Hook (Gōu 勾) is the first of the 12 keywords of Mantis Boxing. The keyword formula houses the principles that define the art. They have been passed down from generation to generation for hundreds of years.

A Praying Mantis seizes it's opponent with it's large arms and hooks. It pulls it's prey off balance and devours it on the ground. When observing the mantis against a larger foe, one can see the mantis pounce, take the back, use it’s legs to hold on, and continually gain control of it's opponent while it bites and gains better hook positions to keep it safe.
