The world of One Piece is filled with mystical power-granting fruits, known as the devil fruits. While not found often in the four blues, they're very common in the Grand Line, and almost every other pirate possesses one. The devil fruits are usually classified into three main types, namely, Paramecia, Zoan, and Logia types.
Each type is different from the others and offers a range of abilities such as turning into an element like fire or transforming into an animal. While they're not all equally powerful, they don't make any user weaker, as pointed out in the story itself. In this post, we'll be ranking the 10 rarest devil fruits in the world of One Piece.
10 Ope Ope no Mi
One of the Paramecia types, the Ope Ope no Mi is currently used by Trafalgar Law. This devil fruit gives its users the ability to create rooms, and control the terrain within the room as they like. As pointed out by Marine Vice Admiral Smoker, when in its range, the opponent is like a patient on an operating table.
The Ope Ope no Mi is powerful enough to switch people's personalities, and what's more, it can also make someone immortal by performing the perennial youth surgery on them, although the user will have to give up their life in return. The Marines put a price of 5 billion berries on this fruit, which shows how rare it actually is.
9 Yami Yami no Mi
One of the rarest devil fruits, possibly even among the logia class, the Yami Yami no Mi was eaten by Blackbeard. Using this devil fruit, he gained the power to control darkness as he likes. The biggest advantage of this devil fruit is its ability to nullify everything, even other devil fruit abilities, and maybe even Haki.
Although it appears to be invincible, one of its biggest drawbacks is that it takes away the user's intangibility as well, which makes it a double-edged sword. Nonetheless, it is considered to be the strongest and most rare logia type devil fruit.
8 Ryu Ryu no Mi, Model: Brachiosaurus
One of the many Ryu Ryu no Mi that have been introduced so far, the Brachiosaurus model of this devil fruit has been eaten by Queen the Plague of the Beasts Pirates. This devil fruit is one of the rarest fruits that we've seen in the series, thanks to its classification into the Ancient Zoans.
It grants one the ability to turn into a real Brachiosaurus, and since it is one of the zoans, the user also gets a high-level recovery, and superior stamina. Without a doubt, the Ryu Ryu no Mi Model Brachiosaurus is unique, and hopefully, more of its abilities will be revealed in the future.
7 Ryu Ryu no Mi, Model: Pteranodon
Another one of the subtypes of the Ryu Ryu no Mi, the Ryu Ryu no Mi, model: Pteranodon allows its user to transform into the ancient creature Pteranodon. Just like its other types, this devil fruit is classified as an Ancient Zoan, which makes it one of the rarest devil fruit powers on the seas.
The Ancient Zoan Pteranodon fruit was eaten by King the Wildfire, who is also the right-hand man of Kaido. While most of its powers remain a mystery, it is known to grant immense strength, as evident from when King pushed Big Mom's ship off the waterfall in Wano.
6 Mochi Mochi no Mi
The Mochi Mochi no Mi is a paramecia type of devil fruit that was eaten by the right-hand man of Big Mom, Charlotte Katakuri, at the age of 5. While paramecia types are considered to be the most common ones among all devil fruits, Katakuri's fruit is special, as it gives him the ability to act tangible, akin to a logia, hence making it a special paramecia devil fruit.
When used alongside Katakuri's ability to see into the future, he becomes almost invincible. So far, the Mochi Mochi no Mi is the only special paramecia that we've seen in One Piece, making it one of the rarest devil fruits of all time.
5 Inu Inu no Mi, Model: Kyubi no Kitsune
Eaten by the sixth ship commander of Yonko Blackbeard, the Inu Inu no Mi Model: Kyubi no Kitsune is treasured among all types of devil fruits. Its powers are ferocious, as it grants the user the ability to transform into any other person, replicating their entire appearance in the process.
What's more, this devil fruit is considered to be a mythical zoan type, which is even rarer than the logia types. Other than that, the Kyubi no Kitsune devil fruit also grants the ability to transform into a nine-tailed fox to the user, which is not an ability to be underestimated.
4 Hebi Hebi no Mi, Model: Yamata no Orochi
One of the many snake-snake fruits that we've seen in One Piece, the Yamata no Orochi version is considered to be the rarest out of them all. It was eaten by the Shogun of Wano, Kurozumi Orochi, and it grants him the ability to transform into an eight-headed serpent, each of which has its own personality.
As the name suggests, this devil fruit is one of the precious mythical zoan devil fruits, and thus the chances of anyone eating them are extremely low. If anyone does eat it though, they're likely to be gifted with one of the strongest abilities in the on the seas.
3 Hito Hito no Mi, Model: Daibutsu
Eaten by the former Fleet Admiral of the Marines, Sengoku the Buddha, the Hito Hito no Mi, Model: Daibutsu is a mythical zoan devil fruit as well. It gave Sengoku the ability to transform into a giant buddha, capable of releasing gigantic blasts of shockwaves from his palms.
As evident from its class, this devil fruit is unique and the skill that it grants the user in terms of raw strength, and recovery is staggering. Thanks to its powers, Sengoku has become one of the strongest marines of all time, even drawing comparisons to Garp the Hero himself.
2 Tori Tori no Mi, Model: Phoenix
Another one of the mythical zoans, the Tori Tori no Mi, Model: Phoenix is the devil fruit of the right-hand man of Yonko Whitebeard, Marco. Thanks to this devil fruit, Marco has earned the moniker of 'Marco the Phoenix'. Apparent by its name, this devil fruit gives Marco the ability to transform into a giant Phoenix.
Along with relatively high strength and stamina that Zoans possess, this devil fruit also grants one the special ability to regenerate from any wound within seconds using its 'blue flames of regeneration'. As such, it is a devil fruit without any weaknesses, and one of the most frightening ones that we've seen in the series. According to Kizaru, this devil fruit is even rarer than the fabled logia types.
1 Kaido's Devil Fruit
The Yonko Kaido of the Hundred Beasts has eaten a mythical zoan type of devil fruit that allows him to either transform into a dragon, or an Oni. It is unclear whether Kaido is a dragon who has eaten the Oni devil fruit or an Oni who has eaten the dragon devil fruit. Either way, he's likely eaten a mythical zoan devil fruit, which makes it unique in its own right.
Kaido's already abnormal strength is further boosted by this devil fruit, and it is largely responsible for him being known as the strongest creature in the world of One Piece. Certainly, it is glorious enough to top this list as the rarest devil fruit in the entire series.
