The fruits of the devil that are in the world of One Piece can be primarily divided into three types, they are Paramecia, Zoan and Logia. Of all three, the Logia types are known to be the most overpowered, given that they allow the user to transform into an element or force of nature, fully embodying that power. The Logia types were first introduced with Smoker in Chapter 97 of One Piecewhich came out officially in Shueisha's Weekly Shonen Jump Issue #34 on July 19, 1999. Since then, the story has come a long way, with much stronger Logia being introduced.
However, the climax of the ongoing Elbaf arc, specifically Chapter 1183, which was officially released on May 24, 2026, in Weekly Shonen Jump Issue #26, confirmed that Logia class is easily outclassed by the Mythical Zoans of the One Piece world. In recent chapters, yet another Logia has fallen behind a Mythical Zoan when it comes to elemental manipulation powers, as Risu Risu no Mi, Model: Ratatoskr has been officially confirmed to have greater powers than Hie Hie no Mi.
One Piece Chapter 1183 Shows Risu Risu no Mi, Model: Ratatoskr is superior to Kuzan's Hie Hie no Mi Logia
One Piece Chapter 1183 put a lot of focus on the character Gunko, or Princess Shuri, with her flashback from the Esperia Kingdom being explored. In this chapter, Eiichiro Oda also confirmed to all fans that Gunko was still trapped in the ice of Ragnir, who has the power of Risu Risu no Mi, Model: Ratatoskr, a legendary Mythical Zoan Devil Fruit from the era of the Void Century. This Devil Fruit is incredibly powerful and gives the user the ability to transform into the Ice Squirrel and use ice manipulation abilities.
Hi Brooke! That chick [Gunko] is still frozen! Can't tell if she's alive or not. We can just leave her there, right? — Franky to Brook, One Piece #1183
In the world of One Piece, there is already a powerful ice ability that falls into the Logia class called Hie Hie no Mi. This Devil Fruit allows the user to transform into ice, as well as create and manipulate said ice at will. Eaten by Kuzan, the Hie Hie no Mi allows him to instantly freeze people to the bone in seconds and even remove things like freezing part of an ocean at will. Kuzan's Devil Fruit is certainly one of the most overpowered seen in One Piece, but when it comes to ice manipulation, it doesn't stand a chance against the power of Risu Risu no Mi, Model: Ratatoskr. One Piece Chapter 1183 officially confirms that even an attack from Nerona Imu's ultimate power, Akuma no Mi, is not enough to melt the ice of Ragnir.

Mythical Zoans are the rarest Devil Fruits, and their transformations are the most overpowered in One Piece.
Ragnir's ice attacks far surpass Kuzan in strength
Earlier, Loki claimed One Piece Chapter 1179, which was officially dropped on April 6, 2026, that the ice of Ragnir can only be melted by Ragnir himself. Shortly after, Imu unleashed a powerful Omen-based attack, charged with Conqueror's Haki, at Gunko in an attempt to free her from Ragnir's ice. One Piece Chapter 1183 confirmed that Imu, the strongest character in the entire world right now, failed to free her from this ice.
Luffy: Hello, Loki. That bad guy you froze earlier…is she dead?
Loki: It's a flash freeze. It won't be fatal, just this guy [Ragnir] can melt the ice.

On the other hand, Aokiji's ice can be easily melted. When Aokiji froze Nico Robin and Luffy in the Long Ring Long Land, both were easily thawed with warm water. Even Mera Mera no Mi's fire stands as a perfect contrast to Aokiji's ice, as does magma. On the other hand, the same cannot be said for Ragnir's ice, which is indigestible and can only be undone by Ragnir himself, displaying an outright superiority of freezing powers.

One Piece Chapter 1176 Shows Loki's Ryu Ryu no Mi, Model: Nidhoggr is superior to Goro Goro no Mi
The theme of Mythical Zoans offering elemental manipulation even greater than Logias is not specific to just Kuzan and Ragnir. In fact, Loki and Enel share a similar sort of relationship. Enel has the power of Goro Goro no Mi, a Logia that allows him to transform into lightning and create and manipulate it on a large scale. Loki, on the other hand, has the ability to transform into the mythical dragon Nidhoggr, who also has the ability to manipulate lightning.
In terms of offensive output, Enel's Goro Goro no Mi has absolutely no chance against Nidhoggr Devil Fruit. Temporary blasts from Loki, such as Thorheim, who officially debuted in Chapter 1175 on March 2, 2026, can blow up entire islands, and this is only a fraction of what he can actually accomplish. Enel, at its peak capacity, can produce 200 million volts of Amaru, but that was not even enough to cause fatal damage to the Straw Hats before the time. Loki, on the other hand, can erase islands, which is why his power is officially stated to be capable of destroying the world over several chapters, such as chapter 1130. In terms of lightning power, Loki far surpasses Enel with his Nidhogg ability, showing once again that the Mythical Zoans outshines Logia when it comes to power output.

Kaido's Drum Dragon surpasses the strength of Magu Magu no Mi
Another interesting example of Mythical Zoan abilities surpassing Logias comes from Kaido's ultimate transformation, called the Flaming Drum Dragon. This form of his is descended from Kaido's Uo Uo no Mi, Model: Seiryu, which is a mythical Zoan Fruit that allows him to transform into an Eastern Dragon. In the peak transformation of this Devil Fruit, Kaido becomes a giant flame and magma dragon that can vaporize an entire island just by passing over it.
“Before your fist can even come down I'll make sure to vaporize it.” — Kaido to Luffy, One Piece Chapter #1048
This Devil Fruit power is very similar to Akainu's Magu Magu no Mi, giving him the power to turn into magma, as well as control and produce it at will. While Akainu's magma burns hot, it can be easily stopped, as seen when Jinbe grabbed his fist for a long time in Marineford, and Marco blocked his attack, completely nullifying it in the process, in chapter 575, released on February 22, 2010. On the other hand, Kaido's magma melted just by passing over it, and even passing over it, even hetashima. Luffy's Gear 5 started burning on mere contact.
With Kaido's ability to vaporize islands, it stands at a much higher level than Akainu's, and on top of that, it also offers other benefits such as improved durability, as well as the power to manipulate wind, along with lightning and fire. All things considered, any major Mythical Zoan that has shown elemental manipulation abilities seems to be significantly stronger than their Logia counterparts, and this is a theme that Eiichiro Oda will likely continue with in the Final Saga.
