Having found an ancient book that appears to indicate that he once defeated the JLA, Xotar travels from 11,960 to the present to test four weapons against the Justice League, in order to determine which weapon will help him defeat the Intersolar Police of his own day. But the JLA counters each of Xotar's weapons and returns him to face justice in his own time.; All man-made inventions in the world stop functioning. The Justice League summons Merlin from the Magic Dimension to help find a way to restore Earth to normal.; 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.
