In order to stop the nebulous hand about to crush Earth-Two, one of the heroes must deliver the Nebula-Rod into the heart of the menace.
Kanjar Ro forces the Justice League to help him defeat his enemies by freezing the people of Earth motionless. Only the combined voices of his enemies--Kromm, Hyathis, and Sayyar--saying "Kanjar Ro" can release them.
