One Piece has been going strong for what feels like forever, even to hardcore fans. The characters have experienced a lot during their worldwide travels and have the scars to prove it. The Straw Pirates have gone through a lot during their run, but they still have plenty of adventures to go on.
To prepare for those adventures and any battles that might happen, weapons are needed. The Straw Pirates have a variety of weapons at their disposal, but there are others out there with deadlier ones. Some of these weapons may look harmless or look like ordinary weapons, but caution should be heeded when near them or their wielders.
Updated on December 4, 2021, by Sarah Prado: There are plenty of weapons in the world of One Piece. The weapons are only as deadly as their wielders. Their wielders don’t have to be strongest, but wits and strategic use have proven to be just as deadly. If any of these weapons appear, fans know that an entertaining battle is sure to ensue.
With the skills that these wielders have, the weapons are able to be used at their max potential. Whether it’s a harmless-looking shell, a rod, or even body parts, there’s a lot of options. Even the Devil Fruit can be seen as weapons, depending on the wielder and what they do with those powers.
12 Dials
They may look like ordinary shellfish, but these shells can pack some serious firepower in One Piece. Dials can look like an ordinary average shell or be as large as a human. The Dials each have different functions. Some can function as recorders, store aromas, or be used for everyday life in some way. Then, there are the ones that can store energy and be used in combat. Dials are already powerful on their own, but in the right (or wrong) person's hands, they can be deadly on the battlefield.
Usopp demonstrated strategic use with the Impact Dial in his fight against Luffy and also used a Flash Dial to temporarily blind him. The Reject Dial (a stronger version of the Impact Dial) can also hurt the user and is said to even destroy the bodies of the inexperienced. It's not known exactly how much energy it can store, but it's capable of storing a lot of power. Usopp even used them to improve Nami's weapon and changed it into the Perfect Clima-Tact.
11 The Pacifista
Human weapons created by Dr. Vegapunk and modeled after Warlord Bartholomew Kuma, these cyborgs are made of metal stronger than steel. Even Zoro's sword can't cut through them as shown in his fight against a partially-converted Kuma. The Pacifista have an electronic scope that allows them to identify wanted pirates. Their main weapon for combat is their laser beams that come from their mouths and hands.
The lasers are lethal and can have a large amount of piercing power and cause massive explosions. They can jump real high and run faster than most people. They can also withstand an enormous amount of damage. The Straw Hats have had trouble taking down one of these cyborgs in One Piece.
10 Clima-Tact
She might be part of the Weakling Trio, but Nami is far from being the weakest member of the Straw Hat Pirates in One Piece. Originally created by Usopp, this weapon allows Nami to manipulate the weather around her. From using it for everyday tasks like showers to summoning thunder clouds that can do serious damage. It can also create a mirage to make Nami invisible. She can keep this up for a while until she swings the Clima-Tact again.
Nami is able to control the weather around her and take out groups of enemies. Thanks to her time on Weatheria, Nami is able to masterfully wield the Clima-Tact using her knowledge of meteorology and weather systems. She might not be strong like Sanji or Zoro, but Nami’s skill with this weapon makes her a very useful ally.
9 Kaido's Kanabo
Wielded by the "Strongest Creature" of the world, Kaido of the Beasts' weapon is made of a dark metal that has studded spikes covering it. This oversized club is capable of sending anyone hit by it flying great distances.
Kaido was able to damage Luffy, who is usually able to take blunt force hits with little to no problems, and greatly damage him. Compared to most weapons, Kaido's Kanabo might not look like anything special, but it's Kaido that opponents should be worried about. With his immense strength, this kanabo can do serious damage to anyone or anything unfortunate enough to be in his way.
8 Devil Fruit
The fruit that is responsible for giving a good chunk of One Piece characters their powers. These fruits can give users powers that range from controlling the elements to possibly being able to destroy the world.
Not only are these fruits able to grant power, but those abilities are also only effective if the user can use them properly. Many Devil Fruit users have been able to use their abilities to their max potential and continue to push those boundaries. Some scientists have even found a way to create artificial Devil Fruits though they are inferior to the real thing.
