Koby was the first friend Luffy made when he embarked on his pirate journey. He started off as a scared and scrawny boy, but thanks to his dedication and Vice-Admiral Garp’s training, he has become one of the strongest Marines in One Piece.
The Egghead Arc revealed that Koby can use an advanced form of Armament Haki, and his strongest attack, Honesty Impact, has enough power to level an entire mountain. As a result, Koby can now defeat several of One Piece‘s strongest pirates.
Most of the pirates that Koby can destroy are captains or high-ranking officers. His Honesty Impact attack can take out some of Luffy’s toughest opponents with one hit, and his standard Haki infused punches can beat certain pirates as well. Koby can now beat certain Yonko commanders, and he can take out a specific Yonko very easily.
10. Pica’s Devil Fruit Would Be Obliterated By Koby’s Honesty Impact Attack
A Top-Ranking Pirate Officer Who Can Harden His Entire Body And Transform Into A Massive Stone Golem
Affiliation: The Donquixote Pirates
Bounty: 99,000,000
Japanese Voice Actor: Yuji Mitsuya
English Voice Actor: Ry McKeand
Pica is one of the top three officers of the Donquixote Pirates and one of the few individuals capable of hardening his entire body with Armament Haki. He was able to withstand most of Zoro’s Haki-infused attacks during the Dressrosa Arc, but they were eventually able to defeat him. Koby’s Armament Haki is now on par with Zoro’s, meaning he can injure Pica’s reinforced body.
Pica ate the Stone-Stone Fruit, a Paramecia-type Devil Fruit which allows him to merge with and manipulate stone. As a result, he can turn himself into a colossal stone golem. This technique is similar to Avalo Pizarro’s Devil Fruit, but it is somewhat weaker because of its limited scale. Koby annihilated Pizarro’s island arm with his Honesty Impact, meaning Pica’s golem would likely be reduced to rubble in a similar fashion.
9. Arlong’s Fish-Man Psysiology Cannot Withstand Koby’s Haki Infused Punches
A Ruthless And Dangerous Pirate Who Sees Humans As Worthless Vermin
Affiliation: The Arlong Pirates
Bounty: 20,000,000
Japanese Voice Actor: Jurota Kosugi
English Voice Actor: Chris Rager
Arlong was the main villain of the Arlong Park Arc, and at one point in time, he was the most dangerous pirate in East Blue. He had a deep hatred towards humans and viewed them as inferior beings. Like all fish-men, Arlong’s physical strength is naturally ten times greater than an average human, but even among fish-men, his strength is considered exceptional. His body is also quite durable, as he was able to survive an encounter with then Vice-Admiral Kizaru.
Arlong does not have a Devil Fruit, and he does not appear to have any type of Haki, but he was able to take pre-timeskip Luffy to the absolute limit because he is a good melee fighter. Unfortunately, Arlong would not stand a chance against a strong Armament Haki user like Koby. His body might be durable, but Koby’s Haki infused punches would deal serious internal damage to Arlong. Given his training, Koby should be able to defeat Arlong with half a dozen Haki strikes.
8. Hody Jones Would Be Pulverized By Koby Even If He Uses Energy Steroids To Strengthen His Body
A Fearsome Fish-Man Who Gathered An Army Of 100,000 To His Cause
Affiliation: The New Fish-Man Pirates
Bounty: None
Japanese Voice Actor: Joji Nakata
English Voice Actor: Larry Brantley
Hody Jones is the founder and captain of the New Fish-Man Pirates, and his main goal was to overthrow King Neptune and create a new world where all of humanity is enslaved. Hody is a great white shark fish-man who gained a lot of combat experience while serving in Neptune’s army. He wields a trident with deadly skill, and his strength is considered monstrous even by fish-man standards.
Hody is considered a Fish-Man Karate novice, but he can still hurl water droplets like bullets. He does not have a Devil Fruit or Haki, but he was able to enhance his strength and durability with Energy Steroids. While in this enhanced state, Hody was strong enough to really hurt post-timeskip Luffy. If Koby landed a direct hit with his Honesty Impact, most of Hody’s enhanced muscles would be flattened and many of his bones would likely shatter at once. Hody became a frail old man due to the side effects of the Energy Steroids, which means Koby can now take him out with a single punch to the head.
