also been shown saving people by grabbing them at a distance or pulling them to him. And this is just the bare minimum.

As Luffy became more proficient, he unlocked different levels of power, which he refers to as Gears.

The starting point is the first.  Then we have Gear Second, which immediately enhances the user’s speed and mobility. This is done by increasing blood flow and sucking up more energy. Because of that, it can sometimes leave Luffy completely drained after a fight, possibly chipping away at his lifespan! But so long as he eats enough food, his body can bounce back. And with more experience, Luffy was able to cut down the amount of time he used this gear. 

Gear Third is a bolder technique involving air being blown into limbs to increase attack strength. Luffy uses this when he needs pure power, inflating his bones to make it even harder to counter him. On the other hand, the massive size that his limb gains makes him slower while also making him shrink once he’s done using it. With time, Luffy found a way to increase his mobility by focusing on where the air was on a single part of his arm. And he doesn’t turn into a mini-man anymore!

The Gear Fourth transformation involves his entire body, turning him into Boundman. Not only does he look and sound like a sumo wrestler, but he has insane mobility and speed thanks to coiling his muscles like springs and covering most of his body in Armament Haki. The speed and defensive capabilities are seriously off the charts, depending on which form he takes, Tankman or Snakeman. Snakeman is a much leaner form, like a hybrid-animal transformation. But like with Gear Second, it takes a lot out of Luffy and requires him to eat an unholy amount of food. All of these can be combined with the use of Haki, including Conqueror’s, as well as the extremely rare Voice of All Things!

And then there’s Gear Fifth!

Once the Devil Fruit’s fully awakened, the user can transform to match their imagination within reason, due to becoming a Warrior of Liberation. Unlike other transformations, which involve animal themes, this one makes the user’s hair and clothes change to white, and their eyes become red. The most striking thing, as proof of the awakening, is the white clouds surrounding Luffy, making him look like a Greek deity.

This makes sense if Nika is inspired by Nike, the winged goddess of victory. An awakened user can extend their rubber abilities beyond their own body just by touching something or someone and provides unpredictable attacks and changes to confuse the enemy in comedic ways. According to the ever-informed Five Elders, this is the most ridiculous power in the entire One Piece world! Like with other forms, there’s a bit of a downside: using Nika’s power draws out a lot of energy, probably because of how powerful it is. It’s as if two fruits were combined in one, though! Plus, Luffy’s only just started using this awakening and definitely can find ways to combat the side effects—just like he has with all the others.

And who knows? Maybe there’s a Gear Sixth coming down the line.
