Goryō are a type of predatory, vengeful, ghost with the capability to feed on, and control, electrical power. They are relatively aggressive, although their aggression decreases when in the absence of electric energy. Goryō are highly dangerous when fully charged, and some tales tell that a Goryō can destroy thousands of men in an instant if it were to gain unlimited power from a paradox reactor like a Negative Reactor.

Goryō consume power with the frenzy of a soulstarved ghost, and will even group into colonies to find power sources. These ghosts however, can be defeated. If one can destroy their Core, they will de-materialize and cease to exist in the Prime Material plane.
