"Crisis in Eternity!"
King Kull has worked out a new plot against humanity. He will pit the heroes and villains of three worlds against each other, to cause a cosmic imbalance that he hopes will alter the time-line and bring his race back to life.
(Notes: Batman & Robin of Earth-2 appear in this issue. This King Kull story line runs in Justice League of America from issues #135 to 137)
