Kaido vs. Big Mom: Who Would Win in a Fight?

Kaido vs Big Mom: Who Would Win in a Fight?

Why trust us? Check out Fiction Horizon’s Editorial Policy.


Kaidou of the Beasts is considered to be one of the strongest characters in One Piece. Big Mom is a powerful pirate whose true powers have not been explored yet. In this article, we are going to tell you who would win in a direct clash between Kaido and Big Mom.

Both Kaidou and Big Mome are an equal threat to the pirate world and their powers are roughly the same; the main difference is the nature of their Devil Fruits. Based on their current reputations and their histories, Kaidou has a slight edge over Big Mom and it is reasonable to expect that he could defeat her in a direct clash.

The rest of this article will further elaborate on the above-given answer, as we are going to compare Big Mom and Kaido in more detail. Through several categories, you are going to see who the stronger of the two is and why our answer is like it is, i.e., why Kaido would, according to our analysis, be able to defeat Big Mom.

Physical powers

Linlin possesses immense physical strength, demonstrated by his ability to climb tall buildings, deliver powerful punches sufficient to destroy a building, and shatter the ground with his feet. She is also able to throw her minions with great force using only one arm. When she is hungry she produces abnormal amounts of saliva which seems to be much more corrosive than a normal person.

She managed to break down the metal door to her castle’s treasure room, which even her daughter Smoothie, a Sweet Commander, couldn’t get through, just by walking into it. Big Mom possesses enormous resistance thanks to her extremely hard skin, compared by Capone Bege to an iron balloon. She is able to destroy cities, sink ships, and withstand cannons and gunfire without being harmed.

It is said that no weapon can pierce his skin. However, she loses her tenacity when she goes into a psychological breakdown, such as when someone dropped the photo of Mother Caramel that she is enjoying.

Oni Kaidou

Due to his muscle mass, Kaido has enormous physical strength. He managed to capsize nine giant prison ships. Kaido is powerful enough that his single scream caused visible damage to the area around him. One of Kaido’s main strengths is his inability to die; indeed, he suffered seven defeats, was captured by the Navy or enemies eighteen times, was tortured over a thousand times and finally, was sentenced to death forty times. However, no execution, whatever it was, worked.

Kaido also jumped 10,000 meters out of the sky onto the ground, creating a massive shockwave strong enough to sink a nearby ship, and only emerged with a headache; suicide has become a hobby for him. Kaido is as powerful as Charlotte Linlin, being able to fight on equal footing during their fight; like Shanks and Edward Newgate, Kaido and Big Mom were able to split the sky in half after just one hit. So far, no one has been able to stand up to Big Mom, which is highly indicative of Kaido’s power.

Now, while we cannot really determine the difference in strength between these two characters, we somehow do assume that Kaidou’s reputation points to him being physically more imposing than Big Mom, but this could prove to be incorrect sometime in the future.

Points: Big Mom 0, Kaido 1

Devil Fruit

Linlin is the wielder of Soru Soru no Mi, a Paramecia-type Devil Fruit that allows her to manipulate the souls of human beings to the user’s wish. She can remove the soul of her victims by catching it in substance form, reduce their lifespan, and absorb it into herself; if she chooses a sufficient number, she kills the victim.

The latter can introduce a soul into an object to make it alive or into an animal to make it human. The user can also split their own soul into fragments that live as incarnations of the fruit eater. They call themselves the Homies and they cannot oppose Big Mom. Her Fruit is similar to the Kage Kage no Mi, however, she cannot put her souls into corpses or a human. She can also create incarnations of her soul who have the task of collecting the souls of the inhabitants.

Kaido ate the Uo Uo no Mi, Model: Seiryu, a Mythical Zoan-type Devil Fruit that allows him to transform into an oriental dragon, in the same way as Momonosuke, the main difference being that Kaido has a gigantic size in dragon form and appears to be in control of his transformations.

He cannot, however, maintain this appearance if he takes too many powerful blows to keep up like the ones Luffy gave him. He is also able to cause lightning by roaring loud enough. Kaido was also shown to be able to lift the entire island of Onigashima and seems capable of moving it all the way to the Flower Capital.

The nature of Big Mom’s and Kaidou’s Devil Fruits is so different that we cannot really give a proper evaluation of the two in comparison. Both are extraordinarily powerful and/or versatile in their own way, and we cannot but divide the points in this category.

Points: Big Mom 1, Kaido 2


Linlin is one of the few characters capable of using all three types of Haki. Linlin is capable of using Kenbunshoku Haki, but its level of use is unknown. Linlin can make use of Busoshoku Haki, showing immense mastery over it. By stiffening his arm, he was able to easily block Luffy’s Gear Fourth Gomu Gomu no Kong Gun, something that Doflamingo, a very proficient Busoshoku Haki user, had no chance to defend against. Like Luffy’s Gear Fourth, Big Mom’s Busoshoku Haki has flame patterns on its ends.

Charlotte Linlin is capable of using Haoshoku Haki, a skill that only one in a million people is capable of using. The first time she was seen using this ability was to knock out a man who questioned her about her relationship with Mother Carmel. Later, after the destruction of Carmel’s portrait, Big Mom unleashed a large wave of Haki accompanied by her thunderous shriek; knocking out numerous guests at her party. Linlin can also use the advanced form of Haoshoku Haki, seen infusing her fist with it to attack Page One.

Kaido is proficient in Observation Haki and Armament Haki. He also masters the Royal Haki, as he showed during his fight against Charlotte Linlin, another user of this Haki.

This is also a category where we cannot determine a clear winner. Both Kaidou and Big Mom are strong Haki users and it is nearly impossible for us to properly determine the stronger one, which is why we have divided the points here as well.

Points: Big Mom 2, Kaido 3


Big Mom can wield the retractable blade of her Napoleon bicorne as a sword in battle. Using it in combination with his monstrous strength allows him to unleash powerful shockwaves that can cause massive destruction.

No one has yet proven able to withstand Napoleon’s powerful strikes, as even Jinbe has been overwhelmed by the blade despite putting up his best defense. Napoleon can also be caught in the flames of Prometheus to increase his attack power. During her altercation with Kaido, she was able to part the sky following the clash suffered between Napoleon and Kaido’s kanabo.

Kaido possesses a Kanabō, which suits his height; in conjunction with his immense strength, he was able to use it to send one of his subordinates out of his lair and onto Luffy.

Both Big Mom and Kaido have extremely powerful weapons and they are experts in their usage, both of them. This is why we have to divide the points in this category as well.

Points: Big Mom 3, Kaido 4

Big Mom vs. Kaido: Who wins?

Ultimately, the points do reflect our own opinion on the matter. Namely, we have theorized that Kaidou is a tad stronger than Big Mom, and the points do reflect that. They are similarly powerful in many ways, but we’re almost certain that Kaidou is actually physically stronger than Big Mom. This may not be by much, but the difference is, according to us, there.


If you observe their other powers, you’ll see that it is practically impossible to tell the difference. Their Haki abilities are on the same level, they are both masters at wielding their weapons, and their Devil Fruits are so different but equally powerful, that we cannot really determine the better one in the category. This is why we had to divide the points in these categories, and why the final score was as close as it was.

But, due to that small difference between the two Emperors, we think that Kaidou would ultimately be able to defeat Big Mom in a direct clash.
