Zoro vs. Killer: Who Won the Fight? (& Is He Really Stronger?)

Zoro vs Killer: Who Won the Fight (& Is He Really Stronger?)

One Piece is an anime that certainly has its fair share of strong and powerful characters. And while its protagonist, Monkey D. Luffy, has most often been featured in our One Piece-related comparisons, this one is not going to focus on Luffy in any way. Namely, the protagonists of this comparison are going to be Zoro, who is amember of Luffy’s crew, and the powerful Killer, another member of the “Worst Generation”. In this article, we are going to analyze the two, as we are going to pit Zoro against Killer to finally determine who the stronger of the two is.

Despite what Killer said, Zoro is stronger and could and did defeat Killer when they crashed in the Ringo region of Wano Country. And while it cannot be doubted that Killer is a formidable fighter, Zoro is a lot stronger and has more experience due to his various fights and adventures with the Straw Hat Pirates, which is why he is the winner of this fight.

The rest of this article will further elaborate on the above-given answer, as we are going to compare Zoro and Killer 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 Zoro was ultimately able to defeat Killer when they fought.

Physical powers

Zoro is one of the physically strongest characters in the series. He demonstrates the strength of him when he was fighting Daz Bones, he easily lifted a building despite the injuries he had. He is seen training on the Thousand Sunny with ton weight dumbbells. His strength is surely equal to or greater than that of a giant as he was able to parry a direct hit from Oars with his swords.

After the time skip, Zoro greatly increased his strength. Proof of this is that he was able to defeat a Pacifista with a single attack when before the timeskip he and all his companions joined forces to defeat one, he was able to cut a pirate ship with a single cut, he was also capable of defeating and seriously injuring Hody Jones, a Fish-Man with physical strength above the average of his race when he was underwater and with several Energy Steroids consumed.

One of his greatest feats was defeating Pica in his gigantic form without a single scratch, though he had to turn to Orlumbus to gain mobility and momentum. Zoro has also shown to be very agile and fast. An example of this is that in the Whiskey Peak arc he took on a large number of Baroque Works agents, slipping through their ranks so quickly that they didn’t notice him until he spoke.

Killer is a fearsome pirate and combatant. His skills have earned him a bounty of 200,000,000 Berrys, which is very impressive for a rookie, even within the Grand Line. Just like his captain, he was able to resist Silvers Rayleigh’s Haki. Killer is a highly-skilled fighter, facing off against a fellow member of the worst generation, Roronoa Zoro, who recognized his ability, and managed to injure him with the inadvertent help of the monk Gyukimaru.

Killer’s fighting style seems to be based primarily on speed and agility which he uses to overpower his opponent before he can attack, or to dodge attacks. He was able to fight his partner Supernova Urouge, although the latter had not increased his muscle mass.

In all honesty, Killer looks more powerful than Zoro, that much is obvious from just looking at them. But looks can be deceiving, as Zoro is enormously strong despite not looking it and he is stronger than Killer, which is why he gets this point.

Points: Zoro 1, Killer 0

Devil Fruit

Roronoa Zoro is a very powerful character. He is known as one of the most powerful characters in the series and one of the series’ best swordsmen; he is, by all means, probably going to surpass even Mihawk in the future. Now, Zoro’s powers and feats definitely merit a conclusion that he has consumed a Devil Fruit, but is that really true? It’s not – namely, Roronoa Zoro has never eaten a Devil Fruit.

This makes Zoro one of a very small number of characters (the most notable other one being Shanks and Gol D. Roger) who are extremely powerful, but have not actually consumed a Devil Fruit; most of the other powerful characters have to thank their Devil Fruits for their individual reputations.

Killer consumed a SMILE, which ended up being defective. Because of this, the only thing the fruit has done to him is take away his ability to swim and to be able to express emotions other than laughter. SMILEs are artificial zoan-type Devil Fruits made from SAD.

They were produced by Donquixote Doflamingo and Caesar Clown and consumed by the Beasts Pirates, who formed a division known as Gifters. SMILEs don’t have proper names like normal Devil Fruits, but are referred to as “SMILE of (name of animal)”.

Well, this one was a bummer for Killer really, as he got the short end of the deal. And while neither of them has any Devil Fruit powers, Zoro gets the point because he can still… umm… well… swim and do something other than smile.

Zoro is one of the few people to possess all 3 forms of Haki. Zoro possesses the Royal Haki, the rarest Haki, whose users are said to possess the qualities of a King. He is first mentioned to hold this power by Kaido after Zoro’s nine-sword attack. During his fight against King, he uses the Royal Haki to coat his sabers, a very advanced form, and at the same time members of the Hundred Beasts Crew are seen fainting around.