7. Caribou’s Logia Powers Would Be Nullified By Koby’s Advanced Armament Haki
A Super Rookie Who Has Made A Name For Himself By Killing Marines
Affiliation: The Caribou Pirates
Bounty: 210,000,000
Japanese Voice Actor: Masaki Terasoma
English Voice Actor: Andrew Kasten
Caribou is the co-captain of the Caribou Pirates, and is considered a super rookie because he obtained a bounty of over 100 million Berries in a short period of time. He earned his bounty by killing Marines without hesitation, and he wishes to become part of Blackbeard’s crew. Caribou does not seem to possess any type of Haki, but he was fortunate enough to find a Logia-type Devil Fruit.
The Swamp-Swamp Fruit gives Caribou the ability to create, control, and transform into mud at will. He typically restrains and immobilizes his targets by creating bottomless swamps, and he can store an infinite amount of things in his body. Like most Logia users, Caribou’s body is intangible, meaning most non-Haki attacks safely phase through his body.
Unfortunately, Koby’s Armament Haki directly counters Caribou’s intangibility, which means he would feel the full force of Koby’s infused punches. A dozen of these punches should knock Caribou out if they all connect. Koby should also be able to break free of Caribou’s restraints with his Haki.
6. Chopper’s Monster Point Would Not Withstand Koby’s Honesty Impact
A Gifted Doctor Who Is Capable Of Assuming Multiple Forms Thanks To His Devil Fruit
Affiliation: The Straw Hat Pirates
Bounty: 1,000
Japanese Voice Actor: Ikue Otan
English Voice Actor: Brina Palencia
Chopper is the doctor of the Straw Hat Pirates, and his comically low bounty does not represent his strength. He consumed the Human-Human Fruit, a Zoan-type Devil Fruit that transformed him into a reindeer-human hybrid, granting him human-level intelligence and the ability to speak. Chopper has access to several combat forms, with Monster Point being the strongest.
While in this form, Chopper grows very large and his physical strength increases significantly. He was able to defeat a member of CP9 with Monster Point, and he briefly clashed with Queen, an Ancient Zoan user and Yonko Commander, during the Onigashima Raid in Wano. Monster Point may be strong, but it cannot withstand a direct hit from Koby’s Honesty Impact. Chopper cannot use Armament Haki, so he would not be able to protect himself from the impact.
5. Avalo Pizarro’s Devil Fruit Has Already Been Countered By Koby’s Newfound Power
An Infamous Impel Down Prisoner Who Can Merge With Islands And Manipulate Its Environment
Affiliation: The Blackbeard Pirates
Bounty: Unknown
Japanese Voice Actor: Masaya Takatsuka
English Voice Actor: Greg Silva
Avalo Pizarro was held in the lowest level of Impel Down, which means he was deemed to be extremely dangerous. He is now one of Blackbeard’s Ten Titanic Captains and leads the crew’s fourth ship. He has not demonstrated any Haki, but it is safe to assume he possesses it given his status. Avalo has eaten the Isle-Isle Fruit, which gives him the ability to merge with an island’s environment and manipulate it.
Avalo revealed the scope of this power when Vice-Admiral Garp rescued Koby from Pirate Island. He turned a large portion of the island into a colossal arm and attempted to destroy a Marine battleship carrying civilians. Koby obliterated this arm with his Honesty Impact. If Koby fights Avalo on an uninhabited island, he can keep hitting Avalo with Honesty Impact shots until his main body loses consciousness.
4. Gecko Moria’s Strongest Technique Would Be Totaled By Koby’s Honesty Impact
A Former Warlord Of The Sea Who Has The Power To MaNipulate Shadows
Affiliation: Thriller Bark Pirates
Bounty: 320,000,000
Japanese Voice Actor: Katsuhisa Hoki
English Voice Actor: Chris Guerrero
Gecko Moria is the captain of the Thriller Bark Pirates and the former captain of the Gecko Pirates. He was part of the Seven Warlords of the Sea – a group of powerful pirates who worked with the World Government. Moria heavily injured Luffy when they fought and clashed with Kaido in the past. He has not exhibited any Haki, but he can manifest and control shadows because of the Shadow-Shadow Fruit. This can create a zombie army by stealing shadows from others and placing them inside corpses.
