One Piece

A word filled with pirates and marines looking for a treasure known as the “One Piece”

body of saltwater broadly divided into quadrants: the East Blue, the West Blue, the North Blue, and the South Blue.[2][3] These divisions are formed by two natural barriers that bisect the world at roughly perpendicular angles:

The Grand Line, a relatively narrow strip of ocean infamous for its unnatural, rapidly-shifting climates and monstrous wildlife—as well as being enclosed by the completely wind- and current-free Calm Belt regions.

The Red Line, a huge (and mostly barren) landmass that functions as the world’s only true continent.

All parts of the Blue Sea—Grand Line and Calm Belts included—contain numerous islands supporting many different degrees of life. Travel between these islands is relatively simple in the four Blues, but significantly more complex in the Grand Line, where (in addition to the aforementioned hazards) many islands produce unique magnetic fields that render the magnets of ordinary compasses useless, necessitating special “Log Pose” compasses.

North and South poles, both reputedly very cold, have also been stated to exist.[4][5] It is unknown where they are located, or whether they contain the actual magnetic poles that control compasses outside the Grand Line.

Because of this abdundance of water, the moon’s ancient inhabitants referred to planet as the “Blue Star” (青色の星, Aoiro no Hoshi?).[6]

Grand Line

Main article: Grand Line

Said to be a giant sea route which circumnavigates the world, it is the one sea where normal compasses fail. It is the destination of every pirate and the path that leads to unimaginable adventures. Most of the story is based in the Grand Line. The reason this sea is sought by a large number of pirates is that the greatest treasure “One Piece”, left behind by the legendary pirate Gol D. Roger, is said to be on the final island of Grand Line (“Laugh Tale”). The Grand Line is divided into two halves by the red line. The first half, known as “Paradise” to the residents of the second half of the Grand Line, is wildly unpredictable and dangerous, but pales in comparison to the second half. The next half, which is said to be much more difficult and dangerous than the first half, is the “New World”. The Four Emperors unofficially rule the New World.

Devil Fruits are a major plot device in One Piece. They are supernatural fruits that are scattered throughout the world, though they are mostly seen within the Grand Line, and can grant special powers to anyone who eats them, ranging from the simplest abilities to highly destructive ones, and even the incredibly bizarre. As a price for consuming a Devil Fruit, the individual permanently becomes weak to seawater, essentially losing the ability to swim at all. There is no known way to remove the power or weaknesses, but once a user dies, the power will be reborn into another fruit waiting to be consumed by someone else. In addition, an individual can only acquire the power of a single Devil Fruit and survive, with only one notable exception for unspecified reasons. Their exact origin is a mystery, but they have existed for at least 800 years.

All Devil Fruits are broadly grouped into three separate types based on what kind of powers they grant: Paramecia, which grant a wide variety of strange superhuman abilities, which, in general, do not fit into either of the other two types; Zoan, which allows a user to transform into a specific animal as well as an animal hybrid, including prehistoric and even mythological ones; and Logia, which grants a user the power to create, control, and transform their body into a natural element, and is widely considered the rarest and most powerful class of Devil Fruit. Each fruit is given a name based on what power it possesses, and can be identified by its appearance. Some fruits grant powers that are similar to others (some are even considered superior to another), but each and every one is unique to itself; in other words, no natural Devil Fruit has exactly the same power as another. Some fruits, however, grant abilities that are considered to be very unique to others of the same type. One fruit, in particular, has the honor of having two names while also fitting into two types.

Devil Fruits are known to have empowered many of the world’s most significant individuals, especially those among the Three Great Powers. This, along with their general rarity, causes them to be highly sought-after; single specimens may be valued at hundreds of millions in Belly, and extensive efforts have been made to mass-produce artificial versions for warfare. However, one does not need a Devil Fruit to become powerful, as there have been people who have garnered incredible fame and influence without ever having to eat one, such as the late Pirate King, Gol D. Roger.

Devil Fruits come in all different shapes and colors, though all the Devil Fruits seen so far have possessed swirl marks or patterns.[2] The only known exceptions are artificial Devil Fruits, which have ring patterns on them.[3] The oldest introduced Devil Fruits are the Toki Toki no Mi and Hito Hito no Mi, Model: Nika, which have existed in the world for at least eight centuries.[4][5]

It is currently unknown what Devil Fruits are exactly, where they came from, or exactly how they work. Dr. Vegapunk theorizes that Devil Fruits are a manifestation of the possibility for human evolution, with all the different powers representing the many branches for humanity’s future, brought into existence by human hope and desire: thoughts along the lines of “if only I could do this” or “if only I could be like that”. Vegapunk claims that those with powers exist in different dimensions dreamed up by others before them. However, according to Vegapunk, those who exist in this unnatural state are loathed by the sea, which he describes as the mother of nature, and thus become unable to swim as punishment.[6] It is unknown how much of Vegapunk’s theory is true, but it is a fact that consuming Devil Fruits alters a person’s Lineage Factor, which grants them supernatural powers.

Haki is a mysterious power that allows individuals to harness their own spiritual energy for various superhuman feats. As this energy manifests from willpower, it is theoretically open to all of the world’s living creatures; the vast majority, however, are either ignorant or unable to achieve mastery. Haki users are common in the New World, rare in Paradise, and basically non-existent in the Four Blues.