He didn’t use the Haki offensively against Monet but still managed to beat her as she thought he was going to use the Haki and therefore she was going to die. The fear that Monet felt at that moment completely destabilized her. He has learned to imbue his sabers with Haki to make them more effective against Haki or Devil Fruit users.

He also used the Armament Haki on Pica to slice him which means his Haki is more advanced than Pica’s. Using the Haki also allows him to counter Devil Fruit powers, as he did to temporarily stop the Birdcage.

He first uses the Observation in his fight against Nuru, a Fishman capable of blinding his opponents thanks to the lantern on his forehead, even telling him that he only used his eyes to to see and that was why he was weak; he made use of it again to find Caribou in the palace. He also uses it during the Arc Dressrosa, to find where the one who stole his saber is but also to find Pica during his fight against him.

Killer can use both Observation Haki and Armament Haki, but his level of use in both cases is unknown. This was rather expected, as Killer is not a character strong enough to use all three types of Haki. Still, since we don’t know how powerful he is with his known Haki abilities, we cannot properly evaluate his level of power in this category.

Since Zoro is a rare user of all three forms of Haki, there is no doubt that he wins this point. On top of that, we actually have no clue how powerful Killer is with his two known Haki techniques, which is another argument in Zoro’s favor.

Points: Zoro 3, Killer 0


In the beginning of his journey as a pirate, Zoro only mastered the Santoryu, his conventional fighting style; but over time he began to master techniques from other schools, such as Nitoryu, Ittoryu, or even Mutouryu. Currently, Zoro and the rest of the crew have improved their abilities to face the New World.

Zoro is known to be able to cut through a Pacifista the caliber of those found in the Sabaody Archipelago, so it follows that Zoro can relatively easily cut through materials even harder than steel without using any Shishi Sonson-like moves, very probably because he has learned to use busoshoku haki.

Killer carries two scythes in his fists which he calls Punishers, which he can spin through a mechanism on both wrists and can be used as sickles. These weapons can also be used to block other weapons, leaving the enemy open for Killer to kick the enemy’s flank or other exposed areas.

This, combined with the agility he has so far displayed in combat and the notion that he is not afraid to kill, makes him a formidable foe. As Kamazo, Killer wields two massive scythes that are not attached to his body. However, one of them was stolen by Gyukimaru after his match with Zoro.

Killer’s Punishers might be powerful, there’s no denying that, but they cannot match Zoro’s sword, as was shown in their fight. This is a point that Zoro wins as well.

Roranoa Zoro vs. Killer: Who wins?

We could, actually, give you a proper analysis of the things we have written above but that wouldn’t really do the trick when compared with what we have decided to go with. Namely, as Zoro and Killer have, indeed, fought in the manga, we thought that it would be better for us to just recap these fights to confirm what we have said above.

After meeting Kaido, Killer was imprisoned and cared for by Kurozumi Orochi, who fed him a SMILE which turned out to be faulty. His mask was removed, and Killer served as the assassin for Kurozumi Orochi under the alias of “Kamazo”. In the Flower Capital of Wano Kuni, a newsboy cries that the “ghosts” of the northern cemetery have returned and causes a stir.

In 8th Street of the 2nd district, someone was killed and the assassin is none other than Kamazo. Despite the fact that his identity is known, he has still not been captured. He then reappears in Ringo, where he makes his first real appearance. He pursues a Geisha as well as O-Toko, but is confronted by Zoro, who goes to help the Geisha and Toko.

It turns out that he works for the Shogun, and easily stands up to Zoro, to the point where he manages to hurt him when he was distracted by Gyukimaru. Zoro then takes the opportunity to grab his scythe frozen in his shoulder, place it in his mouth, telling himself that it will do the trick, and use it to attack Kamazo with an “Onigiri”, dealing an improvised blow to him with his three blades.

Kamazo fell defeated, after which he was arrested and imprisoned in Udon, for failing Orochi’s mission. He finds his former captain, Kid, there on the way, and the two prisoners are then tortured by Queen. Queen has them tortured by plunging them underwater, and they only come out of the water when Big Mom attacks Queen in Brachiosaurus form and knocks him onto the pelvis, breaking it and allowing them to breathe.

And this is how the fight between Killer and Zoro ended. Zoro is the clear winner here, as was demonstrated in the manga and the anime. It was a quick fight for one of the best swordsmen in the world and Killer simply couldn’t match Zoro’s skills.