Moria can become larger and stronger by inserting stolen shadows into his body, but this would simply make him a bigger target for Koby. During the Summit War, Moria was knocked out by one of Jinbe’s punches. Koby’s Honesty Impact is much stronger than Jinbe’s punch, and its destructive force would ripple through Moria’s entire body after a direct hit. Moria can endure regular Haki punches, but Honesty Impact is at least ten times more powerful.
3. Page One’s Ancient Zoan Body Cannot Compete With The Power Of Koby’s Strongest Punch
A Top Yonko Officer Who Can Transform Into A Carnivorous Dinosaur
Affiliation: The Beast Pirates
Bounty: 290,000,000
Japanese Voice Actor: Yutaka Aoyama
English Voice Actor: Tom Laflin
Page One was part of Kaido’s Flying Six, making him one of the Beast Pirates’ strongest members. He can use Observation Haki and Armament Haki, and he possesses the Dragon-Dragon Fruit, Model: Spinosaurus. This Ancient Zoan-type Devil Fruit allows Page One to transform into a Spinosaurus, and he can assume an empowered hybrid form. Given the carnivorous nature of a Spinosaurus, this Devil Fruit is well-suited for combat.
Page One was able to get back up after getting kicked multiple times by Sanji, but this happened before Sanji awakened his superhuman strength. That said, Page One’s body is still incredibly durable because he is an Ancient Zoan user. That said, Koby’s Haki punches can do serious damage to Page One’s body. If Koby lands his strongest punch on Page One’s neck, he should be able to knock him out instantly. Big Mom took him down in the same way with a punch that was infused with Conqueror’s Haki.
2. Charlotte Cracker’s Biscuit Defenses Would Crumble If They Take A Direct Hit From Koby’s Attacks
A Yonko Commander Who Was Able To Injure Luffy’s Gear 4 Transformation With His Own Haki
Affiliation: The Big Mom Pirates
Bounty: 860,000,000
Japanese Voice Actor: Takuya Kirimoto
English Voice Actor: David Matranga
Charlotte Cracker is one of Big Mom’s three Sweet Commanders, and he defeated Urouge, a member of the Worst Generation, very easily. He ate the Bis-Bis Fruit, a Paramecia which allows him to create and manipulate biscuits. He typically creates biscuit armor which is strong enough to withstand some of Luffy’s Gear 4 attacks. Cracker’s Armament Haki is especially potent, as his imbued sword is strong enough to cut through Luffy’s Gear 4 arm which is covered in Armament Haki.
Koby’s Honesty Impact has the power to annihilate a colossal arm made from an island in a single blow, so it is hard to imagine Cracker’s biscuit armor withstanding a direct hit from the same attack. In a direct clash, Koby’s Haki infused fist should be able to break Cracker’s signature sword. It is worth noting that Cracker’s main body is far less durable than his biscuit armor, so Koby’s strongest attack should knock him out instantly.
1. Buggy Can Be Defeated By Any Of Koby’s Haki Infused Punches
A Cowardly And Weak Yonko Who Can Split His Body Into Pieces
Affiliation: The Buggy Pirates, Cross Guild
Bounty: 3,189,000,000
Japanese Voice Actor: Shigeru Chiba
English Voice Actor: Mike McFarland
Buggy is a beloved villain who has been part of One Piece‘s story since the beginning. He was once an apprentice on Gol D. Roger’s ship and became a Warlord after the Summit War. A clerical error caused the world to believe he was the leader of Cross Guild, and he was named a Yonko as a result. Buggy cannot use Haki, but he can split his body into pieces because of the Chop-Chop Fruit. This Paramecia makes Buggy immune to slashing attacks, but punches still hurt him.
The world may think Buggy is powerful, but he is actually very weak, and at times, quite cowardly. Given his strength and durability, Buggy would be killed if Koby hits him in the head with his strongest punch. Fortunately, Koby does not need to use that much power. In reality, Koby can easily pummel Buggy with ordinary Haki infused punches.
