Hobo Ninja

An entity, either homeless or appearing so, that practices the stealthy fictional arts of Karatsu, Tae Kung, etc. Usually carry at least one eating utensil as a weapon. You can find at least one of these in Grand Central.

The Hobo Ninja would have used his centered force to drop a mountain on you, but the soup kitchen opened early.
