The Strongest Mythical Zoan Transformations in One Piece, Ranked

The Mythical Zoan Devil Fruit is known to be one of the rarest and most dangerous Zoans out there in the One Piece world. These abilities work very differently from a regular Zoan, since they come with godly or demon-like powers, and sometimes even the legendary powers of mythical creatures. As the story moves forward in the Final Saga, Eiichiro Oda keeps giving us more such new, powerful transformations.

So here we are listing down the Top 10 most powerful Mythical Zoan transformations in One Piece. From huge dragon transformations to reality-bending abilities like Luffy’s Gear 5, these Mythical Zoan forms easily beat almost any other transformations seen in the One Piece universe. Let us get into the list, then.

10 Marco’s Phoenix Form Made Him Nearly Unkillable

Marco’s Phoenix Transformation is undoubtedly one of the most useful Mythical Zoan forms. Where most Zoan users mainly focus on offense, Marco, on the other hand, excels at self-regeneration and aerial mobility using his blue phoenix flames.

In the Marineford War, Marco fought against some powerful Admirals such as Kizaru and Aokiji, while recovering from otherwise serious injuries. Also, his mythical flames have the power of healing others as well, thus making this form one of the most useful transformations in One Piece.

9 Yamato’s Divine Wolf Form Protected Wano

Yamato’s hybrid wolf transformation combines mythical ice powers with monstrous physical strength. The Okuchi no Makami is worshiped by people for being a protector spirit of Wano, and this fits Yamato’s character perfectly.

What makes this transformation impressive is how effectively it helped Yamato to fight against hybrid Kaido all alone at Onigashima. Her ice-based techniques and durability allowed her to survive direct clashes against one of the strongest creatures alive.

8 Sengoku’s Buddha Form Carried Godlike Power

The former Fleet Admiral possesses one of the oldest revealed Mythical Zoans in the series. The Buddha form of Sengoku transforms him into a huge golden body, which is capable of creating powerful shock waves.

Even during Marineford, Sengoku’s form was powerful enough to briefly overpower Blackbeard and his pirates, even after Blackbeard acquired the Gura Gura no Mi Devil Fruit at that time. Interestingly, the full extent of this Devil Fruit ability still remains unknown, which makes it even more terrifying.

7 Momonosuke’s Dragon Form Copied Kaido’s Power

Despite being labeled a “failure” by Vegapunk, Momonosuke’s artificial dragon transformation is insanely strong. This form possesses almost all of Kaido’s dragon abilities, such as Flame Clouds and Bolo Breath.

However, its most impressive feat came when Momonosuke assisted in preventing the destruction of Onigashima. Though he lacks the fighting prowess of Kaido, the sheer size of this form itself makes it one of the strongest Zoan forms in One Piece.

6 Kaido’s Drum Dragon Form Became a Catastrophe

In Eiichiro Oda’s series, Kaido had one of the most powerful Devil Fruits of all time, which let him transform into an Azure Dragon. However, the Flaming Drum Dragon form elevated Kaido to another level entirely.

With his body covered in flames similar to those of magma, Kaido grew to such an extent that he appeared like a moving island, melting everything around him. This form proved to be one of the most destructive ones ever seen in the One Piece world.

5 The Five Elders’ Yokai Forms Changed the Final Saga

The Egghead Arc finally revealed the monstrous Yokai-like transformations of the Five Elders, and each of their forms immediately felt terrifying even by Mythical Zoan standards.

Their appearance seems highly influenced by Japanese Yokai mythology. With terrifying durability and regeneration, the Elders forced even Gear 5 Luffy and the Straw Hat Pirates to retreat.

4 Loki’s Nidhoggr Form Felt Like a Final Saga Monster

The Elbaf Arc gave one of the biggest Mythical Zoan Devil Fruit transformations ever seen. The massive scale of Loki’s Nidhoggr transformation makes him one of the most powerful final saga characters.

Recently, in Chapters 1180 and 1181 of One Piece, Loki showed the true extent of this power while fighting against Imu. Its lightning abilities and world-ending portrayal make it feel worthy of Yonko-level power.

3 Gear 5 Turned Luffy Into the Sun God Nika

Luffy’s Gear 5 form is one of the most creative transformations in anime history. After his awakening, Luffy gained the power of the legendary Sun God Nika, allowing him to attack with full creativity and freedom.

The transformation bends the environment like rubber, grants cartoon-like physics, and ridiculous adaptability during combat. More importantly, Gear 5 symbolizes freedom itself, making it thematically powerful as well.

2 Imu’s Devil Form Became One Piece‘s Darkest Power

Imu’s demonic transformation totally disrupted the power scaling for the Final Saga. The recent chapters heavily hint that Imu’s abilities allow him to manipulate black flames mentioned as “Omen” in the manga, while using them for offense and reviving others at the same time.

His transformation is terrifying due to its sheer versatility. Instead of relying on brute force, he uses control, regeneration, and immense supernatural power.

1 Joy Boy’s Original Nika Form Was the Strongest

Despite the terrifying nature of Luffy’s Gear 5, Joy Boy, who was possibly the previous wielder of the Nika Fruit, was likely much stronger. For many generations, the World Government tried to cover up the existence of the Fruit, which implies just how much power it had.

Considering all the legends around Joy Boy and his involvement in the Void Century, it could be argued that the original Nika transformation was the peak of Mythical Zoan power in the One Piece universe.
