"The Corpse" is an elite, top-secret black ops division of the Green Lantern Corps.
They are not restricted by the same rules that regular Lanterns follow, and they perform the darkest, most dangerous missions. They do not use Power Rings; instead, they swallow special coin-like disks that give them all of the powers of the standard ring for a limited time. These disks produce purple energy instead of the traditional green. Members of the "Corpse" do not wear Green Lantern uniforms, or display the Green Lantern symbol. Instead, they seem to prefer black uniforms that have no symbol.
Very few Lanterns are even aware of the existence of the "Corpse". Guy Gardner said that in all of his years in the Corps, he never heard of them, and even then his memory was erased of any mention of the Corpse afterwards.
Green Lantern Corpse Disc: Energy disks that perform similar to Green Lantern rings. They are swallowed and cover up the Corpse members in a black body suit, and emit purple energy, though it is likely this is to keep a low profile and they most likely draw upon the central GL battery in a manner similar to the rings. They can hold a five-day charge.
