Hasshoken

Hasshoken is a martial art used by the Chinjao Family.

Description
As stated by Gatz, this fighting style allows to user control vibrations around their fists or kicks to generate shock by unknown reasons. This shock is powerful enough to destroy a metal shield or defeat a strong man easily. Sai also claimed that these attacks are unblockable and reverberating. This fighting style is only used by Chinjao Family which are also members of Happo Navy, and may thusly be a secret family or special army technique.

Chinjao's Attacks

 * Buto (武頭): Chinjao jumps in reverse and headbutts the enemy. The strike is strong enough to stop Cavendish's Durandal and creates a shockwave while clashing. It was first seen used against Cavendish in Corrida Colosseum.

Trivia

 * The ability to generate and control vibrations is similar to the Gura Gura no Mi.
