Clouded in mystery for the last thirty years, this destructive kick can be delivered with the right or left leg, (and by advanced practioners, the nose and tongue). It gets its name from the fact that when properly executed, the kicking leg moves so swiftly that it casts no shadow.

The usefulness of this feature is unclear. Anyone watching for a shadow instead of paying attention to the foot advancing toward their head at speed will find that the presence of said shadow is the least of their worries.