7 Sanji's Legs
While not exactly a normal weapon, Sanji has made his legs his weapon of choice. They may not look intimidating at first glance, but they pack some serious power. To keep his best tools (his hands) protected, Sanji has trained in the martial art known as the Black Leg Style. Thanks to being with the Straw Pirates and gaining experience, Sanji has come up with his own techniques. He can easily destroy boulders, metal weapons, and giant monsters.
Thanks to his training and combat experience, Sanji gained a new ability: Diable Jambe. With this, he can raise the heat in his lower legs, making them glow and boost his power. The heat is very high and can easily set a person on fire.
6 Murakumogiri
The weapon that Edward Newgate/Whitebeard used for over 30 years. It’s a naginata weapon that’s part of the 12 Supreme Grade swords, the best weapons in the world. Combine this with Whitebeard’s skill and immense power, this is one of the strongest weapons in the One Piece series. He was able to clash against other powerful swords like Enma and the Ame no Habakiri, two swords from the 21 Great Grade swords.
It’s a very durable weapon because Whitebeard would often use it in conjunction with his Devil Fruit powers, the Quake-Quake Fruit, and Busoshoku Haki. Considering that Whitebeard has had this weapon for decades, it shows no signs of wear and tear. After he dies, the weapon is placed on his grave and still looks immaculate.
5 Yoru
One of the strongest swords in the world of One Piece that's wielded by the "Strongest Swordsman in the World," Dracule Mihawk. It is one of the highest quality swords ever made. Combined with Mihawk's swordsmanship, Yoru can cut through large structures from a galleon to a mountain of ice.
He can send powerful flying sword slashes through the air to great distances. With someone like Mihawk wielding it, Yoru has been able to withstand a lot of power being channeled through it.
4 Enma
One of the best swords ever made and one of the 21 Great Swords. This sword requires the wielded to not just be physically strong, but spiritually strong. This weapon can drain an ordinary swordsman’s Haki and turn them into a dried-up husk if they're not strong enough. Very few have been able to wield Enma properly and those who master it, are granted immense power.
One swordsman, Kozuki Oden, is said to have bisected a Mountain God wielding it. He also used it against Kaido, a pirate known for his near indestructibility. Roronoa Zoro is the new wielder and is the second swordsman to master Enma.
3 Shusui
The Shusui is one of the 21 Great Swords that's the prized treasure of the country of Wano. It is the signature weapon of the legendary samurai, Shimotsuki Ryuma. Shusui is designed to amplify the wielder's power to terrifying heights.
It is capable of dealing heavy blows and is extremely durable against strong attacks. Zoro was able to deflect Oars' punch and defend against Neptune's Trident. He was also able to cut a large galleon ship in half, beheaded a huge dragon in one slash, and take out a mountain-sized golem with strong slash attacks.
2 Tremor-Tremor Fruit/Quake-Quake Fruit
This fruit is one of the deadliest Devil Fruits to ever exist. It was eaten by Edward Newgate, AKA Whitebeard, and is considered the deadliest of the Paramecia class. This fruit grants the person the ability to create vibrations/quakes and is said to be able to destroy the world. It is possible to wipe out islands with the power of this fruit, but it does take a lot of energy to do so. If not properly controlled, the wielder of this power can take out enemies and allies.
Whitebeard was able to control this power and focus it on his hands or feet. He was able to take out Vice-Admiral Ronse in one blow by grabbing his head and focusing the vibrations in his hand.
1 Dark-Dark Fruit
A Devil Fruit that is said to be a very unique Logia-type, this fruit allows the user to be able to control darkness at will along with a unique property of gravity. It devours and crushes everything in its path. It can absorb physical matter and any attack. The user can even pull their opponents to them no matter what kind of state they're in. It's even similar to a black hole and can suck things into a vortex.
If this fruit doesn't sound deadly enough, the most terrifying power of this fruit is that the user can nullify other Devil Fruit users' powers. All the user has to do is be in physical contact with them and they won't be able to use their abilities. What makes this particular fruit even more terrifying is the current user: Marshall D. Teach AKA Blackbeard.
