Rokushiki

Rokushiki (六式) is a special, superhuman martial arts style. In the Viz Manga, they are called the Six Powers. They each made their appearances in different Chapters and Episodes, but the technique made its debut when one of the moves appeared in Chapter 342 and Episode 242. It was first introduced being used by the CP9 agents.

The strength of a Rokushiki user is measured by Doriki, which Fukuro can use his "Te-awase" to calculate with. The higher the level, the stronger each technique's potency becomes. Most of the users have their own variation of each technique, to increase their versatility and originality. Also, certain users tend to be more specialized in one technique, such as Kaku with Rankyaku, Jabra with Tekkai, Fukuro with Soru, and Rob Lucci with Shigan.

The Rokushiki style are the main style of combat for the World Government secret CP9 agents, but some Marines have also demonstrated its usage. Coby used Soru against Monkey D. Luffy, and later Vice Admirals Momonga and Dalmatian used it to confront Luffy at Marineford. It is unknown exactly how much the Rokushiki technique is spread around the Marines. Outside weapons and Devil Fruits, the series is very obscure about which technique overall Marine combatants use.

Trivia

 * The Rokuogan resembles the One Inch Punch, popularized by Bruce Lee (but invented centuries ago by Chinese martial artists).
 * While facing Enel, Luffy essentially used Kami-e to evade his attacks, due to his rubbery body.
 * Tekkai is similar to Busoshoku Haki, as both reinforce the users body in some way, the difference being that Haki is based on the user's willpower and Tekkai is based on the user's physical power.
 * Tekkai also appears to be based on the Iron Shirt technique in Chinese martial arts.
 * The Shigan technique is most likely a reference to the Shaolin Monks' fictional technique: Shaolin Finger Jab.
