The Arts of Matsuo

Muay Thai:
is a martial art from Thailand that uses stand-up striking along with various clinching techniques. It is similar to other Indochinese styles, namely pradal serey from Cambodia, tomoi from Malaysia, lethwei from Myanmar and Muay Lao from Laos. Descended from my and muay boran, Muay Thai is Thailand's national sport.

The word muay derives from the Sanskrit mavya and Thai comes from the word Tai. Muay Thai is referred to as the "Art of Eight Limbs" or the "Science Of Eight Limbs" because it makes use of punches, kicks, elbows and knee strikes, thus using eight "points of contact", as opposed to "two points" (fists) in Western boxing and "four points" (hands and feet) used in sport-oriented martial arts. A practitioner of Muay Thai is known as a nak muay. Western practitioners are sometimes called nak muay farang meaning foreign boxer

Karate:
is a martial art developed in the Ryukyu Islands in what is now Okinawa, Japan. It was developed from indigenous fighting methods called te (手?, literally "hand"; Tii in Okinawan) and Chinese kenpō. Karate is a striking art using punching, kicking, knee and elbow strikes, and open-handed techniques such as knife-hands. Grappling, locks, restraints, throws, and vital point strikes are taught in some styles.

Chinese martial arts:
referred to by the Mandarin Chinese term wushu and popularly as kung fu are a number of fighting styles that have developed over the centuries in China. These fighting styles are often classified according to common traits, identified as "families" (家, jiā), "sects" (派, pài) or "schools" (門, mén) of martial arts. Examples of such traits include physical exercises involving animal mimicry, or training methods inspired by Chinese philosophies, religions and legends. Styles which focus on qi manipulation are labeled as internal (内家拳, nèijiāquán), while others concentrate on improving muscle and cardiovascular fitness and are labeled external (外家拳, wàijiāquán). Geographical association, as in northern (北拳, běiquán) and southern (南拳, nánquán), is another popular method of categorization

Jujutsu:
is Japanese martial art and a method of close combat for defeating an armed and armored opponent in which one uses no weapon, or only a short weapon.

"Jū" can be translated to mean "gentle, supple, flexible, pliable, or yielding." "Jutsu" can be translated to mean "art" or "technique" and represents manipulating the opponent's force against himself rather than confronting it with one's own force. Jujutsu evolved among the samurai of feudal Japan as a method for defeating an armed and armored opponent in which one uses no weapon, or only a short weapon. Because striking against an armored opponent proved ineffective, practitioners learned that the most efficient methods for neutralizing an enemy took the form of pins, joint locks, and throws. These techniques were developed around the principle of using an attacker's energy against him, rather than directly opposing it.

Haki (覇気, Haki? literally meaning "Ambition"):
It is not that different from the normal senses. However, most people do not notice it or fail to awaken it. Broadly, there are two types of Haki common to everyone, given the proper training; however, there is a third type that only a certain group of "chosen ones" are said to possess.

Haki is separated into three categories: Kenbunshoku Haki, which grants users a sixth sense of the world around them and limited precognitive abilities; Busoshoku Haki, which allows the user to use their spirit as armor to defend against attacks or to make their own attacks more potent; and Haoshoku Haki, a rare type of Haki only one in a million can use which grants the user the ability to overpower the will of others. Most people who can use Haki tend to have a type they're better at and as a result focus on that type. However, a person can improve their abilities with all the types of Haki, it just requires more work.

Kenbunshoku Haki (見聞色の覇気, Kenbun-shoku no Haki?, literally meaning "Color of Observation"), also known as Mantra (心綱 (マントラ):
is a form of Haki that allows the user to sense the presence of others, even if they are concealed from view or too far to see naturally. When using this type of Haki, one can predict an opponent's moves shortly before they make them, thereby making the attack that much easier to evade. This prediction appears to the user as an image or brief "premonition" of what the opponent will do in the user's mind's eye, and the damage the user will take if the attack actually "hits". It appears that the more killer intent the enemy has, the easier they are to predict. Although, more skilled users can predict future moves whether there are ambient murderous intents or not.

Busoshoku Haki (武装色の覇気, Busō-shoku no Haki?, literally meaning "Color of Armaments"):
allows the user to create a force similar to an invisible armor around themselves. This allows the user to defend against attacks that would otherwise cause them harm. Only significant physical force can overcome this defense; for example, Luffy striking Boa Marigold hard enough with Gear Second techniques to send her reeling. The invisible armor can take on many forms such as Luffy hardening his fist to the point where it changed color.

With training, it can be further honed into a weapon with which to strike others. It can be used to augment the user's own attacks, projected ahead of the user as pure brute force, or imbued in weapons to increase their effectiveness. Any attack enhanced by Busoshoku Haki hits immensely harder than it would normally without it.

This type of Haki also has the ability to bypass the powers of a Devil Fruit user, touching the "substantial body" beneath whatever protection the fruit provides, such as the case of body-altering Devil Fruits such as Logia users. Busoshoku Haki works independently of the user's Devil Fruit, as shown when Luffy uses it to enhance his Gear Third attack underwater. This type of Haki may not be equipped to attacks that are not from one's body except for weapons (like Kizaru's laser beams, Marco's flames or any other Logia attack). So, those who do attack with parts of their body can combine their Haki and Devil Fruit powers.

Haoshoku Haki (覇王色の覇気, Haō-shoku no Haki?, literally meaning "Color of the Conquering King"):
is a rare form of Haki that cannot be attained through training and only one in a million people carry it. It was first demonstrated by Shanks, when he used it to scare off a Sea King. Later on, during a meeting with Whitebeard, he used it to knock out most of the crew and cause physical damage to the Moby Dick, which the few still standing attributed to his superior Haki. Luffy first displayed the effects of this type of Haki against Duval's bull, Motobaro, much to everyone's confusion. He displayed it again on Amazon Lily while battling the Boa sisters, knocking out a large portion of the audience observing the match, despite all of them being accustomed to regular Haki usage. This is also the first time it is referred to by name. Luffy's exhibition of it during the Marineford War was enough for the Marine Admirals to be wary of him that they prioritized his elimination after that.

After the time skip, Luffy is proficient enough to tame monsters, as well as knock out a selected group of individuals without affecting any of the bystanders using Haoushoku Haki, displaying his new-found proficiency in the skill.

This type of Haki grants the user the ability to overpower the wills of others. The most common usage in the series so far is knocking those with weak wills unconscious. Whilst inexperienced users are restricted to merely overpowering the will of one individual or blindly knocking out weak-willed people around them, those with more expertise can pick out weak-willed individuals in a large group and knock them out without affecting those around them. However, those with stronger wills can resist or even ignore the effects of Haoshoku Haki. According to Rayleigh, while this type of Haki cannot be attained through training, it can be improved through training, as it grows as the users spirit grows. It seems that upon recovery, victims of Haoshoku Haki experience the sensation of chills running through their body. However, it presumably wears off after a short period.
