Crystalocution is an ancient martial art in which opponents are destroyed via striking their metal fracture points. Among its known practitioners are Banzai-Tron, Arcee, and Greejeeber.
It is likely that Crystalocution is a nod to "Hokuto Shinken", the martial art used by the protagonist of the popular '80s anime Fist of The North Star, wherein opponents are dispatched by striking their pressure points. This in turn is based on the various less bloody real-life martial arts that specialize in utilizing the pressure points. They then tend to explode in a rather bloody fashion.
