One Piece is an anime that certainly has its share of strong and powerful characters. And while its protagonist, Monkey D. Luffy, is certainly one of them, some characters might be even more powerful than the manga's cheerful and quirky protagonist. In this article, we'll be comparing two of those characters, pitting Kaido against Momonosuke, a character who—in some ways—is strikingly similar to Kaido, to see who is the stronger of the two. You'll also find out if Kaido and Momonosuke have the same Devil Fruit.

Kaido is the more powerful fighter of the two and could defeat Momonosuke in a head-to-head confrontation. Kaido is stronger. He knows more Haki techniques and has more experience with his Devil Fruit. Even the fact that Momonosuke is a better swordsman than Kaido wouldn't help him in this battle.

The rest of this article will expand on the answer given above by comparing Momonosuke and Kaido in more detail. Across several categories, you'll see who is the stronger of the two and why our answer is the way it is—that is, why Kaido would, according to our analysis, be able to ultimately defeat Momonosuke.

Physical powers

Momonosuke, the head of the Kozuki family, is the leader of all its members, including Inuarashi and Nekomamushi, the leaders of the Mink Tribe. He is also one of the leaders of the Ninja-Pirate-Mink-Samurai Alliance, making him incredibly influential within this organization. Momonosuke controls the alliance's Wano warriors as their leader. Furthermore, the majority of Udon's inmates joined the alliance thanks to his presence.

As a young man, he uses this power sparingly and leaves most of the decision-making to his devoted servant Kin'emon. Momonosuke managed to withstand a severe beating from Kanjuro, which surprised the samurai, who attributed this to Momonosuke being Oden's son, despite not displaying the superhuman power his father possessed as a child. This was further demonstrated when Momonosuke reached adulthood; he seems to have inherited his father's endurance and tenacity, as he felt absolutely nothing after being beaten by Nami and Hiyori.

Thanks to his muscle mass, Kaido possesses enormous physical strength. He has managed to capsize nine giant prison ships. Kaido is powerful enough that his scream alone causes visible damage to the area around him. One of Kaido's greatest strengths is his inability to die; in fact, he suffered seven defeats, was captured eighteen times by the navy or enemies, was tortured over a thousand times, and was ultimately sentenced to death forty times. However, no execution, whatsoever, has worked.

Additionally, Kaido jumped 10,000 meters above the ground, sending out a powerful shockwave that could have sunk a nearby ship, but he only suffered from a headache; suicide became a hobby for him. Like Shanks and Edward Newgate, Kaido and Big Mom were able to split the sky in two with a single blow, proving they were as powerful as Charlotte Linlin. Big Mom has yet to be defeated, which is a strong indication of Kaido's strength.

There's no doubt that Kaido is physically stronger than Momonosuke. Kaido's physical powers are truly impressive, and there are only a handful of characters who can match the Yonko in this category.

Devil Fruit

Momonosuke ate an artificial Devil Fruit created by Vegapunk, which Vegapunk deemed a failure. It is a Zoan-type fruit that transforms him into a serpentine dragon and appears to give him the power of flight by creating clouds to which he can cling. Having eaten this fruit very recently, Momonosuke was not in full control of its power and was unaware that it was possible to revert to human form until Luffy told him. He would later revert to his human form when Kin'emon regained consciousness.

Kaido ate the Uo Uo no Mi, Model: Seiryu, a Zoan-type Mythical Devil Fruit that allows him to transform into an oriental dragon, similar to Momonosuke, the main difference being that Kaido is gigantic in size in dragon form and seems to control his transformations.

However, he will be unable to maintain this appearance if he is hit by too many powerful strikes, such as those launched by Luffy. He can also growl loud enough to unleash lightning. The entire island of Onigashima has been seen to be able to be lifted by Kaido, and he appears to be able to move it all the way to the Flower Capital.

Although both of their Devil Fruits are fundamentally the same, Kaido still has much better control over his Devil Fruit. Since he possesses the original version, while Momonosuke deserves credit here, we have to give this point to Kaido as well.

Do Momonosuke and Kaido have the same Devil Fruit?

This is a small addendum to our usual structure, but it's a relevant question for the series. Because of their similarities, fans have been wondering if Momonosuke and Kaido have the same Devil Fruit, and the answer is no. And yes. No, because it's impossible for two people to share the same Devil Fruit powers, as no matter how many people eat a single Devil Fruit, its powers will only manifest in one. But the Devil Fruit Momonosuke consumed was an artificial Uo Uo no Mi, Model: Seiryu created by Vegapunk, i.e., the artificial version of Kaido's original Devil Fruit, so in a way, their powers come from the same fruit, only Kaido's are real, while Momonosuke's are artificial.

RIGHT

Kenbunshoku Haki is, as far as we know, the only Haki Momonosuke can use. He demonstrated this talent in Onigashima during the Wano Country arc when, despite being very far away from Luffy, he could still tell how the battle against Kaido was going. As far as we know, Momonosuke cannot use any other Haki techniques.

Kaidou is one of a very small number of people who can use Haoshoku Haki. Upon colliding with Charlotte Linlin using her Kanabō, they both generated a typical lightning discharge. Kaidou can use the advanced variant of Haoshoku Haki, imbuing his Kanabō with his will, which violently expels black lightning from its tip and causes it to expand towards his enemies.

Kaido is capable of using all three types of Haki, while Momonosuke is known for only using one of the three types of Haki. Therefore, according to tradition, this point should be given to Kaido, as he knows more types of Haki than Momonosuke.

Weapons

Momonosuke learned the basics of swordsmanship from his father at a young age. Although Momonosuke has been seen in possession of swords, he has not been seen wielding them in actual combat. Therefore, his skill level in handling them is unknown. After returning to Wano, he is seen practicing his swordsmanship on various occasions, but he still does not consider himself worthy enough to wield Ame no Habakiri.

Later, during the three days leading up to the attack on Onigashima, Momonosuke is seen training and receiving guidance from Zoro. Momonosuke, who was restrained by Kanjuro, was able to extricate himself from the ropes using a knife he discovered on the ground. Although the samurai quickly overcame him, Momonosuke was able to use his knife to slice Kanjuro's palm during the fight.

Kaidou uses his Hassaikai, a giant metal Kanabō filled with spikes and adapted to his size, against his opponents. In addition to its immense physical strength, he can use it to crush his opponents and send them flying great distances. He was able to knock Luffy unconscious with a single blow, breaking the enormous defensive power of his Busoshoku Haki enhanced with his Gear Fourth form. With it, he could also block Charlotte Linlin's attack with Napoleon, an extremely powerful sword. Kaidou killed Kozuki Oden using a double-barreled pistol, but it is unknown what happened to this weapon today and if he still has it in his possession.

Kaido may not be the best swordsman in One Piece, but he's certainly skilled enough to be among the best. On the other hand, Momonosuke is one of the best swordsmen in the series, and he surpasses Kaido in this category, which is why he wins this duel.

Momonosuke vs. Kaido: Who Would Win?

And now, let's move on to the most important and interesting section of our article: the analysis. Here, we'll take what we've discovered about these two characters and analyze how all these facts would help them (or not) in their fight against each other. Let's continue.

The points are pretty clear in this confrontation, and they reflect the state of affairs as you'd expect. Kaido is far stronger and more imposing than Momonosuke. While the samurai is definitely a better swordsman, he fails in every other category, including the Devil Fruit, as Kaido possesses the original and is far more experienced than Momonosuke.