Current understandings of Haki define three distinct types, each tied to a different ability: sensing others’ spiritual energy to anticipate their movements, producing a protective coating of energy from one’s own body, and—for a certain group of “chosen ones”—overwhelming the willpower of others.[2][3]

Haki and its users have underpinned many significant events throughout the series—notably, Shanks used it to drive off the Lord of the Coast and save a young Monkey D. Luffy’s life.[1] The term “Haki” was first coined and used much later when Blackbeard was commenting on Luffy’s bounty in Jaya,[4] and was hinted at during Shanks’ visit with Whitebeard.[5] The underlying concepts of Haki were introduced during the Sabaody Archipelago and Amazon Lily Arcs.[6][7] The concept was clearly explained later on by Rayleigh to Luffy at the start of the latter’s training on Rusukaina Island.

Haki is dormant in every living person, but most people around the world never even learn about the existence of Haki, let alone how to utilize it. The people who do usually awaken it through proper instruction and intense training. Haki is apparently quite difficult to master, as Rayleigh stated that two years was not enough time to learn the basics,[8] though several characters managed to master it within the span of the two year timeskip, including Luffy, Zoro, Sanji, Tashigi, Smoker, Koby, and Bellamy. In very rare instances, a person can awaken their Haki on their own due to an experience of extreme stress or shock, such was the case with Koby during the Summit War of Marineford,[9] and Ace during his battle against Vice Admiral Draw. Some people (such as Aisa and Otohime) are actually born with awakened Kenbunshoku Haki, and are able to use it with no known training.[10][11]

A person can also make their Haki become stronger, especially when they push themselves and their Haki to the limit and beyond in battles against far stronger opponents.[12] A person’s Haki can even grow stronger before that person actually learns to be a Haki user and even before they find out that Haki exists; for example, Blackbeard noted that Luffy’s Haki had grown stronger by the time of the mass breakout in Impel Down compared to their first meeting on Jaya.[13]

It is even possible to maintain and use Haki while unconscious, as seen when Newgate used Kenbunshoku Haki in his sleep to defend himself from Ace;[14] when Chinjao was defeated, and he still maintained Busoshoku Haki on his head after he fainted;[15] and when Luffy released a burst of Haoshoku Haki after being knocked unconscious by Kaidou.

According to Kaidou, Haki is the true defining factor that determines whether or not someone can conquer the sea, because only Haki transcends all, unlike Devil Fruit powers, no matter how powerful they may be. A clear and notable example of this rule was Gol D. Roger and Edward Newgate; Newgate was considered the “Strongest Man in the World” and he possessed the power of the Gura Gura no Mi, the Devil Fruit called the “Strongest Paramecia” which granted him the power to generate powerful quakes and shockwaves and could potentially destroy the world.[17] However, even when Newgate was in his prime, he was still matched and bested by Roger, who did not have a Devil Fruit.[18] Roger conquered the Grand Line with the power of Haki alone, achieving a feat that multiple powerful Devil Fruit users, including Newgate, Big Mom, Kaidou, and Shiki, all failed to accomplish, even decades after Roger’s death.

Furthermore, Haki also has the unique capability to reverse/nullify the effects of other people’s Devil Fruit powers.[19][20] In order to accomplish this, the user must possess a very powerful level of Haki. This application has only been displayed by individuals whose bounties are well above Beli 1,000,000,000.[21][22]

Despite its great capabilities, the Haki in a person’s body is not limitless and it can be depleted from overuse, rendering the user unable to use it for a set period of time while it regenerates.[23][24][25]

Notably, Haki originates from an individual’s spirit and not their physical body, so even if a person’s mind is transferred into another body, they would still be capable of using their Haki to the same degree that they normally can, even if the body they transferred into is not a Haki user.

The three types of Haki are: Kenbunshoku Haki (見聞色の覇気?, Observation Haki), which gives the user a sixth sense of the world around them, allowing them to sense the presence, strength, and emotions of other people, even if they are out of sight or far away. It also grants limited precognitive abilities, allowing the user to sense their opponents’ intentions and predict their actions and attacks before they happen.[3]

An advanced level of Kenbunshoku allows the user to actually foresee a short period into the future. Busoshoku Haki (武装色の覇気?, Armament Haki), which allows the user to use their own aura as armor to defend against attacks, as well as make their own attacks more potent.[3] It can also be used to bypass Devil Fruit defenses, such as the intangibility of a Logia. A person can apply the armament to a section of their body, over their entire body, and even imbue it onto their weapons.[29][3] A coating of Busoshoku will cause the coated area to turn a shiny black, and a particularly thick and powerful coating will have a flame-like pattern along its edge.

An advanced level of Busoshoku allows the user to emit the armament a short distance without a medium.[30]

A higher grade of advanced Busoshoku allows the user to make the emitted armament flow into a target’s body and destroy it from the inside-out. Haoshoku Haki (覇王色の覇気?, Conqueror’s Haki), which grants the user the ability to unleash their own willpower in order to overpower the will of others.[3] This results in victims being mentally overwhelmed by the user, with particularly weak-willed foes instantly losing consciousness. It can also apply pressure onto objects and damage them, a clash between two particularly strong Haoshoku users is capable of “splitting the heavens”. Unlike the other types of Haki which can be learned by anyone, Haoshoku is a rare ability that only one in several million people are born with the ability to use.

An advanced level of Haoshoku allows the user to infuse their conquering spirit into their weapons and physical attacks, greatly augmenting their power. Only a small handful of the most powerful Haoshoku users are able to achieve this.[31]

Another advanced level of Haoshoku allows for the ability to manipulate one’s aura or presence, which negates an opponent’s ability to sense the user with Kenbunshoku Haki.[32]

Most people who can use Haki tend to have one type that they are better at, and, as a result, focus on training and fighting with that type primarily. However, a person can improve their abilities with all the types of Haki, it just requires more work.[3]

Each type of Haki has levels of usage, so even two proficient users might not be of equal strength. Furthermore, it is possible to use at least two types of Haki simultaneously.
